Customer Reviews

Jordan Mateyka

Bill Tyson and the rest of the GA Castro team were a pleasure to work with. We had our siding replaced, and ran into some snags with rotted wood under our previous siding - Bill and the team communicated with us quickly and addressed the issues prior to putting the new siding up. We love the results, and would definitely recommend GA Castro.

What an amazing job by GA Castro Roofing! From the very beginning, working with Bill Tyson, I knew everything was going to be done right. They made the entire process simple and stress-free, always keeping me informed and answering any questions I had. The quality of their work speaks for itself, and the 50-year warranty gives me great peace of mind knowing my roof is fully covered. I highly recommend GA Castro Roofing to anyone looking for reliable, professional, and top-quality service.
