The rise is the vertical length from the top of a stud wall to the peak of the roof. 8 inches and you have an 8 in 12 pitch. This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement.

Slope a roof s slope is the number of inches it rises for every 12 inches of horizontal run a roof with a 4 in 12 slope rises 4 inches for every 12 inches of horizontal run. Then calculate the pitch of the roof by placing a level against it angling the level so the bubble is centered and measuring the distance between the end of the level and the roof. On a ladder beside the roof place the level a foot or so up the roof hold it level and measure from the 12 inch mark on the level s bottom straight down to the roof. Roof pitch refers to the measurement of the slope of a roof and you express this as a ratio.

A measurement of roof area that equals 100 square feet an area 10 feet by 10 feet. If this distance measures 4 inches you have a 4 in 12 pitch. Although there s isn t any standard pitch of a roof used on all kinds of sloped roofs you can determine the range of pitches by using a roof angle calculator and by considering factors like the local climate and roofing materials.

A 4 in 12 roof pitch means the roof rises 4 inches for every 12 inches it runs. If this isn t practical then perform the same measurement on the underside of the roof. Roof reports and wall reports made easy. A roof s pitch is the rise for every 12 inches it runs.

Measure an outside wall from end to end where the gable roof comes to a peak above the wall.
