Proper attic ventilation is an important component of a roof system since it keeps your house warm in winter and cooler in summer. It also extends the life of your roof by venting moisture from your attic to prevent rot, mold, and mildew.
To provide proper attic ventilation, your home should have soffit vents, ridge vents and supplemental roof vents. Soffit vents and supplemental vents including gable, domed or turbine vents bring outside air into your attic while ridge vents exhaust hot air out of your attic.Shingle warranties may make coverage conditional on meeting their minimum ventilation requirements. Consult the manufacturer for specific ventilation requirements when selecting a shingle product.

Allows fresh air to enter the attic, pushing hot and moist air to exit the attic through the roof vent.
