Ice Dam Prevention Tips for Anchorage Homeowners

What Are Ice Dams?

Ice dams form when heat from your attic melts snow on the roof. The meltwater runs down to the colder eaves and refreezes, creating a dam that traps water behind it. This trapped water can seep under shingles, causing leaks, mold, and structural damage.

Prevention Strategies

1. Proper Attic Insulation

The number one cause of ice dams is inadequate attic insulation. Heat escaping through the roof melts snow unevenly. Ensure your attic has at least R-49 insulation for Alaska's climate.

2. Attic Ventilation

Proper ventilation keeps your attic cold, which prevents snow from melting on the roof. Ridge vents, soffit vents, and gable vents all help maintain consistent temperatures.

3. Clean Gutters

Clogged gutters make ice dams worse by preventing meltwater from draining properly. Keep your gutters clean and flowing freely before winter hits.

4. Roof Snow Removal

After heavy snowfall, consider having snow removed from your roof, especially along the eaves. This eliminates the source material for ice dams.

When to Call a Professional

If you already have ice dams forming, don't try to chip them away yourself. This can damage your shingles. Call AK Gutter Gals for safe, professional ice dam removal and roof snow clearing.
