Simply so, why do I have so many icicles on my gutters?
The cause of ice damming is very simple: too much heat in the attic. If the temperature in the attic is above freezing and there is snow on the roof, the snow melts. Since the gutter is not above the house where it can be heated, the water refreezes into ice – presto – ice dams in the gutter and icicles hanging down.
Beside above, 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.
Considering this, should you remove icicles from gutters?
Proper removal of icicles from a gutter should be done from the roof of your house. There are risks involved with working on your roof, especially in icy conditions. Our roofing experts are used to these risks and can not only remove existing icicles but prevent them from forming in the future.
What can I do about large icicles?
The most effective way to eliminate ice dams is to stop snowmelt by making the roof colder. This can be achieved by insulating the floor of the attic and under the roof, and by blocking all crevices where warm air from the interior can rise into the attic. If possible, keep snow off the roof with a snow rake.
