Ice Dam Removal

Ice dams form when heat escaping from your attic melts snow on the upper roof. The meltwater runs down to the cold eave, where it refreezes into a ridge of ice. That ridge traps water behind it, forcing it up under the shingles and through the roof deck. The result is water in your ceilings, walls, and insulation — often far from the actual dam. Our ice dam removal service uses professional steam equipment to remove the dam safely, then repairs the interior water damage it caused.

Signs of Ice Dam Damage

Ice dam water damage is not always obvious at first. Water travels along framing before it becomes visible. Look for these signs during and after a winter storm:

• Water stains on ceilings — yellow or brown patches that grow over time, often near exterior walls or the eaves. The stain may appear several feet from the dam itself.
• Sagging or bubbling drywall — water pooling above the ceiling drywall causes it to sag at the seams or bubble at the paint layer. This means the drywall is saturated and must be replaced.
• Water dripping from light fixtures — water travels along ceiling joists and drips through the nearest opening. A dripping light fixture is a sign of active water intrusion above.
• Wet insulation in the attic — insulation at the eaves that is damp or matted down has lost its R-value. Wet insulation must be removed and replaced.
• Ice buildup on the roof edge — visible ice ridges along the eaves, often with icicles hanging from the gutter. The thicker the ice ridge, the more water is trapped behind it.
• Peeling paint or wallpaper near windows — water running down inside wall cavities emerges at the weakest point, often around window and door frames on exterior walls.

How Ice Dams Form

Three conditions are needed to create an ice dam. First, snow accumulates on the roof. Second, heat from the attic warms the upper roof surface and melts the snow from below. Third, the eaves stay cold enough to refreeze the meltwater. This temperature difference between the warm upper roof and the cold eave is what drives the cycle.

The main cause of attic heat loss is poor air sealing and insufficient insulation. Warm air leaks through gaps around plumbing vents, electrical wiring, recessed lights, and attic hatches. That warm air heats the underside of the roof deck, melting the snow above it. The meltwater flows down to the eave, hits the cold surface, and refreezes. Over hours and days, the ice ridge builds up and water backs up behind it.

The weight of an ice dam can also damage gutters, pulling them away from the fascia board. Ice dams that form in valleys or at dormer intersections place additional stress on the roof structure.

Our Ice Dam Removal Process

1. Inspect the roof and interior — We assess the ice dam size, thickness, and location. We also check the interior for active water intrusion — wet ceilings, dripping water, and saturated insulation. This tells us the full scope of the problem.

2. Set up the steam equipment — We use propane-powered steamers that produce low-pressure, high-temperature steam. The equipment is set up on the ground or on the roof depending on the building height and roof pitch. All work is done with fall protection and safety lines.

3. Steam the ice dam — The steam melts channels through the ice dam, allowing trapped water to drain off the roof. We work from the top of the dam downward, melting the ice in sections. The steam is hot enough to melt ice but does not damage shingles, underlayment, or flashing.

4. Manage runoff — As the ice melts, we direct the water away from the building and away from areas where it could refreeze. We clear gutters and downspouts so melted water flows freely.

5. Inspect for interior damage — Once the dam is removed and the roof is clear, we inspect the interior again. We document any water damage to ceilings, walls, insulation, and framing for your insurance claim.

6. Dry and repair — Wet insulation is removed and replaced. Water-damaged drywall is cut out and replaced. Ceilings are primed with stain-blocking primer and repainted. We also address any roof damage caused by the ice dam or the trapped water.

Ice Dam Removal Costs

Service	Typical Cost Range	What Is Included
Steam removal (small dam)	$400 - $800	One to two hours of steaming, runoff management, roof inspection
Steam removal (large dam)	$800 - $1,500	Two to four hours of steaming, multiple access points, full roof inspection
Interior ceiling repair	$300 - $1,200	Cutting out wet drywall, staining blocking primer, repainting, texture matching
Attic insulation replacement	$500 - $2,000	Removing wet insulation, air sealing gaps, installing new fiberglass or blown-in insulation
Full ice dam + interior repair	$1,200 - $4,000	Steam removal, interior drywall repair, insulation replacement, paint

Costs vary by roof height, pitch, ice dam size, and the extent of interior damage. The free inspection provides an exact quote.

DIY vs Professional Ice Dam Removal

Many homeowners try to remove ice dams themselves. The methods are dangerous and often cause more damage than the ice dam itself.

DIY methods to avoid:

• Ice chippers and roof rakes — These tools chip away at the ice but also crack and lift shingles. A cracked shingle leaks water long after the ice dam is gone. Roof rakes used from the ground can pull off snow but also damage shingles if the blade catches an edge.
• Axes, hammers, and picks — Impact tools puncture shingles, damage underlayment, and create new leaks. The roof deck may also be damaged, requiring replacement of multiple sheets of plywood.
• Rock salt or calcium chloride — Salt corrodes gutters, damages shingles, and kills plants below the roofline. It also takes days to work and is only effective on thin ice. The runoff contains chemicals that harm landscaping.
• Hot water — Pouring hot water on an ice dam melts the surface ice, but the water refreezes quickly on the cold roof. It can also damage shingles if the water is too hot.

Professional steam removal is the only safe method. Steam penetrates the ice without impact. It does not damage shingles, underlayment, flashing, or gutters. The equipment is purpose-built for this task, and our crews are trained in roof safety and ice dam removal techniques.

Preventing Ice Dams

The most effective ice dam prevention addresses the root cause — heat loss through the attic. If the roof deck stays cold, snow does not melt unevenly, and ice dams do not form.

• Attic air sealing — Seal every gap between the living space and the attic. This includes plumbing vents, electrical boxes, recessed light fixtures, attic hatches, and the tops of interior walls. Canned spray foam and caulk work for small gaps. Larger gaps need rigid foam board or sheet metal.
• Attic insulation — Increase attic insulation to R-38 or higher depending on your climate zone. Blown-in cellulose or fiberglass works well. The insulation must be evenly distributed with no thin spots. Insulation baffles keep soffit vents clear.
• Soffit and ridge vents — Proper attic ventilation keeps the roof deck cold. Soffit vents draw cold air in at the eaves. Ridge vents exhaust warm air at the peak. Both must be clear of insulation, debris, and rodent nests.
• Ice and water shield — During roof replacement, install a self-adhering ice and water shield membrane at the eaves. This membrane seals around nail penetrations and prevents water from backing up under shingles behind an ice dam. It is the last line of defense.
• Gutter maintenance — Clean gutters in the fall to prevent ice buildup. Ice dams form more easily in gutters full of leaves and debris. Install gutter guards to reduce debris accumulation.

Expert tip: Steam removal is the only ice dam removal method that does not damage your roof. Ice chippers, axes, and salt all cause damage that leads to new leaks. If a contractor shows up with an axe, send them away.

Ice Dam Removal by State

Ice dam removal demand tracks the northern snow belt and mountain climates. In New England and the upper Midwest, long, snowy winters make ice dams a recurring seasonal problem, and crews stay busy from December through March. In the Mountain West, high snowfall at elevation and freeze-thaw cycles create ice dams even in relatively mild winters. Mid-Atlantic states see ice dams during occasional heavy snow events. Even parts of the Pacific Northwest, where snowfall is intermittent, experience ice dams when snow on the roof melts over a warm attic and refreezes at the eave. Our local crews are experienced with the winter conditions of their region and respond quickly when an active ice dam is causing interior leaks.
