To calculate roof square footage, start by measuring the length and width of each roof plane, including any dormers or overhangs. For a simple gable roof, multiply the length by the width for each side, then add both totals together; complex roofs with hips or valleys require breaking down into triangles and rectangles. Pitch affects the area—use a pitch multiplier from online charts to adjust for slope. Finally, account for waste by adding 10-15% extra for cutting and overlaps.
