Fire Resistant Construction Strategies for US Contractors

As wildfires become more frequent, widespread, and destructive, contractors nationwide must be ready to build homes that are not only beautiful and functional—but resilient in the face of growing fire threats.

With more than a million acres and 1,716 structures destroyed by fires in 2024 alone, California homebuilders are already investing more in using fire-resistant materials in construction.

From the Western mountains to the Southern plains, the wildfire risk is increasing across regions not previously known for large-scale fires. Whether you’re working in California, Colorado, Texas, Florida, or beyond, fire-resilient construction isn’t a future concern—it’s today’s standard. 

Why Fire-Resistant Construction Matters 

In 2025, wildfires destroyed more than 16,000 structures in Southern California alone, costing an estimated $275 billion in damage, according to AccuWeather. And while California has long been the epicenter of wildfire awareness, states across the South and West are catching up quickly. 

Climate change, prolonged droughts, and rapid development into wildland-urban interface (WUI) zones mean more structures are at risk than ever before. For contractors, this presents both a challenge and an opportunity to lead with smarter, safer construction practices. 

Key Tips for Fire-Resistive Home Construction 

No matter where you’re building, these proven strategies can significantly improve a home’s chance of surviving a wildfire: 

1. Use Class A Fire-Rated Roofing 

Roofs are the most vulnerable part of a home during wildfires. Choose asphalt fiberglass shingles, metal, clay, or concrete tiles that resist ignition and heat. Avoid flat roofing where embers can collect. 

2. Install Non-Combustible or Ignition-Resistant Siding 

Materials like fiber cement, stucco, brick, or metal offer excellent protection. Ensure proper installation to seal any gaps where embers could ignite underlying components. 

3. Upgrade to Ember-Resistant Vents 

Vents are essential for airflow—but dangerous during a wildfire. Install corrosion-resistant 1/8-inch metal mesh and ember-resistant designs to maintain ventilation while blocking fire. 

4. Select Durable, Fire-Safe Windows 

Dual-pane windows with at least one tempered glass pane can withstand fire longer than traditional single-pane versions. Research shows these can last 2–3 times longer in wildfire conditions. 

5. Avoid Flammable Decking 

Traditional wood decks can become fuel for a wildfire. Use Class A-rated composite decking or non-combustible options like metal and concrete to limit ignition risk. At the very least consider chemically-treated wood which resists ignition and can slow down the combustion process.

6. Plan for Defensible Space 

Create 30 to 100 feet of defensible space by clearing dry vegetation and using fire-resistant landscaping materials. This buffer zone can stop or slow fire spread toward the structure. 

7. Consider Fire Sprinkler Systems 

Especially in high-risk zones, residential fire sprinklers can save lives and properties by suppressing fires before they spread. 

Learning from California: A National Model 

California has led the way in fire-resistive building codes, notably through its Chapter 7A regulations and adoption of the International Wildland-Urban Interface Code (IWUIC). Homes built under these standards are significantly more likely to survive a wildfire. 

Other states—especially those now experiencing more frequent fires—can benefit by adopting similar codes and practices. Contractors across the country should stay current with local building codes and push for stronger standards when necessary.
