The Roof Pitch Calculator is an essential tool for construction professionals, architects, and contractors who need to determine accurate roof measurements and specifications. This comprehensive calculator enables users to quickly compute various roof measurements, including pitch ratio, angle degrees, rise, run, and slope percentage, all from basic input parameters. Whether you’re planning a new construction project, estimating materials, or preparing detailed specifications, this tool streamlines the calculation process and ensures precise results. Construction professionals can save valuable time by avoiding manual calculations while maintaining accuracy in their project planning. For maximum efficiency in your roofing projects, utilize this calculator to generate instant, reliable measurements that can be immediately applied to your construction specifications.
Enter any two of rise, run, angle, or pitch ratio and the tool instantly returns the other values plus slope %. A 9 ft rise and 15 ft run gives a 31.0° pitch and 60 % slope—well above the 4:12 minimum for asphalt shingles (ICC R905.2.2-2021).
