 It could be an asphalt roof or a metal roof, and you've actually had them work on both different properties. On a regular occasion, yeah. The biggest challenge for me, because it was my own personal roof, was the metal roof. Because when I bought it, the guys like the guy I bought it from, the roof salesman, said, hey, you'll never put another roof on your house because it's a metal roof. However, you've got to make sure you maintain it.
