Ventilation Profile
Cairnlea Roofing & Weather Profile
What We See in Cairnlea
On concrete tile roofs from the 1980s and 1990s, the roof space insulation is typically fibreglass batts in place for 30-plus years. Prolonged heat cycling degrades their performance rating — addressing the roof heat load is the most efficient way to get more from the existing insulation.
Why It Happens
Sound attenuation from rainfall on a metal or tile roof is partly achieved by the air gap in the roof cavity. A ventilated cavity allows vibration energy to dissipate rather than transmit directly into the ceiling lining. Adequate ventilation has a marginal but real acoustic benefit in rain noise reduction.
How We Fix It
On Colorbond roofs, turbine penetrations are done with a purpose-formed Colorbond-matched collar flashing that follows the profile of the sheet. Penetrating a Colorbond roof incorrectly causes water ingress at the screw perimeter and profile mismatch — both of which we avoid.
