Standard roof pitch degrees.

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. Pitches lower than 4 12 have a slight angle and they are defined as low slope roofs. A pitch over 9 12 is considered a steep slope roof between 2 12 and 4 12 is considered a low slope roof and less than 2 12 is considered a flat roof. You write the pitch assuming a run of 12 inches thus the ratio would describe how much a roof rises for each foot of the run.
