Treeby Whirlybird Installation and Replacement
Treeby 6164 sits about 19km south of the Perth CBD, in the City of Cockburn. Dave installs and replaces whirlybirds and solar roof vents throughout the suburb — fixed prices, no subcontractors, travel included.
Treeby is far enough inland — about 12km — that the sea breeze is a softer, later arrival. Wind-driven units are not useless here, but they are working fewer effective hours than the same units bolted to a roof on the coast.
Treeby is largely newer estate housing, a lot of it Colorbond. Modern estate housing stacks the odds against you: dark roof colours that absorb heat rather than reflect it, wide footprints built close to the boundary, and eaves trimmed back to almost nothing to fit the block.
The result is a very hot cavity with nowhere to draw replacement air from. Extraction on its own hits a ceiling fast here, and sorting the intake is usually the higher-value half of the job.
The usual answer in Treeby is 4 whirlybirds, $1,250 all up. Dark Colorbond over a wide footprint is about the hottest combination going in Perth.

Inland — late afternoon breeze
Why Solar Vents Often Win in Treeby
This is where the advice changes. In Treeby the sea breeze arrives late enough that wind-driven turbines miss the worst of the heat — your roof cavity peaks in the early afternoon, and the Doctor often does not turn up until after that.
A solar vent runs on sunlight instead, so it is at full output precisely when the roof is hottest. One unit at $750 typically moves more air than three turbines at $950, and it does not care whether the wind is blowing.
That said, plenty of Treeby homes do perfectly well on whirlybirds alone — particularly smaller single-storey places with well-vented eaves. A common middle path here is one solar vent doing the heavy lifting plus a couple of turbines contributing whenever the breeze is up. Dave will tell you which of the three makes sense for your roof rather than defaulting to the dearest option.

FAQ
Whirlybird Installation Treeby — Common Questions
From $350 for a single unit supplied and installed. Two units are $650, three are $950, and each unit after that adds $300. Travel to Treeby 6164 is included and there is no call-out fee.
Wide footprints and dark roofs push these homes toward four-plus units, or one to two solar vents. The general rule is one 300mm unit per 50–60m² of ceiling area, adjusted for pitch and how much intake venting the eaves provide. Dave works out the exact number from your details before quoting.
Same-week bookings are usually available in Treeby. Send an enquiry through the form and Dave will confirm the next slot along with a fixed price.
Yes. Treeby is roughly 19km south of the CBD, comfortably inside the area Dave covers, and travel is included in the quoted price — a quote in Treeby costs the same as one anywhere else in the metro.
Not if it is flashed properly. The flashing keeps water out, not the sealant — a unit bedded in silicone will eventually let go. Dave fits new flashing suited to your roof type on every install, which is the difference between a dry ceiling and a callback.
Yes, along with tile. Metal roofs use a purpose-made soaker or flashing fitted under the upper sheet and over the lower one, with matching screws and neoprene washers. On low-pitch Colorbond, placement high on the slope and clear of ridge caps matters more than it does on tile.
