Blocked gutters are the quiet cause of some of the most expensive damage a house suffers — and almost all of it is preventable. Here’s what’s really going on up there, and how often the job needs doing in Sydney.
Why gutters block
It isn’t just leaves. In Sydney, gutters fill with a mix of gum leaves and bark, wind-blown seed, roof grit that washes down from tiles, and — near the coast — salt and sand that packs into a hard silt at the base. That silt is the real problem: it doesn’t blow clear, it consolidates, and it holds water against the back of the gutter and the fascia behind it.
What overflow actually damages
When water can’t get to the downpipe it sheets over the edge and back under the roof line. Over time that means rotted fascia and eaves, rusted-through gutters, water in the ceiling, and on sloped blocks, erosion and pooling where the overflow lands. By the time you see a stain on the ceiling, the damage has been happening for months.
How often is enough
For most Sydney homes, twice a year — once heading into the storm season in late spring, once after the main leaf drop — keeps gutters working. But it depends heavily on trees: a property under heavy gum or paperbark canopy may need three or four cleans a year, while an exposed coastal home with little tree cover might manage on one plus a check. Bushland-backing homes also carry a fire-safety reason to keep gutters clear of dry litter.
Clearing vs flushing
Scooping the debris out isn’t the whole job. Downpipes block at the mouth and midway, and a gutter that looks clear can still fail to drain. A proper clean clears the full run and flushes every downpipe from the blockage up, then checks the flow.
