Why Highett roof cavities overheat
Highett's post-war brick veneer homes were built with minimal roof ventilation by today's standards, so the roof cavity heats up through summer and holds that heat well into the evening. A whirlybird draws that hot air out continuously using wind and rising heat, no power required. On the concrete and terracotta tile roofs common across the suburb, we flash the turbine in carefully under the tile course so it stays weatherproof despite the salt-laden bayside air that can accelerate wear on poorly sealed fittings. With Highett's open, sun-exposed streets, the summer heat-load benefit is the main driver here.
Highett's bayside exposure means roofs take on more direct sun and salt air than inland suburbs, so a well-flashed, corrosion-resistant whirlybird install matters here more than in a typical suburban street.

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 Highett
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
Highett whirlybird installation — your questions
We fit corrosion-resistant turbines and flash them properly, which matters more in Highett's bayside position than in an inland suburb where salt exposure isn't a factor.
It reduces the heat that builds up in the roof cavity and radiates into the ceiling below, easing the load on your air conditioner. On Highett's sun-exposed roofs that difference is noticeable by late afternoon.
Most standard Highett homes need two to four, depending on roof area and pitch. We assess your roof rather than fitting a generic package.
