Roof leaks around skylights, vents, or antennae are often caused by worn seals or poor flashing. Our Melbourne-based team specialises in diagnosing and repairing roof penetrations to stop water ingress before it causes internal damage. Whether it’s a leaking skylight, flue pipe, or roof vent, we provide long-lasting repairs that meet VBA standards and stand up to Melbourne’s unpredictable weather.

Skylights and other roof penetrations—like vents, pipes, antennas, and flues—can become weak points if not sealed and maintained properly. Over time, flashing can corrode or shift, seals may crack, and water can start to seep into your roof cavity. Our roof plumbers are trained to repair and reseal all types of roof penetrations, including Velux skylights, ventilation ducts, solar penetrations and more. We make sure every repair complies with the Plumbing Code of Australia and Victorian Building Authority standards, delivering waterproof protection that lasts.
Roof leaks caused by skylights and penetrations are often gradual, making them hard to spot until major damage appears inside your ceiling or walls. Fixing these issues early prevents timber rot, mould, electrical faults and insulation damage. Our team inspects the area thoroughly and applies effective waterproofing solutions—like resealing joints, replacing flashings, or re-flashing with Colorbond or lead-free materials. Whether it’s a residential home or commercial roof, we restore full protection against Melbourne’s rain, wind and hail conditions.

Frequently Asked Questions
Leaks usually occur due to deteriorated flashing, cracked seals, or improper installation. Skylights are prone to collecting debris and pooling water, especially on low-slope roofs. Our team checks for worn sealants, corrosion, and flashing faults, then applies a watertight fix using materials built for Melbourne’s weather.
Yes, in many cases skylight leaks are caused by failed flashing or deteriorated sealant—not the skylight itself. Our team can reseal, re-flash or repair the surrounding area without needing a full replacement. We’ll only recommend a full skylight replacement if the unit is cracked, warped, or no longer structurally sound.
