Roof leak repair that traces water to its source
A stain on your ceiling rarely sits directly below the actual leak. We find where water is really entering and fix that, with photos to prove it.

Why leaks are tricky on Ontario roofs
Water travels along rafters and decking before it shows up as a stain, which means the visible damage is often feet away from the actual entry point. Freeze-thaw cycling makes this worse, opening small gaps in flashing and shingles that widen over successive winters.
Flashing failure tracing
Chimneys, vents, and valleys are common leak points, and we trace water back to these areas rather than assuming the nearest shingle is the cause.
Ice dam related leaks
Backed-up meltwater from ice damming can travel under shingles well past the eave, and we check for this pattern specifically.
Attic-side confirmation
We verify leak paths from inside the attic when possible, giving a clearer picture than exterior inspection alone.
Repair, not just patch
We address the underlying cause, whether that's failed flashing, worn underlayment, or a ventilation issue.
A patched stain doesn't mean a fixed leak
Painting over a ceiling stain or slapping sealant on the nearest shingle often masks the problem temporarily. Without tracing the water's actual path, the same leak tends to reappear, sometimes in a new spot, after the next heavy rain or spring melt.
We repair the entry point, then document it
Our leak repair process starts with tracing, not patching. Once we've confirmed the source, we repair flashing, shingles, or underlayment as needed, and provide photos showing both the problem area and the completed fix.

Roof leak repair questions
Why does my ceiling stain keep coming back?
If the actual entry point wasn't traced and repaired, water can continue finding the same path, especially after freeze-thaw cycles reopen small gaps.
Can you repair a leak without a full roof replacement?
In many cases yes, a targeted flashing or shingle repair resolves the issue without needing a full tear-off.
Do you check the attic during leak repairs?
Yes, attic-side confirmation helps verify we've found the true source before repairing.
How fast can you respond to an active leak?
We prioritize active leak calls and aim to schedule an assessment quickly.
