Technology for laying soft roofs made of bitumen shingles: step-by-step instructions. Do-it-yourself soft roofing with step-by-step photos: Instructions for action How to properly cover a soft roofing roof

The basis for soft bitumen shingles is fiberglass, bitumen and stone chips. The popularity of the material was ensured by its complete immunity to corrosion and water resistance. It can be used on any roof shape, including domes. Basalt powder protects from heat and ultraviolet radiation, protects the bitumen base from precipitation and mechanical damage. Fiberglass provides the strength of the material, and bitumen provides complete waterproofing. Due to the versatility of the coating, many are interested in how to cover a roof with a soft roof with their own hands.

Among the advantages of bitumen shingles:

  • ease of transportation and unloading due to low weight;
  • a small percentage of waste during installation, even on a curved surface;
  • soft material absorbs the sound of rain;
  • resistance to high and low temperatures;
  • plasticity and flexibility, allowing you to create various geometric shapes;
  • long operation;
  • lack of electrical conductivity.

Manufacturers of soft roofing offer several forms of tile cutting and many colors.

Tools for work:

  1. Hacksaw.
  2. Roulette.
  3. Hammer.
  4. Trowel for mastic.

Where to start styling

You can cover the roof with tiles by scrupulously following the technological sequence of work. The first stage of arrangement is preparing the foundation. The waterproofing of the roof is affected not only by the quality of the bitumen shingles, but also by the sheathing. The base must be extremely flat, strong and rigid. The pitch of the sheathing depends on the angle of the slope and the strength of the winds in the region; it is 50–100 cm. The basis of sufficient strength will be edged boards made of softwood, OSB, and moisture-resistant plywood. To protect against rotting, materials are treated with an antiseptic. A gap of 3 mm is maintained between adjacent sheets for thermal expansion. The material used must be dried, humidity up to 20% is allowed. The boards are joined above the supports, the length of each spans two spans of rafters. The slabs are laid staggered and fixed with self-tapping screws.

To avoid metal corrosion, use galvanized nails.

Ventilation for soft roofs

To ensure air circulation, holes are left at the highest point (on the ridge) and at the junction of the cornice. Ventilation allows you to reduce the temperature in the attic, remove vapors and condensation from under the roof, and avoid ice in winter. Holes for natural ventilation are evenly distributed along the length of the ridge and cornice.

The base should not be adjacent to the waterproofing, so it is important to make a gap of 5 mm.

Construction of the lining layer

When the roof slope is from 12 to 18 degrees, roll insulating material is spread over the entire roof. They begin work from below, from the cornice, laying the canvas parallel to it. The joints of the lining layer are overlapped and nailed every 20 cm. All seams are sealed with glue. If the angle of inclination is large enough, then individual areas are isolated: skylights, ridges, valley, cornices and ends. On valleys, the lining material is spread on both sides, its width is at least 50 cm. On the eaves overhang, the size of the lining material is 60 cm.

Additional items

The edges of the sheathing need protection from rain. To do this, a metal drip is nailed along the cornice. It is attached to the cushioning layer with an overlap of 2 cm, nails are driven in every 10 cm.

The ends are covered with special metal pediment strips; they are attached in the same way as cornice strips - overlapping and on top of the insulating layer.

The valley is an area where leaks are possible; to prevent them, a valley carpet is laid. It is made of polyester fabric, treated with bitumen and basalt topping. It is fixed to the roof using mastic and nails, which are driven 3 cm from the edge. Valley carpet matched to the same color as soft tiles. The edge of the asphalt shingles is trimmed to leave 15cm of carpet exposed. This is necessary to create a gutter along which the flow will flow. rainwater. The described method is considered optimal.

Nuances you need to know

  1. It is recommended to carry out work on laying rows soft tiles at an air temperature of +5 degrees (°C). During frosts it is impossible to ensure normal adhesion of bitumen. In addition, the material becomes brittle and does not allow creating a curved structure. The connection of tile shingles to the base and to each other occurs when heated by solar heat.
  2. Working at low temperatures, the tiles are brought in in small batches, and the bulk is stored in a warm room.
  3. You cannot leave a soft roof under scorching sun so that the bitumen does not melt.
  4. Bituminous shingles have slight differences in color; it is better to take shingles from different packs, then the transition will be smooth.
  5. Do not clean the roof with shovels, as this may damage the coating. During installation, it is necessary to set the slope angle to prevent snow from accumulating on the roof.

Before starting work with flexible tiles, mark the base. Horizontal lines are drawn in increments of 70 cm (five rows of tiles), vertical markings are equal to the size of the shingles. This will allow them to be laid in even rows. The cornice row of asphalt shingles is laid first. It is made from a universal self-adhesive soft roof. Before starting work, remove the protective film. The sheets are laid end to end and secured with nails along the perforations. The fixation sites overlap with the next row.

Installation flexible tiles start from the middle of the cornice and move to the ends. The first row should overlap the tiles laid above the eaves, the distance between their lower edges is 1 cm. When the slope slopes up to 45°, 4 nails are used to fasten one tile; for a higher value, 2 nails are added for reliable fixation.

The head of the nail should be flush with the surface of the asphalt shingles and not cut into it.

The petals of the next rows should be at the same level and cover the perforation of the previous row. Depending on the cutting of the tiles, the offset is selected next row. This allows you to create a chaotic or ordered pattern. Most models are laid with a half-petal offset. Markings made before installation will allow the continuation of rows of flexible roofing that were interrupted dormer windows or chimney pipes. At the ends, the soft tiles are cut off, not reaching 1 cm from the strip, and its edges are glued with a layer of mastic 10 cm wide and nailed.

When cutting the material, plywood should be used as a backing; this will protect against accidental damage to the bottom layer of soft tiles.

The dimensions of the gutter are noted on the valley carpet; it can be from 5 to 15 cm. It should be noted that a 30-centimeter zone is formed near the gutter, which cannot be nailed. The tiles are trimmed along the border of the gutter. Top corner The shingles are cut to remove water. Using a trowel, apply mastic to the edge of the tile and attach it to the carpet.

Features of finishing of the ridge and roof ribs

To make shingles suitable for a ridge, it is necessary to cut ordinary asphalt shingles into three parts. On the edges of the roof, ridge tiles are laid from bottom to top. After removing the protective film, it is glued and fixed with four nails two centimeters from the edge. The next part is glued with an overlap of 5 cm.

Ridge shingles are laid to face the prevailing winds. For ease of installation, each part of the ridge tile is heated in the middle and bent along the edge of the bar to form an angle. The tiles are attached to a bitumen base and 4 nails. In the ridge row, soft tiles are overlapped on top of each other, like ordinary ones.

To ensure sealing at the junctions with antennas, chimney or ventilation pipes, a valley carpet or galvanized metal is laid. When choosing a carpet, a plinth is installed on the pipe. The pattern of the material used is laid with an overlap of at least 20 cm onto the ordinary tiles. The back side of the carpet is coated with bitumen mastic. It is glued along the perimeter of the pipe, the places of contact with the tiles are treated with bitumen mastic to a depth of 10 cm. The top of the carpet, which extends onto the pipe, is covered with metal strips.

To install roof penetrations, special passage elements are purchased. Such an element is laid with an overhang of 2 cm onto the roof. A hole is cut in the base. The skirt of the element is glued with mastic and nailed. Its surface is covered with bitumen shingles, and the remaining joint is covered with mastic and sprinkled with basalt chips to protect it from ultraviolet radiation.

A properly laid soft roof will provide reliable protection for your home for at least 30 years.

Detailed video on installation of flexible tiles:

Hot mastic is heated to 220 degrees, after which various mineral fillers are added to it:

Before installation, the roofing material itself is laid on the base and rolled out over the entire surface.

To glue the canvases, it is necessary to use mastics that are designed for a specific material. roll roofing. If a bitumen roof is used, then it is glued with bitumen mastics, tar roofing is glued with tar compounds.

Lay individual strips of material end to end. In this case, when laying subsequent layers, it is necessary that the joint of the previous layer be covered with a new layer. With a slope of less than 5%, the joint must overlap by at least 10 cm.

During the installation process, not one soft roofer takes part, but two:

The brush operator's responsibilities include applying mastic to the base and inner surface rolls The layer glues and adjusts the sheets to the prepared base. Already laid canvases are rolled on top with a roller. This is necessary to ensure good contact with the surface (read also: “Installing a soft roof - advantages of use”).

Installation of roll roofing includes checking the quality of sizing of materials. To do this, carefully tear off one layer from the other. A small tear is acceptable. If the material sheet has deviated to the side, it must be moved in the desired direction without tearing it away from the previous layer. If the layer has already stuck and it is impossible to move it, then the already glued part is cut off and re-glued. At the same time, monitor the size of the required overlap.

If swelling occurs over the area of ​​the material, they must be pierced with an awl or trimmed with a knife. After this, this place is pressed to the base until mastic flows through the hole. This will seal the surface after it hardens. The canvases are laid in layers, and if cold mastics are used in the work, at least 12 hours must pass between laying layers.

Installation of roll roofing is a labor-intensive process, which also requires a lot of physical labor. That is why various mechanical roof installation devices are increasingly being used. Such equipment is used on large objects where the estimate for a soft roof amounts to tens of thousands of rubles. That is, in cases where the use of manual force will be costly.

Installation of roll roofing, detailed in the video:

Repairing a roll roof is not a difficult task. Even people who have no experience in roofing work can cope with the procedure for eliminating defects in such a roof (read also: “Repairing soft roofs”).

To repair a roof section, it is necessary to remove deformed elements that have lost their insulating qualities. Instead of the removed section of the rolled roof, a new covering is laid. At the same time, it is important to comply with the rules and regulations for the arrangement of such a roof. This means taking into account the slope of the roof and observing the overlap.

Soft roll roofing: photo and technology for installing a soft roll roof with your own hands

Preface Soft roll roofing is one of the types of covering flat roofs.

Most often this material is used for outbuildings or buildings. industrial use.

Soft roll roofing is one of the types of covering flat roofs. Most often this material is used for outbuildings or industrial buildings. By following the technology of laying soft roll roofing, it is possible to ensure a structure on summer cottage reliable protection, however, due to the limited color range and structure of the material, it will not be possible to give originality to the coating.


Rules for laying rolled soft roofing with your own hands

Installation of soft roll roofing is usually used where other roofing materials cannot be used, for example on flat or gentle slopes.

According to the rules for laying rolled soft roofing, it should be installed in several layers: with a slope from 0° to 5°, four layers of material must be laid, with a slope from 5° to 20° - three layers, and if the slope exceeds 20°, then two layers are sufficient .

At the same time, the maximum slope angle of the roof slopes for rolled materials should not exceed 45°.

When installing a roof made of soft rolled materials, you must remember that they are laid on a sheathing that does not have gaps.

In the event that it was used only unedged board and it was not possible to avoid gaps, gaps wider than 10 mm should be covered with strips of galvanized sheet. The prepared sheathing must be absolutely even and smooth.

There should be no uninsulated nails, protruding knots or wood fragments that could damage the roofing material on its surface. Moisture-resistant plywood is suitable for these purposes, but it will increase the cost of the roof. In this case, the installation of a soft roll roof is carried out on a concrete base (for example, concrete screed or reinforced concrete floor slabs), it must be dry, without potholes or bumps. All ends of boards or floor slabs through which rolled materials will be bent should not have sharp corners to avoid tearing and chafing.

After cleaning the surface from debris and dust, it is primed with roofing mastic.

Using the technology of installing soft roll roofing with your own hands, strips of material are laid in one direction.

On a roof with a slope of up to 20°, soft roof panels are glued horizontally, that is, along the eaves, perpendicular to the water flow. For flat roofs, the sequence of installation of the panels does not play a special role, but if there is even a slight slope, then work begins from the very bottom. On roofs with a slope of more than 20°, the panels are rolled out vertically, that is, perpendicular to the eaves, in the direction of water flow.

According to technology, soft roll roofing is laid with an overlap.

In this case, the joints of the inner layers must be at least 70 mm, and the top ones - at least 100 mm. In addition, overlaps in adjacent layers should not be located one above the other, and they should be spaced half the width of the roll.

Technology for laying soft roll roofing using mastic

In the case when a soft roof is made using mastic (bitumen, bitumen-polymer or polymer) as an independent roofing material, no seams are formed on it.

In addition, roofing mastic has a high elongation coefficient, which ensures the integrity of the coating during seasonal roof movements and other loads, for example, if snow accumulates on the roof. However, this method also has its drawbacks - it is very difficult to obtain a mastic coating of the same thickness over the entire surface of the roof.

Look at the photo: soft roll roofing is usually reinforced with fiberglass or glass mesh with an approximate cell size of 4 x 4 mm.

The mastic is usually applied using a special sprayer. The number of layers also depends on the slope of the roof slopes: up to 15°, two reinforcing layers are sufficient, and from 15° to 25° - three layers of mastic and two reinforcing layers. In this case, the installation of each subsequent layer is carried out after the previous one has dried.

Installation of flat roofs of various types

The roof ridge, valleys and valleys, eaves overhang, as well as junctions with walls and vertical protruding parts are reinforced with several additional reinforcing layers. It is recommended to protect the top layer of mastic coatings with a layer of paint. However, some types of modern mastics do not need a protective layer, since they are painted in the mass and have the necessary decorative properties, and the material itself is quite resistant to atmospheric influences.

And here protective layer from mastic with fine gravel or decorative coating It’s still worth laying, especially for habitable roofs.

Rolled materials for fused roofing

Fused roofing materials in roll form are in demand for the construction of flat and pitched roofs and for waterproofing hydraulic engineering and underground structures.

They have a multilayer structure, protection from moisture is provided by a layer of modified bitumen, tightness is achieved by heating it and pressing it tightly to the surface.

The material is valued for its availability, ease of transportation and installation process, safety of operation, high resistance to temperature, atmospheric, mechanical and biological influences.

The technology is considered reliable; the waterproofing roofing carpet obtained by fusing effectively protects the structure from getting wet, fire and other negative factors for at least 10 years.

Structure and composition of the material

The basis of the fused roof is modified bitumen; the material has a multilayer design:

  • The bottom layer is presented as polyethylene film, in addition to protecting against sticking, it serves as an indicator of achievement optimal temperature heating
  • The next layer is the working layer, the binder layer.

    It is this that softens during installation.

  • Reinforcing base made of fiberglass or polyester threads.
  • External bitumen or bitumen-polymer layer.
  • Protective coating of mineral crumbs.

This structure guarantees tightness, especially when fusing several layers. The base is bio-resistant and made of randomly directed threads, which indicates high tensile strength.

Types of bitumen

The working surfacing and protective outer layers are made of modified bitumen with two possible types oxidizing additives: rubber (styrene-butadiene-styrene) or atactic polypropylene.

The first modification is valued for its elasticity; this property is preserved even in extreme cold (up to -40 ° C). Bitumen with APP plastic are distinguished by their rigidity and heat resistance (melting temperature is 150 ° C), their optimal scope of application is in the hot climate zone.

Regardless of the composition, modified bitumens are resistant to temperature changes and moisture; polymer-based materials are superior in service life and strength.

Such a binder does not need to be melted to a liquid state; to achieve a tight fit, it is enough to heat it evenly.

Reinforcing materials

Currently, a fragile cardboard or asbestos base is not used for the manufacture of fused rolled roofing; the reinforcing layer is made of polyester, fiberglass or fiberglass.

The type of base is indicated in the first letter of the marking.

    Polyester (E) It is considered the most reliable and durable base; the threads in it are distributed randomly.

    Thanks to this, the roofing material has an elongation at break of up to 60%, the minimum applied force for breaking is 35 kgf/cm. The only drawback of polyester is the high price; this variety is the most expensive.

    Fiberglass (T) the base is characterized by high strength (tensile force - from 80 kgf/cm), the best characteristics are observed in brands with frame fiberglass.

    The downside is low elasticity, elongation at break reaches only 2%. Such a coating when sheared or deformed roofing structure does not tear, but simply moves away from the surface.

    Fiberglass (X)- has minimal strength - a breaking force of 30 kgf/cm with a complete absence of elasticity. This is the cheapest variety; problems may arise during its transportation (cracking or tearing of the material). It is not recommended to be installed on complex or moving roofs, or on frequently used structures.

Types of toppings

The main purpose of this layer is protection from precipitation, mechanical external influences and ultraviolet radiation. For sprinkling, chemical inert materials are used: sand, basalt, slate, mica, ceramics.

Depending on the shape and size of the fractions, dusty, fine-, medium-, coarse-grained and scaly types of mineral chips are distinguished; the first type protects the material from sticking together in a roll.

Recently, welded roofing coated with foil or polymer film has been produced, which is not inferior to varieties with mineral chips in terms of reliability of protection from external factors. There are brands with double-sided powder coating; they are used as the bottom layer of roofing carpet.

Installation principle

The installation technology is simple: the bottom layer of rolled roofing is heated with a burner until the inscriptions on the indicator film disappear (burnout), the material is rolled out onto a previously prepared base and pressed with a roller.

Installation of a built-up roof is quick, but on pitched roofs with a slope, at least three people will be required. Required terms are: treating the base with primers, laying the roof overlapping, laying at least two layers (the smaller the angle of inclination, the thicker the roofing cake), checking the quality of the fit.

Soft roof installation technology

The canvases are laid offset, the joints should not coincide. If a poor-quality area is detected, the bitumen roofing should be reheated and the installation carried out again.

Application area

This is a multifunctional building material used for waterproofing various types of structures:

  • Flat and pitched roofs with slope angles up to 30°.
  • Hydraulic structures: wells, swimming pools, sewer canals.
  • Foundations and underground elements of buildings, including tunnels and bridges.
  • Ceilings and floors in rooms with high humidity: bathroom, bath, baths.

The main purpose is roofing: repair or basic.

Fused materials can be used as a base for slate, tiles and other types of roofing or laid as an independent protective coating. In the first case, one layer is enough, in the second - from 2 to 4 (depending on the angle of the roof).

The operational characteristics of rolled roofing are suitable for use in all climatic zones of the Russian Federation, including northern ones.

Construction of any industrial building or a residential building is completed by the construction of a roof, thanks to which a kind of barrier is created that prevents moisture and snow from entering the room, and also retains warm air. The comfort and coziness of staying in the building depends on how correctly and efficiently the roll roofing is installed.

In ancient times, builders ensured the tightness of the roof structure using clay and sheet iron (more details: “ Roofing iron leafy - characteristic"). However, the fragility of these materials led to the rapid loss of the original properties of the roof and its constant repair.

Soft roofing - roll: device technology

As construction progressed, new materials began to be developed and modern technologies for their installation were used.

One of important elements, which is included in the construction of roofs made from roll materials, is waterproofing for the roof.

It protects the roof space from water penetration, which has a positive effect on maintaining the high quality of the wooden rafter system, as well as the attic floor.

Here you also need to take into account the design of roll roofing, according to which the waterproofing roofing covering will be selected.

Owners of private houses, as a rule, prefer a gable or broken structure, so in this case waterproofing layer made from membranes with a base of polyethylene or polyvinyl chloride, as well as roofing felt supplied in rolls (read: “Roof waterproofing device - characteristics of materials”).

If the building is being erected with a flat roof, then the listed materials are no longer suitable for work.

In this case, the installation of roll roofing is carried out from fused materials.

What roll materials can be used for roofing installation

Depending on the various characteristics There are several classifications of roofing coverings.

Let's look at some of them.

Depending on the method of application there are:

  • materials with a bitumen base - you can achieve a tight connection when laying them using special mastics, which can be hot or cold;
  • materials on an adhesive polyethylene base, protected by film.

    When laying on the roof surface, the film is removed.

  • welded materials. In this case, roll roofing - its installation technology is somewhat different from the two listed methods of applying the material; it is laid using a gas roofing burner.

Depending on the use, materials are selected:

  • for single-layer coating;
  • for multilayer coating.

The former are characterized by the presence of multilayer fiberglass with the addition of polymers and bitumen.

The top layer of such material is made of basalt, sand, foil or shale topping. The most common option is to install a roof made of hydrostekloizol, stekloizol, rubitex, fiberglass, prorofikrom, masterkrom.

List of properties characteristic of rolled roofing

These roofing coverings cannot be classified as elite, but they are what developers use.

The possibility of quick and convenient installation significantly speeds up the pace of work. Also, another advantage of the materials is that the repair of rolled roofs can be performed on both flat and flat (no more than 11 degrees slope slope) roofs, which is not possible with any coating, including ondulin.

The elasticity of the roll roofing composition prevents the appearance of cracks, makes the fabric very durable, and improves sound insulation. Compliance with European standards, as well as environmental friendliness of the materials, allows them to be used in any conditions. Experts highly value the availability of high thermal insulation qualities fabrics that are preserved even under prolonged ultraviolet radiation.

Description of roll covering installation technologies

Since each coating has its own characteristics, their installation is carried out differently, which can be seen from the installation photo.

Laying a built-up roof

Before you carry out repairs on roll roofing - the technology of which boils down to applying materials using the fusing method, you should know that they are produced by TechnoNIKOL and Isoflex.

This method is absolutely not suitable for attaching the covering to wooden floors and rafters, but is intended for a flat or flat roof (for more details: “Design of a built-up roof - technology”).

The best option is to use built-up roofing felt, also called Euroroofing felt, which contains fiberglass with a bitumen coating on both sides (more details: “Euroroofing felt - laying technology: installation process”).

Its difference from outdated materials is observed in the strength of the base, so the roofing covering will last longer than its economical counterparts.

Installation sequence:

Fastening the roofing with mastic


Possibilities of multi-layer roofing carpet

Due to the design features, the roof must be reliably protected from wind, rain, snow, and temperature fluctuations.

To achieve this, roofing from roll materials is performed in several layers. Ruberoid or other selected roll material is laid in 2-5 layers, their number is determined by the slope of the roof.

TechnoNIKOL https://www.youtube.com/embed/wofS8o7z9E4

If the work is carried out on a flat roof, then it is recommended to lay as many layers as possible, then the coating will easily withstand any load that arises during operation and repair of the roof.

If the roof slope is up to 2-3 degrees, the best option would be to create a four-layer cake. If the angle of the slope reaches 10 degrees, then a three-layer roofing material coating will be needed, but if it is more than this value, then a two-layer coating - underlying and external.

Technology of laying profiled sheets on the roof
How to properly lay sheets on the roof

Profiled sheets have a number of advantages, which makes it possible to design various roofs with their help.

Having figured out how to properly lay corrugated sheeting on the roof, you can implement this work yourself.

What is a roofing cake?

In the process of studying the question of how to properly lay corrugated sheets, you will need to understand the nuances of arranging the roof structure.

At first construction work installed after erection of the roof rafter system. This procedure must be carried out in compliance with all technical standards, since the rafters are subject to significant static and dynamic loads. It is better if this work is performed by specialists who have the appropriate skills in designing and installing the structure.

Before laying corrugated board over the finished rafter system, you need to decide on the lining material.

This is directly influenced by the type of roofing structure and the characteristics of the material itself. For example, if the role of waterproofing is performed by a volumetric vapor-permeable diffuse membrane, there is no need to install a vapor barrier. Some insulation materials withstand moisture and are capable of transmitting steam.

Roofs can be warm or cold - this is influenced by the purpose of the room.

If we're talking about O attic room, then the roofing pie will include the following elements:

  1. Vapor barrier.
  2. Internal lathing.
  3. Insulation.
  4. Waterproofing.
  5. Counter-lattice.
  6. Lathing.
  7. Profiled sheet.

A cold roof requires only a waterproofing layer, which must have vapor-permeable characteristics.

This will allow excess moisture in the room to leave it freely: in this way the attic will be saved from the accumulation of dampness.

For arrangement cold roof it takes much less time, effort and money than building an insulated structure.

After arranging the roofing pie, you can lay the roof with corrugated sheeting.

We lift the corrugated sheet to the installation site

Before laying the corrugated sheet on the roof, it must be lifted there in an undamaged condition. Usually short sheets are lifted quite easily due to their good vertical rigidity.

However, since it is desirable to lay corrugated sheets with a small number of joining sections, the length of the material used for these purposes can be 5 meters or more. This implies the presence of certain difficulties in lifting such a sheet - the slightest careless movement can lead to its deformation or breakage.

To lift corrugated sheets onto the roof, one of three methods is usually used:

  • Construction crane.
  • Suspension.
  • Guides.

The first method is considered the simplest, but at the same time the most expensive.

The roofing material is first laid on pallets, and then lifted to the surface of the mounted sheathing by a crane.

It is better to lower pallets on the roof in the area that will be sheathed in last resort. This will make it possible to avoid the time-consuming procedure of moving them from place to place.

Using hangers is the most inexpensive way to deliver corrugated sheets to the installation site. However, its implementation will require quite a lot of time. Having lifted a pack of material onto the roof, you need to put it on a pre-prepared place on top of the sheathing.

It is also important to think about how to secure this pack to the roof. During the implementation process, the long side of the corrugated sheet is installed on the base, and the last wave along the top is equipped with a pair of wooden blocks located opposite.

It is important to do this so that they protrude slightly on both sides.

Screws, metal brackets or clamps are usually used to tightly fix the bars.

To lift the sheet up, a rope is tied along the edges of the wooden blocks. After this, you will need to completely dismantle the entire fastening system.

In the third case, special wooden guides are used. The laying of two wooden blocks is carried out in such a way that they fall inside the outer waves on the inside.

To fasten the guides together, wooden boards are used, in increments of 1-1.5 m. The finished improvised ladder is placed so that one side rests on the roof, and the other on the surface of the ground. The angle of inclination of the structure should approximately coincide with the angle of inclination of the roof.

By tying the profiled sheet on both sides in the area of ​​the long edge with a rope, you can drag it onto the roof. To avoid scratching the material, the guides are covered with tarpaulin or any other dense fabric.

How to lay out profile sheets

When understanding how to properly lay corrugated sheets on the roof, you cannot ignore the basic installation schemes for the material. The layout of the corrugated sheets is thought out in advance: for this you can use a specialized program or just a sheet of paper.

Having an accurate diagram will significantly speed up the installation procedure, and will also make it possible to do without unnecessary trimming.

The starting point for laying roofing sheets is the lower edge of the overhang, on either side. If you need to arrange a single-pitched or gable roof, then due to the simplicity of the work, a preliminary circuit is usually not made.

Using a profiled sheet with a capillary groove will require special care: the area with the groove must be placed under the adjacent sheet.

List of additional elements for corrugated sheets

You need to install some additional elements on the roof surface; how to properly lay corrugated sheets on the roof will not work without them. Mainly for these purposes, cornice strips, valleys and abutment strips are used.

With the help of a cornice strip, the front board is protected from climatic moisture, and the attic is protected from rain getting inside it during strong gusts of wind. It is attached on top of the front board using self-tapping screws, in increments of 2-2.5 m.

The overlap used is from 100 mm. The eaves strip must be placed under the waterproofing material: this will allow moisture that has penetrated under the roofing to drain freely.

The valley strip is also installed before laying corrugated sheets on the roof.

It consists of two parts - external and internal. The internal component is under the coating. The junction area should be covered with an additional layer waterproofing material or special tape. With the help of adjacent strips, passages are organized through roofing surface various pipes and other elements.

The lower junction bar must be placed under the corrugated sheeting at a distance of 20 cm.

Technology of laying profiled sheets on the roof

Before laying the roofing material, check the plane of the slopes with a cord. If differences of more than 5 mm are detected, they are eliminated by using pads under the sheathing, or cutting out suitable grooves in the counter battens. This step should not be skipped, since it is quite difficult to lay corrugated sheets correctly on an uneven base.

On roof slopes of a simple rectangular shape, any lower corner can be the starting point for installation. A pair of self-tapping screws are suitable for temporary fixation of the sheet. The installation of the first row of profile sheets is carried out in such a way as to achieve complete overlap of the eaves overhang. The dimensions of the protrusions beyond the edges should be within 50-60 mm. This is especially true if a drainage gutter is laid on top of the roof eaves. If the drainage system is not used, the corrugated sheet protrusions must be increased to 200-300 mm.

How to properly lay sheets on the roof

Having mounted 2-3 sheets included in the first row, you can move on to the second row. In this case, it is necessary to ensure that the sheets of the next row overlap by 150-200 mm the sheets of material in the previous row.

The size of the overlap depends on what is being laid on the roof in this case. For these purposes, there are special tables in which the most common coating grades are calculated.

Since laying the roof correctly with a profiled sheet is quite simple, some craftsmen immediately use finishing fixation, without checking the evenness of the installation along the overhangs.

It is for this reason that unsightly distortions in the roofing material occur. To correct such errors, you cannot do without unscrewing the screws and rearranging the sheets. It is most reliable to carry out the final fastening of the corrugated sheeting after inspection.

If it is necessary to design a triangular or trapezoidal slope, installation is carried out according to a different algorithm.

Do-it-yourself roll roofing installation

In this case, the starting point for installation is central part the slope or line running between the edge of the ridge and the eaves. After this, both sides serve as the installation direction.

As fastening of profiled sheets on roofing sheathing special roofing screws are used. They usually have a hex head and a drill-like tip.

To attach the corrugated sheet to the sheathing, the bottom wave of the profile is used. The place where the self-tapping screws are screwed is each wave on the cornice and the overlap area. The entire remaining surface is equipped with fasteners every 300-400 mm, using a checkerboard pattern for their arrangement.

To install the ridge on the sheathing, you will need long screws.

Roofing made of bituminous soft tiles is easy to use, durable and aesthetically pleasing. Its big advantage is that independent installation is quite possible. The technology is not the most complicated, the weight of the fragment is small, it is attached to an adhesive base, and is additionally fixed with roofing nails. So you can do the installation of soft tiles with your own hands even alone.

Roofing pie for soft tiles

The attic under the roof can be warm or cold, depending on this the composition of the roofing cake changes. But its part from the rafters and above always remains unchanged:

  • waterproofing is installed along the rafters;
  • on it - bars with a thickness of at least 30 mm;
  • solid flooring.

Let’s look at these materials in more detail - what and how to make them from, what features each of them has.

Waterproofing

Waterproofing membranes come in one, two and three layers. Single-layer membranes are the simplest and cheapest, they perform only a double task - they do not allow moisture to pass into the room and release vapors to the outside. In this simple way, the attic is not only protected from the penetration of condensation or precipitation that suddenly seeps in, but also excess moisture that accompanies human activity is removed from the air. Single-layer membranes are poorly represented on the market. They are practically produced by one company - Tyvek.

Two- and three-layer membranes are more durable. In addition to the waterproofing layer, they also have a layer that gives greater tensile strength. The third layer, if there is one, is the adsorbent layer. That is, even if a drop of condensate forms on the surface of the membrane, this layer absorbs it, preventing it from spilling onto other materials. With sufficient ventilation, moisture from this layer gradually evaporates and is carried away by air currents.

Three-layer membranes (for example, EUROTOP N35, RANKKA, YUTAKON) are desirable if your attic is insulated and mineral wool is used as insulation. It is afraid of getting wet and when humidity increases by 10%, it loses half of its thermal insulation properties.

If under the soft tiles there is cold attic, it is advisable to use a two-layer waterproofing membrane. In terms of strength, it is much better than single-layer ones, and the price is only slightly more expensive.

Lathing

Sheathing strips are placed on top of the waterproofing film, parallel to the overhang. They are necessary to create a ventilation gap. It will maintain normal humidity of roofing materials.

The sheathing is made from coniferous boards (mainly pine). The thickness of the boards is at least 30 mm. This minimum clearance, which will ensure normal air movement in the under-roof space. Before laying, the wood must be treated with an impregnation that protects against pests and fungi; after this layer has dried, it is also treated with fire retardants, which reduce the flammability of the wood.

The minimum length of the board for sheathing is at least two spans of rafters. They are attached and connected over rafter legs. You cannot connect them anywhere else.

Flooring

The flooring for soft tiles is made continuous. The materials are selected based on the fact that nails must be driven into it, therefore they are usually used:

  • OSB 3;
  • moisture-resistant plywood;
  • tongue and groove or edged board of the same thickness (25 mm) with a moisture content of no more than 20%.

When laying flooring under soft tiles, gaps must be left between the elements to compensate for temperature expansion. When using plywood or OSB, the gap is 3 mm, between edged boards 1-5 mm. The sheet material is fastened with seams staggered, that is, so that the joints are not continuous. The OSB is secured using self-tapping screws or rough nails.

When using boards as flooring, you need to ensure that tree rings the wood was directed downwards. If they are positioned in the opposite direction, they will bend in an arc, the soft tiles will lift, and the tightness of the coating may be compromised. There is one more trick that will keep the wooden flooring level even if the moisture content of the boards is above 20%. When laying, the ends of the boards are additionally secured with two nails or self-tapping screws driven close to the edge. This additional fastener will prevent the boards from bending when drying.

The choice of thickness of material for flooring under soft tiles depends on the pitch of the sheathing. How more step, the thicker the flooring is needed. The best option- frequent steps and thin slabs. In this case, a light but rigid base is obtained.

Another point concerns the installation of flooring under soft tiles around the chimney pipe. At brick pipe, the width of which is more than 50 cm, a groove is made behind it (pictured). This design resembles a mini-roof. It separates the rain streams, they roll down the sides of the pipe without flowing into the under-roof space.

After installing the flooring, its geometry is checked. The length and width of the slope at the top and bottom, the height of the slope on both sides are measured, and the diagonals are measured. And the last check is plane tracking - the entire slope must lie entirely in one plane.

Soft tile roofing technology

When purchasing, you will most likely be provided with instructions, in which the installation of soft tiles will be described step by step and in detail, indicating all exact dimensions, which this particular manufacturer requires. These recommendations should be followed. However, it is worth getting acquainted with the order of work and their volumes in advance - in order to understand the intricacies of installation and required quantity materials.

Let’s say right away that you need to handle soft tiles carefully when laying them - they don’t like being bent. Therefore, try not to unnecessarily bend or wrinkle the shingles (this is one fragment consisting of a visible and mounting part).

Overhang reinforcement

The drip bar is installed first. This is an L-shaped sheet of metal coated with paint or polymer composition. Polymer coating more expensive, but also more reliable. The color is selected close to the color of the bitumen shingles.

The drip strip is installed along the roof overhangs

The purpose of the drip strip is to protect the sheathing, rafter sections and flooring from moisture. One edge of the drip is placed on the flooring, the other covers the overhang. It is fastened with galvanized (stainless steel) nails, which are driven in in a checkerboard pattern (one closer to the fold, the second almost at the edge). The fastener installation step is 20-25 cm.

The drip strip is sold in two-meter pieces. Having laid the first element, the second is fastened with an overlap of at least 3 cm. If desired, the gap can be closed: coat the joint with bitumen mastic and fill it with sealant. At the same stage, hooks are installed, or at least nailed, which will hold the gutters.

Laying a waterproofing carpet

Regardless of the angle of the roof, a waterproofing underlay must be laid in and along the slope. It is sold in rolls meter width. An adhesive composition is applied to the bottom side, covered with a protective film or paper. Before laying, the paper is removed and the valley carpet is glued to the flooring.

Installation of a waterproofing carpet begins with laying it in the valley. Roll out the material to a meter width, distributing 50 cm on both sides of the bend. Here it is advisable to avoid joints, but, if necessary, the overlap of the two canvases should be at least 15 cm. Laying proceeds from bottom to top, the junction is additionally coated with bitumen mastic, the material is pressed well.

Next, the waterproofing carpet under the flexible tiles is laid along the eaves overhang. The minimum width of a carpet on a cornice overhang is the size of the overhang itself, plus 60 cm. The bottom edge is located on top of the drip edge and can bend down a few centimeters. First, the carpet is rolled out, trimmed if necessary, then the protective film is removed from the back and glued to the backing. Additionally, they are fixed along the edges with stainless steel or galvanized nails with a large flat head (step 20-25 cm).

At the horizontal joints, the overlap of the two sheets is at least 10 cm, in the vertical direction - at least 15 cm. All joints are additionally coated with bitumen mastic, and the material is crimped.

Underlay carpet

Underlay carpet, like waterproofing, is sold in meter-wide rolls, the back side is covered with an adhesive. The installation method depends on the roof slope and the profile of the selected bitumen shingles.


When using bitumen shingles with cuts (type Jazz, Trio, Beaver Tail), regardless of the slope, the underlayment is spread over the entire surface of the roof.

Installation of underlayment often requires trimming. This is done using a sharply sharpened knife. To avoid damaging the material below when cutting, lay down a piece of plywood or OSB.

Front (end) strip

Pediment strips are mounted on the side sections of the overhangs. These are strips of metal bent in the shape of the letter “L”, along the bend line of which there is a small protrusion. They protect the laid roofing materials from wind loads and moisture. The gable strip is laid on the flooring on top of the underlay or waterproofing carpet, fixed with nails (stainless steel or galvanized) in a checkerboard pattern with a pitch of 15 cm.

These planks also come in 2 m pieces and are laid with an overlap of at least 3 cm.

Marking the slope

To make installation of soft tiles simple, markings in the form of a grid are applied to the underlayment or flooring. This is done using a paint cord. Lines along the eaves are drawn at a distance equal to 5 rows of tiles, in the vertical - every meter (the length of one shingle of flexible tiles). This marking makes installation easier - the edges are aligned using it, and it’s easier to track distances.

Valley carpet

More valley material is laid on top of the already laid waterproofing carpet. It is slightly wider and serves as an additional guarantee of no leaks. Without removing the protective film from the bottom side, it is laid, trimmed at the bottom in the overhang area, and the boundaries are marked. Stepping back from the 4-5 cm mark, a special mastic with increased fixation, Fixer, is applied. It is applied from a syringe, with a roller, then rubbed into a strip about 10 cm wide with a spatula.

The valley carpet is laid out on the mastic, the folds are smoothed out, the edges are pressed. Stepping back from the edge by 3 cm, it is fixed with nails in increments of 20 cm.

Connection to a brick pipe

To bypass pipes and ventilation outlets, cut-outs are made from valley carpet or galvanized metal painted in the appropriate color. The surface of the pipe is plastered and treated with a primer.

When using a valley carpet, a pattern is made so that the material extends onto the pipe by at least 30 cm, leaving at least 20 cm on the roof.

The pattern is coated with bitumen mastic and placed in place. The front part is installed first, then the right and left.

Some of the side elements are wrapped onto the front part. The back wall is installed last. Its parts extend to the sides.

At correct installation on the flooring around the pipe there is a platform completely covered with a valley carpet. Before laying the tiles in this place, the surface is coated with bitumen mastic.

The tiles extend onto the laid carpet on three sides, not reaching the walls of the pipe 8 cm.

The upper part of the junction is sealed using a metal strip, which is attached to dowels.

All gaps are filled with heat-resistant sealant.

Round pipe output

To pass ventilation pipes There are special pass-through devices. They are positioned so that the lower edge of the element extends onto the tiles by at least 2 cm.

Having attached the passage element to the roof, trace its internal hole. Along the applied contour, a hole is cut out in the substrate into which a round pipe is inserted.

The back part of the skirt of the passage element is coated with bitumen mastic, adjusted to the desired position, and additionally secured around the perimeter with nails. When installing soft tiles, the penetration skirt is coated with mastic.

The shingles are cut as close as possible to the protrusion of the penetration, the gap is then filled with mastic, which is covered with a special coating that protects against ultraviolet radiation.

Start strip

Installation of soft tiles begins with laying the starting strip. Usually these are ridge-eaves tiles or row tiles with cut petals. The first element is laid on one of the edges of the slope, with its edge touching the gable strip. The lower edge of the starting strip is placed on the dropper, 1.5 cm away from its fold.

Before installation, the protective film is removed from the back, the shingles are leveled and laid. Each section of bitumen shingles is fastened with four nails - in the corners of each fragment, 2-3 cm away from the edge or perforation line.

If a cut of ordinary tiles is used as a starting strip, some of it will lack adhesive. In these places, the substrate is coated with bitumen mastic.

Installation of soft ordinary tiles

There are flexible tiles with an applied adhesive mass, protected by a film, and there is a composition that does not require a protective film, although it also fixes the elements well on the roof. When using the first type of material, the film is removed immediately before installation.

Before laying bitumen shingles on the roof, open several packs - 5-6 pieces. Laying is carried out from all packs at the same time, taking one shingle from each one in turn. Otherwise, there will be obvious spots on the roof that differ in color.

The first shingle is laid so that its edge does not reach the edge of the starting strip by 1 cm. In addition adhesive composition, the tiles are also secured with roofing nails. The amount of fasteners depends on the angle of the slope:


When installing soft tiles, it is important to drive the nails in correctly. The caps should press against the shingles but not break through the surface.

Valley design

Using a painter's cord, mark a zone in the valley into which nails cannot be driven - this is 30 cm from the middle of the valley. Then mark the boundaries of the gutter. They can be from 5 to 15 cm in both directions.

The upper corner, which is turned towards the valley, is trimmed

When laying ordinary tiles, the nails are driven as close as possible to the line beyond which nails cannot be driven, and the shingles are trimmed to the floor of the gutter laying line. To prevent water from flowing under the material, the upper corner of the tile is cut diagonally, cutting off about 4-5 cm. The loose edge of the tile is smeared with bitumen mastic and fixed with nails.

Pediment decoration

On the sides of the slope, the tiles are cut so that 1 cm remains before the edge (protrusion) of the end strip. The upper corner of the shingle is cut in the same way as in the valley - an oblique piece of 4-5 cm. The edge of the tile is coated with mastic. A strip of mastic is at least 10 cm. Then it is fixed with nails, like the rest of the elements.

If the flooring in the area of ​​the ridge is made continuous, a hole is cut along the ridge, which should not reach the end of the rib 30 cm. Bituminous shingles are laid up to the beginning of the hole, after which a special ridge profile with ventilation holes.

It is fixed with long roofing nails. Several elements can be used on a long ridge; they are connected end-to-end. The installed metal ridge is covered with ridge tiles. The protective film is removed from it, then the fragment is fixed with four nails (two on each side). The installation of soft tiles on the ridge goes towards the prevailing winds, one fragment overlaps the other by 3-5 cm.

Ridge tiles are ridge-eaves divided into three parts. There is a perforation on it, and the fragment is torn off along it (first bend it, press the fold, then tear it off).

The same elements can be cut from ordinary tiles. It is divided into three parts, without paying attention to the drawing. The corners of the resulting tiles are cut off - about 2-3 cm on each side. The middle of the fragment is heated with a hair dryer on both sides, placed in the middle on a block and, gently pressing, bent.

Ribs and bends

The ribs are covered with ridge tiles. A line is drawn along the bend at the required distance with a paint cord. The edge of the tile is aligned along it. The laying of flexible tiles on the edge goes from bottom to top, each fragment is glued, then, retreating 2 cm from the top edge, it is fixed with nails - two on each side. The next fragment extends 3-5 cm onto the laid one.

Surely, you have repeatedly noticed that many private houses are covered with flexible tiles, a noble, solid and aesthetically attractive roofing material. You can also equip such a roof, because this covering can be laid on a roof of any complexity, the slope of which reaches 12 - 90 degrees. Bitumen is very light, which makes it easier to install a soft roof with your own hands. Today we will talk about how to cover a roof with soft tiles.

Calculation of bituminous shingles

Before purchasing soft tiles, you must take into account that the price of a soft roof will depend on the coverage area and the number of additional elements. A feature of the material used to organize the roof is the minimization of waste during work. It is this factor that allows you to accurately calculate the roof and calculate the required amount of base material.

Let's give an example of calculating the amount of flexible tiles. So let gable roof has the following parameters: length is 6 meters, height - 4 meters; tilt angle - 32 degrees. Then the total area is 48 square meters (4*6*2). Keep in mind that one package of flexible tiles is enough for 3 square meters. But be careful, as each package indicates the area to be covered. Then you will need 16 packs (48/3).

Similarly, you can calculate the amount of lining material and valley carpet required. It should be noted that the technology of covering a roof with soft tiles is such that there will always be cut off parts and waste. Therefore, feel free to add another 10-15% to the calculated amount. After purchasing soft tiles, you need to store them in a warm, dry, shaded place, stacking no more than 12 packages one on top of the other.

Installation of sheathing under the roof

To install asphalt shingles correctly, it is necessary to properly prepare the base. Soft roofing can be laid on ordinary sheathing, which can be lattice or solid and attached to the rafters. The frame is most often made of wood. If you need to arrange a lattice sheathing, then take boards for this.

In this case, it is advisable to use planed boards made of coniferous wood, which have a thickness of approximately 20-25 millimeters. To create a continuous sheathing, you can use moisture-resistant plywood or chipboard, tongue and groove boards and edged boards. The moisture content of the material should not be more than 20% of dry weight. The material is attached to the rafters using ordinary nails or self-tapping screws.

To increase service time wooden elements they must be impregnated with an antiseptic before installation. When creating the sheathing, calculate in advance the installation step of the rafters and the thickness of the board used for its construction. If the step is 60 centimeters, then you can use a board that is 20 millimeters thick. With a rafter pitch of 90 centimeters, a board approximately 23 millimeters thick is required.

The joints of the boards must be placed at the support locations, and the boards must have a length of at least 2 spans between the supports. When laying sheathing under a soft roof, you must remember what should be left between separate materials a couple of millimeters to compensate for the expansion of wood during drying.

On the sheathing, a gap of 1-5 millimeters is made between the boards, and between large panel elements - 1-3 millimeters. Plywood and slabs are laid on the rafters with the seams staggered. You don’t have to leave such gaps if all the wood has been previously subjected to technical drying.

Installation of the lining layer

After arranging the sheathing under the soft roof, you need to lay a lining layer, the main purpose of which is to protect the house from moisture in the event of possible leaks of flexible tiles. According to current standards, if the roof slope is 18 degrees or a little more, then waterproofing can only be installed parallel to the end and eaves edges. These areas are considered the most likely places for leaks.

Things will be different if the roof has a smaller slope angle - from 12 to 18 degrees. The technology for installing such a waterproofing layer involves laying it over the entire roof area. This layer is mounted parallel to the eaves overhang from bottom to top with an overlap of at least 10 centimeters for transverse seams and at least 15 centimeters for longitudinal seams, fixing the edges with nails at intervals of approximately 20 centimeters. The seams must be sealed with glue.

To protect the edges of the roof frame structure under soft tiles on the eaves overhangs from moisture, you need to install metal eaves strips called “droppers” on top of the underlayment with an overlap of at least 2 centimeters. They are nailed in a zigzag pattern with special roofing nails, maintaining a pitch of 100 millimeters. To protect the sheathing, pediment strips with the same overlap of 2 centimeters are mounted on the end parts. The strips are stuffed on the eaves and ends on top of the lining layer.

If the structure has elements such as valleys, then it is necessary to lay a special carpet that matches the color of the tiles on both sides. The edges should be fixed with roofing nails, maintaining an interval of 100 millimeters. After fixing it, it would not be superfluous to coat the carpet along the edge with bitumen mastic.

Ventilation space arrangement

Without sufficient ventilation in the attic, the microclimate will be disrupted, humidity will increase and condensation will form. Ventilation is ensured thanks to three elements: channels above the thermal insulation, a hole that serves for the flow of outside air and exhaust holes that are located in the upper part of the roof.
If the eaves in a residential building are lined with siding, then the soffit strips will act as a ventilation gap.

If, when installing a roof under a soft roof, the cornice is decorated with clapboard, then it is customary to create a gap between the boards. Ventilation of a roof made of flexible tiles is achieved through a ridge, which is usually laid on a special ribbed profile. But often its capacity is not enough and it is necessary to install special ventilation elements on the roof surface.

If the roof slope is 15 - 40 degrees, then the area of ​​the ventilation space is calculated as the quotient of the total area of ​​the slopes and a coefficient of 300. And if the slope reaches 41 - 85 degrees, then it is calculated as the quotient of the soft roof area and a coefficient of 600. Let the total roof area be 50 square meters, the angle of inclination is 35 degrees, and the cross-section of the ventilation element is 258 square centimeters.

The ventilation area in this case will be 0.167 square meters (50/300) or 1670 square centimeters. Then the required number of ventilation elements is five (1670/258). The number of ventilation elements that are installed on the ridge is half the number on the roof slopes, that is, 3.

Installation of soft tiles

Manufacturers of flexible tiles do not recommend installing them at temperatures below plus 5 degrees, because shingles become brittle in the cold and the procedure for installing a roof with soft tiles becomes difficult, and the lack of heat affects the tightness of the joints. In winter, the joints and bends of shingles should be heated with a hair dryer or other device that generates a heat flow. To lay the material on the roof in the summer, it must be taken in parts, because the protective film from the tiles heated by the sun is difficult to remove.

When laying tiles, roofers often make the same mistake, as a result of which the roof has a different shade in different places. Remember that tiles in different packages may not be from the same batch, but from different ones, which is why their color differs. Thus, it is necessary to use several packages of material at once so that the color of the roof is uniform.

To simplify the work and ensure straight lines, before covering the roof with soft tiles, chalk markings of the slope along the sheathing and lining are carried out on the roof. Horizontal lines are drawn parallel to the eaves overhang in increments of 80 centimeters. This makes approximately 5 rows of tiles. Vertical lines are drawn along the length of the slope in increments of 1 meter.

Installation of a roof made of flexible tiles begins with the arrangement of a zero “eaves” row. Self-adhesive ridge-and-eaves tiles are glued end-to-end over the metal strip. You need to retreat 1-2 centimeters from the edge of the slope. The tiles on the other side are nailed, and the first row of ordinary flexible tiles is laid on top of the fastening point. If you did not buy ridge-eave shingles, you can attach simple shingles to the eaves, but without tabs.

The first row of ordinary flexible tiles begins to be laid from the center of the eaves, heading towards the ridge and gables. To move on the roof in hot weather, you need to use special manholes, otherwise they may remain on the roof. roofing shoe marks. First, remove the protective film from the back side of individual roofing tiles and glue them to the base. The tiles also require additional fastening.

The tiles are secured with nails, driving them in when laying two adjacent rows. When you hammer a nail into the first row, you will nail the second one at the same time. You cannot move the fastening - drive the nail from the very edge or into the center of the petals, since the structure of the roof made of soft tiles does not allow for chaotic fastening, you cannot recess the nail too much - the head must be located on the same level with the roofing.

Approximately 4-5 nails are used per shingle. This will be enough, since the bitumen tiles will stick together to each other under the influence of solar heat and stick to the sheathing. The length of the nails is selected according to the type and thickness of the sheathing. The diameter of the nail should be approximately 3.2 millimeters, the diameter of the head should be 10 millimeters.

When installing subsequent rows of tiles, remember that the lower petals of the material must correspond to the upper ones, which are located on the already nailed row. Along with this, it is customary to shift the petal by half to the left or right.

Ridge tiles are obtained by dividing the eaves tiles into three parts at the perforation points. Mount ridge tiles to the ridge of the roof, having previously cut the tiles, with the short side parallel to the ridge. Nail with four nails so that the nails are located under the overlapping shingles with an overlap of 5 centimeters.

Correct design of junctions

In the process of installing a soft covering for a roof, quite often you have to deal with certain difficulties and various objects to which the roof adjoins. For example, the most basic item of this type is a stove heating pipe. In the area where the pipe adjoins the roof, a gap always forms through which moisture flows.

To get rid of this drawback, you need to properly attach the flexible tiles. To begin, hammer the batten into the corner between the roof surface and the chimney. It is desirable that it has a triangular shape, like an ordinary wooden baseboard. Next, it is recommended to place the tiles on this strip and directly on the pipe. After this, you should lay the valley carpet on top of it, starting from the chimney.

It should cover the entire channel at a height of 30 centimeters from the roof surface. After this, the lower part of the pipe with carpet and bitumen shingles is placed in a metal apron - covered on all sides with sheets of painted tin. To avoid accumulation of snow behind the pipe, it is necessary to create a groove by installing a pyramid with two edges close to the pipe. Thus, both snow and rainwater will fall on the slopes of the gutter and flow down the roof, flowing around the pipe.

Sometimes some communications need to be routed through the roof. In such cases, it is best to use passage elements that are made specifically for tiles. They are attached to the base of the roof using nails. Such elements reliably protect the roof from leaks. For example, small-diameter antenna passages through the roof can be made with rubber seals.

Procedure for sealing joints

A special sealant is used to seal roofs made of soft tiles, overlaps of underlay carpet and ordinary bituminous tiles onto the valley carpet, passages of the ventilation system and various junctions. Immediately before applying the composition, clean the surface of bulk materials, oil and dirt. On dusty and porous substrates, first apply a bitumen solution. Remember that if there is excess glue, excessive dissolution of the bitumen may occur.

The composition is applied to one of the surfaces to be glued with a spatula. Maintain a layer thickness of 0.5 - 1 millimeter. The width of the sizing is indicated in the instructions. When gluing connections to pipes and walls, apply sealant over the entire contact surface. Grout the masonry joints with mortar flush with the brick. The gluing process lasts 1-3 minutes, depending on the air temperature. At low temperatures The composition must be heated before application.

Now you know how to cover a roof with soft tiles! In addition, you can always renew the roof with flexible tiles without removing the old covering. Laying new soft shingles over old ones is not much different than installing from scratch. To do this, you need to lay it on the protruding cornice strip turn the shingle upside down and glue it, and trim the protruding part along the eaves. Next, the tiles are laid exactly on top of the previous pattern.

Private construction and the use of soft roofing is a fairly relevant topic. This material has a lot of advantages. Among them are light weight, absolute tightness, visual appeal, the ability to be used on a wide variety of roof shapes, long useful life and low cost of soft roofing. Moreover, the rain does not drum on such a roof, but rustles quietly. In addition to high performance and technical characteristics, the material allows you to install a soft roof yourself, without involving specialists in the work.

The concept of a soft roof

Soft roofing is a modern material, the base of which is fiberglass sheets impregnated on both sides with rubber bitumen. Rubber bitumen is highly airtight and moisture resistant, which is why soft roofing has become so widespread in the construction of buildings. Also, soft roofing contains a special coating that increases wear resistance and prevents the roll covering from sticking together.

Soft roofing is considered an ideal covering for roofs with a slope angle of at least 11 degrees. Therefore, when choosing a material for such strict requirements, be careful. Soft roofing is often called bitumen shingles, which are used as upper layer The roofing pie differs from other materials in its structure, which resembles rolled materials.

Styling tools

Flexible roofing can be laid by 1 person. The only requirement for the roof surface, which we have already mentioned, is a slope of no more than 11º. But the maximum slope angle is not limited. Laying a soft roof with your own hands requires the following materials and tools: a hammer, a knife, mastic, sealant, a mastic trowel, roofing nails, eaves and end strips, waterproofing carpet, ridge-eaves strip and work gloves.

Ventilation device

The ventilation system is able to provide air circulation, which is necessary to prevent condensation from occurring on the lower part of the base. Neglecting this stage when laying soft roofing on the roof will cause the rafter system to begin to rot, and ice and icicles will form in winter.

Components of the system roof ventilation ventilation ducts and outlets protrude, gaps between the waterproofing and the base (minimum 5 millimeters). Natural ventilation can be provided by ventilation holes that are distributed evenly under the eaves.

Lining layer

Cornice strips are made of metal and attached to the overhangs of the cornices on a lining. They are required to protect the edges of the sheathing. Gable strips are also made of metal; they are attached to the ends of the roof to protect the edges of the sheathing. The valley carpet provides additional protection of the roof from precipitation. Choose it according to the color of the flexible tiles.

In places where leaks are most likely, you need to create a lining layer: on valleys, roof ends and eaves. A special feature of the installation is compliance with the direction (bottom to top) and overlap: in longitudinal direction 150 millimeters, transversely - 100 millimeters. It is customary to coat the overlap areas with bitumen mastic.

It is customary to reinforce the valleys and ridges by 500 and 250 millimeters, respectively. In this case, the valleys must be equipped with a lining layer on both sides, and along the ends and eaves overhangs it should be laid to a width of at least 400 millimeters.

The lining is nailed to the base with galvanized roofing nails every 200 millimeters. The underlay not only protects the roof from moisture, but also from destruction if the installation of the soft roof is suspended.

Preparatory work

The base to which you will attach the soft roof must be solid. This is precisely why the process of installing a roof made of soft tiles differs from roofs for which other materials are used. For example, metal tiles must be laid on a sheathing in which a gap is allowed between the beams, which is explained by the high rigidity of the metal tiles. A soft roof does not possess these qualities and therefore requires preliminary installation of a solid foundation.

For arranging the base, you can use oriented strand board, moisture-resistant plywood with a thickness of 9 millimeters or more, as well as tongue and groove or edged boards. If you have chosen a board as the base, it is recommended to first keep it in a stack until an equilibrium moisture level is reached.

Buy material in winter and use in summer. The width of the boards is no more than 100 millimeters. It is desirable that the material has the same thickness and is sawn to band saw. The maximum moisture content of wood is 20%.

The video about the technology of laying soft roofs shows that such materials need to be laid with the seams shifted - staggered, leaving a gap of 1 centimeter between them. The surface must be dry, clean and smooth. The quality of installation and service life of the soft roof will depend on these conditions.

The roofing pie must necessarily have the following layers: a waterproofing layer laid on the rafters; mineral wool insulation if you are planning to install an attic; waterproofing roofing carpet laid overlapping on the base from the outside.

Subtleties of installing a soft roof

To cover a roof with a soft roof with your own hands, in addition to having free time, you also need good weather. It is customary to carry out work in warm, dry weather, and the air temperature should not fall below plus 5 Celsius. If, due to necessity, it is necessary to lay a soft roof in winter at an inopportune time, the tiles must be kept in a building at room temperature before starting work. You can also use a hot air burner.

The choice of this temperature regime is explained by the characteristics of the shingle - a sheet consisting of 3-4 “tiles”. It can be attached to the surface with nails or using a self-adhesive layer located on the inside. The tightness of the tiles is ensured by the heat of the sun; under its influence, the sheets are soldered to the base and to each other. This does not happen when sub-zero temperatures, and high-quality insulation does not work.

Soft tiles should be used simultaneously from 5-6 packages and selected one element at a time to avoid sharp differences in shades in case it is necessary to repair the soft roof with elements from another package. It is this property that constitutes another advantage of this material: a slight difference in shades facilitates the process of replacing tiles and decorates its matte surface.

Choice of mastic

To lay the top layer of a soft roof, you should use a bitumen-polymer material, which allows you to create a continuous elastic coating that can withstand temperature and mechanical deformations of the base. According to the technology of laying soft roofing, it is recommended to use cold and hot mastics to attach rolled material to the roof.

Cold mastics are traditionally used for the internal layers of the roof, and the hot substance is used as an external coating. Cold mastics include roofing felt and bitumen, and hot mastics include tar and roofing felt. The mastic used must contain bitumen and a pulverized mixture or fiber filler. Among the dusty materials are lime, gypsum and ash.

Production of bitumen mastic

you can buy bitumen mastic, but you can do it yourself. To do this, take bitumen, which is close to 80% of mastic, and filler. By taking 2 portions of bitumen and diesel fuel per 1 portion of filler, you will get a cold mixture. The bitumen needs to be heated to 180 degrees while diesel fuel and filler are being prepared elsewhere. Both boilers can be mixed only after the water has evaporated in the bitumen.

To make hot mastic you need to use a boiler. The bitumen in it should be heated to 200 degrees, and filler should be added slowly. It is important that during the procedure the temperature does not drop below 160 degrees.

To check the quality of the mastic, you need to lay it at an angle of 45 degrees, after preheating the mastic to 60 degrees. The video about laying a soft roof shows: if the coating drains, then its quality is poor. If it does not drain, then you should let it dry. When drying out quality material cracks will not appear.

Laying a soft roof

Before directly laying the roof, run a solution of bitumen and diesel fuel over the wood surface. Then slowly coat with mastic, then lay down glassine and roofing felt. It is customary to start installation from the middle part of the cornice and move towards the ends to the right and left. On the underside of soft tiles, before applying, you need to remove the film that protects the glue.

If you use cold mastic, then you need to wait 12 hours after applying a layer, only then can you apply a new layer. When covering with hot mastic, you can apply layers one after another. Each roofing element must be nailed in the amount of 4-6 pieces.

When laying rolls according to the instructions for laying soft roofing, make a 7-10 cm overlap. In all cases, it is recommended to follow the overlap rule: place each top row so that the fastening joints of the previous one are covered. The next new layer is shifted depending on their number (with 2 layers - by half, and with 3 - by a third).

Along the edges of the roof, trim off the excess and glue with mastic. Thanks to the properties of modern soft roofing materials, the useful life of the roof covering is about 30 years. But this does not mean that you can forget about preventive measures.

Installation near ventilation pipes

Proper insulation of joints and careful fastening of material require space around antennas and pipes. Installation of a soft roof here is easy provided that passage elements are used. Without such components, the tightness of the coating is compromised. Even before laying the bitumen shingles, you need to outline the places where you will install ventilation and pipes.

Then you need to cut holes around which the edges of the lining carpet will be glued with mastic. Spread the top surface of the carpet along the contours of the elements that need to be glued and nailed. Place the tiles on top of the mastic.

It is recommended to treat the joints between the upper part of the passage element and the bitumen shingles with sealant. Having completed the work to the ridge line, you need to use special ridge elements of flexible tiles, which are bent over it, glued to mastic and nailed.

Soft roof repair

Frequency repair work What needs to be done with the roof of the house depends directly on the base on which you installed the tiles, and on the cost of laying a soft roof. Wooden lumber, cement and concrete screed - they all react differently to soft roofing, which causes some damage.

Cleaning the damaged area

Immediately before starting repairs, determine whether such work is needed at all and to what extent. To do this, assess the extent of the damage present. If holes have formed in the rolled covering, it is recommended to fill them with mastic, observing the sequence of materials used for this.

Roll roofing repairs should be carried out exclusively in a clean area. And this is very problematic, because roofing material there is a special sprinkle. For this reason, it is necessary to thoroughly clean the area where repair work will be carried out.

Crumbs can be removed by using process oil. Anthracene oil is best suited for cleaning roofing felt, while solar oil is used for roofing felt. Clean with a regular rag or brush. With this treatment, you can remove the coating and soften the surface for further repairs.

Repair work

After preparing the damaged area, you can proceed to the main work. For small defects, you can use regular mastic with a patch. But this solution is not suitable if all roofing layers are broken.

If several layers of the roof are damaged at the same time, it is recommended to clean the area from the old layer of mastic and dirt, and then dry it. After this, you need to prepare a mastic mixture with the addition of sawdust or sand. This mixture should be used to fill all existing damage so as to even out the edges. The mastic should extend at least 10 centimeters on all sides of the patch.

Using hard brushes and brushes, mastic can be applied in the most hard to reach places. If you are working on small area, then it is advisable to use a simple spatula, which allows you to apply thick mastic and mass with sawdust. If a “water bubble” occurs in the roof, repairs must be carried out in the same way as in a situation with a regular hole. The main thing is to determine in time the source where the water comes from.

If cracks appear in the roofing material, it should be cut to the bottom layer. Then clean off excess mastic and debris, after which the area is dried and filled with new mastic. You can do without a cut if the cracks are small. They should be covered with a patch and mastic. If small cracks appear throughout the entire area of ​​the soft roof, it must be prepared and covered with heated mastic.

Restoration of sprinkles

After repairing the soft roof, it is necessary to replace the removed layer of topping in place to avoid unnecessary heating of the material and melting of the mastic. To do this, smooth the surface and cover the roof with sand. Excess coating that does not adhere to the roof will be removed on its own over time. However, if you want, you can remove it yourself.

Now you have learned what advantages a soft roof has - tightness, long service life and a reasonable price for laying a soft roof. Follow our instructions carefully to install flexible tiles correctly. Use the recommendations regarding the choice of mastic and its preparation.
