A roof leak is one of the few home problems where minutes matter. Water travels fast, spreads through insulation and drywall, and turns a small entry point into a ceiling replacement if it isn’t contained. This guide walks through exactly what to do in the first minutes, what not to do, how fast help can reach you in the Gatineau–Ottawa region, and what actually causes most sudden leaks here so you can stop the next one before it starts.
What should I do in the first ten minutes of a roof leak?
Contain the water and protect people and property — in that order. The faster you limit the spread, the less you pay to repair afterward.
- Move furniture, electronics, rugs, and valuables away from the wet area.
- Place a bucket, bin, or container directly under the active drip.
- If the ceiling is sagging or bulging with trapped water, puncture the lowest point of the bulge with a screwdriver to drain it in a controlled way into a bucket. A single controlled hole prevents a sudden, wider ceiling collapse.
- Lay down towels to soak up standing water and protect flooring and subfloor.
- Photograph everything — the ceiling, the walls, the floor, and any damaged belongings — for your insurance claim.
- Call a licensed roofer. Cossette Roofing dispatches emergency crews 24/7 at 819-777-7177.
These steps buy you time. They don’t fix the roof, and they aren’t meant to — the goal is to keep water out of your belongings and structure until a professional finds and seals the source.
Should I go up on the roof myself to stop the leak?
No. Do not climb onto a wet, iced, snow-covered, or storm-damaged roof under any circumstances. Wet shingles and membrane are extremely slippery, and a roof that is already failing may not safely hold your weight. Every year, DIY roof access during storms leads to serious falls. The safe division of labour during a leak is simple: you handle containment inside, and a roofer with fall protection and proper equipment handles anything at roof level. Cossette’s trained team is equipped to work safely on wet and damaged roofs; a homeowner on a ladder in the rain is not.
How fast can a roofer actually respond in Gatineau and Ottawa?
Cossette Roofing provides 24/7 emergency roofing service across Gatineau, Ottawa, Hull, Aylmer, and the entire Outaouais region — 365 days a year, including holidays. The emergency line at 819-777-7177 is answered around the clock, not routed to voicemail.
The emergency situations Cossette responds to include:
- Water infiltration through the roof or ceiling
- Storm and wind damage, including lifted or missing shingles
- Ice dams forming at the roof edge in winter
- Snow overload on the roof structure
- Fallen trees or debris on the roof
When a full permanent repair can’t happen immediately — because of weather, time of day, or the scope of damage — Cossette can apply emergency temporary waterproofing to seal the entry point and protect the building. That stabilizes the situation and prevents further interior damage until the permanent repair is scheduled and completed.
What causes most sudden roof leaks in the Outaouais and Ottawa?
In this climate, a handful of causes account for the majority of emergency calls. Knowing them helps you understand what the roofer is looking for and how to prevent a repeat.
- Ice dams. In winter, heat escaping into the attic melts snow on the roof, which refreezes at the cold eaves and forms a dam. Water pools behind it and backs up under the shingles. Proper attic ventilation is the long-term fix, and Cossette inspects and corrects ventilation as part of its work.
- Wind-lifted or missing shingles. A storm can lift or tear shingles, exposing the underlayment and deck to water. This is one of the most common post-storm emergencies.
- Failed flashing and caulking. The seals around chimneys, plumbing vents, and skylights degrade over time. When they fail, water enters at the joint even though the shingles look intact.
- Blocked or damaged flat-roof drainage. On flat and low-slope roofs, standing water from blocked drains eventually finds a weak point in the membrane.
A professional roofer diagnoses the true source before repairing. Patching the visible drip without finding the actual entry point almost always means the leak returns after the next rain or thaw.
How does Cossette handle a roof leak from the first call?
Cossette follows a clear response path. When you call 819-777-7177, the team gathers the essentials — your address, when the leak started, where water is entering, and whether there’s active infiltration or ceiling bulging — and dispatches accordingly. On arrival, a roofer locates the entry point, applies emergency temporary waterproofing if a full repair can’t be completed on the spot, and then provides a plan and written estimate for the permanent repair. Because Cossette is RBQ-licensed (License 5697-7788-01), BBB-accredited, and carries full liability insurance, the emergency work and the permanent repair are both handled by trained, insured professionals.
