This means if a roof rises 4 in the length of 12 your roof pitch would be 4 12 or 18 43 degrees.
12 12 roof pitch in degrees.
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 following are important details to better understand this conversion.
So these are the two ways in you find roof pitch degree for your roof.
But how are going to determine the angle s degree.
Roof pitch degree table.
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.
There are many websites which are offering this facility.
The table below shows common roof pitches and the equivalent grade degrees and radians for each.

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