How Do You Find The Square Footage Of A Roof

For instance if the roof is 1550 square feet then it is 16 squares.

How do you find the square footage of a roof.

The length l times the height h of a triangle is twice its area a2. L h 2 area calculating an area of a triangle when estimating a roof. To find the squares divide the overall roof area by 100 and then round up. Things you will need steel tape measure.

If you measured in another unit of measure do the following to convert to feet. Enter the length of the building. The first step in a free roofing estimate is measuring the roof dimensions. If you measured in feet inches divide inches by 12 and add that to your feet measure to get total feet.

If for example the total square footage for the examples used so far would be 14 400 the rectangular plane plus 900 the triangle plus 2 000 the irregular shape 17 300 square feet. While it is possible to estimate the amount of necessary materials using only the total roof area measurement as can be seen from the table depending how large the pitch of the roof the actual area of the roof can differ by up to 2 236 from the measured total area at a pitch of 24 12. You will need to express this size in terms of square feet. Rise 12 enter the lower pitch length.

As such while it can be cumbersome measuring the area and pitch of each part of the roof and multiplying by the corresponding correction factor will result in the most accurate estimate of necessary. Inches enter the pitch of the upper roof rise 12 enter the pitch of the lower roof. The result is the total square footage of your roof. Using this tool will be very helpful for you in finding out the acreage or the tract of land of your property.

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. Steep roofs measure your house at ground level then add in the roof s overhang for greater accuracy. It will also give you the square footage of your roof and any other areas that you re wanting to estimate. So if you divide your answer of a product of length times height by two you will get the area of a triangle.

This is simply 100 square feet of roof. Feet inches enter the width of the building. If you measured in feet skip to calculate the area as square footage. You can even embed this tool on a website that you own.

Feet inches enter the overhang of the eaves. 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. 1 roof square 100 square feet. A square simply refers to a 10 x 10 square of roofing.

Convert all of your measurements to feet. Add the square footage for all the planes together.
