Roof Pitch Degrees

The following table shows the roof pitch rise in run equivalents for all roof slopes in degrees from 1 to 72.

Roof pitch degrees.

There is no standard universal roof pitch. Roof pitch and corresponding angles. 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. 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.

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. With the use of this converter it will be easier for you to locate a 30 degree roof pitch 20 degree roof pitch 25 degree roof pitch or a 15 degree roof pitch. But with the use of a roof pitch in degrees converter you will be able to get the correct measurement. Roof pitch to degrees equivalents this drawing demonstrates how many degrees rise for each pitch of a typical roof.

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 diagram will let you easily convert roof pitch to degrees. A a roof with a 6 rise for every 12 run has a 6 per foot or 6 in 12 pitch. Often you express roof pitch as the ratio between the rise and the run in the form of x 12.

Mansard roofs with nearly vertical faces can boast a pitch of 20 in 12. This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement. 8 12 pitch 33 75 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. Roof pitch or slope is a measure of vertical rise to horizontal run expressed in inches per foot. 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.

Roof pitch varies depending on culture climate style and available materials. 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.
