Additional material to account for waste and cuts
We calculate the actual roof area by applying a pitch factor to the base area. Then we add a waste factor to account for cuts and overlaps. Squares are rounded up to the nearest whole number (1 square = 100 sq ft). Bundles are calculated based on your selected bundles per square.
