We look at roof size, pitch and existing airflow to work out how many vents you actually need — no over-selling.

Why Yea roof cavities overheat
Yea's inland farming-country summers push real heat into roof cavities with little ventilation, and the town's older established homes in particular were built without much airflow provision. Whirlybirds vent that trapped heat before it radiates down into the rooms below. On tile roofs we lift the tile course, cut a clean penetration, bed the flashing watertight and seat the turbine; on the Colorbond homes and sheds common on Yea's farming properties, the vent is flashed directly into the sheeting. Correctly sized for the roof, a few turbines make a real difference on Yea's hot inland days.
Yea's inland farming-country summer heat, further from Melbourne's coastal moderation than most of our service area, makes cavity ventilation genuinely worthwhile on both older homes and farm buildings.

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 Yea
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
Yea whirlybird installation — your questions
Yes. On Yea's Colorbond sheds the vent is flashed directly into the sheeting rather than under tiles — worthwhile if the shed is enclosed and used regularly, not just for the main house.
Usually two to four, depending on roof size and pitch. Many of Yea's older township homes had no ventilation provision at all, so even a modest number makes a real difference.
Not when flashed correctly, which is where cheap installs fail. We take the same careful approach on Yea roofs as anywhere else we work.
