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.
12 12 roof pitch in degrees.
So these are the two ways in you find roof pitch degree for your roof.
Image 1 12 to 12 12 roof pitch 7 12 pitch.
Roof pitch degree table.
The table below shows common roof pitches and the equivalent grade degrees and radians for each.
The following are important details to better understand this conversion.
Also roof pitch angle is sometimes referred to as 12 12 6 12 8 12 and so forth.
There are many websites which are offering this facility.
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.
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.
