How Is A Roof Measured

Start by measuring the width and length of your roof including dormers.

How is a roof measured.

Multiply width x length this will give you the roof s square footage of one plane. L h 2 area calculating an area of a triangle when estimating a roof. With roofing software you can simply trace the footprint of such objects and subtract them from the total measurement. Stretch your tape measure along the walls from end to end.

Bring a two foot level. Use a pitch. This will make the basis of your material order significantly more accurate. The length l times the height h of a triangle is twice its area a2.

Run the distance from the outside edge of a perimeter stud wall to the center of the house. For the latter measurements should ideally subtract the space taken up by those penetrations such as roof mounted ac units and skylights. 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. 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 is measured by rise run rise the distance from the top of a stud wall to the peak of the roof. 1 roof square 100 square feet. To find the pitch of your roof you ll first. We ll use satellite imagery and trigonometry to calculate your roof s measurements.

Thus in a simple style house you ll only have to click on the corners. The run always remains. Finally the more complex part measuring your roof s pitch. Estimate or calculate the pitch of your roof low medium or high.

To calculate the total square footage of the roof add up every plane s square footage. Measuring your roof from the ground 1. The pitch is the steepness of the roof. Roof reports and wall reports made easy.

Climb to the peak of your roof. First measure the length and width of each surface on the roof then multiply these values to get the square footage of that surface. Roof pitch roof pitch is the measurement of a roof s vertical rise divided by its horizontal run. Calculate the pitch of the roof.

Find the length and width of the building s exterior walls. So if you divide your answer of a product of length times height by two you will get the area of a triangle.
