Several factors go into the cost of a roof, beginning with your choice of roofing materials (ranging from cheap three-tab asphalt shingles up to architectural shingles or even slate). The roofing contractor you choose, the pitch (steepness or your roof), and the square footage of your roof are other factors that affect the cost. Rock-bottom, a three-tab composite roof for a small home may cost as little as $7,000. Nationally, a typical roof using architectural asphalt shingles costs between $3.50 and $5.50 per square foot—a cost that includes all demolition, permit fees, waste disposal, and cleanup.
