How important is Roof Ventilation?
Having Roof Vents / Whirlybirds installed in your house is necessary in order for your roof to function properly. The two main functions of the Roof Vent is:
1. Summer
To clear out the hot in your roof space caused by direct sunlight. Hot air rises, so your roof vent is placed at the highest point possible on the roof line. Outside air is drawn in while the hot air inside is expelled, leaving your roof space cooler.
FACT- Your roof space can actually get up 60 degrees in temperature, causing insulation to become less effective and air conditioners to work much harder.
2. Winter
To draw the moisture out of your ceiling area caused by the running of bathroom and stove exhaust fans. The condensation is simply drawn up through the roof vent shaft and expelled through the top.
FACT-your roof space can actually accumulate over ten litres of water through condensation, creating stains on interior walls and ceilings.
Other important benefits of having roof vents installed on your roofs are that they operate absolutely free, saving you on electricity bills. By lowering the power consumed by air conditioners, you are also contributing to the ongoing task of trying to limit green house emissions which is a great thing for the environment.
Using only slight wind for propulsion, roof vents will operate silently 365 days a year!
