Cobra Exhaust Vent 10.5 in. x 20 ft. Mesh Roll Ridge Vent Plastic - (Nail Gun Version)

The minimum roof pitch required for the Cobra Exhaust Vent 10.5 in. x 20 ft. Mesh Roll Ridge Vent (Nail Gun Version) is 2:12, with a maximum of 20:12 This slope range is broader than some other ridge vent products in the GAF lineup, making the Cobra Exhaust Vent one of the more versatile options for lower-pitched roofs.

The Cobra Exhaust Vent 10.5 in. x 20 ft. Mesh Roll Ridge Vent (Nail Gun Version) is designed for efficient attic ventilation and is compatible with shingle-over installations. However, its suitability for use underneath concrete roofing tiles depends on specific material compatibility and installation requirements. Key Points: Material Compatibility: Ridge vents must be able to withstand the weight and thermal expansion of concrete tiles. Ensure the vent material is durable enough for heavy roofing materials like concrete tiles. Installation Requirements: Proper venting is critical to allow for downward drying of the concrete deck. A vapor retarder may be necessary to prevent moisture issues. Manufacturer guidelines should be followed to secure the vent without damaging the tiles. Recommendations: Use ridge vents specifically designed for heavy roofing materials like concrete tiles. Consult GAF's technical documentation or contact their support team for confirmation on compatibility with concrete tiles. For further details, you can refer to the Cobra Exhaust Vent product page or GAF's technical documentation. If you need additional assistance, feel free to ask! Please give our technical team a call at 1-800-ROOF-411. They'd be glad to speak with you regarding this particular type of installation.

It can be trimmed down as needed, but please ensure the built-in end cap faces out at the end of the installation so that weather cannot infiltrate. For more, please call us at 877-GAF-ROOF

Hello, this product is NOT intended for use as a ridge cap shingle on shingle, metal or any other roof system type. It is a ridge vent intended for ventilating attic spaces and is covered by an asphalt shingle ridge cap. We highly recommend you reaching out to the metal roofing supplier for their recommendations for compatible ridge caps and/or ridge vents as it relates to their metal roof system. Please give us a call at 877-GAF-ROOF to discuss further. Thank you

Hello, the maximum air slot (centered over the peak) is 3-1/2". For more info, please contact GAF at 877-GAF-ROOF.
