We recently replaced a shingled roof, and also coated a metal roof with a previous history of leaking, to prevent future leaks. The shingled roof looks great, and we have had no issues. However, the metal roof started leaking in less than a year. We called Dave, expecting it to be covered under the warranty. He sent someone to look at it, who said that there was an old patch on the roof made of poor quality metal, which had come loose and pulled the coating up with it. Dave claimed that this was not covered in the warranty, because it was the patch that failed and not the coating, and quoted a price close to the cost of the original coating to fix it. He was very rude, and was extremely hard to get a hold of. Ultimately, we found another roofer (Stubbs) who came out, took a look at the problem, and agreed that the old patch was poor quality. However, Stubbs said that the proper solution to prevent leaks would have been to remove the patch when the re-roofing was done, and coat the metal roof underneath the patches, and that most roofers should have known to do this from the beginning. To fix the problem, Stubbs quoted a price that was half of Dave's quote, and promised that any future leaks would be covered under their warranty. We tried to give Dave another chance to explain, but he never returned any of our calls. If you just want a standard shingled roof, Dave's is probably fine, and a cheaper option. However, if you actually want a roofer who will think through potential roofing issues, or quality customer service, I would suggest you look for someone else, like Stubbs, instead.
