Where to install:
This 12-inch roof vent is ideal for roofs with a 3/12 to 12/12 roof pitch. For a pitch of 3/12 or greater, install this vent no more than 2 feet from the roof's ridge. Doing this will enable you to install your static vent in all climate zones.
How it Operates:
The Round Back Static Roof Vents will remove radiant heat from the attic in the summer and moisture in the winter, making them the ultimate solution for ventilating residential attics year-round. Ventilation helps to make a home more comfortable and energy efficient.
The vented lid is manufactured from one piece of spun aluminum, which prevents rain and snow from entering the attic. The round design is aerodynamic and can withstand wind pressure exceeding 200 mph. All Round Back roof vents are resistant to corrosion and will remain rust-free for the roof's life.
The inner louvers of the roof vent keep insects and animals from entering the attic. The louvers also allow the air to flow freely to the outside.
This 12-inch roof vent is also great for residential roof applications because of its aesthetically pleasing appearance. Round Back Vents are low profile and can be painted to match the color of asphalt shingle roofs.
