12 Degree Roof Pitch Options

Most roof s have a pitch in the 4 12 to 9 12 range.

12 degree roof pitch options.

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. What degree angle is a 12 12 pitch roof. Anything above 6 12 is a steep roof pitch since it becomes harder to walk on the roof. This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement.

If you want to discuss other low roof pitch options you can contact a local professional roofer. Divide the first part of the ratio by 12 to work out the pitch. Or the colon can replace the slash as in 2 12 or 7 12. 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.

Roof pitch defined and explained. The ratio can be indicated by a division slash separating the numbers such as 2 12 or 7 12. Find the inverse tangent of the pitch to find the angle in degrees. A 3 12 roof pitch angle is about 14 so on and so forth.

Roof pitch designations are comprised of two numbers indicating a ratio. Pitch is the term used to describe the angle slope or slant of your roof. 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. The table below shows common roof pitches and the equivalent grade degrees and radians for each.

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. 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 following table shows the roof pitch rise in run equivalents for all roof slopes in degrees from 1 to 72. 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.

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. You could also opt for a pvc flat roofing membrane. 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. 4 12 is quite typical.

Anything under 3 12 is a low pitch roof.
