Ice damming can often make the roofing materials weak and ineffective. Roof vents enhance the overall comfort of the house by providing escape hatches for hot stale moist air which can reach temperatures of 150 degrees in summer. The key is to balance incoming air with outgoing and perform an annual maintenance checkup. Recommended airflows of either 10 000mm per linear metre or 25 000mm are determined by the pitch or the design of the roof and can be easily achieved using recommended product combinations.

The benefits of passive roof vents. Your roof will become much more durable once it is vented. Wickright passive ventilation devices dry out wet buildings stop roof parapet and wall leaks mold growth water damage many beautifully designed masonry buildings commercial multi family mixed use and single family buildings with low slope roofs and parapets have severe water damage mold growth and need immediate repair. Wind driven roof vents will pull more air from the attic but only when the wind is blowing.

Passive roof vents encourage natural air flow and work without the aid of motorized fans. Whilst it is possible to retrofit passive ventilation solutions to existing buildings it is highly recommended to incorporate passive ventilation during the design phase of any new building project. Proper ventilation will prevent this from happening. Flat roof vents have no moving parts to break or squeak but don t vent as much air as wind driven vents.

As a result the whole roof system will be prone to damage. All things being equal wind driven turbine vents also known as a whirlybird roof vent do move more air than flat vents but only when the wind blows. They help keep the home more comfortable by providing areas where the heated moist and stale air can exit your home.
