Are your gutters ready for a bushfire?

Are your gutters ready for a bushfire?

by | Sep 22, 2023 | Bushfire & Ember Guard

As we find ourselves in the heart of bushfire season, it’s crucial to ask: are you truly prepared? The threat of ember attacks, the risk of bushfires, and dangers posed by overhanging trees are all too real. Yet, many of us may not have given these threats the consideration they need.

Assessing Bushfire Risk

Bushfires are unpredictable by nature, but certain factors can increase your risk. For instance, homes surrounded by thick vegetation or located on slopes face a higher risk due to the speed at which fires can travel uphill. Branches hanging over your house can present a significant risk during bushfire season. These branches, especially if dry, can easily catch fire and drop embers onto your roof.

Understanding Ember Attacks

Ember attacks can be a significant factor in the spread of bushfires. Embers, carried by wind, can travel long distances, causing fires to start in locations far from the main fire front. Your home could be at risk even if it’s not immediately adjacent to the burning area.

Inside your gutters

Dry leaves in gutters are a source of fuel that can be ignited by bushfire embers. Unprotected gutters are the main reason for this problem; however, poorly-specified gutter mesh can also leave you vulnerable to this threat by allowing leaves to enter your gutters.

Inside your building

Embers can get inside your building through small gaps between your roof, gutters and fascia. They can then start a fire when they land on insulation or other fuel sources. Only a gutter mesh made from materials approved to the Australian standard AS3959-2009 such as corrosion-resistant steel, and with an aperture of 2mm or smaller, will keep embers out of your gutter.

 

Bushfire compliance and ember guard compliance are different. Do you know the difference?

Bushfire Compliance

According to AS3959-2009, gutter guards are optional for new buildings in bushfire-prone areas. However, if you choose to use them the standard states that “if installed, gutter guards shall be non-combustible”.

Ember Guard Compliance

Ember guards are mandatory for all new buildings in areas with a BAL of 12.5 or higher. They are used to “seal” gaps greater than 3mm, such as gaps around your roof sheeting, to stop burning embers getting into your building.

Blue Mountain Gutter Mesh 2mm steel is ember guard compliant for all BALs (12.5, 19, 29, 40 and FZ) and our 2mm aluminium is ember guard compliant for BALs 12.5, 19 and 29.

 

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.

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: 

✅ Install ember guards to your gutters
