Roof Pitch Degrees

The following diagram will let you easily convert roof pitch to degrees.

Roof pitch degrees.

A 7 12 pitch equals 30 26 degrees. 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. 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.

Look at the column labeled pitch then look under degrees to get the corresponding amount of degrees. But with the use of a roof pitch in degrees converter you will be able to get the correct measurement. Pitch is thus the ratio of the rise in inches to a 12 inch run and is often expressed using a semicolon for example 6 12. Roof pitch or slope is a measure of vertical rise to horizontal run expressed in inches per foot.

The 45 degree roofs seen on a frame houses are 12 in 12 but roofs can be even steeper consider the mansard roofs introduced by french second empire architects in the middle of the 1800s. Roof pitch varies depending on culture climate style and available materials. Often you express roof pitch as the ratio between the rise and the run in the form of x 12. 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.

In the uk the typical house has a pitch between 40 50 although 45 should be avoided. Roof pitch and corresponding angles. Pitched roofs begin with with slopes greater than 3 in 12. 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.

This means if a roof rises 4 in the length of 12 your roof pitch would be 4 12 or 18 43 degrees. Mansard roofs with nearly vertical faces can boast a pitch of 20 in 12. A a roof with a 6 rise for every 12 run has a 6 per foot or 6 in 12 pitch. There is no standard universal roof pitch.

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 following table shows the roof pitch rise in run equivalents for all roof slopes in degrees from 1 to 72. Roof pitch refers to the slope which the rafter creates.
