Whirlybird Installation in Girrawheen, Perth
Dave works right across Girrawheen and the wider City of Wanneroo. The suburb sits about 12km north of the Perth CBD — close enough that travel is always included in the quoted price, same as everywhere else in the metro.
Girrawheen sits about 8km back from the coast. The sea breeze does reach here — it just reaches here after the worst of the day's heat has already built up in your roof, which is the crux of the whirlybird-versus-solar decision locally.
Drive around Girrawheen and you are mostly looking at 1970s brick and tile on generous blocks. Seventies homes are the bread and butter of this trade: broad single-storey footprints, tile roofs at a workable pitch, and enough ceiling area that two units almost never cuts it.
They also tend to be the easiest to get right, because the eaves are wide and properly vented. When intake is not the limiting factor, adding extraction produces the result you actually expect.
The usual answer in Girrawheen is 4 whirlybirds, $1,250 all up. Those big single-storey footprints put a lot of ceiling under one continuous roof.

Inland — late afternoon breeze
The Honest Recommendation for Girrawheen
Being straight about it: wind-driven whirlybirds under-deliver in Girrawheen compared with what they do on the coast. Not uselessly — but the still window through the middle of a hot day is real, and it is the window that matters most.
Where the budget allows, a solar vent is the better tool here. It runs off the sun rather than the wind, which out this way is the far more dependable of the two, and a single unit at $750 often replaces three or four turbines.
Mixing the two is common and works well: one solar vent as the workhorse, a couple of turbines to keep pulling once the afternoon breeze finally shows up. Dave quotes whichever combination actually suits the roof.

FAQ
Whirlybird Installation Girrawheen — 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 Girrawheen 6064 is included and there is no call-out fee.
Large single-storey footprints mean three to four units is typical rather than two. 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 Girrawheen. Send an enquiry through the form and Dave will confirm the next slot along with a fixed price.
Yes. Girrawheen is roughly 12km north of the CBD, comfortably inside the area Dave covers, and travel is included in the quoted price — a quote in Girrawheen 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.
