Roof pitch refers to the slope which the rafter creates. You can assess this in two ways either as the roof pitch angles which the rafters make with the horizontal or the proportion between the run and the rise of the roof.

Find the inverse tangent of the pitch to find the angle in degrees. Check your results with the omni roof pitch calculator. A 12 12 pitch roof has a pitch angle of 45. In the united states a run of 12 inches 1 foot is used and pitch is measured as the rise of the roof over 12 inches.
