Terms
Last updated August 23, 2026.
Using the tools
You may use PitchCalc for lawful personal and commercial planning. Do not interfere with the site or attempt to misuse it.
Planning estimates only
Results are planning estimates from the formulas on the methodology page. They are not a contractor bid, a structural design, a building-code review, or a final material order. Complex roofs with hips, valleys, and dormers should be measured plane by plane. Review important numbers before you order materials or hire work.
Availability
Tools may change, move, or be withdrawn. PitchCalc may update these terms as the site and any future advertising model develop.
