  • received and the number of rows of sheets in a row is multiplied to obtain the number of sheets of slate on one skate. If the roof gable, the result is double.

For hipped roofs rays geometrically calculated area (the area of ​​triangle and the area of ​​a trapezoid, as shown in the figure), divided by the area of ​​a sheet of slate, and add 15%.

The order of stacking the following: first, the lower leaf 3-4, then 2-3 over them the second row of the second row - 1-2 third-row cloth, then each row, starting from the bottom, add one canvas;
  • Slate wave overlaps should be at the prevailing direction of the wind, the wind is not blowing under the slate and did not try to lift it.
