Solar Attic Fan
Roof Breathers: A roof without sufficient ventilation can lead to a moldy attic. Roof breathers are an exhaust ventilation system designed for attics. Our technicians will calculate exactly how much ventilation your attic requires and will install new professional-grade vents in your roof.
Eave/Soffit Vents: Many homes have attic inlet ventilation installed on the soffits or eaves. When inlet ventilation is insufficient, mold can start growing in the narrow part of your attic, then slowly spread toward the roof ridge. Our team can assess how much ventilation you need, then install additional proper ventilation to keep your attic clean and dry.
Solar Attic Fans: The best solution for a “boiling” attic is an attic fan. Attic fans create high air circulation in the attic and suck the heat out. A professional attic fan can be roof mounted or gable mounted and can reduce the temperature by over 40 degrees! Attic fans are a great way to reduce your cooling expenses over the summer and prevent overheating and excessive moisture buildup in your attic.
Bathroom/Kitchen Fan Flapper Vents: Every fan located in your attic, such as bathroom or kitchen fans, must be exhausted out of the roof safely. A bathroom fan discharging steam and moisture into your attic is very likely to cause mold growth, where a kitchen fan that’s pumping smoke, steam and odor is dangerous and harmful to your attic. Our technicians will install proper vents in your roof with built-in dampers and connect new ducts from the fan to the roof vent.
Rafter Vents (Baffles): Before installing “blown-in” insulation in attics, it’s crucial to protect the attic inlet ventilation (either eave or soffit vents) with proper baffles. Baffles, or rafter vents, are essentially blocking boards that go between the rafters from the bottom of the vent and extend approximately 4 feet up towards the roof ridge. They ensure clear air passage and prevent blockage that can be caused by the insulation.
Crawl Space Vent Fan: If your crawl space doesn’t have enough passive ventilation or has high moisture levels, a crawl space vent fan can solve your problem. Our fans include adjustable de-humidistats and can make up for insufficient ventilation in your crawl space, preventing mold and musty odors.
