Whomever you choose, be sure you get gutters that are the correct size for the surface area and pitch of your roof. We have a 9/12 pitch and a massive surface area, we had standard 5" gutters put on our house and we should have had 6" gutters put on. Since ours was part of the package with a new build we were not advised of any options we had as far as gutter choices. By the time the gutters were going on the house we were much more concerned with actually setting a move in date. Live and Learn.
