Roof leak repair that starts by finding where water actually gets in
The stain on your ceiling is rarely directly under the leak. We trace water path before we touch a shingle.

Why leak tracing matters more than patching the obvious spot
Water travels along roof decking and rafters before it shows up as a stain, which means the visible damage inside your house is often feet away from the actual entry point. Patch the wrong spot and the leak just finds a new path to the same ceiling stain next season.
Ice damming pushes water uphill
In our climate, ice dams at the eaves can force meltwater backward under shingles, well above where the ice actually formed. This is one of the most common misdiagnosed leaks in the GTA.
Flashing failures rarely announce themselves clearly
A leak near a chimney or skylight is often flashing, not the shingles nearby, even though the shingles get blamed first.
Valley leaks show up far from the valley itself
Water funnels down valleys and can travel along the deck before finding a nail hole or seam to drip through.
Attic insulation can mask or redirect water
Water can travel along insulation before dripping, which throws off the apparent leak location if you're only looking at the ceiling stain.
The 'patch what you can see' repair that doesn't hold
A rushed leak repair targets the visible shingle damage and calls it done. If that's not actually where water is entering, the leak returns after the next rain or thaw, and now there's drywall damage on top of the original roof issue.
Tracing before patching, every time
We follow the water path from the interior stain back to the actual entry point using attic access, deck inspection, and flashing checks. The repair addresses the real cause, and we tell you plainly if what looks like a roof leak is actually a condensation or ventilation issue instead.

Following the water path from inside where access allows.

Repair and verification
Fixing the actual source and checking during the next rain event where possible.

Do you need attic access to trace a leak?
It helps significantly when available, since it lets us follow the water path rather than guessing from outside.
What if it's not actually a roof leak?
We'll tell you if the issue looks like condensation or a ventilation problem instead, rather than repairing a roof that isn't the cause.
Will you patch or fully repair the area?
Depends on what tracing reveals. We scope the actual repair needed, which we explain before starting work.
