Seam roof installation - technology. Instructions for installing a seam roof with your own hands and preparing the necessary roofing tools Seam roof installation
It is very convenient to use metal as a roofing coating - it is durable, non-flammable, highly resistant to atmospheric phenomena, and besides, it provides the maximum possible strength of the roof structure with its relative lightness in all its diversity. Among the materials used for roof waterproofing, there are galvanized steel and copper, aluminum and steel profile, both in the form of , and in combination with composites, imitating . In this article, we will look at how to install a seam roof made of galvanized steel.

What is a seam roof made of?
Seam roofing got its name from a special method of attaching metal sheets of roofing material to each other. A special system of joints guarantees absolute tightness without the use of rubber seals, adhesive seams, and most importantly - through holes, which will cause leaks. In addition, the stiffening ribs obtained during the folding process give the roof additional strength and expressiveness. It is used on roofs with a slope of at least 30%.
Galvanized roofing steel , one of the most popular roofing coatings, differs from ordinary cold-rolled steel in the presence of a thin anti-corrosion coating, a zinc layer about 0.2 mm thick, which significantly increases the life of the material.
The main parameters of galvanized roofing steel:
- length up to 2.5 m;
- width - 0.8 -1.25 m;
- thickness - 0.5 - 1 mm.
The best option for obtaining high-quality galvanized steel is the use of steel sheet metal grade ST 08PS, where the abbreviation PS means semi-quiet steel (a metallurgical term meaning steel containing a certain percentage of iron oxide in its composition, which causes the release of gases, without "boiling", from steel during its hardening after pouring).
A hot-rolled billet used to produce a galvanized sheet is pickled with acid to remove scale from its surface and brought to the required thickness by cold rolling. To give the workpiece the necessary strength characteristics, it is fired on a special bed.
Then the metal is immersed in baths with a zinc-based melt, the composition of which determines the main property of the future galvanized sheet - high resistance to the damaging effects of corrosion.
For galvanizing, zinc grades TsO and Ts1 (sometimes Ts2) are used. Their use is dictated by the requirements of GOST.
What to look for when choosing a material for seam roofing?
The right choice of material is the main requirement, following which you can perform a high-quality installation of a seam roof made of galvanized steel. The presence of defects in the material can lead to a significant reduction in the life of the roofing. Therefore, when buying material, you should pay attention to:
- presence / absence of cracks on the surface of the rolled product;
- zinc coating must be clean and uniform;
- a sheet of metal should be without "torn" edges;
- a continuous zinc coating should not be disturbed by sagging, dark dots, various grains, uneven crystallization of zinc, various kinds of roughness and scratches and other defects of this kind.
The minimum thickness of the material for the installation of a roofing sheet should be 0.5 mm, for the installation of overhangs and slopes - at least 0.7 mm.
Pictures and folds
Seam roofing with a continuous coating covers the entire length of the roof slope, where individual sheets are connected with a seam lock into “pictures”, and the latter, in turn, are connected to each other. What do such expressions as "picture" and "fold" mean?
Painting - a sheet of roofing steel, the edges of which are prepared for seam connection.
Falz - type of seam formed when connecting sheets of metal roofing material. The folds are divided by shape into standing and recumbent, and by density - into single and double. Recumbent seams are used for horizontal connection of roof sheets located along the water flow from the roof. Standing - for fastening vertical (side) strips of roofing material, fastening pictures on skates and ribs.
With slopes less than 60% of the roof, the recumbent folds in sheet steel roofs are made double and sealed with sealant. The size of the bending of paintings for the installation of recumbent folds is taken 15 mm, standing folds - 20 mm for one and 35 mm for another, adjacent picture.
In valleys, the folds of one slope should be at the same levels as the folds of the second slope
The folds are performed (rolled) manually with a special tool or more modern way- electromechanical seaming devices. Self-locking folds hermetically connect roof sheets without the use of tools. But the most reliable is considered a double standing fold.
Modern equipment for rolling folds allows you to make pictures of any shape: conical, radius and others, so the installation of a folded roof can be performed on roofs of various configurations. In this case, the seam seam can have a thickness of 5 mm and a height of 30-70 mm, depending on the slope of the roof.
Seam roof installation. Step by step instructions
Installation of a folded roof made of galvanized steel begins with the creation of a strong and even frame. It is made in the form of a crate of wooden beams with dimensions of 50x50 mm with a step of no more than 200 mm and boards 120-140 wide and 50 mm thick, laid every four bars with a step of 1390 mm (in places where the recumbent folds of joined paintings are laid). At the same time, the grooves, valleys and cornice overhangs are covered with a continuous boardwalk.
At the same time, pictures are being prepared. Folds are bent along the edges of the roofing sheets. Roofing sheets can be pre-connected to each other along the short side with a lying seam. The folds are bent towards the slope of the roof. In this case, the picture will consist of several roofing sheets. Steel sheets are cut with scissors or a guillotine, but in no case with a grinder.
If low roofs are covered, then the blank of the picture can be made for the entire length of the slope.
The next stage, which continues the installation of the seam roof, is the installation of cornice overhangs. Then install wall gutters and cover the grooves. And only after this, the pictures of the ordinary coating are raised to the roof and laid on the crate, securely joining each other, first on the short sides with a recumbent fold, and then on the long sides with a standing fold.
The installation of a folded roof does not provide for fastening through a sheet of metal, so the roof is obtained without technological holes. Pictures are fastened to the crate with clamps - strips of roofing steel 50 mm wide and 150 mm long, one end of which is led into the fold, and the other is nailed to the bars of the crate. This is convenient if the width of the sheets from which the picture is assembled is 50-60 cm. The most common size of a galvanized sheet is 1 x 2 m, so it is cut lengthwise into two equal strips, 0.5 x 2 m in size. Clamp fastening step - 0.5 - 0.7 m.
On the overhangs, the roof elements are attached to T-shaped crutches, nailed to the boardwalk in increments of no more than 70 cm and with a 12 cm overhang of the boardwalk. .
Drainpipes are hung on the walls of buildings using mobile scaffolding or mechanical towers after the roofing work is completed. They are attached to the walls with pins and clamps so that the gap between the wall and the pipe is at least 120 mm.

Installation of seam roofing from rolled material
When repairing or re-roofing for industrial, administrative or multi-storey residential buildings, you should pay attention to seam roofs made of rolled materials: galvanized steel (including color-coated) or non-ferrous metals (copper, titanium-zinc, aluminum).
From rolls of galvanized (in this example) steel mechanized way blanks, paintings, up to 625 mm wide and not less than the length of the roof slope are cut.
Before you study the information on how to competently lay and equip a seam roof, you should familiarize yourself with the basic terms of such a design.
Seam roofing is a special modern coating, where compound adjacent structural parts produced by means of special folds.
The picture is one of the elements of modern roofing, in which all edges and edges are previously prepared for the arrangement of the seam connection.
Among the main advantages of the roof can be noted possibility of long-term use of the coating based on the presence of a modern anti-corrosion coating.
The seam elements are lightweight and have a smooth surface. Due to this, snow and water do not linger on the surface.
In this article, we will analyze in detail how to make a seam roof from iron sheets and how to properly prepare a crate for a roof using a special technology.
The device of a seam roof begins with the choice of fastening - a seam. The folds can be standing and recumbent, and they differ in that with the help of horizontal folds it is possible to effectively connect all the elements that are in the same position. Standing elements can connect the roof along the entire length of the slope.
Folds are characterized different types produced compound, which can be single and special double. In the first case, this is one classic bend, the double one is distinguished by the possibility of ensuring maximum tightness. Such folds are used in those areas of the roof where there is a danger of moisture accumulation, from leakage, which is typical for the gutter.

Seam roof tool
For proper installation, many tools, different nozzles for them and other elements may be required. Before installation, it is worth preparing the following roofing tool for seam roofing:
- All possible measuring devices - plumb, level, levels.
- A tool for detecting the difference between the height of all surface points in relation to one or another set level. Equipment is required to measure the possible rise in level.
- Manual and more modern electric scissors, which are needed for cutting and accurately cutting out roofing elements.
- Nibbler for the implementation of the operational process of sharpening.
- Hacksaw and construction jigsaw for efficient device crates.
- Standard Bulgarian.
- Household drill and puncher.
- Mounting gun for pressing out. Rubber and wooden mallets.
You can cut the rebate panels using angle grinders. The main thing is that all untreated areas are carefully protected from sawdust, and the cut points must be treated with special anti-corrosion compounds.
Seam roof installation tool
roofing cake
The seam roof cake is characterized by a special multi-component system, which, in addition to the roofing itself, consists of various other elements. This can be attributed, as well as high-quality. Hence the name roofing cake - it consists of a large number of layers. If the cake is arranged correctly, a lot of different problems can be avoided. This is an ideal opportunity to prevent the appearance of icicles, the process of accumulation of condensate and heat loss.
NOTE!
The arrangement of the pie requires special attention, since errors in the design process of a particular layer will seriously reduce the overall strength indicators as well as structural durability.
Of serious importance in the process of designing and arranging the roof is competent. It removes excess moisture from all the roofing cake. To remove water through the membranes into the equipped ventilation, it is worth leaving several holes in the roof during installation. A wooden crate will cope with this process perfectly.
roofing cake
What is a clamp and why is it needed
In the process of arranging a roofing seam covering, fastening devices such as clamps are used. In fact, This special device, which is intended for fixing roofing sheets. You can not use nails, which can violate the integrity and complete tightness of the coating.
The use of a clamp greatly simplifies the installation process of roofing, ensures the overall durability of the system. Finishing the roof with similar elements makes it aesthetic and as tight as possible.
Lathing under the seam roof
Seam roofing is fastened strictly to the preliminary installed crate. This will help prevent sagging of steel sheets, but only if the required pitch range is fully met.
As a crate, materials such as:
- Galvanized metal profile.
- eco friendly wooden beam 50 to 50.
- Board 100 by 32.
These elements are attached strictly from below and upwards, that is, from the cornice part to the roofing ridge. If a metal crate or a discharged wooden crate is installed, it is worth using a high-quality anti-condensation film before installing it on the rafters. When using a special continuous batten or other completely continuous base, a special category film will be required throughout the decking.
Lathing step - 20 centimeters, it is allowed to use a step in the range of 20-40 centimeters.
The material provides the following benefits:
- Permanent device ventilation duct , which will remove condensed moisture that appears on the reverse side of the roof, made of metal;
- Effective preventing destructive corrosion metal elements, as well as rotting wood elements;
- Significant noise reduction from precipitation.
Where the installation of roof nodes - valleys, roof cornices, as well as connections and junctions to various protruding elements of the structure, the second crate profile element is mounted. This gives increased strength and rigidity to the installed panels.
Additional elements
The design of the crate is made even, the presence of recesses, as well as various protrusions, is unacceptable. Roof ribs and standard ridges are mounted straight, and the lowest board is also straight.
If the crate is made of wood, preference should be given to such types of wood as aspen, spruce, fir, pine. Humidity of boards should not be more than 12%. To give wood strength, for its durability, the material should be impregnated with special antiseptics.
crate
It is possible to significantly increase the operating time of a wooden crate by coating it with drying oil. A structural steam-diffusion film is laid on the already finished crate. Its durability, as well as the quality of the entire roof, as a whole, depends on the competent arrangement of the crate. Even relatively a slight deflection of the sheets is able to weaken the density of the mounted folds.
If an insulated roof is installed, high-quality ventilation must be provided without fail. In this situation, first a counter-lattice is placed, a special hydro-windproof membrane is mounted under it, and only then the crate itself
Seam roof slope - optimal and minimum
In the process of arranging a seam roof, it is important to observe the slope of the roof. It can be optimal or minimal. The choice is made on the basis of the architectural and planning features of the building.
The optimal slope is on average 10-15 degrees of inclination.
In the higher part, builders take out ordinary living quarters, in the lower part, utility rooms and bathrooms. The optimal slope of the roof can be steeper, then the angle of inclination can be 20-30 degrees.
With regard to the minimum slope of the seam roof, they are recommended for certain categories of roofing. The design features of such a roof make it possible to cover any size of roof without problems, as long as they are flat.
Roof slope
In this case, the angle of inclination does not go beyond the 15-degree indicator. The type of material used directly depends on the slope angle. suitable for roofing at 20%. ideal for roofs with a slope of 5%. In all cases, when installing the coating, small overlaps must be taken into account. A special sealing tape must be laid in the joints.
Seam roof waterproofing
When installing the roof, it is important to pay special attention to the connecting seams. This is one of the most important indicators that has a direct impact on ensuring the sealing of the roof and seam.
By using a special coating equipped with a self-locking seam and a double standing seam, a high level of tightness can be achieved.
It is equally important to use a high-quality fastener, that is, nails, self-tapping screws and a seam roof clamp, made of high-quality galvanized steel.
They play an important role in ensuring sealing, the longer they will retain their quality, preventing leaks.
The correct installation of hydro and thermal protection under the roof completely reduces the risk of rapid wear of the roofing. High tightness rates will be maintained for decades.
Seam roof installation - instructions
The construction of a structure from a professional point of view must be carried out under the careful observance of certain conditions, as well as the sequence of actions established by professionals.
Do-it-yourself seam roof:
- Production of special paintings that will be used to cover standard slopes and other details, such as overhangs and roof gutters. For this purpose, blanks or paintings are produced according to a previously prepared drawing and scheme.
- The edges of these parts must be bent, that is, they are prepared for use with seam joints.
- Raising previously prepared paintings to the structure, their connection with special standing folds. Pre-installed paintings are securely attached to the wooden crate with clamps. One side is brought into the fold, the other is attached to the beam of the mounted crate.
- On final stage aprons are mounted on all holes present made from high quality steel.
- If you have any questions about the installation of the coating, we recommend that you watch the video below.

Seam tie
CAREFULLY!
In the process of using sheets 10 meters long, it is worth fastening them securely to the crate installed on the roof, using clamps of a special floating type. Only in this way the roof will not lose a high level of tightness at all, even with temperature changes.
Installation of snow retainers
Roof installation work involves the installation of special 
fences. This is a kind that is able to solve a huge number of different problems.
By means of fences, snow can be reduced from the roof. This will completely prevent the possibility of damage to health and property. It is possible to protect growing plantings next to the building.
Fences seriously improve working conditions in the process of performing work related to roof maintenance. Snow guards effectively prevent possible damage to the drain.
It is important to carry out such roof railings in full compliance with the requirements officially fixed in SNiP 21-01-9. The documents state that fences must be present on roofs with a slope of 12 degrees and with a total eaves height of 10 meters or more.
Snow guards for seam roofing should not only be reliable and durable, but also attractive in terms of their external characteristics. It is advisable to ensure that the design is fully consistent with the overall style of the house. For this, special profile pipes or similar materials. All parts of the fence should be painted with a special polymer paint on a special powder basis.

Conclusion
If the work is carried out strictly in compliance with the listed rules and conditions, the seam roof can be rightly classified as a durable and at the same time unpretentious coating during operation. Roofing can be installed without problems in private buildings, as well as in public buildings.
In contact with
CLASSICA and ELEGANT are fastened directly to the lathing with 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 seam are fastened to the lathing 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).

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 batten: galvanized metal profile PSh-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 lathing, 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, it is recommended to lay an anti-condensation film before installing it on the rafters. 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:
- the device of a permanent ventilation duct to remove condensed moisture that forms on the inside of a metal roof;
- 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 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, arranging cornices, ridges, finishing chimneys, ventilation shafts for roofs from standing seam panels at various slopes are recommended to be adopted in accordance with SP 17.133330.2011. At minimum slopes 3°-10° it is necessary to apply seam roof sealing sealing tape Outline 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 an organized drain is provided from the roof, then before installing the roof deck, it is necessary to fix the gutter holders. They are fastened with a step of no more than 750 mm to the rafters or the bottom lath of the crate (see installation of the 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 the installation of seam panels, self-tapping screws 4.8x22 with a press washer are used, and for component elements and in places where the panels overlap along the length - 4.8x20 (for the metal sheathing of the seam roof) or 4.8x35 mm (for wooden crate) with 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 lathing) 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) cut the lower part of the "lock" from the 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) execute interlock connection panels 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 with roofing screws with a sealing gasket.
5.5 Skate
The ridge is installed on the upper edge of the slopes on the finished roofing. The upper part of the 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
In places where the roof adjoins the wall, pipes and dormer windows, a wall profile is installed. The profile is superimposed on the seam 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 rectangular pipes protruding from the roof are framed with 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 onto 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 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. The construction of a drainage system on the north side of buildings should be avoided in order to prevent it from 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 per downpipe, the gutters can be installed with a zero slope, with a larger catchment area, the slope of the gutters can be up to 5%.
step 1 - Installing the gutter holders
The installation of the drainage system begins 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. Having determined for yourself the 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. The length of the connecting pipe is 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 at the wave deflection point with self-drilling galvanized bolts 5.5x25 mm for metal sheathing and 5.5x60 mm for wooden sheathing. It is forbidden to fasten a roofing fence to one seam picture. Between themselves, the sections of the fence are bolted (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 are fastened through the metal tile and rubber sealing gasket to the roof sheathing. 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 a large amount of snowfall, the installation of a bracket rod is provided. 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 on the selection of the number of brackets, the brand of the fastener, depending on the design of the seam 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 cross-section with a diameter of up to 330 mm (with an outer surface temperature of up to 130) ° Master Flash roof seals are used.
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 by various methods (immersion in a container with a solution, brush application, spray application).
10. Tools for the installation of seam roofing
- Screwdriver with hexagon socket 8 mm.
- Electric nibbler or nibbler.
- Manual roofing scissors.
- Mallets (wooden, rubber).
- Hacksaw, jigsaw, hammer (used in the construction of rafters and battens).
- Angle grinder ("Bulgarian"), puncher, drill, gun for pressing out sealant (used when installing a wall profile).
- 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.
Use as ridge or valley seals polyurethane foam is strictly prohibited!

For more than 10 years, the specialists of our company have been manufacturing and professionally installing seam roofing from different metals on turnkey roofs of any complexity. The price for the installation of a turnkey roof is from 500 rubles per m2. In addition to the installation of the seam roof itself, we carry out work on the installation of all the accessories necessary for the proper operation of the roofing system: drainage systems, soffits, snow retention, wind vanes, etc. We will help you choose the material for the roof of your own house, as well as for covering public buildings.
Seam roof installation rules
Installation of a seam roof on a turnkey basis is a rather complicated and time-consuming process that requires a fairly long work experience and highly qualified specialists. In order to start making a seam roof, you need to purchase material - a metal strip. Its amount required for the installation of a seam roof can be roughly calculated as the roof area multiplied by one and a half. For a more accurate calculation, clear dimensions of all roof elements will be required.
- Work on the installation of a seam roof begins with the preparation of the base. As a rule, a crate with a distance between the boards of 50-150 mm is quite suitable for any type of metal. But such soft types metals, such as copper or aluminum, can, under the influence of snow load and heating, display the entire crate on its surface. Therefore, under copper and aluminum, a crate made of FSF moisture-resistant plywood (thickness from 12 mm), OSB boards (thickness from 11.3 mm), tongue-and-groove board (thickness from 25 mm);
- When the solid crate is ready, work is carried out on laying the lining carpet under the roofing. Since condensation-dew forms on any metal due to temperature differences, a continuous crate must be protected from moisture. The lining carpet successfully copes with this. If the crate is not continuous, then there is no need for its waterproofing from the metal;
- It is important to remember that each type of metal from which the roof is made needs its own fasteners. For example, fasteners made of copper and stainless steel are used for copper, for titanium-zinc and aluminum - stainless and galvanized steel, etc.;
- Seam roofing begins with the manufacture of all elements - picture panels, shaped strips, gutters (if a wall gutter is needed), embedded elements, type-setting frontal and gable strips. All components of the seam coating are made based on the width of the metal strip. On the panel there is 100% of the width of the tape, on additional elements from 20% to 100%. If you need any non-standard cornice or frontal plank that requires multiple cutting of metal, then this issue is agreed with the customer or architect;
- Installation of the seam covering is carried out starting with hooks for gutters, embedded strips on the cornices and ends of the roof, and also, if the roof is insulated, from the installation of a drip for condensate drainage. Next, a frontal board, gutters, cornice strips, valleys are mounted. Then panels-pictures, ridge and end elements are installed. The process of installing a seam roof is completed by installing wind vanes on pipes and connecting to vertical surfaces;
- For seam, as well as for any other, special security systems are needed. These include snow retention, walkways and roof ladders. The snow retention system prevents avalanche-like snow from the roof, and walkways and ladders help specialists of the facility maintenance service to move along the roof.

Our team performs roofing installation services in Moscow and the Moscow region!
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, are manufactured (rolled) by our company's specialists on our own German equipment from SCHLEBACH, 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. Openings at chimneys and gas pipes, including ventilation ones, are covered with aprons made of galvanized steel.
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 "pictures" are made directly on construction sites from metal delivered in rolls, and can have a length equal to the length of the 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.
Benefits roll technology(double standing seam):
· 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 seam of longitudinal seams of adjacent roofing sheets and, as a rule, the complete absence of horizontal lying seams);
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, as 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 peculiarities of the roofing, made in click-seam panels, is the possible presence of waviness in the paintings, which is caused by the specificity of 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 leaks if the roofing pie is installed with deviations from the norms and SNiPs.
When installing a roofing pie, it is important to observe the technically competent execution of the 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. With an insulated roof, it is necessary to use not only a good multi-layer waterproofing membrane, but also a high-quality vapor barrier film mounted under the insulation. 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 failure of truss structures. 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 seam paintings.
