Bushfire season is one of the most dangerous times to have dirty gutters. Dry leaves, twigs, and debris sitting in your roof gutters are essentially a pile of kindling waiting for a spark. And during a bushfire, that spark can travel kilometres before it lands on your roof.
Properly cleaning your gutters is a simple but significant way to minimise your risks during bushfire season.
Most homeowners think about gutters during heavy rain. But ahead of bushfire season, your gutters deserve just as much attention, if not more.
During a bushfire, burning embers are carried by the wind far ahead of the fire front. According to the NSW Rural Fire Service, those embers can land directly in roof gutters and ignite any accumulated debris. Once your gutters catch fire, the flames spread rapidly to your roof cavity and into the home. The NSW RFS specifically lists gutter cleaning as one of the top five steps every homeowner should take before bushfire season begins.
Not every property carries the same level of risk, but some are clearly more vulnerable than others. If your home ticks any of these boxes, gutter cleaning before bushfire season is non-negotiable:
Strata properties and commercial buildings carry additional responsibility. Debris accumulates across larger roof surfaces, and a gutter fire can affect multiple occupants.
Aim to complete your gutter cleaning by late September, before the Bush Fire Danger Period officially begins on 1 October in NSW. Waiting until October is leaving it too late, as conditions can escalate quickly, and many professional services book out in the lead-up to the season.
If you're in an area with heavy tree coverage, a second clean mid-season (around January) is also worth considering. Autumn leaf fall adds another layer of risk, so a post-summer clean before the following winter isn't a bad idea either.
Use this checklist to make sure your home is fully prepared.
Remove all leaves, twigs, seed pods, and built-up sediment from every section of guttering. Pay particular attention to corners and sections closest to large trees. Even a small amount of dry debris can ignite from a single ember.
Roof valleys (the V-shaped channels where two roof sections meet) are notorious for trapping leaves. They're often overlooked during basic roof gutter cleaning, but are a prime ember landing zone. Make sure these are fully cleared.
Blocked downpipes cause water to back up into gutters, keeping debris wet longer during rain but leaving it bone dry during hot spells. Flush every downpipe with a hose to confirm water flows freely.
Look for cracked, sagging, or pulling-away sections of guttering. Gaps between gutter joins allow embers to enter the roof cavity directly. Any damage found should be repaired before fire season. Consider booking a gutter maintenance and repair service at the same time as your cleaning.
Loose debris sitting on the roof itself, particularly around ridge caps, in valley sections, and near penetrations like skylights, should be swept or blown clear. Embers landing on a debris-covered roof can ignite before they even reach the gutters.
Tree branches hanging directly over your roof constantly drop debris. Trim them back so they're well clear of the roofline. The NSW RFS recommends this as one of the top five bushfire preparation actions for every property owner.
Birds and possums often nest in gutters during warmer months. Nesting material is extremely dry and combustible. If you find a nest, have it safely removed as part of your professional roof gutter cleaning service.
Clean gutters are a great start, but gutter guard installation can provide long-term protection by preventing debris build-up in the first place. Ember-compliant gutter mesh (meeting Australian Standard AS3959:2018) also physically blocks embers from entering your roof space, significantly reducing ignition risk.
