Divide its rise by run in.
2 roof pitch 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.
Determine its angle through taking a 12 inch level and.
The table below shows common roof pitches and the equivalent grade degrees and radians for each.
This method tends to be more accurate because no layers of roofing are involved.
Pitch tan angle where angle is the roof pitch expressed in degrees.
Roof slope expressed as rise.
To see what the degree equivalents are for standard rise in run roof pitches see our page quick reference.
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.
In degrees 10 2 in 12 or 1 in 6 is considered a minimum.
Enter base length to calculate rise and diagonal for current pitch angle.
Set bevel gauge directly from phone or tablet screen.
Locate its tangent or tan and follow the left row for you to read its corresponding degree.
Two most common methods 4 12 or 4 12 are used for marking the pitch of a 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.
This means if a roof rises 4 in the length of 12 your roof pitch would be 4 12 or 18 43 degrees.
Visit this page on your phone to directly measure pitch and angles.
The following table shows the roof pitch rise in run equivalents for all roof slopes in degrees from 1 to 72.
This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement.
The measurements are taken from the bottom of the rafters the procedure to calculate roof pitch is the same.
Directly measure roof pitch angle and calculate pitch and angle on phone or tablet.
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.
To use this method there are 3 possible places to take your measurements.
The combination of two numbers are used to display or show the roof pitch.
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.
Identify the rise and run.
Select inches to enter decimal inches or millimeters for metric.
The value displayed as the rise will be your x.
The underside of a barge rafter on a gable end.
The rise will be equal to the amount of the incline within the given distance or the run that.
Roof pitch angle in degrees.
How roof pitch manifests itself in various roof types.
The exact roof slope in degrees is given by the arctangent.
