Total Surface Area Of A Roof

With a single pitch roof you ll have only one area result that relates to the entire footprint or perimeter of the roof.

Total surface area of a roof.

Online calculators and formulas for a surface area and other geometry problems. 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. The roof slope height is 6 98m. Because this is only one half of the roof we will need to double this number to find the entire roof area 121 45m.

Divide the area you calculated in step 4 by 100. 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. Both metric and imperial measurement systems are displayed in a popup menu over the results area. 8 7m x 6 98m 60 73m.

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. Whether it is for a renovation or just for a building inspection purpose. So for our example the half roof area is as follows.

Steep roofs measure your house at ground level then add in the roof s overhang for greater accuracy. Calculate the unknown defining side lengths circumferences volumes or radii of a various geometric shapes with any 2 known variables. 6 calculate the total surface area of the roof using the following formula. That gives you 5 590 square feet which is the actual area of the surface of the roof.

Pi times the radius times the rafter length also. This applies to lengths as well as areas. Once you have your roof s pitch divide the number by 12. The length of the roof is 8 7m for this square house as 8 7m x 8 7m is 76m total floor space.

Do you know how to measure the surface area of a simple gable or hip roof. Take the area of the roof s footprint say it s 5 000 square feet and multiply 5 000 by 1 118. 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 answer to this is the total number of squares on your roof for which you need to purchase shingles.

Multiply this number by your most recent result to get the estimated square footage of your 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.
