## What is RoofPitch?

Turn rise and run into pitch, angle and rafter length, on the roof, without the trig.

RoofPitch is a fast, no-nonsense roof calculator for framers, roofers, and anyone re-roofing their
own house. Enter a slope any way you have it, and read back every other form of it right away.

WHAT IT DOES
- Pitch from rise and run, in the same unit, either measurement system.
- Every form of the slope at once: x-in-12 pitch, angle in degrees, and percent grade.
- Common rafter length from your span and pitch, with ridge shortening and the overhang tail worked in.
- Hip and valley rafter lengths, using the correct 45 degree plan diagonal, plus the hip angle.
- Roof area, roofing squares, and the shingle bundles to order, with your own waste allowance.
- A live cross-section that gets steeper as the pitch does, so the picture always matches the numbers.
- Metric or imperial throughout: feet and inches, or metres and centimetres.

SAVE EVERY ROOF
Save each roof you measure to your Jobs library. Reopen it any time, edit the sizes, and see a chart
across every roof you have on file. Nothing leaves your iPhone.

FREE AND PRO
Pitch and angle are free, forever. The one-time Pro unlock adds rafter lengths, roof area and the
material estimate, and lets you export. There is no subscription: pay once and keep it.

PRO EXPORT
Export a per-roof PDF cut sheet with the pitch, rafters, area and materials, and a CSV of your whole
library, straight from the share sheet.

PRIVATE BY DESIGN
No account, no cloud, no tracking. Every roof you enter stays on your device.

RoofPitch is a calculator and estimating aid. Check local codes and material coverage before you cut
or order.
