Why Bangholme roof cavities overheat
Bangholme's roofs sit in full, largely unshaded sun for most of the day, and on properties with sheds and larger roof spans that heat builds up fast in the cavity above the ceiling. Without ventilation, that trapped heat pushes back down into the living areas and keeps the roof space hot well after the sun goes down. A whirlybird uses wind and the natural rise of hot air to continuously pull that heat out, easing the load on the roof space and any ceiling below it. We fit the turbine into the tile or colorbond roofline with properly sealed flashing, and size the number of turbines to the actual roof area rather than using a single standard fitting.
With little tree shade and long sun exposure across Bangholme's open blocks, roof cavities here run hotter for longer than in leafier suburbs, which makes ongoing heat extraction more valuable than on a shaded suburban roof.

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 Bangholme
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
Bangholme whirlybird installation — your questions
Yes — with little shade, Bangholme's roof cavities absorb more heat over a longer part of the day, so continuous ventilation makes a bigger difference here than on a shaded suburban roof.
Not when the flashing is done properly. We seal the turbine into the tile or colorbond roofline correctly, which is the part that has to be right for the vent to stay watertight.
It depends on the roof area, not a fixed number. We assess the actual size and pitch of the roof and recommend a turbine count that will properly clear the trapped heat.
