Roof Square Footage Calculator

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.

Roof square footage calculator.

If the surface is complex in shape it may be possible to section the surface into simple shapes and add their square footages together. Roof surfaces are measured in squares a square is an area of roof which measures 100 square feet. Roof shingles are figured by number of squares. With the area measurement you.

This calculator will help you determine the amount of square feet you have for replacing roof shingles. 10 x10 100sf 1 square for each of the roof types pictured below l horizontal length w horizontal width and h vertical height all entered in feet. Keep in mind that the average size of a roof is 1 700 square feet so your total will likely be 10 higher or lower than this figure. The base width is the distance from one corner of your roof to the other at its base on the short side of your house.

Plane 1 plane 2 24 000 sq. Using the aggregate area of these simple shapes can yield a more accurate roof area to be used with the roofing material calculator. Now assuming an average pitch of 9 12 we multiply the 2d area of 1 300 by 1 25. This gives us a 3d roof area of 1 625 sq ft.

Calculate square footage for a roof by measuring and by performing some basic math equations. To determine the number of squares on the gable roof above simply divide its total of 24 000 square feet by 100. 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. The base length is simply the distance from the second corner to the third corner on the house s long side.

Both the roof area and pitch contribute to the cost of a roofing job. For the total square footage of the roof. The calculator cannot account for complex shapes based on a measurement of square footage alone. Our roof calculator uses base length and base width to find the estimated area.
