RoofPitchCalc.com is a dedicated construction utility designed to bridge the gap between architectural blueprints and job-site reality. We know that in roofing and framing, a “close enough” calculation can lead to wasted lumber, uneven eaves, and costly material returns.
We built this tool to be the ultimate digital carpenter’s assistant. Unlike basic calculators that only give you a ratio, our engine handles the complex trigonometry of Total Rafter Lengths (including tails), Hip & Valley diagonals, and Material Estimation for shingles and metal roofing. Whether you are a professional roofer bidding on a 4,000 sq ft home or a DIYer building a backyard shed, we provide the precise geometry you need to cut with confidence.
