I had a really positive experience with AJ and Four Brothers Roofing Co. for a roof tear off and gutters. His team arrived on time, worked fast and efficiently, did excellent work and cleaned up well afterward all for what I would consider a reasonable price. I would definitely recommend this company.

They were very professional and job done quickly as expected. Price was good and did repair any damaged areas with minimal extra cost. Cleaned up all nails and yard immaculate. Well done crew!

Four Brothers recently completed a roof replacement for our house. AJ is tremendous to work with. He is responsive either answering the phone when you call or responding to a text within minutes. Very good at providing details and answering questions. Was also very proactive in helping with a roofing warranty claim. Was quick to resolve any issues we had. Excellent compared to some other contractor experiences we've had. New roof looks great!

We had a great experience working with A.J. and Mike getting our roof and gutters replaced. They were very professional and there we no surprises. The roofing crew also did a great job and cleaned up each night. The job was done in less than two days. Their prices beat all competitors and we had no issues. A.J. was quick to respond to any questions we had. Great customer service. We would recommend 4-Brothers to anyone!!

Installed a patio door and bay window. Also took down a chimney and had to repair roof and gutter after that. They were still over 2k under the price of Pella for just the door and window. The quality was great and they cleaned up the site well before they left. Would definitely use them again.
