Profiled over. How to cover the roof with a profiled sheet: step by step instructions, processing nodes. Installation of end strips

Comfortable and cozy living can be provided only by high-quality roofing material, which will protect the roof from leaks, and the entire structure from destruction.

In terms of strength and durability, steel is the leader among roofing materials, but this material has a significant weight. Under the influence of a heavy coating, the truss system can weaken and deform. The method of corrugating steel sheets helped to solve the problem. As a result, even sheets of large size began to have a small weight. At the same time, the strength characteristics and stiffness of the material remained unchanged due to the formation of a trapezoidal profile. Such material became known as corrugated board.

Practicality in use, as well as minimal harm environment in a short time made corrugated board a very popular material.

The main characteristics of corrugated board

Profiled sheets are obtained by cold rolling hot-dip galvanized steel. During the manufacturing process, the material is treated with protective agents in several layers, thereby increasing the strength and durability of finished products. First, an anti-corrosion phosphate is applied to the steel sheet, then the surface is primed. After that, a polymer mixture is applied to the front part, and the lower part of the sheet is covered with a special varnish.

The result of the actions performed is a high quality material with a long service life. High-quality corrugated board has a large number of advantages, but also negative sides he has.

Among the positive characteristics of this coating, the following can be distinguished:

Long operating period.
A price that beats most competitors.
Minor weight.
Easy assembly and dismantling in a short period of time.
Resistant to sudden temperature changes.

The disadvantages of the profiled sheet include poor noise absorption, which to some extent worsens the sound insulation.

Material classification

Decking is widely used not only as a roofing material.

Before installing corrugated board on the roof, you should familiarize yourself with its classification:

H is the best roofing material for covering surfaces and ceilings. Can be used as fixed formwork. The strength and reliability of the material is ensured by additional stiffeners, a special thickness and height of the profile.
C - material used mainly for the construction of fences. The cost of such a coating is slightly cheaper, but the quality characteristics are in many ways inferior.
HC - is considered a combined material that can be used as roofing but with extreme caution. First, the roof should not be subjected to significant loads. Secondly, the slope must have a good slope. Only in this case can fatal consequences be avoided during operation.

Determining the angle of the roof

In order to correctly install the corrugated board on the roof, it is necessary to determine the angle of inclination of the roof. The value of the overlap on the adjacent sheet depends on its value:

Laying sheets on a roof with a slope of 12 to 15 degrees is carried out with an overlap of 20 cm.
With a slope of 15 to 30 degrees, the overlap should be 15-20 cm.
Increasing the angle of inclination to 30 degrees reduces the overlap of sheets to 10-15 cm.

The laying of corrugated board on a roof with a slope of less than 12 degrees should be accompanied by additional sealing of the joints with silicone sealant.

Installation of corrugated roofing

Run quality installation professional sheet on the roof helps instructions from experienced builders.

Material transport

It is necessary to transport corrugated board on a flat surface in order to prevent strong kinks.

When unloading mechanically, soft slings should be used, manual unloading involves the presence of one worker for every 2 meters of length.

The rise to the roof is carried out by means of a log.

Preparatory stage

The installation of a profiled sheet on the roof begins only after the calculation of the material and the determination of its type. Managers of a company engaged in the production and sale of corrugated board can competently perform such actions. In addition, you need to prepare a set of tools for work, consisting of a tape measure, a hammer, a hacksaw for cutting metal, a drill and a cord.

Ventilation and waterproofing

One of the steps in solving the problem of how to properly mount corrugated roofing is to perform work on effective vapor barrier, thermal insulation and ventilation. This prevents the accumulation of moisture in the under-roof space, which causes the destruction of many materials.

Waterproofing materials are laid on the crate directly under the sheets of corrugated board. Waterproofing is carried out according to special rules: the material must hang down by about 2 cm, the strips must overlap up to 15 cm, the joints are sealed with adhesive tape.

Maximum air circulation is achieved by creating ventilation holes between the ridge strip and the roofing material. To create additional channels for air movement, place on top of the waterproofing wooden slats.

Installation of rafters and battens

On top of the waterproofing layer, rafters or steel girders are fastened (with a profile height of 4 cm). A crate is hammered onto these elements, which has a longitudinal direction. The step of the lathing is selected depending on the type of roofing material.

The crate can be made from a bar with a section of 5 * 5 cm, boards 3 * 1 cm or moisture-resistant plywood 1 cm thick.

The crate can be continuous and thinned out. The use of the first type will be more effective on the ribs, along the ridge and around chimney. In other cases, it is allowed to pin the elements in increments of 5 cm, and the distance should be the same over the entire area.

Before mounting the profiled sheet on the roof, wood elements must be treated with antiseptics and flame retardants without fail.

To prevent the formation of condensate, you can use a diffusion gasket, which is attached with small nails directly to the crate.

The device of the crate is a very crucial moment, on which the strength and reliability of the roof and the entire structure depend.

Formation of the cornice overhang

The cornice overhang is formed during the laying of the bottom row of corrugated board, but you must first install the cornice strip, which is located below the waterproofing. This design directs condensate and wastewater into the chute and then into drainpipe. Neglecting this rule will lead to the fact that water will fall on the walls of the house. The consequences of this are known to all.

How to mount corrugated board - technology

Proper installation of corrugated roofing is possible only if certain instructions are followed. The time-tested technology of installing a roof from a profiled sheet will allow you to build a reliable roof.

Sheet cutting

Cutting corrugated board significantly increases the consumption of material and its quality characteristics, so you should buy a coating in accordance with the dimensions of the slope. However, this ideal situation is not always obtained, therefore, it is necessary to know the rules for cutting metal sheets, as well as the tools for performing these actions.

Before you install the corrugated board on the roof, you need to measure it on a flat and even surface, for example, laying it on the ground.

cutting material a variety of tools, but a more efficient and high-quality result is obtained when using electric drill equipped with a disk attachment. From hand tools, scissors for cutting metal or a hacksaw with fine teeth are suitable.

It is not recommended to use a grinder or other devices with abrasive cutting discs for this purpose. The operation of such tools is accompanied by the release of a large amount of thermal energy, which can cause a decrease in the performance of the material.

The cut edge is subject to mandatory treatment with protective equipment, the most in a simple way is an regular paint, matched to the color of the corrugated board.

Transporting sheets to the roof

Some sheets of corrugated board are quite large, which makes it difficult to lift them to the installation site. In addition, in this situation there is a risk of damage or deformation of products.

To make the transportation of sheets to the roof more comfortable, it is necessary to use logs. These devices rest against the ground at one end, and against the eaves of the ramp with the other. The distance between the lags should not exceed the width of the sheet of roofing material. Such a device allows two builders to lift overall sheets onto the roof.

Fixing sheets on the crate

The technology of fastening corrugated board on the roof implies the following rules:

As fasteners, it is best to use hexagonal self-tapping screws having a length of 8 cm and equipped with a sealing gasket. When tightening the self-tapping screws, you should not make great efforts, since as a result of this the gasket may become more dense, which negatively affects the waterproofing layer.
During normal installation, fasteners are placed in the lower wave of the profiled sheet, but at the ridge or at the junction of the sheets it is better to fix the material in the upper wave.
The laying of the first sheet starts from the end of the slope, the second and subsequent sheets are laid with a side overlap up to half a wave. If the roof has a gentle slope, then the overlap should be 1.5 waves.
Additional sealing is recommended at the joints. For this purpose, you can use bituminous mastic or self-adhesive tape.

Making a gable cut

Of great importance in solving the problem of how to properly install corrugated roofing is given to the installation of wind battens and strips that will protect the roof and corrugated board from moisture and wind. It is these factors that can cause the destruction of the entire structure.

If the corrugated board was laid in the frontal part with an allowance of up to 5-7 cm, then a wind rail can be used for protection. This element has a size of 2.5 * 8 cm, and its fastening is carried out using self-tapping screws. Laying sheets without allowance from the side of the gable should additionally be accompanied by the installation of a wind bar. These elements overlap up to 15 cm and are fixed with self-tapping screws every 20-30 cm.

If the slope has a longitudinal or transverse interface with the wall, then use the corner strips. Such parts are also installed with an overlap, which can be more than 10 cm. Fasteners are placed at a distance of 20-30 cm from each other.

Mounting the ridge and snow guards

It is recommended to arrange the ridge part of the roof from the edge on which wind loads have less effect. The profile of the ridge is selected depending on the preferences and taste of the developer, simple, figured or tiled. Self-tapping screws are used to fasten the ridge, placing them at a distance of 20-30 cm from each other. In addition, be sure to use a sealing gasket and leave a ventilation gap.

Snow retainers are necessary so that during a heavy snowfall or thaw, snow avalanches do not roll off the metal roof. At the same time, the installation of snow retainers on the roof of corrugated board must be carried out according to certain rules. These elements are installed at the bottom of the slope perpendicular to its direction. For fastening, you must first mount the bars.

Thermal insulation of the roof from the profiled sheet

In order for the question of how to properly mount the corrugated board to have a complete solution, the structure must be insulated. Mineral wool and a vapor barrier are used as insulation for corrugated roofs, these materials are considered the most effective.

Thermal insulation material can be taken in rolls or mats, the quality and performance characteristics do not change from this. The gaps between the rafters are filled with insulation, using screws, adhesive or a thick thread for fastening. Fixation process thermal insulation material should be controlled to avoid strong compression. After all, the main function is performed not by cotton wool, but by the air located inside the material.

Thermal insulation must be covered with a vapor barrier, it will protect the insulation from the penetration of moisture, which rises along with warm air. Getting inside the heat-insulating material, moisture reduces its performance.

When insulating the roof, it is worth taking care of ventilation. To do this, the triangle at the top of the roof is left without insulation. It is in this place that conditions are created for free air circulation.

In some situations, you can proceed as follows: lay the flooring from the profiled sheet on old roof. This helps to improve the thermal insulation characteristics of the roof, but on condition that the performance properties of the old layer meet all the requirements.

Sheet roof maintenance

The corrugated board does not require special care, but care must be taken during the installation process so as not to harm the material. In addition, it is necessary to store profiled sheets until the moment of laying in upright position. It is best to make a lining of boards spaced in half a meter increments.

If damage to the protective layer could not be avoided, then the damage site can be covered with paint to match the material.

For a comfortable stay in the house, it is important to make a high-quality and reliable roof with good coverage. To date, one of the best roofing is corrugated board. It reliably protects the roof from leaks, collapses, provides tightness in the under-roof space. And the most important thing is that it is environmentally friendly. However, the correctness of the installation work. Only in this case, the corrugated roofing will serve you for many years. This article will provide detailed instructions on how to cover the roof with corrugated board with your own hands, as well as video and photo materials.

As mentioned at the beginning of this article, corrugated board has a lot of advantages, which makes it an indispensable roofing material. You can also note other positive aspects of this material:

The profiled structure of the sheet has a high bearing capacity.
The lightness of the material greatly simplifies the work with it.
After laying the sheets on the roof, no joints are formed. This ensures the tightness of the coating.
Due to the special polymer coating, the material does not corrode, and as a result, its service life increases.

Note! Laying corrugated board on the roof should not cause any special problems, and at first glance, everything may seem extremely simple. However, during installation work, no flaws and inaccuracies should be allowed.

For the transportation of corrugated board, specialized transport is required. Sheets must only be laid horizontally. It is also recommended to tighten them with slings, after laying them on a hard and even surface. There are also special requirements for the driver. It is necessary to drive the car without sudden braking and turns. Failure to do so may result in damage to the material on the way to its destination.

In addition, it is important to ensure high-quality storage of corrugated board. The base must also be level and firm. If it's time to lift the sheets to the roof, then you need to do this with the help of a log. Their length should correspond to the height of the roof from the ground. You can lift several sheets at once.

Note! If the weather is windy, then it is impossible to lift the sheets onto the roof.

Today, such types of corrugated boards are known:

Mark C. The canvas has a sinusoidal or trapezoidal shape. If you decide to do decorative trim roofs, then this option is just the way.
RS brand. It is used both for laying on a roof, and on walls.
Mark N. This model is equipped with additional stiffening ribs.

It is very important to know what slope angle is allowed for a particular product. Each manufacturer develops individual instructions. Therefore, when buying, you should ask for instructions, which is called the so-called "Installation of the roof from corrugated board instructions." Based on this, it is important to consider the future slope of the roof. Knowing the slope will help you calculate how much overlap each sheet should have. Below are some calculation options:

A slope of less than 15° will provide an overlap of 200 mm or more.
A slope of 15 to 30 ° will provide 150–200 mm and no more.
If the slope is less than 12 ° or the roof is flat, then each seam and joint should be carefully sealed. Otherwise, the roof will not cope with its functional responsibilities.

Payment

Before buying material, it is important to calculate the number of sheets. This requires information regarding the width and length of the slope, as well as what brand of corrugated board will be used. To calculate, you can use a special program or draw a roof on a reduced scale. This will help you practically accurate calculations. It should not be forgotten that the sheets are overlapped. Depending on the angle of the slope and the grade of the profiled sheet, the overlap will differ. So you will find out how much the length and width of the sheet will be “eaten up”. Moreover, do not forget to add an overhang to the cornice, which can be up to 30 cm.

Note! It is necessary to purchase all additional elements in advance, for example, valleys and slats. They will be fixed in places where the slope has a certain kink, from the end, on the ridge and in other similar places.

Each sheet is attached to the crate with self-tapping screws. This is the only way to ensure reliable coverage. Fasteners are subject to special requirements. So, they must be made of galvanized steel. In this case, each self-tapping screw must have a special gasket made of elastomer or neopreon rubber. This rubber will provide a hermetic docking of the self-tapping screw with the profiled sheet. Due to this, moisture will not penetrate the wooden elements of the roof, which means that rotting of the supporting structure will be prevented.

The following technical parameters are presented for self-tapping screws:

Size 4.8x32mm, 4.8x60mm and 4.8x80mm.
The presence on the cap of a protective and decorative coating in the form of powder paint and a layer thickness of 50 microns.
The surface is treated with electrolytic galvanization with a thickness of 12 microns.
The presence of a protective gasket made of elastomer for profiled sheets and for valleys made of aluminum sheet.
Self-tapping screws should contain stabilizers that do not allow the negative effects of ultraviolet rays.

Note! When buying coating sheets, purchase one color and self-tapping screws. This will give the aesthetics of the entire roof.

It should also be mentioned about special seals, which are made of foamed polyethylene and polyurethane foam. The sealant is placed between the sheet and the crate. It is believed that a strip seal with a rectangular cross section is universal. But it will be much more effective to use those seals that repeat the shape of the profiled sheet.

The presence of a seal reduces noise metal roof, increases the quality of the thermal insulation of the cake and increases the service life. A special adhesive is applied to the strips of the seal on both sides, so its installation is greatly simplified. It is very important that the sealant be perforated for ventilation in the under-roof space.

Note! The presence of a seal eliminates large gaps formed as a result of adhering to roof structure sheet. Birds, insects and cold air often get into these gaps. The special properties of the sealant material make it bioresistant and moisture resistant.

Immediately before the installation of profiled sheets, hydro and vapor barrier is laid. To make a vapor barrier, you can purchase a special film or roofing material, in extreme cases. The vapor barrier is attached to the crate. It is recommended to lay it from the lower edge of the roof. Due to this, each subsequent layer will be lower and moisture will not penetrate to the wood.

Note! If the brand of corrugated board S-8, S-10 or S-20 up to 0.5 mm thick is used, then the crate must be continuous. In all other cases, the step of the crate is selected individually from the characteristics of the roof.

Separately, it is worth mentioning about the layer of insulation, which will save 25% of heat. Those roofs on which corrugated board is mounted are advised to use matte insulation. The result is a roofing cake:

A layer of vapor barrier film.
Insulation.
The final waterproofing layer.

When making this “pie”, a “cold triangle” should be organized. Its presence will ensure a good passage of warm and cold air through the cracks in the cornice and ridge. So, natural ventilation will be created, which will prevent the formation of condensate.

The laid waterproofing layer will retain all the properties of the insulation. Otherwise, with strong moisture on the roof, an ice crust, dampness will form and, as a result, the process of wood decay is inevitable. For this reason, the material for each layer of the cake must be chosen carefully. It must be of high quality.

In order for all the work to go smoothly and without failures, take care of the availability of the necessary tools in advance:

rope;
roulette;
screwdriver;
hammer;
metal scissors;
construction gun with sealant;
marker or pencils;
construction stapler;
drill.

Note! Profiled sheets are cut cold, as polymer coating not resistant to high temperatures. It is better to use scissors for metal or a jigsaw. At the same time, treat each cut with an anti-corrosion primer. This will increase the life of the coating.

Laying scheme

The sheets are overlapped on the lower edge of the roof, and the screws are twisted into the bend of the wave. Compliance with a specific installation scheme will create a reliable roof. First of all, under the valley plank at the level of the crate, a dense flooring is made from the groove at a distance of 60 cm from both sides. The lower boards of the valley are mounted with an overlap of 20 cm. The bottom plank is fixed from the edges with nails, and the final fastening is carried out together with the roof. If the slope is gentle, then sealing mastics should be used here.

Under the ridge, the bottom bar is wound up by 25 cm. A profiled or universal seal should be laid between the profiled sheet and it. As for the installation of end boards, it is better to fix them above the crate, then it will be possible to fix the end plate. This structure will be called the wind corner. After that, it is installed eaves plank and lining with corrugated board. It is mounted below the profiled sheet.

Installation of sheets will depend entirely on the type of roof. For example, if the slope is gentle, then a longitudinal seal is used and overlapped by one wave. If the slope is a steep compactor, it is not necessary to use.

Note! If you have a hip roof, then the installation begins with the hip itself. A cord is stretched along the cornice and each subsequent sheet is aligned along it. It is unacceptable to do this at the end of the ramp.

There are two methods for laying sheets of corrugated board on the roof:

Vertical direction. In this case, the first sheet with temporary fastening is laid below. Similarly, the sheet is mounted on the second row. Next, two sheets are stacked side by side, a square of 4 sheets is obtained. More sheets are stacked to it and so on. This method is in particular demand if the roof is equipped with a drainage groove.
Another method of stacking sheets is to make a block of 3 sheets. First of all, 2 sheets are laid on the first row. Between themselves, they are securely fixed, and the 3rd sheet of the 2nd row is joined last. This block can be fixed while aligning with the eaves.

Note! No matter which sheeting method you choose, it is important to pay attention to Special attention each docking point. It is on this that the reliability and quality of the roofing will depend.

For each sheet of corrugated board, 7-8 self-tapping screws are required. They need to be twisted into the bottom wave. As mentioned above, the material is overlapped both vertically and horizontally. The overlap will depend on the angle of the slope. From what place should the sheets be laid? If the roof slope has a rectangular shape, then it is possible from any end along the cornice line. If the shape is a trapezoid and a triangle, then first of all it is important to think over the laying scheme. However, the first sheet is mounted in the center, and then the sheets are stacked symmetrically on both sides.

If a drainage system is planned, then the corrugated board is mounted along the eaves with an overhang of 60 cm. If it is not, then the overhang is carried out according to the material grade:

NS-20 - up to 10 cm.
S-44 and NS-35 - up to 30 cm.

So, align the first sheet along the cornice and the end of the roof. After that, it is fixed with a self-tapping screw at the top. Each next sheet is fastened along the longitudinal side of the sheet. It is pre-aligned with the eaves, and then fastened with the crate. According to this scheme, row after row is assembled.

The installation of the material is carried out so that a frontal overhang 7 cm wide is formed. At the cornice, the sheet is fixed at a distance of 30–40 cm, and the remaining rows of self-tapping screws can be staggered in increments of 1 m. . On a longitudinal overlap, fasteners are located at the top of the profile at a distance of 300 to 500 mm.

The next step is to install the ridge and the end plate. According to the standard, the end plate is 2 m long. If the length is not enough, then it overlaps. The fastening of the strap is carried out from the roof overhang to the ridge.

Note! When mounting the end strip, make sure that it overlaps at least one wave of the sheet. Self-tapping screws are twisted in steps of 1 m to the profiled sheet.

After that, it remains to make the last node of the roof - the ridge. Only smooth ridge elements should be used here. A number of experts recommend laying a special ventilated seal between them. If the sheets are corrugated, then a ridge seal is used.

At the end of the roofing work, a junction bar is installed with profiled sheets. They are an element with a length of 2 m. They overlap up to 20 cm. Fasteners are made with self-tapping screws from the side of the roofing sheets. Mounting pitch 40 cm.

Note! When organizing the adjoining of the roof to the wall, a special sealant should be used. It is laid between the joint strip and the upper edge of the corrugated board.

To prevent snow and rain from getting into the cracks, a longitudinal seal is also laid to the side junction. If the roof is steep, then such a seal is not needed.

In conclusion, let's summarize:

It is very important to pay attention to the transportation of roofing material.
The sharp edges of the sheets can cut your hands, so you need to work with protective gloves.
It is necessary for three people to lift the sheets to the roof. It uses two guides.
The installer must wear shoes with soft soles so as not to scratch the surface of the sheets.
If the surface is accidentally scratched, then these places must be treated with paint for polymer coatings.
You can step on the sheets only in places of the crate.

So, we are convinced that the corrugated board is excellent material for roof decking. However, it is important to remember that it can serve for a long time and with high quality only if the installation and calculation technology is observed. if you have own experience in this construction industry, then write comments at the end of this article. It will be equally useful to pay attention to the photos below. On them you can consider the intricacies of performing work on overlapping the roof with profiled sheets.

Schemes

Below is a series of photographs and tables from which you can get the details of installing corrugated roofing:

The builder takes care of some of the work. Roofing works are responsible, but not difficult. To cover the roof of the roof with a professional sheet with your own hands is a feasible task for a craftsman. You just need to follow the sequence of actions and follow simple rules.

Roofing from corrugated board, instructions for the selection of material

The professional flooring is durable, convenient in work. Suitable for flat, steep slopes, roofs of complex shape. Sheets 1.5–12 m long with a size gradation of 0.5 m and a working width of 0.8–1.2 m are formed with depressions in the form of a trapezoid, waves. Manufacturers rely on the GOST 24045-2010 regulation on profile sheet products with trapezoidal corrugations.

The purpose of the material is determined technical properties by letter indexing:

H (bearing) - differs in the height of the corrugations 45–160 mm, sheet thickness, reinforced with additional longitudinal ribbing, withstands extreme loads;
NS, PK (universal, roofing) - profiled grooves along the shelves allow you to withstand snow and wind loads without restrictions on the roof windage, height 20–45 mm;
C (wall) - used with restrictions: the height of the shelves is taken at least 20 mm, the crate becomes more frequent or continuous.

The choice of roofing of this type is stimulated by the advantages:

long service life with minimal maintenance;
the polymer coating serves up to 50 years, the warranty period is up to 20 years.
strength with low weight;
the breadth of the color palette;
the availability of do-it-yourself roofing roofing with a professional sheet.

Of the shortcomings, the drum effect was recognized as significant - the transmission of the sound of falling drops with possible amplification. Laying a layer of insulation eliminates the resonance defect.

Roofing from corrugated board, technology

We select the corrugated sheet, the reference point is the steepness of the angle of the rafters. Do-it-yourself roofing with a professional sheet gives scope for the selection of material. It is used as a roofing and wall profile with a corrugation height of at least 20 mm. And on the canopies above the porch, a flat covering of utility blocks is acceptable smaller.

In order to reduce the cost of construction, a combination of roofing and wall profiled sheets with the same corrugation width is allowed. In areas with a change in geometry in the direction of decreasing the angle, a mismatch in the height of the profile is allowed. How to cover the roof - the developer decides.

Scratches, other damage to the anti-corrosion coating are treated with a protective coating immediately, at the storage stage

The general requirement is to limit the reduction of the angle. For flat roofs for auxiliary buildings, the angle reduction limit is 8 °, for residential buildings - 10 ° with a continuous plank sheathing or OSB sheets.

The crate is discharged from an angle exceeding 15 °. Discharge step:

S-20 - 0.2–0.3 m;
S-21 - 0.3–0.5 m;
NS-35, S-44 - 0.5 m up to 15 °, more than 15 ° - up to 1 m; permissible load 0.43–0.76 t per m 2.

Key knots of a roof from a professional flooring

The rafters rested securely on the Mauerlat, but the installation will wait until the steam-conducting membrane is laid and glued. Dehumidification will extend the life of the insulation, the film will not allow the draft to blow out small fractions of the warming cake from.

A counter-lattice is attached to the nails over the membrane. The purpose of the timber 20–40x50 is to create a ventilation gap for ventilation of the insulation and roofing. In frost and heat, the breeze will reach for the ridge. There will be no condensation on the inside of the sheets. The LSTK metal profile is not widely used in private construction. The technology of work is identical, therefore, the type of material is not distinguished separately.

Wooden parts are nailed. Fastening of OSB boards is permissible with self-tapping screws.

According to the tabular dimensions, the frequencies of laying the battens were determined, we nail unedged boards, slabs. The joints are arranged in the center of the beam of the counter-lattice. Mostly softwood lumber is purchased.

The installation of the 3 listed elements is carried out in stages from the bottom up, as shown in the photo. It is necessary to achieve the most even surface without sharp changes in height at the joints.

Aspen and are rejected - one is short-lived and weak: it will break under the foot during installation, the other is subject to excessive warping and twisting.

Fixing profiled sheet on the roof

We are preparing fasteners for corrugated board. You will need anodized metal screws with a drill at the end and pointed with fine threads. A rubber seal is required under the cap. It is easier to apply force to the hex head. The cross slot is harder to hit.

Average consumption - 7.5 pieces per 1 m 2. You will need self-tapping screws 4.8x30 for sheets and 4.8x50 (60) for additional elements. From the tool you will need with two batteries and a bat, an angle grinder with a 1 mm thick disc for cutting along the length, corners, flanging doborniks.

Connoisseurs argue: how to fix? A self-tapping screw in the bottom shelf holds the profiled sheet more securely. The top mount is safe in terms of leaks in roof space with stagnation of melt water on a gentle slope. Combinations with fastening are possible. Manufacturers insist on fastening in the first way: in deflection.

For a vertically fixed self-tapping screw, the sealing gasket evenly protrudes from under the head by 1 mm in a circle.

On the ridge and cornice, self-tapping screws are placed through the wave, in the middle of the sheet - in a run into each board of the crate. The joints of the sheets are fastened through 2 waves. Mark broken screws with beacons to close the hole without a long search.

Installation of a profiled sheet on the roof, instructions

How many vertical sheets are needed is up to the builder to decide. Ordering a full-size sheet without subsequent joints is economically justified. But you need to wait for delivery.

Sheets of standard length are stacked in two ways:

along the cord in order, starting from the bottom;
in an error-free way according to the scheme as in the photo.

The first sheets of corrugated board are attached to one screw in the middle. An overhang of 4–5 cm beyond the lowest point of the rafter is necessary to optimize natural ventilation and install a cornice. Then the set is fixed between each other after 0.5 m. After a control check of the evenness of laying along the roof overhang, the profiled sheets are finally fixed.

With a roof slope of less than 15° and a corrugation depth of less than 20 mm, the adjacent sheet is superimposed on 2 waves of the previous one. Increasing the angle allows you to block only 1 wave. If there is a drain groove in the bottom shelf, it should be blocked.

The top row overlaps the previous one. The amount of overlap relative to the steepness of the roof:

up to 15° - 200 mm;
up to 30° - 150 mm;
over 30° - 100–150 mm.

Even in soft shoes, you can’t step on the crest of the corrugated board - it will bend.

Making connections on the roof of corrugated board

Adjacency of corrugated board to the wall - prevents moisture from leaking, blowing snow under the corrugated board at the junction. The corner element is produced with a polymer coating, 2 m long, galvanized 2.5 m.

The junction bar for corrugated board is fixed through the upper wave. This is where the long fastener is needed. It is advisable to purchase full set components of the same manufacturer: at least there will be no difference in color.

It is difficult to connect to a pipe on a corrugated roof for the first time. The wings of the apron bypass the chimney are adjusted, tightly cover the pipe. The upper edge is pressed by tightening the screws into the dowels.

The adjacent profiled sheet will have to be reinstalled - forced manipulation in the name of preventing leakage. Without installing a porous sealant that copies the profile, this action will be a half measure. And indispensable sealing of the vertical seam.

The location of the pipe at the bottom of the roof dictates the need to install a snow stop.

Eaves roof overhang from corrugated board

Framing the lower overhang will prevent the wood from getting wet, the insulation from fraying, and will give a strict look to the structure. We present a choice of 3 equivalent design options for the overhang on the rafter legs.

Installation starts from the bottom of the wall. In the first two versions, the soffit as a frontal board is stiffer, not limited by vertical dimensions. Hex screws are not needed.

For completeness, it remains to install the end plate to protect the extreme rafters with going beyond the crest of the profiled sheet. Fastening to the rafter is carried out along the lower edge with an indent of 25 mm.

Skate on the roof of the profiled sheet

The gap of the upper edge of the intersection of the roof slopes is covered with a ridge bar. The shape of the ridge causes air circulation to ventilate the under-roof space.

Installation sequence:

according to the size of the shelf width (100–300 mm), double-sided tape is glued;
a porous seal is installed;
according to the marking, 50 mm is cut off from the support bar and the vertical stand, the upper bend is cut into the depth, the ends of the profile are bent at a right angle (or a standard plug is installed);
sealant is applied to the seal;
the skate is installed with an approach to the end bar;
fastening with screws.

The roof, mounted from a professional sheet with your own hands, has acquired the form of a single whole. Congratulations.

If your home needs a roof that has an attractive and sophisticated look at a relatively low cost, a corrugated roof — cold rolled galvanized steel sheet with color resin coating is what you need.

Advantages of profiled steel sheet:

excellent operational qualities: resistance to atmospheric factors, solar radiation, mechanical strength, resistance to corrosion,
short specific gravity(from 5.5 to 9.5 kg / m 2), therefore, low load on truss systems and crate
roofing material can be selected according to the texture and color for the design of the building,
relatively low price with high aesthetic qualities.

What kind of corrugated board is suitable for the roof

Any of the brands of corrugated board (universal, load-bearing or wall) is suitable for roofing, but laying thin wall material will require an almost continuous crate. For a regular crate with a step of 65-100 cm, it is preferable to use a more durable and rigid profiled sheet. The most commonly used material with such indicators:

brand H or HC (carrying and universal),
profiled 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 board depends on several indicators of the material.

What you need to cover the roof with corrugated board with your own hands

Single pitched or double pitched roof country house, a summer kitchen or a garage, it will not be difficult to cover it yourself with one or two assistants and some skills in working with a screwdriver and a jigsaw. A broken gable roof of a house with an attic will also be able to independent work. Help with this video.

If the roof frame is of a more complex configuration, experienced specialists should be invited to cover the roof with corrugated board. The price of work will depend on the complexity of the roof and the area of \u200b\u200bthe slopes.

How much material is needed

Calculate the amount of material for a lean-to or gable roof, knowing the size of the slopes, it will not be 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, the resulting number of sheets should be increased by 15%.

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

Tools and fasteners for work

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

Features of laying a roof from a profiled sheet

It is best to do the work with four people, it will turn out much faster. Two people can also cope, but it is very difficult to work with long sheets of corrugated board alone.

The minimum angle of the roof slope is 10 o. 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 less or more, the sheets will have to be cut.
To protect the corrugated board from corrosion, waterproofing and vapor barrier should be made along the crate.

Installation of the crate under the profiled sheets

An important stage in the installation of corrugated roofing is the organization of hydro and vapor barrier 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 crate and waterproofing (roofing material) on top of the crate under the corrugated board;
organization of a ventilated roof, creating a ventilated space between the waterproofing layer and the roofing material. To do this, false rafters from bars are installed along the rafter legs along the waterproofing, a crate is made along them, a puff cake will turn out: rafters, waterproofing, false rafters, crate, profiled sheet.

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

Lathing boards are laid in increments of 0.5-1.0 m, attaching them with nails or self-tapping screws to the rafters. The thicker and more durable corrugated board is used, the greater the distance between the boards of the crate. So, for example, for a profiled sheet of brand CH35, the crate step is 0.5-0.6 m, for CH44 - 0.65-0.75 m. The distance between the boards should not be more than 1 m.

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

The procedure for laying corrugated board with your own hands

Profiled sheets are laid from the bottom up, starting along the slope from the end of the building, from left to right or right to left - it all depends on which side of the sheet the manufacturer made the capillary groove. When laying the material, the groove must be closed by the wave of the next sheet.
The size of the overlap of profiled sheets horizontally and vertically depends on the angle of the roof slope. At small values of the angle of inclination of the slope, the sheets are laid with an overlap in two vertical waves, at 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 are working, lifting the sheets is easy. They are laid on a frame of 5-6 bars in packs of 5-10 pieces and are pulled up with a rope along inclined boards attached to the crate.

On the crate so that the sheets do not roll down, one or two bars are nailed from below and a pack of coating sheets is placed. It is much more convenient to work this way than to serve one at a time, although this method is also used.

How to fix corrugated board on the roof correctly

Sheets are attached to the crate with self-tapping screws with washers and sealing gaskets. Their number is no more than 6-10 pieces per 1 sq.m. flooring. On the slope, the screws are screwed into the lower, 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. On thick steel sheets in the places where they are attached to the crate, it is advisable to pre-mark and drill holes for self-tapping screws with a drill.

Important! It is necessary to precisely align and correctly install the very first sheet, the quality of all work will depend on it.

The first sheet is first fixed in the middle with one screw and the overhang from the cornice and the vertical position of the crate are carefully aligned. After that, it is fixed with a second screw.

The material is attached to the upper and lower boards of the crate by screwing self-tapping 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. They cut the profiled sheet with an electric saw, a hacksaw for metal or an electric jigsaw with a metal file. They do it on the ground.

Attention! It is impossible to cut a profiled sheet with a grinder. This will destroy the polymer coating. For cutting, use scissors for metal, and paint over the cuts with paint.

Horizontal joints are also sealed with tape. Self-tapping screws on the overlap 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.

Installation of the skate on the corrugated board

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 semi-circular edge
with a U-shaped rib and shelves of the same dimensions.

To install a ridge on a corrugated roof, the last row of sheets should be aligned in the upper part along the end and laid in the same horizontal plane. The installation order is as follows:

on the edge of the last row of sheets, a tape or a strip of ridge seal is laid,
bars are fixed parallel to the axis of the ridge,
ridge elements are screwed to the bars with screws into the upper corrugation after 20-30 cm, starting from the side where the wind most often blows,

In order to begin work on the installation of corrugated roofing, it is necessary prepare the following tools:

hacksaw or jigsaw;
roulette;
screwdriver
metal scissors;
construction stapler;
screwdriver or drill.

If you are installing a do-it-yourself corrugated roof, then you need to think about the appropriate choice of rafters and battens, since these roof elements are often influenced by the type of corrugated board from which the roof is made.

Video about the installation of corrugated roofing on the roof with your own hands.

Depending on the type, size and area of the roof need to calculate the number of sheets of corrugated board and additional accessories that will be needed when installing the roof. However, for the device complicated roof more elaborate accessories may be required than for a simple gable roof.

Before starting the installation of corrugated board sheets, it is necessary to waterproof and vapor barrier the roof. For waterproofing, a special film is used, which is laid on the rafters and fastened with a stapler. Next, the crate is laid.

Since moisture can form between the roof and the waterproofing layer, it is recommended to place the crate on wooden slats laid on the waterproofing for ventilation.

How to fix corrugated board on the roof

How to fix corrugated board on the roof? For fastening corrugated board self-tapping screws are used on a wooden crate. Self-tapping screws are made of galvanized steel, and the steel contains a special stabilizer that prevents aging of the material from the action of ultraviolet radiation. Each self-tapping screw has a special sealing gasket made of elastomer. Such a gasket protects the wooden fasteners from rotting and the edges of the fastening hole from corrosion.

When calculating the required number of screws proceed from the fact that on 1 square meter corrugated roofs require approximately 8 self-tapping screws.

Self-tapping screws are installed using a screwdriver. In this case, the screws are screwed into the lower wave of the sheet.

Fastening of corrugated board near the cornice is carried out with self-tapping screws located at a distance of 30-40 cm from each other. The following screws are installed through the wave, and the fastening pitch is 1 m.

Near the frontan, self-tapping screws are installed at a distance of 50 to 60 cm from each other. On the vertical overlap, the screws are located in increments of 30 to 50 cm.
