Glenferrie South's period terraces and villas were built long before roof ventilation was standard, and under the heavy street-tree canopy that shades this pocket, the roof cavity stays damp for longer than it would on a sun-exposed roof.

Why Glenferrie South roof cavities overheat
Glenferrie South's period terraces and villas were built long before roof ventilation was standard, and under the heavy street-tree canopy that shades this pocket, the roof cavity stays damp for longer than it would on a sun-exposed roof. That trapped moisture works against old timber roof framing over time. A whirlybird uses wind movement and rising heat to continuously exhaust the cavity, keeping air moving rather than sitting still under the canopy. On the steep-pitched terracotta and slate roofs common here, we lift the tile or slate course carefully, cut a clean penetration, bed the flashing watertight and seat the turbine so the period roofing isn't compromised.
Glenferrie South's heavy canopy and steep, densely packed rooflines keep roof cavities shaded and slow to dry, so a whirlybird here is mainly about clearing that trapped moisture rather than cutting summer heat.

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 Glenferrie South
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
Glenferrie South whirlybird installation — your questions
Yes, carefully. We lift the slate course around the fitting point, cut a clean penetration and bed the flashing watertight, so the turbine seats properly without cracking the surrounding slate.
In Glenferrie South, moisture is usually the bigger issue. The heavy canopy keeps roof cavities shaded and slow to dry, so a whirlybird's main benefit here is continuously clearing that trapped moist air.
Often fewer than a larger project home, given the smaller roof footprint, but it depends on the roof's pitch and layout. We assess each roof rather than quoting a standard number for every home.
