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.
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.
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.
Anything above 6 12 is a steep roof pitch since it becomes harder to walk on the roof.
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.
To convert between american roofing ratios and pitch degrees follow these steps.
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.
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.
Anything under 3 12 is a low pitch roof.
What degree angle is a 12 12 pitch roof.
The ratio can be indicated by a division slash separating the numbers such as 2 12 or 7 12.
Divide the first part of the ratio by 12 to work out the pitch.
Find the inverse tangent of the pitch to find the angle in degrees.
4 12 is quite typical.
Most roof s have a pitch in the 4 12 to 9 12 range.
Roof pitch defined and explained.
The table below shows common roof pitches and the equivalent grade degrees and radians for each.
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.
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.
A 3 12 roof pitch angle is about 14 so on and so forth.
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.
This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement.
This means if a roof rises 4 in the length of 12 your roof pitch would be 4 12 or 18 43 degrees.
