We had our roof (replace decking/new shingles) done by Eurotech couple of years ago. The sales pitch was great and convincing, the price was on the high side but we went with them anyway. I really wish, the installers were half as competent as the sales guy ! The work felt shoddily done and has been a nightmare with them since. They left nails and plywood chips/pieces all over the fiber glass insulation in the attic. When questioned, they said it was not their responsibility to leave the attic clean it was very clean when they started and now its unsafe to climb up there. Multiple areas of siding/gutters and downspouts were damaged. Since they were not hired for gutters, they were not responsible ! First rain and the skylight (they installed new with the decking/shingles) started leaking, the guy comes over after dozen calls, makes us buy a new one, installs it with loads of caulk. We had the walls/paint inside fixed separately. Days later we started seeing wet spots on the ceiling, more calls and the guy comes back with caulk gun, says it was just a bad nail More wet spots show up in the winter, looked up in the attic, the nails are rusted and there is mold. 2 months of calls and no resolution. Anytime you call them, they say they are working on it. Climbed up the roof in spring and noticed that the decking is warped in multiple locations and shingles are curved. The deck/plywood has gaps where you can see through the shingles. Despite all this, and one of their own guys stating this was terribly wrong, I can't have them come up with a resolution. In 2 months, I've talked to Cresta/Drew/Tim/Jared more than once, with some up to dozen times. In this time, we got multiple calls from them for more business but no word on this issue. I cannot comment on their other workmanship, but for roofing they are a complete waste of time/money. For following through when things go bad, this company cant be trusted. (you cannot give zero stars here!)
