Figure Out Sq Ft Of 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.

Figure out sq ft of roof.

As a rule of thumb there are 3 bundles to a square assuming that you are using three tab strip shingles. Convert the area to roofing squares. Let owens corning roofing help you calculate exactly how much ventilation you will need for a healthy and balanced attic with our 4 step ventilation calculator. 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.

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 total amount of roofing material you need is 17 300 1 730 19 030 square feet. The calculator cannot account for complex shapes based on a measurement of square footage alone. Thus a moderate 6 in 12 roof pitch means that the roof rises 6 inches vertically for every 12 horizontal inches it runs.

The answer is the number of roofing squares for the roof. 1square of roofing covers 100 square feet of roof a bundle is 1 3 of a square. A square of shingles is the number of shingles needed to cover 100 sq feet of roof area. 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.

A roof s pitch is determined by how much it rises vertically for every foot it runs horizontally. 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. This is simply 100 square feet of roof. To find the squares divide the overall roof area by 100 and then round up.

A square simply refers to a 10 x 10 square of roofing. 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. Enter square footage calculate or enter the square footage of the attic or area to be vented.
