Hassan Nawaz, Publisher.

Hassan Nawaz is an engineer (B.Sc. Electrical Engineering) who builds and publishes RoofPitchMath. He is not a roofer. The figures come from roof geometry and the minimum slopes in the International Residential Code, and each page names its sources. Every calculator is tested against worked examples before it goes live.

What I write here

I write and test every calculator on RoofPitchMath, check each formula against the published standard or reference table it comes from, and update pages when those standards change.
