Local Specialist · Shire of Mundaring
Whirlybird Installation in Glen Forrest, Perth
Dave works right across Glen Forrest and the wider Shire of Mundaring. The suburb sits about 23km east of the Perth CBD — close enough that travel is always included in the quoted price, same as everywhere else in the metro.
Glen Forrest is roughly 33km from the coast, which puts it well outside the reliable sea-breeze belt. Summer afternoons here run hotter and stiller than anywhere on the coastal plain, and a wind-driven turbine can sit motionless through the worst of it.
Drive around Glen Forrest and you are mostly looking at a mix of original and rebuilt housing. Housing stock varies widely across the suburb — original homes, renovations and full rebuilds all in the same streets — so what suits one house may be wrong for the one next door.
Rather than guess, the quote works through your roof specifically: how steep it is, what it is made of, what colour it is, and how much air the eaves can let in.
For a typical Glen Forrest home you're looking at 3 whirlybirds — $950, installed in one visit. The housing changes street to street here, so the final number depends on your roof.
- Travel to Glen Forrest is included, never added on
- The quote you accept is the invoice you get
- The person who quotes your Glen Forrest roof is the one who installs
- Licensed, insured, and tidy at the end of the day
Far inland — light, late breeze
Why Glen Forrest Roofs Usually Want Solar
Glen Forrest is about as far from the coast as Dave works, and it shows up in two ways: summer roof temperatures run higher than on the coastal plain, and the wind is much less dependable. Those are the exact conditions where wind-driven whirlybirds disappoint people.
Solar vents are usually the better buy here. From $750 installed, a solar unit runs whenever there is sun on the panel — which out this way is most of the day, most of the summer — and shifts several times the air a turbine manages.
Whirlybirds still have a place in Glen Forrest as a cheap supplement, or on smaller homes where the ceiling area is modest. What Dave will not do is sell you five turbines for a roof that needs one powered unit.

Unit count depends heavily on which vintage your particular house is. 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 Glen Forrest. Send an enquiry through the form and Dave will confirm the next slot along with a fixed price.
Yes. Glen Forrest is roughly 23km east of the CBD, comfortably inside the area Dave covers, and travel is included in the quoted price — a quote in Glen Forrest 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.
