Do Whirlybirds Work?
Yes, whirlybirds do work to allow the hot air and moisture trapped within your roof cavity to escape naturally. Whirlybirds also provide a high level of air quality for your home by preventing the build up of any fumes, stale air or damaging condensation. Whirlybirds are essentially designed to cover and protect a hole in your roof. Hot air and moisture can rise up and escape through a whirlybird – whilst the whirlybird turbine and flashings prevents any rain water from entering the roof.
