Finding The Square Footage Of A Roof

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.

Finding the square footage of a roof. How to calculate the roof area using the building square footage the pitch of the roof. Just multiply the length and width dimensions. Multiply the square footage of your roof by 1 to get the 10 percent waste allowance. 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.

Calculate square feet meters yards and acres for flooring carpet or tiling projects. 1square of roofing covers 100 square feet of roof a bundle is 1 3 of a square. Calculate square footage square meters square yardage and acres for home or construction project. 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.

How to calculate square footage for rectangular round and bordered areas. Calculate square footage for a roof by measuring and by performing some basic math equations. 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. The total amount of roofing material you need is 17 300 1 730 19 030 square feet.

With the area measurement you can learn the approximate cost of a new roof. Then add 10 to the number to account for waste. Calculate project cost based on price per square foot square yard or square meter. Use this information if.

Steep roofs measure your house at ground level then add in the roof s overhang for greater accuracy. 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. If a section is 120 feet 37 m x 100 feet 30 m its total square footage would be 12 000 square feet 1 100 m 2.

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. So you re thinking of reroofing the house yourself and want an estimate for how much roofing material you. Enter measurements in us or metric units.
