Type of Roofing Material. After roof size, the type of roofing material is the most significant factor in determining the average roof replacement cost. Asphalt shingles are the least expensive roofing material, with starting costs at under $1,000. Metal roofing is the most expensive and can cost up to $30,000-$40,000 for large roof replacements. The quality of the roofing material will also determine the cost of roof replacement. For example, asphalt shingles can cost anywhere from $50 for average quality to $150 or more for the highest quality (per square).
New Roof Costs. 1  An asphalt shingle roof starts at $2 to $4 per square foot installed and might cost as much as $5 to $8 per square foot installed. 2  On a 1,500 square foot roof, that's a total estimated cost of $3,000 to $12,000. Wood shingles cost $6 to $9 per square foot installed ($9,000 to $13,500). 2  Galvanized steel is one of the most popular metal roof options and costs $9 to $13 per square foot installed ($13,500 to $19,500).
