Powered attic ventilators are the worst way to try to keep your attic cool. That cuts cooling costs and prolongs shingle life.

Properly sealing these leaks can save as much as 10 every month on your power bill. The air pushes up into the attic through the soffit vents and out through the ridge vents providing a continuous flow. Good ventilation allows the heat and moisture to escape. In the summer good attic ventilation reduces heat buildup.

Gable vents around 25 each plus 75 per vent for labor can lower attic temperatures about 10 degrees. Install electric ventilators and attic fans which remove hot air from an attic. A ridge and soffit ventilation system an extra 200 during reroofing will reduce attic temperature to around 100 degrees. These keep the attic cooler than dark shingles.

Ridge and soffit vents are also helpful for venting hot air and keeping an attic cool but you ll need a little extra help as this method alone probably won t remove enough heat to keep the space comfortable enough to live in. When reroofing use white or pale gray shingles instead of dark ones. Ridge vents are the exhaust vents that are located along the ridgeline of your roof.

Without ventilation an attic s summertime temperature can easily.

They ve been well discussed here and other places but briefly they re not cost effective don t deal with the problem where it starts are using convection to solve a radiant heat problem and can even be dangerous by backdrafting combustion appliances and. Many homeowners falsely assume that since their attics are extremely hot in the summer the best way to reduce their cooling load is to get the heat out of the attic.
