Roof Estimate Per Square

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.

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. 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. This is simply 100 square feet of roof. It will display 3 figures.

For instance say the numbers used in the over 9 12 above might be sufficient for a particular roof but for a cut up roof 2 stories to the eave with bad access these numbers would be way too low. Select the appropriate price per square then enter it into the roof calculator program for a fast and accurate estimate. Now assuming an average pitch of 9 12 we multiply the 2d area of 1 300 by 1 25. Low average and high figures for the estimator tool.

This gives us a 3d roof area of 1 625 sq ft. You will need to express this size in terms of square feet. A square simply refers to a 10 x 10 square of roofing. The first step in a free roofing estimate is measuring the roof dimensions.

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