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