As I just posted in another thread, when it gets to be over a foot of snow on the roof, I worry. Was expecting our 4th storm in 3 weeks and decided to clear some of it off. Had close to 2 feet. Top layer was light and fluffy but the older snow had compressed and begun to freeze. Didn't get on the roof, used a plastic shovel and did it from a ladder. Was a lot of work, especially at night and in frigid temps. Will do this whenever I am not comfortable with what I see, no matter what Jayco says.
