How Do You Measure A Roof To Get The Square Footage

If you use ground measurements to determine your roof squares you will need to also compensate roof overhang and slopes to get an accurate count.

How do you measure a roof to get the square footage.

So if you divide your answer of a product of length times height by two you will get the area of a triangle. Then divide the total by 2 to get the square footage. Use the instructions for obtaining roof slope to add to your ground measurements. If its pitch is 6 in 12 a pitch multiplier of 1 12 multiplying 1 152 sq ft 107 0 m 2 by 1 12 would give you an overall square footage of 1 290 square feet 120 m 2.

The lower slope length is measured from outside wall to the start of the upper sloped roof section. If you were to click on the peaks it wouldn t give you an accurate reading of your measurement. The roof surface area would be 24. 1 roof square 100 square feet.

For instance a 7 12 roof pitch means that the roof rises 7 inches for every 12 horizontal inches. How to calculate your roof square footage first measure the length and width of each surface on the roof then multiply these values to get the square footage of that surface. Multiply the number of roofing squares for a medium pitch roof by 1 12 to 1 25 or by 1 3 to 1 42 for a high pitch roof to get the square roof area. If your roof measures 48 feet 15 m x 24 feet 7 3 m multiplying its length by its width would give you a square footage of 1 152 square feet 107 0 m 2.

Outline the roof at the points that are on the same level or elevation to ensure that you re getting an accurate calculation of your roofing measurements. 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. Thus in a simple style house you ll only have to click on the corners. Outside of the u s a degree angle is typically used.

To convert the square footage to roof squares divide the square footage by 100. L h 2 area calculating an area of a triangle when estimating a roof. The length l times the height h of a triangle is twice its area a2. Things you will need steel tape measure.
