Every roof has junction points where two surfaces meet, where a pipe penetrates the sheeting, where a wall rises above the roofline, or where a chimney breaks through the tile plane. These junctions cannot be sealed by roofing material alone. They require roof flashing: purpose-made metal or membrane components that bridge the gap, direct water away from the opening, and maintain a permanently watertight seal through years of thermal movement and weather exposure. Consequently, when roof flashing fails, water enters regardless of how good the tiles or sheeting surrounding it are.
At All Your Roofing, our roofing and flashing service covers every flashing type across every roof system. We install new flashing for a roof on new builds, extensions, and re-roofs. We carry out roof flashing repair on failed or deteriorated existing systems. Additionally, we replace sealant-only patches, the most common form of DIY flashing repair, with correctly lapped and mechanically fixed metal or membrane systems that are designed to last decades rather than years. Therefore, every flashing job we complete addresses the cause of the water entry rather than coating over it.
Failed roof flashing is one of the most common sources of emergency roof leaks. Therefore, our emergency response team is available 24 hours a day, 7 days a week for active water ingress caused by flashing failure
Not all roof flashing failures are visible during a standard inspection. Stepped chimney flashing failures and concealed valley flashing separations often allow water to travel several meters before appearing inside.
Every roof flashing installation and repair is backed by a full 10-year transferable workmanship warranty. Moreover, where we supply flashing materials, those materials carry their own manufacturer warranties for corrosion resistance and weathering performance, typically 25 to 50 years for quality lead.
Waterproof flashing is not a one-size-fits-all product. Lead flashing is the traditional choice for chimney and masonry abutments it is soft, malleable, and durable for decades.
Every technician is licensed under QBCC, NSW Fair Trading, and all relevant state equivalents. Furthermore, all team members carry Working at Heights certifications and are covered by $20M public liability insurance.
Roof flashing repair costs should be clear before any work begins. You receive a firm written quote after the inspection, itemised by flashing type, material specification, and labour. That price is locked in for 30 days.

Industry data consistently shows that the majority of roof leaks originate at flashing junctions rather than through tiles or roofing sheets. However, because water travels along roof framing before dripping through at a ceiling low point, the leak is often attributed to a tile or sheet fault that is not actually the entry point.
Chimney flashing failures and skylight flashing separations are particularly damaging because they typically sit above valuable interior spaces — living rooms, master bedrooms, and home offices
Chimney flashing does not only protect the roof surface. It also protects the chimney itself. Water entering at the flashing junction tracks down between the chimney masonry and the roof structure
A failed roof flashing repair typically costs between $300 and $1,500 depending on the flashing type, location, and material. In contrast, the internal damage that a persistent flashing leak causes, including ceiling replacement, insulation removal, structural timber treatment, and flooring repair regularly exceeds $10,000 to $30,000
Chimney flashing is one of the most technically complex roofing and flashing applications because it involves multiple intersecting components. A complete chimney flashing system includes step flashing on the upslope sides, counter flashing embedded into the mortar joints of the chimney masonry, apron flashing at the downslope base, and a saddle or cricket flashing at the back of the chimney on steeper pitches to divert water away from the chimney-to-roof junction.
Skylights, plumbing vents, solar conduits, exhaust fans, and whirlybird bases all require correctly installed waterproof flashing to maintain the integrity of the roof surface. However, each penetration type has different movement and dimensional requirements that affect the flashing design. A fixed skylight flashing behaves differently to a plumbing pipe collar, which moves with the house frame independently of the roof sheeting.
Valley flashing is the channel that runs along the internal angle between two roof planes. It carries the highest water volume of any element on the roof surface and is therefore the most demanding flashing location in terms of material performance and installation quality. For tile roofs, valley flashing is typically formed in coloured metal that is concealed beneath the tile ends. For metal roofing, valley flashing is formed from the same Colorbond sheeting as the roof but in a deeper, purpose-formed profile.
Our flashing for a roof abutment system uses mechanically fixed step flashing embedded at every tile course or sheet lap, with continuous counter flashing embedded into the wall face at a height sufficient to prevent wind-driven water intrusion. Furthermore, where walls are already finished and cannot be re-raked for embedded flashing, we use purpose-made surface-fixed systems with factory-formed cover plates that allow proper lap without relying on sealant alone. As a result, every abutment junction we flash is permanently weathertight regardless of the existing wall construction method.
Roof flashing is the collective term for the metal or membrane components used to seal junctions, transitions, and penetrations on a roof surface. It matters because these are the points where water is most likely to enter a building
The lifespan of roof flashing depends on the material used and the quality of the original installation. Lead flashing installed correctly at a chimney or masonry abutment typically lasts 50 to 70 years.
This is the most common misdiagnosis in residential roofing. In most cases, a leaking chimney is not a tile problem. It is a chimney flashing failure. Water enters at the junction between the chimney masonry and the roof surface, tracks down the back of the chimney or along the chimney sides, and drips through at ceiling level.
Several materials are used for roof flashing depending on the application, roof type, and local conditions. Lead is the traditional and most durable option for chimney flashing and masonry abutments — it is soft, malleable, and extremely long-lived. Colorbond and aluminium are used for valley flashing and penetration flashings on metal and tile roofs.
Roof flashing repair costs depend on the flashing type, location, access requirements, and the material needed. Furthermore, roof flashing costs in multi-storey or difficult-access situations attract a height and access premium.
Minor sealant touch-ups on accessible flashings can be carried out by a confident homeowner. However, correct roof flashing repair particularly chimney flashing replacement and valley re-flashing, requires licensed roofing tradespeople with the correct materials, tools, and technique
The most reliable indicator of a roof flashing failure is a recurring internal leak that does not respond to tile or sheet repairs. Additionally, visual signs to look for from the ground include lifted or bent metal at roof junctions, visible separation between the flashing edge and the masonry or wall surface.
In most cases, roof flashing repair and replacement does not require council approval. It is classified as routine maintenance under the building codes in most Australian states and territories.
