How Do I Estimate The Square Footage Of My Roof

The answer is the number of roofing squares for the roof.

How do i estimate the square footage of my roof. Square the result of step 1. Roof area measured in sq ft number of squares. Roof width measured in feet roof pitch. It will also show the perimeter of the shape.

Each time you add points the area will update and there is a box below that will convert this into acres meters kilometers miles and finally square feet. Approximate price in dollars the estimate of a final price will depend to a large degree on the overall size of your home i e. Divide any irregularly shaped areas of the roof into more manageable triangles and rectangles then calculate square footage for those individual elements and add them to get the total square footage. For example take an area made up of a triangle that s 20 feet high and has a base of 40 feet plus a square that s 40 feet by 40 feet.

Adding 1 gives us 1 1 9 10 9 then taking the square root gives us about. Flat roofs if your roof is flat or has no more than a 3 in 12 pitch you can calculate its total square footage by simply multiplying the length by the width. So keeping with our roof pitch of 4 this gives us 1 9. Because each 100 square feet of roof is one roofing square divide the total area from step 1 by 100.

Convert the area to roofing squares. For example this shed roof has one roof plane. The calculator cannot account for complex shapes based on a measurement of square footage alone. Add 1 then take the square root.

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. Roof type either gable or hip using these four inputs you will get several basic outputs. This tool is useful for finding the approximate acreage or a tract of land the square footage of a roof or any other instance where you need a good estimate of the area of something. To do this measure the length and width of each plane on the roof including dormers.

If your roof measures 48 feet 15 m x 24 feet 7 3 m multiplying its length by its width would give you a square footage of 1 152 square feet 107 0 m 2. Finally calculate your roof s total square footage by simply adding the square footage of each of the planes together. It will also give you the perimeter of the shape of the roof. After you ve done this you can click along the outer edge of the roof that you wish to calculate the area for.

Steep roofs measure your house at ground level then add in the roof s overhang for greater accuracy.
