  • The Risks of Ignoring Ice Dams on Your Roof

During winter months, homeowners may encounter an unwelcome visitor: ice dams. These formations occur when warmth from the interior of a house melts snow sitting on the roof, only to have the melted snow refreeze at the colder eaves. As this cycle continues, it leads to a buildup of ice that can block melting snow from draining off the roof, resulting in water backup and other issues.

Let’s explore their causes and the risks they pose to understand the critical necessity for the prevention and removal of ice dams.

Common Causes of Ice Dams

  • Outdoor Temperature Fluctuations: Snow melts when temperatures rise during the day. But, as night falls and temperatures drop again, the melted snow refreezes, worsening the problem.
  • Inadequate Insulation: When warm air escapes from the living areas into the attic, it creates uneven melting across the roof.
  • Poor Ventilation: Insufficient airflow can cause warm air to accumulate in the attic, heating the roof surface and leading to further melting.

Problems Caused by Ice Dams

  • Water Damage

When ice dams block the drainage of melted snow, water can infiltrate your home beneath shingles, leading to severe water damage. This situation can compromise ceilings, walls, and insulation. Over time, water intrusion can cause rot in critical structures like your roof, drywall, and flooring.

  • Health Hazards

The presence of water indoors can quickly lead to mold and mildew, particularly in poorly ventilated areas. Mold growth not only wreaks havoc on structural materials but also poses significant health risks, especially for those who suffer from allergies or respiratory conditions.

  • Roof Damage

Ice dams can also have detrimental effects on your roofing system. They can force shingles upward, which may lead to cracks or loose shingles, exposing your home to damaging elements. This kind of wear can reduce the lifespan of your roof and ultimately lead to increased repair costs.

  • Structural Strain

The heavy weight of accumulated ice can place significant strain on both your roof and gutter system. As ice builds up, it can warp gutters or even detach them from the roofline, causing drainage issues and possible damage to the fascia.
