Roof Leak: What to Do (and Avoid) in an Emergency
An active ceiling leak during heavy rain is stressful. The good news: the first steps to take are simple and almost always limit the damage. The bad news: some intuitive reactions make things worse. Here's a clear action plan.
The first 5 minutes
Move everything that can be damaged out from under the leak: furniture, rugs, electronics. If you can't move it, cover with a thick plastic tarp — not a sheet, which holds water and spreads it.
Place a bucket directly under the drip. Put a towel in the bottom to absorb impact (otherwise splashes travel 1-2 metres).
If water is collecting in a ceiling and forming a hanging bulge: pierce the bulge at the centre with a screwdriver and let the water drain into the bucket. Counter-intuitive but essential — held water will eventually blow out the whole ceiling, and then you're replacing the full panel.
The next 30 minutes
Cut power to the affected area at the main panel. Water and electricity don't mix, and a wet ceiling near a light fixture is a real risk.
Document with your phone: photos and a short video of the leak, affected areas, and water collected. If you file an insurance claim, these photos will double your chances of a fast settlement.
Contact your insurer to open a file — even if you're unsure about reimbursement. Simply having a claim open at the time of incident protects your rights.
What to avoid
Don't go on the roof during an active storm. It's the leading cause of serious leak-related accidents: falls, slipping on a wet roof, electrocution if lightning is nearby. The roof can wait for the rain to stop.
Don't nail down a temporary blue tarp into dry adjacent shingles. Tempting, but it creates new holes that need proper repair later, and the tarp comes loose at the first strong gust.
Don't sign any emergency contract with a roofer who shows up at your door 30 minutes after the incident claiming to fix it right now. Real professionals are rarely available within the hour — except in exceptional cases.
When to call an emergency roofer
If the leak fills more than one bucket every 30 minutes during moderate rain: the infiltration area is likely wide and needs fast intervention to limit interior damage.
If water is seeping near an electrical panel, light fixture, or ceiling junction box: serious risk, intervention needed within hours.
If multiple shingles are visibly displaced or torn off (visible from the ground): the urgency is to tarp the area cleanly before the next shower, not necessarily to replace the roof that day.
For minor leaks (a few drops, slightly stained ceiling), you can plan a visit within 48-72 hours after the rain ends. Cheaper, and lets you get a careful repair rather than an emergency tarp.
The repair: targeted or full?
A localized leak on a roof under 12 years old = almost always a targeted repair. Remove a few shingles, redo the flashing, or replace a precise area, done.
A leak on a roof over 18 years old = you have to evaluate whether to repair or plan the replacement soon. A repair costs a fraction of a replacement, but if the roof is in its last year, spending on the repair is wasted money.
Either way: a serious roofer will give you both options with respective costs and expected lifespan, so you can decide.
A leak handled smartly in the first hour costs far less than one ignored. If you need a fast visit in Gatineau or the Outaouais, request a quote by form or phone — we evaluate for free and offer solutions matched to severity.
