Whirlybird Installation for Winthrop Homes
Whirlybird installation in Winthrop 6150, about 12km south 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.
With about 8km between Winthrop and the ocean, the afternoon change has lost a good deal of its strength by the time it arrives, and it arrives late. Worth knowing before you decide between wind-driven and powered ventilation.
The roof stock in Winthrop is mainly 1980s brick and tile. 1980s homes tend toward larger floor plans and slightly higher pitches than the decade before, with roof cavities to match. Ceiling areas of 180–250m² are common, which puts most of them in the three-to-four unit range.
Eave venting is usually present but sometimes minimal. Where it is tight, adding eave vents alongside the roof units delivers a better result than simply bolting on more extraction.
For a typical Winthrop home you're looking at 4 whirlybirds — $1,250, installed in one visit. Homes from this era usually run 180 to 250 square metres of ceiling.

Inland — late afternoon breeze
Whirlybirds or Solar Vents in Winthrop?
Winthrop 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 Winthrop 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 Winthrop — 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 Winthrop 6150 is included and there is no call-out fee.
Three to four units covers most homes of this era. 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 — 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 Winthrop. Send an enquiry through the form and Dave will confirm the next slot along with a fixed price.
Yes. Winthrop is roughly 12km south of the CBD, comfortably inside the area Dave covers, and travel is included in the quoted price — a quote in Winthrop 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.
