Which roof type provides a cost benefit over a 30 year period and how much is that benefit? (HINT: find the difference between the 30 yr costs)

A metal roof provides a cost benefit over a 30 year period compared to an asphalt shingle roof. The average cost of a metal roof is around $12,000, while the average cost of an asphalt shingle roof is around $6,000.

Over a 30 year period, the maintenance costs and lifespan of a metal roof make it a more cost-effective option. On average, an asphalt shingle roof needs to be replaced every 15-20 years, costing around $6,000 each time. In comparison, a metal roof can last up to 50 years or more, meaning it would only need to be replaced once in a 30 year period.

Therefore, the cost benefit of choosing a metal roof over an asphalt shingle roof over 30 years would be approximately $6,000 (the cost of a new asphalt shingle roof every 15-20 years).
