Getting ready for Perth's wet season: gutter and downpipe maintenance

Perth’s wet season has a way of finding every weakness in a gutter system that’s been quietly neglected all year. A bit of maintenance beforehand is one of the cheapest ways to avoid water finding its way into your roof cavity, walls, or foundations when the rain actually arrives.

Why this matters more than people expect

Gutters that are blocked or damaged don’t just look messy, they stop doing their actual job, which is moving water away from your roofline and foundations. Overflowing gutters can send water running down external walls, pooling near foundations, or backing up under roof tiles or sheeting, none of which are cheap problems to fix once they’ve been happening unnoticed for a season or two.

A practical pre-wet-season checklist

• Clear leaves and debris. Remove built-up leaves, twigs and dirt from gutters and check that downpipes aren’t blocked at the entry point.
• Check the fall. Water should flow toward the downpipes, not pool in low spots. Standing water after a light rain is a sign the fall isn’t right somewhere along the run.
• Look for rust, holes or sagging. These indicate the gutter itself needs repair or replacement, not just a clean.
• Check gutter brackets and fascia. Loose brackets or a rotting fascia board behind the gutter can cause sagging even if the gutter itself is otherwise fine.
• Test downpipe flow. Run water through with a hose if you can, to confirm it’s actually reaching the ground or stormwater connection without blockage.

When to call a plumber instead of doing it yourself

Ground-level, single-storey gutter clearing is a reasonable DIY task for many homeowners, done carefully with a stable ladder. Once you’re dealing with a steep roof, second storey access, or you’ve spotted actual damage like sagging, rust or gutters pulling away from the house, it’s safer and often cheaper long-term to bring in a plumber who can assess whether it’s a maintenance job or a repair.

Sign	What it suggests	DIY or professional
Leaves and light debris	Routine seasonal buildup	DIY on single storey, careful ladder use
Water pooling after light rain	Fall issue somewhere in the run	Professional assessment
Rust, holes or visible corrosion	Gutter material failing	Professional repair or replacement
Sagging or pulling away from fascia	Bracket or fascia issue	Professional assessment

Don’t forget the stormwater connection

Gutters and downpipes are only half the system. Check where your downpipes discharge, whether that’s into a stormwater drain, a soakwell, or across the ground, and confirm that connection point isn’t blocked with leaves, sediment or a collapsed soakwell that’s stopped absorbing water properly. A gutter and downpipe that are perfectly clear won’t help much if the water has nowhere to go once it reaches ground level, and a blocked or failing stormwater connection is one of the more overlooked causes of pooling around foundations during heavy rain.

Making it a habit

Doing this check annually, ideally in the lead-up to the wet season, catches small issues while they’re still cheap to fix. Leaf guard mesh can reduce how often you need to clear debris, particularly for homes under established trees, though it doesn’t remove the need for an occasional check altogether.

It’s worth pairing the gutter check with a quick look at your roof itself while access is already sorted, since loose or lifted tiles and sheeting are often spotted incidentally during gutter work and are far cheaper to fix before the first heavy downpour than after water has already found its way in. A five-minute walk around the property after the check, looking for anything obviously out of place along the roofline, rounds out a proper pre-wet-season once-over without adding much time to the job.
