Short Answer
Maintenance may include debris removal, inspection, checking hangers, checking seams, checking downspouts, verifying drainage, and checking for overflow.
Detailed Explanation
Gutter maintenance is essential for proper function. Key maintenance tasks include: removing leaves, twigs, and debris from gutters (typically twice a year — spring and fall, or more often if the home has many trees); checking gutter hangers for security and tightening or replacing loose ones; checking seams and joints for leaks; checking downspouts for clogs and proper drainage; verifying that water flows freely through the system and doesn't overflow; checking that downspouts discharge away from the foundation; and inspecting for sagging, damage, or rust. Gutter guards can reduce the frequency of cleaning but don't eliminate it. Neglected gutters cause fascia rot, foundation water problems, ice dam contribution, and landscape erosion.
Why It Matters
Regular gutter maintenance prevents costly water damage to the foundation, fascia, and landscaping. It's one of the most important — and most neglected — home maintenance tasks.
