Just had third roofing by Chouinard and would not consider any other roofer. This time I asked for a quote and Chevy discovered a major hole caused by raccoons on the far side not seen from front of house. They came the next day to repair and patch, then completed the entire roof promptly.
As the raccoons again attacked, Chouinard replaced the plastic vents with metal ones free, and that seems to have worked. However, another attack at the bottom edge meant recommendation to install metal edge all around, and this again was completed promptly.
Highest recommendation for work, communication and prompt attention.
