How to find square footage of a roof.

Minor differences in calculations occur based on chimneys and other. 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. Steep roofs measure your house at ground level then add in the roof s overhang for greater accuracy. Since it takes 3 bundles of shingles to cover a square plan to purchase 3 bundles for each square.

Calculate square footage for a roof by measuring and by performing some basic math equations. Then add 10 to the number to account for waste. Keep in mind that the average size of a roof is 1 700 square feet so your total will likely be 10 higher or lower than this figure. Use this information if.

The calculator cannot account for complex shapes based on a measurement of square footage alone. The first step in a free roofing estimate is measuring the roof dimensions. With the area measurement you can learn the approximate cost of a new 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.

1square of roofing covers 100 square feet of roof a bundle is 1 3 of a square. On a multistory house use only the square footage of a single floor. In cases where a roof has a complex shape such as in the image to the right measuring the dimensions and areas of each part of the roof to calculate total area will result in a more accurate measurement of area. When calculating square footage for your roof always add at least 10 percent of the total to account for waste.
