I personally did not use these guys. They were working on our neighbors roof and we went over and asked to get a quote on ours. They said they would be over the next day.
The next day, I wake up and go outside with my one year old son to play in the sandbox. The next thing I hear is one of the guys yelling at another. Except he was yelling obscenities at someone. Who was yelling swear words back at him. It was a constant barrage of "Do you even know what the f$@# you are doing?!" They were using the f-word as if it were going out of style.
And we were going to tell them about it when they came over. But they never came over like they said they would. And they were diagonally across from us, so they were pretty loud with their swearing. But they did eventually start blaring crappy music that at least drowned out the swearing.
