I had a roof leak that another company tried three times to fix. BCI recognized the issue and went above and beyond in getting the repair done before winter and making absolutely sure that everything was repaired properly. Highly recommend.

BCI (and my main contact Taylor) were great to work with. Ive done extensive remodeling on my home and have always had challenges. Short of a couple small communication issues, this experience was pretty flawless and we are very happy with the end product so far. BCIs pricing was very competitive and numerous neighbors commented to me about their quick work and quality appearance. We had our entire roof and all gutters, downspouts, etc, replaced. I would highly recommend them. On-site crew was also very nice and did their best to minimize the mess left (impossible to eliminate mess from a
