Whirlybird Installation · Ringwood North
Ringwood North's predominantly 1960s-to-80s brick veneer homes were mostly built before roof ventilation was standard, leaving roof cavities with nowhere for summer heat to escape, even under the suburb's heavy tree canopy on its larger, established blocks. A whirlybird uses wind and rising heat to continuously draw that hot air out, cutting ceiling heat load in the house below and, importantly, helping clear the significant extra moisture that Ringwood North's higher rainfall holds against roof timbers. It's a straightforward retrofit suited to concrete tile and Colorbond alike.
Ringwood North's higher rainfall than most of Melbourne's east, combined with heavy tree cover, means better ventilation does double duty here, reducing both summer heat and the dampness that builds up under dense canopy.
Local roof weather
Ringwood North sees around ~5 days above 35°C a year, and on those days an unventilated roof cavity turns into a heat store right above your ceilings.

The process
We look at roof size, pitch and existing airflow to work out how many vents you actually need — no over-selling.
Vents go high on the roof where the hottest air collects, balanced with the eave intake so air can actually move through.
On a tiled roof we lift the tiles, cut a neat penetration, and bed the flashing so it is fully weatherproof.
The turbine is seated in the flashing collar and the tiles are reinstated over the apron, leaving a clean, leak-free finish.
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.
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.
