What Are Ice Dams?

Ice dams are ridges or sections of ice that form at the edge of a roof and prevent melting snow from draining off. They typically occur when the upper areas of a roof are above freezing temperature, causing snow to melt, while the lower edges are below freezing, causing the water to refreeze. This cycle creates a dam of ice, trapping water on the roof.

How Do Ice Dams Cause Damage?

The trapped water can seep under shingles and into your home, leading to several problems:

  • Water Damage: The most immediate issue is water leaking into your attic, walls, and ceilings, causing damage to insulation, drywall, and even creating a breeding ground for mold.
  • Structural Damage: Over time, the weight of the ice dam and trapped water can strain your roof, potentially leading to structural damage.
  • Gutter Damage: Ice dams can also cause damage to gutters and downspouts, as the weight of the ice can pull them away from the house.

Preventing Ice Dams

Preventing ice dams is key to protecting your roof and home:

  1. Proper Insulation: Ensure your attic is well insulated to minimize the amount of heat rising to the roof.
  2. Ventilation: Maintaining consistent attic ventilation helps regulate roof temperatures, thereby diminishing the likelihood of ice dam development.
  3. Remove Snow from the Roof: Carefully removing snow from your roof after a storm can prevent ice dams from forming. It’s advisable to hire professionals for this task to avoid damage to your roof and for personal safety.
  4. Seal Attic Bypasses: Warm air leaking into the attic from the house can contribute to uneven roof temperatures. Sealing these bypasses can help prevent ice dams.

What to Do If You Have Ice Dams

If you notice an ice dam forming on your roof, it’s important to address it promptly:

  • Call a Professional: For safe and effective removal, it’s best to call a roofing professional experienced in dealing with ice dams.

Understanding what ice dams are and how to prevent them is crucial for homeowners in Oregon, especially following severe winter weather. By taking proactive steps and seeking professional help when needed, you can protect your home from the potential damage caused by ice dams.
