You’ve got a leaky roof in Toronto and you’re probably wondering what to do before the next rainfall turns your living room into a wading pool. We will walk you through what causes roof leaks, how to spot them, when to fix them, what repair costs to expect, and what steps you can take now. No fluff. No filler. Just straight-up help from Toronto Roofer.
Is your roof leaking or is it something else?
You see a stain on the ceiling. Maybe there’s a drip. First thought? Roof leak.
But hold on.
Not every ceiling stain means you’ve got a leaky roof. Sometimes it’s a pipe. Other times it’s condensation or old damage that finally showed through.
Still, if you’re seeing:
-
Water stains on the ceiling
-
Musty smells in the attic
-
Paint peeling or drywall bubbling
-
A dripping noise when it rains
…it’s probably time to check the roof.
You don’t need to panic. But ignoring it won’t help.
Common causes of a leaky roof in Toronto
Roof problems in Toronto hit harder because of how brutal winters can be. Snow, ice, and wild temperature swings chew up materials fast.
Aging shingles and wear
If your shingles are over 15 years old, expect issues. Asphalt doesn’t age well in freeze-thaw cycles.
Shingles crack, curl, or blow off.
You’ll start seeing little granules in the gutter. That’s roof material breaking down.
One missing shingle doesn’t sound like a big deal, but water sneaks in fast.
Flashing failures
Flashing is the metal stuff around vents, chimneys, and skylights.
When flashing lifts or rusts, water goes right underneath it.
It’s one of the top causes of leaks near walls or corners.
We’ve fixed hundreds of these at Toronto Roofer. Easy to miss until you get in close.
Ice dams and snow loads
Winter hits hard in the GTA.
Warm air in your attic melts snow on the roof. That water runs down, hits the edge, then freezes again. That’s an ice dam.
Behind that ice, water builds up and pushes under your shingles.
No insulation? Poor ventilation? This happens more.
Skylight or vent problems
Skylights can leak around the edges. Especially if they weren’t installed right.
Sometimes, it’s not a leak. It’s condensation dripping from the inside.
Same deal with vents. Poor seals or cracked boots lead to sneaky leaks.
What happens if you wait too long
You think it’s minor.
Weeks pass. Then you smell mold. Your insulation gets wet. Wood rots. Drywall sags.
Now it’s not a roof repair. It’s a renovation.
We once had a homeowner in East York wait six months on a leak the size of a quarter. It turned into $4,800 in damage. Mold in the attic, new insulation, ceiling repair, repainting.
Leaks don’t fix themselves. Ever.
How to temporarily stop a leak (if you must)
Short-term, these can buy you time:
-
Tarp the area if you can do it safely.
-
Use roofing cement for small cracks or holes.
-
Clear your gutters if snowmelt has nowhere to go.
-
Catch water with buckets and protect furniture below.
But don’t go up there during rain or ice. We’ve seen too many accidents.
Call a professional. At least get advice.
