## Help

The program is designed to calculate the single-pitch roof materials: the amount of sheet material (Onduline, Nulin, slate or metal tiles), underlay material (asphalt, roofing), number of boards lathing and rafters.

Attention! Please note that the program considers the sheeting on the basis of area of the roof.
For example, the 2.9 series, multiply by 7.6 sheets in a row. In a real construction put 3 rows.
To refine the calculation to reduce the height of the sheet to get around a number of series.

Later will be a separate program for more predictive calculation of roofing material.

And do not forget to buy construction materials from the reserve.
