Your roof is a complex system that requires all part to work cooperatively, and a central component of this system are roofing vents. Today’s wood-framed design and construction techniques of steep-sloped asphalt shingle roofs with an enclosed attic or rafter spaces uses specific design criteria to reduce the likelihood of moisture problems.

Ventilation is a system of intake and exhaust that creates a flow of air. Effective attic ventilation provides year-round benefits for all types of roofing systems, creating cooler attics in the summer and drier attics in the winter, protecting against damage to materials and structure, aiding in reducing energy consumption, and helping to prevent ice dams.

Poor ventilation creates two distinct problems seasonally. In summer, an overheated attic, combined with moisture, can cause a number of problems, including damage to roof decking and roofing shingles that can distort and deteriorate prematurely. Heat that’s absorbed in the attic can also radiate into the living space causing air conditioners, fans, refrigerators, and other appliances to work harder – increasing your energy bills.

In the winter, moist, warm air from the lower portions of your home will rise through the ceiling into the attic, especially through bypasses where electrical and plumbing fixtures are installed. In a cold attic, this warm, moist air condenses on the cold surfaces of the rafters, the nails and other metal, and the attic side of the deck. This moisture can cause the deck to swell, resulting in waviness and buckling of both the deck and the shingles; rot the roof deck, destroying its ability to carry loads and its nail-holding capability; and can dampen insulation leading to wood rot, mold, and mildew, leading to poor indoor air quality in the rest of the home.

Another winter problem caused by poor ventilation is the formation of ice dams. Ice dams form in cooler climates during winter when heat collects in a poorly ventilated and/or inadequately insulated attic space. This freeze-thaw cycle can result in water pooling that can back up under roof shingles and behind fascia boards, soak roof decking and wall sheathing, damage exterior and interior walls, peel paint and ruin ceilings.
