Measure Roof Pitch From Ground

On the roof hold the level perfectly level and measure the height from the roof to the level 12 inches away from where the level touches the surface this will be the rise.

Measure roof pitch from ground.

Take the following steps to measure your roof from the ground. Find the length and width of the building s exterior walls. Go all the way around your house and fill in your outline with your measurements making sure to account for overhang. Calculate the pitch of the roof.

One method to find the pitch is to climb on the roof and measure the rise for a 12 run. Measuring your roof from the ground 1. Divide the slope by two to get the pitch. If you do need to calculate the pitch an estimate or shortcut is usually more practical than measuring the roof s overall dimensions.

Here are a couple examples. To find the pitch of your roof you ll first. Walking backwards and watching where you re going walk out to the distance where your eye aligns with the plane on the roof pitch. Outside of the u s a degree angle is typically used.

Thus a moderate 6 in 12 roof pitch means that the roof rises 6 inches vertically for every 12 horizontal inches it runs. 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. For a simple gable roof the span wall to wall will be twice the size of the run wall to ridge horizontally. Walk away from your house perpendicular to the wall that is under the roof pitch you d like to measure.

Use a pitch. For instance a 7 12 roof pitch means that the roof rises 7 inches for every 12 horizontal inches. You ll need a level that is 12 or longer and a tape measure. Use a simple formula to approximate the square footage of triangular areas where two sections of a roof meet at each.

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. Stretch your tape measure along the walls from end to end. To sum it up each individual tab on a 3 tab shingle measures approximately 12 wide by 6 high. Make a outline of your roof on paper.

Determine your roof pitch see roofpitch if you need help. Section off your roof and write your calculations down as shown below dotted lines. See the image below for more explanation on rise run and pitch. A 12 in 12 pitch is a steep 45 degree angle roof.

A roof s pitch is determined by how much it rises vertically for every foot it runs horizontally. The pitch is the steepness of the roof.
