About Us:

At Bay Brothers GC, we’ve been delivering trusted roofing and exterior restoration services across Frederick, Maryland since 2016. Founded by three brothers committed to doing things the right way, we broke away from a system that lacked integrity to build a company grounded in honesty, quality, and community values. From our office in downtown Frederick, we specialize in residential roofing, storm damage repair, and siding replacement, using only top-tier materials and craftsmanship. Our goal is simple: to raise the bar in the roofing industry through reliable service, ethical practices, and long-lasting results. At Bay Brothers GC, every roof we install and every home we restore reflects our promise to protect what matters most.

            Brandon and Dylan were great to work with: diligent, communicative, and overall positive experience. They took care of the insurance, roofing, sidings, and more. Highly recommend! Happy to see almost our entire neighborhood entrusted to them.

            Bay Bros. did a great job replacing the siding and gutters on our home. The material quality was outstanding as was the communication throughout the process. They made sure every detail was completed and very happy with the results. Thank you.

            We had hail damage and needed repairs. Brandon Mazzone worked with us and our insurance company to fix the damage. Brandon was honest with us through the entire process. The work was done promptly and they did a great job. If we had a job-related request or something that needed to be looked at, it was handled quickly and to our satisfaction. Others in our neighborhood used their services and were also happy with their work and in their interactions with Brandon and Dylan.

So much so I decided to have him look at my 30 year old siding. He worked tirelessly with my insurance company since we had many hail storms. He was able to do his magic, really just hard professional work to ensure we could replace our damaged siding. The team was fast, qualified and friendly while installing the siding.
