Keon Park's post-war brick veneer homes were built with minimal roof ventilation, so the roof cavity in most of these houses has little way to shed built-up heat in summer or condensation in winter on its own.

Why Keon Park roof cavities overheat
Keon Park's post-war brick veneer homes were built with minimal roof ventilation, so the roof cavity in most of these houses has little way to shed built-up heat in summer or condensation in winter on its own. A whirlybird fixes that passively, using wind and rising heat to continuously draw stale air out of the cavity with no power required. On the concrete and terracotta tile roofs common across the suburb, we flash the turbine in under the tile course so the install stays fully weatherproof. With only moderate tree cover here, the main benefit for most homes is easing the summer heat load radiating down into the ceiling.
Keon Park's open brick veneer streets get solid summer sun on the roof, so venting the cavity makes a real difference to how the house holds heat into the evening, especially on the north and west-facing pitches.

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 Keon Park
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
Keon Park whirlybird installation — your questions
Most standard brick veneer homes need two to four turbines, based on the roof's total area and pitch. We assess your roof rather than quoting a fixed number for every home.
Yes. It reduces the heat trapped in the roof cavity that would otherwise radiate down into the ceiling, which takes pressure off your air conditioner on hot Keon Park afternoons.
No. It's a straightforward roof-top fit that typically takes a few hours, and once installed a whirlybird runs silently on wind movement with no ongoing noise or power draw.
