"A happy returned customer! I had Alpha One for a couple of patch jobs before and was impressed with their approach back then. They listened attentively, explained clearly, and did not push to sell and instead delivered what I wanted for the moment. I called them back again last month for a quote to replace the roof. They did not give the lowest bid, mind you, but they were painstakingly detail oriented, transparent, and had everything written down black and white without any gray area. Mike, who managed my project throughout to process, was simply Amazing. He was responsive and answered all my big small random questions with patience and grace. The whole crew was terrific too!! Now I can't wait for it to rain lol, while appreciating my brand new roof!"
