Figuring Sq Ft Of Roof

Because each 100 square feet of roof is one roofing square divide the total area from step 1 by 100.

Figuring sq ft of roof.

Convert the area to roofing squares. The answer is the number of roofing squares for the roof. A roof s pitch is determined by how much it rises vertically for every foot it runs horizontally. Enter square footage calculate or enter the square footage of the attic or area to be vented.

A square of shingles is the number of shingles needed to cover 100 sq feet of roof area. Shingles and other roofing materials such as underlayment are typically measured in squares that are 10 feet long and 10 feet wide with each square measuring 100 square feet. Thus a moderate 6 in 12 roof pitch means that the roof rises 6 inches vertically for every 12 horizontal inches it runs. Roofing contractors estimate projects and materials by the square so it is crucial to find this measurement to accurately estimate the amount of material needed.

The best part of a roofing calculator is that it offers a free insight into the total cost of the replacement roof project on a sq ft basis. However shingles are packaged in a way that they are light enough for the average person to carry around. A square simply refers to a 10 x 10 square of roofing. 1 acre 43 560 square foot 1 square yard 9 square foot 1 square meter 10 76 square foot 1 square inch 0 00064516 square foot calculating cost per square foot.

To find the squares divide the overall roof area by 100 and then round up. 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. This is simply 100 square feet of roof. The calculator cannot account for complex shapes based on a measurement of square footage alone.

When calculating square footage for your roof always add at least 10 percent of the total to account for waste. As you begin to calculate various costs you will see that the cost is a result of the interplay of many different variables including roof area in terms of footage measurement of any roof extras like. 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. As a rule of thumb there are 3 bundles to a square assuming that you are using three tab strip shingles.
