Why gutters cause leaks
When gutters block or fail, water backs up under the roof edge and over the fascia instead of draining — soaking eaves, walls and ceilings. Clearing and realigning gutters is one of the cheapest bits of leak prevention there is.
Repair or replace
Rust holes, sagging runs and failed joints can often be repaired if the gutters are otherwise sound. If they're widely corroded or undersized for Sydney's downpours, replacement with larger Colorbond profiles is the better long-term fix.
Frequently asked questions
How often should gutters be cleaned?
At least once or twice a year, and more often under heavy tree cover — before storm season especially.
Can blocked gutters really cause a roof leak?
Yes — it's one of the most common causes, as water backs up under the roof edge in heavy rain.
Are leaf guards worth it?
Under heavy tree cover they cut cleaning frequency and overflow risk — a roofer can advise if they suit your roof.
