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).
Note: many professional roofing contractors price their roofs on a per square basis, where one square is a 10 by 10 foot area or 100 square feet. Thus, your total cost in square terms could range from $350 to $1,200 per square of metal roofing installed. For comparison, most asphalt shingle roofs will cost anywhere from $300 to $700 per square installed depending on the material choice, roof complexity, installerâs credentials, your geographic area, time of the year, and so forth.
