Continuous attic ventilation allows your attic to breathe. Instead of trapping heat in your attic — potentially causing roof rot from excess moisture — it is ventilating the hot air and keeping humidity levels down.
One way that attics are ventilated is by installing soffit vents on the underside of your home’s eaves. On most homes, there is usually some type of vent at the top point of the roof that allows the fresh air to be drawn in through the soffit vents and the hot air to be released through the rooftop vent. Gable vents can also be used on the exterior wall of the attic to allow the hot air to be released while adding a decorative element to your home.
Allowing the hot air in your attic to be exchanged with outside air helps reduce heating and cooling costs. Because your home is not retaining very high temperatures, your air-conditioning system doesn’t have to try so hard to keep up.
The same thing occurs in the wintertime as heat from your home is retained in the attic. It is best to have a properly insulated attic for this purpose.
When the energy crisis of the 1970s hit, the way homes were built was re-evaluated. Insulation and weather-stripping became household words and in turn, heating and cooling bills started going down. As more and more energy efficient homes are built, continuous attic ventilation is becoming a standard addition.
