News says this snow storm in the NE will bring down roofs

This must be bs, no one in my neighborhood ever shovled their roofs off. They are all like 5/12 pitch hip roofs with 2 x 6 rafters 16" centers.
Mine only has one layer of shingles, my next door neighbor has 3 layers !

How deep of snow will these hold ?? They are all 5 ply plywood decking all built in like 1956

Depends on condition of framing…the wood.

Humm looks fine, no cracks or whatever, I guess if I see my neighbors cave in then I should shovel mine. Doesnt seem like 12" of snow would hurt
