Great a complement to Dan’s square.

### 5/5 — The ultimate roofing square is amazing

*2021-10-06, version 1.0*

This app is a great accompaniment to the Ultimate Roofing Square. As a hobbyist self-builder it helped me cut a large double garage roof extension with ease over the summer (once I’d realised the hip rafters were a different pitch). This app is helpful, but I’d highly recommend the tool to go alongside it. Rob
