Leaks Toronto Roofs Develop More Than Most
Toronto's freeze-thaw winters and lake-effect snow squalls create ice damming conditions that push meltwater back under shingles at the eaves — a leak source that has nothing to do with the roof's overall age. Flat commercial roofs develop their own version at seams, drains, and parapet flashing after repeated freeze cycles work membrane joints loose.
Ice dam related leaks
Water backing up under shingles from ice buildup at the eaves, common in older homes with limited attic ventilation.
Flashing failures
Around chimneys, vents, and skylights — one of the most frequent leak points on any roof type.
Flat roof seam leaks
Membrane seams that separate slightly over repeated freeze-thaw cycles, letting water track in at a single weak point.
Interior tracing
Water often travels along framing before it shows up as a ceiling stain — we trace back to the true source, not just the visible spot.
The Stain on Your Ceiling Isn't Where the Leak Started
Water travels. It can enter at a flashing gap, a lifted shingle, or a membrane seam several feet from where it eventually shows up indoors, tracking along rafters or roof deck before dripping through. Patching drywall or painting over a stain does nothing if the actual entry point above is left unaddressed — the leak simply returns with the next thaw or storm.
We Trace First, Then Repair the Actual Entry Point
Our leak repairs start with tracing water back to its real source, checking flashing, seams, and penetrations methodically rather than guessing. Once we find it, we repair properly and photograph both the source and the completed fix, so you have a record of what was actually wrong and what was done about it.

Roof Leak Repair Questions
How fast can you respond to an active leak?
We prioritize active leaks and aim to schedule an inspection promptly. Email us with your address and details on what you're seeing indoors.
Why does my roof leak only during winter thaws?
This is often ice damming — meltwater refreezing at the eaves and backing up under shingles. It's a common pattern in Toronto and one we specifically check for.
Can a small leak really cause major damage?
Yes. Water tracking along framing and insulation over a winter can lead to saturated materials and mould risk well before it's visible as a ceiling stain.
Do you repair leaks on flat commercial roofs?
Yes, we trace and repair seam, drain, and flashing leaks on flat and low-slope commercial roofing systems.
Will you document the repair for insurance purposes?
Yes, we provide photo documentation of both the leak source and the completed repair.
