I will start with what is good about this roofer. They were super fast. Started the job immediately and each phase was right on time (except for the delay that I elaborate on below). Workers had integrity and much skill. The end result is beautiful, a quality job for sure. The billing process was pretty clear, they charge you to use a credit card, which I get and do not resent. Another positive is their frequent and quick communication. The cost was the same as our other bid, so I guess it was ok, but $25,000 was a hard bill* to swallow. The project manager, salesperson was very slick with his presentation which made me a little wary. He gave off an arrogant vibe that I guess is typical for a sales rep. So I would not say that it was a negative per se. At the end of the job, they had not cleaned up the last bit of material from our driveway and an item was left on the roof. I said that I would hold the last check until that got cleaned up. He said, What, you don't trust me? Well, no And, as typical for the company, they did clean it up quickly, some poor folk in a van that had to shove a bunch of material into the back forcing the workers to sit on each other lap. Ugh. So that was resolved quickly, though we have found about 12 nails on the driveway in the last month or so. No punctured tires - yay. My husband was a contractor and knows some things but is not perfect. For example, he did not think that the roof needed replacing, but the insurance company and 2 roofers said that it was in need of replacement. But, when it came to the roofers halting the job after removal of the shingles to say that the plywood needed replacing to the tune of $10,000 (with a senior discount - ugh), my husband was correct. The plywood was slightly bent in some areas, there was no water damage and no indication that the bent plywood would cause the new roof to somehow fail. The upsellers from the company claimed that the bends in the roof caused by the less than perfectly smooth plywood could cause the roof to fail. In this case, they said, they would not honor their warranty. BUT, the warranty was never at risk, really. That is guaranteed by the shingle manufacturer who stands by the installation even if the roofer goes out of business. If the job installation was really in danger of failing before the 50 years was out, I reason, the manufacturer would not stand by the installation of the roof without the new oriented strand board that they were pushing. Talking to other contractors, my husband's assessment of the need for new plywood was corroborated. In the end the upsellers said that it was our decision. When I called to say that we did NOT want new plywood, they had no issue and finished the job so very fast. If, indeed, the slight warping in the plywood WAS a problem, I would have expected them to say, well, we cannot finish the job, the roof will not stand up to the elements, the warranty would not be honored, etc., but they did not say that. In short, this upselling of two layers of oriented strand board seemed to be a scam. One claim that the upsellers from the company promoted was that the knots in the old plywood might pop out. Anyone who knows how plywood is made will tell you that a knot may be present and problematic on ONE layer of the plywood, but the knots do NOT weaken plywood because there are many other knot-free layers underneath causing it to be super strong despite the one knot. This is true especially with the plywood on our roof which had never seen any water damage. My husband also said that there are other ways, if needed, to fix slight problematic warps which do NOT require the replacement of the entire roof plywood as they were proposing. Thankfully my husband made it so that we did not fall for this scam. I would recommend this roofer to someone who wants to get their job done QUICKLY and well, who has a healthy d...
