Leaking Gutters
Gutters that leak at joints, end caps, or through rust holes deposit water against fascias, eave linings, and wall cladding rather than routing it to downpipes and stormwater. Persistent wetting creates conducive conditions for fungal decay, borer activity, and termite attack at the roof perimeter - some of the most expensive structural repairs on a Perth home.
Severity rationale
The modal score across 887 observations is 3, with 684 findings (77%) at score 3. Score 2 accounts for 194 findings (22%) and typically reflects minor joint leaks or early-stage rust with no visible downstream damage. Score 4 is present in 9 observations (1%) where active leaks have caused measurable fascia or lining damage. No score 1 or 5 findings exist - the floor of 2 confirms our inspectors treat leaking gutters as more than a cosmetic issue in all cases. The score rises toward 4 when fascia timber shows softness or when moisture is tracking toward framing.
Causes
- Corrosion through gutter steel from long-term ponding of debris-laden water
- Rust holes developing at low points where debris accumulates and holds moisture
- Failed or missing joint sealant at gutter union points and end caps
- Lack of routine cleaning allowing debris to build up and accelerate corrosion
- Impact damage or sagging creating low spots that retain water and corrode
Symptoms to look for
- Rust staining or active rust penetration visible on gutter sections
- Water dripping from gutter joints or end caps during or after rain
- Staining, paint breakdown, or timber softness on fascias and eave linings directly below leaks
- Moisture accumulation at the wall-to-roof junction creating termite conducive conditions
- Visible water stains on external cladding from overflow or drip paths
Remedies
- Engage a roof plumber to assess whether affected gutter sections require patch repair or full replacement
- Replace corroded gutter runs rather than patching - rust holes typically indicate end-of-life for the full run
- Finish replacement gutters in a protective coating (Colorbond or powder coat) to slow future corrosion
- Clear debris and flush all gutters at the time of repair; schedule annual cleaning to prevent recurrence
- Inspect and repair fascia and eave lining softness before re-hanging new gutters

Worth asking our inspector about this specifically.
Leaking gutters are a moderate priority - the water they deposit against fascias and linings sets up rot and termite conditions over years, not weeks. Get a roof plumber to assess and quote before the next wet season.
