How many square foot is a average house roof. According to your calculator my actual square feet of house is 4807 5 numbers of squares needed is 53. Measure your house at ground level then add in the roof s overhang for greater accuracy. Take that to a 12 12 pitch and the actual roof square footage goes up to assuming peaked along the 100 dimension 3896 sf. 3698 sq ft with predominant 10 12 pitch.

The average home size in the us is 2500 square feet. So before i start breaking things down let me say that in 2018 the average cost for roof replacement for a 2500 square foot home is 8500 to 11500. Many homes have an asphalt shingle roof but some have wood metal tile and slate which can be more expensive. Convert the area to roofing squares.

The majority of homes in the us have an asphalt shingle roof. Shingles and other roofing materials such as underlayment are typically measured in squares that are 10 feet long and 10 feet wide with each square measuring 100 square feet.

To find the squares divide the overall roof area by 100 and then round up. The average roof is 3 000 square feet or around 30 squares. This nominal square footage amount is then multiplied by a factor associated with the roof s pitch. For instance a 20x100 house with 3 foot overhangs would have 26x106 foot plan on the roof or 2756 sf for a flat roof.

This is simply 100 square feet of roof. Average would not be a real meaningful number depends too much on the overhang and the shape of the house and roof slope. Because each 100 square feet of roof is one roofing square divide the total area from step 1 by 100.
