"Is Tin Cheaper Than Asphalt Roofing?" depends on a number of variables, such as cost, longevity, and long-term advantages. With costs ranging from $3.50 to $5.50 per square foot, asphalt shingles are often less expensive up front. However, tin roofing can cost as much as $4 per square foot, depending on the type of metal used. Tin roofs are more expensive initially, but over time, their longevity (up to 50 years or more), energy efficiency, and reduced maintenance costs may make them more affordable. However, asphalt shingles might need to be replaced more frequently. When choosing the ideal alternative for your needs, take into account the local climate and your long-term objectives.
