Cooling Subiaco Roofs — What Actually Works
Whirlybird installation in Subiaco 6008, about 3km west of the Perth CBD. Dave's Whirly Birds is owner-operated: Dave quotes the job, Dave does the job, and the price you are quoted is the price you pay.
Subiaco is far enough inland — about 7km — 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.
Most of what Dave works on in Subiaco is character homes with steep tiled roofs. Older homes here were built before insulation was standard and often before sarking, so the roof cavity behaves differently to a modern one — it heats fast but also sheds heat readily once you give it somewhere to go.
What holds them back is almost always the eaves. Narrow originals, or later work that boxed them in, leaves the cavity with no reliable way to draw replacement air. Adding eave vents alongside the roof units is usually money better spent than a fourth turbine.
Inland — late afternoon breeze
Whirlybirds or Solar Vents in Subiaco?
Subiaco 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 Subiaco 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.

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 Subiaco 6008 is included and there is no call-out fee.
Steep pitch means more cavity volume per square metre of ceiling, so these homes often want one more unit than the floor area alone suggests. 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 Subiaco. Send an enquiry through the form and Dave will confirm the next slot along with a fixed price.
Yes. Subiaco is roughly 3km west of the CBD, comfortably inside the area Dave covers, and travel is included in the quoted price — a quote in Subiaco 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.
