A properly installed metal roof can last a long time, you can usually expect a metal roof to last at least 2 to 3 times longer than a regular roof. A lot of metal roof installations come with warranties that can last anywhere from 20 to 50 years or longer. Another advantage of metal making it last longer is it can be repainted rather than having to be replaced if it starts to fade. The average lifespan of an asphalt roof is 12 to 20 years, which can be shorter depending on the pitch of your roof and your climate. These roofs are fire resistant, and insects such as termites can never eat through metal roofing. This type of roofing is also impervious to rot and mildew, making sure it retains its good look and durability. Not only is metal roofing a fantastic option for your home, it helps the environment too. The recycled content of a metal roof is around 28% and is completely recyclable at the end of it’s lifespan, making metal roofing a green building material!
