Roofing & Framing Calculators
Roof pitch, shingles, stairs and deck boards for exterior projects.
Roofing and framing estimates start with slope and span. These calculators convert rise and run into pitch, roof area, shingles, stair stringers and deck boards, so the material order matches the geometry instead of a rough guess.
