Whirlybird Installation in Lesmurdie, Perth

Dave works right across Lesmurdie and the wider City of Kalamunda. The suburb sits about 24km east of the Perth CBD — close enough that travel is always included in the quoted price, same as everywhere else in the metro.

Distance from the coast is the defining factor in Lesmurdie. At roughly 29km, 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 Lesmurdie is dominated by 1980s brick and tile. Housing from the eighties sits between the sprawl of the seventies and the height of the nineties — bigger than it looks from the street, with roof cavities generous enough to hold a serious amount of hot air.

Intake venting from this period is inconsistent. Some homes have plenty; others have the bare minimum, and on those the eaves are the first thing to sort out before adding more units up top.

Far inland — light, late breeze

Whirlybirds or Solar Vents in Lesmurdie?

Solar, in most cases. Lesmurdie 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 Lesmurdie 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.
