While the upfront costs of installing a metal roof are often higher than shingles, a metal roof lasts longer and will be replaced or repaired far less frequently. A typical shingle roof lasts anywhere from 12 to 20 years, depending upon how well it’s maintained and weather elements it may encounter. Metal roofs, on the other hand, can last between 40 and 60 years while also requiring less maintenance, making them a more cost-effective choice over the lifespan of the roof.
