How Many Square Foot Is A Average House Roof

Measure your house at ground level then add in the roof s overhang for greater accuracy.

How many square foot is a average house roof. Roof pitches in. Roofing material is estimated by the square which is equal to 100 square feet. 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. This nominal square footage amount is then multiplied by a factor associated with the roof s pitch.

The answer is the number of roofing squares for the roof. The average roof is 3 000 square feet or around 30 squares. The majority of homes in the us have an asphalt shingle roof. Because each 100 square feet of roof is one roofing square divide the total area from step 1 by 100.

For instance if the roof is 1550 square feet then it is 16 squares. Outside of the u s a degree angle is typically used. A square simply refers to a 10 x 10 square of roofing. 3698 sq ft with predominant 10 12 pitch.

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. 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 a 7 12 roof pitch means that the roof rises 7 inches for every 12 horizontal inches. Take that to a 12 12 pitch and the actual roof square footage goes up to assuming peaked along the 100 dimension 3896 sf. The numbers i used are based on the proposal from my roofer. Many homes have an asphalt shingle roof but some have wood metal tile and slate which can be more expensive.

In the united states a run of 12 inches 1 foot is used and pitch is measured as the rise of the roof over 12 inches. To find the squares divide the overall roof area by 100 and then round up. When calculating square footage for your roof always add at least 10 percent of the total to account for waste. The average home size in the us is 2500 square feet.

Average would not be a real meaningful number depends too much on the overhang and the shape of the house and roof slope. According to your calculator my actual square feet of house is 4807 5 numbers of squares needed is 53. It is often compared to slope but is not exactly the same.
