Townhouse roofing estimate.
For an average roof of 17 squares according to the united states census which puts average home size at 2 200 square feet and two stories roofing materials typically range from 2 500 to 25 000.

Roofing material is estimated by the square which is equal to 100 square feet.
Now assuming an average pitch of 9 12 we multiply the 2d area of 1 300 by 1 25.
For example an asphalt estimate for property sitting on 1 200 square foot is comparatively lower to that of metal that goes for a higher sum.
Thus a 3 tab composition shingle roof will cost an average of 350 to 450 per square to install.
