“Needing a new roof, I put the job out for bid. The Colbalt Exteriors company was selected to do the job. I found the company professional not only the leadership, but the crew also. The cost was reasonable and fair. and most importantly the quality of the work was outstanding. Working with Kevin and Corbin was a pleasure.”

“Communication is huge for me. They were great from start to finish. There were some delays due to products being delayed, Covid blah blah blah, but they were sure to keep me informed along the way. I change my mind about a design mid project and they had no problem re-doing it for me. Oops! Super friendly staff and owners. I highly recommend!”
