Total Surface Area Of A Roof

1 300 x 1 05 1 365 square feet calculating the area true if you want to get the exact area measurement for your roof you can follow these steps.

Total surface area of a roof.

That gives you 5 590 square feet which is the actual area of the surface of the roof. This applies to lengths as well as areas. 8 7m x 6 98m 60 73m. Steep roofs measure your house at ground level then add in the roof s overhang for greater accuracy.

Divide the area you calculated in step 4 by 100. Pi times the radius times the rafter length also. Because this is only one half of the roof we will need to double this number to find the entire roof area 121 45m. Do you know how to measure the surface area of a simple gable or hip roof.

The length of the roof is 8 7m for this square house as 8 7m x 8 7m is 76m total floor space. Take your area result and multiply it by the pitch multiplier or slope correction factor found in the table above to arrive at the roof s surface area. 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. Multiply this number by your most recent result to get the estimated square footage of your 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. 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. Take the area of the roof s footprint say it s 5 000 square feet and multiply 5 000 by 1 118. Measure the length of the rafters from the peak to the lower edge.

With a single pitch roof you ll have only one area result that relates to the entire footprint or perimeter of the roof. Whether it is for a renovation or just for a building inspection purpose. So for our example the half roof area is as follows. Calculate the unknown defining side lengths circumferences volumes or radii of a various geometric shapes with any 2 known variables.

And that s the number you were looking for. Once you have your roof s pitch divide the number by 12. The answer to this is the total number of squares on your roof for which you need to purchase shingles.
