Is Tin Cheaper Than Asphalt Roofing? Many factors determine the cost difference. At $3.50 to $5.50 per square foot, asphalt roofing is typically less expensive up front. Depending on what is used, tin or metal roofing might cost anywhere from $4 to $30 per square foot. Tin roofs, on the other hand, are more energy-efficient, require less upkeep, and remain functional longer, which could result in long-term cost savings. Although initially inexpensive, asphalt shingles may require replacing sooner rather than later. Your decision is influenced by the objectives you have for your house, durability requirements, and money.
