Flat roofs are used not only in residential buildings, but also in buildings for auxiliary and utility purposes. A garage with a flat roof can be not only practical and functional, but also an original structure. A flat roof is ideal for regions with low average monthly rainfall. However, even in areas with a lot of precipitation and snowy winters, the installation of a flat roof is possible, provided that the load-bearing frame of the roof is strengthened and the permissible loads on the floor system are taken into account.

Flat roofing has the following advantages:

1. The building with a flat roof looks quite original and modern.
2. On such a roof you can arrange a terrace, a recreation area, or use it according to the preferences of the owners.
3. Since this design does not require a complex and expensive device rafter system, and also due to the small coverage area, garage owners receive significant savings on the construction of this part of the structure.
4. If you compare a flat roof with pitched structures, then its repair is much simpler and does not require much time from you.

The only drawback of such roofs is the need for careful design and calculations future design taking into account the maximum permissible loads and types of roofing. If mistakes are made at this stage, the roof may not only leak, but will also not be able to withstand the weight of the snow cap and ice.

Attention! When designing flat roofs a slight slope of the surface is laid for the drainage of melt and rainwater. This slope should be within 4°.

Types of flat roofs

Reinforced concrete floor slabs or metal profile beams can be used as the base of a flat roof. Structure roofing pie and the sequence of its implementation are directly related to the type of base used.

All flat roofs are divided into several subtypes depending on the method of forming the roofing pie:

• monolithic roofs in classic design;
• structures made of corrugated sheets;
• inversion coatings, which can be classified as special option traditional roofing.

All of the above structures are divided into non-exploitable and exploitable depending on the strength and bearing capacity grounds.

Monolithic roofs

Monolithic roof structures for garages are considered classics. They belong to the category of soft roofs. The roofing pie of such a roof consists of the following layers, located from bottom to top:

1. The base is a reinforced concrete slab for arranging floors.
2. A film vapor barrier is laid on top of it.
3. Next comes the layer thermal insulation material. Typically, mineral wool is used for these purposes.
4. A waterproofing roofing carpet is laid over the insulation. Rolled material containing bitumen is used as waterproofing.
5. If the roof is serviceable, then a reinforced concrete screed is made. To strengthen it, it is used metal grid. After this, if necessary, an additional layer of waterproofing and a tile covering can be laid.

Sometimes, to equip a flat monolithic roof, metal I-beams with a height of 120-150 mm are used. The design then proceeds as follows:

1. Mounted on the lower flanges of these beams continuous lathing from wooden planks 2.5 cm thick, which are covered with roofing felt.
2. After this, the reinforcing mesh is laid so that it is at a distance of 30-50 mm from the roofing material.
3. Then the space between the beams is filled with concrete mixture.
4. When the solution has set, a classic soft roll roof is installed.

Quite often, flat garage roofs are made from load-bearing corrugated sheet metal. This is the most economical option arrangement of a flat roof structure. But this option is only suitable for unused roofs. The design of the roofing pie in this case is practically no different from that described above, with the only difference being that an additional layer of heat insulation is required.

Classic design

Such a structure in cross-section looks like a multilayer structure, which must contain the following mandatory layers:

• flat base (concrete, metal beams or load-bearing profiled sheet);
• vapor barrier layer;
• layer of thermal insulation material;
• waterproofing carpet.

Typically used as a vapor barrier polyethylene film. It reliably protects the roof structure from warm air vapors rising from the room and causing condensation to form in the thermal insulation layer.

The following materials can be used as insulation:

• expanded clay-gravel mixture;
• mineral wool slabs;
• polystyrene foam board insulation.

The waterproofing carpet is made from roll materials produced on the basis of bitumen. You can also use sprayed membranes and special mastics for this.

Inversion roofs

The design of an inversion roof is fundamentally different from the options discussed above. In cross-section, such a roofing pie has the following layers:

1. The base is a flat concrete slab.
2. A waterproofing roofing carpet is attached to it using a bitumen primer.
3. Next, a slab of rigid thermal insulation material is laid.
4. This is followed by a drainage layer and a reinforced coating.
5. After this, geotextiles are laid, which protect the insulation from negative impact external factors.
6. The final layer of an inversion roof can be any material suitable for these purposes, for example, paving slabs, fertile layer with grass.

Important! An inversion roof can withstand significant loads, so it can be used as a serviceable roof.

General device rules

According to SNiP requirements flat roof should be performed with a minimum slope in one direction to avoid accumulation of sediment on the coating and leakage. It is worth remembering that even a minimal amount of moisture retained on the coating can lead to rapid deterioration of the roofing pie structures. This happens because due to repeated thawing and freezing of moisture, structures are deformed and destroyed.

To form the required angle of inclination, either load-bearing elements(beams or floor slabs), which are mounted in accordance with the required slope, or a special slope is made of expanded clay.

It is also worth remembering that between the insulation and the layer of deflection from bulk material There must be a separating layer. The soft roofing covering is laid in two layers with overlapping strips. In this case, the direction of laying the strips in two layers should be mutually perpendicular.

For the garage, it has gained popularity among car owners due to its simplicity and efficiency. Creating a pitched roof requires modest skills and inexpensive materials. But at the same time, the design will be durable and will reliably serve you for a long time.

Another great advantage is the short installation time. All this makes the single-pitch the optimal solution for.

How to do garage roof with your own hands? The most important thing in the device one pitched roof The garage will have a rafter system with its own hands. It receives and distributes most of the weight, transfers it to Mauerlat.

Lathing is no less important. The battens will serve as support for the roofing fastenings. The final element is the outer layer, itself roof covering. In addition, we must not forget about waterproofing and thermal insulation.

For garage with flat roof Manufacturers offer a wide range of roofing materials:

1. Slate– has good appearance, it is relatively easy to install. Service life is 35-40 years;
2. Roof tiles– best suited for creating roofs on medium/large garages;
3. Corrugated sheet– low price, fairly reliable option;
4. Soft materials – Rolled building materials are low cost. The service life of modern materials is 30-40 years. Roofing felt is much shorter – 10-15 years.

The angle of a flat roof for a garage depends on several factors. First - material type. Roofing felt has the most low angle tilt - 5-10 degrees. Slate and tiles have more - 20 and 30 degrees, respectively.

The second factor is climate. To determine the required angle of inclination, you need to know the average wind force and the amount of precipitation. For example, if the garage will be exposed to strong winds, the roof should be made with a smaller angle, more flat.

Please note that the angle and strength of the structure are in inverse relationship. It will be necessary to compensate for the loss of strength with special supports and other structural solutions.

How to make a garage roof? We need to start with calculation. In practical terms, the angle of inclination will show the difference in the height of the walls. That is, how much higher one wall of the building is than the other. For a regular, single garage, a difference of 40-60 centimeters is suitable. The roof will be strong and reliable. To make calculations, trigonometric equations are used.

Height difference:

РВ = ДС x tgA, Where

RV– Height difference;

DS– responsible for the length of the garage wall;

tan A– tangent of angle A, angle A is the angle of inclination of the roof that you have outlined for yourself.

Rafter leg:

CH = РВ x sin A, Where

CH– rafter leg size;

sin A– sine of the roof inclination angle;

RV– height difference, it is obtained from the previous formula.

You can use special programs and calculators for calculations; you don’t have to do everything manually.

Installation

Do-it-yourself pitched roof for a garage - step by step:

Slate

How to make a roof for a garage? Styling slate you need to start from the bottom. The material is laid in rows, the top sheets are placed on the bottom sheets, and partially cover them. If four slate sheets intersect in one place, special nails are used for fastening. At the edge of the roof, the roofing material is nailed down with a pair of nails.

To reduce the influence of wind, use wind board. It is laid on the rafters; the board will provide some protection from strong gusts of wind. The advantage of slate is its low price and durability (30-40 years). The tilt angle is 20 degrees.

Corrugated sheet

How to make a pitched garage roof? By using corrugated sheets- inexpensive roofing material. The tilt angle is 20-40 degrees. But an angle greater than 25-30 degrees must be chosen reasonably, as the strength of the structure will suffer. The basis for such a decision may be heavy precipitation (especially snow) in your region.

Laying the material begins with bottom corner. We must not forget about leveling the corrugated board; the cornice strip will serve as a guide for this.

It is necessary to strictly adhere to the selected overlap size. The size directly depends on the angle of the roof. The larger the angle, the less overlap will be needed.

When roofing attached garage, sheets from corrugated sheets fastened with self-tapping screws. Special attention should be given to the end of the structure. In this section, self-tapping screws are attached to all beams. Do not skimp on self-tapping screws, use a standard quantity, otherwise you will suffer reliability roofs.

For installation you will need a simple tool - a power saw, electric drill, screwdriver.

Do-it-yourself garage with a pitched roof:

Soft roof

This includes many building materials. Soft materials are not laid at a large angle, maximum 10-15 degrees. The cheapest and most common is roofing felt.

How to properly install a roof on a garage? To begin installation, you need to prepare the roof, clean its surface of debris, and let it dry thoroughly. You need to prepare yourself roofing felt– a couple of days before the start of work, they open it and let it rest. Then a primer is applied to the roof, which will remove cracks and gaps.

After this, they apply to the rolls mastic(cold or hot). Rolls of roofing felt should be laid overlapping, in layers. Upper layer must have a protective coating. The protruding edges are folded in and secured with nails.

Modern roll materials have an increased service life and improved characteristics, but the installation process is generally similar to roofing felt.

Conclusion

How to build a roof on a garage? The first step in building a pitched roof is to create Mauerlat. Mauerlat distributes the weight from the roof to the walls of the garage. Then they move on to the rafter system.

The protrusion of the beams should be approx. 30-40 centimeters. The ends will protect the garage from precipitation getting into interior space. The laying step is 70-80 centimeters. Next step will sheathing.

Lathing for soft, rolled materials should be solid. This is not necessary for slate and corrugated sheets. The sheathing is attached perpendicular to the rafters. After this you need to do waterproofing battens.

Good for waterproofing roofing felt. It's cheap and easy to install. Instead of roofing felt, you can use film; it is laid in the same way. Then the outer layer of the roof is laid.

Homeowners have many questions when they plan home improvement DIY garage roof. Let's go through all the stages of arrangement step by step, paying attention to the main thing.

In this article

Choosing the type of roof

The first thing you need to decide on at the project stage is the type of roof: flat, pitched or gable.

Flat roofs are made of concrete. To lay concrete plates ceilings, you will need a crane installation, a crane operator and a team of experienced installers. To fill the floor with concrete mortar, you need formwork, reinforcement, a large supply of concrete and, again, people. It is clear that in the case where a flat roof for a garage is required, the best solution would be to hire a qualified team.

For this reason, we will talk about single-pitched and two pitched roofs, available for self-installation.

To choose one of the two options, you need to consider the advantages and disadvantages of each type of roof:

• A shed roof for a garage will be cheaper in terms of materials costs;
• Installation of a lean-to structure is simpler;
• This kind of work can be done faster;
• Even one person can install a pitched roof;

But if the solidity of the roof is more important, and the roof is supposed to be actively used for storage or living, then the gable roof option is preferable:

• The snow load on a gable roof is less. With the correct slope of the roof, snow does not linger on it;
• It is possible to create additional space in the attic;
• The room is better ventilated, so it is easier to perform thermal insulation;
• Less risks with varied wind loads;
• A gable roof looks more presentable

In the case of a garage adjacent to a building, to ensure the removal of precipitation, only a pitched garage roof can be built. This version is good because it will save a significant amount of money on materials and time for building walls.

It is important to decide on the type of roof first initial stage because for a gable roof the walls will be the same height, but for a single-pitch roof they will be different.

Determining the angle of the roof slope

The optimal angle of inclination of a pitched garage roof is 25-300. If you make it higher, the top will be disproportionate to the entire building. You should not make it less than 100, because... The pressure of the snow masses at this slope is critical. The range for a gable roof is much wider. In areas of heavy snowfall, the angle of inclination is 450. In general, than stronger than the wind in the region, the smaller the slope you need to choose. Conversely, the calmer the weather and more precipitation, the steeper the roof angle.

The height of the slope is also affected by the choice of roofing material. When using rolled roofing materials, the slope angle can be 100. For slate - 200. And for tiled roofing - at least 300.

It is important to decide on the type and material of the roof before starting construction also because the size and type of foundation will depend on this: a slab under the entire garage, strip or columnar.

Roofing materials

• Ruberoid. Inexpensive soft roofing material. Service life up to 5 years (modern analogues have 15 years). Not suitable for extremely hot or cold climates. Sold in rolls. Easy transportation and installation. It is laid in several layers. Sticks together bitumen mastic. In this case, waterproofing the garage roof will not be required. Please note additional expenses for mastic, because its average consumption is 0.8 kg per 1m2
• Slate is an inexpensive, stronger and more durable material than roofing felt (can last about 10 years). Sold in sheets. Installation is relatively simple. Cons: heavy, difficult to change due to fragility. Suitable for garage roof roofing from 300
• Metal tiles and corrugated sheets. Modern durable lightweight materials based on galvanized profiled sheets. Top coated with polymer protective coating. Easy installation. Suitable for slope angles from 150. Durable. Withstands a wide temperature range. Wide decorative possibilities. Require high-quality fastening special hardware and caution during installation. Damaged polymer coating urgently needs to be repaired in order to preserve it protective functions. Low sound insulation. Relatively expensive for the price.

To calculate the consumption of roofing material, you need to know the length and width of the garage, and the width of the roof overhang (from 20 to 40 cm, depending on the vulnerability of the wall material). Calculation of the area for a pitched roof: multiply the numerical values ​​of the width and length of the garage (with overhangs) and divide by the cosine of the slope angle. For the gable version, in the same way, you need to calculate the area of ​​​​each slope, and then add the resulting values. Next, the roof area is divided by the area of ​​the sheet of roofing material. This results in the required number of sheets. You should also take into account the margin for possible defects.

Choosing a rafter system

Exists whole line methods for constructing pitched roofs. For example, methods with or without floor beams. Methods when rafters are laid on top of opposite walls with a height difference. A method where roof trusses are pre-installed on the ground, including floor beams, slope height posts and rafters. Especially important to select a rafter system, have the dimensions of the garage.

The same applies to gable options. For the layered technique, a strong frame is first mounted, resting on the centers of opposite walls, and then the upper ends of a pair of rafters are placed on it. There is also different versions with gable trusses: with and without central support. Finally, the ancient technique of laying roofs on slabs.

To find out which roof design is suitable in this case, you will have to familiarize yourself with the relevant teaching materials. By selecting a certain design, you must carefully study the step-by-step instructions. Determine at what stages you may need help.

Let's calculate the consumption of materials

After choosing a rafter system, you need to calculate the length and thickness of the material for it. This is the most important part of creating a rafter system. To do this you need to know:

Roof drop height. It is calculated by the formula: the length of the wall (along which the slope will run) multiplied by the tangent of the angle of inclination.

The length of the rafters is calculated using the formula of the Pythagorean theorem:

The numerical value of the squared length of the rafters is equal to the sum of the squares of the length of the wall and the height of the drop. To the resulting length of the rafters you need to add the length of the roof overhang.

The pitch of the rafters is calculated individually and ranges from 1 m to 60 cm, depending on the load on the roof.

The cross section of the rafters is calculated using a formula that takes into account many factors from specific gravity roofing materials to wind loads in a given region. Therefore, for such complex calculations it is better to use an online calculator.

The cross-section of the Mauerlat beams and the ceiling, if they are needed, is taken from 100 x 50 mm. The distance between the ceiling beams is approximately 1 m. Anchoring is used for them

What other tools and materials will be needed to install the roof:

• Axe, hacksaw, hammer.
• Construction stapler with staples, level, tape measure, marker, screwdriver.
• Unedged board 25x150 mm, taking into account the fact that for each sheet of roofing material there must be at least 3 boards.
• Bar 50*50 mm for counter-lattice.
• Vapor and waterproofing is a membrane that, on the one hand, acts as a waterproofing for the roof of a garage, and on the other, it allows steam to pass from the room to the street. Such a film should be suitable for gluing with special mastic or special tape.
• Insulation (if the room is capital, then roof insulation will be required).
• Metal corner fasteners for beams, nails, screws.
• Mastic for gluing vapor and waterproofing.

Installation of a pitched roof

It is important to orient the slope of the roof towards the windy side so that the air flow does not lift up, but presses the roof.

• Installation begins with the installation of a mauerlat - lining the garage walls from dry, impregnated antifungal composition wooden beams. It is carefully aligned horizontally. Fixed in the wall with long anchor bolts
• The selected roof rafter system is mounted on the Mauerlat. To fasten the rafters, 100 mm nails or anchors are used. All fastening points are treated with a bioprotective compound.
• Garage roof waterproofing is laid on the rafters with an overlapping layer of about 20 cm. It is secured with a stapler. The membrane overlaps are connected and glued with mastic or tape.
• Installation of counter-lattice made of bars. Allows you to create a ventilated gap under the roof.
• Laying sheathing from boards with a frequency depending on the roofing material.
• Installation of roofing. Starts from the bottom corner of the roof. The first sheet is placed level. The following are oriented from it. In general it is necessary to follow step by step instructions for laying specific roofing material.
• The insulation of the roof occurs in the intervals between the rafters or is placed in the spaces between the ceiling beams.

The installation of a gable roof follows the same plan, only the rafter triangles will be isosceles. Let's look at the option of installing a gable rafter system.

Simple gable roof design

Material for beams, rafters, struts - 50x150 mm board, for ridge girder - 50x200 mm board. For puffs - a board 25x10 mm.

• We mark on the garage according to long sides strapping equal lengths (from 60 to 40 cm). We mark symmetrically from external corner boxes, from where the outer rafters will be attached.
• Lay according to the marks ceiling beams on the edge. They are located strictly horizontally, check with a level.
• Secure with nails or self-tapping screws. In this version, the ceiling beams also play the role of ties that compensate for the expansion.
• Place boards or plywood on the beams to provide access for further installation.
• Mark the centers of the end walls. In these places we temporarily nail the slats vertically, one side of which coincides with the imaginary axis of symmetry. Using these slats, pulling a cord between them at the required height, we determine the position of the skate.
• Having attached the board to the location of the outer rafter, we mark the resulting cutting lines of the board. The template is ready. We cook according to it required amount rafters
• Regarding the temporary slats, after about 1.5 meters we attach the support posts for the ridge girder. Checking the vertical. We fasten it with a corner metal tie.
• We lay the ridge girder board edgewise on the supports. Check the horizontal position and secure it with nails or
• At the bottom, parallel to the girder, we nail bars to the base of the central supports, which will act as a plank.
• We install a strut in the center of the roof with a slope of 450. Its top rests on the shoulder strap, the bottom on the block at the base of the supports. We install a paired strut symmetrically on the other side of the support.
• We install the rafters. We start with the outer pairs, stretching the lace between them. We fasten it with nails or self-tapping screws to the trim and to the ceiling beam.
• We strengthen the outer rafters with additional vertical posts attached to the frame below.
• Each pair of rafters is additionally secured with a tie.

It would be useful to install an exhaust pipe in the garage. Its diameter must be at least 100 mm, length at least 50 cm. It can extend both into the wall and into the roof. It would be good if it was equipped with a special valve to preserve heat in the garage.

A convenient option for an outbuilding would be to combine a garage and a bathhouse under one roof. In this case, a full-fledged attic can be organized in the under-roof space.

Car enthusiasts with extensive experience know very well that a perfectly made roof for a garage is very important, since it is not only the final stage of the entire construction, but also serves as protection from various atmospheric precipitations. Roofing is difficult process, therefore, you must first become familiar with what kind of roofs are made on garages and choose the right roofing covering.

What types of garage roofs are there?

The roof for a garage can be varied, so you must initially decide on its design. In many cases, it is possible to replace one type of roof with another, but this involves additional expense and worry. That’s why it’s better to do it at the initial stage of roof construction right choice.

Before choosing one of the types of roof frames, you should decide on its load-bearing characteristics, the size and shape of the box, and then consider one of the presented roof design options.

Features of a pitched roof device

A pitched roof is the simplest type of structure, which is in great demand today, since it has no analogues of similar cost. To equip such a roof, you do not need to use special building materials, special equipment or have deep knowledge in the field of design.

A shed roof is the simplest and cheapest structure for covering a garage.

Features of the construction of a pitched roof are as follows:

Two boards connected along the wide side are often used as rafter legs, however the best option- use beams made of metal or wood with a cross section of 50*150 mm.

A pitched roof consists of the following parts:

• the base of the roof is the rafter system to which all other constituent elements are attached;
• sheathing is a support for the roof covering;
• elements that strengthen the rafter system;
• insulating materials that protect the structure from water and retain heat inside the structure;
• directly covering the garage roof.

The upper ends of the garage with a pitched roof must have a mauerlat or logs that support the rafters. They are attached to the walls using wire anchors. The anchors themselves can be embedded in the masonry or driven into the wall.

Such a structure can be covered with any type of roofing material: roofing felt, corrugated sheets, soft tiles etc.

How is a gable roof constructed?

A gable roof is installed over the garage if an attic is needed. The most common gable roof gable design is an isosceles triangle.

The rafter system of a gable roof can be made in the following options:

Installing a gable roof is very simple, since its base consists of several rafters of identical sizes. The installation of the frame rafters is done sequentially, and then they are connected at the very top of the roof.

The roof support is the walls of the building. For correct calculation the size of the ridge, as well as the rafters, it is necessary to know not only the angle of inclination of the roof, but also the dimensions of the building. To accurately make a canopy, you need to add about half a meter to the length of the rafters.

Installation of a gable roof begins with the arrangement roof trusses, which are assembled on the ground according to a template. The Mauerlat is installed around the perimeter of the building, and then it is attached to the wall using anchors. A layer of roofing felt is made between the Mauerlat and the wall.

Characteristic features of a sloping roof

A broken roof is a structure with numerous broken lines. In principle, this is a type of gable roof that allows you to create attic floor additional room.

There are the following types of broken roofs:

The reliability of the structure and its comfort depend on the type of roof chosen. However, sloping hipped roofs are becoming most popular today, since they ideally combine two features: the effective use of additional space and the low complexity of installing the rafter system. This approach involves obtaining full-fledged living quarters with small financial investments.

Polyline device hipped roof garage allows you to create full-fledged living quarters on the second floor

To build a sloping roof, it is necessary to make a fairly dimensional structure of the rafter system, however, during its construction, modular installation methods can be used, so it is not necessary to use different lifting equipment. The rafter system and racks are cut to fit the right angle in places where there are fractures of the slopes. To secure the knots, you need to use “kerchiefs” made of plywood with a maximum thickness of 2 cm.

This design hipped roof perfect for small garages where it is not possible to construct a sloping roof more complex shape. For buildings with large areas install another rafter system.

Used garage roof

An operable roof is a flat-shaped structure that has a special coating. A similar structure can be built over the entire area of ​​the building or over some part of it.

The roof in use is conventionally divided into the following types:

The construction of such a roof must comply with the standards specified in SNiP, since the operating time of the roof depends on the correctness of the selected materials, the calculations performed, and the consideration of loads.

Typically, the roof structure has a multi-layer structure, and it is done in this way:

• rigid base;
• mandatory vapor barrier layer;
• insulation;
• screed under right angle;
• waterproofing layer;
• protective separator;
• finishing coat.

An existing roof can also be constructed using granite gravel (fraction 25/32 mm), which is laid on geotextiles. In order for the roof to operate normally, gravel is laid with a thickness of at least 50 mm. Geotextiles in parallel with gravel will make the coating more stable.

The undeniable advantages of a sliding roof for a garage

Today, mobile sliding roofs, which have many advantages over traditional roofs, are of great interest.

According to its design, a sliding roof can be of the following type:

By functionality Sliding roofs are divided into:

• seasonal (the structure moves only during a certain period, usually in summer);
• permanent (used throughout the year);
• temporary (used for mobile light structures).

In addition, a sliding roof can be not only permanent, when the entire structure or a specific part of it is covered, but also attached over various buildings to the main house. Among other things, a retractable roof can also be designed over other free-standing buildings, for example, greenhouses, greenhouses or observatories.

The main elements of a retractable roof are load-bearing profiles made of aluminum, which are manufactured with a variety of protective coatings in the form of:

• anodizing;
• powder paint;
• various enamels.

To give rigidity to the profiles, a steel pipe with a square cross-section is installed inside them. However, the most durable forms of sliding roof frames are considered to be:

• dome;
• arched;
• single-pitched with a slope angle of at least 45 o.

For other types of roofs, which have a slope angle of up to 45 o, only reinforced coverings and profiles are used.

The highest quality and effective options When installing a retractable roof, coverings made of plexiglass, triplex or tempered glass are considered. Similar view panels can withstand hail up to 14 mm.

What types of materials are used for garage roofs?

A garage roof can be built from a variety of building materials, and their cost depends on the “thickness” of your wallet, and installation methods depend on the time you have. Therefore, it is worth thinking carefully about the type of roofing material for the garage.

A fairly popular and well-known material among consumers, which is affordable and easy to use. One roll is enough to cover 10 m2 of roofing and forget about it for 15 years. The main advantage of roofing felt is that this coating is inexpensive and durable, but for its use it is necessary to make a sheathing, as well as a rigid frame.

Ruberoid is one of the most inexpensive and popular materials for covering garage roofing

Waterproofing is considered high-quality, provided that it is made of at least four different layers, and different types of roofing material are used.

Corrugated sheet

This is a modern material that is replacing slate, since the service life of corrugated sheets exceeds half a century. When deciding how to cover your garage roof, consider purchasing load-bearing wall material of the NS brand. The wavy profile of the sheet is made using cold rolling. All types of corrugated sheets have an identical wavy trapezoidal shape, but the size and height of the material differs for all brands.

Corrugated sheeting is one of the most popular materials for garage roofing because it is lightweight and lasts at least 50 years

Corrugated sheeting is a resistant, fireproof, as well as water and soundproof roofing material that meets state regulations. Its advantage is its reusability.

Slate

Traditional slate is often used for garage roofing, as its service life is about 40 years at a moderate cost. The material is an asbestos-cement board, which is quite simple to install - holes are drilled into which galvanized nails are driven with an allowance of a couple of millimeters. Further, the installation of this material is carried out identically to the installation of a roof made of corrugated sheets with the only difference - the corners of the internal spans are cut off.

Slate is laid on the garage roof in the same way as corrugated sheeting and secured with special slate nails

Roof tiles

The garage roof can also be made of cement-sand or ceramic tiles. These types natural coating They last approximately 100 years and are UV resistant, fire resistant and able to withstand a wide range of temperature changes. In addition, the tiles perfectly absorb noise, do not retain static voltage and have low thermal conductivity.

To lay tiles on a gable roof, special locks are used on each product

If a roof is being built with a slope of about 12 degrees, then ideal option is a metal tile. The decking is made of galvanized steel 0.6 mm thick, which is coated polymer composition. To give the material its shape, it is stamped. Metal tiles are sold in a varied palette of colors.

Metal tiles are laid in large sheets, often corresponding in length to the dimensions of the slope

Seam roof

Metal is the lightest building material, allowing you to save money when installing the frame. Of course, when maintaining a metal structure, you will have to spend a lot of money, but this material is suitable for any type of roof. For example, planning to build metal roof, when arranging it, you can only get by with a sheathing made of beams.

To create a seam garage roof, special tools are used to form a sheet fastening profile

Installing a seam structure requires the use of special equipment and the involvement of professionals, since even minor “punctures” in the calculations will lead to distortions, which are much more difficult to eliminate than to immediately build the roof correctly.

How and how to insulate a garage roof

Every motorist dreams of a warm garage, and making the roof insulated is quite simple.

IN modern construction The garage roof is insulated in combination, that is, traditional insulation is combined with a heat insulator that reflects light and does not allow infrared radiation to pass through. However, in some cases such costs may be unreasonably high, for example, if the building is detached. Then use classic materials such as:

1. Mineral wool. She has wonderful technical characteristics. It is used only with hydro- and vapor barrier material, which protects mineral wool from water. In addition, mineral wool is quite affordable.

   
   Mineral wool is inserted into the cells between the rafters and secured with wire or fishing line before the final ceiling covering is laid

2. Glass wool. This material is cheaper than other insulation materials, but has a low degree of fire resistance. If you plan to make a pitched roof, then it is better to buy a special type of glass wool, which differs high density structures. This material is produced in rolls with a width equal to the normal distance between the rafter legs.

   
   Glass wool is one of the most inexpensive and available materials for roof insulation

3. Styrofoam. This is a waterproof material, which in its thermal insulation characteristics is similar to mineral wool. Polystyrene foam is a flammable insulation material, but the PBS-S brand with the addition of fire retardants has the property of self-extinguishing. Due to these features of the material, it is used as insulation for garage roofs. In addition, it does not rot, mold and mildew do not form on it.

   
   Laying foam plastic in the sheathing of a garage roof does not require special skills

4. Penoizol. It is a liquid foam, but with best performance. It is resistant to fire and water, hardens when placed in a confined space, and forms an ideal seamless coating. With all this, penoizol is cheaper than any sheet foam, and its service life is about 40 years without loss of characteristics.

   
   To insulate the roof with foam insulation, it is necessary to use special equipment for spraying

You can also use traditional options for insulating a garage roof, for example, using sawdust, but they cannot be compared with modern materials.

The garage space is an object with a high probability of fire, so it is necessary to purchase insulation with improved fire resistance characteristics.

Insulating the garage roof from the inside

Required Tools:

• special buttons or furniture stapler with staples;
• vapor barrier film;
• carpentry tools;
• self-adhesive tape;
• waterproofing;
• insulation.

Thermal insulation of the roof from the inside is carried out as follows:

Such a cake is placed not only on wooden beam structures, but also on reinforced concrete slabs. Before installation, the beams are protected with sheet material, after which waterproofing is attached to it, then insulation and vapor barrier.

Avoid contact waterproofing film with insulation, there must be a certain distance between these materials for ventilation. Direct contact is only allowed if a superdiffusion membrane has been used.

We insulate the garage roof from the outside

From the outside, the roof is insulated during the construction stage, since it is not very convenient to open a completed building in order to correct shortcomings. Please note the presence of a vapor barrier, which must be installed on the side of the room. This way you can prevent not only re-condensation of vapors, but also avoid unpleasant leaks.

How to repair a garage roof

Leaking is the main nuisance that a garage roof brings, and the reasons for this may be:

• exhaustion of the strength resource during operation;
• negative impact of weather;
• incorrect roof installation;
• mechanical damage due to careless cleaning of the roof from snow cover;
• low quality finishing material;
• neglect of the installation of waterproofing;
• violation of installation standards when using roofing material.

Leaks must be eliminated at the stage of mold or wet spots appearing. Initially, it is worth checking the joints and joints, then the integrity of the roof for holes, chips or other damage. In addition, it is necessary to eliminate various types clogging, for example from dry leaves, which clog the corners of the roof and accumulate moisture.

The method of eliminating a leak depends solely on the amount of damage and the characteristics of the roofing material. Partial renovation can be carried out for small-piece and soft roofing materials. Volume repair work for panel and sheet materials depends only on the complexity of the structure and its damage.

Using roofing felt, you can quickly and inexpensively completely repair your garage roof and get rid of leaks

When preparing drawings and a garage roof project, immediately include in the estimate an extra 10% for other expenses that are difficult to foresee.

High-quality construction garage roofs - best option minimize your expenses if you have necessary knowledge in construction. The choice of material and tools has great importance when arranging the roof. Just read the necessary information and you can do all the work yourself. We wish you success!

When building a garage, few people choose complex and intricate designs. Simplicity, efficiency and reliability come first. The roofs being erected usually have a gable or single-pitched shape. The latter option is faster and easier to build; it involves less material costs. But sometimes a property owner needs attic space to store tools and other property. For this purpose, you can make a gable roof. Be that as it may, you will need materials for the simplest rafter system, insulation, hydro- and vapor barrier films, as well as roofing material. The covering must retain heat inside to make being in the garage as comfortable as possible.

Flat garage roof design

If you are thinking about the question of how to make a roof on a garage, then you can consider it as an option flat design, which is suitable if reinforced concrete floor slabs were used during construction. In this case, the rafter system will be present if there is a need to form an attic space. By concrete base usually settles down soft roof, where the material is roofing felt, fiberglass or bikrost. This option is economical, and the reinforced concrete base protects the building from unwanted guests.

The slab must be positioned with a certain slope; for this, the opposite walls must be at different levels. If you haven’t learned this, the slope under the roof can be arranged using rigid insulation and screed based on cement and sand.

Features of flat roof construction

Many people today are thinking about the question of how to install a roof on a garage. If it is flat, then it minimum slope should be between 2.5 and 3°. A flat roof is sometimes made of wood; for this, floor beams are laid on the walls of the building, their ends must fit into the nests formed during the brickwork. On top of the beams there is a continuous flooring of boards, the thickness of the latter should be 30 mm or more.

Next, a soft roof is installed. provide for the presence of a certain space under the roof in the rafter system. If the building is attached to residential building, then the roof should be pitched. It will become a kind of continuation of the one that exists on the house. When choosing roofing materials for it, you must choose ones that are similar to the coating of the main building, which concerns not only the material, but also the color. Gable roofs are done in the case when the garage acts as a separate structure. Other types of roofs are used quite rarely.

Shed roof and its structure

Before making a roof on the garage, gable or single-pitch, all wooden elements of the rafter system are treated with fire retardants and antiseptics, this is the only way to protect the materials from fire and rotting. A pitched roof is erected with an angle of inclination that does not exceed 30°; for this purpose, one of the end walls is located at a more impressive height. This is true if the pediment is made of brick and becomes a continuation of the facade wall.

Then you can begin the construction of the rafter system. A reinforced concrete armored belt needs to be poured along the top of the brick walls; it is installed before laying the Mauerlat. The armored belt will bear all the loads. Before making a garage roof using this technology, you may also want to think about whether an armored belt is needed. They refuse it, if they are present in the system, they will act as tie-downs for the rafter legs. Beams must be laid at a distance of 70 to 100 cm; they are inserted into special holes between the bricks. The ends of the beams must be wrapped with roofing felt, this is necessary to prevent the material from coming into contact with the brick, this will prevent rotting. Then the master can proceed to installing vertical posts; they should be tied together and placed on the beams. As a result, you should get a structure that consists of two triangles, each of which will rest on the wall with a long leg, while the short leg will rest on brick facade roofs. When installing a pitched roof for a garage, the hypotenuse of the triangle should form the roof slope. The structures are connected to each other by transverse beams, and a sheathing is installed underneath them for installing the roofing material.

More information about a wooden garage roof

The wooden roof of the garage can be gable; for this, the frame is formed according to a fairly simple project. To do this, it is necessary to equip rafter legs, which are arranged in two rows and have an identical shape. Such elements should be located on two parallel walls. The rafter legs are connected at the tops by a single ridge. The steeper the slope, the greater the number building material will be required for the construction of the rafter system. We should not forget about the length of the rafter leg, to which is added a distance equal to the allowance for the visor. The finished rafters should be filled with a sheathing system with the required spacing, which is determined depending on the size of the roofing material.

To form the sheathing of a pitched roof, you need to purchase a square block with a side of 5 cm. A 25-mm board, the width of which varies from 15 to 20 cm, is also suitable. Depending on what roofing material you choose for the sheathing, you can make a structure continuous or with a certain pitch, the latter must correspond to the dimensions of the roofing material. A pitched roof for a garage will allow you to create an attic space. It will not be possible to use it completely, but it is possible to equip it with good insulation.

Selection of roofing materials

For roof covering you may prefer different materials, for a flat roof are suitable:

• roofing felt;
• bikrost;
• ondulin;
• broken glass

If we are talking about a pitched roof, then you can use:

• metal tiles;
• profiled sheet;
• galvanized smooth sheet.

Roof covering with roofing felt

Iron garage can be covered with roofing felt, which is used for flat roofs. To do this, you will need a continuous frame sheathing, and the ceiling itself must be formed from waterproofing must be laid between the roofing felt and the slab. This will create reliable protection from moisture. Ruberoid is sold in rolls, and it must be laid in several layers. The bottom two will be lining, while the top one will be the cover, it should be the densest. An iron garage can be saved from moisture using roofing felt; for this, the surface is lubricated bitumen impregnation. Next, the first layer is spread, located parallel to the conditional ridge. It is important to ensure a 10 cm overlap. Additionally, the material is secured with nails or self-tapping screws, the distance between which should be 30 cm. Next, the surface is covered with bitumen impregnation, onto which roofing material is laid, this time it must be positioned perpendicular to the first layer. The strips must be laid overlapping and secured. The edges are folded inward. The resulting “pie” is once again treated with bitumen impregnation to cover the third layer of roofing material; it should also be positioned perpendicular to the second.

It is important to remember the need for fasteners and overlaps. The service life of such a coating will be approximately 15 years, after which the surface will require updating. Prefabricated garage can also be covered with roofing felt, instead of which more modern analogues such as euroroofing felt or rubemast are often used. These materials have higher ductility, and their service life reaches 30 years. Analogs of traditional roofing felt can be used on pitched roofs; they have a more attractive appearance.

Preparation of tools and materials before laying euroroofing felt

If you decide to use euroroofing felt for arrangement, then you need to stock up on a certain set of tools and materials, including:

• euroruberoid;
• bitumen mastic;
• blowtorch or gas torch;
• metal hook.

Working with euroroofing felt

A prefabricated garage can be covered with euroroofing material. It is easier to install than regular roofing felt. There is no need to treat the base before starting work. The material is heated and laid. To achieve the best effect, it is necessary to treat the base with bitumen mastic. The bottom layer of material is heated with a blowtorch until the layer boils. The surface also heats up. Use a metal hook to unscrew the roll, laying the roofing material without forming folds or air pockets. Such roof waterproofing can be laid in one layer, but overlaps are still necessary. Its width can be 150 mm. In order to prevent leaks, the material should be laid next to each other. standing garages 100 mm or more. For safe heating, it is best to use blowtorch, however, it requires a large number of fuel. Sometimes a gas burner is used in the work, which is more effective, but dangerous due to the gas cylinder.

Concrete roof

Waterproofing for concrete roofs is especially necessary. The lower beams are covered with boards, a layer of roofing material is laid on top, which can be mounted dry or on a metal sheet to create a base. Sometimes the support does not seem reliable enough; it may simply not support the weight of the roof. In this case, it is necessary to ensure the presence of supports; one will be enough for 50 m2.

Next, formwork is constructed for pouring concrete. Reinforcement is placed across and along the beams, the cells of which should be equal to 200x200 mm. In order to avoid excess consumption of the solution, crushed stone is placed under the reinforcing mixture. When pouring concrete, care must be taken to ensure that the mesh does not move. Concrete roof The garage is equipped by pouring the mixture in equal portions, which should be leveled over the surface. From time to time the formwork is tapped, this will allow the solution to lie more evenly.

Conclusion

Now you know how to garage. For this you can use the most modern materials, but some prefer to save money by using, for example, roofing felt. It is worth considering how long you will be ready to carry out repairs, because sometimes it is more advisable to use materials that have a longer service life. And if you want to save money, then it is better if you install a flat garage roof, since it requires less material than any other.
