20 Degrees Roof Pitch

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.

20 degrees roof pitch. Roof pitch refers to the measurement of the slope of a roof and you express this as a ratio. It is uncommon to find a roof below 15 but for those very low pitch applications there are interlocking clay pantiles available suitable for use down to 12 5. Although there s isn t any standard pitch of a roof used on all kinds of sloped roofs you can determine the range of. The table below shows common roof pitches and the equivalent grade degrees and radians for each.

Divide its rise by run in. 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. The following table shows the roof pitch rise in run equivalents for all roof slopes in degrees from 1 to 72. Locate its tangent or tan and follow the left row for you to read its corresponding degree.

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. Identify the rise and run. Pitch tan angle where angle is the roof pitch expressed in degrees. The value displayed as the rise will be your x.

Pitch tan angle use this when you express the angle of the roof pitch in degrees what is the standard pitch of a roof.
