Roof flashing seals the joint between shingles and any wall, chimney, skylight, or vent that penetrates the roof in Collingwood. It's also the number-one source of roof leaks — over 70% of leak calls trace back to failed flashing, not shingles.

Why roof flashing repair matters in Collingwood

The #1 Leak Source

When a homeowner says 'my roof leaks', 7 times out of 10 the shingles are fine and the flashing has failed.

Step Flashing Matters

Continuous flashing bent along a wall fails in years. Step flashing woven between courses of shingles lasts decades.

Skylight & Vent Boots

Rubber vent boots crack in Canadian sun. Replacing them is a 30-minute job that prevents drywall damage.

No call centre, no chasing. Booked in two minutes and got a text when the truck was on the way.

Bundled two services, saved the trip fee
Had the chimney and the dryer vent done on the same visit. Cheaper and half the disruption.

Reliable across three jobs
Used them for a sweep, a dryer vent, and a fireplace service. Same standard every time and the same technician twice, which I appreciated.
