Roof Square Estimate

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

Roof square estimate.

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. A square simply refers to a 10 x 10 square of roofing. 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. It will display 3 figures.

Outside of the u s a degree angle is typically used. Because each 100 square feet of roof is one roofing square divide the total area from step 1 by 100. To find the squares divide the overall roof area by 100 and then round up. Estimate the pitch of the roof.

Low average and high figures for the estimator tool. The average roof is 3 000 square feet or around 30 squares. For instance a 7 12 roof pitch means that the roof rises 7 inches for every 12 horizontal inches. 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.

In the united states a run of 12 inches 1 foot is used and pitch is measured as the rise of the roof over 12 inches. Roof replacement or repair.

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

1square of roofing covers 100 square feet of roof a bundle is 1 3 of a square. More upscale metal roofs such as standing seam panels and stone coated metal shingles cost 8 5 14 75 per square foot. Get the square footage of roof and divide it by 100 and it will give the number of squares you need and for every decimal number over 3 buy a bundle to achieve the amount of material. The average price for metal roofing shingles is 8 35 per square foot.

The answer is the number of roofing squares for the roof. In general metal roofing has enjoyed a major spike in popularity over the last decade. 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. For estimating purposes we also assume that there is a chimney a couple of dormers and two layers of old shingles that need to be torn off and removed before a new roof can be installed.

This gives us a 3d roof area of 1 625 sq ft.
