Convert roof rise and run into pitch per 12, slope percent, and roof angle in degrees. Use it for quick framing and roofing layout checks.
This calculator provides a geometry conversion, not architectural, structural, code, or safety advice. Do not use it alone to size framing, approve roofing materials, plan fall protection, or authorize construction. Follow current product instructions, approved plans, permits, and local building requirements. Consult a qualified roofing or design professional for structural work, complex roofs, leaks, or uncertain measurements, and avoid accessing a roof without proper training and protection.
