Check for ice dams, loose shingles, and deep snow loads, but winter snow alone usually isn’t damaging; roofs are built to handle typical loads.
In fact, it acts as an insulator that protects the shingles. And, even when it's deep, the snow's weight is less than what the roof is designed to bear; the average roof is built to carry loads of 65 pounds per square foot. Even flat roofs, which seem more vulnerable to snow loads than pitched ones, are pretty tough. In fact, residential flat roofing is stronger than commercial roofs.
