Roof Flashing Replacement for Leaks, Rust & Non-Compliant Installs
Older flashing systems can deteriorate over time due to rust, thermal movement, storm damage, or previous poor workmanship. When flashing becomes cracked, corroded, or detached, it allows moisture to penetrate under tiles, metal sheets, or wall claddings — leading to hidden leaks, internal water damage, mould, and roof timber rot. Our flashing replacement service includes complete removal of failed flashing profiles, inspection of surrounding substrates, and installation of new flashing with upgraded sealants and weatherproofing techniques.
We also replace non-compliant flashing systems on older homes or renovation projects that no longer meet Australian building code standards. Where past flashing work has used cement fills or thin galvanised sheets, we upgrade to high-performance flashing using Colorbond®, Zincalume®, or powder-coated aluminium — fabricated to precise dimensions for a watertight finish.
Precision Flashing for Valleys, Walls, Parapets & Roof Edges
Each area of the roof has unique waterproofing needs. We fabricate flashing solutions that provide targeted protection at internal roof valleys, roof-to-wall junctions, parapets, gables, and eaves. These custom-fitted profiles direct water away from vulnerable joints and prevent pooling, seepage, and internal moisture buildup. Whether working with complex multi-facet designs or simple skillion roofs, our team ensures every detail is installed to exact specifications.
Flashing Integration with Tile, Metal & Flat Roof Systems
No two roof types require the same flashing strategy. We adapt our methods to suit terracotta and concrete tiles, corrugated and standing seam metal roofs, as well as membrane-sealed flat roof systems. This includes under-tile pans, expansion-compatible sealants, proper overlapping angles, and the use of breathable or bonded membranes where needed. By tailoring installation to the roof structure, we ensure long-term protection from rain, wind pressure, and thermal stress.
Premium Flashing Materials for Sydney’s Harsh Conditions
We install flashing made from materials that meet the demands of Sydney’s coastal climate, high rainfall, and fluctuating temperatures. Our flashing systems are fabricated from genuine Colorbond® steel, Zincalume®, or UV-stabilised aluminium, ensuring resistance to corrosion, warping, and UV degradation. All flashings are installed with manufacturer-approved fasteners and sealants to ensure warranty compliance and structural reliability.
Certified Workmanship & Full Building Code Compliance
Every flashing installation and replacement we carry out is completed by licensed roofing professionals and fully documented for compliance with Australian Standards, NCC waterproofing codes, and local council requirements. We ensure correct flashing placement, secure fixing, minimum overlap distances, and weathertight integration with other roof components. All work is backed by warranty and supported with optional compliance certificates and photographic reporting for builders, strata managers, and private homeowners.

New Flashing Installation for All Roof Types and Designs
Installing flashing correctly from the start is essential for the long-term performance of your roofing system. Flashing acts as a critical barrier between your roof surface and potential entry points — including valleys, roof-to-wall connections, parapets, gable ends, chimneys, vents, and skylights. Our team works alongside builders, architects, and homeowners during the construction or renovation process to design and install flashing systems that support proper water runoff, prevent backflow, and integrate seamlessly with both traditional and modern roof materials.
