I highly recommend Gallagher Brothers Construction Company. Doing a recent storm our roof was damaged. Gallagher came out inspected our roof and notified us of the damage. They gave us plenty of options to consider for a roof repair. Rex walked us through every step of the way and, made me and my wife feel very comfortable with no pressure to upgrade any services. When they came to put on our new roof they covered the flowers and bushes to protect them. When they where done with the cleaned up ran magnets to get any loose nails and materials. We love the look of our new roof. This was one of the best experiences that we have had in a long time involving contractors. We will definitely recommend them to family and friends.

Jimmy from GB was very professional and helpful. He inspected my roof and gutters. Very straightforward about condition stating all looked well, no need for any repairs at this time. Hard to find a company that doesn't use uncertainty and doubt to push unnecessary repairs. I respect and highly recommend this company. Doug
