A planned drainage review can identify visible obstructions and defects before heavier use exposes them. It should cover the actual drainage arrangement and document limitations. The visit is a maintenance step, not a guarantee against all future overflow.
What to do next
Provide prior overflow locations and service records. Ask for findings by outlet or roof section. Track recommended repairs separately from completed cleaning so known defects remain visible after routine maintenance is marked finished.
