Bushfire-Proofing Your Gutters

Bushfire-Proofing Your Gutters

by | Dec 13, 2021 | Bushfire & Ember Guard

Australia’s climate comes with many fantastic benefits.  

A beachside lifestyle, mild winters and plenty of opportunities to soak up Vitamin D are just some of the many advantages of life in the land down under.  

But, as if it was balancing out these benefits, our climate also brings a particularly nasty threat each summer: bushfire. 

 

Bushfires & ember attack 

Most people understand that your home can be threatened by the arrival of a bushfire front.  

However, what you may not realise is that many homes burn down long before the bushfire front reaches them – if it reaches them at all.  

In fact, over 85% of homes that burn down during a bushfire ignite because of ember attack.

Ember attack occurs when burning debris or embers fly ahead of the bushfire front, settling on, around or in your home and setting it alight.  

Gaps around your home, garden plants, and drying leaves and debris in your gutters all increase your risk of fire due to ember attack. 

 

Gutters as a line of defence 

Because drying leaves and debris in your gutters are a common source of fuel for ember fires, your gutters can form a key line of defence in equipping your home to withstand ember attack and destruction by fire.

Regular gutter cleaning is one obvious way to keep your gutters clear of bushfire fuel.

However, regular gutter cleaning comes with its own costs.

Paying a professional to clean your gutters every 3 months can cost hundreds of dollars, while cleaning them yourself can be dangerous and time consuming – especially if you’re under stress and rushing to prepare your gutters for an approaching bushfire.

Because of this, a better approach to bushfire-proofing your gutters is to use gutter mesh to prevent most leaves and debris from entering your gutters in the first place.

Gutter mesh  

Over-the-gutter mesh such as Blue Mountain Co Gutter Mesh forms a physical barrier over your gutters that’s designed to keep leaves, pests, debris and other nasty items out of your gutters.  For eaves and fascia gutters that sit on your roof’s edges, further protection is provided by the slope that’s created as the gutter mesh is angled in line with your roof, making it easier for any leaves or debris that settle on top of your gutter mesh to blow away.

Bushfire standards mandate that any gutter guard such as gutter mesh on a new home in a bushfire-prone area must be made from non-combustible materials. In addition to this, we also suggest you choose a mesh with a maximum 2mm aperture (hole size), as this is the recommended size for ember guards, which are designed to keep embers out too.

That’s why at Blue Mountain Co Gutter Mesh, we recommend our 2mm steel gutter mesh for use as a gutter guard on homes in bushfire prone areas.

Defending your home 

There are many steps you can take to help defend your home against the threat of bushfire.  

A number of these steps are outlined in the Australian Standard for building in bushfire-prone areas. This standard explains the rules for gutter guard and ember guard-compliant mesh in greater detail, and is an important resource for anyone considering building a new home.  

You can also contact your local fire authority to learn more and ask for direction to other resources.

The Growing Bushfire Threat 

Australia’s bushfire seasons are becoming more intense and unpredictable. The devastating 2019–2020 Black Summer fires burned over 24 million hectares, destroyed more than 3,000 homes, and impacted communities across the country (Statista, 2023). And the risks are only increasing: 

  • Fire seasons are starting earlier and lasting longer. 
  • Extreme fire weather is becoming more frequent. 
  • The annual area burned is growing. 

Prolonged droughts, rising temperatures, and drier landscapes are creating the perfect storm for fires to ignite and spread rapidly (Bowman et al., 2017). In some regions, fire seasons are now over a month longer than they were 35 years ago (NASA, 2023). 

Your Gutters: A Hidden Fire Risk 

When it comes to bushfire preparedness, many homeowners focus on clearing vegetation around their property. But one critical weak spot is often overlooked—gutters.This phenomenon, known as an ember attack, is responsible for up to 90% of homes lost in bushfires (Leonard et al., 2016). Dry leaves and debris in gutters provide the perfect fuel, allowing fire to spread to the roof and into the home within minutes. 

Gutter Protection: A Simple Yet Powerful Defence 

 
Investing in effective gutter protection is a key step in reducing your home’s bushfire risk. At Blue Mountain Gutter Mesh, we offer premium ember guard-compliant gutter mesh, designed to defend against ember attack. Our 2mm steel and aluminium gutter mesh options meet Australian Standard AS3959-2018 for ember guard compliance while preventing flammable debris buildup in your gutters—a critical factor since up to 90% of bushfire-related property losses stem from ember ignition. Crafted from non-combustible, corrosion-resistant materials, our mesh keeps embers and leaves out, safeguarding your home. 
 
2mm Steel Gutter Mesh: Ember guard compliant for all BALs (12.5, 19, 29, 40 and Flame Zone) 

2mm Aluminium Mesh: Features a woven edge for extra durability and is ember guard compliant for BALs 12.5, 19 and 29. 

5 Signs Your Gutters Need Protection Now 

  1. Leaves and debris constantly build up. 
  2. Water spills over during heavy rain. 
  3. Your gutters are sagging or pulling away. 
  4. Stains or water damage appear on exterior walls. 
  5. You live in a bushfire-prone area. 

Bushfire Readiness Checklist:
