Whirlybird Installation for Midvale Homes

Whirlybird installation in Midvale 6056, about 17km north-east of the Perth CBD. Dave's Whirly Birds is owner-operated: Dave quotes the job, Dave does the job, and the price you are quoted is the price you pay.

26km inland puts Midvale at the far edge of the sea breeze's reach. Hot, still afternoons are the norm through summer here, and that is precisely the condition wind-driven whirlybirds handle worst.

Midvale is largely post-war brick and tile. Post-war brick-and-tile homes typically run a low-to-medium pitch with a modest eave overhang. Roof cavities are shallow, which means they heat up fast and transfer that heat down to the ceiling quickly.

Insulation in these houses is frequently original, thin, or has settled and gone patchy over decades. Ventilation will not fix poor insulation, but it does stop the cavity above it acting as a heat store all evening — which is usually the complaint that prompts the call.

Most homes in Midvale need 3 whirlybirds, which comes to $950 supplied and installed. The shallow cavity on a post-war roof heats right through in an afternoon.

Far inland — light, late breeze

Whirlybirds or Solar Vents in Midvale?

Solar, in most cases. Midvale sits far enough inland that wind is the least reliable thing you could power a roof vent with, and hot still afternoons are the norm rather than the exception through summer.

A solar unit sidesteps the problem entirely — it runs on the thing Midvale has in abundance. From $750 installed, no wiring, no electrician, and no running cost, and it is working hardest at the hottest point of the day.

If the budget only stretches to turbines, they are still better than an unventilated roof — but you should go in knowing they will be doing less here than the same units would in Scarborough. Dave would rather tell you that upfront than have you disappointed in February.

How many units for a Midvale home? Two to three units suits most homes of this size and vintage.

"Dave was punctual, professional and had our four whirlybirds installed within two hours. The upstairs bedrooms are noticeably cooler through the afternoon — wish we'd done it years ago."

FAQ

Whirlybird Installation Midvale — Common 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 Midvale 6056 is included and there is no call-out fee.

Two to three units suits most homes of this size and vintage. 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 Midvale. 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.
