The calculation mesh shingles 2

To simplify the calculations necessary to calculate the length of the ridge, valley, eaves, end of piece parts and other items. For calculations, we use the familiar hipped roof (Calculation mesh shingles Part 1), and for clarity, Figure 2.

8-Large wooden flooring;

9-curtain strap;

13-water drainage system.

Length of eaves (9,1) - the length of the horizontal lower edges slope.

Based on the example of the length of the eaves = 5.3 * 2 + 8.7 * 2 = 28 lm

The length of the skates (1) is the horizontal fractures stingrays.

Example: The length of skates = 4.5 + 4.2 * 4 = 21.30 lm

The roof contained in the example is a simplified version, which omitted some items that you can view details of the scheme 2.

All raw data for calculating the necessary amount of materials prepared by:

The actual area of the roof - 71.478 square meters

The total length of skates - 21.3 MP

The total length of eaves - 28 lm

The order of calculation:

1. Number of cellular shingles (ordinary shingles).

When calculating the number of rows of tile is compulsory registration compliance rate of the roof. For all types of roofs this figure is 1.05 (5%). On this basis the actual area of the roof must be multiplied by 1.05.

71.478 * 1.05 = 75.0519 square meters To calculate the number of packages received sum is divided by 3 (number of square meters of material in one package). 75.0519 / 3 = 25.0173 units - ie, In our case, an ordinary roof tiles to 25 packs of 3 sq. m. each.

2. Carpet underlay.

Carpet underlay is mounted on the valley (6), skates (1), eaves (9) and gables (7). If the roof pitch is less than 18 degrees, the carpet underlay is applied to the entire area of the roof. You should also take into account the overlap of rolls during installation (15cm). Thus, we obtain a universal formula - the actual area of the roof * 1.15 = 71.478 * 1.15 = 82.19 sq. m. Based on the fact that the carpet underlay is available in rolls of 15 square meters everyone gets - 82.19 / 15 = 5.47 rolls, ie, 6 pcs.
