Roof Estimate Per Square

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.

Roof estimate per square.

To find the squares divide the overall roof area by 100 and then round up. A square simply refers to a 10 x 10 square of roofing. Now assuming an average pitch of 9 12 we multiply the 2d area of 1 300 by 1 25. 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.

Steep roofs measure your house at ground level then add in the roof s overhang for greater accuracy. The calculator cannot account for complex shapes based on a measurement of square footage alone. This is simply 100 square feet of roof. This gives us a 3d roof area of 1 625 sq ft.

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. 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. Low average and high figures for the estimator tool. You will need to express this size in terms of square feet.

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. Select the appropriate price per square then enter it into the roof calculator program for a fast and accurate estimate. 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.
