For instance a 7 12 roof pitch means that the roof rises 7 inches for every 12 horizontal inches.
Roof square 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.
The answer is the number of roofing squares for the roof.
This gives us a 3d roof area of 1 625 sq ft.
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.
Estimate the pitch of the roof.
More upscale metal roofs such as standing seam panels and stone coated metal shingles cost 8 5 14 75 per square foot.
Roofing material is estimated by the square which is equal to 100 square feet.
The average price for metal roofing shingles is 8 35 per square foot.
This is simply 100 square feet of roof.
1square of roofing covers 100 square feet of roof a bundle is 1 3 of a square.
It will display 3 figures.
Low average and high figures for the estimator tool.
In general metal roofing has enjoyed a major spike in popularity over the last decade.
Outside of the u s a degree angle is typically used.
Roof replacement or repair.
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.
Steep roofs measure your house at ground level then add in the roof s overhang for greater accuracy.
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 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.
The average roof is 3 000 square feet or around 30 squares.
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.
You will need to express this size in terms of square feet.
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.
