Whirlybird Installation in Duncraig, Perth
Dave works right across Duncraig and the wider City of Joondalup. The suburb sits about 17km north of the Perth CBD — close enough that travel is always included in the quoted price, same as everywhere else in the metro.
About 3km separates Duncraig from the ocean. That is close enough for a dependable summer sea breeze, and far enough that salt is a background concern rather than a constant one.
Drive around Duncraig 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.
Near-coastal — reliable sea breeze
What Works Best on a Duncraig Roof
The default recommendation in Duncraig is wind-driven, and it is a genuine recommendation rather than an upsell avoided — the breeze here is reliable enough that turbines are not a compromise.
Dave steers people toward solar in two situations locally: large ceiling areas where the turbine count gets silly, and roofs that are boxed in by surrounding two-storey homes so the wind never really reaches them. Neither is the majority case in Duncraig.
Whatever goes on, the unit quality matters more than most people expect. Salt still reaches this far inland in reduced quantities, and it finds cheap bearings eventually.

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 Duncraig 6023 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, 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 Duncraig. 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.
