Why Braeside roof cavities overheat
Braeside's original 1950s and 1960s homes were built well before modern roof ventilation became standard, so the roof cavity above the ceiling often traps summer heat with nowhere to go. A whirlybird uses wind movement and rising heat to continuously draw that hot, stale air out, easing the load on ceilings and any air conditioning below. On the concrete-tile roofs common here we lift a course of tiles, cut a clean penetration, bed the flashing so it stays watertight, and seat the turbine securely. For homes closer to Braeside Park's tree cover, the extra ventilation also helps clear trapped moisture that can otherwise sit in the roof space.
Braeside's older, unventilated roof cavities heat up hard through summer, and on the shadier blocks near Braeside Park a whirlybird also helps shift the trapped moisture that builds up under heavier tree cover.

The process
How we install a whirlybird
2
Position for airflow
Vents go high on the roof where the hottest air collects, balanced with the eave intake so air can actually move through.
3
Cut & flash
On a tiled roof we lift the tiles, cut a neat penetration, and bed the flashing so it is fully weatherproof.
4
Seat & seal
The turbine is seated in the flashing collar and the tiles are reinstated over the apron, leaving a clean, leak-free finish.
Roof types in Braeside
Installation differs by roof: on tiled roofs we cut and flash the penetration under the tile course, while on metal roofs the vent is flashed directly into the sheeting. Both need the flashing done properly — a rushed vent install is a classic future leak.
Our standard
Installations are carried out by an insured team and the workmanship is backed by a 7-Year Workmanship Guarantee and a 10-Year Dulux Acratex Material Warranty.

What Melbourne homeowners say
Braeside whirlybird installation — your questions
It won't replace air conditioning, but it continuously vents hot, trapped air from the roof cavity, which reduces the heat load pushing down into the ceiling and takes pressure off cooling on hot days.
Many do. Homes built in the 1950s and 1960s here predate modern ventilation standards, so the roof cavity can trap significant heat and moisture with no way to escape until a whirlybird is fitted.
Not when it's flashed correctly. We lift the tile course, bed the flashing watertight under it, and seat the turbine securely, which is the detail that keeps the roof leak-free long term.
