A lot of factors contribute to the cost of a new roof. The quality of the shingles being used, the steepness of your roof, and your location in the country can all affect the final cost. On average, composite roofing materials can cost between $100 to $300 per square (100 square feet). An average roof may use about 20 squares of roofing materials, meaning a materials cost of $2,000 to $6,000 for a 2,000 square foot roof. Labor cost may also include stripping away the old roof and disposing of the old materials. The average cost of a new composite roof varies depending on the region of the county. In the southeast and Midwest, roofs are usually less than $10,000. Higher quality roofing materials, such as hurricane resistant roofs in the southeast can cost a little more.
The actual cost of an asphalt shingle roof may vary depending on the materials used, your location, the complexity of the installation (i.e. roof slope and home height), and other factors. 1  3-Tab asphalt shingles cost $1.50 to $3.50 per square foot. For an average-sized (1,500 square foot roof), the total cost might be $2,250 to $5,250. Architectural asphalt roof shingles cost, on average, cost around 20 to 40 percent more than 3-Tab shingles, or $2.50 to $5.00 per square foot installed ($3,750 to $7,500). High end architectural shingles, however, could run as much as $6 to $8 per square foot installed ($9,000 to $12,000).
