Measure roof pitch from ground.

Express roof pitch as the ratio of the amount of the vertical rise of a roof or rise over the corresponding horizontal distance or run you write the pitch assuming a run of 12 inches thus the ratio would describe how much a roof rises for each foot of the run. For instance a 7 12 roof pitch means that the roof rises 7 inches for every 12 horizontal inches. To find the pitch of your roof you ll first. In the united states a run of 12 inches 1 foot is used and pitch is measured as the rise of the roof over 12 inches.

See the image below for more explanation on rise run and pitch. To sum it up each individual tab on a 3 tab shingle measures approximately 12 wide by 6 high. If you do need to calculate the pitch an estimate or shortcut is usually more practical than measuring the roof s overall dimensions. Calculate the pitch of the roof.

You ll need a level that is 12 or longer and a tape measure. A roof s pitch is determined by how much it rises vertically for every foot it runs horizontally. A 12 in 12 pitch is a steep 45 degree angle roof. Use a pitch.
