You can find the roof pitch in the form of x 12 like 4 12 or 9 12.
Roof slope conversion tables.
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.
To obtain an accurate roof pitch measurement properly measure the rise and run.

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.
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.

We included a roof pitch chart below the 7 12 example image and the calculator below that.
Two most common methods 4 12 or 4 12 are used for marking the pitch of a roof.
Although there s isn t any standard pitch of a roof used on all kinds of sloped roofs you can determine the range of pitches by using a roof angle calculator and by considering factors like the local climate and roofing materials.
Roof pitch conversion charts are very useful for one thing they give you all the information that you need to provide to the professionals.
Example slope as grade.
To see what the degree equivalents are for standard rise in run roof pitches see our page quick reference.
The following table shows the roof pitch rise in run equivalents for all roof slopes in degrees from 1 to 72.
If this isn t practical then perform the same measurement on the underside of the roof.
