Understanding Roof Ventilation

You have probably seen them everywhere, but have you ever wondered exactly what purpose "whirlybird" roof vents serve? Believe it or not, these roof vents extend your roof's life while also increasing the energy efficiency in your home by removing excessively hot air from your attic space. These particular vents generally work by turning with the wind and creating a vacuum effect that sucks out the hot air. They are often paired with other ventilation methods, such as soffit vents, which help create an upward draft in your attic space, allowing the hot air to escape through the whirlybird.

By having an unventilated roof, you run the risk of damaging your new shingles because the prolonged windows of high heat exposure could lead to premature cracking of the shingles. Cracked shingles will then inevitably lead to water leaks, which could then damage the interior of your home.
