How Do You Measure A Roof To Get The Square Footage

1 roof square 100 square feet.

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

Then divide the total by 2 to get the square footage. Things you will need steel tape measure. For example if a triangle shaped roof plane measures 60 feet along the base and is 30 feet high we have 60 x 30 1 800 feet divided by 2 900 square feet for the triangle shaped plane. The length l times the height h of a triangle is twice its area a2.

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. Thus in a simple style house you ll only have to click on the corners. 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.

So if you divide your answer of a product of length times height by two you will get the area of a triangle. Calculate the square footage of a gambrel style roof using imperial measurements. Outside of the u s a degree angle is typically used. 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.

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. 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. For instance a 7 12 roof pitch means that the roof rises 7 inches for every 12 horizontal inches. Use the instructions for obtaining roof slope to add to your ground measurements.

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. 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. 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.
