A metal roof is a type of roof made out of metal. Metal roofs are usually made of steel or aluminum, but can also be made of copper, zinc or other metals. Metal roofs are strong, light, and generally last much longer than other types of roofs. They can hold up better against strong winds, bad weather, and they won’t rot or crack like other types of roofs, making them a good long-term choice. Metal roofs also reflect heat, so they can keep your home cool in the summer, saving you money on energy bills.
