Ridge vent is an important component of a sound roofing system. Ridge vent acts as the exhaust valve for hot air that gets trapped in the attic. The newest technology in the market actually promotes the escape of hot air and looks aesthetically pleasing compared to the metal ridge vents on new construction homes. The ridge vent works in tandem with the air intake areas of a home, most commonly the soffit or overhangs of the roof. A properly vented roof is the key to a long lasting roof with little or no maintenance required.
