Roof Ventilation & Whirlybird Installation
Why Roof Ventilation Matters in Auckland
Auckland's humid climate means a lot of moisture ends up in the roof space, from cooking, showers, drying clothes and simply breathing. Without a way out, that moist air condenses on the underside of the roof, especially on cold nights under long run iron. The result can be dripping, damp insulation, mould and rust from the inside.
Good roof ventilation lets that moist air escape and helps keep the roof space cooler in summer. It is one of the simplest ways to make a home drier and healthier.
Signs of Poor Roof Ventilation
Look for mould spots on the ceiling, a musty smell, damp or compressed insulation, condensation dripping from the underside of the iron, and a roof space that feels very hot in summer.
Whirlybirds and Other Ventilation Options
Whirlybirds are wind-driven turbine vents that draw air out of the roof space without power. We can also install ridge vents, eave vents and other passive options to suit your roof. The right approach depends on the size and shape of the roof space, the roofing material and where fresh air can come in.
We flash every vent into the roof properly so you get the ventilation benefit without creating a new leak point.
