Best way to lower attic temperature in summer.

When reroofing use white or pale gray shingles instead of dark ones. They have thermostats that turn the fan on at a recommended preset temperature of 100 110 degrees. The thermostat will usually start at 95 degrees fahrenheit which is the temperature that the attic fan usually starts at. Use a thermostatically controlled roof mounted ventilator.

Install electric ventilators and attic fans which remove hot air from an attic. It will help to keep the attic much cooler in the summertime. As a general rule the lower the outdoor temperature the lower the recommended humidity setting. You want to avoid ice buildup or condensation that could lead to structural problems in your attic.

A ridge and soffit ventilation system an extra 200 during reroofing will reduce attic temperature to around 100 degrees. If you re designing and building a new home keeping an unconditioned attic cooler in summer is pretty much irrelevant. Here are ten different ways to reduce your attic heat temperature and save you money. You could achieve lower attic temps by putting radiant barrier on the rafters but unless you have uninsulated air handlers and ducts up there it wouldn t be economic in a denver climate increasing the heating season energy use more than is offset in cooling costs.

Gable vents around 25 each plus 75 per vent for labor can lower attic temperatures about 10 degrees. Dropping the temperature from 120 150 degrees to roughly the same as the outside temperature will save you enough on your power bill to offset the purchase and installation charge. Just make sure the ceiling is airtight and fully insulated and the temperature in the attic doesn t matter much. Installing attic vents if you don t already have them is another way to assist in the movement of hot and cold air out of your attic.
