GablePitch

Roof pitch finder for iPhone.

Measure roof pitch in X/12, degrees, and percent: lay the phone on a rafter or deck, or stand in the yard and line up the gable in the camera. Pro adds a roof area, squares, and bundle estimator, saved jobs, and a one-page PDF job sheet. Pro is a one-time purchase.

Readings are estimates for planning. Phone sensors, cases, and viewing angle all affect accuracy. Always verify critical measurements on site.
