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. As an example if your overhang is 12 inches you ll add 2 feet to the overall length and 2 feet to the overall width of the house. 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. 3698 sq ft with predominant 10 12 pitch. Outside of the u s a degree angle is typically used. The answer is the number of roofing squares for the roof.

Because each 100 square feet of roof is one roofing square divide the total area from step 1 by 100.

Roof pitches in. The average roof is 3 000 square feet or around 30 squares. Convert the area to roofing squares. A square simply refers to a 10 x 10 square of roofing.

Check that your footage measurements are within this range so you can start off on the right foot. Average would not be a real meaningful number depends too much on the overhang and the shape of the house and roof slope. For instance a 7 12 roof pitch means that the roof rises 7 inches for every 12 horizontal inches. It is often compared to slope but is not exactly the same.

When calculating square footage for your roof always add at least 10 percent of the total to account for waste. To find the squares divide the overall roof area by 100 and then round up. Take that to a 12 12 pitch and the actual roof square footage goes up to assuming peaked along the 100 dimension 3896 sf. 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.

For instance if the roof is 1550 square feet then it is 16 squares. According to your calculator my actual square feet of house is 4807 5 numbers of squares needed is 53. Roofing material is estimated by the square which is equal to 100 square feet.
