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).
In terms of a ballpark figure, though, Michael Allen, owner of Above It All Roofing in Irvine, California, says the average cost of a new roof runs as low as $5,000 for a basic asphalt shingle roof â the most commonly used roofing material in America â to $25,000 and up for higher-end roof types.
