Customers describe GRB Roofing as the best. Team members are super knowledgeable, professional, timely, and always providing updates throughout the process. Crews did great work in repairing houses and making them better than before. One team member came out the same day a call was made and, even though the issue was not a job they would handle, still took the time to look at the attic, answered concerns and referred a person that could help. The technician was quick, very courteous, and knowledgeable. During estimates, the team was honest, shared a lot of information and answered questions with no pressure to agree to anything. GRB coordinated solar panel removal and reinstallation with an authorized solar contractor so it was seamless. Roofing shingles and gutter replacement projects were completed in a day. The price was fair and customers were very impressed with the end result, with exceptional curb appeal that's the envy of the neighborhood. GRB Roofing comes highly recommended.

I contacted a half dozen roofing companies to get estimates for our 18 year old roof replacement. Some didn't even bother to respond, another just played with a drone showing images that were too far away to be of any value, another said it looked okay and didn't need replacing just looking at it from the ground.
Then I meet Henry with GRB... Wow what a difference dealing with someone that was extremely knowledgeable that explained the process and materials to total satisfaction. He actually walked the roof, took close up photos of the shingles showing that most had zero granules left plus I could see how soft the plywood was while he was walking on it. There's a big… read full review

Wonderful service!!!!! A team member came out the same day I called for what I thought was an attic issue only to find out it was a drywall issue. Even though they realized ahead of time that it was not a job that they would handle, the technician still took the time to look at my attic, answered some of my concerns and referred me to a person that could help with the issue that I have. They were quick, very courteous, and knowledgeable. I am saving them on my “digital roll-a-dex” for when I do need attic repairs.
