Roof Leaks & Repairs

Tackling Tough Roof Leaks

For an untrained individual, finding and fixing roof leaks properly can be challenging. At Canberra Water, Gas & Air, our lead tradesmen have solved complex leaks that other companies couldn’t fix. As fully qualified plumbers, we understand precisely how water behaves and moves through different roofing materials. That insight is crucial because many roofers attempt quick fixes that simply divert water elsewhere, often causing further damage and costly repairs.

From our experience repairing roof leaks across Canberra, we’ve seen countless “patch” jobs fail because the root cause wasn’t addressed. Other companies frequently miss hidden pathways -water may track under roofing sheets, flow along purlins, or seep through deteriorated flashings. We go beyond stop-gap solutions: once our repair is complete, we test it thoroughly (unlike many providers) to confirm that the leak is truly resolved.

Our Proven Roof Leak Repair Process

Detailed Leak Diagnosis:

We inspect the entire roof system – including underlays, flashings, ridge caps and gutter connections – to pinpoint exactly where water is entering.

Material-Specific Solutions:

Whether your roof is Colorbond® sheeting, tile or metal, we select appropriate sealants, flashings and repair techniques to match the material and pitch.

Flashings & Seals:

If existing flashings have failed, we fabricate or install new, correctly profiled flashings. We also replace or reseal ridge capping, gutter apron flashings and valley metal to eliminate entry points.

Membrane & Underlayment Repairs:

When underlay or membranes are compromised, we replace damaged sections and ensure overlapping layers maintain proper water flow off the roof.

Post-Repair Testing:

After completing repairs, we simulate rainfall or use water hoses to confirm there are no leaks. This step guarantees a watertight result—so you won’t see water reappear days or weeks later.If you want your roof leak fixed for good, contact Canberra Water, Gas & Air today.
