Wall penetration flashing protects the junction where a service passes through cladding. Exposure to wind-driven rain varies across Australia, so the junction detail needs to suit the site as well as the cladding system. Profiles such as the listed 40mm Flat Back Flashing RDFB40 need to be matched to the specified junction rather than treated as a universal seal for an opening.

Flashing penetrations are a vital part of reroofing a home or creating a new piercing in the roof. Sealing around any openings, from chimneys to skylights and solar panels, prevents leaks and helps with overall water management. At ArchiPro, we offer cavity flashings, cladding penetrations, and everything you need to upgrade the roof performance.

Flashing Penetrations

Details for flashing penetrations also include window junctions. Sill Tray 87mm RDST87 and Sill Tray Stop End (5 Pairs) RDSE are listed as separate components, making the connection between the tray and its end closures an important part of the installation detail. End closures keep collected water from escaping into the jamb, while the tray’s outward drainage route must remain clear.

Can cladding profiles be used as roof penetration flashing?

A wall profile is not a substitute for a detail designed for the roof covering. Choose roof pipe penetration flashing to suit the pipe’s outside diameter and operating temperature, using the roofing system’s specified detail.

How does tile roof penetration flashing manage water?

Its junction must shed water over the tiles without disrupting their laps. By contrast, flat roof penetration flashing needs to connect to the roof’s specified waterproofing system.

What matters when detailing conduit penetration flashing?

Measure the conduit’s outside diameter rather than relying on its nominal trade size. As with pipe penetration flashing, the seal needs to suit the service material and allow for movement.
