Total Surface Area Of A Roof

Divide the area you calculated in step 4 by 100.

Total surface area of a roof.

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. The answer to this is the total number of squares on your roof for which you need to purchase shingles. Calculator online for a the surface area of a capsule cone conical frustum cube cylinder hemisphere square pyramid rectangular prism triangular prism sphere or spherical cap. 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.

8 7m x 6 98m 60 73m. Both metric and imperial measurement systems are displayed in a popup menu over the results area. The length of the roof is 8 7m for this square house as 8 7m x 8 7m is 76m total floor space. Online calculators and formulas for a surface area and other geometry problems.

This applies to lengths as well as areas. Because this is only one half of the roof we will need to double this number to find the entire roof area 121 45m. Once you have your roof s pitch divide the number by 12. That gives you 5 590 square feet which is the actual area of the surface of the roof.

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. The roof slope height is 6 98m. In the construction industry roofs are measured in squares one square equals 100 square feet. Measure the length of the rafters from the peak to the lower edge.

Steep roofs measure your house at ground level then add in the roof s overhang for greater accuracy. Take the area of the roof s footprint say it s 5 000 square feet and multiply 5 000 by 1 118. Whether it is for a renovation or just for a building inspection purpose. With a single pitch roof you ll have only one area result that relates to the entire footprint or perimeter of the roof.

6 calculate the total surface area of the roof using the following formula. Pi times the radius times the rafter length also. Do you know how to measure the surface area of a simple gable or hip roof. So for our example the half roof area is as follows.

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. Calculate the unknown defining side lengths circumferences volumes or radii of a various geometric shapes with any 2 known variables.
