What Are Ice Dams?
Understanding ice dams and why they're a problem for homes in cold, snowy climates like McCall, Idaho.
Ice Dams are a common issue for homes in cold, snowy climates like McCall. While they may look harmless at first, they can quickly lead to serious damage if left untreated.
What Is an Ice Dam?
An ice dam is a buildup of ice that forms along the edge of a roof, usually at the gutters. It happens when snow on your roof melts and then refreezes at the colder edges. Over time, this ice builds up and creates a “dam” that prevents water from draining properly.
How Do Ice Dams Form?
Ice dams form through a cycle of melting and refreezing:
- Heat escapes from your home and warms the roof
- Snow on the roof begins to melt
- Melted water flows down toward the edge
- The colder roof edge causes the water to refreeze
- Ice builds up and blocks proper drainage
As this continues, more and more water backs up behind the ice.
Why Ice Dams Are Dangerous
The real problem isn't the ice itself — it's the water trapped behind it. That trapped water can:
- Seep under shingles
- Leak into your home
- Damage ceilings and walls
- Lead to mold growth
- Cause costly structural issues
Ice dams also create large icicles, which are dangerous for people and property below.
Why Steam Is the Safest Removal Method
Steam is the safest and most effective method for removing ice dams because it melts the ice without damaging your roof. Unlike chipping, scraping, or hot pressure washing, low-pressure steam gently breaks down the ice while protecting shingles, gutters, and underlying materials.
This method allows precise removal of problem areas without creating additional damage or loosening roofing components. It's also faster, cleaner, and far less risky — especially on steep or snow-covered roofs. Professional steam removal ensures the job is done safely and correctly the first time.
Homes Most at Risk
Ice dams can happen to almost any home, but they're especially common in:
- Homes with poor attic insulation
- Houses with uneven roof temperatures
- Cabins or vacation homes left unattended
- Areas with heavy snowfall and freezing temperatures
What Should You Do If You Have One?
If you notice ice buildup along your roof edge, or icicles forming behind the fascia or within the soffit, act quickly. Trying to remove ice dams yourself can damage your roof — and it's dangerous without the proper equipment. Professional removal ensures the ice is safely cleared without harming your shingles or gutters.
Preventing Ice Dams
Removal solves the immediate problem, but prevention is the key long-term. Common prevention methods include:
- Improving attic insulation
- Installing heat tape
- Adding snow guards
- Regular roof snow removal
