Expert Advice from Eaton & Berube Insurance
Ice dams are a common winter hazard in New England, and with claims on the rise, it’s important to know how to protect your property. At Eaton & Berube Insurance, we’re committed to helping you stay informed and safe through every season.
What Are Ice Dams?
An ice dam is a ridge of ice that forms along the edge of a roof, typically after a snowfall and subsequent freezing temperatures. When warm air escapes from your home into the attic, it melts the snow on your roof. The melted water travels down the roof and refreezes at the colder eaves, creating a dam. Over time, more melting and refreezing causes the dam to grow, trapping water behind it. This water can seep under shingles and into your home, leading to damage.
Why Does this Matter?
Ice dams aren’t just a winter nuisance—they can cause significant property damage. Water leaking into your home may ruin insulation, stain ceilings and walls, and even promote mold growth. In severe cases, structural damage can occur, compromising the integrity of your roof and the comfort of your living space. For homeowners and business owners, the financial impact can be substantial, especially if repairs are delayed.
Key Causes of Ice Dams
- Poor Attic Insulation: Insufficient or uneven insulation allows heat to escape, warming the roof and melting snow.
- Inadequate Ventilation: Without proper airflow, attic temperatures rise, contributing to snow melt and ice dam formation.
- Clogged Gutters: Debris-filled gutters prevent melted snow from draining, increasing the risk of ice buildup.
- Unsealed Attic Bypasses: Gaps around pipes, wiring, and chimneys allow warm air to escape.
Warning Signs to Watch For
- Icicles hanging along the roof’s edge or gutters
- Water stains or moisture on interior ceilings and walls
- Peeling paint near the roofline
- Mold growth or musty odors in the attic
- Unusual drafts or cold spots in your home
Preventative Measures: Protect Your Property
- Improve Insulation: Make sure your attic is properly insulated to keep warm air inside your living space and out of the attic. This helps maintain a consistent roof temperature and prevents snow from melting prematurely.
- Enhance Ventilation: Install soffit and ridge vents to promote airflow, keeping the attic cool and minimizing snow melt.
- Seal Air Leaks: Inspect and seal gaps around light fixtures, pipes, and chimneys. This reduces heat transfer and lowers the risk of ice dams.
- Clear Gutters: Regularly clean gutters and downspouts to ensure proper drainage. Consider installing gutter guards to prevent debris buildup.
- Remove Snow Safely: Use a roof rake to gently remove snow from the roof’s edge after storms. Never climb on a slippery roof; hire professionals if needed.
- Schedule Professional Inspections: Have your roof, attic, and insulation checked annually by qualified contractors to identify and address potential problems.
What to Do If You Spot an Ice Dam
If you notice signs of ice damming, act quickly to minimize damage. Remove snow from the roof’s edge and place containers to catch any water inside. Don’t attempt to chip away the ice yourself, as this can damage shingles and create safety hazards. Reach out to a professional for safe removal and repairs.
