One of the most overlooked aspects of roof repair and maintenance projects is roof ventilation. In today’s blog, one of the top roofing companies in NY, Expert Contracting, shares the importance of roof ventilation, and how it works.
How Does Roof Ventilation Work?
Warm and moist air gathers and rises up to your attic, which creates a stacking effect. Having a roof ventilation system should redirect heat and humidity away from the attic, and replace it with fresh, cool air from the air intake vent. There are two kinds of attic ventilation systems:
- Passive Ventilation. Passive ventilation features exhaust vents on the roof ridges which release warm and humid air. This releases pressure in the attic that pulls fresh air through the intake vents at the roof soffits, along the roof edges. Both the ridge and soffit vents need to be sized properly to ensure proper air flow.
- Mechanical Ventilation. Your roof replacement expert would recommend adding a mechanical ventilation system if the attic is too large that passive ventilation won’t cut it. This uses mechanical fans to release air from your attic. The fans can be powered through electricity, or using solar panels.
Benefits of Roof Ventilation
- Reduces HVAC Bills. Heat trapped in your attic can radiate back to your living space, which can make your home feel uncomfortable, requiring you to use your cooling system. With proper ventilation, you’ll have to rely less on your cooling unit since the air is much cooler.
- Prevents Mold and Mildew Growth. Mold spores thrive in damp or moist environments. Keeping your attic dry and cool prevents them from growing, and effectively keeps your roof in good shape for the years to come.
