How Do You Measure Square Feet Of A Roof

Once you work through the basic triangle we will review a typical roof and how to apply some simple math to calculate how much material you will need for a roof used in our hypothetical example.

How do you measure square feet of a roof.

This yields a product called the area which is expressed in square feet or square inches if you are calculating a much smaller space such as a dollhouse. As an example if your overhang is 12 inches you ll add 2 feet to the overall length and 2 feet to the overall width of the house. 1 roof square 100 square feet. Make a sketch of your roof before you go out to measure it.

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 you are replacing your entire roof you will need to purchase shingles in 50 squares to sufficiently cover your 5 000 square foot roof. A home s roof is measured in squares. If your roof is 5 000 square feet you will have 50 squares.

Before you do any roofing work you must calculate the roof s square footage to determine how much material you need. Measure and mark the square footage of each triangular section carefully as these tend to differ in size. Measure your house at ground level then add in the roof s overhang for greater accuracy. If you have a roof section that s 30 feet 9 1 m long and 12 feet 3 7 m high multiplying those dimensions would give you an area of 180 square feet 17 m 2.

Shingles and other roofing materials such as underlayment are typically measured in squares that are 10 feet long and 10 feet wide with each square measuring 100 square feet. For example if you are buying carpet for a room that is 12 feet long and 10 feet wide. The length l times the height h of a triangle is twice its area a2. Our patented technology calculates square footage and linear measurements for the roof siding windows trim and more.

Each square is 100 square feet. Things you will need steel tape measure. Roof pitches in. Just snap a few photos of the exterior of the house with the hover app and our patented technology will take it from there.
