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.
Roof square footage estimator.
It will display 3 figures.
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.
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.
Using this tool will be very helpful for you in finding out the acreage or the tract of land of your property.
Measure the perimeter of the roof enter the pitch and get the total sum of squares.
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.
So multiply length a x width b to get the square footage for each plane.
For the total square footage of the roof.
A square simply refers to a 10 x 10 square of roofing.
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.
1square of roofing covers 100 square feet of roof a bundle is 1 3 of a square.
It will also give you the perimeter of the shape of the roof.
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.
This gives us a 3d roof area of 1 625 sq ft.
Low average and high figures for the estimator tool.
It will also give you the square footage of your roof and any other areas that you re wanting to estimate.
To find the squares divide the overall roof area by 100 and then round up.
Using the aggregate area of these simple shapes can yield a more accurate roof area to be used with the roofing material calculator.
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.
This is simply 100 square feet of roof.
Plane 1 plane 2 24 000 sq.
The first step in a free roofing estimate is measuring the roof dimensions.
You can even embed this tool on a website that you own.
Now assuming an average pitch of 9 12 we multiply the 2d area of 1 300 by 1 25.
For instance if the roof is 1550 square feet then it is 16 squares.
