7 Warning Signs Your Gutters Need Cleaning Right Now

Most gutter problems don't announce themselves loudly — they show up as small visual cues that are easy to walk past. Here are the seven signs worth actually stopping for, ranked by urgency.

1-2. Sagging or Pulling Sections (Highest Urgency)

If a section of eavestrough is visibly pulling away from the fascia board or sagging in the middle, this isn't a cleaning issue alone — it's a sign the weight of trapped debris and water has strained the hangers. Left alone, especially through a Kamloops freeze-thaw cycle, this section can detach entirely. We go deeper on what this specifically signals in Sagging or Pulling Gutters: What It's Telling You About Your Home.

3. Water Marks on Siding Below the Gutter Line

Streaking or discoloration on siding directly under a gutter run means water has already been overflowing, not just building toward it. This is active damage in progress, not a future risk.

4. Plants or Moss Growing in the Trough

Seeds land in wet, compacted debris and take root — meaning if something's growing in your gutter, that debris has been sitting undisturbed for months, likely through at least one full season. Full explanation in Why Plants Are Growing in Your Gutters (And What It Means).

5. Overflowing During Rain

Water sheeting over the gutter edge during rainfall, rather than draining through the downspout, is one of the clearest and most urgent signals — detailed in Overflowing Gutters During Rain: What It Signals and How Urgent It Is.

6–7. Visible Debris and Gutter Staining (Lower Urgency, Still Worth Addressing)

These are early warnings. Visible leaves or needles from ground level, or staining on the gutter's outer face from water sitting rather than flowing, indicate buildup that hasn't yet caused overflow — the easiest and cheapest stage to address.
