This review is for a standing seam steel roof done a few years ago, along with soffits, fascia, and siding.
The good: the crew doing the roof did a good job - they definitely cared about their work and took pride in doing things properly. The estimator I dealt with (as well as Lucas himself) were very knowledgeable and addressed any questions and concerns.
The bad: there were a few minor issues with the way things were done: The ice & water shield they had intended to use was not suitable for use under a metal roof - it was the standard stuff with a textured, sandpaper-like coating, which would do terrible things to the underside of the metal panels (which expand & contract with temperature changes). They "upgraded" to Soprema a product (at my expense) when I pointed this out. They also didn't space the soffits/siding properly, so they had to run a bead of caulk down all of the connections - I had hoped to avoid exactly such issues by hiring them do both the soffits and the siding.
Overall, I was relatively pleased, as I had a very hard time finding any company that inspired much confidence in their ability to install a metal roof properly - I realize it's much more involved than nailing down shingles. The roof work was generally pretty good, and there have been no signs of obvious signs of leaks or other problems.
