We look at roof size, pitch and existing airflow to work out how many vents you actually need — no over-selling.

Whirlybird Installation
in Glen Huntly.
Glen Huntly's interwar bungalows and 1960s-70s brick flats were both built well before roof ventilation was standard, so their roof cavities tend to hold onto heat through summer evenings and trap moisture over winter, especially on the more shaded blocks under the suburb's established street trees.

Why Glen Huntly roof cavities overheat
Glen Huntly's interwar bungalows and 1960s-70s brick flats were both built well before roof ventilation was standard, so their roof cavities tend to hold onto heat through summer evenings and trap moisture over winter, especially on the more shaded blocks under the suburb's established street trees. A whirlybird uses wind and rising heat to draw that stale air out continuously rather than letting it sit under the terracotta or concrete tile. On period terracotta roofs we flash the turbine in carefully to suit the existing tile course; on newer concrete tile or Colorbond homes it's a more straightforward fitting. Either way, venting the cavity eases the heat load upstairs and helps stop condensation building up in the roof timbers.
Between Glen Huntly's older, pre-ventilation homes and a moderate tree canopy that keeps some roofs shaded and damp, a whirlybird's constant airflow helps with both the summer heat load and the moisture that builds up in a poorly vented cavity.

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 Glen Huntly
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
Glen Huntly whirlybird installation — your questions
Most homes need two to four turbines set high on the roof for effective airflow, and we size that to your roof's area and pitch rather than fitting a standard package regardless of the home's age.
Yes, we simply take more care with the flashing detail. Period terracotta on Glen Huntly's interwar bungalows needs the turbine bedded into the existing tile course so the install stays weatherproof and sympathetic to the roof.
It should. Continuous airflow from a whirlybird helps clear the moisture that can build up in a poorly vented cavity under Glen Huntly's more shaded, tree-lined streets, reducing the risk of condensation in the timbers.
