CLASSICA and ELEGANT are attached directly to the battens self-tapping screws through a bend hidden during installation; between themselves, the panels are attached to a self-latching fold. The presence of ribs increases the rigidity of the panel during installation and transportation and reduces the noise level from external influences during the operation of the roof.

PRAGMATIC is fastened to the crate with the help of "PRAGMATIC" clamps (Fig. 14), the panels are fastened to each other on a self-locking fold. Roof panels with l-shaped fold are attached to the crate using "STANDART" clamps (Fig. 15); are interconnected by a double standing seam using a manual or mechanized tool.

Seam panels are manufactured at the INSI Facade and Roofing Factory according to pre-declared lengths, which are determined as a result of careful measurements of the roof slopes (basic size: from the eaves to the ridge).

2. Accessories

3. Lathing for seam roofing

Seam roofing is installed on a sparse or continuous crate. To prevent sagging of steel sheets, it is very important to observe the required design step of the crate during installation. The following can be used as a crate: galvanized metal profile ПШ-28 manufactured by CJSC INSI, wooden beam 50x50, board 32x100, which are attached from the bottom up (from the eaves to the ridge). From correct device The durability of the roof depends to a large extent on the crates, because even a slight deflection of the sheets weakens the density of its folds.

For seam panels with a self-locking seam, it is recommended to use a metal crate. If used as a crate wooden planks or bars, you must follow the instructions of paragraph 7.3 of SP 17.133330.2011. ROOFING.

When using a metal crate and a discharged wooden crate, before installing it on the rafters, it is recommended to lay an anti-condensation film. In the case of using a solid wooden crate or other solid bases (flooring), it is recommended to lay a special structural vapor-diffusion film directly on the flooring. This film provides:

• permanent device ventilation duct to remove condensed moisture that forms on inside metal roofing;
• prevention of metal corrosion and wood decay;
• noise reduction from rain and hail.

In the places of installation of cornices, valleys, junctions with the protruding parts of the building, a second profile of the crate is installed, which gives additional rigidity to the panels. In the region of the valleys, the pitch of the lathing profiles is not more than 200 mm. In the area of ​​​​installation of snow retainers, it is necessary to install two hat profiles one after the other.

For Standart seam panels with roof slopes of 3-20°, it is recommended to use a wooden crate. Along the eaves, along the entire perimeter, it should be made in the form of a continuous boardwalk with a width of at least 700 mm. In the grooves and valleys, the crate should be made in the form of a continuous boardwalk up to 700 mm wide on each slope. It is also recommended to use a continuous crate with a complex roof configuration. In the area of ​​the transverse joint of the folded panels, a board with a width of at least 120 mm should be laid. A joint of panels is formed on it with the help of a recumbent fold.

The crate under the roof should be even, without protrusions and recesses; the ridge and ribs must be straight; the bottom board of the cornice overhang must be straight. Wooden crate is made of pine, spruce, fir and aspen. The moisture content of wood should not exceed 12%. To protect the wood of the roof sheathing from decay and extend its service life, the wood is impregnated with antiseptics, coated or painted. The service life of wood increases and if it is covered with drying oil in a dry state. Requirements for a wooden crate and its installation are listed in SP 17.133330.2011. Lay a special structural vapor-diffusion film along the crate.

In the construction of an insulated roof, to ensure ventilation under the roof space, it is necessary to use a counter-lattice, under which a hydro-windproof membrane is attached, and only then a crate.

4. Installation of a roof from STANDART panels

Options for joining panels along the length, devices for cornices, ridges, finishes chimneys, shaft ventilation for roofs made of Standart seam panels with various slopes is recommended to be adopted in accordance with SP 17.133330.2011. With a minimum slope of 3°-10°, it is necessary to seal the seam roof with the sealing tape Abris S-LB. Maximum length the slope, when fastening the seam roof with fixed clamps, should be no more than 6 meters. For longer lengths, it is necessary to use "sliding" clamps. The locations of "sliding" and fixed clamps along the length of the panel should be taken in accordance with SP 17.133330. 2011, appendix C.

If a device is provided from the roof organized drainage, the gutter holders must be secured before the roof deck is installed. They are fastened with a step of no more than 750 mm to the rafters or the bottom lath of the crate (see installation drainage system).

Then a cornice is attached along the lower edge of the slope. Fastening is carried out with self-drilling galvanized flat head screws (Fig. 16)

5.2 Mounting the seam roof valley

At the next stage, the installation of the elements of the valleys is carried out. During installation, only the lower valley is used. Fastening is carried out with self-drilling galvanized screws with a flat head, along the edge of the valley, closer to the bends. The junction of the valleys is carried out with an overlap of at least 200 mm, the upper elements must be wound onto the lower elements. The edge of the seam roof valley is brought out to the eaves (Fig. 17). Figure 18 shows an option for attaching panels to a valley. At a distance of 100 mm from the inner bend of the valley, a seam roofing sealant is applied. Folded sheets are laid on it and attracted to the valley with roofing screws painted in the color of the roof.

Before starting the installation of folded panels with your own hands, it is necessary to perform a control measurement of the slopes with the establishment of flatness and perpendicularity with respect to the lines of the ridge and cornices. The diagonals of the rectangular slopes should be equal. Seam roofing can be laid both from left to right and from right to left, strictly observing the direction: with the lower lock towards the subsequent installation. Therefore, when lifting the panels, it is necessary to turn them around, taking into account the direction of installation. For installation of seam panels, self-tapping screws 4.8x22 with a press washer are used, and for component elements and in places where panels overlap along the length - 4.8x20 (for metal crate seam roof) or 4.8x35 mm (for wooden sheathing) with a sealing gasket. Sheets are fastened to each line of the crate. Each subsequent panel is aligned with the slope, superimposed on the previous one, snapped into place and then attached to the crate. Fasten the folded edge of the panel along the eaves and ridge with 4.8x20 (4.8x35 for wooden crates) painted screws with a sealing gasket, two screws per fastening. (Fig. 19).

When arranging longitudinal joints, the sheets are mounted from the bottom up. With a slope length of more than 6 m, it is recommended to make it composite due to the inconvenience of transporting and installing sheets. Seam roof sheets are laid with an overlap along the length of 200 mm. Adjacent joints must be at least 400 mm apart. Thus, the plane of the roof with a long slope usually consists of two standard sizes of panels "a" and "b". In this case, the length of panels 1 and 2 differs by the spacing of the joints (Fig. 20).

When installing a composite ramp, operations are performed in the following sequence (Fig. 21):

1) trim the bottom of the "lock" with outside on panel 1 (Fig. 22); 2) fasten panel 1 with self-tapping screws to the crate; 3) put panel 2 on panel 1 with an overlap of at least 200 mm and fix it to the crate with self-tapping screws; 4) cut the lower part of the "lock" of panel 3 (similar to item 1); 5) make lock connection of panel 3 with panels 1 and 2; 6) fasten the panel with 3 screws to the crate; 7) panel 4 is superimposed on panel 3 with an overlap of 200 mm and is connected in a "lock" with panels 2 and 3; 8) fasten the panel with 4 self-tapping screws to the crate. Then repeat steps 1 to 8.

5.4 Gable

The pediment-45 is fastened in such a way as to cover the upper fold. The pediment is fastened to the lower bend (Fig. 23). If a sheet was cut, it is necessary to bend the edge of this sheet up by 20-25 mm (Fig. 23). The pediment is fastened roofing screws with sealing gasket.

5.5 Skate

The ridge is installed on the upper edge of the slopes on the finished roofing. Top part folded pictures is folded up by 25 mm. The skate can be shaped (semicircular) or flat. During installation cold roof with a slope of 25 ° or more, the ridge is fastened with roofing screws into the upper edge of the seam lock (Fig. 24).

5.6 Wall profile

At the junction of the roof to the wall, pipes and dormer windows a wall profile is installed. The profile is superimposed on the folded panels (the panels are bent upwards by 25 mm along the edge of the junction with the wall) and attached to the wall (Fig. 25).

Brick protruding from the roof rectangular pipes framed by a wall profile according to fig. 27-32. The number of profiles is equal to the perimeter of the opening in the plane of the roof plus 2 meters.

step 1 - Installation of the lower pipe apron (fig. 26)

First you need to prepare the junction of the lower apron to the side surfaces of the pipe. To do this, using the elements of the apron as a template, cut lines are marked on the pipe. Then, with the help of a corner-cutting machine ("grinder"), a strobe is made in the brick walls of the pipe. Having cleaned the strobe and the surface of the lathing from brick dust, the installation of the elements of the lower apron begins, after cutting each element and bending it along the slope of the roof. When installing the apron, the bent upper edge is inserted into the strobe, the vertical wall is pressed tightly against the surface of the pipe, and in this position the element is fixed with roofing screws with a sealing gasket to the crate. The first element is mounted to the bottom face of the pipe, then two side ones and at the end - the element to the top face. The overlap of the upper elements on the lower ones must be at least 150 mm. After fixing all the elements to the crate, the edge of the apron inserted into the strobe is coated with silicone sealant. Attention! For better adhesion, the strobe must be washed with water.

step 2 - Installation of the bottom sheet from the pipe to the cornice (Fig. 26)

At this stage, a flat (galvanized or painted) sheet is installed. The length of the sheet must correspond to the distance from the lower edge of the pipe to the eaves or the nearest valley, the width must be not less than the width of the lower element of the apron (including side bends). Bring one edge of the sheet under the lower element of the apron, and bring the other from above, onto the cornice or valley. After fixing the flat sheet to the crate from its sides, make bends with a hand tool.

step 3 - Laying the seam panels (fig. 27)

Lay the seam panels from the bottom and from the sides of the pipe, beforehand bending upwards by 25 mm at the junction points.

step 4 - Installing the wall profile along the bottom of the pipe (Fig. 28)

Install the wall profile to the lower edge of the pipe, preliminarily adjusting it to the width of the pipe, according to the figure. Cut the protruding vertical parts from the bottom and bend to the side edges of the pipe. The profile is attached to the pipe using dowels with mandatory sealant treatment.

step 5 - Installing the seam roof on the side faces of the pipe (Fig. 29)

step 6 - Installation on the top face of the pipe (fig. 301)

Install the wall special profile on the upper edge of the pipe. Cut the protruding vertical parts from the bottom and bend onto the side edges of the pipe, securing with dowels.

step 7 - Installing the seam panel on top of the pipe (fig. 31)

Install the top seam panel over the wall profiles and side seam panels. Leave a gap of at least 100 mm between the bottom edge of the panel and the pipe. Treat the lower edge of the standing seam (50 mm) with a seam roof sealant.

If it is planned to sheathe the pipe with a profiled sheet, then after framing the pipe, a hat profile frame is mounted, a profiled sheet is attached to it, the corners are made out with an outer corner 50x50 (Fig. 33)

The chimney is attached to the pipe with dowel-nails before the installation of the profiled sheet.

The number of drainpipes is determined from the standard - no more than 52 sq.m for a pipe with a diameter of 100 mm of the roof area per one drainpipe. Usually the number of downspouts is chosen for aesthetic reasons. Drainage systems should be avoided north side buildings to prevent freezing in winter.

In case of a risk of freezing of the drainage system, heating systems for gutters and pipes can be used.

Gutter holders are mounted at a distance of 0.75 m from each other, pipe holders - no further than 3 m from each other (for example, 3 holders are needed for a 5 m long pipe, two are enough for a 3 m long pipe).

With a catchment area of ​​​​less than 30 sq.m., gutters can be installed with a zero slope per downpipe, with larger area catchment gutter slope can be up to 5%.

step 1 - Installing the gutter holders

Mounting spillway system starts with the installation of the gutter holders. Divide the total length of the gutter into equal segments, as noted earlier (but not more than 900 mm).

step 2 - Marking for gutter holders

According to the result obtained, mark on the lower crate the installation locations of the gutter holders.

step 3 - Bending the gutter holders

Number the holders from the top mark to the drain funnel. By defining for yourself desired slope(up to 5%), mark the place of the bend on each holder. In this case, the place of the bend of the holder should be lower than the design position by 2.0 - 2.5 cm relative to the roof slope line (Fig. 36).

step 4 - Attaching the gutter holders

Aligning the bend with the edge of the battens, attach the gutter holders with self-drilling galvanized screws 4.8x22 with a flat head, 3 pcs. on the mount. When using 50x50 bars as a crate, a double bar must be installed to securely fasten the holders.

Step 5 - Creating a slope

Fit two wall profiles to the dimensions of the side faces of the pipe. Installation of profiles - by analogy with the installation of the lower profile. To the seam panels, fasten the wall profile to the sealant using roofing screws with a sealing gasket.

step 6 - Mounting the nozzle

In the gutter, at a distance of 150 mm from the bottom edge, cut a hole with a diameter of 100 mm for the branch pipe. Insert the branch pipe in the place of the hole (Fig. 38) Insert the front edge of the branch pipe under the outer bend of the gutter. Bend the nozzle flange onto the rear edge of the gutter and fasten it with two 4.2x16 self-tapping screws (Fig. 38).

Step 7 - Installing the Gutter Ends

Install gutter plugs at the ends (Fig. 39).

step 8 - Installing the gutter

Insert the chute into the holders by inserting the rear edge of the chute into the ledge of the holder (Fig. 39).

step 9 - Connecting the gutters

Install the connecting element of the gutter at the junction of the gutters (Fig. 40 and 41).

step 10 - Mounting the angled elbow

Use the corner elbow to create a transition to the building wall. Length connecting pipe determined locally (Fig. 42).

step 11 - Mounting the pipe

The pipe is fixed to the wall using pipe holders. The pipe is measured, if necessary, extended at the place of installation of the pipe holder, fixed with a lock (Fig. 43).

Step 12 - Mounting the Drain Elbow

The drain elbow completes the drainpipe, serves to drain water from the foundation of the building; should be located at a distance of 300 mm from the blind area of ​​the building (Fig. 44).

7. Snow holder and seam roof fencing

For safe movement on the roof at the level of the eaves, starting from the second line of the crate, roof railings are installed.

The fence is made depending on the slope of the roof and its type. Seam roof fencing is fastened to the sheathing profile through a seam panel and a sealing rubber gasket in the place of wave deflection with self-drilling galvanized bolts 5.5x25 mm for a metal crate and 5.5x60 mm for a wooden crate. It is forbidden to fasten a roofing fence to one seam picture. Between themselves, the sections of the fence are attached to bolted connections(Fig. 45).

To prevent the descent of large masses of snow, snow retainers are installed. The design of the snow retainer consists of brackets and pipes. The brackets are installed in the deflection of the wave and fastened through the metal and rubber sealing gasket to the roof deck. In the places of installation for fastening the bracket, an additional crate profile is pre-mounted at a distance of 120 mm. Snow guards are installed above the roof railing. In the absence of a roof fence, snow retainers are installed no lower than the third row of the crate. With a slope length of more than 10 meters, it is recommended to install two rows of snow retainers. In areas with large quantity snow precipitation provides for the installation of a thrust bracket. The snow retainer rod is attached at one end to the bracket and the other to the purlin profile through a sealing gasket and a metal tile sheet. Recommendations for the selection of the number of brackets, brands fastener depending on the construction of the folded roof and the snowy construction area, can be obtained from the program by setting all the necessary parameters. It is forbidden to fasten the snow retention bracket to one sheet.

8. Accessories

As accessories, weathercocks, decorative spiers, chimneys are installed on the roof. Installation of all accessories is carried out in accordance with the norms of SNiP.

For the device of exits from the roof of antennas, masts and ventilation pipes round section diameter up to 330 mm (with temperature outer surface up to 130)° used roof seals master flash.

9. Processing of wooden structures

Wooden structures used in the installation of seam roofs need antiseptic and flame retardant (fire) treatment. Processing can be carried out both before the assembly of structures (processing of individual boards and bars), and after (processing of rafters and battens). Processing is carried out various methods(immersion in a container with a solution, brush application, spray application).

10. Tools for the installation of seam roofing

1. Screwdriver with hexagon socket 8 mm.
2. Electric nibbler or nibbler.
3. Manual roofing scissors.
4. Mallets (wooden, rubber).
5. Hacksaw, jigsaw, hammer (used in the construction of rafters and battens).
6. Angle grinder ("Bulgarian"), puncher, drill, gun for pressing out sealant (used when installing a wall profile).
7. Level, level, plumb, measuring tools and fixtures.

11. Attention

Cutting seam panels and components with cutting and angle grinders ("grinders") is allowed only if the unprocessed areas are protected from flying sawdust and subsequent anti-corrosion painting of the cut points.

The use of polyurethane foam as ridge or valley seals is strictly prohibited!

All products manufactured by INSI Façade and Roofing Plant are designed for use on pitched roofs according to of this manual for installation. The INSI plant is not responsible for damages or losses that may occur when INSI products are used to perform functions that are unusual for them.

Seam roofing consists of galvanized and rolled steel, or non-ferrous metals and steel with a special polymer coating. She got her name because of the connection of her sheets by the folded method, i.e. fastening among themselves is carried out without nails, self-tapping screws and other devices. The result is a perfect and tight roofing. Freight transport is used to transport and transport sheets.

When unloading, all sheets must be transferred one at a time and in a strictly vertical position. To raise them to the roof, they use a ladder, stepladder, or boards that are placed between the ground and the roof.

The minimum allowable slope of slopes for roof covering is 7 °, but 14 ° is considered optimal. A strictly defined step of the crate is also installed, it is equal to 40 centimeters, but no more. Metal cutting is carried out on the ground using metal shears. Seam roofing can be produced on a continuous and sparse crate.

For installation you will need: a hammer, a mallet, metal shears, pliers and roofing mandrels.

Consider step by step installation and installation of seam roofing.

Installation and installation of seam roofing begins with cornice strips. They are fastened with special roofing screws with a certain pitch (40 cm). After that, you need to spread the soundproofing tape under each sheet. In this case, the edge of the tape from below and above should be at the second level.

Sheet fastening

It is possible to start installation and installation from any edge. Although the manufacturers of some sheets provided for their fastening only from right to left. The first sheet must be laid with a 10 cm extension above the cornices. If some sheets have a bottom bend, then they will rest against the eaves. The edges of the sheets can be bent even after installation. The sheet must be installed as accurately and evenly as possible vertically and horizontally. Next, proceed to attach it. There must be a right angle between the sheet and the cornice. You can easily determine it with a large square.

A correctly laid first sheet is the key to successful installation of subsequent sheets.

There are two main types of fastening sheets: using special clamps and self-tapping screws. When buying sheets, some of them, depending on the manufacturer, have holes into which screws can be screwed. They overlap with the following sheets, the edges of which are bent. But, if there are no holes, you can use a seam roof clamp. Such key connections are different.

With the help of clamps, the sheet will be fastened as follows: initially, the clamp clamps are fastened with nails to rafter leg on the gable, then the opposite ends of the clamps must be bent so that they securely and firmly hold the sheet. After that, clamps are also used for fastening on the opposite side of the sheet, only of a small size. The step between all fasteners is 60 cm.

Installing subsequent sheets

Installation of the skate

To install the ridge, special ridge pads are used. Their edges are already bent. With their edges, they are attached to the sheets, after which the already familiar lock connection is carried out on both sides. In this case, the skate can be made either non-ventilated. Our advice is to opt for ventilation, as in this case you will avoid additional work on the subsequent installation of roof aerators.

There are a lot of options for seam roofing and its installation. Which one you will use - you will find out after the purchase. Today, there are many coatings with automatic locks on sale. This greatly simplifies the entire assembly and installation process. If standing seam joints are not suitable for you, you can always make them recumbent by simply bending them to the surface.

correct and quality installation will give your roof a beautiful appearance and help you avoid various negative elements in the future.

The work is carried out in several stages.

The first stage: the manufacture of folded "pictures" for ordinary covering of roof slopes, as well as cornice overhangs, wall gutters.

Due to the variety of individual components, for the manufacture of additional elements and rental of paintings, the necessary blanks are made right on the construction site various forms and dimensions, based on the drawings of the future roof. steel sheets, cut into strips, the specialists of our company manufacture (roll) on our own German equipment of the SCHLEBACH company, which forms a finished picture with a double standing seam.

Second phase ( seam roof installation): paintings are lifted to the roof and their sides are connected to each other with a standing seam. Then the paintings are attached to the crate with narrow steel strips - clamps, which are led into standing folds at one end when they are bent, and the other is attached to the crate beam.

Thus, a high-quality roofing is obtained, without any technological holes. Holes at the flue and gas pipes, including ventilation ones, are covered with galvanized steel aprons.

Galvanized roofing cannot be painted with conventional enamels, nitro and oil paints . Roofing galvanized steel is coated in the factory with protective polymer coatings. More often this is done with rolled roofing materials. The roll technology is so called because the roofing "paintings" are made directly on construction sites from metal delivered in rolls and can be of length equal to the length roof slope. This is what allows you to avoid transverse (lying) folds. The connection of roofing paintings is carried out, as a rule, in a double standing seam. To ensure complete impermeability of the joints, the fold can be sealed with special sealants.

Advantages of roll technology (double standing fold):

· the possibility of using not only ordinary galvanized steel, but also polymer-coated steel, which is more corrosion and wear resistant than traditional steel, and therefore more durable;

Ensuring a high degree of tightness of the coating (due to rolling into a standing double fold of longitudinal seams of adjacent roofing sheets and, as a rule, the complete absence of horizontal lying folds);

high manufacturability and reduced labor intensity of work;

practical noiselessness, which is extremely important when working in densely populated areas;

· possibility of application for roofs with any slope, any even complex configuration and any size;

· the mobility of the equipment, which allows you to perform all the work not only directly on the construction site, but also directly at the workplace of the roofer.

Installation of a double standing seam (folded roof)

Installation of a seam roof using the technology of a double standing seam is carried out on a solid base using special aluminum clamps.

click-fold

There is another modern variety seam roofing: from special steel panels with self-locking seams - Click-Falz.

Roofing system Click seam - competent and actual solution for roofing, since the installation technology, compared to other roofing materials, is much faster and easier.

Pictures are made on modern European equipment in various polymer coatings and various thicknesses from European and domestic steel. The length of the picture is made to order in the range of 1.2 - 9 meters. Unlike the classic double standing seam, the click seam is not made in materials such as copper, zinc, titanium, and aluminum. All additional elements are produced in a standard version and are mounted on self-tapping screws, and, unlike a double standing fold, it is impossible to click a fold on the site of an object under construction.

One of the features of the roofing, made in click-seam panels, is the possible presence of waviness in the paintings, it is caused by the specificity this material. To reduce the effect of waviness will allow metal with a matte polymer coating.

Such folds are connected to each other without using a special tool.

Click-fold installation

Features of installation of a roof from folded pictures:

A properly installed seam roof is not a guarantee of leakage if roofing cake, mounted with deviations from the norms and SNiPs.

When installing a roofing pie, it is important to observe the technically competent execution of nodes, which will ensure proper ventilation and prevent heat loss. If we consider the entire roofing pie, then you need to approach each node carefully and pay attention to all the subtleties and nuances.

We recommend using first grade lumber and GOST, so that the board is calibrated, thereby eliminating the risk of steps and waves in the rebate coating. With an insulated roof, it is necessary to use not only a good multilayer waterproofing membrane but also quality vapor barrier film mounted under the heater. When choosing a heater, our company uses and recommends mineral wool based on basalt. Also important point, is the processing wooden structures roofs with a fire-bioprotective composition, which will prevent premature exit roof structures out of service. All fasteners must be galvanized from trusted manufacturers. As a rule, when performing work on the installation of a rafter system and a roofing pie, galvanized screw or ruffed nails are used, and movable and fixed stainless steel clamps are used for hidden fastening of folded paintings.

On the territory of Russia, metal roofs are traditionally in demand, this is due to heavy climatic conditions that do not spoil the inhabitants of the country with warm and dry weather. Despite the abundance of materials, roofing steel is considered the most reliable way to protect the house from the penetration of precipitation. Seam roofing is a technology that does not lose its relevance, making the joints of metal sheets on the roof airtight.

The seam roof got its name due to the connection system between the sheets of metal, called the seam. He is special kind seam, which creates a self-locking edge. Most often there are roofs with vertically located folds, but there are also horizontal options. Roofers distinguish the following types of seams between sheets:

• Standing single fold. It is a single comb of triangular section, located along the edge of a sheet of metal. The comb of one sheet is put on the comb of the adjacent one and fixed on the crate of the slope with the help of clamps.
• Standing double fold. This type of seam, with which the seam roof is connected, is a double bend protruding above the level of the sheet. The technology of connecting roofing elements using a double seam is considered the most hermetic.
• Lying single fold. In order to install a seam roof with a double seam, a single bend is performed along the entire edge of the metal sheet. Most often, this technology is used to perform horizontal seams.
• Lying double fold. The device of a double lying fold consists in the formation of a fold along the edge of the sheet, consisting of 2 turns. Compared to a single one, this technology has better protection against water penetration and leaks.
• Clickfalz. On the one hand, a self-latching seam roof has a decorative bend that imitates a seam, and on the other hand, a spring-loaded click seam. Such a device allows you to install a seam roof faster by snapping a sheet of metal onto the previous one.

Note! The construction and repair of a seam roof is a labor-intensive, painstaking process, which only an experienced roofer can perform with high quality. Self-locking technology has become great solution for those who appreciate the high operational, decorative qualities roofs of this type, but not ready to fork out for employees.

Types of metal

The operational qualities that a seam roof exhibits depend on the material of the sheets. Manufacturers currently offer the following options:

A sheet of metal, the edges of which are bent to make a seam connection, are called paintings. Produce roll materials, prepared for installation, which only need to be cut and fixed to the roof slope.

Note! Installation and repair of seam roofing made of copper and zinc-titanium is carried out with great care. In order not to damage expensive material, it should not be stepped on, scratched, or thrown. The service life of the roof depends on the accuracy of handling metal.

Advantages

In favor of the seam technology, the trust of roofers and the debt of successful experience in the harsh Russian winters speak. The advantages of this type of roof include:

• High degree of protection against moisture penetration. Such a device of the connecting seam does not allow the penetration of water under the roofing material. Flat roof technology implies that there are no through holes in it.
• Ease. Sheets of metal, the thickness of which reaches 0.5-0.6 mm, are lightweight and do not overload the truss frame and the foundation of the house.
• Smoothness. Smooth surface slopes and longitudinal seams do not impede the sliding of snow masses and rainwater from the roof, preventing collapses and deformation.
• Long service life. Subject to high-quality installation, compliance with the operating rules prescribed by the instruction, the operation time of a flange-type roof exceeds 50-60 years.
• Fire safety. Metal belongs to the class of non-combustible materials, it does not burn, does not support combustion and does not melt.

Important! When installing and repairing a seam roof, take into account that it has high heat-conducting and resonant properties. To minimize these negative qualities of the design, it is necessary to use high-quality heat and sound insulation. In addition, metal accumulates static electricity, so the fire safety instruction prescribes to equip roofs with such a coating with a lightning rod.

Mounting

The instruction is not able to describe in detail how the installation and repair of the seam roof is performed. Its device is most often entrusted to a roofer with sufficient experience and knowledge. Schematically, the process of laying roofing in this way looks like this:

Important! Roll mounting technology significantly reduces the time spent on roofing. It allows you to cut strips of length corresponding to the length of the slope from the roll. Absence horizontal connections between sheets reduces the likelihood of leaks, increases the life of the roofing.

Video instruction

Seam roof - the most reliable way roof arrangement. The seam method gives the most hermetic connection metal sheets. Besides, metal roof distinguished by beauty and durability.

A fold is a seam with which sheets of metal are connected to each other. Seam joints are completely sealed. Seam roof, thanks to this technology, is the most reliable and durable type of coating for the house. This fact is recognized by both construction specialists and ordinary consumers.

Benefits of seam roofing

• The main advantage of a folded roof is its tightness, which is achieved by the installation of a folded seam. The peculiarity of this seam is that the seam roof installation technology does not allow the presence of holes on the sheet of the roofing material, and, accordingly, completely eliminates the ingress of moisture into the structure;
• a small mass of roofing sheets with a thickness of 0.5-0.6 mm significantly reduces the load on the foundation and truss system buildings;
• a smooth plane contributes to the rapid descent of rain and snow, protecting the roof from damage;
• fire safety. The seam roof is metal, so it cannot burn and melt;
• durability. If the seam roof is installed with high quality, its service life reaches 60 years or more.

The disadvantages of seam roofing

• Difficulty of installation. Do-it-yourself seam roofing can be equipped only if you have the skill of working with metal;
• The need to build a lightning rod due to the ability of the roof to accumulate electrical voltage;
• High resonant properties. The sound of raindrops is quite noticeable, and therefore measures are required to equip additional sound insulation.

The disadvantages also include the high cost of roofing with a special coating to give a more aesthetic appearance to the structure, since the most simple version(galvanized steel) does not look very presentable.

Seam roof device

For the construction of a folded roof, sheets of metal are required, prepared for installation in a special way. They are called "pictures", and are a canvas with curved edges that serve as the basis for a fold (seam). To fix the metal on the roof, a seam roof clamp is used. These seam roof elements can be purchased at the store or made by yourself with a special device.

When arranging a seam roof, installation can be carried out in different options. The folds are located not only vertically (the most common type), but also horizontally. The seams themselves also have several varieties.

Standing single fold is the simplest. The folded edge (fold) of one picture (sheet) is put on the bend of the adjacent picture and fastened to the crate with a clamp.

A standing double fold is more airtight, since in this case a double bend is made.

The recumbent single fold is an example of a horizontal arrangement and is used quite rarely due to poor reliability. In order to avoid the need to make horizontal folds, not sheet, but rolled metal is currently used.

The recumbent double fold assumes the presence of a bend of two turns. This seam roofing technology provides greater tightness than a single one.

Seam roofing is mounted manually or using an electromechanical seaming machine.

How to make a seam connection with your own hands, see the video:

Clickfalz. To speed up the installation of a seam roof, use the so-called self-latching roof - clickfalz. Self-latching seam roofing does not require the use of any special tools. It is arranged in such a way that the edges of the paintings interlock with each other into a lock with a slight pressure.

Since high-quality installation and repair of a seam roof manually can only be carried out by a specialist roofer, a self-latching seam roof is a real find for those who have opted for this type of roof.

Materials for metal seam roofing

One of the most popular seam roofing metals is galvanized or polymer-coated steel. durability, corrosion resistance, acceptable price- these are its characteristics.

Galvanized seam roofing becomes stained over time and therefore requires periodic tinting.

An alternative is steel with a polymer coating. It should be taken into account that different coatings perform different functions. Some prevent the negative effects of natural phenomena (for example, pural), others increase strength (plastisol). Polymer coatings have a rich color scheme which is important from an aesthetic point of view.

The seam roof made of copper looks very beautiful. Its main advantage is that no microorganisms, including moss, can live on it. Copper under the action environment covered with a patina - a layer of green oxides, which makes the roof even more beautiful. It is because of the oxide layer that it is not recommended to combine this metal with others. copper, how about soft material, requires especially careful handling, especially since its cost is quite high.

Installation of a copper seam roof is easier than any other. The plasticity of this material allows you to create a coating on the roof of almost any configuration.

Zinc seam roofing gradually becomes silver-gray, which gives it splendor. It is coated with zinc carbonate - a special protective layer. However, due to the short service life (50 years), zinc roofing is not currently used in Europe.

Aluminum seam roofing is corrosion resistant, durable (service life of more than 100 years), has a beautiful shine and low weight. The disadvantage of aluminum roofing is the dependence on temperature changes. A feature of the installation of such a roof is the use of floating clamps and galvanized self-tapping screws.

Zinc-titanium is a strong alloy that makes the roof durable and ductile at the same time. It is very attractive from a design point of view - the noble patina gives splendor.

Titanium-zinc-copper alloy has a high degree plasticity, which greatly facilitates the process of giving the metal a pattern (profiling).

Aluzinc is a unique alloy of aluminum and zinc, which is used to coat steel paintings in order to protect them from corrosion.

In conditions of high humidity and temperature, as well as in areas with difficult ecology, it is recommended to install seam paintings with a special pural coating. Pural is a polymer that perfectly protects the roof from exposure to sea air, acid rain and hot sun.

It should be noted that such expensive materials as copper and zinc-titanium require extra care when installing seam roofing. Careful handling at the installation stage will significantly extend the life of the roof.

Types of folded roof

There are two types of seam roofing - cast and rolled.

A cast (sheet) seam roof without transverse seams can be assembled by hand without the use of special roofing tools. Solid and durable, such a seam roof has long been recognized in Russia.

Roll technology for the production of folded roofs got its name because roofing paintings are made of metal rolled into a roll. On a seam-rolling machine, a picture of the desired length with a double seam is formed directly on the construction site.

The most popular both in Russia and abroad are the products of the Finnish company for the production of folded roofing with self-latching folds Ruukki.

Another famous brand- folded roof grand line. The Grand Line Company is one of the largest Russian manufacturers of materials for cottage and low-rise construction. The company's factories produce two types of seam roofing - Klickfalz and double standing. A wide palette of colors and various types of polymer coatings make it possible to create a masterpiece roof.

Mounting technologies

Roof installation technology depends on whether the attic is warm or cold in the project. We will consider the option of a mansard insulated roof with a seam roof. The most reliable is considered to be a roofing pie with a spaced ventilation gap and an antioxidant film.

The truss system from a bar serves as the basis of an underroof. To support the insulation, a sparse crate is built, and above the insulation layer there should be air gap and a wind barrier (super diffuse membrane). Further - continuous crate, hydrobarrier (antioxidant film). The final stage is the seam coating.

Important! Before styling insulating materials you should carefully study the instructions. Each side of these materials performs a specific function, and improper installation can lead to the opposite result.

Prior to the construction of the crate for the seam roof, the cornice floor should be mounted and sheathed gable overhangs. This design must be attached to the rafters, for which bolts and nails are used. The crate must withstand the loads created by the roofing material and be as even as possible.

Lathing for seam roofing can be made of board, wooden beam or steel profile. The step of the lathing under the seam roof is 20-25 cm. With such a lathing device, the metal is not subjected to deformation, the degree of resonance is significantly reduced. For a copper seam roof, which has the greatest weight, the crate is made continuous.

When installing a seam roof, the angle of the roof slope should be taken into account. The type of fold that will provide highest quality coatings. The minimum slope for a seam roof is 3 degrees. This angle of inclination requires the installation of a double vertical seam and an additional dewatering layer. The greater the slope of the slope, the less likely the stagnation of water on the roof.

To minimize snow avalanches, roof railings. In addition, the installation of fences for seam roofing is necessary for safe work builders who install or repair the roof. There are special instructions, the execution of which will help to avoid trouble during the construction and operation of the roof.

Roofing tool

For the manufacture and installation of seam roofing, there is special equipment.

Previously, you can make paintings using a folding machine.

To obtain a seam connection directly on the roof, a tool for seam roofing of two types is used.

For manual (mechanical) seaming of the fold, equipment is used in the form of a set consisting of pliers with two frames closing the folds.

Sealer is a type of electrical equipment. The use of such a machine significantly increases the speed of roof installation and eliminates physical activity roofer.

The appearance of the seam roof is very aesthetic and beautiful. Subject to taking into account all the recommendations, it is possible to build a structure that will delight the eye and create the most comfortable living conditions for many years.
