Ventilation Profile
Mordialloc Roofing & Weather Profile
What We See in Mordialloc
Ceiling insulation condition is always assessed alongside any ventilation proposal. Where insulation has compressed or degraded significantly, the ventilation upgrade alone won't resolve the comfort issue — the two items are interdependent and need to be addressed together.
Why It Happens
In still-air conditions, whirlybirds provide convective rather than wind-driven ventilation — the temperature differential between the hot roof space and ambient air creates a natural upward draft through the turbine. This passive thermal performance is underestimated in still-weather climates.
How We Fix It
The number of units is confirmed after the roof space access inspection — in some cases the visual assessment suggests three units, but the cavity configuration means two are adequate. We don't pad the scope.
