Pitch tan angle where angle is the roof pitch expressed in degrees.

2 12 roof pitch angle. Resilient asphalt shingles lie much flatter to the substrate than slate tile and concrete which keeps water from being easily blown under them. Two most common methods 4 12 or 4 12 are used for marking the pitch of a roof. The ratio can be indicated by a division slash separating the numbers such as 2 12 or 7 12.
