Ridge Vent

CertainTeed Ridge Vent is a continuous exhaust vent for the roof ridge. An external wind baffle deflects wind and weather over the vent and creates low pressure above it, which pulls air out of the attic. Cap shingles are mounted over the top of the vent.

The 12 inch filtered version is the configuration described here. It belongs to CertainTeed's residential roof ventilation range.

The vent is molded from polypropylene resin that passes the ASTM G155 advanced weathering test with less than 10% variance. It is furnished in black.

• External wind baffle over the vent.
• Internal weather filter that reduces infiltration of windblown snow, rain and dust.
• Built-in ventilating, weather tight end plug that flexes for different roof pitches and protects the roof decking.
• Weep holes on 4 inch centers for water shedding from the cap shingles.
• At least 10 pre-formed nail bosses for positioning the vent on the roof before cap shingling.
• Integral ribbing that maintains the vent profile on various roof pitches and during cap shingling.
• Louver openings no wider than 1/4 inch, sized to limit insect entry and windblown debris.

Each vent has 18 square inches of net free area per linear foot. It accommodates roof pitches from 3/12 to 16/12. The vent is rated wind driven rain resistant to 110 MPH.

The vent is capable of having cap shingles fastened with a nail gun set to 100 PSI without breakage, and of installation in various climate zones across the US and Canada.

Ridge Vent is a molded, low-profile vent less than 1 inch high. It is made in four versions.

The Class A fire rated version meets UL standards and has an internal weather filter. The unfiltered version uses external baffles. Pre-printed slot guides cover truss and ridge pole construction, and pre-drilled nail holes are provided. Cap shingles can be standard shingles or hip and ridge accessory shingles. Intake ventilation, such as soffit vents or CertainTeed Intake Vent, is paired with it.

Code body approvals listed are the Texas Department of Insurance, UL Classified, Miami Dade Approved and ICC Evaluation Service. The vent carries an approval report with the Texas Department of Insurance and with the Miami-Dade County Building Code Compliance Office.

The product is covered by a Lifetime Limited Warranty and 5-Year SureStart Protection.

Ridge Vent sits along the upper ridge below the cap-shingle course, over a slot in the deck. It is used with asphalt shingle roofing whose ridge cap is nailed through the vent. Filtered and unfiltered formats exist; the figures on this page are for the 12 inch filtered vent.
