How Ice Dams Form and How to Protect Your Roof from Them in Merton
Merton's Reliable Roofing Professionals
Winters in Merton can be beautiful, with snow-covered trees and cozy nights by the fire. But for your roof, the season is anything but peaceful. One of the biggest threats to Wisconsin homes in the winter is something many homeowners don’t see coming. We're talking about ice dams. They might look harmless from the ground, but once they start forming on your Merton roof, they can cause serious damage.
However, with the right knowledge and a little prevention, you can avoid the stress and expense that ice dams often bring. At Hucke Exteriors, we’ve seen the damage firsthand and we’re here to help you protect your home.
All You Need to Know About Ice Dams in Merton
What Is an Ice Dam?
An ice dam is a ridge of ice that forms at the edge of your roof, usually right along the gutters. It forms when snow on the upper parts of your roof melts from attic heat and then refreezes when it reaches the colder roof edges. As more snow melts and refreezes, the ice dam grows. Eventually, this blocks the path of melting water, which then backs up behind the dam and can seep under your shingles.
Once water gets past your roof’s outer layer, it can leak into your attic, walls, and ceilings. That can lead to stained drywall, warped wood, mold growth, and even structural damage.

Why Ice Dams Happen in Merton
Ice dams are common in colder climates like ours, especially when homes have uneven roof temperatures. A few things can make your home more prone to ice damming:
- Warm attics: When your attic isn’t properly insulated, warm air escapes and heats up the roof from underneath, starting the melt-freeze cycle.
- Poor ventilation: Without proper airflow in the attic, heat builds up and raises the temperature of the roof deck.
- Clogged gutters: If your gutters are full of leaves or ice, they can trap melting snow, allowing it to freeze at the edge and build up into a dam.
- Heavy snowfall: After a big storm, snow can build up quickly, especially on roofs with shallow slopes or multiple valleys where snow naturally piles up.
How Ice Dams Damage Your Home
Ice dams may start on your roof, but the damage doesn't stop there. As water backs up behind the dam, it can seep under shingles and into your home. This can lead to:
- Leaks in your attic or ceiling
- Mold and mildew growth
- Damaged insulation
- Warped wood and sagging drywall
- Weakened roof decking
Even a small ice dam can cause expensive repairs if left untreated.
How to Prevent Ice Dams Before They Start
Prevention is the best approach to protecting your home. Here are some simple, effective strategies:
- Improve Attic Insulation and Ventilation: A cold roof is a healthy roof in winter. By keeping warm air inside your living space, you prevent uneven roof temperatures that trigger melting and refreezing. Have your attic insulation evaluated, and consider installing ridge or soffit vents to improve airflow.
- Clean Your Gutters Before Snowfall: Gutters filled with debris can’t drain melting snow properly. Clear them out in the fall and check them again after storms to ensure water can flow freely.
- Use a Roof Rake After Heavy Snow: A roof rake with an extended handle lets you safely remove snow from the lower edge of your roof without climbing up. This reduces the chance of snow melting and refreezing at the eaves.
- Consider Heat Cables: Heat cables can be installed along the roof’s edge or inside gutters to keep these areas above freezing. They provide a steady defense against ice formation, especially in problem spots.
- Install Ice and Water Shield: If you're replacing your roof or upgrading key areas, ask about ice and water shield. This waterproof barrier goes beneath your shingles and helps prevent leaks if ice dams form above.

What to Do If an Ice Dam Has Already Formed
If you spot a ridge of ice on your roof or notice water stains on your ceiling, don’t panic. Don’t try to chip away at the ice either because it could damage your roof.
Here’s what you can do instead:
- Use a roof rake to remove fresh snow from the area
- Place a calcium chloride-filled sock or tube on the ice to melt channels through it
- Never use rock salt. It can ruin shingles and corrode gutters
- Place towels or buckets inside to catch drips if leaks occur
Most importantly, address the problem early to minimize damage.
