Principles of correct calculation of
The main principle is to calculate the amount of required material with a margin. At the roof of the roof there are unused pieces of coating. This does not mean inability to plan purchases, it is more evidence of entrepreneurial entrepreneurialism.
The gable roof has the shape of a triangle, its area can be easily calculated using the Pythagorean theorem. The sides of such a roof are the width of the overhang and the length of two skates. This is the absolute area. Such a roof is advantageously combined with such materials as plywood, lining carpet. Take materials with a surplus of about 5 percent.
Consider a specific example.
The roof area is 40 square meters. The plywood layer has the parameters 1.30 / 1.30, multiply = 1.69, then 40 divide by 1.69.We get 23, 67.
It is necessary to consider different versions of materials having their own standard length and width parameters. The plywood has also the parameters 1.29.Metal tiles offer their choice.
Before buying, please read the description on the packaging. The area of soft tiles is given in all price lists. The purchase of building materials is worth with a margin for overlaps and features of the roof of each type of coating.
With a package area of 3.5 square meters, 40 / 3.5 = 11, 43 packs are needed( with a 4 percent reserve, you need more packs).

Calculation for a multi-pitched roof
Take a multi-pitched roof with:
- 8 triangular ramps
- 4 trapeziums
- 4 trapezoids with non-parallel bases
Roof area 260 square meters. Roofing is mounted with plywood. It is strengthened by heat and waterproofing, underlay carpet, it is firmly covered with soft tiles.
Consider in order:
- We measure plywood 260 / 1,69 = 154 + 12 = 168 sheets
- Waterproofing we buy one roll more
- Lining carpet. We buy a few percent more in view of the stock. Roll size 1/20, means 260/20 = 13 roll-ups
Calculation of soft roofing for a multi-pitched roof
The area of the pack is 3.5 square meters.
We have 260 / 3,5 = 74,5 packs. Overlaps, joints must overlap. For them, the stock is 80 packs.
Other important details:
- Ridge board
- Internal corners, endowment
For the roof ridge, we take 80 running meters, for the inner corner - 50 meters.
