Ice Damming Isn’t Just an Eyesore, It’s a Serious Threat to Your Home

Those thick ridges of ice hanging off your roof might look like a normal part of winter, but ice damming is one of the most common (and costly) cold-weather issues homeowners face.

If left unchecked, ice dams can quietly force water back under your shingles and into your home, leading to damage you often won’t notice until it’s already expensive.

What Is Ice Damming?

Ice damming occurs when snow on your roof melts and refreezes near the eaves. Over time, this creates a barrier of ice that traps water behind it. That trapped water has nowhere to go… except back under your roofing materials.

What Causes Ice Damming?

Ice dams are usually a sign that your home is losing heat where it shouldn’t. Common causes include:

• Heat escaping into the attic, warming the roof surface

• Poor insulation or ventilation, allowing uneven roof temperatures

• Clogged soffits or insufficient roof vents

• Heavy snow buildup combined with fluctuating temperatures

Even well-built homes can experience ice damming during harsh winters.

Why Ice Damming Is a Big Deal

Ice dams don’t just affect the exterior of your home. The real damage happens behind the scenes:

• Interior water damage to ceilings and walls

• Mold and mildew growth from trapped moisture

• Ruined insulation, reducing your home’s energy efficiency

• Structural damage to roof decking and framing

• Costly repairs that insurance may not fully cover

By the time water stains appear indoors, the problem has usually been there for a while.

The Good News: Ice Damming Is Often Preventable

Most ice damming issues can be prevented, or minimized, when caught early. A few proactive steps can make a big difference:

• Keep attic insulation and ventilation up to standard

• Ensure soffits and vents are clear of snow and debris

• Safely remove excess snow from the roof after major storms

• Address heat loss issues before winter hits

• 
  

If you’re noticing recurring ice buildup, it’s worth having a professional assess your attic and roof ventilation.

Protect Your Home (and Your Peace of Mind)

Winter is hard enough on a home without hidden water damage adding to the mix. If you see ice dams forming, don’t ignore them, your roof is trying to tell you something.

A little attention now can prevent a major headache (and repair bill) later.
