Figure Sq Ft Of Roof

For the total square footage of the roof.

Figure sq ft of roof.

The answer is the number of roofing squares for the roof. 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. A square simply refers to a 10 x 10 square of roofing.

This is simply 100 square feet of roof. As a rule of thumb there are 3 bundles to a square assuming that you are using three tab strip shingles. A square of shingles is the number of shingles needed to cover 100 sq feet of roof area. To determine the number of squares on the gable roof above simply divide its total of 24 000 square feet by 100.

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. 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. A roof s pitch is determined by how much it rises vertically for every foot it runs horizontally. Plane 1 plane 2 24 000 sq.

Multiply the square footage of your roof by 1 to get the 10 percent waste allowance. The total amount of roofing material you need is 17 300 1 730 19 030 square feet. To find the squares divide the overall roof area by 100 and then round up. 1square of roofing covers 100 square feet of roof a bundle is 1 3 of a square.

Thus a moderate 6 in 12 roof pitch means that the roof rises 6 inches vertically for every 12 horizontal inches it runs. Convert the area to roofing squares. Because each 100 square feet of roof is one roofing square divide the total area from step 1 by 100. Roof surfaces are measured in squares a square is an area of roof which measures 100 square feet.

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. 120 x 100 12 000 sq.
