Having delt with snow in Northern Wisconsin -
Lake Superior snow belt for over 50 years
here is some of the things I have found.
The actural depth of the snow is of little
importance, it is the kind of snow that makes
up the depths. Heavy wet snows are more
troublesome than dry powdery snows.
Removing the snow near the edge of a roof
lessens the formation of ice dams and the
rewulting leaks, but the weight of snow nearer
the ridge on non truss roofs is more likely to
crack rafters.
The real danger in deep snow is not the snow
but what happens when the weather warms
up. If or when you get a heavy wet snow or
even worse a rain the snow acts as a sponge
and holds this liquid adding to the weight, this
is what collapses roofs.
I hope this helps you.
