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.
14 12 roof pitch in degrees.
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.
Enter any pitch or fraction of pitch to find angle.
This means if a roof rises 4 in the length of 12 your roof pitch would be 4 12 or 18 43 degrees.
