Whirlybird Installation
in Burnside Heights.
Burnside Heights' brick veneer homes were built with minimal roof ventilation, and with no established tree canopy to shade the estate's open streets, the roof cavity above the ceiling can heat up significantly on a sunny day and hold that heat well into the evening.

Why Burnside Heights roof cavities overheat
Burnside Heights' brick veneer homes were built with minimal roof ventilation, and with no established tree canopy to shade the estate's open streets, the roof cavity above the ceiling can heat up significantly on a sunny day and hold that heat well into the evening. A whirlybird uses wind movement and the natural rise of hot air to continuously exhaust that cavity, cutting the heat load pushing down into the rooms below. On the concrete-tile roofs common here, we lift the tile course, cut a clean penetration, bed the flashing watertight and seat the turbine so it performs properly from day one rather than just looking the part.
With no established tree cover across Burnside Heights' estate streets, roof cavities take on a lot of direct summer heat, so the case for a whirlybird here is mainly about cutting that heat load rather than managing trapped moisture.

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 Burnside Heights
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
Burnside Heights whirlybird installation — your questions
It helps meaningfully with the roof cavity. On open, low-canopy estate streets like these, cavity heat builds up fast in summer, and a whirlybird continuously exhausts that hot air instead of letting it radiate down into the ceiling.
Most homes here need two to four turbines placed high on the roof to move air effectively, depending on the roof's size and layout. We assess the roof rather than fitting a standard number to every house.
Not when it's flashed correctly. We bed and seal the flashing under the tile course during installation, so the roof stays fully weatherproof once the turbine is fitted.
