1 12 Roof Pitch In Degrees

So these are the two ways in you find roof pitch degree for your roof.

1 12 roof pitch in degrees.

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. 1 12 pitch is equal to 5 degrees. The value displayed as the rise will be your x.

This means if a roof rises 4 in the length of 12 your roof pitch would be 4 12 or 18 43 degrees. Other than the 45 roof slope which is 12 in 12 none of the standard roof pitches 5 in 12 6 in 12 etc are equal to a whole degree. Steeper slopes increase the sail effect that makes them susceptible to 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. Therefore you need to make sure you have read through all the guidelines before attempting any work on the roof. If a roof rises 1 in a length of 12 this is 1 12 roof pitch. But with the use of a roof pitch in degrees converter you will be able to get the correct measurement.

Pitch tan angle where angle is the roof pitch expressed 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. Roof pitch angle roof pitch multiplier 1 12 4 76 1 0035 2 12 9 46 1 0138 3 12 14 04 1 0308 4 12 18 43 1 0541 5 12 22 62 1 0833 6 12 26 57 1 1180. A useful website that has a selection of conversion charts that can help with roofing can be found at the following address.

Roof pitch degree table. 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. The 30 degree 7 12 roof recommendation is backed up by testing according to the publication science daily. The following table shows the roof pitch rise in run equivalents for all roof slopes in degrees from 1 to 72.
