We bought an old home that needed reroofing and decided on a metal roof for various reasons. I checked around, and these guys had really good prices.
They do most of their business with contractors, but they sell to us do-it-yourselfers, too.
They walked me through how to take measurements to order the material, then after it arrived, they walked me through how to install it.
We couldn't have done it without them!
Especially Jim - he really took the time to explain things and was a pleasure to work with!
