For example, if you are conditionally divided into triangles roof, the calculation about this.Remember the Pythagorean theorem.In advance make a measurement of all necessary parameters using a tape measure.Draw a rough diagram.Let us assume that a party - it is the length of the slope of your roof in the projection.Party B - it is the height from the top of the slope of the roof to the lowest point.Party with - is the length of the roof (the real).Then calculate the ratio of the formula - c / a (this is your rate).Next, calculate the area of ​​ projection of the roof (you multiply the length by the width).Then multiply this figure by your ratio (c / a).Here's a rough area , because they will not take into account slopes and possible window.For the same formula you can approximately check the correctness of the calculation of the area of ​​the roof , if you ask for help from professionals.
