How often should you clean your gutters?

Gutters are easy to forget until water pours over the edge in a downpour or a stain appears on the ceiling. Keeping them clear is one of the simplest jobs that protects your home. This guide covers how often to clean them, the warning signs to look for, and when it makes sense to book a gutter cleaner instead of climbing up yourself.

Why clean gutters matter

Gutters and downpipes carry rainwater off the roof and away from the house. When leaves, twigs and dirt build up, that water has nowhere to go.

The NSW State Emergency Service warns that blockages can trap water and cause it to overflow under the eaves into your roof cavity. That's how a blocked gutter can turn into a leak inside the house, damaged plaster or a stained ceiling.

Dry leaves in gutters are also a fire risk. The NSW Rural Fire Service lists cleaning leaves and twigs out of your gutters as a basic step in preparing your home for bush fire, and its home preparation guide notes that burning embers landing in debris-filled gutters can set a home on fire.

If you collect rainwater, clean gutters also help keep dirt and debris out of the tank. The NSW Government suggests keeping the roof catchment clear of overhanging branches and fitting first-flush diverters, leaf stoppers on downpipes and gutter guards.

So, how often should you clean them?

There's no single rule that suits every home. The emergency services agencies all give the same general advice: clear your gutters, downpipes and drains regularly, and especially before storm season and bushfire season. VICSES and the Tasmania SES both include it in their storm preparation tips.

How often "regularly" means for you depends on a few things:

• Trees nearby. Homes surrounded by gum trees, palms or other big trees drop far more into the gutters than a house in an open street. These homes usually need checking more often.
• Bushfire risk. If you live on or near bush land, keeping gutters clear through the warmer months matters more. You can check whether your property is on bush fire prone land through the NSW RFS website or your state's fire service.
• Storm season. In many parts of Australia, storms are more common in the warmer months. A clean before then gives water a clear path when heavy rain arrives.
• Roof design. The NSW RFS notes that upper-storey gutters make debris removal more difficult. Two-storey homes are often the ones people put off, so plan ahead rather than leaving it to the last minute.
• Gutter guards. Guards can cut down how much debris gets in, but they still need checking. Leaves and dirt can collect on top of them or around the edges.

A practical approach is to check your gutters at least before storm and bushfire season, then again after big winds or heavy leaf drop. If you notice a problem in between, don't wait for the next scheduled clean.

Signs your gutters need cleaning

You don't always need to get on a ladder to spot a problem. Look out for:

• water overflowing from the gutter during rain
• plants, grass or seedlings growing out of the gutter
• sagging sections or gutters pulling away from the fascia
• stains or water marks on the eaves, fascia or outside walls
• puddles or erosion along the base of the house below the gutter
• downpipes that gurgle, drip slowly or don't flow at all
• birds or pests nesting in the gutter line

If you see water marks on an inside ceiling, that can mean water has already got into the roof space. It's worth getting a roofer or plumber to check the cause, as the issue may not just be the gutters. Our guide on signs of a hidden water leak explains what else to look for.

DIY or call a gutter cleaner?

Plenty of people clean their own gutters on a single-storey house. But falls from ladders are a real risk at home. The ACCC's Product Safety Australia says that on average more than 30 Australians die each year after falling from a ladder, and that most men injured or killed were at or nearing retirement.

If you do it yourself, the ACCC and NSW Health's Agency for Clinical Innovation recommend some simple precautions:

1. Choose the right ladder for the height and check it's in good condition.
2. Set it up on firm, level ground and lock any braces or spreaders.
3. Have someone hold the ladder at the base while you work.
4. Don't stand too high. Stay below the second step from the top of a stepladder, or the third rung from the top of an extension ladder.
5. Don't over-reach. Keep your body between the side rails and move the ladder instead.
6. Skip it in wet or windy weather, and keep well clear of powerlines.

NSW Health also suggests alternatives such as hiring a tradesperson, getting help from someone else, or using gutter guards to reduce how often the job needs doing. Older people and people with disability may be eligible for help with home maintenance through their local council.

When a professional makes sense

Consider booking a gutter cleaner, roofer or handyman if:

• your home is two storeys or the roof is steep
• you're not comfortable working at height
• the gutters are badly blocked, damaged or sagging
• you'd like the roof checked for broken tiles or loose sheets at the same time
• you want gutter guards installed

Prices vary with the size and height of the house, how blocked the gutters are and whether extras like downpipe flushing or guard installation are included. Ask for two or three written quotes so you can compare what's covered. Our guide on how to compare tradie quotes can help.
