Wisconsin winters are beautiful, but they’re also tough—especially on your roof. One of the most common winter roofing problems we see at Schabel Exteriors is the formation of ice dams. These thick ridges of ice along the eaves may look harmless, but they can cause serious and expensive damage if ignored.
What Exactly Is An Ice Dam?
An ice dam is a buildup of ice that forms along the lower edge of your roof, usually at the eaves. As snow melts higher up on the roof and flows downward, it refreezes when it hits the colder edges. Over time, this creates a ridge of ice that traps melting snow behind it.
When water can’t drain properly, it backs up under shingles, seeps into the roof deck, and makes its way into your home.
What Causes Ice Dams in Wisconsin?
Ice dams happen in cold climates everywhere, but Wisconsin’s temperature swings and heavy snowfalls make them especially common. They’re typically caused by a combination of:
- Warm Air Leaking Into the Attic
Heat from your home escapes into the attic, warming the roof surface and melting snow.
- Poor Attic Insulation
Insufficient insulation allows indoor heat to reach the roof, accelerating melt-and-freeze cycles.
- Inadequate Ventilation
Without proper airflow, warm air gets trapped in the attic and heats the roof unevenly.
- Heavy Snow Accumulation
More snow = more melting and refreezing.
If your attic is warm but your eaves remain cold, that’s the perfect recipe for an ice dam.
How Ice Dams Can Damage Your Home
Left unchecked, ice dams can cause:
- Shingle damage
- Roof leaks
- Rotted roof decking and framing
- Mold and mildew inside walls or ceilings
- Gutter damage or collapse
- Insulation deterioration
Even a small ice dam can result in thousands of dollars in repairs if water begins seeping into your home.
Early Warning Signs of Ice Dams
Here’s what Wisconsin homeowners should watch for:
- Icicles hanging from the roof edge
- Ice forming behind gutters
- Water stains on ceilings or walls
- Condensation or frost in the attic
- Uneven melting on the roof
If you see these signs, it’s time to act before the problem escalates.
How To Prevent Ice Dams
At Schabel Exteriors, we specialize in long-term solutions that protect your roof through even the harshest Wisconsin winters.
- Improve Attic Insulation
Upgrading insulation helps keep warm air inside your home—exactly where it belongs.
- Increase Attic Ventilation
Proper soffit and ridge ventilation regulate attic temperature and reduce uneven roof heating.
- 3. Safely Remove Excess Snow
Roof raking or steam removal can sometimes stop an ice dam early, but it’s best to consult a certified roofing contractor since improper use can damage shingles.
- 4. Install Ice & Water Shield
This leak barrier membrane provides added protection in vulnerable areas like eaves and valleys—especially important in Wisconsin.
