October might bring beautiful fall colours, but it also signals the start of heavy rain, wind, and dropping temperatures. For homeowners across Metro Vancouver, this is the make-or-break moment for your gutters. When water freezes, expands, or overflows, even minor issues can lead to serious damage: ice dams, foundation cracks, roof leaks, or even structural rot.
Before winter weather hits, take a few minutes to check for these telltale signs your gutters might not survive the season.
- Sagging or Pulling Away from the Roofline
If your gutters are sagging or separating from your home, it’s often a sign that they’re overloaded, usually from debris, standing water, or weakened fasteners. As temperatures drop, any trapped water can freeze and expand, worsening the problem and potentially causing gutters to detach altogether.
Tip: If you notice uneven lines or visible gaps between your gutters and fascia, book a professional inspection right away.

Small leaks and rust spots are easy to ignore in dry weather, but once winter hits, they become gateways for bigger problems. Leaking joints can channel water behind your siding or under your roof, leading to mold and water damage. Rust is a clear indicator that your gutters are aging and may soon corrode through completely.

If water spills over the edges during heavy rain, it means your gutters or downspouts are clogged or undersized for your roofline. Overflowing water doesn’t just wash away soil, it can erode your foundation, flood basements, and damage exterior walls.
Quick Fix: Clear out leaves and pine needles this month, and consider installing gutter guards before winter sets in.

Water stains or peeling paint near your gutters are subtle but serious clues that water is escaping where it shouldn’t. Over time, that trapped moisture can seep into wood, causing rot or mildew, both of which are harder, and more expensive, to fix once temperatures dip below freezing.
Tip: Walk around your home after a storm to check for discolouration or streaks. It’s a simple way to spot hidden drainage issues early.

- Ice Dams or Icicles Forming in Early Winter
If your gutters routinely develop icicles or ice dams, your system may not be draining properly. Ice buildup adds weight and pressure, increasing the risk of gutter collapse, and can cause meltwater to back up under shingles, leading to roof leaks.
