Roof ventilation is the process of allowing air to move through the roof space. As the sun heats the roof, warm air builds up inside the roof cavity. Without a proper escape route, that heat can push down into the rooms below, making the home feel stuffy and uncomfortable.
A roof vent gives that hot air a way out. Depending on the system, this can be done through passive vents, turbine vents, whirlybird vents, ridge vents, or solar-assisted roof ventilation.
The green benefit is simple: roof vents use natural airflow and heat movement to ventilate the home. Hot air naturally rises, and a roof vent allows it to escape instead of being trapped inside the ceiling space. Call IR Installers today at 021 556 4328 for a quote.
