Worst experience I've had with a roofing company. They fixed a ton of stuff on our roof (as we had leaks) and it didn't even fix the leaks. They're excuse was to blame it on chimney (which we had tested and sealed to close). Everything continued to leak until my husband found the exact spot on the roof where it leaked and sealed it with flex seal. They're a rip off and the owner is completely disrespectful when it comes to speaking with clients. I don't recommend.
