Fit and Compatibility:
Installs as an off-ridge vent on the roof field and pairs with other O'Hagin vents for additional ventilation. Confirm flange height (4 in.) suits your roof covering type before ordering.

Expert Verdict — Reviewed by the SuperArbor Pro Desk
In Wildland Urban Interface zones, specify Fire & Ice style vents wherever code or the local fire official requires ember-resistant attic ventilation; standard vents can admit embers during wildfire events. Verify the 4 in. flange matches the exposure and profile of your roof covering, and keep the vent matrix unobstructed by underlayment during installation. Pair with balanced intake ventilation so the attic still draws air properly.
Check local fire codes and WUI requirements before installation, and use roof-work fall protection when cutting and setting the vent.
