Handling Winter Roof Leaks in Ottawa: A Homeowner’s Guide. There are few things more stressful for an Ottawa homeowner than hearing the steady drip-drip-drip of water coming from the ceiling in the middle of January. Winter in the National Capital Region is beautiful, but it is also relentless.
Between the freeze-thaw cycles, heavy snow loads, and biting winds, your roof endures a massive amount of stress. While we often think of roofing as a summer project, the reality is that roof leak repair is frequently required during the coldest months of the year.
If you suspect a roof leak or notice water stains on your ceiling this winter, do not panic, but do not wait. Water intrusion during winter can quickly escalate from a minor nuisance to significant structural damage.
At Godfrey Roofing, we have been protecting Ottawa homes since 1984. We know exactly how our local climate impacts roofing systems. In this guide, we will walk you through identifying winter roof leaks, the immediate steps you should take to minimize damage, and how professional roof repair in Ottawa can restore your peace of mind.
How to Spot a Winter Roof Leak
Winter roof leaks are often deceptive. Unlike a summer rainstorm, where water might drip directly below a hole, winter leaks frequently travel. Water from melting snow or ice dams can seep under shingles, travel along rafters, and drip onto your insulation or ceiling dozens of feet away from the actual breach.
Common Signs of winter roof leak Trouble:
- Water Stains: Yellow or brown rings on your ceiling or walls are the most obvious sign.
- Blistering Paint: If paint near your interior walls or ceiling starts to bubble, water is likely trapped behind it.
- Icicles on Siding: While icicles on gutters are common, icicles forming behind your eavestrough or running down your vinyl or brick siding often indicate water is bypassing your roof’s edge protection.
- Musty Odours: A persistent damp smell in your upper floors could indicate wet insulation in the attic.
The “Phantom” Leak: Sometimes, what looks like a roof leak is actually condensation. In Ottawa winters, warm, moist air from your home rises into the cold attic. If ventilation is blocked or insulation is insufficient, this air condenses on the cold roof deck, freezes, and then melts on a sunny day. This “attic rain” mimics a roof leak but requires a different solution, typically improved ventilation and insulation rather than a patch on the roof itself.
Immediate Steps: What to Do When You Find a Leak
If you discover active water intrusion, your priority is to minimize interior damage until a professional crew can arrive.
- Contain the Water: Clear the area under the drip. Move furniture, rugs, and electronics. Place a bucket under the leak. If the water is splashing, pin a string to the ceiling where the drip is originating and let the end hang in the bucket; water will travel down the string silently and without splashing.
- Relieve Ceiling Pressure: If you see a bulge in your drywall ceiling, it is holding a pool of water. This weight can cause the entire section of drywall to collapse. Using a screwdriver or a small nail, carefully poke a hole in the centre of the bulge to drain the water into your bucket. It sounds counterintuitive to make a hole, but a controlled drain is far better than a ceiling collapse.
- Do Not Climb on the Roof: We cannot stress this enough: safety is paramount. Climbing a snow-covered, icy, or wet roof in winter is incredibly dangerous for untrained individuals. Slippery shingles and hidden soft spots make DIY assessments risky. Leave the exterior inspection to professionals with the proper fall-arrest equipment.
- Call for Professional Help: Winter repairs require specialized techniques. Sealants that work in July often fail in January due to the cold. You need a team that uses winter-grade materials and safe ice-removal methods.

Why Do Roofs Leak in Winter?
Understanding the cause of your roof leak helps in choosing the right roof repair solution. In Ottawa, we see three primary culprits during the winter months.
Ice Dams
This is the most common cause of winter roof leaks in our region. An ice dam forms when heat escapes from your home and warms the roof deck, melting the snow. This meltwater runs down to the eaves (which are colder because they overhang the house) and refreezes.
Over time, this ridge of ice grows, blocking subsequent meltwater from draining. That water backs up, pools, and is forced under your shingles. Since shingles are designed to shed water downward, not withstand standing water, the water eventually finds a nail hole or gap and enters your home.
Flashings & Penetrations
Metal flashings around chimneys, plumbing vents, and skylights expand and contract with temperature changes. Over years of Ottawa’s extreme freeze-thaw cycles, the sealants around these flashings can crack or pull away, creating entry points for water.
Mechanical Damage
Heavy snow loads, fallen tree limbs, or even aggressive snow removal (like hacking at ice with a shovel) can crack shingles or puncture membranes.
The Godfrey Roofing Approach to Winter Repairs
When you contact us for a winter roof repair, our process is thorough and safety-focused. We don’t just patch the symptom; we look for the root cause.
- Phase 1: Diagnosis and Safety: Our team arrives equipped for winter conditions. We assess the safety of the site and identify the source of the leak. We distinguish between condensation issues and exterior breaches to ensure we are fixing the right problem.
- Phase 2: Snow and Ice Removal: You cannot repair a roof you cannot see. We carefully remove snow and ice from the affected area. Unlike some contractors who might use axes or hammers that damage shingles, we use specialized techniques to clear the area without harming the roof covering.
- Phase 3: Temporary vs. Permanent Repair: In some cases, a permanent repair (like replacing a large section of shingles) requires warm weather to ensure the adhesive seals properly. In these instances, we install a high-quality temporary patch to stop the leak immediately. This secures your home until spring, when we can return for a permanent restoration. However, many localized repairs, such as fixing flashing or replacing a few damaged tabs, can be completed permanently even in winter using cold-weather modified cements.

Preventing Future Leaks
Once the immediate crisis is resolved, we recommend looking at long-term prevention.
- Attic Inspection: Since ice dams cause many winter leaks, the solution often lies inside your attic. Upgrading insulation and ensuring your soffit vents are not blocked by debris or insulation batts will keep your roof deck cold, preventing the melt-freeze cycle that causes damage.
- Regular Maintenance: Routine inspections in the fall can catch loose flashings and cracked caulking before the snow flies. A small investment in maintenance often saves thousands in emergency repairs.
Frequently Asked Questions About Winter Roof Leaks In Ottawa
Q: Can you replace a roof in the winter?
A: Yes, absolutely. While we prefer dry, warm days, a professional crew can replace a roof in winter. We take special care to keep materials dry and use winter-specific installation methods. If your roof has suffered catastrophic failure, we can secure it.
Q: Will my insurance cover winter roof leaks?
A: Most homeowner insurance policies cover sudden, accidental physical damage (like a tree falling) and the interior water damage resulting from a roof leak. However, they typically do not cover the repair of the roof itself if it is due to age or wear and tear. We can provide detailed documentation of our findings to assist with your claim.
Q: Should I shovel my own roof?
A: We generally advise against it. Roofs are slippery, and you cannot see skylights or vents under the snow. Furthermore, standard shovels can easily crack cold, brittle shingles. Professional Snow & Ice Removal is the safest option for both you and your roof.
