Ice Dams
How They Form, the Damage They Cause, and How to Prevent Them


Winter weather in Massillon, Canton, Akron, and Medina can be brutal on your home — especially your roof. One of the most common cold-weather roofing problems homeowners face is ice dams. If left unchecked, ice dams can lead to serious water damage, costly repairs, and interior leaks.
As a trusted roofing contractor, Alpha Kings Construction wants homeowners to understand how ice dams form and what you can do to prevent them.
What Is an Ice Dam?
An ice dam forms when snow on your roof melts and refreezes at the roof’s edge. This creates a ridge of ice that blocks proper drainage. As melting snow backs up behind the ice dam, water can seep under shingles and into your home — even on newer roofs.
Ice dams are extremely common in Northeast Ohio due to fluctuating winter temperatures.
How Ice Dams Form
Ice dams typically form due to uneven roof temperatures. Here’s how it happens:
- Heat escapes from your attic, warming the roof surface
- Snow melts on the upper sections of the roof
- Melted snow runs down to the colder eaves
- Water refreezes, creating a dam of ice
- Additional melting water backs up behind the dam
- Water finds its way under shingles and into walls or ceilings
This process can happen repeatedly throughout winter, increasing the risk of roof leaks and water damage.
Signs You May Have an Ice Dam
- Large icicles hanging from gutters
- Water stains on ceilings or walls
- Peeling paint near exterior walls
- Dripping water during freezing temperatures
- Ice buildup along roof edges
If you notice any of these signs, it’s time to call a roofer near you before the damage worsens.
Damage Caused by Ice Dams
Ice dams can lead to serious issues, including:
- Roof leaks
- Damaged shingles and underlayment
- Wet insulation
- Mold growth
- Drywall and ceiling damage
- Rotting wood framing
Many homeowners don’t realize the damage until spring — when repairs are often more expensive.
How to Prevent Ice Dams from Forming
1. Improve Attic Insulation
Proper insulation keeps heat inside your home and prevents snow from melting unevenly on your roof.
2. Seal Air Leaks
Gaps around attic hatches, light fixtures, and bathroom fans allow warm air to escape and heat the roof.
3. Ensure Proper Roof Ventilation
Balanced ventilation helps maintain consistent roof temperatures and reduces ice dam formation.
4. Clear Snow Safely
Using a roof rake after heavy snowfall can help reduce buildup — never climb on an icy roof.
5. Install Ice & Water Shield
As a professional roofing contractor, Alpha Kings Construction installs ice and water shield along roof edges for added protection against water intrusion.
6. Keep Gutters Clean
Clogged gutters trap water, increasing the chance of freezing and ice buildup.
What to Do If Ice Dams Cause Water Damage
If you suspect ice dam damage:
- Contain interior leaks immediately
- Document damage for insurance
- Avoid chipping ice off the roof
- Call a professional roofer
Quick action can prevent further water damage and costly structural repairs.
