2025 California WUI Code roof-profile closure details

The 2025 California Wildland-Urban Interface Code calls for bird stops at fitting eaves and mudded hip and ridge caps where a roof profile creates an airspace over a combustible deck.

A closure component addresses only the edge or cap detail. The roof deck, underlayment, covering, ventilation, and installation remain separate checks.
