A 12 12 pitch roof has a pitch angle of 45. Some roof specifications may express slope in the typical geometric terms of degrees.

A pitch of 2 12 is the minimum pitch for shingles made of asphalt so your roof just barely makes the cut off for one of the most popular roofing material options. Resilient asphalt shingles lie much flatter to the substrate than slate tile and concrete which keeps water from being easily blown under them. 2 12 roof pitch angle 9 46 degrees.
