An unventilated attic can reach 150 degrees in the heat of summer. An overheated attic can bake asphalt shingles on the roof and cause them to deteriorate. And, it can cause your air conditioner to work harder than it needs to, sending your energy bills soaring with the temperature. To head off these problems, consider these options for bringing your attic’s temperature down:
- Install electric ventilators or attic fans, which remove hot air from an attic. They have thermostats that turn the fan on at a recommended preset temperature of 100-110 degrees.
- Alternatively, install passive vents such as gable, soffit and ridge vents, which are openings in the roof that allow hot air to escape.
- Install attic insulation with an R-factor of at least 19. This will help keep the hot attic air from heating your living space.
