 Your high-tech solution. 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.
