Roof Pitch 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.

Roof pitch degrees.

Roof pitch to degrees equivalents this drawing demonstrates how many degrees rise for each pitch of a typical roof. 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. 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.

Divide its rise by run in. 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. There is no standard universal roof pitch. The following table shows the roof pitch rise in run equivalents for all roof slopes in degrees from 1 to 72.

Pitch angle incline slope they all can be used to refer to the steepness of a roof. Roof pitch refers to the slope which the rafter creates. Often you express roof pitch as the ratio between the rise and the run in the form of x 12. Roof pitch varies depending on culture climate style and available materials.

Rise run rise run slope. Active ventilation products. Skip to main content. 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.

Identify the rise and run. In the usa the range of standard pitches is anywhere between 4 12 and 9 12. 8 12 pitch 33 75 degrees. How to convert roof pitch to degrees.

To do this simply convert the rise and run as a fraction to a decimal form eg. First convert the pitch to a slope. To see what the degree equivalents are for standard rise in run roof pitches see our page quick reference. The rise will be equal to the amount of the incline within the given distance or the run that.

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. This means if a roof rises 4 in the length of 12 your roof pitch would be 4 12 or 18 43 degrees. Look at the column labeled pitch then look under degrees to get the corresponding amount of degrees. In the uk the typical house has a pitch between 40 50 although 45 should be avoided.

Determine its angle through taking a 12 inch level and. Roof pitch and corresponding angles.
