Ice damning lets the water get under the roofing (more likely in low pitched roofs than a steeper pitch).

It’s the flat or low pitch roofs that are going to take the lake effect snows the worst - they don’t shed the snow easily and the edges by the soffit will freeze up, holding back melting snow behind it - getting it under the roofing and underlayment. If the weight exceeds the total load for the roof, it could collapse, especially as more snow and a warm up is expected into next week (with possible rain).

Snow rakes aren’t exactly useful when you’ve got multiple feet on the roof, but it may still be safer than going up there and trying to shovel it clear.
