Roof Square Footage Calculator

The first step in a free roofing estimate is measuring the roof dimensions.

Roof square footage calculator.

The calculator cannot account for complex shapes based on a measurement of square footage alone. 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. Our roof calculator uses base length and base width to find the estimated area. Using the aggregate area of these simple shapes can yield a more accurate roof area to be used with the roofing material calculator.

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. Calculator use use this calculator to find the square footage square yardage square meters or acres for a building home garden or construction project. You will need to express this size in terms of square feet. The area calculator can be used to calculate the area of a variety of simple shapes that together can comprise the area of the roof.

Low average and high figures for the estimator tool. Calculate square footage for a roof by measuring and by performing some basic math equations. Plane 1 plane 2 24 000 sq. Roof surfaces are measured in squares a square is an area of roof which measures 100 square feet.

Calculate square footage yardage meters and acres for landscape flooring carpet or tiling projects to estimate area and the amount of material you will need. If the surface is complex in shape it may be possible to section the surface into simple shapes and add their square footages together. 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. 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.

Roof shingles are figured by number of squares. The base length is simply the distance from the second corner to the third corner on the house s long side. This gives us a 3d roof area of 1 625 sq ft. 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.

Both the roof area and pitch contribute to the cost of a roofing job. The square footage calculator estimates the square footage of a lot house or other surfaces in several common shapes. To determine the number of squares on the gable roof above simply divide its total of 24 000 square feet by 100. This calculator will help you determine the amount of square feet you have for replacing roof shingles.

Now assuming an average pitch of 9 12 we multiply the 2d area of 1 300 by 1 25.
