Estimate Roof Square Feet

Roof pitches in degrees.

Estimate roof square feet. For estimating purposes we also assume that there is a chimney a couple of dormers and two layers of old shingles that need to be torn off and removed before a new roof. To find the squares divide the overall roof area by 100 and then round up. The average roof is 3 000 square feet or around 30 squares. Roofing material is estimated by the square which is equal to 100 square feet.

Your roof is without a doubt one of the most important elements of your home. 1square of roofing covers 100 square feet of roof a bundle is 1 3 of a square.

Estimate the pitch of the roof. This gives us a 3d roof area of 1 625 sq ft. 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. 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.

As an example if your overhang is 12 inches you ll add 2 feet to the overall length and 2 feet to the overall width of the house.

You will need to express this size in terms of square feet. 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. 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. Because each 100 square feet of roof is one roofing square divide the total area from step 1 by 100.
