Since we're still in the storm mode (at least for the time being), you might want to pay attention to those ice dams. Because of the heavy loads, it can potentially damaged your roofs, especially if you live in a Dutch Colonial homes.
An ice dam is a ridge of ice that forms at the edge of a roof and prevents melting snow (water) from draining off the roof. The water that backs up behind the dam can leak into a home and cause damage to walls, ceilings, insulation, and other areas. Figure 1 shows a cross section of a home with an ice dam.

Giant hanging icicles hanging from the eave is an indication of poorly insulated attic with many attic bypasses. So that means, adding insulation in the attic would help remedy this. As a bonus, attic insulation can also help reduce your energy bills.
From Don Lipman, Capital Weather Gang writer (who have lived in Dutch Colonial home for many years), this advice comes handy. "After a storm like the one we just had, the best thing you can do, if at all possible without risking injury, is to remove the snow from the dormers. In general, it's best to limit snow and ice build-up on every roof because, to some extent, they're all vulnerable, particularly the flatter ones and those with more than one layer of shingles."
