Debris can hide the condition of a drain and surrounding membrane. Clearing the visible material is an initial step, not a complete assessment of the detail. Connections and nearby roofing may still need inspection.
What to do next
Ask for before-and-after photographs and notes about any damage revealed. Keep drainage cleaning separate from membrane repairs and downstream plumbing work. A location-based record helps identify recurring obstruction and whether additional changes should be evaluated.
