Very flat roofs should at least be cause for concern but the normal northeast pitched roofs are just fine. I prefer to have that snow on my roof as it is great free insulation. And as has been addressed prior in this thread, another big misinformation by the media is after big snowfall they love to tell you that the warm temps will be adding weight so get that snow off now. Rain, of course is a different story but for those with flatter roofs, be happy if warm weather follows because any melting will lighten the load.

I agree. For the most part, I think you are likely to cause damage to a roof by shoveling it. Not only by hitting it with the shovel or anything else, but by possible damaging the shingles by walking on them when they are cold and brittle.
Of course there are exceptions...flat or near flat roofs built before current standards could be cause for concern. Otherwise, like Siksukr said, take advantage of the extra insulating value of the snow cover.
