Roof Pitch Degrees

To see what the degree equivalents are for standard rise in run roof pitches see our page quick reference.

Roof pitch degrees.

In the uk the typical house has a pitch between 40 50 although 45 should be avoided. The following table shows the roof pitch rise in run equivalents for all roof slopes in degrees from 1 to 72. Roof pitch to degrees equivalents this drawing demonstrates how many degrees rise for each pitch of a typical roof. This means if a roof rises 4 in the length of 12 your roof pitch would be 4 12 or 18 43 degrees.

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. Divide its rise by run in. 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. 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.

Rise run rise run slope. Identify the rise and run. Often you express roof pitch as the ratio between the rise and the run in the form of x 12. Active ventilation products.

This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement. 8 12 pitch 33 75 degrees. Determine its angle through taking a 12 inch level and. Locate its tangent or tan and follow the left row for you to read its corresponding degree.

Roof pitch and corresponding angles. 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. To do this simply convert the rise and run as a fraction to a decimal form eg. Look at the column labeled pitch then look under degrees to get the corresponding amount of degrees.

Roof pitches ranging from 0 12 0 degrees to 21 12 60 26 degrees. 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. There is no standard universal roof pitch. Roof slope expressed as rise.

First convert the pitch to a slope. In the usa the range of standard pitches is anywhere between 4 12 and 9 12. Roof pitch refers to the slope which the rafter creates. Pitch angle incline slope they all can be used to refer to the steepness of a roof.

The rise will be equal to the amount of the incline within the given distance or the run that. Roof pitch varies depending on culture climate style and available materials.
