Ice Dam Prevention: What Every Homeowner Needs to Know

What Causes Ice Dams?

Ice dams form when heat escapes from your home and warms the roof, causing snow to melt. The melted snow flows down the roof until it reaches the colder edges, where it refreezes. Over time, this process creates a barrier of ice, trapping additional water and snow behind it. Ice dam formation is commonly caused by:

1.  Inadequate Attic Insulation: Poor insulation allows warm air to escape, heating the roof unevenly.
2. Poor Ventilation: Without proper airflow, heat can build up in the attic and contribute to uneven roof temperatures.
3. Clogged Gutters: Blocked gutters prevent proper drainage, leading to more water buildup.
4. Snow Accumulation: Heavy snowfall creates a thick layer of snow on the roof, which increases the likelihood of melting and refreezing cycles that lead to ice dam formation.
   

How to Prevent Ice Dams

Prevention is the best strategy to avoid the damage and hassle caused by ice dams. Learn more about effective prevention strategies in this National Weather Service article, and explore our practical tips below to keep your roof safe this winter:

1. Improve Attic Insulation: Adding insulation to your attic helps keep warm air inside your home and prevents it from heating the roof. Ensure your attic has sufficient insulation to maintain a consistent temperature.
2. Ensure Proper Ventilation: Adequate ventilation keeps the attic cool by allowing cold air to circulate and warm air to escape. Ridge vents, soffit vents, and gable vents can all improve airflow.
3. Install a Roof Leak Barrier: Leak barriers provide an extra layer of protection beneath your roof’s shingles, safeguarding your home from water intrusion caused by ice dams. Installing a leak barrier is a crucial step in the Eyles roofing process to ensure your home remains protected from potential damage.
4. Clean Your Gutters: Keep your gutters clear of leaves, debris, and ice to ensure proper drainage and prevent melted snow from pooling and refreezing on your roof. Address any necessary gutter repairs or replacements promptly to maintain their effectiveness throughout the winter.
5. Use a Snow Rake: After a heavy snowfall, use a roof-specific snow rake to safely clear snow from the edges of your roof, reducing the risk of melting and refreezing. If the snow buildup becomes overwhelming, consider calling in professionals to handle the job safely and effectively.
6. Seal Air Leaks: Have a roofing professional inspect for gaps and cracks around vents, chimneys, and other areas where warm air could escape. Properly sealing these leaks helps ensure consistent roof temperatures.

What to Do If You Suspect an Ice Dam

If you notice signs of ice dam formation, such as ceiling or wall stains or icicles hanging from the edges of your roof, it’s crucial to act quickly to prevent further damage to your home.
