It can also seep through the walls, the ceiling, and cause structural damage. This causes moisture damage to the roofing, but it also causes water to get inside the attic. Now, that water tends to start going through the shingles of the roof. ![]() A large part of it remains trapped behind the dam, and as the snow keeps melting, it adds to the pool. ![]() When the dams form, the water that remains behind collects in a pool, and some of it freezes, keeping the dam from shrinking. The whole process of ice dam and icicle formation will repeat as long as the temperature is too low and more snow continues to fall. In addition, icicles will start to form at the end of the dam when it starts to melt in the day and then refreeze at night. That water will quickly freeze again and create the aforementioned ice dam at the edge of your roof. You would think that this is a good thing, but if the snow melts more than it should, then the excess water will easily collect in the drains. That causes the roof to heat more than it should and the snow to melt. The most common reasons are poor insulation and lack of good ventilation in the attic.
