Installation of seam roof: roofing pie arrangement and installation of standing seam panels

About how to choose the material for the standing seam roofing, as well as what kinds of rebate considered the most reliable, we wrote the first part of this article. Today we talk about design features a metal roof and on the technology of its installation.

Guaranteed to protect seam roof from condensation, strains and depressurization help compliance with certain rules, everything concerning roofing pie, features styling of the roof covering and its consistency installation.

In this article, we consider the following questions:

• What are the elements consists cake seam roof.
• How to arrange the eaves standing seam roof.
• Sequence and assembly technology standing seam panels.
• Construction of valleys and joining seam roof.

If building a house begins with the foundation, the arrangement of standing seam roof begins with the creation of roofing pie, which protects the attic space of the condensation and cold. Thus roofing cake is reliable protection against noise caused by precipitation.

Paul T. (User FORUMHOUSE):

If the roof insulation of 250-300 mm (I 300), then no noise can not be heard (unless, of course, will not go hail the size of an egg). The only thing where I can hear rain (and the weak), so it is in the bathroom, where the suspended ceiling is installed.

To obtain the required insulation thickness, insulation can be placed in several layers (between the rafters and below).

Roofing pie seam roof consists of several layers:

Let us examine them in detail.

Supportive crate - lower wooden slats, which are borne vapor barrier film, and the insulation.

Steam insulation film - a special material that prevents moisture from penetrating into the insulation space.

Rafter - wooden beams cross section 200x50 mm. The distance between the rafters - 1.2... 2 m.

As the insulation is most commonly used mineral wool. Insulation is placed between the rafters directly on the insulation film, which, in turn, is supported by the lower crate.

Waterproofing - a special film which is moisture in one direction only (bottom-up). Waterproofing does not penetrate into the underroof condensate heater, but skips the humid air that accumulates in the mineral wool layer. Waterproofing film is a diffusion (breathable) membrane, which is sold in DIY stores.

berd80(User FORUMHOUSE):

You can spread out the diffusion membrane can use a special three-dimensional membrane (only well worth it). By all accounts did not come on this issue.

Waterproofing spreads across the trusses in the - direction from below upwards (starting from the eaves slats, in the direction of the ridge). By wooden rafters film clips fastened (using stapler). Individual strip of waterproofing membrane laid overlapped (overlap width - 100 mm). On gable eaves overhang is necessary to provide the film (the width of the overhang - about 150 mm).

The film should not be under tension, and the allowable deflection of the membrane between two adjacent joists is 35 mm.

In no case can not be as a vapor barrier and waterproofing use one and the same material. Especially, you can not rearrange them. All this will lead to moisture accumulation in the insulation or, on the contrary, in the room. Mold development and the consequent destruction of building structures in this case - are guaranteed.

Kontrobreshetka - 50x50 timber, which is nailed to the rafters over the waterproofing film. Kontrobreshetka allows to create an air gap between the waterproofing and rebated coating.

Under kontrbrusya is enclosed special sealing strip, which seals in the field Gvozdeva compounds and safeguard the insulation against moisture.

Lathing - transverse strips nailed to kontrobreshetke through a certain distance.

Arhios (User FORUMHOUSE):

Bar 50-50 (kontrobreshetka) nailed along the rafters, and for them (across) - 100h25 strips with Extension (crate).

Kontrobreshetka provides ventilation of roof space that gets rid of condensate formed there. To kontrobreshetka guaranteed to perform its functions, the eaves standing seam roof should be made as follows:

Effective ventilation of roof space provide a ventilated skate.

And ventilation mesh tape of PVC, which is stretched between the crate and the front eaves board.

These two elements provide a constant blowing of roof space.

Special attention should batten pitch - the distance through which nailed the cross bar. In accordance with the rules of arrangement of the metallic seam roof (SP 17.13330.2011) the distance between the individual batten bars should not exceed 200 mm. This allows the human foot, stepping on the roof covering, based directly on the two boards, which protects the metal against deformation.

Along the edges of the roof (in the field of roof overhangs) as well as created in gutters solid wooden flooring width of not less than 700 mm.

Some users of our portal is recommended to do a solid batten seam over the entire area of ​​the roof, that, in general, is not an error (especially if it coincides with the recommendations of the standing seam manufacturers paintings). For example, according to the technological requirements of a solid crate mandatory "spreads" under the zinc-titanium roof.

The solid crate - relative concept. Between each crossbar lathing necessarily left a small gap (less than 10 mm), which will compensate for the thermal expansion of the timber.

The workpiece materials

If you decide to make painting seamed roll or sheet metal, is without brakes and Fold machines can not do. Acquire such equipment for private construction - not advisable. But this does not mean that you must manually bend the metal.

vasilpolt (User FORUMHOUSE):

It is better to use the service team that has a machine for rolling patterns. The quality of the roof in this case, would be better than if you stick to hire hands. There is even a separate service - "Rent a picture." Virtually every roofing company that has the necessary equipment to offer it to their customers. Try searching in your area.

Also, with the necessary additional elements can be manufactured using a plate-bending equipment. What is needed for the construction of transoms - it depends on the design features of the roof.

The photo shows typical profiles, geometry and dimensions of which may vary depending on the characteristics of a particular roof.

Device and installation of eaves node

Installation of seam roof start with everything eaves. Immediately draw attention to the fact that the eaves are available in different versions. It depends on the design of drainage system. Drain systems, in turn, can be suspended or wall drains.

Eaves trough with outboard has transverse folds, so that the roof is a more airtight and easy arrangement. Given that snow and ice can easily damage the suspension gutter, roof surface with long ramps have to be equipped with additional elements for snow retention.

with wall drainage system and flat upper tides it has a more complex structure, and its installation is better to trust an experienced tinsmith. The stiffness of the system with wall gutters order of magnitude higher than its analog with outboard troughs.

Roofer1959(User FORUMHOUSE):

Regarding the gutters if they are correct, then any good. Wall - safer in terms of rigidity, and for his safety, I can vouch. But there is a weak spot - eyeliner paintings (especially if single fold). Suspension devoid of disadvantages, but its stiffness under certain operating conditions may be questioned.

There is no consensus about what a drain should be installed complete with a standing seam roof, no. Whatever option either liked you personally, Cornice assembly will have to equip according to the same principles.

Installation of cornice assembly begins with the installation of stalactites and ventilation tape.

Lower Cornice profile - "drip" (on which will drain the condensate formed in the roof space) - is mounted on the rafters and covered with a waterproofing membrane. This is done at the stage of arrangement of roofing pie.

Between the waterproofing drip and should apply a thin layer of adhesive or roofing sealant.

Sometimes the lower drip is not used at all: for example, if the roof space is well ventilated (with the help of a ventilated ridge - top and ventilation tape - from the bottom). But it is better if it is still installed.

nekorsakov(User FORUMHOUSE):

The first step is mounted on a plastic grid gap between the crate and head-board. grid on top of stuffed Cornice strip, which is attached to the crate roofing galvanized nails, hammering them in a checkerboard pattern. Strips mounted on the stretched cord along the eaves, and a mesh was attached closely on the edge.

PVC mesh protects the under-roof space from insects and debris. The distance between the bar and the eaves ventilation grid should be less than 2... 3 cm.

If a part of the roof is planned to use the suspension gutters are kindly requested to consider the way to install curtain hooks for the drainage system. So long curtain hooks that attach to the top of the crate, the plant directly under the eaves bar. Under each hook is necessary to make a hole in the surface of the crates. Otherwise seamed pattern along the edge of overhang will waves.

To give added rigidity eaves, under the eaves lath metal roofing installed crutches.

Crutches cut into the deck is flush with the surface of the purlin (in analogy with rainwater hooks) and secured thereto with screws.

The distance between two adjacent crutches is 60... 70 cm.

Standard crutches are commercially available, while they may well be made independently. It is most commonly used for the manufacture of steel strip crutches - 40x4 mm. desired size billets are welded together and then drilled and subjected to rustproofing (processed primer).

Standard T-shaped crutch for eaves has a width of 100 to 200 mm and its length depends on the design features of the roofing.

Spikes are used to enhance the eaves, as well as other elements of the roof. Therefore, they may have different geometries, which depends on the direct product destination.

Rebated themselves already are ribs. Therefore, on roofs with roofing suspended gutters crutches may be used, and may be replaced by strips of galvanized or painted metal. They are installed along the eaves. Steel strips are arranged on top of cove or strips placed under it - depending on the geometry of cornice profile.

nekorsakov (User FORUMHOUSE):

Before installing standing seam patterns need to install additional metal strips, reinforcing the rigidity of the overhang and forming a projection (50 mm), for which then fastened and crimped curved edges.

After completing the arrangement eaves node, you can proceed to the next stage of work. But first, a little talk about the construction tools.

Tools and accessories for installation of standing seam patterns

Mallet (plastic, wood or rubber) and a hammer - tools for the formation of creases and other elements of standing seam roof.

Shlyazen (mandrel, the mandrel-vane) - a device that is used to form the ridges and improvement in the field of locks adjacencies (valley, detours ventilation ducts and chimneys, etc...).

Straight and angled pliers (large and small) to form a standing seam bends and other complex elements and roofing.

Crimp roof frames - serve to crimp the L-shaped and double folds. In fact, the two frames are used to close the double-fold, because of its rolling is carried out in two passes: Mr. frame closes single standing seam during the first pass, and the frame for closing double fold is used during the second pass.

There are also the framework for the hem of roof overhangs. They are used for installation of various paintings (including quick-release).

Set of scissors on metal with different angles of cut.

Cut panel grinder or other abrasive tool can not be! This destroys the protective coating material.

Mounting rays roofing roof in Example gable

Fitting roof rays starts with the installation starting panel. The key difference between the starting panel by the ordinary panel consists in a special profile geometry, whereby the picture can be fixed to the crate from two sides.

The pitch between adjacent fasteners (capping) is 40... 50 cm.

Clamps must fully replicate the geometry of the bends, which are available on the shelves of the side rebate pictures. Such fasteners can be made independently, and can be purchased in the construction market.

If the length of roofing rays exceeds 6.5 meters, experts recommend the use of mobile clamps, which can compensate for the possible deformation of the thermal expansion of the panels.

After setting the starting picture to Install the rest of the roof.

nekorsakov (User FORUMHOUSE):

Next to the picture placed and fixed is placed next, which overlap (curved edge) closes Gvozdeva shelf previous panel. Both paintings are crimped to the castle along with the already installed (hidden) clamps. The result is a very safe and tight connection, because the whole fixture is closed metal sheets.

Crimp rebated compounds produced in the standard sequence. At first, using the horizontal frame for closing the lock, the first crimp made. Then, using the frame for closing double fold is made the second crimp.

Finishing the picture cut to size (so as not to extend beyond the gable overhang), turned in, and clamps attached to the crate. Pediment overhang subsequently closed special profile.

Foam soundproofing tape, occurring at the time of rain that can enclose a seamed panel along their entire length, additionally protects the room from the noise. The tape is cut to size and attached to the crate stapler.

We have described the sequence of installation of paintings produced on faltsegibochnom equipment according to individual sizes. Installation of self-locking of the roof has its own nuances.

For example, during the installation of quick-release panel roof screws are used instead of clamps, which are screwed into the lath Gvozdeva rebate pictures. On Gvozdeva strips are elongated holes, which help to compensate for the thermal deformation of the panels.

For fixing clamps and quick-release panel to the wooden crate, use galvanized roofing nails or screws to press the puck (wood), which have a flat hat.

To self-locking roofing wave did not go in hot weather, screws must be screwed exactly in the middle of the oblong holes. Thus, fully tightening the screw, it should be unscrewed approximately a quarter turn (to the panel could shift slightly due to thermal expansion).

Making the roof to the ground eaves

Combs rebate paintings, located in the ground eaves should be trimmed (literally 2... 3 cm).

Thereafter, the remaining (protruding) part of the picture podognetsya easily under the eaves to form a reliable and hermetic Cornice protrusion.

Not necessarily completely remove an edge portion of the ridge. It can bend to form at the end of seam trim bezel blank.

Installation of the side end strips

Introducing setting circuit gable side profile.

Where:

• Brus, on which is mounted a wind strip (beam dimensions are selected based on the geometry of the wind profile).
• Roofing screws "metal-wood".
• Side strap end.
• Start / finish panel standing seam roof.
• Screws with a press washer.
• Capping.

Roofing rays on the junction end straps are connected as follows.

Installation of ventilated skate

Basic elements of the ventilated skate - is: upper ridged profile louver and the supporting elements.

Construction of a ventilated skate, is simple and reliable, the user has mounted nekorsakov.

Upper Cornice profile was purchased ready-made. The lower (reference) profile is made of galvanized steel sheet bending equipment. Its perforation was made directly on the construction site.

nekorsakov (User FORUMHOUSE):

Decided bottom (abutment) of the strip between the start and crate pattern, does not further fixing. On top of them mounted the upper strap (with an overlap to some). Support bar in the end did not hold separate screws, and a roofing sheet, fixed clamps and compressed with adjacent sheets. In this embodiment, the perforated wall mounting support bar turned deeply retracted from the edge that both aesthetically and functionally it seemed to me better (away from the "aggressive" with its external environment precipitation).

bypass pipe

Chimneys and ventilation shafts - protruding elements, crawled in the regeneration of seam roof requires specific skills in the performance of sheet metal. Consider a standard version bypass the example self-locking of the roof. It will be able to mount any nonprofessional roofer.

The owner of the sofa (User FORUMHOUSE):

Blue color means the standard pattern latch, red - cut off from the latch pieces of green - just metal. Red and green cut out and done the standard apron (abutting strip), on top of the picture to fit it vzatsep, bottom apron rests on the bottom of the picture.

In practice, the bypass as follows:

From standard standing seam panels are cut to pieces of locks (in the diagram shown in red). Of these abutment strips are formed (lateral aprons) which on one side adjoin to the tube wall, and on the other - are latched with neighboring patterns. The space between the side aprons close adjacency strips (top and bottom) that do not have a latch. On the top rod is a hook, on which rests a picture suited to the chimney top. Bottom bracket with a hook rests on the bottom of the picture.

Apron abutting to the walls of the tube are closed roofing sealant.

Panels having a rolled double fold, in place bypass pipe mounted in a similar manner.

All four of the apron, in this case, are connected with the adjacent paintings immobile and standing seam.

device valley

Immediately turn our attention to the arrangement of the base to the requirements under the bar of the valley: the base will be here for a solid wooden crate.

Design metal adjacencies should ensure maximum tightness in the joints of the roof of the two ramps. Therefore, the bar must be fixed to the roof valley crate clamps (in any case no screws), and paintings junction to the roof valley should be closed double seam.

The resulting ridge is recommended to bend, forming at the site of landfall recumbent fold.

The owner of the sofa (User FORUMHOUSE):

Not the best solution - honeycomb pattern (as well as the valley) with screws. That's right - do seam (hem) on the edge of the picture and make it to the appropriate rebate valley. That will have a recumbent fold. overlap size - about 30 millimeters. Flagon, in turn, is attached to the crate clamps.

These rules are relevant for standing seam patterns and profiles made from sheet steel by roll or sheet bending / Fold equipment. Mounting the abutment on the "roof of the self-locking" should be guided by the instructions and recommendations of the manufacturers of roofing panels.

Wall connection

Junction with wall - design element, without which no cost, no complex roof. Such abutment has a simple construction and executed with a special profile.
