How to calculate roof pitch angles
Web1 feb. 2024 · • To begin, determine the length of your roof’s run-through tape measure or spirit level. The run is the distance between the apex of your roof and the wall on the horizontal plane. • The next step is to calculate the rise. The rise is the distance between your apex and the structure’s wall. WebBased on a few known measurements of your roof, the roof pitch calculator will give you all of the pitch-related information you need. ... Once you know the rise and run, equations for a right triangle can be used to determine the rafter length, roof angle, and grade. $$\text{Rafter length$^2$ = rise$^2$ + run$^2$}$$
