Why this matters now
California's first heavy rains of the season usually hit in November. By the time water is overflowing your gutters and pouring down your siding, it's too late to schedule a replacement before winter. The right time to inspect is right now — late spring through summer.
The 5-minute homeowner inspection
Walk the perimeter of your home and look up at the gutters. You don't need a ladder for this — most warning signs are visible from the ground.
Sign 1: Visible stains or streaks on siding below the gutters
What you're seeing: Vertical dark streaks running down from the gutter line. Sometimes white salt deposits, sometimes brown rust stains.
What it means: Water is overflowing or leaking at that location. Could be a clog, could be a leak, could be the gutter is full of standing water.
Urgency: Medium. Investigate within 30 days.
Sign 2: Gutter is pulling away from the fascia
What you're seeing: A visible gap between the back of the gutter and the wood fascia board behind it.
What it means: The fascia is rotted, or the hangers have failed. Either way, the gutter will fall during a heavy rain — usually taking a piece of fascia with it.
Urgency: High. This will fail in the next storm.
Sign 3: Sagging between hangers
What you're seeing: The gutter "smiles" downward between the brackets. From the street it looks like a wavy line instead of straight.
What it means: Either the gutter is constantly full of water (drainage problem) or the metal has fatigued. Both indicate end of life.
Urgency: Medium-high. Replace within 6–12 months.
Sign 4: Rust spots on the gutter exterior
What you're seeing: Reddish-brown spots, especially at joints, end caps, and around fasteners.
What it means: The protective finish has failed and the metal is corroding. On steel/galvanized gutters, this is structural. On aluminum, it's usually surface oxidation from poor finish quality (common on cheap installations).
Urgency: Medium-high if galvanized (replace). Low if aluminum (cosmetic).
Sign 5: Plants growing in or on the gutters
What you're seeing: Visible weeds, grass, or even small trees growing in your gutters from the ground.
What it means: The gutters have been holding water and organic matter for at least a full season. The fascia behind them is almost certainly rotting.
Urgency: High. Plan replacement + fascia inspection.
Bonus signs (if you do climb a ladder)
- Standing water 30 minutes after rain stops
- Gutters fill with debris within weeks of cleaning
- Fasteners (screws or spikes) visibly working themselves out
- Visible holes or cracks at joints
- Soft, spongy wood when you press the fascia board
Inside-the-home signs
- Stains on ceiling near exterior walls. Water making it past the gutters into the home.
- Basement or crawlspace moisture. Improper drainage at downspouts is concentrating water at the foundation.
- Erosion or mulch displacement at base of walls. Overflow from gutters is washing landscape away.
What to do next
If you see 2 or more of the signs above, schedule an on-site assessment. Most contractors (us included) provide free inspections — get 2–3 opinions and compare written quotes.
If you see only one mild sign and your gutters are under 10 years old, you probably just need a cleaning and tune-up ($200–$500). Don't let a salesperson talk you into replacement on a system that has years of life left.
