 After all the hail and high winds we've had, all of the roofs that have been damaged this year, many homeowners might be looking for alternatives to traditional shingles. There's a lot of options out there. Mike Wells with RainTech Roofing Sheet Metal and Gutters says one option is to have RainTech install a metal roof. But Mike cautions metal roofs can last 50, 60 years, longer than most people need or want to pay for. It's not for everybody, but it is a very good option on a class four impact rated roof.
