C3 replaced our roof yesterday, and we are very happy! I had called a few months before about a siding issue, and was very impressed when Colby told me that we didn’t actually need new siding, just an inexpensive repair, and then he did a quick, temporary fix for free.

C3 is a 5 star roofer. Our 3500 sq. ft. roof was installed in 2 days which included the replacement of numerous wood panels. The crew was professional, timely, and cleaned up afterwords.

I was very impressed with Mason and C3 American from the very first visit. Their bid was much lower than the other businesses I met with, so I was a bit skeptical.
