What is The Purpose of Roof Vents?

You’ve probably heard that ventilation for your home is very important, but what exactly is it? Ventilation is simply the process of providing a continuous supply of outdoor air to the attic space of a home or building and prevent moisture buildup.  Without the right roofing and attic ventilation system, your home may become uncomfortable and cost more to heat or cool. Roofing and attic ventilation systems can protect homes from the expensive roof and structural damage caused by trapped heat, ice dams, moisture and mold. 

Roofing and attic ventilation systems are designed to work around the clock to balance the intake and outflow of cool air and warm air into your home. No matter the month, hot air will accumulate in the attic at the peak of the roof. 

• In summer and warmer months, outside temperatures intensify the effects of this heated air. Without proper venting, this can lead to overloaded air conditioners, poor indoor air quality and can eventually cause shingles to fail, resulting in roof leaks. 

• In winter and cooler months, heated air mixes with water vapor from everyday activities such as bathing. This warm, moist air can linger in the attic, causing mold, mildew, damage to roofing studs and even ice dams when outside temperatures drop.

What is the difference between normal ventilation and poor ventilation?

Proper ventilation consists of 50% intake ventilation placed near the lower part of the attic space, and 50% exhaust ventilation placed near or at the peak of the roof. The exhaust ventilation should be at least three feet higher than the intake ventilation.

What happens when you have poor ventilation?

Well, it can cause a 50-year roof to last only about 10 years. Bad ventilation doesn’t immediately ruin a roof, but enough of it shortens the lifespan significantly. It is estimated that nearly 90% of US homes have some form of improper venting.
