Roof drainage systems collect and direct water from a roof through features such as slopes, gutters, drains, scuppers and downspouts.
What this means at your property
A leak or overflow may involve a blockage, a damaged component or a drainage detail rather than only the roof covering. The discharge point also matters because moving water off a roof does not guarantee it moves safely away from the building.
What should an inspection cover?
Ask which collection points, outlets and discharge paths were examined and whether access limited the findings. Keep observations from heavy rain and previous maintenance available to help the roofer investigate recurring conditions.
