Frozen Rain Gutters in MinnesotaOne of the most annoying things about a snowy day, aside from the task of shoveling all the snow from your driveway, are the ice dams that form on your roof’s gutters. It’s almost a given when it’s winter, and although these icicles maybe a simple nuisance and even charming to look at for some, these can pose a real danger not only to you but to your house as well.

Frosty Build-up

What exactly causes these frozen stalactites to form? RTD Ice Dam Removal says it isn’t just the cold weather that can cause them to form on your roof; in fact, the roof itself may be what’s causing these icicles to form.

Ever notice how some roofs only have layers of snow on their roof even when it’s really cold? Generally, this is where all ice dams come from, but they only form if the roof isn’t properly insulated. The lost heat from the roof melts the snow and when it reaches a spot on the roof that’s colder, which is usually around the rain gutter, then the water freezes as it drips, eventually forming an ice dam.

External and Internal Damage

Ice dams, particularly the icy spears at their ends, pose an immediate danger to people. The icicles are surprisingly heavy, and if your roof is a bit higher, it can cause serious bodily harm when it cracks and lands on you. While rare, it is even possible for the frozen stalactite to spear right through you.

The damage ice dams can cause to your house is also considerable. Due to improper installation, leaks may actually form on the roof when the snow melts when it’s just on its way to form an ice dam. This not only weakens the structural integrity of your roof and attic, but it also makes the walls of your home more susceptible to rotting and breaking due to water damage. The weight of the ice dam itself can cause considerable damage to your roof’s gutters, potentially causing it to break in addition to causing blockages.

Getting rid of ice dams before they cause any serious damage or harm is important, but it may be better to enlist the help of a professional, especially for larger and taller houses. You’ll also get professional advice on insulating your attic to prevent ice dams from forming in the first place.
