The short answer

What Ice Dams Do

Ice dams form when heat from your home melts snow on the roof, and the water refreezes at the colder eaves. This creates a barrier that traps water, which can back up under shingles and leak into your attic, walls, and ceilings. The result is often water damage to insulation, drywall, and flooring.

In cold, snowy climates, ice dams are a real concern for homeowners. Heavy snow and freezing temperatures can create the right conditions for them. Acting quickly to remove snow and ice can reduce the risk of water intrusion.

  • Check your attic for proper insulation and ventilation.
  • Remove snow from the roof after heavy storms using a roof rake.
  • Keep gutters and downspouts clear of debris.
  • Seal any gaps or cracks in the attic ceiling.
  • Consider installing heating cables to prevent ice buildup.

Does Insurance Cover Ice Dam Damage

Most standard homeowners policies cover water damage that is sudden and accidental, such as from a burst pipe or a roof leak. Ice dam damage is often treated similarly to a roof leak, so it may be covered if it is not due to neglect or lack of maintenance. However, each policy is different.

Policies vary, and your insurer decides what is covered. Some policies have exclusions for damage caused by freezing, or they may require that you maintain adequate heat in the home. It is important to read your policy and talk to your insurer about what is included.

What Could Void Coverage

While an ice dam alone does not void your policy, certain actions or inactions might lead to a denied claim. For example, if you ignore a known roof leak or fail to make reasonable repairs, the insurer might argue that you did not protect the property. This is different from a sudden event.

Also, if you leave your home unheated during winter and the pipes freeze, that could be considered neglect. To keep your coverage intact, address any maintenance issues promptly and document your efforts. If you are unsure, check your policy or ask your insurer directly.

  • Keep your home heated to a reasonable temperature during winter.
  • Repair damaged roof shingles or flashing before winter.
  • Insulate your attic to reduce heat loss.
  • Ventilate the attic to keep the roof cold.
  • Trim tree branches that could damage the roof.
  • Document any repairs you make for your records.

What to Do After an Ice Dam Forms

If you notice an ice dam, act quickly to prevent water from entering your home. Remove snow from the roof with a roof rake, and use a de-icing product to melt the ice. Do not use a hammer or chisel, as that can damage the roof. Once the dam is gone, check your attic for any water stains or damp insulation.

If water has already leaked in, you need to dry the area thoroughly to prevent mold and structural damage. Use fans and dehumidifiers to dry out walls and floors. For significant water damage, you may need professional help to extract water and dry the structure properly.

When to Call the Pros

If the ice dam has led to water intrusion, you might need help from local water damage pros. They can assess the extent of the damage, extract standing water, and set up structural drying and dehumidification. This can help prevent mold and further damage to your home.

The pros can also help with leak detection to find hidden moisture and with drywall or flooring repair after the area is dry. Do not wait, as delays can lead to more damage. If you live in Columbus, you can find local water damage pros to assist with the cleanup.

Can I prevent ice dams without professional help?

Yes, you can take steps like improving attic insulation, using a roof rake to remove snow, and keeping gutters clean. These actions reduce the chance of ice dams forming. For severe cases, you might need a professional to install heating cables.
