How to Prevent and Deal with Ice Dams

Many people think that the icy wall slowly forming along the edge of their roofline during winter is harmless and picturesque. What you might not know is that these formations, called ice dams, can collect water that backs up underneath shingles and seeps into homes. By the time you notice the damage, you'll need extensive repair work at the worst possible time of year, at a cost that may bust your budget.

When you learn how to prevent and deal with ice dams correctly, you can erase your worries about this common source of winter water damage. 

How to Prevent Ice Dams from Forming on Your Home

1. Make sure you have adequate attic insulation.

Check to be sure that your attic insulation provides the minimum R-value your local building codes require. Make sure the insulation forms a complete blanket across your attic floor, without gaps.

2. Close up areas of heat exchange from the main floor.

Heat loss from your living space rises into your attic, which triggers ice dam formation.

Seal any air leaks from gaps in drywall, light fixtures, plumbing, electrical wiring, chimneys, and even the attic access door. Exhaust fans must vent to the home's exterior and not into the attic space.

3. Unblock or add attic and roof vents.

If your attic feels warm, you must increase airflow between the outside and your attic.

Add more vents to the roof and eaves if necessary. Ensure storage containers or leaf debris never block vents.

How to Deal with Ice Dams that Form on Your Home

Getting rid of ice dams after they establish can be tricky business. Working in cold weather with ladders, rakes, de-icers, or heat cabling can be dangerous. If possible, hire a company that specializes in ice dam removal. Call a professional remediation service to deal with any water leak damage, and provide ways to stop future ice dams from forming before they ruin your holiday season.
