Signs to use alongside cleaning dates.
Report plants in the channel, leaves you can see and water escaping over the edge. Say whether the issue appears during ordinary rain or only heavier downpours. A joint drip may concern damage rather than debris. Fallen moss pieces can be among the accumulated material, but gutter clearance is separate from removing moss on the roof. If nothing is visible, explain that rather than inventing a blockage to justify a visit.
Keep the earlier clearance date beside the section it covered. A front gutter cleaned recently and an older rear-gutter concern have different histories. The distinction helps with future checks without needing an elaborate maintenance record or a guessed cleaning interval.
