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.

In the usa the range of standard pitches is anywhere between 4 12 and 9 12. This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement. A 7 12 pitch equals 30 26 degrees. Roof pitch refers to the slope which the rafter creates.

Roof pitch to degrees equivalents this drawing demonstrates how many degrees rise for each pitch of a typical roof. Often you express roof pitch as the ratio between the rise and the run in the form of x 12. This means if a roof rises 4 in the length of 12 your roof pitch would be 4 12 or 18 43 degrees. 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.

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. 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. In the uk the typical house has a pitch between 40 50 although 45 should be avoided. The following diagram will let you easily convert roof pitch to degrees.

But with the use of a roof pitch in degrees converter you will be able to get the correct measurement. 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. Pitched roofs begin with with slopes greater than 3 in 12. 8 12 pitch 33 75 degrees. There is no standard universal roof pitch.

Roof pitch and corresponding angles. A a roof with a 6 rise for every 12 run has a 6 per foot or 6 in 12 pitch. Mansard roofs with nearly vertical faces can boast a pitch of 20 in 12.
