Roof Square Footage Estimator

Now assuming an average pitch of 9 12 we multiply the 2d area of 1 300 by 1 25.

Roof square footage estimator.

Then add the two planes together to derive the total square footage of the 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. You will need to express this size in terms of square feet. To find the squares divide the overall roof area by 100 and then round up.

Steep roofs measure your house at ground level then add in the roof s overhang for greater accuracy. 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. 120 x 100 12 000 sq. The calculator cannot account for complex shapes based on a measurement of square footage alone.

1square of roofing covers 100 square feet of roof a bundle is 1 3 of a square. Assuming this is a hip roof we multiply this by 1 1 which gives us roughly 18 squares or 1 800 square feet of the roof surface. 120 x 100 12 000 sq. You can use the roofing calculator below to get a rough estimate of roofing costs per square foot depending on the type of roofing material.

It will display 3 figures. For instance if the roof is 1550 square feet then it is 16 squares. For the total square footage of the roof.
