Roof Vent and Pipe Flashing Repairs & Replacements

Exhaust pipes, gas flues, whirlybirds, solar vents, and antenna mounts all require precise flashing to prevent water ingress. Pipe boots, silicone seals, and lead-based flashings degrade over time due to UV exposure and movement. When that happens, even the smallest vent can lead to significant internal water damage. At Sydney Roofers, we replace degraded vent flashings with durable, UV-stable systems matched to your roof material. For tiled roofs, we embed new flashings below surrounding tiles and reseal with flexible compounds. For metal roofs, we install apron-sealed flashings or retrofit pipe boots with watertight collars and corrosion-proof fixings.

Repairing Leaks Around Chimney Bases and Flues

Leaking chimneys are often caused by cracked lead flashing, separated mortar joints, or blocked weep paths. We assess the base of the chimney, remove failed flashing, and install custom-fabricated replacements that wrap securely around corners and transitions. We also ensure proper counterflashing, where applicable, to direct water away from vulnerable bedding points.

Replacing Damaged Pipe Boots and Vent Flashings

Vent pipe boots deteriorate from sun exposure and movement, especially when installed with low-grade materials or silicone-only seals. We replace rubber or lead vent boots with reinforced flashing collars, reseal mounting points, and install flexible storm collars that withstand thermal cycling and roof expansion.

Flashing Integration with Tiled & Metal Roofs

Different roof materials require different flashing methods. On tiled roofs, we remove and lift surrounding tiles to install flashing underneath the tile course, bedding and re-pointing as needed. On metal roofs, we install apron and riser flashings with concealed fasteners, ensuring slope-aligned drainage and storm resistance. Our installations protect against wind uplift, ponding, and backflow into underlays or insulation.

Chimney Flashing Upgrades During Re-Roofing or Restorations

When re-roofing or restoring older homes, it’s critical to upgrade chimney and vent flashing to meet modern standards. We fabricate new flashing profiles to match roof pitch, chimney width, and material transitions — including render-cut or brick-reveal flashing. Our team also addresses structural damage around old chimneys and ensures proper sealing between masonry and metal surfaces to eliminate weak points.

Sydney Roofers delivers professional chimney and vent flashing services designed to protect your roof from water ingress, internal damage, and long-term deterioration. Whether you're building new, repairing a leak, or upgrading as part of a re-roofing project, our team brings experience, precision, and fully compliant techniques to every job. Trust us to seal the most vulnerable parts of your roof — and keep your home safe, dry, and structurally sound.

Chimney Flashing Solutions for Brick, Rendered & Metal Chimneys

Water can easily find its way into your roof cavity through poorly sealed chimney bases. Over time, movement in brickwork, crumbling mortar, thermal expansion, and improper flashing angles lead to separation and leakage. Our chimney flashing services are designed to create a watertight envelope around the base of your chimney, integrating apron flashing at the downslope and step flashing along the sides. For new roofs, we install flashing during the build to create a permanent seal. For existing homes, we inspect, remove, and upgrade damaged or outdated flashing with custom-bent Colorbond® or Zincalume® to suit both the chimney and the roof profile.
