Powered completely by solar energy, a solar attic fan improves attic air circulation resulting in a healthy, energy-efficient home.
How do you tell if attic is properly vented?
How to determine whether you need better attic ventilation
- Look at your eaves and roof.
- Touch your ceiling on a warm, sunny day.
- Thick ridges of ice on your eaves in winter are a sign of poor attic ventilation.
- Warm air that escapes living space also carries moisture that will condense on rafters or roof sheathing.
What happens if attic is not vented?
But in homes without appropriate insulation and ventilation in the attic, heat migrates. Meanwhile, because hot air is full of moisture, all that water hanging out in your attic is causing condensation to build up. Excess heat and condensation can cause major damage to your roof and roofing materials.
Do you still need an attic fan when you have a ridge vent?
An attic fan isn’t recommended if you have ridge vents. In this scenario, the attic fan will draw cool, conditioned air out of your house and raise your A/C bill. It could also stop hot air from exiting through the ridge vent and pull in rainwater during a storm, which can eventually make your attic leaky or moldy.
