To distinguish the folding roof from other types of coatings is quite simple. This is a characteristic pattern of longitudinal-transverse seams with a rebate. Reliability of rebated joints of the roof has been checked for years. Try to break this connection without damaging the integrity of the structure. Surely, you probably will not succeed. So, the fineness of the installation or what you need to know when installing the roof seam.

What is a seam roof
Among the various types of metal roofs special place is occupied by the seam roof. The name "seamed" roofing was obtained by using sheet cover elements or so-called "paintings", which are connected by means of a fold.
Specific attachment system, hidden under the rebate, reliably guarantees the sealing of the roof. Therefore, the roof leakage is completely absent. What is the secret of the full sealing of the rebated roof? The whole secret lies in the rebate - the form of the seam, the bend of which is formed when joining the sheets of material.
Stiffeners formed by folding create a directed movement of melted water along the longitudinal line, excluding their lateral drainage.
Let's add that the installation of the roof seam is possible on the roofs of any configuration and complexity. The price of the folding roof is composed of the following parameters:
• prices for roof panels (depending on the material selected)
• the cost of accessories roofing (snegozaderzhateley and snegorezov)
• carrying out roofing works.
Falsi roof perform or roll up manually, or by special sealing devices.
Shroud of the roof
Folded joint is an integral joint of sheet blanks, which are pressed by bent edges. Folding connection is a sufficiently strong connection, which can not be disassembled without disrupting the integrity of the elements.
It is necessary to distinguish the following types of folded joints:
• recumbent
• standing (single or double)
• self-locking.
During installation, the long edges of the strip of sheet that runs along the roofing slope are connected by folds to stand-by ones. The horizontal edges of the strips of the sheet are joined by recumbent folds.
The recess is used as a closing, so it is used for products that are not subject to increased strength requirements.
Standing folds (single or double) are used for cross connection. The height of the rebate can reach 25 mm, a thickness of 0.6 mm. In this case, the created fold provides the system with additional rigidity.
The greatest tightness creates a double standing seam. In the countries of Europe, the folded roofs of houses are performed exclusively using a standing fold of a double or self-locking system.
What materials are used for the seamed roofing
The following materials are used for the production of seamed roof sheets:
• copper
• Aluminum
• galvanized steel.
Roofing copper can have a textured pattern. Supplied by the manufacturer in the form of roll or sheet products. The joining of sheets is carried out with the use of a fold and by soldering. Copper roof can be confidently considered "long-lived", because the service life is hundreds of years.
Aluminum roof seam can also have a textured pattern. The sheet is joined by folding. The life of the aluminum roof is up to 100 years.
Zinc-plated steel for roofing has an additional coating of polymeric compounds, giving the material attractive decorative qualities. Distinctive qualities are high corrosion resistance and long service life.
The technology of installation of rebated roofing
What you need to know about the technology of mounting the rebated roof? When using the installation technology, the recommended roof slope should be up to 14 °.
The beginning of the organization of work with the rebated roof must begin with the installation of the eaves and the catchment system. At the first stage, the catchment system in the form of gutters should be installed with a slight slope, ensuring the flow of water into the receiving funnels. Roof elements are designed for mounting on ramps:
• produce sheet marking for the parts according to the installation project
• Cut the sheets into markings and join them into paintings
• bend the side edges of the connected elements.
In the second stage, the prepared panels are lifted and directly connected to the roof by a standing seam.
The roof paintings are laid out on the slope with strict verticality relative to the lower edge of the roof.
Then, on the crate installed to this moment, the roof panels are fixed using the clamps.
Roofs are arranged on the crate, consisting of bars (50x50mm) on a solid foundation or in increments of 25 cm.
Wood laths are pretreated with an antiseptic.
The step of the battens should be carried out. Otherwise, the sheets of material may be deflected and joint deformation may occur.
One end of the clamp in the form of a strip is set at the point of bending in the standing seam. The other end is attached to the beam of the crate. When constructing a seam roof, it must be remembered that the main roofing sheets and clamps must be of the same material type. Pictures of the roof should protrude 5 cm above the ridge. The forming junctions, as well as the connections of the remaining elements of the roof, are smeared with a silicone sealant. More information about the installation of the roof is presented here.
Which tool is used for the rebated roof
To close the rebate when installing the roofing panels, use a hand tool (frame). The construction of the frame material completely eliminates damage to the painted metal sheets. Hand tools for roofing seam is used on steep roofs and in hard-to-reach places (valleys).
With the use of a hand tool, the crimping density with double folding of the fold with a grip length of about 22 cm makes it possible to achieve complete tightness. Therefore, without the use of this type of tool is indispensable.
So, what are the attractive seamed roofs in contrast to existing structures? Of course, this is the ability to withstand loads and attractiveness. Compliance with the laying technology will ensure the roof of the house, the roof of which is installed by oneself, a long life.
