Ridge Or Power Fan Attic Vents

Should we remove one combining an attic vent fan with a ridge vent is not recommended since it can reverse the natural flow of hot air in the attic.

Ridge or power fan attic vents.

This is different from soffit vents which allow air to travel into the attic. Attic power ventilators are mounted to the roof of the home and are connected electronically to a power source and in most cases the home s thermostat. Cool air enters the attic through soffit vents in the eaves. If all this seems like too much to take in you can always call on the pros for help.

Having both a power vent and ridge vent installed on your roof can short circuit the attic ventilation system. Most homes already have some passive attic venting built in. Ridge vents are a passive system simply allowing hot air to rise up through them rather than pushing it out as a fan does. Today s homeowner serves cookies to analyze traffic and better serve you.

Ridge vents openings that run the entire length of your roof along the ridge are often visible only to a trained eye. Fan rarely necessary vents that run along the roof ridge are an alternative to those that exit through the roof decking or gables and if the ridge is long enough they may be the only roof vents. See the benefits of attic ventilation a new roof is more than just shingles. Like attic fans ridge vents are designed to exhaust air that is already inside the attic.

While a simple vent is sometimes used to allow for the passive flow of air it s also possible to add a powered attic fan commonly called an attic power ventilator. This cap features both a back draft damper and bird screen preventing outside air from entering the home and birds and small pests from entering duct work. When the power vent goes on it can actually pull air from the ridge vent which can cause an imbalance of airflow along the underside of the roof deck. Effective attic ventilation systems reduce damaging heat and moisture in your attic promote energy efficiency by helping to reduce the load on your air conditioner in the summer and also reduce the risk of ice dam formation on your roof.

While a power vent fan combined with a ridge vent can work against the natural flow of air through the attic it will still exhaust more hot air than not having a fan at all it s just not the most efficient way to go about it. Hidden in plain sight and often camoflauged by specialty ridge shingles these. Once inside the air heats up and rises higher ultimately exiting through venting at the roof s gables through ridge vents cut into the roof s apex or other vent holes in the roof.
