If you’ve lived through a Central Ohio winter, you know the drill: temperatures swing from freezing to thaw and back again, sometimes within the same week. This freeze-thaw cycle creates perfect conditions for one of the most damaging winter roof problems—ice dams.
Those sparkling icicles hanging from your roofline might make for a charming winter scene, but they’re often the visible warning sign of a much bigger issue forming just out of sight.
What Is an Ice Dam?
An ice dam is a ridge of ice that forms along the edge of your roof, typically above the gutters. When heat escapes from your attic, it warms the roof surface and melts the snow sitting on top. That meltwater runs down toward the eaves—the coldest part of the roof—where it refreezes into a solid barrier of ice.
As more snow melts and flows down, it gets trapped behind this ice ridge. With nowhere to go, water pools on your roof and eventually finds its way under shingles, into your attic, and down through your ceilings and walls.
The result? Water stains, peeling paint, damaged insulation, mold growth, and in severe cases, structural damage that requires extensive repairs.
Why Central Ohio Homes Are Vulnerable
Our region’s winter weather patterns make ice dams especially common. Columbus and the surrounding areas experience frequent temperature fluctuations—a sunny 40-degree afternoon followed by a 15-degree night is nothing unusual in January or February.
Older homes in neighborhoods like Clintonville, German Village, and Worthington often have less attic insulation than modern building codes require. Historic charm sometimes comes with drafty attics that lose heat quickly, warming the roof from below and accelerating the melt-freeze cycle.
Even newer construction isn’t immune. Homes with complex roof designs, multiple dormers, or cathedral ceilings can develop ice dams if ventilation isn’t properly balanced.
Warning Signs to Watch For
Catching ice dams early can save you thousands in repairs. Here’s what to look for:
Icicles forming along the roof edge. A few small icicles aren’t cause for panic, but large icicles or a continuous “curtain” of ice along your gutters indicates significant melt-freeze activity.
Ice buildup in gutters. If your gutters are packed with ice or you notice ice extending up onto the roof surface above them, a dam is likely forming.
Water stains on ceilings or walls. Brown spots appearing on upper-floor ceilings during or after cold snaps often point to ice dam leaks.
Frost or moisture in the attic. If you can safely access your attic, look for frost on the underside of the roof sheathing or wet insulation—both signs that water is infiltrating.
Sagging or damaged gutters. Ice is heavy. Gutters pulling away from the fascia or showing signs of strain may be bearing the weight of ice dam buildup.
What NOT to Do
When homeowners spot an ice dam, the instinct is often to grab a ladder and start chipping away. This is dangerous for several reasons.
Climbing onto an icy roof—or even a ladder against an icy house—creates serious fall risks. Beyond personal safety, hacking at ice with a hammer or ice pick can crack shingles, puncture the roof membrane, or damage gutters beyond repair.
Salt and chemical deicers marketed for roofs can corrode metal flashing, kill landscaping below, and stain roofing materials. The short-term fix often creates long-term problems.
If you’re dealing with an active leak, the safest immediate step is to place buckets to catch water and call a professional who has the equipment and experience to address the situation safely.
Prevention Starts in the Attic
The most effective way to prevent ice dams is to keep your roof cold. That might sound counterintuitive, but a cold roof means snow stays frozen rather than melting, running down, and refreezing at the edge.
Proper attic insulation keeps warm air inside your living space instead of escaping through the ceiling. Adequate ventilation—typically a combination of soffit vents and ridge vents—allows cold outside air to circulate under the roof deck, maintaining a consistent temperature.
Sealing air leaks around light fixtures, attic hatches, plumbing stacks, and ductwork prevents warm air from sneaking into the attic. These small gaps add up quickly and contribute to uneven roof temperatures.
A professional roof inspection can identify ventilation deficiencies, insulation gaps, and other vulnerabilities before winter weather puts them to the test.
When to Call a Professional
If you notice water coming into your home during winter, don’t wait to see if it gets worse—it usually does. Prompt action can prevent a manageable repair from becoming a major restoration project.
A roofing professional can safely remove ice dams using steam equipment that melts ice without damaging your roof. They can also identify the entry points where water is penetrating and recommend repairs once conditions allow.
More importantly, a thorough inspection after winter helps you understand why the ice dam formed in the first place, so you can address the root cause before next season.

Frequently Asked Questions
What causes ice dams on roofs?
Ice dams form when heat escaping from your attic melts snow on the roof. The meltwater runs down to the colder roof edge where it refreezes, creating a barrier that traps additional water and forces it under your shingles."
Are ice dams covered by homeowners insurance?
Most homeowners insurance policies cover water damage caused by ice dams, though coverage varies. The damage itself is typically covered, but repairs to prevent future ice dams may not be. Check with your insurance provider for specifics."
Can I remove an ice dam myself?
We don't recommend it. Climbing on icy roofs is extremely dangerous, and chipping at ice can damage shingles and gutters. If you have an active leak, place buckets to catch water and call a professional with proper equipment."
How do I prevent ice dams from forming?
Prevention focuses on keeping your roof consistently cold. This means ensuring adequate attic insulation, proper roof ventilation, and sealing air leaks that allow warm air to escape into the attic space."
When should I get my roof inspected for ice dam damage?
If you've experienced ice dams or interior water damage this winter, schedule an inspection as soon as weather permits. A professional can identify damage and recommend repairs before small issues become major problems."
"During a rainy downpour, I noticed a leak inside my house. More rain was predicted. My insurance company recommended Chris. Communication and followup is important to me. I called, left a message and Chris quickly returned my call. Chris came over to inspect the roof and put up a tarp not knowing if we would do further business. Chris was constantly in communication and answered all my questions. The quote was fair and accurate, no unexpected charges. Chris and the team were on time, professional and did a great job! I highly recommend Chris and KFX roofing and have already referred them."
