Whirlybird Installation
in Wandong.
Wandong's older township homes, many built before roof ventilation was standard, trap summer heat in the roof cavity with nowhere to escape, and the area's exposure to full sun on open rural-residential blocks further out means that heat load can be significant on hot days.

Why Wandong roof cavities overheat
Wandong's older township homes, many built before roof ventilation was standard, trap summer heat in the roof cavity with nowhere to escape, and the area's exposure to full sun on open rural-residential blocks further out means that heat load can be significant on hot days. A whirlybird uses wind and rising heat to continuously draw hot air out of the cavity, cutting ceiling heat load in the house below. It's a straightforward retrofit on the concrete tile and Colorbond common across Wandong's properties.
Wandong's mix of older township homes and open rural-residential blocks means both under-ventilated original roofs and sun-exposed newer roofs benefit from a whirlybird, just for slightly different reasons.

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 Wandong
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
Wandong whirlybird installation — your questions
Yes — homes built before ventilation was standard often have no way for hot, moist roof cavity air to escape, and a whirlybird gives it a continuous exit point using wind and rising heat.
Yes — many rural-residential Wandong properties have sheds or outbuildings, and we can assess whether ventilation would benefit those roofs as part of the same quote.
It depends on your roof area and cavity volume. We assess your specific roof at the free quote and recommend the right number rather than a one-size-fits-all figure.
