Learn about recent updates to make your roof more fire-resistant in areas prone to wildfires. 

Wildfires have become an increasing concern for homeowners, especially those living near wildland areas in the Western U.S. As the risk of wildfires grows, so does the importance of fire-resistant roofing materials. A recent WSRCA technical bulletin highlighted new building code requirements aimed at addressing wildfire concerns, particularly for steep-slope roofing systems. If you live in an area prone to wildfires and are considering updating or replacing your roof, it’s essential to understand these changes and how they impact your home’s safety. This article breaks down the key points of these updates and explains why discussing your options with a trusted roofing contractor is so important. 

What homeowners need to know about fire-resistant roofing 

The updated building codes primarily focus on preventing wildfires from igniting combustible roof decks. One of the most critical changes is the requirement for roofing underlayments to meet stringent fire resistance standards. Specifically, these underlayments must comply with ASTM E108 Class A standards, ensuring they provide maximum protection against fire. 

But what does this mean in simple terms? Essentially, the underlayment is the layer of material between your roof deck (the structural surface) and your shingles. In the event of a wildfire, embers can travel miles and land on your roof. If your roof has gaps between the shingles and the underlayment, these embers can ignite the roof deck, leading to a fire. The new code changes aim to minimize this risk by requiring underlayments that are resistant to high heat and prevent embers from penetrating the roof structure. 

What do you need to do about these changes? 

Wildfires can cause significant damage in a matter of minutes, and your roof is one of the first lines of defense. A fire-resistant roof can protect your home from ignition and help prevent the spread of fire. 

It’s important to note, however, that these building code changes are recent, which means not all roofing materials currently available may meet the new standards. This is why it’s crucial to talk to your roofing contractor before making any updates or investments in a new roof. They can help you navigate these new requirements and ensure that your home is as protected as possible. 

Common questions homeowners might have 

  • Are asphalt shingles fire-resistant?
    Yes, but not all asphalt shingles are created equally. The most fire-resistant shingles carry a Class A rating, the highest level of fire resistance. These shingles are designed to withstand severe fire exposure and are less likely to ignite or spread flames. 
  • What does Class A fire rating mean?
    A Class A rating indicates that shingles are highly resistant to fire. They are tested to ensure they don’t easily ignite, spread flames or suffer damage under severe fire conditions. All asphalt shingles manufactured by PABCO Roofing Products carry a Class A fire rating. 
  • Will my current roof meet the new standard? 

This depends on the materials and installation of your existing roof. If your roof was installed before these updates, it’s possible that it may not fully meet the new fire-resistance requirements. Consult with a roofing contractor to assess your roof and determine any necessary updates. 

  • What if my roofing materials aren’t available locally yet? 

The new code changes are still being adopted, so it’s possible that not all materials that meet the requirements are readily available in your area. This is another reason to work with a knowledgeable contractor who can help source the appropriate materials or find alternatives to comply with the new standards. 

Bridging the gap between code updates and available materials 

One of the challenges that homeowners might face is the gap between these new code requirements and the availability of compliant materials. As the technical bulletin mentions, while the codes are in place, some jurisdictions might not be fully aware of them, and not all manufacturers have products that meet these new standards readily available. This gap can create confusion and frustration, especially if you’re trying to ensure your home is as fire-resistant as possible. 

The best way to bridge the gap is to stay informed and be proactive. Make sure your contractor is up to date on the latest building codes and understands the specific requirements for your area. They should be able to guide you in selecting materials that not only meet the new standards but also provide the best protection for your home.
