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.

How is a roof measured.

If you were to click on the peaks it wouldn t give you an accurate reading of your measurement. The length l times the height h of a triangle is twice its area a2. Roof pitch is measured by rise run rise the distance from the top of a stud wall to the peak of the roof. Roof reports and wall reports made easy.

Measuring your roof from the ground 1. The run always remains. We ll use satellite imagery and trigonometry to calculate your roof s measurements. Make sure to document the number of chimneys skylights or other obstructions and include dormers in your measurements.

With roofing software you can simply trace the footprint of such objects and subtract them from the total measurement. Find the length and width of the building s exterior walls. Multiply width x length this will give you the roof s square footage of one plane. To calculate the total square footage of the roof add up every plane s square footage.

For the latter measurements should ideally subtract the space taken up by those penetrations such as roof mounted ac units and skylights. Start by measuring the width and length of your roof including dormers. So if you divide your answer of a product of length times height by two you will get the area of a triangle. Climb to the peak of your roof.

L h 2 area calculating an area of a triangle when estimating a roof. It is often compared to slope but is not exactly the same. 1 roof square 100 square feet. Run the distance from the outside edge of a perimeter stud wall to the center of the house.

Bring a two foot level. This will make the basis of your material order significantly more accurate. Finally the more complex part measuring your roof s pitch. The pitch is the steepness of the roof.

Once you have this measurement you can then measure the footprint of the home and estimate the actual roof calculation based on the particular angle of the roof. Roof pitch roof pitch is the measurement of a roof s vertical rise divided by its horizontal run. Estimate or calculate the pitch of your roof low medium or high. First measure the length and width of each surface on the roof then multiply these values to get the square footage of that surface.

To find the pitch of your roof you ll first. Calculate the pitch of the roof.
