Image 1 12 to 12 12 roof pitch 7 12 pitch.
12 12 roof pitch in degrees.
The following table shows the roof pitch rise in run equivalents for all roof slopes in degrees from 1 to 72.
But how are going to determine the angle s degree.
Another option that is available for you in finding the pitch factor for your roof is to find roof pitch calculator online.
So these are the two ways in you find roof pitch degree for your roof.
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.
This means if a roof rises 4 in the length of 12 your roof pitch would be 4 12 or 18 43 degrees.
The following are important details to better understand this conversion.
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.
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.
