To find the squares divide the overall roof area by 100 and then round up.
Roof square footage estimator.
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.
Plane 1 plane 2 24 000 sq.
It will also give you the perimeter of the shape of the roof.
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.
1square of roofing covers 100 square feet of roof a bundle is 1 3 of a square.
For instance if the roof is 1550 square feet then it is 16 squares.
You will need to express this size in terms of square feet.
The calculator cannot account for complex shapes based on a measurement of square footage alone.
The first step in a free roofing estimate is measuring the roof dimensions.
Steep roofs measure your house at ground level then add in the roof s overhang for greater accuracy.
The area calculator can be used to calculate the area of a variety of simple shapes that together can comprise the area of the roof.
Then add the two planes together to derive the total square footage of the roof.
Now assuming an average pitch of 9 12 we multiply the 2d area of 1 300 by 1 25.
This is simply 100 square feet of roof.
A square simply refers to a 10 x 10 square of roofing.
For the total square footage of the roof.
Using the aggregate area of these simple shapes can yield a more accurate roof area to be used with the roofing material calculator.
Using this tool will be very helpful for you in finding out the acreage or the tract of land of your property.
120 x 100 12 000 sq.
You can even embed this tool on a website that you own.
So multiply length a x width b to get the square footage for each plane.
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.
It will display 3 figures.
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.
120 x 100 12 000 sq.
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.
