Attic ventilation is vital to the health of your home; poor ventilation can lead to dry rot, mold, and other issues. Although gable vents are the most common type of attic ventilation, there are several alternatives that may meet your needs as a homeowner.
These vents, are also called roof line vents, or eyebrow vents, are composed of a sheet metal cylinder and a flashing collar with a hood to keep water out. They are installed in the roof surface itself by a process that involves cutting holes in the roof, nailing the collars to the roof sheathing, and then laying shingling around the vents. The more static vents, the more effective this method of attic ventilation is. The most significant disadvantage to this method of ventilation is the possibility of leaks, which may result in roof damage.
This type of attic ventilation consists of aluminum panels with louvers punched into them to facilitate air flow. Screens are adhered to the vents to keep out insects and debris. Soffit vents are installed by cutting holes in the existing soffit and installing the vents over the holes. The number of vents needed depends on the size of the space being ventilated.
