Metal Myth 5.
The roof will rust and need to be replaced.
Actually, a metal roof could be the last roof you ever need to purchase. They last 50-plus years, nearly two to three times longer than asphalt. And, metal roof coatings naturally resist rust, moss, and fungus, keeping your roof in great shape for decades.
After a metal roof’s long life, it can be recycled rather than dumped into the landfill.
