What Causes Gutters to Overflow?
Overflow happens when water can’t flow properly through your gutter system.
This is usually due to:
- Blockages
- Poor drainage
- Structural issues
Most Common Causes of Overflow in Auckland
🍂 1. Blocked Gutters
The #1 cause of overflow.
Gutters fill with:
- Leaves
- Twigs
- Dirt

This leads to:

- Blocked drainage
- Overflow
🚿 3. Blocked Downpipes
Even if gutters look clean:
- Downpipes may be clogged
- Water backs up
- Overflow occurs
🌧️ 4. Heavy Rainfall
Auckland’s rain can:
- Overwhelm partially blocked gutters
- Expose hidden problems
🧱 5. Poor Gutter Slope
Gutters need correct angle to drain.
If not:

- Overflow increases
🌊 6. Coastal Conditions
Salt and moisture:
