Why Wattle Glen roof cavities overheat
Wattle Glen's established homes trap summer heat in poorly ventilated roof cavities that radiate down into the rooms below, and near the creek the roofs also collect winter moisture that condenses in the cavity. Whirlybirds vent both. On the concrete-tile roofs common here we lift the tile course, cut a clean penetration, bed the flashing watertight and seat the turbine. In Wattle Glen's shaded, tree-covered setting the winter side of ventilation matters as much as the summer heat — clearing the moist air protects the roof timbers and insulation year-round.
Wattle Glen's creekside tree cover makes winter cavity moisture a genuine issue, so venting the roof here protects the timbers from condensation as much as it eases the 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 Wattle Glen
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
Wattle Glen whirlybird installation — your questions
Yes — in this shaded, creekside suburb, venting the warm, moist air out of the roof in winter stops it condensing in the cavity and feeding mould.
Most homes need two to four turbines set high on the roof. We assess the roof and recommend the right number for its size and pitch.
Not when flashed correctly. On tile roofs we bed and seal the flashing under the tile course for a fully weatherproof finish.
