Whirlybirds and Solar Vents in Coolbellup
Dave's Whirly Birds covers Coolbellup 6163 and the surrounding City of Cockburn area. Coolbellup sits about 15km south of the Perth CBD, and every job here is quoted at a fixed price up front and completed by Dave personally.
The coast is about 5km west of Coolbellup — near enough that the afternoon change still carries real strength by the time it arrives. Turbines do well on these roofs without needing to be oversized.
The roof stock in Coolbellup is mainly post-war brick and tile. Low-pitched roofs from this era hold less air than you would think, and that works against you — a small cavity reaches a high temperature quickly and passes it on to the ceiling below with very little delay.
Eave overhangs from the fifties are modest, so intake is often limited before you even consider whether anything has been boxed in since. Worth checking properly rather than assuming.
Most homes in Coolbellup need 3 whirlybirds, which comes to $950 supplied and installed. The shallow cavity on a post-war roof heats right through in an afternoon.

Near-coastal — reliable sea breeze
Whirlybirds or Solar Vents in Coolbellup?
Wind-driven whirlybirds are the sensible starting point in Coolbellup. The sea breeze is consistent enough through summer that turbines earn their keep, and at $350 a unit they are the cheapest effective way to get heat out of the roof.
Where Dave suggests going solar in Coolbellup is on larger homes — anything over roughly 250m² of ceiling area — where you would otherwise be fitting five or six turbines. At that point one or two solar vents move more air for similar money and keep the roofline cleaner.
Salt is a milder concern this far back from the water than it is right on the coast, but it is not zero. It is still worth specifying a decent unit rather than a bargain one.

FAQ
Whirlybird Installation Coolbellup — 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 Coolbellup 6163 is included and there is no call-out fee.
Two to three units suits most homes of this size and vintage. 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.
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.
The unit, correct flashing for your roof type, cutting and fitting, removal and disposal of any old unit, full clean-up including metal swarf off the roof and out of the gutters, and travel to Coolbellup. Nothing gets added afterwards.
Yes, and it is the benefit people forget. Warm moist air from inside the house rises into the roof cavity and condenses on cold surfaces overnight — that is where damp insulation and mould on the sarking come from. The same airflow that removes summer heat removes winter moisture.
As high as practical and spread across the roof rather than clustered — usually on the western or south-western slope so they catch the afternoon sea breeze. On a complex roofline with separate sections, units may need to go on more than one face to cover the whole cavity.
