If you haven’t made consent small talk about the snow lately, you probably don’t live in our market. It’s been a long time since we have seen a winter like this, and although I enjoy the snow, shovelling these large banks is getting tiring. If you’ve ever noticed a thick ridge of ice forming along the edge of your roof, you may be dealing with an ice dam. These formations can cause serious damage to your home if not addressed properly. Let’s break down what ice dams are, why they form, and how you can prevent them from wreaking havoc on your property.
An ice dam is a buildup of ice that forms along the edges of a roof, preventing melting snow from properly draining off. When warm air escapes into the attic, it causes snow on the roof to melt. As the water reaches the colder edges of the roof, it refreezes, creating a barrier. Over time, this dam can trap more water behind it, leading to leaks, structural damage, and even mold growth inside your home.
Signs of Ice Damming
Large icicles hanging from the roofline
Water stains on interior walls or ceilings
Ice buildup in gutters and downspouts
Warped or sagging roof edges
Ice dams might look harmless, but they can lead to significant damage, including:
Roof Leaks: Water pooling behind the ice dam can seep under shingles, leading to costly roof repairs.
Insulation Damage: Once water enters your home, it can soak attic insulation, reducing its effectiveness and increasing energy costs.
Mold and Mildew Growth: Moisture buildup can create the perfect environment for mold, which can pose health risks for your family.
Structural Issues: Repeated ice damming can weaken roofing materials, ceilings, and walls over time.
The good news? Ice dams are preventable! Here are a few key steps you can take:
Improve Attic Insulation & Ventilation: Ensuring your attic stays cold prevents uneven melting of snow on your roof.
Seal Air Leaks: Close any gaps around vents, chimneys, and light fixtures to prevent warm air from escaping into the attic.
Clean Your Gutters: Clogged gutters prevent proper drainage, making ice dams more likely to form.
Use a Roof Rake: After heavy snowfall, carefully remove excess snow from the edges of your roof.
Consider Heat Cables: In problem areas, heated cables can be installed to prevent ice formation.
If you notice an ice dam forming, act quickly:
Use a roof rake to remove excess snow (but do so safely!).
Apply calcium chloride (NOT rock salt) to help melt the ice.
If you’re dealing with leaks or significant buildup, call a professional to assess and fix the issue.
