The table below shows common roof pitches and the equivalent grade degrees and radians for each.
2 roof pitch in degrees.
To see what the degree equivalents are for standard rise in run roof pitches see our page quick reference.
The combination of two numbers are used to display or show the roof pitch.
The value displayed as the rise will be your x.
Set bevel gauge directly from phone or tablet screen.
The exact roof slope in degrees is given by the arctangent.
To use this method there are 3 possible places to take your measurements.
Two most common methods 4 12 or 4 12 are used for marking the pitch of a roof.
Enter base length to calculate rise and diagonal for current pitch angle.
How roof pitch manifests itself in various roof types.
The measurements are taken from the bottom of the rafters the procedure to calculate roof pitch is the same.
If you want to find the roof pitch in the form of x 12 simply calculate the pitch and substitute 12 for the run length.
Select inches to enter decimal inches or millimeters for metric.
This method tends to be more accurate because no layers of roofing are involved.
Definitions vary on when a roof is considered pitched.
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.
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.
Roof slope expressed as rise.
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.
Roof pitch angle in degrees.
12 pitch 45 degrees 11 pitch 42 5 degrees 10 pitch 40 degrees 9 pitch 37 degrees 8 pitch 33 75 degrees 7 pitch 30 5 degrees 6 pitch 26 5 degrees 5 pitch 22 5 degrees 4 pitch 18 5 degrees 3 pitch 14 degrees 2 pitch 9 5 degrees 1 pitch 4 5 degrees 0 pitch 0 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.
This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement.
The following table shows the roof pitch rise in run equivalents for all roof slopes in degrees from 1 to 72.
Visit this page on your phone to directly measure pitch and angles.
Identify the rise and run.
The rise will be equal to the amount of the incline within the given distance or the run that.
This means if a roof rises 4 in the length of 12 your roof pitch would be 4 12 or 18 43 degrees.

Determine its angle through taking a 12 inch level and.
Pitch tan angle where angle is the roof pitch expressed in degrees.
In degrees 10 2 in 12 or 1 in 6 is considered a minimum.
Roof angles and rafter plumb cuts.
