Both metal and asphalt shingle roofs have advantages and disadvantages depending on your needs. Strictly on price and budget, an asphalt shingle roof is often cheaper than a metal roof in the short-term. However, since an asphalt shingle roof may need to be replaced twice in the lifecycle of a metal roof, over the long-term a metal roof can be more cost-effective. An asphalt shingle roof may last 15-25 years, while a metal roof can last 50 years, giving metal the edge for longevity. Surprising to many people, metal roofs are also more lightweight than shingles, and perform well when exposed to intense storm conditions.
