How To Find Sq Footage Of Roof

Steep roofs measure your house at ground level then add in the roof s overhang for greater accuracy.

How to find sq footage of roof.

The answer is the number of roofing squares for the roof. Adding 1 gives us 1 1 9 10 9 then taking the square root gives us about 1 0541. 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. The calculator cannot account for complex shapes based on a measurement of square footage alone.

Multiply by the square footage of a single floor of your house. The lower slope length is measured from outside wall to the start of the upper sloped roof section. The top ridge will be shorter than the one of the gable roof but the four hips will add. The only difference in this calculation to the one for a gable roof area is the amount of the ridge.

Calculate the square footage area of a hip roof. 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. 1square of roofing covers 100 square feet of roof a bundle is 1 3 of a square. The total amount of roofing material you need is 17 300 1 730 19 030 square feet.

Multiply the square footage of your roof by 1 to get the 10 percent waste allowance. 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.
