Roof flashing is one of the most critical—but often overlooked—components of your roofing system. In Toronto, where snow, ice, and rain are frequent, damaged or poorly installed flashing is a leading cause of roof leaks. Understanding what flashing does and when it needs repair can save you from costly interior damage.
What Is Roof Flashing?
Flashing is a thin layer of metal (usually aluminum or galvanized steel) that’s installed around roof edges, chimneys, skylights, dormers, and vent pipes. Its job is to create a waterproof barrier where roofing materials meet vertical surfaces or seams—areas where water typically tries to enter.
When flashing becomes loose, rusted, or improperly sealed, water finds a way in. Even a small gap can lead to significant leaks, especially during Toronto’s wet spring or winter thaw.
Signs Your Flashing Needs Repair
Inside your home, signs include water stains near fireplaces, ceiling corners, or around skylights. On the roof, you may notice lifting or bent metal flashing, missing sealant, or corrosion. If flashing has shifted due to high winds or wasn’t installed correctly, it leaves your home vulnerable.
Routine roof inspections are the best way to catch flashing issues before they lead to major damage.
