For the correct determination of the structure andthe amount of material required, using special software. Calculation of the mansard roof truss system - is the key to proper and accurate selection of materials and to determine the size of the roof.

The types of attic floors:

  • triangular or regular. The most familiar to us top of a private house. Rafter system gable mansard roof is the simplest to implement and requires the least amount of material. However, this option gives the least amount of space;

  • width and length of the basics - the size of your home;
  • precipitation (snow and rain). It is necessary to know in order to clearly define the angle of the ramp;
  • width of the junction overlap parts.
Important! If you specify overlapping coats, do not try to save money, as this will allow you to protect the interior from rain.

Example of calculating the height of the gable roof. By assumption, the house has a length of 12 meters and a width of 3. The precipitation allows you to choose an angle of 40 degrees. The calculation is carried out according to the formula - Hk = L * tgA

As seen in Figure Hk - the required height, L - semi-detached house width. TGA - tangent of the angle selected.

Thus we get the following:

Hk = 3/2 * 0.84 = 1.26

The height of the proposed roof would 1,26metra. Be careful during all measurements, it will serve as a starting point for your calculations.

Once payment is made mansard roof truss system and purchased all the materials, the next stage - the preparation.

Removing the old design and preparation of the roof ↑
