Ventilation Profile
Delahey Roofing & Weather Profile
What We See in Delahey
Homes without adequate roof ventilation show condensation on the underside of the roof sarking in winter — moisture from the living space migrates into the ceiling cavity and condenses on the cold sarking surface, promoting mould growth and wetting the insulation.
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
Where a warranty claim or performance question arises, we return and test the extraction performance with a smoke pencil introduced at the soffit inlet — it gives a clear visual indication of whether the cavity is pulling air through the system as designed.
