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).

They're a rip off and the owner is completely disrespectful when it comes to speaking with clients. I don't recommend.
