12 Degree Roof Pitch Options

The picture below shows the pitch of a 7 12 roof slope meaning that for 12 of horizontal measurement roof run the vertical measurement roof rise is 7.

12 degree roof pitch options.

This means if a roof rises 4 in the length of 12 your roof pitch would be 4 12 or 18 43 degrees. 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. Find the inverse tangent of the pitch to find the angle in degrees. Pitch is the term used to describe the angle slope or slant of your roof.

There are some standing seam metal roofing options available from atas and other manufacturers that can be installed on a roof with pitch of 1 12. 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. Most roof s have a pitch in the 4 12 to 9 12 range. You could also opt for a pvc flat roofing membrane.

Roof pitch designations are comprised of two numbers indicating a ratio. However if you to do the process using your own knowledge you can still convert pitch to degrees by dividing the rise and run and get its corresponding measurement. 4 12 is quite typical. So you would need to pick the right option as most regular standing seam metal roofs will require a roof pitch of 2 12 or even 3 12 at a minimum.

This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement. The table below shows common roof pitches and the equivalent grade degrees and radians for each. What degree angle is a 12 12 pitch roof. With the use of this converter it will be easier for you to locate a 30 degree roof pitch 20 degree roof pitch 25 degree roof pitch or a 15 degree roof pitch.

The following table shows the roof pitch rise in run equivalents for all roof slopes in degrees from 1 to 72. Roof pitch defined and explained. If you want to discuss other low roof pitch options you can contact a local professional roofer. Or the colon can replace the slash as in 2 12 or 7 12.

Divide the first part of the ratio by 12 to work out the pitch. 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 ratio can be indicated by a division slash separating the numbers such as 2 12 or 7 12. Anything under 3 12 is a low pitch roof.

A 12 12 pitch roof has a pitch angle of 45.
