How Do You Measure Square Feet Of A Roof

The length l times the height h of a triangle is twice its area a2.

How do you measure square feet of a roof.

Our patented technology calculates square footage and linear measurements for the roof siding windows trim and more. Things you will need steel tape measure. Just snap a few photos of the exterior of the house with the hover app and our patented technology will take it from there. Each square is 100 square feet.

Measure and mark the square footage of each triangular section carefully as these tend to differ in size. A home s roof is measured in squares. Roof pitches in. 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.

Once the digital property is complete you will receive detailed exterior measurements and an interactive 3d model to help homeowners design their projects. To find square feet multiply the length measurement in feet by the width measurement in feet. Before you do any roofing work you must calculate the roof s square footage to determine how much material you need. 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.

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. This nominal square footage amount is then multiplied by a factor associated with the roof s pitch. For example if you are buying carpet for a room that is 12 feet long and 10 feet wide. 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.

If your roof is 5 000 square feet you will have 50 squares. Make a sketch of your roof before you go out to measure it. 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. 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.
