The roof pitch is the angle of the roof and can be measured in several ways, but is most commonly expressed in rise over a standard 12-inch run. But, in order to calculate the rafter length, we need to calculate the pitch in degrees. The angle in degrees is equal to the inverse tangent of the pitch of the roof.
