Simply set it on your roof or the underside of a rafter and read the gauge.
Roof truss angle finder.
Use the diagrams on this page as a reference when inputting rise and run and while interpreting the calculated results.
No fooling around with tape measures and levels.
The roof pitch calculator calculates slope pitch angle and rafter lengths based on input of rise m and run r.
The truss calculator will determine your roof trusses based on key inputs related to the pitch span and overhang of your roof.
Recalculate this value into an angle.
