Flashing Leaks Are One of Melbourne’s Most Common Roof Problems
Flashing is meant to keep water out at junctions, edges and penetrations. When it fails, water travels underneath roofing materials and causes structural damage, mould, water stains and ongoing roof leaks.
This is why flashing repairs are essential, and why an expert roof plumber should handle the leak detection, not temporary silicone patches.
Signs Your Roof Flashings Need Repair
If you’re seeing any of these, flashing failure is likely. Not sure? Our experts can perform detailed leak detection.

Internal Water Stains
Water stains on ceilings or high on internal walls are classic signs of flashing failure.

Leaks Near Junctions
Drips during heavy rain near chimneys, skylights or vent pipes usually indicate a failed seal.

Visible Metal Damage
Rusted, lifting or loose metal flashing sections that you can see from the ground or roof.

Moisture & Mould
Moisture or mould growth near junctions suggests hidden flashing leaks are present.

Hidden Water Tracking
Water tracking inside even when tiles look fine often points to a compromised flashing seal.

Failed Past Repairs
The same leak returned after previous silicone patches or temporary fixes were applied.
Not sure if the flashings are to blame?
Our expert roof plumbers can perform roof inspection and show you exactly what’s going on.
Seeing water stains or a leaking roof near a junction?
Water traveling through failed flashing can damage timber frames, insulation, and electrical systems long before you see a drip on the ceilings
Common Flashing Issues We Repair
Different roofing surfaces fail in different ways. We repair all major flashing problems across Melbourne.

Chimney Flashings
Rust, movement and poor installation can cause major internal water damage. We reseal or replace chimney collars and apron flashings.

Wall & Roof Junctions
Loose apron flashing or failed step flashing where roofing materials meet vertical walls. We restore the watertight junction.

Skylight Flashings
Perished flashing kits or incorrect installation. We fix wind-driven rain leaks around all skylight frames.

Penetration Flashings
Failed vent boots or gaps around pipes and exhaust penetrations. We install high-quality Dektite seals.

Valley Flashings
Rusted metal, blockages or incorrect fall causing pooling, overflow and hidden leaks.
Even a small flashing failure can lead to a major leaking roof. Explore our Roof Leak Repairs for full diagnostic options.
Why Flashing Fails
Most flashing issues come down to poor installation, ageing materials or weather exposure. The most common causes include:
- Ageing metal or pre-painted steel breaking down from years of exposure
- Incorrect installation or using the wrong roof flashing types for the roof
- Wind uplift and weather damage, especially during heavy Melbourne storms
- Loose fixings on tile roofs or heritage roofs that create gaps for water entry
- Blocked valleys or roof plumbing problems causing overflow into junctions
- Temporary silicone patches used instead of proper flashing installation
Once the watertight seal is lost, water can travel far from the original failure point — leading to leaks that seem unrelated to the actual flashing issue.
