Roof Ventilation for Kelmscott Homes
Roof ventilation for Kelmscott 6111, about 26km south-east of the Perth CBD in the City of Armadale. Owner-operated, fully insured, and priced up front before anything is booked.
At around 24km inland, Kelmscott gets the least benefit from the Fremantle Doctor of anywhere Dave works. Roof temperatures run higher and the wind is less dependable — the two conditions that most favour a powered solar vent over a turbine.
Kelmscott is largely 1980s brick and tile. Floor plans grew through the eighties and roof pitches came up slightly with them, so cavity volume per square metre is higher than on a fifties home of the same footprint. Three to four units is the usual landing point.
Where these houses catch people out is eave venting that looks adequate and is not. It is worth an actual look rather than an assumption, because it changes what the extraction can achieve.
Far inland — light, late breeze
Why Kelmscott Roofs Usually Want Solar
Kelmscott 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 Kelmscott 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.

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 Kelmscott 6111 is included and there is no call-out fee.
Three to four units covers most homes of this era. 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 Kelmscott. 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.
