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.
Ways to figure sq ft of roof.
1square of roofing covers 100 square feet of roof a bundle is 1 3 of a square.
This is simply 100 square feet of roof.
Divide any irregularly shaped areas of the roof into more manageable triangles and rectangles then calculate square footage for those individual elements and add them to get the total square footage.
Assuming a single story rectangular house with a hip roof that has two foot overhangs on each side of the house we have approximately 13 squares or 1 300 square feet of 2d roof surface area.
You will need to express this size in terms of square feet.
