About Flashing Penetrations products

Roof penetration flashing needs to suit the opening and the roof covering around it, so the detail should identify how the flashing meets the roof assembly. The Flashing Penetrations page lists Custom Flashings by Freeman Roofing for project-specific requirements.

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

Wall penetration flashing sits within the cladding and wall build-up, where the junction must preserve the route for water to drain out. The listed Eurotect Window Flashing System is for window junctions, while MG100 For Structural Steel | Cavity Flashings by Vanluk Design is a cavity flashing product.

Flashing penetrations on New Zealand projects can involve a service opening, a window edge or a change in the wall cavity. Eurotect Head Flashing is listed for head junctions; its role differs from a flashing formed for a roof opening or a service.

What information belongs on a custom flashing detail?

Show the opening’s location and dimensions, the roof or wall build-up, and the materials the flashing must meet. Include the intended route for water to drain out.

What is a cavity flashing used for?

It is fitted within a wall cavity at a junction or interruption in the wall assembly. The detail should allow water in the cavity to drain to the exterior.

Can a window flashing component seal a service opening?

Use a component for the junction it is designed to serve. A window system and a service seal have different applications, so check the product instructions before specifying either.
