If water is dripping from a ceiling or running down a wall in the middle of winter and there's no rain, there's a decent chance you have an ice dam. Ice dams are one of the most common winter roof problems we see in Northeast Ohio. They are also misunderstood. The ice is a symptom, and the cause is usually heat escaping from inside your house.
What Is an Ice Dam?
An ice dam is a ridge of ice that forms along the lowest edge of your roof, at the eaves. Snow sits on the roof, some of it melts, and the meltwater is supposed to run down and off into the gutters. When a ridge of ice sits at the edge, that water has nowhere to go. It pools behind the dam, Shingles are built to shed water that runs downhill, not to hold standing water. The pooled water can work its way up under them and through the roof deck.
Why Do Ice Dams Form?
In most cases, heat from your house melts the snow on the roof, not the roof itself.
- Warm air from the living space leaks into the attic through gaps around light fixtures, attic hatches, chimneys, and plumbing, or through thin insulation.
- That heat warms the underside of the roof deck, and the snow on the warm part of the roof melts.
- The meltwater runs down to the eave, which sits over the cold overhang rather than the heated house. It refreezes there.
- Day after day, the frozen edge grows, and the next round of meltwater backs up behind it.
Northeast Ohio has both conditions that feed ice dams: lake-effect snow loads, and freeze-thaw swings that keep the cycle going. (We cover that in more detail in our guide to ice dam prevention in Northeast Ohio and on how freeze-thaw cycles damage roofs.)
What Should I Do Right Now If Water Is Coming In?
- Protect the inside first. Move furniture and belongings away from the leak, put a bucket under the drip, and lay down towels or plastic.
- Stay off the roof. A roof with ice and snow on it is dangerous to walk on, so do not climb up yourself.
- Don't hack at the ice. Chipping at ice with a hammer, shovel, or axe is how shingles get gouged and people get hurt.
- Take photos. Photograph the ceiling, the walls, the exterior ice, and the icicles. If you file an insurance claim, these photos are your record of the damage.
- Call a roofer. For an active leak, read our emergency roof repair guidance.
Does Removing the Ice Dam Fix the Leak?
Some contractors oversell this part. Clearing a dam, or steaming it off, deals with tonight's leak. It does not stop the next one. If the attic keeps leaking heat, the dam grows back the next time it snows and thaws.
The lasting fix is mostly not about shingles:
- Air sealing the gaps where heated air gets into the attic.
- Ventilation so the attic and roof deck stay cold. (See why roof ventilation matters in Ohio.)
- Ice-and-water shield along the eaves as the roof's last line of defense if a dam forms anyway.
Ventilation and ice-and-water shield are roofing work. Air sealing is not. Rockstar Roofing LLC, based in Ashtabula, Ohio, does not do air sealing, and it does not remove snow or ice. We repair the leaks that ice dams cause, and air sealing goes to an insulation contractor. If the real fix is outside our scope, I'll tell you that rather than sell you a roof you don't need.
Does an Ice Dam Mean I Need a New Roof?
An ice dam does not automatically mean replacement. If water has been getting under the shingles, the deck or insulation can be wet. A roof that has gone through repeated dam cycles may also have damaged shingles at the eaves. An inspection of the eaves, underlayment, and decking shows whether you need a repair or something bigger. Our repair vs. replacement guide walks through how to tell.

Frequently Asked Questions
What is an ice dam?
An ice dam is a ridge of ice that builds up along the lower edge of a roof, at the eaves. It blocks melting snow from draining, so the water pools behind it. That water can back up under the shingles and leak into the attic, ceilings, and walls.
Why do ice dams form?
Heat escaping from the living space warms the roof deck and melts the snow above it. The meltwater runs down to the colder eave, where it refreezes. Over days, that refrozen edge grows into a dam, and Northeast Ohio's lake-effect snow and freeze-thaw swings keep the cycle going.
Can an ice dam leak even if my roof is new?
Yes. Ice dams are mostly a heat-loss problem, so a new roof over an attic that leaks heat can still dam up. Ice-and-water shield at the eaves gives you a better defense, but it does not replace fixing the heat loss.
Should I chip the ice off my roof myself?
No. Chipping at ice with a hammer, shovel, or axe can gouge shingles, and a roof with ice and snow on it is a fall risk. Move belongings away from the leak, contain the water, take photos, and call a roofer.
How do I prevent ice dams?
Fix the cause: stop warm air from the house leaking into the attic, and ventilate the attic so the roof deck stays cold. Ice-and-water shield at the eaves adds protection if a dam forms anyway. Air sealing is work for an insulation contractor. Rockstar Roofing handles the ventilation and the eaves.
Does Rockstar Roofing remove ice dams?
No. Rockstar Roofing does not remove snow or ice. It repairs the leaks that ice dams cause, and it handles the roofing side of prevention: attic ventilation and ice-and-water shield at the eaves.
