Figuring Square Footage Of A Roof

1square of roofing covers 100 square feet of roof a bundle is 1 3 of a square.

Figuring square footage of a roof. Since it takes 3 bundles of shingles to cover a square plan to purchase 3 bundles for each square. So continuing our example if you ve got a two story house with a total square footage of 2 700 square feet with each floor having 1 350 square feet multiply 1 350 by 1 0541 to get 1 423 square. Get the square footage of roof and divide it by 100 and it will give the number of squares you need and for every decimal number over 3 buy a bundle to achieve the amount of material. When calculating square footage for your roof always add at least 10 percent of the total to account for waste.

To calculate the size of the roof you need to measure the size of the roof as if it were flat account for roof pitch calculate square footage and finally determine how many squares of material are required for the roof the calculator above can handle all of this simply enter the length width and pitch and it will determine the size of the roof in squares. The calculator cannot account for complex shapes based on a measurement of square footage alone. A square of shingles is the number of shingles needed to cover 100 sq feet of roof area. Use this information if.

Calculate the square footage area of a hip roof. To estimate roofing materials start by finding the total square footage of the roof and divide the number by 100 to determine the number of squares in the roof. Calculate square footage for a roof by measuring and by performing some basic math equations. As a rule of thumb there are 3 bundles to a square assuming that you are using three tab strip shingles.

The square footage of a hip roof area is identical to the square footage of a gable roof of the same size. With the area measurement you can learn the approximate cost of a new roof. 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. However shingles are packaged in a way that they are light enough for the average person to carry around.

The only difference in this calculation to the one for a gable roof area is the amount of the ridge. If your roof is flat or has no more than a 3 in 12 pitch you can calculate its total square footage by simply multiplying the length by the width.
