Two most common methods 4 12 or 4 12 are used for marking the pitch of a roof. 45 this is our pitch calculator which will convert pitch to angle or angle to pitch for half degree roof slope calculations. Resilient asphalt shingles lie much flatter to the substrate than slate tile and concrete which keeps water from being easily blown under them.

Most roof s have a pitch in the 4 12 to 9 12 range. Roof pitch degree table. Pitch is the term used to describe the angle slope or slant of your roof. The ratio can be indicated by a division slash separating the numbers such as 2 12 or 7 12.

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.

On blue prints architects engineers usually display the pitch of a roof in the format shown on the image where number 4 represents a rise and number 12 represents a length.
