What is Roof Flashing?
Roof flashing is the protective metal installed around roof joins, edges and penetrations (like chimneys, skylights, and valleys). Its job is simple but critical: to stop water from entering where roofing materials meet.
When flashing fails, water can penetrate your roof structure and cause serious damage inside your home.

ROOF FLASHING FAQ
Roof flashing is the thin metal installed around roof joins, valleys, chimneys, skylights and edges. Its main job is to stop water from entering your roof at weak points. Without proper flashing, even a small gap can cause serious roof leaks and water damage inside your home.
Common signs of leaking flashing include:
Water stains on ceilings or walls
Dripping during heavy rain
Rusted, cracked or lifted flashing visible from outside
Musty smells from hidden roof leaks
If you notice any of these, it’s best to arrange a flashing inspection before the damage spreads.
Not always! In many cases, flashing leaks can be repaired by resealing, re-bedding, or patching problem areas. Full flashing replacement is only required if the metal is badly rusted, cracked or poorly installed. At Kangaroof, we always try to repair first to save you money.
Costs depend on the type of flashing, the size of the leak, and the condition of your roof. Minor resealing may be affordable, while full valley iron replacement costs more. The best way to know is with a free inspection, where we’ll give you an upfront quote with no hidden surprises.
