Short Answer
Yes, maintaining functioning drainage is important before periods of heavy rain, leaves, snow and freezing conditions.
Detailed Explanation
Gutter cleaning before winter is essential. Clogged gutters in winter cause multiple problems: water that can't drain through clogged gutters overflows and runs behind the gutters, wetting the fascia and potentially causing rot; water in clogged gutters can freeze, creating ice that damages gutters and contributes to ice dams; and the weight of debris plus ice can pull gutters loose from the fascia. Before winter, gutters should be cleaned of all leaves, twigs, and debris. Downspouts should be checked for clogs and proper drainage. Gutter hangers should be checked for security. If the home has many trees, gutter guards may be worth considering to reduce debris accumulation. Clean, functioning gutters before winter prevent many common winter water problems.
Why It Matters
Clean gutters before winter prevent ice damage, fascia rot, and ice dam contribution. It's one of the most important fall maintenance tasks.
