6. Ridge Vents

Ridge Vents and associated ventilation is a system of intake and exhaust that creates a flow or fanning of air. With the application of an American Shingles roof, we achieve this by the use of an ingenious and extremely effective ridge vent.

Low profile looks better

The ridge vent is fixed to various ridges of the building and causes the air within the roof cavity to be moved with the process of either convective currents or the wind externally. Although the vent is low profile and clad with cappings matching the American Shingles roof, we offer an aesthetically pleasing option of providing ventilation without the use of ugly rotating cowls typically used on roofs in Australia.

Removes condensation

An American Shingles roof must be ventilated to maximise the International Warranty* offered by CertainTeed here in Australia. The application of the ridge vent removes the effect of condensation forming on the underside of the roof deck in winter and, moves and rotates the hot air that accumulates and builds up in summer. Heat rises through the body of the building as well as radiating through the roof plane.

Bernoulli Effect?

The beauty of the application of the ridge vent with an American Shingles roof is that it draws air from low level intakes at the eaves and exhausts it at the ridge, the highest point of the roof. This allows a constant flow throughout most areas of the attic cavity removing ‘dead areas’. With the baffled designed of the ridge vent, air is ‘sucked’ out of the roof cavity on breezy days due to the Bernoulli Effect.
