Is Tin Cheaper Than Asphalt Roofing? A number of things influence the cost differential. Asphalt roofing typically costs between $3.50 and $5.50 per square foot, making it less expensive up front. The cost of tin or metal roofing varies by material, ranging from $4 to $30 per square foot. But over time, tin roofs may save money since they are more energy-efficient, endure longer, and require less upkeep. Asphalt shingles may require replacing sooner even though they are initially less expensive. Your decision is based on your long-term goals for your house, durability requirements, and financial constraints.
