Commercial roof flashing repair in Markham covers restaurants, retail, condo boards, and property management companies. WSIB, insurance certificates, and formal quotes provided. Roof flashing seals the joint between shingles and any wall, chimney, skylight, or vent that penetrates the roof in Markham. It's also the number-one source of roof leaks — over 70% of leak calls trace back to failed flashing, not shingles.

Why commercial roof flashing repair in markham matters in Markham

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.
