Tim B. Verified Bay 101 Roofing, Inc. Customer Name
Q1:10 out of 10
Q2:Yes
Q3 & Q4:"I would give them a '10+'. First of all, I got to talk to someone who could make a decision. My initial contact was with the owner. Both he and the foreman were very easy to deal with and talk to. If they said they would do something, they did it. It was a real revelation for me as far as roofers. Contrary to previous experiences, my experience with Bay 101 was very positive. Everything was completed as promised. The crew that came out the second day was the same as the first day. This was so good, because they knew what was going on. The crew was very helpful. If they were doing something, and I wasn't happy with it, they would stop and we would talk. Then, they would do it the way I asked. I was also doing some work on the exterior of the house at that time. They were very helpful in accommodating what I was doing and not getting in the way. There was a problem with the way the gutters were on the house, so they hosed the roof down and checked to see how the water drained. One of the sides of the patio didn't drain, but they said the solution was to put in another downspout. I instructed them to do it a certain way, but it didn't get done that way. They came back and corrected it, no hassle. They didn't try to "nickel and dime" me. That continued to make me think of this as one of the best experiences I have had. It was the most pleasant remodeling experience I have ever had, by far. They have really earned Diamond Certified. They did everything I asked and more."

Q3 & Q4:"He was very professional. He explained everything. He just let us make up our own minds. He was a very nice person and so were his workers. Whatever we wanted, they did. We felt very confident going with their company. We went with him because when he started talking, just by listening, we could tell he knew what he was doing."

The workmen were very good and they did the whole thing in less than three days. This meant tearing off the old roof and putting on the new composition roof. I was impressed with the clean-up as well as the price. Some bids were $5,000 more than theirs. Not only did they give me a low bid, but they did a terrific job. I have the Diamond Certified book here at home and I use it. I believe they certainly warrant being Diamond Certified."

The crew was very nice as well. My roof has a solar heater on it, and they managed to work around it. They cleaned up after themselves and made sure my pool was covered when they tore off the roof."
