Mount Lawley Whirlybird Installation and Replacement
Mount Lawley 6050 sits about 4km north-east of the Perth CBD, in the City of Stirling. Dave installs and replaces whirlybirds and solar roof vents throughout the suburb — fixed prices, no subcontractors, travel included.
With about 10km between Mount Lawley 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.
Drive around Mount Lawley and you are mostly looking at character homes with steep tiled roofs. Character housing brings a big, steeply pitched roof cavity — which holds a lot of hot air, and stratifies it hard up under the ridge. That is good news for ventilation: there is plenty to extract, and units placed high do real work.
The catch on older homes is intake. Original eaves were often narrow, and a lot have since been lined or boxed in during renovations, which quietly seals off the airflow path. Extraction without intake achieves very little, so this is the first thing to check.
Inland — late afternoon breeze
Whirlybirds or Solar Vents in Mount Lawley?
Mount Lawley 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 Mount Lawley 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.

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 Mount Lawley 6050 is included and there is no call-out fee.
Steep pitch means more cavity volume per square metre of ceiling, so these homes often want one more unit than the floor area alone suggests. 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.
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 Mount Lawley. 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.
Not necessarily, though most people are. Dave will talk through placement before starting, and the job typically takes one to two hours. Access to the roof is all that is strictly needed.
