Measure roof slope with the Roof Slope Assistant

Section 3 of the Wind Mitigation form asks whether the roof slope is at least 6:12. The Roof Slope Assistant (beta) uses your phone's camera and motion sensors to help you decide and document it.

Use it from the ground

1. In section 3, choose Assist Me next to "Need help with the slope?"
2. Stand far enough back to see a gable end or rake edge clearly, and keep it square in the frame.
3. Tap the amber guide line to start Level Assist.
4. Tilt your phone until the guide line matches the roof edge.
5. Tap inside the center circle, or choose Capture Frame, to freeze the view.
6. Tap the guide again to lock the reference.
7. Choose Send to Report to attach the evidence image.

The guide marks the 6:12 threshold, a 26.57° angle.

Choose the answer

• If the roof edge looks steeper than the guide line, choose Greater than or equal to (≥ 6:12).
• If it looks flatter, choose Less than (< 6:12).

Then choose Apply to Form.

Use your judgment

The assistant is a visual aid. Camera angle, lens distortion and roofs with several slopes can all affect the result. Confirm slope by your usual method when it's close to the threshold.
