Mounting of metal tile

When calculating a roof length of a leaf is selected to the equal length of a slope of a roof (the metal tile is made the necessary sizes). At installation of a metal tile the leaf is mounted so that the sheet edge acted on 40 mm from eaves in order that on the fad there was a space for ventilation. Calculations are made according to the drawing, but after all measure the prepared design of an obreshetka. Also carry out measurements of a roof on the diagonal that it will be convinced that it is rectangular.

The number of sheets easily pays off on a formula: length of eaves is divided into the useful width of one leaf.

Each slope pays off individually.
