Errors in the construction of the roof, after which it will have to shift
The construction of the roof - the responsible thing. roof cost about 30% of the cost of building a house. Let's talk about the common mistakes that make Roofers and how to avoid them.
The choice of roofing
If the slope of the roof has a slight bias, it is impossible to use a tile or slate. If the winter a lot of snow, so that the roof will not be effective.
Choose the material not only in appearance, but for practicality and durability. Not recommended for roof edging board with bark. The crust will live larvae, beetles, which eventually damage the tree.
Assembling of tiles
Not properly stacked sheets of material one over the other. Proper installation starts from the top down. tile sheets are overlapped in a checkerboard pattern. The top sheet is fixed, the next sheet is lifted and secured under it.
thermal insulation
During the construction of the roof to the rafters placed under-roof membrane. Between the rafters is necessary to lay the insulation. Then make the crate and put roofing material. Not correct installation of the membrane lead to the fact that in the insulation will accumulate moisture. The film itself is sold in a roll and its front side is folded inside.
lathing
From the qualitative performance will depend purlin roof appearance. Correctly done work will affect the reliability of the roof and weather resistance.
Not exactly stuffed crate will prevent a flat tiling. Sheets are not dockable.
The mistake is and what makes a big gap between the rafters. Consider the weight of roofing material in the construction of the roof.
tile cutting
Some are beginning to cut composite shingles grinder. Such materials should be cut with scissors or guillotine metal. Bulgarka may damage the decorative covering and protection. This will necessarily lead to corrosion in the places where they made the cut grinder.
The most vulnerable spot
Roofing vulnerable spot - the joints. Pay special attention to the adjacency of the material to a chimney, walls, roof window ventilation. To protect output through the roof decking circular tube roofer uses some aprons - caps:
abutment - too weak spot roof. Error - bonding the sealing tape to the surface of a roofing material which is not cleaned from dust and dirt. The material will move away from the roof. To be used for special junction. presser bar (rail).
Seal the apex
This material needs to avoid blowing out the snow and moisture under the ridge lath. Seal better than the one that swells up in the air (self-expanding). This is a universal sealant which is capable of filling the smallest gaps.
