Registered Exterior Wall Observer REWO The REWO credential reflects updated standards for moisture intrusion prevention and cladding system failures documented in 2023–24 building code revisions. Exterior wall inspection now emphasizes thermal bridging assessment and air-barrier continuity? areas where inspectors previously relied on visual checks alone. Updated protocols require hands-on evaluation of transitions at windows, doors, and penetrations using infrared detection methods.
