Drains and scuppers move water through different building details. Their condition, connections, and intended role need to be understood within the roof's drainage design. Clearing visible debris does not establish that the entire drainage route is functioning.
What to do next
Ask which components were inspected and whether downstream drainage needs another trade's assessment. Record any inaccessible areas. A maintenance report should distinguish a clear inlet from a verified path through the building's drainage system.
