Why Craigieburn roof cavities overheat
With little tree shade across Craigieburn's open estate blocks, roofs take the full force of summer sun and the cavity heats up quickly. Whirlybirds let that trapped heat escape before it radiates down into the rooms below. On Craigieburn's concrete-tile roofs we lift the tile course at the vent, cut the penetration, bed the flashing watertight, and seat the turbine; on newer Colorbond estate roofs the vent flashes straight into the sheeting — either way, getting the flashing right is what matters most. Out on the northern plains where Craigieburn bakes in summer, a few well-placed turbines take real load off the cooling, and clear winter condensation from the cavity too.
Craigieburn's exposed estate blocks and hot northern location mean roofs bake in summer with no tree cover to help, so venting the cavity does more here than in a shaded inner suburb.

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 Craigieburn
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
Craigieburn whirlybird installation — your questions
Most homes here need two to four, placed high where the hottest air collects. We assess the roof and recommend the right number for its size and pitch rather than overselling.
Yes. On Craigieburn's newer metal roofs the vent is flashed directly into the sheeting rather than under tiles. The method differs but the key is the same — a properly sealed, weatherproof flashing.
Turbines release the roof-cavity heat that radiates into your rooms, easing the cooling load. On Craigieburn's hot, exposed blocks the difference upstairs on a summer afternoon is noticeable.
