The following table shows the roof pitch rise in run equivalents for all roof slopes in degrees from 1 to 72.
Roof pitch degrees.
To find the angle of a roof in degrees convert the pitch to a slope then convert to degrees by finding the arc tangent of the slope.
Locate its tangent or tan and follow the left row for you to read its corresponding degree.
There is no standard universal roof pitch.
To see what the degree equivalents are for standard rise in run roof pitches see our page quick reference.

How to convert roof pitch to degrees.
This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement.
In the roofing trade the go to term is pitch and it is expressed in terms of 12 inches so the pitch of a roof is determined by how many inches the slope rises for every 12 inches it runs horizontally.
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.
8 12 pitch 33 75 degrees.
Roof pitch to degrees equivalents this drawing demonstrates how many degrees rise for each pitch of a typical roof.
Roof pitch refers to the slope which the rafter creates.
Divide its rise by run in.
Identify the rise and run.
First convert the pitch to a slope.
Roof pitches ranging from 0 12 0 degrees to 21 12 60 26 degrees.
In the uk the typical house has a pitch between 40 50 although 45 should be avoided.
To do this simply convert the rise and run as a fraction to a decimal form eg.
In the usa the range of standard pitches is anywhere between 4 12 and 9 12.
Pitch angle incline slope they all can be used to refer to the steepness of a roof.
Look at the column labeled pitch then look under degrees to get the corresponding amount of degrees.
Roof pitch and corresponding angles.
Determine its angle through taking a 12 inch level and.
Active ventilation products.
This means if a roof rises 4 in the length of 12 your roof pitch would be 4 12 or 18 43 degrees.
Roof pitch varies depending on culture climate style and available materials.
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 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.
The rise will be equal to the amount of the incline within the given distance or the run that.
You can assess this in two ways either as the roof pitch angles which the rafters make with the horizontal or the proportion between the run and the rise of the roof.
