This page also explains how to convert one to another.

4 12 roof slope in degrees. Example with a 12 in 12 slope the wall or roof rises 12 inches in a 12 inch run a 12 in 12 slope 45 one could be inclined to assume that a 6 in 12 slope would equal half. The following table shows the roof pitch rise in run equivalents for all roof slopes in degrees from 1 to 72. The table below shows common roof pitches and the equivalent grade degrees and radians for each. 369 people used view all course.

Sometimes slope is referred to as pitch angle rise incline or grade. A 4 12 is a roof slope that rises by 4 inches for every 12 inches across. The table shows the equivalent ways of expressing the same roof pitch slope. This forms an angle of 18 5 between the horizontal section and the roof and creates a gentle incline that is seen as a midpoint between a low pitch and medium pitch roof.

Low slope roofing needs special techniques and materials in order to avoid leaks and roof damage and it ranges from 1 12 4 12. How to convert roof pitch in degrees converting this mathematical formula is not that easy especially if you don t have a lot of skill when it comes to math. A 4 12 is a roof slope that rises by 4 inches for every 12 inches across. 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.

Convert a roof pitch of rise in 12 to a roof angle in degrees. Degrees tan 1 43 calculated out this gives an angle of 23 27 degrees. Roof pitch slope roof angle degree 1 12 pitch 4 76 2 12 pitch 9 46 3 12 pitch 14 04 4 12 pitch 18 43 5 12 pitch 22 62 6 12 pitch 26 57 7 12 pitch 30 26 8 12 pitch 33 69 9 12 pitch 36 87 10 12 pitch 39 81 11 12 pitch. Low slope roofing in other texts refers to roofing systems for pitches below 4 in 12 of slope see low slope roofing and see.

Many different professions use slope in describing an angle. Low slope roofing is defined as any roof pitched at 3 in 12 or 14 degrees or 25 slope or less.
