From the very first encounter (with the estimator), it was a very good experience. The estimator listened to my needs and concerns. He spent 45 minutes with me explaining the methods, materials, and design of the proposed roof. He warned me that some dust & grit would unavoidably come through the ceiling (I don't have an attic, and the wood plank ceiling is right under the roof). That gave me the opportunity to cover my furniture, etc. with sheets & tarps and minimized cleanup for me. The work was done in 3 days, and the crew cleaned up very well each day. It hasn't been a hot summer, but the energy efficiency of the roof has definitely helped keep my house noticeably cooler. I got 2 other estimates before choosing Berkeley Roof Services (BRS). The first had a very nice & helpful estimator, but the roof he proposed had a lower level of energy efficiency than I wanted. That bid was proportionately less than BRS's. The third estimate I got was for the exact same thing as BRS proposed, but $2,000 more expensive. Plus, I thought the estimator was a jerk. He didn't listen to me, talked about himself a lot, and seemed disdainful of some of the questions I asked. The ONLY negative with BRS had to do with the foreman of the roofing crew. He was nice to deal with, obviously knew what he was doing, and the job was done very punctually. However, the first day of the job I was supposed to wait for him to go over the particulars. He was more than an hour and a half late, and he didn't call to let me know. I called BRS after waiting an hour, and when he called back he said he was about 45 minutes away. I should NOT have had to call him, he should have called me to let me know. After the bulk of the job was completed, there was a very small area on the siding that needed to be painted to cover some putty. It was probably about a 15 minute job. I provided the needed paint. It took weeks, with me calling twice to find out when he would be there, to get it done. The touch-up was completed, though, and I was happy with the result. This aspect of the job was the only less than wonderful part of the project and would not make me hesitate to work with BRS again. Considering the exceptional work and the rest of the experience, however, Berkeley Roof Services was GREAT. I've recommended them to 3 friends and a friend of a friend. I wouldn't have done that if I hadn't had a fantastic experience with BRS.
