Kealba's original brick veneer homes were built well before roof ventilation was standard, so the ceiling cavity beneath that 1970s or 80s concrete tile roof traps summer heat and radiates it back down into the living areas overnight.

Why Kealba roof cavities overheat
Kealba's original brick veneer homes were built well before roof ventilation was standard, so the ceiling cavity beneath that 1970s or 80s concrete tile roof traps summer heat and radiates it back down into the living areas overnight. A whirlybird continuously exhausts that trapped air using wind movement and the natural rise of hot air, with no electricity required to run it. Fitting one means lifting the tile course, cutting a clean penetration and bedding the flashing so it's fully watertight, taking care around tiles and mortar that have had four decades to age.
Kealba's original pre-ventilation-era homes trap summer heat in the roof cavity just as much as anywhere else in Melbourne's west, and with many roofs now decades old, careful handling of aged tiles matters during installation.

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 Kealba
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
Kealba whirlybird installation — your questions
Yes, by continuously drawing hot air out of the roof cavity rather than letting it build up and radiate down through the ceiling overnight, which is especially noticeable in Kealba's original homes without other ceiling ventilation.
Yes, though we take extra care lifting tiles on a roof this age, since decades-old tiles and mortar are more brittle than newer stock. We check the surrounding area and bed the flashing properly before finishing the install.
Most standard homes here need two to three turbines, though it depends on the actual roof area and pitch. We measure your specific roof before recommending a number rather than using a fixed figure.
