Flashing Repairs & Upgrades for Leaking Wall Junctions
Wall-to-roof flashing failures are often subtle and slow — leading to hidden rot behind plaster, mould in ceiling cavities, and structural degradation over time. These failures typically result from deteriorated flashing, cement-only bedding, or improper sealing behind wall finishes. We provide expert diagnosis, removal, and replacement of step flashing, apron flashing, and parapet flashings — with a focus on waterproof integration rather than patchwork fixes.
Our flashing upgrades are ideal for homes undergoing rendering, cladding replacement, or roof restoration. We cut and install fresh flashings into wall finishes, seal with compliant backings, and anchor flashing profiles beneath tiles or beneath the upper course of metal roofing — depending on the system. This process ensures moisture cannot penetrate behind the wall or enter the insulation cavity.
Step Flashing for Vertical Wall Intersections
Step flashing is used along sloped roof edges that meet vertical walls. It consists of overlapping metal segments installed between each tile course or under each sheet pan. This staggered flashing system is ideal for directing water downward, preventing infiltration between roof and siding. At Sydney Roofers, we install fully interlocked step flashing using corrosion-resistant Colorbond® or Zincalume®, custom-bent on-site to suit wall spacing and roof profile.
Apron Flashing at Wall Bases, Gables & Dormers
Apron flashing is applied at the bottom edge of vertical walls, dormers, or parapets, where the surface meets a sloping roof. This flashing channels water from the wall directly onto the roof surface and into drainage paths. We fabricate apron flashing to the exact height, length, and pitch of each wall, sealing beneath the cladding and over the roof material with storm-grade sealants and compliant overlaps.
Reflashing After Wall Render, Cladding or Parapet Work
Flashing must often be redone after wall modifications — especially when rendering, recladding, or adjusting insulation. We provide precision re-flashing services that cut into finished walls (where permitted), seal flashing behind top layers, and terminate flashings in chase cuts or wall profiles. This is essential to restore waterproofing integrity and prevent render or cladding damage over time.
Flashing Solutions for Tiled, Metal & Flat Roof Junctions
Each roof system requires a tailored approach. On tiled roofs, we bed flashings beneath ridges and re-point caps as needed. On metal roofing, we fix and seal flashings beneath ribbed panels and secure them under caps. On membrane or flat roofs, we install bonded flashing upstands and seal junctions with compatible waterproof membranes to prevent ponding and seepage at parapet transitions or wall terminations.
At Sydney Roofers, we don’t cut corners when it comes to flashing — especially at the most vulnerable junctions between roof and wall. Our step flashing and roof-to-wall flashing services are designed to protect your property from costly water damage while ensuring a seamless integration with your roofing system. Whether you're building new, retrofitting flashing into old walls, or responding to leaks from poorly installed junctions, we bring precision, compliance, and over 60 years of roofing experience to every job. Contact us today to book an inspection or request a quote for flashing at wall junctions, gables, parapets, and complex vertical connections.
Roof-to-Wall Flashing Systems for New Builds & Renovations
Correctly installed flashing at wall junctions is essential for long-term roof health. In both new construction and major roof renovations, we install flashing at the critical transition where the roof deck meets vertical surfaces such as brickwork, rendered walls, weatherboard cladding, parapets, and dormers. Our systems include step flashing overlapped with wall cladding, apron flashing at lower edges, and sub-flashing behind underlays or sarking.
We assess drainage angles, wall materials, and roof slope to fabricate flashings that provide proper overlap, fall, and sealant compatibility. We also install dry pans and under-tile channels where applicable to prevent backflow and trap water at the correct exit points — particularly in complex or stepped wall details.
Step Flashing & Roof-to-Wall Flashing Installation Sydney – Precision Waterproofing for Wall and Roof Junctions
Roof-to-wall junctions are among the most common failure points in Australian roofs — and one of the leading causes of chronic leaks, internal water damage, and structural decay. At Sydney Roofers, we offer professional installation, upgrade, and replacement of step flashing, apron flashing, and roof-to-wall flashing systems across Sydney. Whether you’re building a new roof, restoring an old one, or repairing water ingress around sidewalls, parapets, or vertical transitions, our solutions are engineered for performance, durability, and full compliance with AS/NZS 3500, NCC codes, and local council requirements.
We work with both tile and metal roofing systems, integrating custom-fabricated flashings to suit each roof’s geometry, pitch, and wall cladding. Our flashing installations are designed to redirect stormwater, accommodate thermal movement, and protect internal wall cavities from moisture intrusion — delivering a watertight finish that lasts for decades.
