Yes, a Roof Still Leaking After Repair Is Common in Winnipeg, Here's Why and What It Costs to Fix
If your roof is still leaking after a recent repair in Winnipeg, you're not alone, and the fix will typically cost between $250 and $1,200 depending on what was missed the first time. The most common reasons are simple: the original roofer patched the wrong spot, didn't address flashing or vent boots, or the freeze-thaw cycle opened a new gap within weeks. We fix these properly by finding the actual source of the water intrusion, not just the stain on your ceiling.

Why Your Roof Is Still Leaking After a Repair
Water is patient and sneaky. It travels along rafters, insulation, and sheathing before it ever drips onto your floor. A roof can be leaking in one spot while the water shows up three or four feet away. This is the number one reason repairs fail: the roofer sealed the visible part of the problem but missed the entry point entirely.
In Winnipeg, the freeze-thaw cycle makes this worse. We get more than 40 freeze-thaw events every year, and each one expands and contracts your roofing materials. Small gaps open up, ice dams form at the eaves, and flashing that was fine in September can be lifting by November. If your repair was done before a deep freeze, the next thaw can undo it.
Other common causes include:
- Flashing that was never replaced, step flashing around chimneys and walls is the most common leak point on Winnipeg roofs.
- Vent boots cracked by UV and cold, the rubber boots around plumbing vents dry out and split within five to seven years.
- Ice dams, if the repair didn't address attic heat loss and ventilation, the ice dam will return and push water back under the shingles.
- Hail damage that was missed, a previous inspection may have missed granule loss or bruising on asphalt shingles that doesn't show until the next heavy rain.
- The wrong material was used, exterior-grade caulking fails in our winters; proper roofing cement and compatible flashing are required.

Roof Still Leaking After Repair: Pricing in Winnipeg
The starting price for this service is $250 to $1,200, but the final cost varies a lot depending on job size, scope, and site conditions. We never quote a firm price over the phone without seeing your roof first.
Here's a rough breakdown of what drives the cost:
| Scope of Work | Typical Range |
|---|---|
| Flashing repair around a chimney or wall | $250–$700 |
| Vent boot replacement (one to three boots) | $250–$600 |
| Shingle replacement for a localized leak area | $200–$800 |
| Ice dam removal and de-icing | $200–$800 |
| Interior ceiling and drywall repair | $200–$800 |
| Full leak investigation with thermal imaging | $150–$300 |
| Complex leak tracing with multiple entry points | $400–$1,200 |
These ranges are starting points only. The final cost varies a lot depending on job size, scope, and site conditions. A two-storey home with a steep pitch will cost more than a bungalow. A leak that's been active for months may have damaged sheathing or insulation, which adds to the scope. We'll give you an exact number after we inspect.
Our Process: How We Fix a Roof That's Still Leaking
Step 1: Free Inspection and Leak Assessment
We come to your Winnipeg home, inspect the roof from the outside, and check the attic from the inside. We look for water trails, stained sheathing, rusted nails, and compromised flashing. If needed, we use thermal imaging to find moisture trapped inside the roof assembly.
Step 2: Honest Diagnosis
We tell you exactly what's leaking and why the previous repair failed. If a repair will solve the problem for the next 10 to 15 years, we'll recommend that. If the roof is at the end of its service life, say, an asphalt shingle roof past 20 years with widespread granule loss, we'll tell you honestly that a replacement is smarter money. No sales pressure, just the facts.
Step 3: Repair-First Quote
You get a written quote before we start. No surprises, no change orders unless you approve them. The person who quotes your roof is the person who repairs it. That's how we keep our pricing fair and our quality accountable.
Step 4: The Repair
We do the work properly the first time. That means pulling back shingles to inspect the decking, replacing damaged flashing rather than caulking over it, and using materials rated for Winnipeg winters. Most repairs take one day or less.
Step 5: Water Test and Follow-Up
We test the repair by running water over the repaired area where possible. We also check the interior for any remaining active leaks. If the leak was caused by ice dams, we'll recommend ventilation or insulation upgrades to prevent it from happening again next winter.
