DCI Products Inc., Clifton Heights, Pa., offers SmartRidge, a multi-use one-sided ridge vent. It is a shingle-over ridge vent designed for installation along the roof edge, resulting in clean rooflines. Using the company’s SmartVent system, cooler air enters the attic at the soffit level and is drawn up and out of the ridge vent. The single-side venting creates “negative air pressure,” causing hot attic air to be literally pulled out of the house.
