Metal roofs can last a lot longer than traditional asphalt or composite roofing, lasting around 40-70 years depending on the material you choose.
Metal roofs will not spark and ignite into flames during a wild fire or a lightning strike. "Most metal roofing carries a Class A fire-resistant rating, the highest possible. If you live in an area prone to wildfires, a metal roof is the number one home investment you can make. A common cause of residential fires is due to wind-blown embers, which can travel up to a mile and become lodged in between shingles. Unlike wood shake or petroleum-based asphalt roofs, metal is inherently non-combustible and offers a high degree of fire protection for your entire home."

Some metal roofs can sustain wind gusts up to 140 miles per hour, will not corrode, crack, or rot; metal roofs can easily shed snow, and may be impact-resistant (depending on which metal you choose). In addition, metal roofs don't need the periodic costly maintenance that other roofing materials often require.
Metal roofs reflect solar radiant heat, which can reduce cooling costs by 10-25%.
Metal roofs not only have 25-95% recycled content, depending on the material used, but are also 100% recyclable at the end of their life as a roof. In contrast, most shingle tear-off waste ends up as part of the building-related waste stream — up to 20 billion pounds per year.
