Why Spotswood roof cavities overheat
Spotswood's Victorian, Edwardian and interwar cottages near Scienceworks were mostly built well before roof ventilation was standard, leaving roof cavities under low, tight rooflines with nowhere for summer heat to escape. A whirlybird uses wind and rising heat to continuously draw that hot air out, cutting ceiling heat load in the house below and reducing moisture that can otherwise sit against roof timbers. It's a straightforward retrofit that sits low on the roofline, suited to terracotta, concrete tile and Colorbond alike, without disrupting the heritage streetscape.
Spotswood's compact heritage cottages often have particularly low, tight roof cavities, and a whirlybird gives that trapped hot air a genuine exit point it wouldn't otherwise have.

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 Spotswood
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
Spotswood whirlybird installation — your questions
Yes — cottages built before ventilation was standard often have particularly low, tight roof cavities with no way for hot air to escape, and a whirlybird gives it a continuous exit point using wind and rising heat.
Whirlybirds sit low on the roofline and are available in colours to match your roof, so they blend in without disrupting Spotswood's heritage streetscape.
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.
