Some advice. Look the roof over after they are done and if you see lines/streaks marks on the vinyl make them fix it on the spot. I was told they will go away on their own and its been months now and they are still there on the car. Some did go away from the sun's heat but not all.
Better yet tell them that upfront so they know you aren't going to accept it.
