First, take a breath - then triage
A leak feels like an emergency the moment you see water on the ceiling, but most leaks are not. The first ten minutes are about protecting your home and your safety, not the roof itself - the roof can almost always wait for daylight, dry weather, and a real roofer. What you need to know first is how fast you have to move. Answer the questions below and the tool will tell you.

What not to do
A few well-meant reactions make a leak worse, cost you money, or put you in the hospital. Skip these:
Climbing onto a wet or steep roof to "just take a look" - falls cause far more harm than one night of leaking ever will.
Going up during wind, rain, or lightning. Any temporary cover can wait until conditions are safe.
Nailing a tarp down yourself - done wrong it adds holes, can make the damage worse, and may complicate an insurance claim.
Ignoring a small stain because it stopped. The water found a path; it will be back in the next rain, and damage builds the whole time.
Cleaning up and tossing everything before you photograph it. Your insurer needs to see the damage as it happened.
Tarping is a job for a pro here
On the wet coast, the roof is slick more often than not, and most homes are too steep to be safe. If the leak genuinely needs covering before a repair, that is a call-out for a roofer with fall gear - not a ladder-and-tarp Saturday. From inside, your job is simply to catch the water and document it.
Find what is causing it
Where the water shows up inside is a strong clue to where it is getting in - and the inside spot is often nowhere near the actual hole, because water travels along beams and decking before it drips. Pick the description that matches what you are seeing and you will get the most likely cause, whether it is a quick fix or a roofer call, and a BC-specific note.

How fast a leak does real damage
This is why "I will deal with it later" gets expensive. Water does not wait, and BC’s damp air means things dry slowly once they are wet. Here is the timeline restoration crews see again and again:
- 1Within 24-48 hoursMoisture soaks into drywall, insulation, and wood, and mold spores begin to form. This is the window where drying things out actually prevents the problem.
- 2Within 3-5 daysMold spreads, wood starts to soften, and water near wiring can short out circuits.
- 3Within 1-2 weeksCeiling joists and rafters begin to warp, indoor air gets unhealthy, and repair costs can double or triple.
- 4Past 2 weeksYou are into serious rot, possible roof-deck damage, and a job that is now structural rather than cosmetic.
The 48-hour rule
Mold can take hold within two days, so the goal after any leak is to get the area dry fast - fans, a dehumidifier, open the space up. Even if you cannot fix the roof yet, drying the inside buys you time and saves the drywall.
What a repair costs in Metro Vancouver
Most leak repairs are far cheaper than people fear - the expensive outcomes come from waiting, not from the fix. Pick the type of repair below for a realistic 2026 Lower Mainland range. Remember our labour runs higher than the national average, so treat out-of-province numbers as a floor.
What will the repair cost?

Typical range
$300-$1,500
A typical Metro Vancouver repair lands between $400 and $1,800, averaging around $1,100. Emergency or after-hours call-outs cost more, and a repair on a roof that is already near end of life is rarely worth it - get a replacement quote to compare.
Will insurance cover it?
In BC, the deciding question is almost never how bad the damage is - it is how the leak started. Home insurance is built to cover sudden and accidental events, not slow decline. Your adjuster will look at the cause first.
| Usually covered | Usually not covered | |
|---|---|---|
| Cause | A sudden event - windstorm, a branch through the roof, shingles torn off in a storm | Wear and tear, age, or a slow leak that built up over months |
| How it reads | Accidental and dateable to an event | Gradual deterioration or deferred maintenance |
| What helps | Photos, the date, and a record of a maintained roof | Nothing - neglect is the one thing policies exclude |
Document like it might be a claim
Photograph the damage right away, note the date and what the weather was doing, and keep any record of past roof maintenance. If the leak traces to a storm, that paperwork is the difference between a paid claim and a denied one. When in doubt, call your insurer - asking does not start a claim.
Why BC roofs leak (and one myth to ignore)
The coast is one of the hardest climates in Canada on a roof. The Lower Mainland sees well over 1,500 mm of rain a year, and parts of the North Shore far more, so a roof here stays wet far longer than one on the Prairies. That constant dampness drives the leaks we see most:
The usual coastal culprits
- Moss and trapped moistureOur damp shade grows moss fast. It lifts shingles and holds water against them, speeding up decay until a leak forms.
- Pooling on flat and low-slope roofsCommon on modern BC homes. When a membrane seam cracks, heavy rain finds it immediately.
- Failed flashing and worn vent bootsYears of rain and UV crack the seals around chimneys, skylights, and pipes - the entry point for a huge share of leaks.
- Clogged guttersFir needles and leaves back water up under the roof edge. On the coast this needs clearing at least twice a year.
Ignore the ice-dam advice
Most roof-leak guides online are American and spend half the article on ice dams - snow melting and refreezing at the eaves. In mild, rainy Metro Vancouver that is rarely the issue. Ice dams matter in the Interior and cold-snap winters, not on the coast, so do not let a US blog send you chasing a problem you probably do not have.

What should I do the moment I find a roof leak?
Protect people and property first. If water is anywhere near lights, outlets, or the panel, cut power to that area at the breaker. Move valuables out of the way, put a bucket under the drip with towels around it, and if the ceiling is bulging, drain it on purpose by poking a small hole in the center of the bubble over a bucket. Then photograph everything for insurance. Leave the roof itself until conditions are safe or a roofer can get there.
Is a roof leak an emergency?
It is an emergency if water is near electricity, the ceiling is bulging or sagging, or water is pouring in fast - those need action in minutes. A stain or a slow drip is not a same-minute emergency, but it is not something to ignore either: mold can begin within 24 to 48 hours, so it still needs attention within days.
How long can I leave a roof leak before it causes real damage?
Not long. Mold spores can start forming within 24 to 48 hours, wood begins to soften within a few days, and within one to two weeks structural elements warp and repair costs can double or triple. BC’s damp climate makes everything dry slower, so the safe answer is to dry the area out immediately and get the leak addressed within days, not weeks.
How much does it cost to fix a roof leak in Vancouver?
Most leak repairs in Metro Vancouver run between about $400 and $1,800, averaging around $1,100, before GST. A few shingles or a cracked vent boot can be $150-$500; flashing repairs around a chimney or skylight run $300-$1,500; multiple problem areas at once can reach $2,500 or more. Emergency call-outs cost more, and patching a roof that is already worn out is rarely worth it.
Does home insurance cover a roof leak in BC?
It depends on the cause. Insurance generally covers sudden and accidental damage - a windstorm, a fallen branch, shingles torn off in a storm. It generally does not cover leaks from wear and tear, age, or deferred maintenance. Adjusters look at how the leak started, so photograph the damage, note the date and weather, and keep records of roof maintenance to support a claim.
Should I get on the roof and tarp it myself?
Usually no. On the wet coast roofs are slick and often steep, and a fall is far more dangerous than the leak. Never go up in wind, rain, or lightning. From inside, focus on catching the water and documenting it; if the roof genuinely needs covering before repair, hire a roofer with proper fall protection rather than doing it yourself.
