Finding Square Footage Of A Roof

Then add 10 to the number to account for waste.

Finding square footage of a roof. 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. 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. How to calculate the roof area using the building square footage the pitch of the 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.

The total amount of roofing material you need is 17 300 1 730 19 030 square feet. So you re thinking of reroofing the house yourself and want an estimate for how much roofing material you. Use our roof pitch calculator to find the pitch of your roof. Multiply the square footage of your roof by 1 to get the 10 percent waste allowance.

Steep roofs measure your house at ground level then add in the roof s overhang for greater accuracy. 1square of roofing covers 100 square feet of roof a bundle is 1 3 of a square. Use this information if. Next find the square footage of the metal roofing panels you want to use.

To conclude the example if your total roofing area is 17 300 square feet your waste allowance would be 17 300 x 1 1 730 square feet. Calculate square footage for a roof by measuring and by performing some basic math equations. With the area measurement you can learn the approximate cost of a new roof. 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.

Measure the length and width in feet then multiply together to find the square footage. Since it takes 3 bundles of shingles to cover a square plan to purchase 3 bundles for each square.
