Phenomenal service. A large tree branch fell on our roof and caused damage. I contacted several companies, but Cobalt stood out with their communication and professionalism. Their price was also very fair. They completed the task within the promised timeline and I’m very happy with the quality of their work. I highly recommend them.

Kevin was able to come by right away and give me a quote. He knew his stuff and basically took care of my immediate issue by stopping the leak with a piece of metal flashing. This was even before I committed to anything!

Kevin Callahan of Cobalt Exteriors just finished a roof on my rental property. I couldn’t be more pleased with the service, professionalism, fair price, fast and safe work and genuine kindness of Kevin and his team. I will definitely be recommending Kevin to my friends who need a new roof.
