I recently had a complete tear down for my roof (I live in the east bay). The customer service was excellent in my experience. Everyone was friendly, responded quickly to my phonecalls/emails etc. I had five (5) bids for my house and they came in near the middle ground. In fact, they added custom chimney flashing and finishing work to the scope at no additional charge. The workmanship was second to none, the same guys came to the house each day and did an excellent job. It has been over a month and I haven't seen anything rip at the seams, but with the long warranty on workmanship I am not that worried. I would recommend using them again for any/all roofing needs.
