Safe steam removal. Leak repair. Permanent prevention. We stop ice dams from destroying your roof and causing thousands in interior water damage.
How Ice Dams Form and Damage Your Roof
Ice dams are a uniquely cold-climate roofing problem, and New Jersey's freeze-thaw winter cycles create ideal conditions for their formation. An ice dam develops when heat escaping from your home's interior warms the roof deck above 32°F, melting snow on the upper roof. This meltwater flows downhill until it reaches the cold eaves overhang — where no interior heat reaches — and refreezes into a thickening ridge of ice.
As the dam grows, subsequent meltwater backs up behind it and is forced under shingles, bypassing all normal waterproofing and leaking into your home. The damage is often severe because water intrusion occurs at the eaves, where it can damage ceiling drywall, wall framing, insulation, and exterior soffits simultaneously.
Prolonged exposure during multi-day freeze cycles allows water to penetrate deeply into building materials, creating conditions for mold growth and structural deterioration that may not become apparent until spring. This is why prompt professional intervention is critical.
The Ice Dam Formation Cycle
Heat escapes through inadequate attic insulation, warming the roof deck
Warm deck melts snow on the upper roof, creating meltwater that flows downhill
Water reaches the cold eaves and refreezes, building an ice ridge that traps water
Trapped water backs up under shingles and leaks into your home's interior
Warning Signs of Ice Dam Damage
Exterior Signs
- ✓Large icicles hanging from eaves or gutters
- ✓Thick ice buildup along the roof edge
- ✓Gutters sagging, pulling away, or filled with ice
- ✓Ice forming on exterior walls below the eaves
- ✓Uneven snow melt pattern (bare patches on upper roof, snow at eaves)
Interior Signs
- ✓Water stains on ceilings near exterior walls
- ✓Peeling or bubbling paint on walls or ceilings
- ✓Damp or musty smell in upstairs rooms
- ✓Wet spots in attic insulation
- ✓Active dripping from ceiling during freeze-thaw days
How to Handle Ice Dam Damage on Your Roof
Call for professional ice dam removal
If you notice icicles forming at your eaves, water stains on interior ceilings or walls, or ice buildup in gutters, call R&E Roofing at (667) 204-1609. Do not attempt to chip or hammer ice -- this damages your roof and is extremely dangerous.
Professional steam removal
Our crews use commercial steam equipment to safely melt ice dams and create drainage channels for trapped water. Steam is the only method that removes ice without damaging shingles, gutters, or flashing beneath the ice.
Inspect for water intrusion damage
Once ice dams are removed, we inspect the roof for water damage to shingles, underlayment, and decking. We also check interior areas for water stains, wet insulation, and early signs of mold in the attic space.
Repair any roof damage
We repair or replace any damaged roofing materials, reseal compromised areas, and restore your roof's waterproof integrity. All repairs use materials rated for freeze-thaw cycling common in NJ winters.
Implement permanent prevention
Based on our attic inspection, we recommend and install prevention measures: improved ventilation (soffit and ridge vents), ice and water shield membrane at eaves, and coordination with insulation contractors for attic improvements.
Permanent Ice Dam Prevention for NJ Homes
The root cause of ice dams is almost always inadequate attic insulation, poor ventilation, or both. When warm air escapes into the attic space, it heats the roof deck unevenly, creating the temperature differential that drives ice dam formation. Fixing this at the source eliminates ice dams permanently.
Attic Insulation Upgrade (R-49+)
Adding insulation to R-49 or higher stops heat from reaching the roof deck. This is the single most effective ice dam prevention measure. We assess your current insulation levels and recommend targeted improvements. Typical cost: $1,500-$3,000.
Soffit-to-Ridge Ventilation
Continuous ventilation keeps the underside of the roof deck cold by flushing warm attic air out through ridge vents while drawing cold outside air in through soffit vents. We install and repair ventilation systems to create proper balanced airflow. Typical cost: $500-$2,000.
Ice and Water Shield Membrane
A self-sealing waterproof membrane installed under shingles at the eaves (minimum 3 feet past the exterior wall). Even if an ice dam forms, the membrane prevents water intrusion. We install this during roof replacements and can retrofit it in some cases. Included with roof replacement; standalone installation: $800-$2,000.
Heat Cable Systems
Electric heat cables installed along eaves and in gutters prevent ice from forming in problem areas. While not a substitute for proper insulation and ventilation, heat cables are effective as a supplemental measure for persistent problem areas. Typical cost: $500-$1,500.
Ice Dam Service Costs
| Service | Typical Cost |
|---|---|
| Emergency ice dam removal (steam) | $500 - $1,500 |
| Roof leak repair from ice dam damage | $500 - $2,500 |
| Attic insulation upgrade (to R-49+) | $1,500 - $3,000 |
| Ventilation improvement | $500 - $2,000 |
| Ice and water shield installation | $800 - $2,000 |
| Heat cable system | $500 - $1,500 |
Costs vary based on roof size, accessibility, and specific conditions. All pricing includes materials and labor. Free estimates provided.

Ice Dam Roof Damage FAQ
What causes ice dams on my roof?
Ice dams form when heat escaping from your home's interior warms the upper roof deck above 32°F, melting snow on the roof. The meltwater flows downhill until it reaches the cold eaves overhang (where no interior heat reaches) and refreezes into a growing ridge of ice. As the dam thickens, subsequent meltwater backs up behind it and is forced under shingles, bypassing all waterproofing. The root cause is almost always inadequate attic insulation, poor ventilation, or both.
Can I remove an ice dam myself?
We strongly advise against DIY ice dam removal. Hammering, chipping, or using rock salt damages shingles, gutters, and flashing -- often causing more harm than the ice dam itself. Climbing on an icy roof is extremely dangerous. Professional steam removal is the only safe, effective method that eliminates the dam without causing additional damage to your roof.
How do I prevent ice dams permanently?
The most effective permanent prevention combines three approaches: adding attic insulation to R-49 or higher to stop heat from reaching the roof deck, ensuring proper soffit-to-ridge ventilation for continuous cold airflow under the roof deck, and installing ice and water shield membrane along eaves during your next roof replacement. Addressing all three eliminates the temperature differential that causes ice dams.
Will ice and water shield prevent ice dam leaks?
Ice and water shield installed along eaves (minimum 3 feet past the interior wall line) provides a waterproof self-sealing membrane that prevents leaks even when water backs up behind an ice dam. It does not prevent ice dam formation, but it stops the resulting water damage. We install this on all new roofs and replacements in Essex County.
Do ice dams damage gutters?
Yes, ice dams can severely damage gutters. The weight of ice buildup (which can exceed hundreds of pounds) can pull gutters away from the fascia, bend or crush gutter troughs, crack gutter seams, and damage downspout connections. We inspect and repair all gutter damage as part of our ice dam service.
When is ice dam season in New Jersey?
Ice dams typically form during December through February when snowfall combines with freeze-thaw cycles. January is historically the peak month in Essex County, NJ. Nor'easters that bring heavy snow followed by sunny days create the worst ice dam conditions. Even modest snowfall can cause ice dams if your attic insulation is inadequate.
How much does ice dam removal and repair cost?
Emergency ice dam removal by steam typically costs $500-$1,500 depending on the extent of ice buildup and roof accessibility. Leak repairs resulting from ice dam damage range from $500-$2,500. Permanent prevention improvements (insulation, ventilation, ice and water shield) range from $1,000-$4,000 depending on scope. These investments prevent thousands in recurring damage.
