Calculating a roof pitch

Question

We have been asked to upgrade a community hall that was built in 1935

It needs new scissor trusses to replace the old sagging rafters. How do I calculate the pitch?.

The drawing is to scale at 1/4" - ft

Thanks

Murray

If you are looking for the area of the roof, you can also use the Pitch / Degree / Grade function which can be found in the Measurements panel.  If you are just looking for the pitch of the roof and you have a section through the building, then you Angle tool which is Shift + Alt + G.
