Ventilation Profile
Thornhill Park Roofing & Weather Profile
What We See in Thornhill Park
Older homes with slate or terracotta roofs and no ceiling insulation were built in an era when ventilation was provided by the thermal mass of the roof covering and the permeability of the building envelope. Modern sealed construction requires deliberate mechanical ventilation to compensate for the reduction in natural air exchange.
Why It Happens
Condensation in roof spaces occurs when moisture-laden air from the living area enters the ceiling cavity and contacts a surface below its dew point. The dew point in Melbourne winters is regularly above the temperature of uninsulated roof sarking. Ventilation dilutes moisture concentration and reduces condensation frequency.
How We Fix It
Placement is determined by cavity mapping — we access the roof space before finalising positions to confirm there are no obstructions between the proposed turbine location and the soffit inlet. Trusses, downlights, and HVAC ductwork can all redirect airflow in ways not visible from the roof surface.
