Moreover, are Icicles a sign of poor insulation?

That means there's heat loss likely due to poor insulation and/or ventilation in the attic. Also keep an eye out for icicles — another sign of heat loss. If your roof is warm enough to melt the snow but it's cold enough outside for snow to refreeze, your roof is losing heat.

Furthermore, do icicles cause ice dams? Icicles don't always mean ice dams. But they do mean snow is melting on your roof, and that some of the runoff is freezing into icicles as it trickles off the edge of your roof. It's this very “melting-and-refreezing” process that causes ice dams in the first place.

Herein, does removing icicles help ice dams?

The icicles and ice dam add weight to your gutters that could tear the gutters from the house, causing significant damage. The ice can also get under your shingles and begin to leak inside your home, causing water damage. Don't try using a hammer or rake to knock large icicles off your gutters or remove ice dams.
