If your home requires a roof that has an attractive and sophisticated look at a relatively low cost, a corrugated roof — cold-rolled galvanized steel sheet coated with non-ferrous polymer materials- This is what you need.

Advantages of profiled steel sheet:

• excellent performance: resistance to atmospheric factors, solar radiation, mechanical strength, corrosion resistance,
• low specific gravity (from 5.5 to 9.5 kg/m2), therefore low load on rafter systems and lathing,
• roofing material can be selected according to texture and color to match the design of the building,
• relatively low price with high aesthetic qualities.

Which corrugated sheeting is suitable for the roof

Any brand of corrugated sheeting (universal, load-bearing or wall) is suitable for roofing, but for laying thin wall material An almost continuous sheathing will be required. For ordinary lathing with a pitch of 65-100 cm, it is preferable to use a stronger and more rigid profiled sheet. The most commonly used material is with the following indicators:

• grade N or NS (load-bearing and universal),
• corrugated sheet thickness from 0.5 to 0.7 mm (strong and light at the same time),
• corrugation height 20-75 mm (provides the possibility of elastic deformation of the roof),
• the presence of a capillary drainage groove,
• coating color that matches the existing or planned exterior of the house.

The price of corrugated sheeting depends on several indicators of the material.

What you need to cover a roof with corrugated sheets yourself

A simple single-slope or gable roof country house, summer kitchen Covering a garage or garage yourself will not be difficult with one or two helpers and some skills in working with a screwdriver and a jigsaw. A broken gable roof of a house with an attic will also be suitable for independent work. This video will help.

If the roof frame is more complex configuration, should be invited experienced specialists to cover the roof with corrugated sheeting. The price of the work will depend on the complexity of the roof and the area of ​​the slopes.

How much material will be needed

Calculating the amount of material for a single-pitched or gable roof, knowing the size of the slopes, is not difficult. If the length of the slope is 12 m or less, you need to divide the width of the slope by the width of the material, and increase the resulting number of sheets by 15%.

For more complex roofs, you can calculate corrugated roofing sheets online using special programs. The programs allow you not only to determine the amount of material as accurately as possible, but also calculate the slope of the roof, the dimensions of the overlap, and determine best option location and fastening of corrugated sheets.

Tools and fastening materials for work

To work you will need measuring and cutting tools, fastening materials:

Features of laying roofing from corrugated sheets

It’s best to do the work with four people, it will work out much faster. Two people can handle it too, but working alone is difficult. long sheets corrugated sheets are very difficult.

• The minimum roof slope angle is 10 degrees. With a smaller slope angle, water can get under the material.
• The standard length of the profiled sheet is 12 m. If the length of the slope is shorter or longer, the sheets will have to be cut.
• To protect the corrugated sheet from corrosion, waterproofing and vapor barrier should be done along the sheathing.

Installation of sheathing under profiled sheets

An important step in installing a roof made of corrugated sheets is the organization of hydro- and vapor barriers to protect the metal from corrosion when water vapor enters.

They do this in two ways:

• laying a vapor barrier on the rafters under the sheathing and waterproofing (roofing felt) on top of the sheathing under the corrugated sheeting;
• organizing a ventilated roof, creating a ventilated space between the waterproofing layer and the roofing material. To do this along rafter legs they install false rafters from bars along the waterproofing, make lathing on them, you get a layer cake: rafters, waterproofing, false rafters, lathing, corrugated sheet.

Important! All elements of the sheathing must be impregnated on all sides with an antiseptic composition for wood. This will extend the life of the roof.

The sheathing boards are laid in increments of 0.5-1.0 m, attaching them to the rafters with nails or self-tapping screws. The thicker and more durable the corrugated sheeting is used, the greater the distance between the sheathing boards. So, for example, for profiled sheets of grade CH35, the lathing pitch is 0.5-0.6 m, for CH44 - 0.65-0.75 m. A distance of more than 1 m between the boards should not be made.

Having made the sheathing, you need to check the diagonals of the slope and align the slope along the verticals, horizontals, and diagonals. This will greatly facilitate the work of laying corrugated board on the sheathing.

The procedure for laying corrugated sheets with your own hands

• Corrugated sheets are laid from bottom to top, starting along the slope from the end of the building, from left to right or from right to left - it all depends on which side of the sheet the manufacturer made the capillary groove on. When laying the material, the groove should be closed by the wave of the next sheet.
• The size of the overlap of corrugated sheets horizontally and vertically depends on the angle of the roof slope. For small values ​​of the angle of inclination of the slope, the sheets are laid with an overlap in two waves vertically, for high values ​​- in one or half a wave.
• The horizontal overlap of the slope is at least 10 cm. The first row is laid with an overhang of 30-50 cm above the overhang (the distance depends on the design drainage system). The joints between the profiled sheets are sealed with a special tape. The sheet of the second row is laid with an offset along the end by half the width.

If 2 or more people, lifting the sheets is easy. They are laid on a frame of 5-6 bars in packs of 5-10 pieces and pulled up with a rope along inclined boards attached to the sheathing.

To prevent the sheets from rolling off, nail one or two bars from below onto the sheathing and place a pack of covering sheets. It’s much more convenient to work this way than to feed one at a time, although this method is also used.

How to attach corrugated sheets to the roof correctly

The sheets are secured to the sheathing with self-tapping screws, washers and sealing gaskets. Their number is no more than 6-10 pieces per 1 sq.m. flooring On the slope, screws are screwed into the lower ones, and on the ridge - into the upper waves of the sheet.

If the material is thin, the screws are simply screwed in with a screwdriver; they easily pass through without damaging the coating. For fat people steel sheets In the places where they are attached to the sheathing, it is advisable to make preliminary markings and drill holes for the self-tapping screws with a drill.

Important! It is necessary to accurately align and correctly install the very first sheet; the quality of the entire work will depend on it.

The first sheet is first secured in the middle with one screw and the overhang from the eaves and the vertical position of the sheathing are carefully aligned. After this, it is secured with a second screw.

The material is attached to the upper and lower boards of the sheathing by screwing screws into each deflection of the wave, into the central boards - through the deflection.

The second highest row is placed with the sheets shifted to the right or left by half the width. Cut the profiled sheet with an electric saw, a hacksaw or a jigsaw with a metal file. They do it on the ground.

Attention! You cannot cut profiled sheets with a grinder. This will destroy the polymer coating. For cutting, use metal scissors, and paint over the sections.

Horizontal joints are also sealed with tape. Overlapping screws are screwed into each recess of the wave. The rubber sealing washer should protrude 1-2 mm around the perimeter of the screw head, this indicates that it is not pinched or loose.

Installing a ridge on corrugated sheets

Ridge additional elements for corrugated roofing are produced

• simple in the form of a sheet bent at an angle with a shelf width of up to 30 cm,
• with a semicircular edge,
• with a U-shaped edge and shelves of the same dimensions.

To install a ridge on a roof made of corrugated sheets, the last row of sheets should be aligned at the top along the end and laid in one horizontal plane. The installation procedure is as follows:

• a tape or strip of ridge seal is placed on the edge of the last row of sheets,
• bars are fixed parallel to the ridge axis,
• screw the ridge elements to the bars with self-tapping screws into the upper corrugation after 20-30 cm, starting from the side where the wind most often blows,
• the ends of the semicircular ridge are closed with special plugs,
• The U-shaped ridge is attached to a block, which is specially installed under it on the roof ridge.

A roof made of corrugated sheets will delight you with its beauty and evoke a feeling of pride in the excellent work done with your own hands. The money saved on this can be spent on making an original weather vane that will decorate the house.

In the article I will tell you how to properly cover a roof with corrugated sheeting, starting from the selection of material and ending with the technology of attaching it to the sheathing. The information provided will help you plan your work correctly to achieve the desired result with minimal investment of time, effort and money.

Use of profiled metal sheet as roofing material It has whole line advantages:

1. Strength and durability. Given that correct selection and installation in compliance with all requirements, corrugated roofing can last 30 years or more without requiring repairs.
2. Resistance to external influences. When producing high-quality corrugated sheets, the steel base of each sheet is covered with several layers of anti-corrosion coatings. Thanks to this, the metal does not rust and retains its strength.
3. Light weight. The weight of corrugated sheeting is about 6 - 8 kg/m2, which allows you to lift it onto the roof without the use of special equipment. The second plus is the low load on the load-bearing structures (rafters, sheathing), which allows savings through the use of thinner beams and boards.

1. Fire safety. The corrugated sheet not only does not burn itself, but also prevents the spread of fire.
2. Price. If we exclude the cheapest slate, then covering the roof with corrugated sheeting can confidently be called the most affordable method. If you want to save money, choose corrugated sheets.

Now about the cons:

1. Corrosion on the cut. As I noted above, cut edges and places where we screw screws are potential sources of corrosion. State metal base These areas need to be monitored and measures taken at the first signs of rust.

1. Heating in the sun. IN summer period a roof made of corrugated sheets heats up very much, so the temperature in the under-roof space and in the room itself also increases. This problem is partially solved by installing thermal insulation on the inside of the roof slopes, but only partially.
2. Disgusting soundproofing. For me, this is the most serious drawback that significantly limits the use of corrugated sheeting as a roofing material for residential buildings. You can hear everything - rain, hail, wind, birds, even cats! Again, a layer of thermal insulation using porous materials partially absorbs sound, but does not completely eliminate it.

The controversial point is the appearance. On the one hand, corrugated roofing looks neat, and in some ways even ascetic. On the other hand, corrugated sheeting cannot be confused with other roofing material, so the roof will still look “cheap” to some extent. That is, there is not much difference for a garage or barn, but the design of a residential building may suffer.

What do you need for work?

Materials

Be that as it may, but very often positive properties the profiled sheet is outweighed and chosen as the main roofing material.

To install a corrugated roof with your own hands you will need:

1. The corrugated sheet itself has a base thickness of 0.5 to 0.7 mm. For roofing work, grades from C8 - C21 to C44 - H60 are suitable. The lower the planned load on the roof, the smaller the profile size you can choose.
2. Additional elements made of profiled metal. This should include internal and external valleys, end strips, drip edges, linings for masking the joint with the walls, etc.

1. Lumber for creating sheathing - beams 40x40 or boards 100x30 mm.
2. Board materials (plywood, OSB board) 15 mm thick to create a continuous sheathing.
3. Roofing waterproofing membranes.
4. Thermal insulation materials (most often mineral fiber-based boards).

1. Sealing tapes for filling cavities around the perimeter of the roof. It is best to purchase a tape made of porous material, the profile of which matches the profile of the roofing sheet.
2. Fasteners – nails and self-tapping screws for installing sheathing, self-tapping screws for corrugated sheeting.

TO additional materials I would consider a vapor barrier membrane designed for installation on the inside of an insulated slope. Also worth purchasing antiseptic impregnation for the wood with which we will process both and the sheathing parts.

Tools

To properly cover the roof with corrugated sheeting with your own hands, we will need the following tools:

1. Wood saw for cutting beams, boards and plywood for sheathing.
2. Manual or electric metal shears for cutting corrugated sheets.

Under no circumstances should you cut corrugated sheets with a grinder. When in contact with a grinding or trimming disc, the metal heats up, which leads to the destruction of the anti-corrosion coating. As a result, the roof will rust very intensively at the cutting line.

1. Screwdriver for quickly tightening screws.
2. Construction stapler.
3. Knife for cutting waterproofing membranes.

1. Knife or saw for insulation.
2. Measuring tools – plumb line, level, tape measure.

To increase productivity and ensure safety, it is important to properly organize work at height. You need to move along the roof slopes only with a safety harness securely attached to the ridge area. It is advisable to carry tools in a special belt with pockets.

Another tip is to fence off the area adjacent to the roofing work site. This way you will reduce the risk of injury to others, because both tools and roofing parts tend to fall at the most inopportune moment.

Preparation

Calculation

In order to properly cover the roof, it is necessary to perform at least an approximate calculation of the load-bearing capacity of the sheathing. If you make it too thin, the corrugated sheeting will “play” under its own weight, which will ultimately lead to weakening of the fasteners and the appearance of leaks.

On the other hand, too dense lathing requires the use large quantity material. Hence the increase in weight load and the rise in cost of the structure as a whole.

To select the optimal sheathing pitch, you can use the table:

The calculation is given for sparse lathing, for which boards 100 x 30 mm or beams with a cross section of 40 x 40 or 50 x 50 mm are used.

When installing continuous sheathing, plywood with a thickness of 15 mm or more is used. It is permissible to use oriented strand board (OSB) with similar thickness and load-bearing capacity.

When calculating the volume of purchases of materials for installing the sheathing, you need to keep in mind that not only the width and length of the roof slope are taken into account. It is also necessary to take into account the projection of the roof (horizontal projection beyond the gable) and overhang (lateral projection beyond the front of the mauerlat). In these areas, sheathing is also being done for the roof, so the purchase of material must be carried out taking into account the dimensions.

Thermal and waterproofing

Before covering roof with corrugated sheets, we need to compensate for its shortcomings - poor heat and sound insulation properties. In addition, additional waterproofing should be provided: no matter how well we install the profiled sheet, there will still be leaks.

We carry out work on the formation of the “roofing pie” according to the following scheme:

1. We lay slabs between the rafters thermal insulation material – mineral wool thickness from 75 to 150 mm. From the inside, we cover the insulation with a vapor barrier membrane and fix it with a counter-lattice - cross beams or plywood sheathing.

1. WITH outside we install vapor-permeable waterproofing membrane. The vapor permeability of the material is very important because it preserves natural ventilation roof and prevents condensation from accumulating in the thermal insulation layer.

1. When installing waterproofing, we roll out the membrane rolls horizontally, going down from the ridge to the eaves. We fix the material on each rafter with several galvanized staples.

1. An important parameter is the size of the overlap of the material: the smaller the slope, the wider the double layer should be at the junction of the rolls. The optimal overlap for slopes with a slope of 30 degrees or more is 150 mm, for slopes with a slope from 12 - 15 to 25 -28 degrees - at least 200 - 250 mm.
2. To minimize the risk of water leakage, you can use double-sided adhesive tape (almost every waterproofing manufacturer has it in its line of materials). We tape all the joints, securely fixing them and protecting them from displacement.

Lathing

To cover the roof according to all the rules, we need to install reliable sheathing.

It’s easy to do this based on the above calculation:

1. For the sheathing we take boards and beams with suitable dimensions. Optimal wood species are pine, spruce and larch. The maximum permissible humidity is 18%, if more, it is advisable to dry the wood in the shade, avoiding cracking.

1. Before purchasing, we check the parts for knots, rot and wormholes. Appearance wood is not so important, but strength comes first. So if there are defects, it is better to refuse the purchase.
2. It is also worth checking the geometry of the timber/board. We don’t need a perfectly smooth surface, so we shouldn’t buy expensive jointed materials. Another thing is curvature: the smoother the parts are, the better the frame will be, and the less effort we will spend on its installation.

1. Even if the tree looks flawless on the outside, we treat it with antiseptics. It is advisable to take a non-washable composition with a high content of active ingredients. The disadvantage of such products is the coloring of the wood, but in our case this disadvantage does not play a role.

An additional advantage in processing may be a reduction in the flammability of wood. This effect is ensured, for example, by the use of the Senezh FireBio Prof composition or similar solutions.

Now - the installation of the supporting structure itself:

1. First, we fill the ends of the rafters with thicker boards - the so-called cornice supports. You can place a thin metal corner – a drip edge – under the cornice support. It is inserted under the waterproofing material and ensures effective hardening of condensation from the wall surface.
2. We lay the sheathing elements perpendicular to the rafters. For fixation, we use either nails or phosphated wood screws.

1. We attach the timber to the rafters at one point, and the board at at least two. By fixing the board at the top and bottom, we prevent its deformation: if you install a nail in the middle or only on one side, then a fairly wide element can “go undulating.”
2. During installation, we control the geometry of the sheathing. Tolerance is about 2 mm per 1 m. For control, it is convenient to use two levels: long - 2 m, and short - 50-60 cm.

1. When installing sheathing on a wide roof, it becomes necessary to join the beams. According to the rules, joining is performed only on the rafters: the parts are trimmed, each edge is secured with separate fasteners, after which a connecting bracket is hammered into both boards.

1. Finally, gutter fastenings can be installed on the bottom of the slopes. We fix these parts either to the cornice board or to the end beam, which is pressed onto the rafters themselves.

So, the future roof is insulated, waterproofing is laid and bearing structures mounted. Now all we have to do is actually cover the roof, attaching sheets of corrugated sheets and additional elements to it.

Roofing

Installation of corrugated sheets

We begin fixing the roofing material on the sheathing with our own hands with installation additional elements located under the corrugated sheet. As a rule, these are lower valleys, which must be fixed at the junction of the planes to protect them from leakage, and cornice strips.

When this operation is completed, you can begin covering the main surface of the slopes.

The instructions assume work in the following sequence:

1. The starting point is the lower left corner of the ramp. If you start here, you can most effectively overlap the sheets by overlapping the capillary grooves.

1. To begin with, we lay several sheets, align them with the gable overhang and eaves overhang, and secure each with one self-tapping screw. We install along the end of the corrugated sheet sealing tape, covering the gap between the sheathing and the corrugated parts of the material.
2. When laying, the leftmost wave of the sheet is superimposed on the rightmost wave of the already laid one. This overlap is mandatory because it ensures no leakage..

1. After several parts have been laid (I usually install three sheets in the first row from the bottom, and two in the second), we begin the final alignment with fixation. For fastening we use self-tapping screws with a hexagonal head and a sealing washer.
2. We fasten it to the bottom of each even wave of the corrugated sheet. After this we make from 4 to 10-12 attachment points on square meter material, distributing the screws in a checkerboard pattern.

1. We separately fix with self-tapping screws the places where the sheets join. You can simply tighten the corrugated sheeting with regular fasteners, but I prefer to screw long self-tapping screws into the overlap area. They reach the sheathing and give the structure additional rigidity.
2. When we independently cover the roof with corrugated sheeting, it is extremely important to control the tightening forces of the fasteners. The neoprene gasket should be pressed against the metal, but not crushed or distorted. With proper compression, the material self-vulcanizes, and the fastening site becomes almost airtight.

1. When working with thin (0.5 -0.6 mm) corrugated sheeting, it is also important to avoid deflection at the fastening point. The consequences of over-tightening will be the formation of dents in which water will be retained as it drains, and sooner or later will leak inside.
2. Another trick is pre-drilling. If a corrugated sheet with a thickness of 0.6 - 0.7 mm is used for the roof, then at the fastening points it is worth drilling holes whose diameter will be approximately 0.1 - 0.2 mm larger than the diameter of the working part of the screw. This will make installation easier and, in addition, ensure the mobility of the roof during temperature deformations.

1. We cut the outermost top and side sheets to length/width and fix them to the sheathing with additional fasteners.

The installation method described in this section is used when roofing a roof with piece corrugated sheeting of a fixed width. At the same time, it is now possible to order material whose width will be equal to the width of the roof itself - in this case, you will not have to waste time joining individual sheets.

Installation of additional parts

Installing corrugated sheets on slopes is the most labor-intensive, but not the most painstaking part of the work.

After completing this stage, we need to install additional elements:

1. At the junction of the rafters on ridge beam place the board on its edge and fix it metal corners. We place a ridge profile on top of the board, which we fasten with self-tapping screws.

We glue a porous sealant tape under the side strips of the ridge profile, which will ensure the tightness of this unit.

1. We install end strips along the gables. The vertical part of the plank is attached to the end board of the sheathing, the horizontal part covers the outermost wave of corrugated sheeting and is fixed on it. You can also place sealing tape under the end strip.

1. Where the planes of the slopes meet, we install upper valleys.

1. Joints between corrugated sheets and chimneys, vertical wall and cover with other surfaces corner parts– abutment bar.
2. We must place sealing material under the plank, and fasten the part itself with elongated self-tapping screws that reach the sheathing or rafters. The contact point between the plank and the wall can be additionally sealed liquid composition or butyl tape.

Conclusion

A roof made of corrugated sheets, constructed according to this scheme, will provide effective protection of the house from moisture for many years. To understand the technology in more detail, it is worth studying the video in this article. In addition, questions regarding difficult stages of work can be asked in the comments.

Creating a roof always involves a lot of various nuances, requiring attention. Errors made during design and installation always cause premature destruction of the roof, so they should be avoided by thinking through all stages of construction work in advance.

One of the problems is the selection and installation of roofing material. In recent years, corrugated sheeting has been increasingly used for roofing, the most important advantage of which compared to other roofing coverings is its ease of installation, which allows you to do everything necessary work on one's own. How to cover the roof yourself with corrugated sheets will be discussed in this article.

Characteristics of corrugated sheets

The corrugated sheet is sheet material made of steel with zinc coating. Sheets often have a polymer coating, giving the material additional protection from external factors. Characteristic feature corrugated sheeting is the presence of a profile, due to which the sheets acquire greater rigidity. Since the rigidity of the material is achieved without increasing its weight, it ultimately turns out to relieve the entire roof structure.

Covering the roof with corrugated sheeting is carried out in several stages, proceeding in the following sequence:

• Choice suitable material;
• Taking measurements;
• Transportation;
• Preparation of tools;
• Preparatory roofing;
• Direct installation of the coating.

Material selection

There are several parameters that need to be carefully studied when choosing profiled sheets for roofing:

1. Marking. There are several types of profile sheets, but for the roof, the best products are those marked H, which were originally developed as roofing. When choosing a specific brand, you must pay attention to the wave height, which should be at least 20 mm, and the usable width of the sheet. You can use general rule: with an increased roof slope, it is worth choosing a lower grade of corrugated sheeting. It will not be superfluous to study the quality certificate when purchasing material.
2. Presence of defects and damage. Of course, you should not use damaged or deformed corrugated roofing sheeting. There should be no cracks, roughness or other defects on the surface of the profile, and the coating should be intact. If the sheet bends too easily or breaks at the slightest bend, then it is strongly not recommended to use it. In addition, really high-quality corrugated sheeting, after bending, returns to its original state on its own.
3. Price. This parameter is especially relevant with a limited budget allocated for construction. The cost is affected by the thickness of the products and the type of coating. U different manufacturers There may be exactly the same corrugated sheets, so it’s worth studying the market and choosing the most suitable option.
4. Type of coverage. To protect corrugated sheets from corrosion, a zinc coating is usually used. The thickness of the protective layer varies, so you need to select the material taking into account the operating conditions. In addition, most profiled sheets also have a polymer coating, which provides additional protection and improves the visual quality of the material. It is worth noting that corrugated sheeting is used not only for roofing. For example, quite often interfloor slabs are made using corrugated sheets, which makes it possible to quickly carry out such work.

Taking measurements yourself

Before closing old roof corrugated sheeting, it is necessary to carry out a number of measuring operations:

• It is necessary to measure all elements roofing structure and adjust them to required sizes;
• Roof slopes are given Special attention, which is associated with a possible change in the dimensions of the structure during installation rafter frame;
• The discrepancy between the lengths of the diagonals of the roof slopes cannot exceed 2 cm, otherwise it will have to be redone supporting structure;
• Roof slopes should not have height differences of more than 5 mm per 5 m of length.

Transportation of corrugated sheets

Profile sheets, despite high performance mechanical strength, if improperly transported, they may well become deformed and become unusable, so you must follow these recommendations:

• To transport corrugated sheets, a solid and durable base is required, the length of which exceeds the length of the sheets;
• The sheets must be firmly secured so that they do not rub or move during transportation;
• You need at least two people to load and unload the material, since it is impossible to drag or bend the corrugated sheets;
• You can lift sheets directly onto the roof only one at a time, using stretched wooden logs.

Roofing Tools

In order to cover the roof with corrugated sheets, the following set of tools is required:

• Scissors (for thin profiled sheets, nibblers or lever shears are suitable, and for products with a thickness of about 1 mm, it is best to use an electrically driven device);
• Drill;
• Tool for applying sealant;
• Riveting pliers;
• Knife for cutting thermal insulation material;
• Construction stapler;
• Template for installation of lathing;
• Wire cutters;
• Screwdriver;
• Marker;
• Roulette and level;
• Hammer;
• Lace.

Preparatory work

The entire preparation stage comes down to the arrangement of the rafter frame and sheathing - mandatory elements that are part of any roofing structure. In addition to their supporting function, these elements evenly distribute the weight of the roof and allow it to withstand certain operating conditions.

A correctly designed and assembled sheathing greatly simplifies the covering of the roof with corrugated sheets - it is attached directly to its elements. The presence of a full-fledged sheathing also ensures ventilation of the roofing pie, which reduces the impact of moisture on the structure.

Corrugated sheeting installation technology - how to cover it yourself

Before covering the roof with corrugated sheets with your own hands, you need to determine the amount of overlap of the sheets, which is determined depending on the slope of the slopes:

• When the slopes are inclined less than 15 degrees, the minimum overlap is 20 cm;
• If the angle of inclination is within 15-30 degrees, then the overlap should be from 15 to 20 cm;
• When the roof slope is over 30 degrees, the overlap of corrugated sheets can be reduced to 10-15 cm.

When all stages of preparation are completed, you can begin to cover the roof with corrugated sheeting, for which the following algorithm is used:

1. Using a screwdriver and self-tapping screws, the corrugated sheeting is attached to the sheathing. Fastenings must be made in places where the wave bends. To ensure reliable fastening, you need to select galvanized screws with rubber seal. The consumption of fasteners is usually about 6-8 units per square meter.
2. At the top and bottom of the slopes, self-tapping screws are screwed into the bottom wave of sheets, and all other sheets are attached to each sheathing board. The corrugated sheets are connected to each other in the upper bend with a fastening pitch of about 50 cm.
3. Last page, located on the gable side, is usually laid with a large overlap or trimmed to the required size. The end strip must be installed with an overlap of at least 5 cm, and its fastenings must be located in increments of 30 cm so that the element covers the first wave of the sheet.
4. You also need to install the eaves overhang board in advance. It is installed with an overlap of about 10 cm. The pitch of the cornice fastenings is 30 cm.
5. To arrange internal joints, you need to use corrugated sheeting with a smooth surface. The roof under the joint should be covered with the most durable material possible. The space between the edge of the corrugated sheet and the internal joint must be filled with a sealant. At the top of the wave, the joint is connected with nails, and at the bends with self-tapping screws. The fastening step is 30 cm. The end of the corrugated sheet is placed under the ridge strip, and the remaining cracks and gaps are carefully sealed.
6. The last stage of the work is the installation of the ridge strip, the elements of which are installed with a 10 cm overlap and fixed every 30 cm with self-tapping screws.

That's it for the montage. roofing completed.

Conclusion

This article discussed the question of how to cover a roof with corrugated sheets with your own hands. This work is not difficult if you approach it wisely and competently carry out each stage of roof arrangement.

Corrugated sheet is an excellent roofing covering that can be used to finish the roofs of almost any residential or commercial building. For each individual case, the use of a corrugated sheet of the appropriate type is provided, but the procedure for its installation in most cases remains unchanged.

The corrugated sheet consists of a sheet of steel and a special zinc coating, which protects the material from corrosion. It is best to cover the roof with expensive polymer-coated material. In high-quality sheets, zinc is additionally coated with chromium, after which it is primed and exposed additional processing polymer paint and varnish material.

For finishing roofs, a universal sheet and a wall variety of material are most often used. When choosing a material, be sure to pay attention to the type and height of the corrugation. In the case of roofs, it is best to use a “wave” with a height of 21-35 cm. A “trapezoidal” corrugation of the same height is also perfect. Optimal thickness the leaf is at the level of 0.8-1 mm. Additionally, you need to take into account the slope of the slope and the features of the sheathing.

To ensure that the work of constructing a roof from corrugated sheets with your own hands is completed as quickly as possible and with the least amount of labor, it is recommended to prepare in advance everything necessary for the work.

1. Screwdriver.
2. Special riveting machine. With its help you will process the joints of sheets of material.
3. Tool for manual cutting sheets. It will be discussed in detail below.
4. Building level.
5. Yardstick.
6. Hammer, pencil, nails and other small things used to perform any construction tasks.

It is important to prepare thoroughly for installation work so that everything goes smoothly top level and with minimal costs. To begin with, you should properly organize the transportation of roofing material to the workplace. Lift each sheet onto the roof individually.

It is important that the street is not gusty and strong wind, because it may cause damage to the material.

The main stage of preparation begins with the organization of insulation, laying moisture and vapor barriers. The latter is attached to inner side rafters with an overlap of about 10 cm. The joints are glued with metallized tape.

Check the film before use. Any defects, cracks or other damage are unacceptable. They must be sealed. Remember that properly installed vapor barrier, insulation and moisture protection can save up to 20% of heat and even more.

When using corrugated sheets, it is best to insulate the roof using matte materials. No special recommendations for thermal insulation are given: the slabs are laid in a sheathing, previously covered with a vapor barrier film, and covered with a layer of waterproofing.

Pay special attention to waterproofing. This material will protect the insulation from the harmful effects of moisture, upon contact with which the thermal insulation properties are noticeably reduced. As a result, this leads to the roof becoming covered with ice, the rooms becoming damp, wooden structures quickly rot, etc. Does a great job of protecting against moisture polyethylene film. Lay it with an overlap of about 15 cm and secure the joints with adhesive tape.

The corrugated sheet is laid starting from the lower edge of the roof. The material is installed with an overlap. The sheets are fastened using self-tapping screws rubber seals. They must be fixed in the bends of the corrugated sheet waves.

First of all, it is necessary to make a dense plank flooring under the valley plank. Place it approximately level roofing sheathing, retreating about 60 cm from the groove on both sides. Laying the bottom valley boards should be done with an overlap of at least 20 cm. Use nails to secure the bottom strip. Finally, it is fixed together with the roof. If the roof has a gentle slope, experts advise additionally using mastics for compaction.

Place the bottom strip under the roof ridge approximately 25 cm. Place a sealant between the strip and the profiled sheet. It is recommended to fasten the end boards above the sheathing. In the future, this will make it possible to secure the end strips. It is in this order that the wind corner is created.

On next stage The cornice strip is installed and hemmed with a profiled sheet. This bar must be set lower in relation to the profiled sheet. Be sure to take care to create proper ventilation of the space under the roof.

The procedure for laying corrugated sheets is largely determined by the characteristics of a particular type of roof. For example, if we're talking about O flat structures, then the sheets are stacked with overlap in 1 wave and the mandatory use of longitudinal sealing gasket. In the case of steep slopes There is no need to install sealant. When finishing hip roofs laying the corrugated sheet begins directly with hip center. The sheets of roofing material are directly aligned with a rope pre-stretched along the eaves.

There are several technologies for laying modern profiled sheets on the roof. For example, in accordance with the vertical installation method, the first sheet is laid at the bottom to create a temporary fastening. The 1st sheet of the 2nd row is mounted using a similar principle. Next, the 2nd sheet of both rows of masonry is fixed so that the result is a block of 3 profiled sheets. Then you need to dock the next one to the laid block and continue to do so until all the allocated space is filled.

Laying can also be done by creating blocks of 3 profiled sheets. To implement this task, you first need to lay 2 sheets of the 1st row, fastening them to each other as securely as possible, and then dock the 3rd profiled sheet of the 2nd row. The laid block is secured after precise alignment in accordance with the cornice. Afterwards, the next block of the same type is created, and the laying continues according to this pattern until the end.

Regardless of the chosen method of installing the corrugated sheet, be sure to check each fixation unit. The reliability, service life and quality of the future roofing covering as a whole largely depend on the connection points.

Rules for installing planks

Making a roof from the material in question with your own hands requires the mandatory use of different slats. The first of them is the end one. As a rule, it has a two-meter length. If it is necessary to increase the length of the planks, they are overlapped. Mounted along the roof overhang in the direction of the ridge. The fastening is carried out in such a way that at least one wave of the profiled sheet overlaps the end strip. Use self-tapping screws for fixation. They must be fastened in increments of no more than 100 cm.

The next step is arranging the ridge. When performing this stage of work, you need to be as careful as possible, because... the ridge is one of the most important nodes roofing system. Installation is carried out using smooth ridge components, between which professional builders it is recommended to lay a layer of additional thermal insulation. In the case of using corrugated profiled sheets, installation of a special ridge seal is allowed.

Work on installing a roof made of corrugated sheets is completed with the installation of abutment strips. These products are two meters long and are laid with an overlap of up to 20 cm. They are fastened with self-tapping screws on the side of the profiled sheets. Self-tapping screws must be installed every 40 cm.

It is important to follow the rules for connecting the roof structure to the wall of the house. Thus, the end of the roof and the walls are connected using a special ridge seal. It is placed between the joint strip and the upper edge of the profiled sheet.

It is important to lay a longitudinal seal at the lateral junctions of the roof. Such an event will help protect the structure from snow and other undesirable elements getting into it. If the roof slope has a steep slope, there is no need to use a sealant.

In the process of constructing a roof from a corrugated sheet with your own hands, there is almost always a need to cut the sheets. This can be done using a variety of tools. The most important thing is that during such processing the protective layer of the sheet is not damaged.

For cutting, a hacksaw for metal, ordinary scissors for cutting tin, Circular Saw, professional electric cutter. You should avoid using grinders and other abrasive tools. After cutting with a grinder, the corrugated sheet material will become very brittle and unstable to corrosion, which as a result will not in the best possible way will affect the main characteristics and service life of the roofing system.

After cutting with any suitable tool The edges of the corrugated sheet must be coated with enamel designed specifically for processing polymer surfaces. Thanks to this, the protection of the corrugated sheet from corrosion will be restored.

You are already familiar with the main aspects of constructing a roof made of corrugated sheets with your own hands. Now you need to understand and learn a number of nuances that will allow you to complete the work at the highest level.

First of all, remember that the corrugated sheet is laid starting from the end of some lower corner. In some situations, you can fasten several sheets at once at the bottom, stepping back from the cornice strip about 40 cm. Fastenings must be made on every 2nd wave.

Special wind corners are designed to protect the end boards. They need to be installed after all the sheets have been laid. Profiled sheets are laid transversely and longitudinally.

In the case of horizontal fastening, the overlap is made such that the top sheet overlaps the bottom sheet by exactly 1 wave. This is relevant for situations where installation is carried out using a special rubber gasket. In the absence of such a gasket, the overlap should be 2 waves. If the profiled sheet is laid vertically, the upper element must overlap the underlying one by at least 20 cm.

The use of the repeatedly mentioned seal can be abandoned only if the roof slope has a slope exceeding 60 degrees. After laying all the corrugated sheets, proceed to forming connections. Longitudinal joints are made along the ridge every 50 cm, vertical connections– along the bottom of each existing wave.

To install the roofing material in question, you can use only self-tapping screws specially designed for this purpose. They are also known as hardware. Approximately 5-8 such fasteners should be used per 1 m2 of roof space. It is recommended to match the hardware to the color of the roofing. On the ridge, fastening is carried out with the obligatory use of a tin gasket. On the main field, you need to use a rubber pad.

Thus, independent device Roofs made of corrugated sheets are quite possible. You just need to follow all the rules and adhere to the basic recommendations, thanks to which even an inexperienced House master can understand the procedure for attaching profiled sheets and performing all related operations. Follow the instructions received and you will succeed.

Good luck!

Video - Do-it-yourself roof made of corrugated sheets

Profiled sheet (corrugated sheet) is made of steel sheet coated with zinc, aluminum and protective polymers. Widely used in construction in the form of roofing material, for the construction of gates, fences and other structures.

The material acquires corrugation when passing through roll forming machine, while the edges of the sheet can be in the form of a wave or in the shape of a trapezoid. The width of the corrugated sheet is 113-120 cm, length 30-1200 cm, thickness 0.4-1.2 mm.

Advantages of corrugated sheets

Before we move on to installing a profile sheet roof, let’s consider the advantages of the material:

• Not subject to corrosion;
• Long service life;
• Ecologically pure;
• Variety of colors and shapes;
• High resistance to environmental influences and mechanical loads;
• During installation, a minimum number of joints are formed;
• Universal.

Disadvantages include the formation of condensation and low sound insulation.

Corrugated sheet overlap and roof angle

If corrugated sheeting is used as a roofing material, the sheets must be installed with an overlap.

• If the slope exceeds 30°, the sheet overlap will be 10-15 cm;
• 15°-30° – 15-20 cm;
• less than 15° – up to 20 cm.

Calculation of roofing material

To correctly calculate the roofing material, you first need to calculate the roof area, taking into account design features. To do this, the surface is divided into geometric figures, all data is subsequently added up.
Each type of roof shape (triangle, trapezoid or square) uses its own formula to calculate the area. Eaves, end overhangs and bends (ridges, ridges and abutments) are measured. Corrugated sheeting has two widths: total width – 118 cm, and working width – 110 cm; this fact also needs to be taken into account when calculating.

To calculate the required number of sheets running horizontally, you need to divide the length of the ramp by dividing the working width. The size of the overlap is also taken into account. The number and length of sheets is equal to the sum of the overhang from the cornice, the overlap and the length of the slope.
2 meters is standard length additional element, to determine the required amount of material, we sum up the length of the slopes, and then, taking into account the 10 cm of overlap, divide the resulting figure by 1.9. To fasten the corrugated sheeting, self-tapping screws with rubberized gaskets are used, their number is 8 pieces per 1 m2. At the last stage, we determine the amount of insulation and waterproofing.

Roofing installation from corrugated sheets

Thermal insulation, vapor barrier and waterproofing indicators in a roof structure largely depend on the correct installation of the “pie”. The entire roof structure is called a roofing “pie”. The system may be different, depending on the room: whether it will be residential or not.
Pie device:

• Profiled sheeting;
• Lining or drywall;
• Insulation;
• Vapor-proof material;
• Lathing;
• Rafter leg;
• Ridge seal;
• Skate and rail;
• Rafter strip;
• Waterproofing film.

The first sign of damage to the roofing “pie” will be the formation of ice at sub-zero temperatures.

Tools and material for installing corrugated sheets

• Film or thick polyethylene;
• Stapler;
• Glass wool or mineral wool;
• Silicone;
• For gluing waterproofing seams, connecting tape;
• For waterproofing, membrane in rolls;
• Paralysis film;
• Self-tapping screws;
• Screwdriver;
• Beam;
• Lining.

List required quantity building materials are compiled when calculating the estimate, and will depend on the type of roof structure.

Correctly covering the roof with corrugated sheets with your own hands

At the first stage of installation work, waterproofing is laid, starting from the lower edge of the sheathing. The film is laid with an overlap of 10 cm to 15 cm. The material should not be stretched too much, and a construction stapler is used to fasten it.

Installation of counter-lattice

It is necessary to leave a gap between the waterproofing and the corrugated sheet to drain moisture. The counter-lattice is installed afterward; the structure consists of planks 5 cm high, they are placed along the sheathing, parallel to the cornice and rafters.

Installation of corrugated sheets

To ensure that the mounting hole is tightly closed, use self-tapping screws with sealing gaskets. Silicone sealant The horizontal overlap of the corrugated sheet is processed.

If the installation takes place in a flat roof, then the sheets are installed with a vertical overlap in two waves. If a sealing gasket is used, the sheets may be installed with an overlap in one wave.
Installation of corrugated sheeting on a gable roof occurs from the bottom row. Place 5 sheets and fix them in the center with a self-tapping screw. And then, in increments of 50 cm, the corrugated sheets are connected to each other with self-tapping screws. If everything is aligned along the overhang, then final fixation is made.

Installation of end strips

The end strip for most sheets is 2 m; installation begins at the bottom with an overlap of 5-10 cm. When correct installation at least one wave of the corrugated sheet will overlap. In increments of up to 1 meter, fastening occurs with self-tapping screws.

The ridge strip with an overlap of 10 cm is fastened using smooth elements; they must be included in the kit. It is advisable to install a layer of breathable seal between the corrugated sheets; fastening occurs in increments of 30 cm using roofing screws.

Installation of the junction strip

The abutment strip is laid with an overlap of 20 cm, fastening occurs with self-tapping screws in increments of 40 cm. Using a ridge seal, the connections between the ends of the wall and the roof are sealed, this will help prevent moisture from getting into the cracks.

• The roofing process is considered high-altitude work, and before starting installation you need to take safety measures;
• During installation, it is better to lay corrugated sheets on boards rather than on the ground;
• The corrugated sheeting should go down from the eaves by about 5 cm;
• The waterproofing should sag a little.
• Use a taut string to lay the profile sheets evenly along the cornice.
