1 12 Roof Pitch In Degrees

If a roof rises 1 in a length of 12 this is 1 12 roof pitch.

1 12 roof pitch in degrees.

Image 1 12 to 12 12 roof pitch 7 12 pitch. The value displayed as the rise will be your x. The following table shows the roof pitch rise in run equivalents for all roof slopes in degrees from 1 to 72. This means if a roof rises 4 in the length of 12 your roof pitch would be 4 12 or 18 43 degrees.

Lower slopes don t handle wind driven rain as well. If you want to find the roof pitch in the form of x 12 simply calculate the pitch and substitute 12 for the run length. 1 12 roof pitch angle 4 76 degrees. A 30 degree roof slope 7 12 pitch is the right pitch to aerodynamically handle high wind.

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. The table below shows common roof pitches and the equivalent grade degrees and radians for each. Steeper slopes increase the sail effect that makes them susceptible to wind.
