This free online truss and roof calculator generates the axial forces and reactions of completely customisable 2d truss structures.
Roof truss angle finder.
Simply set it on your roof or the underside of a rafter and read the gauge.
Recalculate this value into an angle.
Finally you can find the roof pitch in the form of x 12.
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.

Most angle finders only work on the top side of a roof.
The truss calculator will determine your roof trusses based on key inputs related to the pitch span and overhang of your roof.
