Whirlybirds and Solar Vents in Forrestfield
Dave's Whirly Birds covers Forrestfield 6058 and the surrounding City of Kalamunda area. Forrestfield sits about 16km south-east of the Perth CBD, and every job here is quoted at a fixed price up front and completed by Dave personally.
Distance from the coast is the defining factor in Forrestfield. At roughly 22km, the afternoon change is a weak, late arrival, while the heat load on the roof is higher than anywhere closer to the water.
Housing through Forrestfield is dominated by 1970s brick and tile on generous blocks. Large ground-floor footprints are the defining feature of this era, and ceiling area is what drives unit count — a sprawling four-bedroom home from the seventies frequently needs four units where a compact modern two-storey needs two.
Generous eaves are the compensation. Intake is rarely the constraint on these houses, so the extraction you fit is the extraction you get the benefit of.
Far inland — light, late breeze
Why Forrestfield Roofs Usually Want Solar
Forrestfield 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 Forrestfield 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.

Whirlybirds in Forrestfield — Your Questions
Forrestfield 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 Forrestfield 6058 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.
Yes. Forrestfield is roughly 16km south-east of the CBD, comfortably inside the area Dave covers, and travel is included in the quoted price — a quote in Forrestfield 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.
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 Forrestfield. Nothing gets added afterwards.
