Why Kilmore roof cavities overheat
Kilmore's regional summers push serious heat into roof cavities that were rarely built with much ventilation, particularly in the older township homes. 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 roofs common on Kilmore's newer estate homes, the vent is flashed directly into the sheeting. Correctly sized for the roof, a few turbines make a real difference on Kilmore's hot regional days.
Kilmore's regional summer heat, without the coastal moderation Melbourne's bay suburbs get, makes cavity ventilation genuinely worthwhile on both the older township homes and the newer estate builds.

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 Kilmore
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
Kilmore whirlybird installation — your questions
Yes. On Kilmore's newer Colorbond homes the vent is flashed directly into the sheeting rather than under tiles — a routine, weatherproof install.
Usually two to four, depending on roof size and pitch. Kilmore's older homes often 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 Kilmore roofs as anywhere else we work.
