My experience with Bay 101 Roofing was frustrating. I went with Bay 101 over a more local company (charging thousands less) because I thought I was getting quality service and because Dave, one of their sales guys, told me they were good employers, offering their roofers workers compensation and other benefits (rather than picking up short-term laborers). The roofing and gutter jobs were fine, but there were headaches one never expects when paying tens of thousands of dollars for a job: 1) There was no Honey Bucket which means the area of my house behind the chimney was wet and smelled of urine; 2) Tar from the tear-off fused onto our brand-new garage door (Dave sent a worker over to work on getting it off after I called); 3) I still find it unbelievable that despite promises, no one from the company showed up for the city inspection! (This really blew my mind. As a result, they left a 16 ft. extension ladder and never came back to get it.); 4) Six months later I discovered that our attic was a disaster from the tear-off, but no one mentioned anything to me about this possibility and they didn't make any move on their part to prevent it. (I bring this up because I just had an AT&T installer up there and he commented about the mess); 5) The worst part was trying to get my manufacturer's warranty for the shingle product. Five months after the install I received an email from Dave promising me that they were going to have the warranty sent soon, but 2 of their computers had "melted down" from viruses. I forgot about it and when I remembered 2 years later, I contacted Lorena. What I thought would be a friendly, "Oh, let's help get that for you since we've completely dropped the ball for 2 years" response was in reality Lorena lying to me -- telling me that I had no shingle warranty. I'm not sure what was in it for her to lie to me other than to cover-up their failing and not have me follow-up on it. My interaction with her wasn't angry because I was too dumbfounded at her response. In the end, I had to forward Dave the email he'd sent me about the viruses/warranty to prove my point and get them to act. And when I finally did get the shingle warranty, I discovered that since they'd failed to register in a timely manner, the best they could do was register it... for a date TWO YEARS after they'd done the roof. When I contacted Dave to see if he could set it straight, they had the manufacturer's rep. call me to say, "don't worry, man." One thing I do know: if my 40 year shingles fall apart in 20, the manufacturer is going to look for an excuse to not honor the warranty. And, thanks to Bay 101's debacle, they'll have one. Pros: Dave Imhof is a nice guy. He quoted the job factoring in things we specifically knew his workers would find during the tear-off (rotten rafter tails and fascia), rather than surprise me with a larger bill after they were done. Cons: Follow-through! How can anyone brag about being Diamond Certified and charging more when they can't deliver what I've paid for. Facts are facts: when I paid the bill, I paid for the work, shingles, gutters, warranty. The follow-through required to deliver all of it is not optional! Staring at a very confused city inspector asking me what he should do about the sign-off and ladder placement (what luck that I work from home and was here when he showed up) is not a pleasant experience. Also, I mentioned to Dave that we wanted a couple of Sun Tunnels installed before the new roof was on. Dave referred me to G.T. Builders (not on Angie's List, and now I know why). My experience with him was horrible. I felt very fortunate that when he left the only damage I was left to fix was an unpainted patch in my ceiling where he sawed into an area he hadn't checked out (that would not fit the sun tunnel) and a giant oil slick in the middle of my driveway from his broken truck. All in all a bad experience. If you do go with them don't pay the balance until you are 100% satisfied or -- from my experience -- they are not likely to follow-through.
