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

Why Elsternwick roof cavities overheat
Elsternwick's Edwardian and interwar homes near Rippon Lea were built well before modern roof ventilation standards, so the roof cavity in many of these homes has little way to shed heat or moisture on its own. A whirlybird fixes that passively, using wind movement and the natural rise of hot air to draw it continuously out of the cavity. On period terracotta and slate roofs we flash the install carefully under the tile or slate course so it stays weatherproof and sits sympathetically on an older roof; on concrete tile it's a more straightforward fit. With the suburb's heavy tree canopy keeping many roofs shaded, moisture build-up in the cavity is as much a concern here as summer heat.
Elsternwick's mature tree canopy keeps roof cavities cooler but also damper for longer through winter, so venting here does real work clearing trapped moisture that could otherwise sit against old timber.

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 Elsternwick
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
Elsternwick whirlybird installation — your questions
Yes. We flash it carefully into the slate course so the install is fully weatherproof and doesn't disturb surrounding slates, which matters on Elsternwick's older period roofs.
Yes. On Elsternwick's shaded, tree-covered roofs, clearing trapped moisture from the cavity is just as important as reducing summer heat, since damp roof timber over years can lead to rot.
It depends on your roof's area and pitch, typically two to four turbines for a standard Elsternwick home. We assess the roof rather than quoting a fixed package.
