Roof Peak Measurement

If this distance measures 4 inches you have a 4 in 12 pitch.

Roof peak measurement.

Divide the measurement in half and mark the center of the wall at head height below the peak. If this isn t practical then perform the same measurement on the underside of the roof. A roof s pitch is the rise for every 12 inches it runs. 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.

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. This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement. We included a roof pitch chart below the 7 12 example image and the calculator below that.

We ll use satellite imagery and trigonometry to calculate your roof s measurements. 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. Roof reports and wall reports made easy. A 4 in 12 roof pitch means the roof rises 4 inches for every 12 inches it runs.

If you re putting down new roofing materials on your home or another building with a hip roof your first step will be to find the exact dimensions of each of the roof s individual faces then use those measurements to calculate its total area in square feet. Measure an outside wall from end to end where the gable roof comes to a peak above the wall. A measurement of roof area that equals 100 square feet an area 10 feet by 10 feet. To measure a roof start by measuring the length and width of the building s exterior walls and multiplying them to get the area.

Roof pitch refers to the measurement of the slope of a roof and you express this as a ratio. There are three different ways to find the pitch of a roof both from inside and outside of the home. A hip roof is a common roof style characterized by 2 pairs of opposing faces sloping downward from a high peak. 8 inches and you have an 8 in 12 pitch.
