Whirlybird Installation
in Strathmore.
Strathmore's period homes were built long before roof ventilation was standard, leaving original roof cavities with no way for summer heat and moisture to escape, an issue that matters more on homes with original terracotta tile where trapped moisture can affect timber battens and rafters over time.

Why Strathmore roof cavities overheat
Strathmore's period homes were built long before roof ventilation was standard, leaving original roof cavities with no way for summer heat and moisture to escape, an issue that matters more on homes with original terracotta tile where trapped moisture can affect timber battens and rafters over time. A whirlybird uses wind and rising heat to continuously draw that air out, cutting ceiling heat load in the house below and reducing moisture build-up. It's a straightforward retrofit on both original terracotta and later concrete tile roofs across the suburb.
Strathmore's period homes with original terracotta tile often have no built-in ventilation at all, making a whirlybird a bigger practical upgrade here than on a newer, already-ventilated roof.

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 Strathmore
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
Strathmore 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 — whirlybirds are fitted to suit terracotta as readily as concrete tile, with the flashing and fitting adjusted to match your existing roof material.
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.
