Westlake Royal Zephyr Roll 13.4 in x 33 ft Universal Ridge Vent & Weather Block
This is a Westlake Royal Zephyr Roll universal ridge vent and weather block in a 13.4 in wide by 33 ft long roll for tile roofing. It vents the ridge while blocking weather and debris, and installs under tile ridge caps. One piece is one roll.
Key Features:
- Wider vent roll: The 13.4 in width suits wider ridge caps and tile profiles than narrower vent rolls.
- Universal design: Zephyr Roll serves as both a ridge vent and a weather block in tile roof assemblies.
- Full ridge coverage: Each roll is 33 ft long, allowing long continuous ridge runs with fewer joints.
- Listed standards: Applicable standards include ES ESR-2015, CRRC Approved and Energy Star Approved.
- Manageable weight: Each roll weighs approximately 7.6 lb for easy rooftop handling.
- Weather protection: Acts as a weather block against wind-driven rain and debris entering the ridge.

Expert Verdict — Reviewed by the SuperArbor Pro Desk
Confirm the ridge opening width and cap span before choosing between the 11 in and 13.4 in Zephyr Roll sizes; the wider roll suits broader cap coverage. Install over the ridge opening per the ESR-2015 report details, lapping ends cleanly on long ridges. Pair with the same-brand tile system components for a matched assembly.
Ridge work requires fall protection and stable footing; install per the manufacturer's instructions and local code.
