Why Maidstone roof cavities overheat
Maidstone's older weatherboard and brick cottages near the Maribyrnong River often have compact roof cavities with little original ventilation, so heat builds up quickly in summer and lingers into the evening. A whirlybird vents that air out continuously using wind and rising heat, with nothing to wire in and nothing that stops working during a power outage. On the terracotta cottage roofs we flash the turbine carefully under the tile course to keep the install weatherproof and sympathetic to an older roof; on the post-war brick veneer and newer Colorbond streets further out, it's a more straightforward fit.
Maidstone's older roof cavities near the river flats hold both summer heat and winter dampness longer than a newer home would, so venting does real work easing both problems through the year.

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 Maidstone
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
Maidstone whirlybird installation — your questions
Often, yes. Older cottage roof cavities here tend to hold heat and moisture longer than newer builds, so venting makes a clearer difference to comfort and to reducing damp timber risk over time.
Most Maidstone homes need two to four, based on the roof's total area and pitch. We assess your specific roof rather than fitting a generic package.
Not when flashed properly. We bed the flashing under the tile course and seal it thoroughly, which is where rushed installs on older roofs typically go wrong.
