A 12 12 pitch roof has a pitch angle of 45.

How to determine pitch of a pulley roof. The roof pitch is the slope of the rafter. The rise is the height of the roof and the run is the horizontal span as pictured above. Simply plug in the values of your roof and it will show you slope percentage degree and even length. Divide the first part of the ratio by 12 to work out the pitch.
