How Is A Roof Measured

Run the distance from the outside edge of a perimeter stud wall to the center of the house.

How is a roof measured.

Roof pitch roof pitch is the measurement of a roof s vertical rise divided by its horizontal run. L h 2 area calculating an area of a triangle when estimating a roof. Bring a two foot level. We ll use satellite imagery and trigonometry to calculate your roof s measurements.

Roof reports and wall reports made easy. Roof pitch is measured by rise run rise the distance from the top of a stud wall to the peak of the roof. Climb to the peak of your roof. This will make the basis of your material order significantly more accurate.

For the latter measurements should ideally subtract the space taken up by those penetrations such as roof mounted ac units and skylights. 1 roof square 100 square feet. Finally the more complex part measuring your roof s pitch. With roofing software you can simply trace the footprint of such objects and subtract them from the total measurement.

Thus in a simple style house you ll only have to click on the corners. To calculate the total square footage of the roof add up every plane s square footage. To find the pitch of your roof you ll first. Calculate the pitch of the roof.

The run always remains. Start by measuring the width and length of your roof including dormers. If you were to click on the peaks it wouldn t give you an accurate reading of your measurement. 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.

Measuring your roof from the ground 1. 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. Use a pitch. It is often compared to slope but is not exactly the same.

So if you divide your answer of a product of length times height by two you will get the area of a triangle. Make sure to document the number of chimneys skylights or other obstructions and include dormers in your measurements. The length l times the height h of a triangle is twice its area a2. Estimate or calculate the pitch of your roof low medium or high.

The pitch is the steepness of the roof. Multiply width x length this will give you the roof s square footage of one plane.
