That gives you 5 590 square feet which is the actual area of the surface of the roof.
Total surface area of a roof.
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.
And that s the number you were looking for.
So for our example the half roof area is as follows.
Whether it is for a renovation or just for a building inspection purpose.
Divide the area you calculated in step 4 by 100.
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.
6 calculate the total surface area of the roof using the following formula.
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.
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.
The length of the roof is 8 7m for this square house as 8 7m x 8 7m is 76m total floor space.
Once you have your roof s pitch divide the number by 12.
Do you know how to measure the surface area of a simple gable or hip roof.
The roof slope height is 6 98m.
Pi times the radius times the rafter length also.
Both metric and imperial measurement systems are displayed in a popup menu over the results area.
Because this is only one half of the roof we will need to double this number to find the entire roof area 121 45m.
Calculate the unknown defining side lengths circumferences volumes or radii of a various geometric shapes with any 2 known variables.
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.
This applies to lengths as well as areas.
The answer to this is the total number of squares on your roof for which you need to purchase shingles.
Take the area of the roof s footprint say it s 5 000 square feet and multiply 5 000 by 1 118.
With a single pitch roof you ll have only one area result that relates to the entire footprint or perimeter of the roof.
In the construction industry roofs are measured in squares one square equals 100 square feet.
