Whirlybird Installation in Ballajura, Perth
Dave works right across Ballajura and the wider City of Swan. The suburb sits about 13km north of the Perth CBD — close enough that travel is always included in the quoted price, same as everywhere else in the metro.
Ballajura sits about 13km from the coast, so the sea breeze arrives later in the afternoon and with noticeably less punch than it has closer to the water. Turbines still contribute, but there is a hot, still window through the middle of the day where they do very little.
Drive around Ballajura and you are mostly looking at 1990s brick and tile, much of it double storey. 1990s builds brought bigger homes and more two-storey construction. On a double-storey house the ventilation problem concentrates upstairs, because those rooms sit directly under the roof with nothing above them to buffer the heat.
Roof pitches from this period are often steeper, and rooflines more complex — multiple hips, valleys and changes of direction. Unit placement matters more here: spread across the roof and high on each section, not clustered on one face.
Most homes in Ballajura need 4 whirlybirds, which comes to $1,250 supplied and installed. Two-storey homes trap the worst of it upstairs, and the rooflines are rarely one simple plane.

Inland — late afternoon breeze
Whirlybirds or Solar Vents in Ballajura?
Ballajura is the part of Perth where this question actually has two defensible answers. The breeze gets here, but late — so a turbine does real work from mid-afternoon and very little before it, which is unfortunately when the roof does most of its heating.
Solar changes the timing rather than just the volume. Sun on the panel means the fan is running from mid-morning, so the heat gets pulled out as it builds instead of after it has already soaked into your ceiling. At $750 it costs more up front than a turbine, and on most Ballajura roofs it does noticeably more.
For a smaller home with decent eave venting, three turbines at $950 is still a perfectly reasonable answer. Dave will give you the cheaper recommendation when it is the right one.

FAQ
Whirlybird Installation Ballajura — 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 Ballajura 6066 is included and there is no call-out fee.
Four units is common, and complex rooflines sometimes need units on more than one roof section. 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.
This is the honest weak point for wind-driven units in Ballajura. The sea breeze arrives late here, so there is a hot, still window through the middle of the day where a turbine does very little. If that bothers you, a solar vent from $750 runs regardless of wind.
Yes — replacements start from $350 per unit. That covers removing the old roof vent, fitting new flashing, installing the new unit and taking the old one away. Most swaps reuse the existing roof penetration, so they take about 30–45 minutes each.
Same-week bookings are usually available in Ballajura. Send an enquiry through the form and Dave will confirm the next slot along with a fixed price.
