Roof Calculator – Pitch

Roof Calculator is a clear, fast tool for working out roof pitch and materials. Built from the ground up for metric units and local building practice, with the correct terms throughout – not a rushed machine translation. Enter the roof rise and span, and instantly see: - Pitch in degrees, percent and ratio (e.g. 1:2.5) - Slope length - A clear cross-section drawing of your roof The app also warns you if the pitch is too shallow for the chosen roofing material – felt, standing seam, profiled metal, tile or slate. A pitch that is too shallow can cause leaks or block the building permit, saving you from costly mistakes.
