How Important is Roof Ventilation?

Having a sturdy roof on your home is important, as it’s the first line of protection against inclement weather. Perhaps equally important is ensuring that your home’s roof is properly ventilated. Unfortunately, many older roofs aren’t equipped with enough ventilation to allow heat to escape, causing attic temperatures to skyrocket. This can be bad news for homeowners for several reasons.

The Dangers of Poor Roof Ventilation

There are two main reasons why a well-ventilated roof is important:

Roof Longevity

When things heat up outside, the temperature on your roof can be close to double the outside temperature. This can cause your attic to heat up significantly, which can lead to premature deterioration. This happens when your roof shingles and underlayment are constantly affected by extreme heat from the attic. Poor ventilation can also lead to a buildup of moisture in your attic, which can cause premature rot in your decking and support trusses as well as mold and mildew growth.

Energy Efficiency

If your monthly energy costs seem to be getting out of hand, poor attic ventilation might be one of the problems. When your attic heats up, it’s natural for the rest of your home to also get warmer. This makes your HVAC system work harder to keep the indoor temperature comfortable. And if your HVAC is in your attic, it doesn’t help that it must perform day in and day out in extreme temperatures.

What Are the Solutions?

Different ventilation options can help lower your attic temperatures and prevent the issues mentioned above. Your roof likely has soffit vents that allow a small amount of ventilation, but it may also benefit from:

  • Ridge vents – Installed along the roof’s peaks, these vents allow hot air to escape from the highest points in the attic.
  • Solar attic fans – These are installed in strategic spots along the roof and pull warm air out of the attic so it can be replaced by cooler air.
