ABOUT ROOF VENTS
Roof vents are used to provide attic ventilation in both summer and winter. In summer, roof vents help to keep attics cool. This avoids the build up of moist summer air which can damage both roof structure and shingles. It also reduces cooling costs by reducing the temperature of the attic. In winter, roof vents help to keep attics dry. This reduces the risk of water backing up under shingles, which can cause damage to the shingles, insulation, and the roof structure.
The most common type of roof vent is the ridge roof vent. This runs along the ridge of the roof, allowing warm rising air to escape. Power roof vents may be fixed into the roof, or into the vertical end gable wall. They may be powered from mains electricity or from solar panels integrated in the roof vent. Static roof vents take the form of roof louvers, wall louvers, or non-electric wind turbines. These use the wind to draw air out of the building using the Venturi effect.

LEADING USA ROOF VENT MANUFACTURERS
Active Ventilation Products: Roof Vents. Active Ventilation Products is based in Newburgh, New York. Since 2006 it has operated from a 63,000 sq ft building which allows for high volume production. It manufactures exhaust and intake ventilators, powered by wind or solar energy, under the Aura brand name. Aura roof vents are designed to produce a continuous exhaust to prevent condensation and the build up of heat in attic spaces. They are active ventilators, operating like a turbine, but without moving parts. Separate sets of slotted vanes create a circular movement of air within the roof vent. The Venturi effect creates a vacuum, which draws air out of the building.
