The pitch is the steepness of the roof. Roof pitch roof pitch is the measurement of a roof s vertical rise divided by its horizontal run. So if you divide your answer of a product of length times height by two you will get the area of a triangle. The length l times the height h of a triangle is twice its area a2.
