What is the folded roof?
A special type of roof - rebated - this is the type of roof where roofingattached to the substrate not by nails or screws (which are potentially dangerous in terms of leakage), and is fastened by bending the edges.
Seam roof very popular in Europe, especially Southern, but in Russia, Belarus, Ukraine and Kazakhstan is rarely used. The reason - the belief that with strong gusts of wind or snow in the winter, seam weld can break up, leading to roof leaks.
In this seam roofing is made almost the same technology and of the same material as the decking profile, and therefore in no way inferior to him as!
As the attached seam roofing?
Seam roof requires the minimum roof inclination within
10-30 degrees to the horizontal. two types of folds are fixed in SNIP:
- standing (Double and single)
- recumbent (Double and single)
Most convenient for installation seams - single standing, such constructions are also called snap-on. But if you live in a windy area, it is best to choose a sealed double standing falets.
Recumbent folds are good for removing water from the roof. Their connection extends parallel to the eaves, but the stand-seamed joints characterized by a compound of parallel rafters.
However, to understand the attachment scheme convenient visually:
Again, many fear seam roof for any leaks and destruction from wind or heavy snow, but another disadvantage is its high cost of installation.
