Roof Flashing & Penetrations
Faulty flashing and poorly sealed penetrations are the leading cause of roof leaks in Sydney homes. We repair, reseal and replace them so water stays outside where it belongs.
Why this work is critical
The most vulnerable points on any roof
Vents, skylights and pipe penetrations are where the roof is deliberately cut open — and where nearly every leak starts.
Vents and whirly birds
Anything cut into the roof breaks the waterproof line. Vents and whirly birds rely entirely on the seal around them.
Skylights and valleys
Skylight surrounds and valley flashings collect and channel large volumes of water — small faults leak heavily.
Pipes and flues
Vent pipes, flues and aerial penetrations shift and perish over time, opening gaps you can't see from the ground.

Done right the first time
Precision workmanship prevents recurring leaks
Most repeat roof leaks we're called to were "fixed" with a bead of silicone. Sealant alone fails within a season or two. We strip back the failed flashing, correct the underlying detail, and install materials rated for the roof type and pitch — so the repair lasts and you're not paying a second tradesperson for the same leak.
Every job is completed to Australian standards, by licensed and insured roof plumbers, and backed by our lifetime workmanship warranty.
