"Polite, respectful, friendly, honest, competent, detail-oriented, committed to customer satisfaction, going the extra mile, quality product and workmanship, reasonable price. John and his team replaced my worn and leaking gutters with new 6” gutters, new downspouts, and installed gutter guards. While I didn’t expect it or ask, they repaired cracked cement and left the place looking clean and great."

"I reached out to champion and five other companies for an estimate on a new roof. While their estimate was neither the highest or lowest, it was acceptable, but it was the caring of the owner to answer my questions/concerns and make sure I understood everything that was appreciated. Their team worked hard the two days prior to Thanksgiving doing everything to not just make my roof look good, but be safe and last. When finished, everything was cleaned and put back where it was prior to the work starting. They came back to replace my gutters as well and again did a spectacular job. My home is old and the last roof/gutter work was over 30 years ago. There were some unexpected issues that can happen with an old home, but they were happy to work with me to get as much taken care of correctly as we could. I highly recommend them."

"Zach and team replaced my roof, gutters, installed gutter screens, and replaced rotted wood molding. They were professional and kept me informed on the progress of the job with pictures from their drone. They were not the cheapest but based on the excellent work they did repairing siding after a storm a couple of years ago, I selected them to do my roof. I may have them build me a new deck and repair my retaining wall in the future."
