Icicles are formed when rooftop snow melts, then refreezes as it attempts to flow off the roof. When that melted snow gets to the eaves and gutters, there is no more warmth coming from underneath, so it freezes. Poor insulation and ventilation leads to more and more snow melting, which is when ice dams can form.
Should I worry about icicles?
There are several risks to knocking icicles down yourself. The first of these is that falling ice can act in unpredictable ways, and in trying to remove it, you run the risk of injuring yourself or others. Another risk is the icicles tearing the entire gutter away from the side of the house.

If the home cannot keep this heat in, the snow on your roof will melt, creating icicles. Poor ventilation is also a culprit for recurring icicles.

How do you prevent ice dams on gutters?

Do gutters cause ice dams?
An ice dam forms when the roof over the attic gets warm enough to melt the underside of the layer of snow on the roof. Gutters at the eaves can also trap snow and ice. If snow and ice build up high enough in the gutter, it can provide a foundation for an ice dam.
How do I remove icicles from my house?
Wear safety goggles and gloves (icicles can hurt), extend the rake from a distance, and gently push the base of the icicles to free them. Then drop some ice-melting tablets (such as Roofmelt, $19; amazon.com) into the gutter to liquefy ice in there.
