For DIY Builders
Skip the Math
Built-in scales for common pitches mean you don't need a calculator on the roof.
If You're Building Your First Roof
The Rapid Rafter has the unit-run scales for both common (12) and hip/valley (17) rafters stamped right on the body. You don't need to memorize the math — the angles you need are already there.
Common DIY Projects
- Shed roofs (single-pitch)
- Gable additions
- Pergolas with sloped roofs
- Tree houses + play structures
- Stair stringers
- Picnic tables + outdoor furniture (square cuts)
Free Calculators to Pair With It
We built a free roof pitch calculator and rafter calculator so you can plan before you cut. Both work on phones at the lumber yard.
