"Is Tin Cheaper Than Asphalt Roofing?" is a question that many homeowners have when choosing between tin and asphalt roofing. Tin (metal) roofing has long-term advantages that might offset the initial expense, even though asphalt shingles are often less expensive up front. Asphalt roofs usually last 20 to 30 years, while metal roofs have lifespans of 40 to 70 years. By reflecting solar heat, tin roofs can improve energy efficiency and may lower cooling expenses. For some households, tin is a sensible investment since, despite its initial higher cost, it can result in long-term cost savings on repairs and energy expenses.
