Document wind direction and affected elevations
Wind-driven weather can affect one side of a building more than another and can push precipitation toward laps, edges, ridges, or wall connections. After an event, record the date, likely wind direction if known, first interior symptom, and the elevation where visible material changed. Ground-level photographs of displaced pieces, debris, bent metal, or gutter movement are useful; rooftop access is not. The inspection should compare windward and sheltered areas, examine attachments and transitions, and avoid extending a localized observation to the entire roof without evidence. Temporary protection, diagnosis, and permanent repair need separate descriptions.
- Label photographs by building elevation and record when water or movement first appeared.
- Inspect edges, ridges, laps, penetrations, flashing, and attachments in the affected direction.
- Base the scope on documented locations rather than a whole-roof assumption.
