NASHVILLE — With recent temperature fluctuations, AAA is alerting Tennessee homeowners about the potential for ice dams, which can damage roofs and the interior of homes. The organization is sharing tips on how to identify and address ice dams and when to involve insurance providers.

“Ice dams are more common in northern states, but they can form anywhere with drastic temperature shifts,” said Megan Cooper, spokesperson for AAA – The Auto Club Group. “Recognizing the signs early can save homeowners from costly repairs to attics, walls, ceilings, insulation, and floors.”

How to Spot Ice Dams

• Look for icicles forming along the edges of your roof or gutters.
• Ice may accumulate along roof overhangs, or gutters may be filled with ice.

How Ice Dams Form

Ice dams develop when heat escapes from inside the home, warming the attic and melting snow on the roof. The melted snow then refreezes as it reaches colder eaves, creating a buildup of ice. As more snow melts and refreezes, ice can push under shingles, allowing water to penetrate the roof and seep into the home.

“Once water enters your home, it can cause peeling paint, warped floors, and soggy insulation,” Cooper added. “Left untreated, mold and mildew could develop. Ice dams may also loosen shingles, rot wood, or tear off gutters.”

What to Do if You Have Ice Dams

1. Don’t panic.
2. Call a professional. Attempting to remove ice dams yourself can cause further damage or injury. Hire a licensed contractor experienced in ice dam removal to assess and repair any damage.

“If you notice water damage or leaks, contact your insurance provider immediately to review your coverage and file a claim,” said Cooper. “Many policies cover ice dam damage, but exclusions may apply.”

Even without damage, homeowners are encouraged to review their coverage to ensure they’re prepared for potential weather-related issues.

Preventing Ice Dams

To prevent ice dams, homeowners should focus on keeping the roof temperature consistent with the eaves:

• Increase attic ventilation with soffit, gable, and ridge vents to circulate air.
• Check attic insulation depth and ensure it isn’t blocking vents.
• Seal attic ducts and insulate exhaust fans that lead outdoors.

For homes with living spaces in the attic or more complex issues, consult a professional for ventilation or insulation upgrades.

While clearing snow from roof edges and gutters can help, AAA advises against climbing on roofs to remove ice dams. “The safer and more effective solution is to address insulation and ventilation issues,” said Cooper.

For major ice dams, hire professionals who use safe removal methods to avoid damaging shingles.

Be Prepared

AAA encourages Tennessee residents to be proactive in addressing ice dam risks. “Understanding prevention and repair options now can save significant time, money, and stress later,” Cooper concluded.
