Roof Estimate Per Square

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 estimate per square. 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. Costs can vary widely depending on how complex your roofing structure is type of roofing material overall slope number of chimneys sky lights taxes permits and other roof structures not listed. A square simply refers to a 10 x 10 square of roofing. This gives us a 3d roof area of 1 625 sq ft.

Select the appropriate price per square then enter it into the roof calculator program for a fast and accurate estimate. To find the squares divide the overall roof area by 100 and then round up. Steep roofs measure your house at ground level then add in the roof s overhang for greater accuracy. 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.

The calculator cannot account for complex shapes based on a measurement of square footage alone. Low average and high figures for the estimator tool. The first step in a free roofing estimate is measuring the roof dimensions. This is simply 100 square feet of roof.

It will display 3 figures. Now assuming an average pitch of 9 12 we multiply the 2d area of 1 300 by 1 25. 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. 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.
