Steam removal for ice dams in Winnipeg typically runs $300–$800 for a standard two-storey home with 20–40 linear feet of dam, while shoveling runs $200–$500, and the roof repair that becomes necessary after a dam has pushed water under shingles runs $200–$1,200, but every one of those numbers moves dramatically based on roof pitch, ice thickness, how many spots are leaking, and what the freeze-thaw cycle has already done to your asphalt shingles. The honest answer is that most Winnipeg homeowners end up paying for two of the three, because shoveling too late or steaming too early leaves damage that a repair crew finds in spring.
Why Ice Dams Are A Winnipeg Problem, Not Just A Cold-Weather Problem
Winnipeg sits in a freeze-thaw zone that few Canadian cities match. We get stretches of -30°C, then a chinook-style warm spell that pushes rooftop temperatures above freezing while the ground stays frozen solid. That pattern is exactly what builds ice dams. Snow melts off the warm upper roof, runs down to the cold eaves, and refreezes into a ridge of ice. Every subsequent melt adds to it.
The dam itself isn't the real problem. The problem is the water ponding behind it. That water backs up under asphalt shingles, works its way around flashing, and runs down into the wall cavity or ceiling below. By the time you see a stain on your ceiling, the water has already found a path through the roof deck, the insulation, and the drywall. That's why ice dam removal in Winnipeg is as much about speed as it is about technique.
The cost of removing the ice is almost always lower than the cost of repairing what the ice lets in. A $400 steaming job beats a $900 interior ceiling repair plus a $600 flashing repair every single time.
What Steam Removal, Shoveling, And Repair Actually Cost In Winnipeg
Let's break the real numbers down by approach. These are typical Winnipeg ranges from our own work and from what we see on insurance claims across the city.
Steam Removal, $300–$800
Steam removal is the gold standard. A crew brings a commercial steam unit, melts channels through the dam so water can drain off the roof, and clears the eaves without damaging shingles. It's fast, it's clean, and it's the only method that removes the ice without prying, chopping, or scraping at your roof surface.
For a typical Winnipeg two-storey home with 30 linear feet of dammed eave, expect $300–$600. A larger home, a steep-pitch roof, or a dam that's built up over multiple freeze-thaw cycles pushes that toward $700–$800. The final cost varies a lot depending on job size, scope, and site conditions, a bungalow with a shallow-pitch roof and 15 feet of dam is a completely different job than a two-storey with 50 feet of ice and three layers of buildup.
Shoveling And Manual Removal, $200–$500
Shoveling the snow off the roof before it melts is the cheapest option, and it's the one we recommend you do preventively. A crew clears the snow from the lower 6–8 feet of the roof, which removes the fuel for the dam. That runs $200–$400 for most Winnipeg homes.
Chopping the ice itself with an axe, a pry bar, or a hammer is cheaper in the moment, often $150–$300, but it's the most dangerous option for your roof. Every strike risks cutting into asphalt shingles, cracking flashing, or denting the metal valley. We've seen more spring leaks caused by aggressive ice chopping than by the dams themselves. If you're going to clear ice manually, the cost of the repair you might cause needs to be part of the math. The final cost varies a lot depending on job size, scope, and site conditions.
Roof Repair After Ice Damage, $200–$1,200
This is the number that catches people off guard. After the dam melts, the damage is already done in many cases. Water that backed up under the shingles has soaked the underlayment, rotted the roof deck, or corroded the flashing. The repair cost depends entirely on what the water touched.
- Flashing repair around a chimney, vent, or valley: $150–$800
- Shingle replacement on a section where the granules are gone and the mat is exposed: $200–$1,500
- Roof deck replacement where the plywood has delaminated or rotted: $400–$1,200 for a small section
- Interior ceiling repair where the water broke through drywall: $200–$800
The final cost varies a lot depending on job size, scope, and site conditions. A small flashing fix on a single-storey addition is a different job than a deck repair on a steep two-storey roof with a 50-foot reach.
What's Included In A Professional Ice Dam Removal Visit
if you hire Roof Repair Winnipeg for ice dam removal, what the visit actually includes:
Inspection first. We get on the roof (or use a ladder and a careful walk if conditions allow) and assess the dam's thickness, the extent of the ice, and the condition of the shingles and flashing underneath. We also check the attic side, ventilation, insulation levels, and any signs that moisture has already entered.
Steam channels. We melt vertical channels through the dam at regular intervals so trapped water can drain off the roof. This relieves the hydrostatic pressure behind the dam, which is what stops the water from pushing under shingles.
Eave clearing. We clear the ice from the eave edge so the roof can shed water normally again.
Debris removal. Snow and ice that we remove goes off the roof and away from your foundation. We don't leave piles that refreeze against your siding or your basement walls.
A written assessment. You get a summary of what we found, what we did, and whether there's any damage that needs a follow-up repair. If there is, you get a straight answer on whether it's a repair or a replacement, and the price for both.
When Ice Dam Removal Turns Into A Roof Repair
Here's the scenario we see every winter in Winnipeg. A homeowner notices a ceiling stain in late January. They call a crew to steam the dam. The dam comes off, the leak stops, and everyone assumes the problem is solved. Then in April, the shingles at the eave start lifting, or the flashing around the chimney is visibly corroded, or the plywood deck feels spongy underfoot.
That's the second bill. And it's always higher than the first.
The repair-first approach matters here. A lot of Winnipeg roofers will look at a roof with ice damage and quote a full replacement, $8,000–$15,000, because it's an easier sell than tracing the water path and fixing the specific failure points. But most ice damage is localized. The eave section where the dam formed is the damaged area. The rest of the roof is fine. Replacing 20 square feet of shingles and re-flashing one chimney is a $400–$1,200 job, not a $12,000 one.
The honest math is this: if your roof is under 15 years old and the damage is confined to the eave line, a repair is almost always the right call. If your roof is 20+ years old, has multiple layers of shingles, and the ice damage is widespread, replacement might be cheaper than chasing leaks for the next three winters. We'll tell you which one you're looking at.
The Insurance Question, What's Covered And What Isn't
Winnipeg homeowners ask about insurance for ice dam damage more than any other winter roofing question. The short answer: it depends on whether the dam caused damage or the dam was the damage.
If water from an ice dam soaked your ceiling, damaged your drywall, or rotted your roof deck, that's typically a covered water damage claim. Your policy's water damage coverage usually applies, minus your deductible (typically $1,000–$2,500 in Manitoba).
If you're calling to have the ice dam removed before it causes damage, that's preventive maintenance. Most policies don't cover preventive removal. The $300–$800 steam removal bill is on you.
There's a grey zone, and it's worth knowing about. If the ice dam has already pushed water into the home, visible staining, dripping, or saturated insulation, the removal of the dam is often bundled into the water damage claim as part of mitigating further loss. That's the argument your adjuster will hear from us, and we write our inspection reports with that language in mind. We're not insurance adjusters, and we don't guarantee claims, but we document what we see and we make the cause-and-effect clear.
One thing we tell every Winnipeg homeowner: don't wait for the leak to start before calling. If you see a dam forming and the forecast calls for another freeze-thaw cycle, the $400 you spend on steam removal now is the $2,000 you save on a claim deductible plus the repair you'd need anyway.
How To Prevent The Next Ice Dam
Ice dam prevention in Winnipeg is about the roof assembly, not just the roof surface. what actually works:
Ventilation. A cold roof is a dry roof. If your attic doesn't have enough intake at the soffits and exhaust at the ridge, heat from the living space warms the underside of the roof deck, melts the snow, and feeds the dam. Adding ridge vent and improving soffit flow runs $300–$1,500 depending on the size of your roof and how much needs to be opened up.
Insulation. The second half of the cold-roof equation. If your attic insulation is below R-40, you're losing heat through the ceiling. Topping up insulation is one of the cheapest things you can do for ice dam prevention, and it pays for itself in heating bills within a couple of winters.
Flashing and shingle condition. Dams form where the roof surface is uneven or where flashing has lifted. A granule-worn asphalt shingle absorbs more heat and melts snow faster than a healthy one. Flashing that's pulled away from a chimney or vent lets meltwater run behind it and freeze. Keeping these in good shape is a $200–$800 annual maintenance cost, not a capital expense.
Early snow removal. The cheapest preventive measure is also the simplest. If you clear the lower 6 feet of snow off your roof after every significant snowfall, you never give the dam a chance to build. At $200–$400 per visit, even five visits a winter is cheaper than one repair.
Why Roof Repair Winnipeg For Ice Dam Work
We're a small crew, and that's the point. We don't have a sales team. The person who answers your call is the person who shows up, gets on your roof, and does the work. That keeps our overhead low and our prices fair, and it means the advice you get is from someone who has actually fixed roofs in Winnipeg through every freeze-thaw cycle this city throws at us.
We quote the repair, not the replacement. When we do an ice dam removal and find damage, we tell you honestly what needs fixing, what can wait, and what's not worth fixing. If a repair is smarter than a new roof, we say so. If a new roof is the better long-term move, we'll show you the math.
We handle the whole scope of ice dam and winter leak work across Winnipeg and surrounding communities, from St. Vital to Charleswood, from Transcona to East St. Paul. That includes steam removal, shingle and flashing repair, roof deck replacement where water has done its worst, and the interior ceiling work that follows a leak.
And when the dam is part of a bigger storm damage picture, Winnipeg's May-to-September hail season means a lot of roofs are already compromised when winter hits, we respond within 24–48 hours and write an adjuster-ready damage report with every inspection.
