So, how do Wildfires begin in the United States?

Wildfires begin in the United States due to natural causes or human negligence. To put it simply, most wildfires begin when a heat source comes in contact with vegetation (primarily dry vegetation), and oxygen is present. For any fire to burn, it needs three things: heat, fuel, and oxygen (this is known as the Fire Triangle).

Wildfires often start due to human negligence, which accounts for over 75% of wildfire outbreaks in the United States. Activities such as leaving campfires unattended, improperly disposing of burning debris, and using fireworks irresponsibly are common culprits. Sparks from faulty equipment, such as power lines and machinery, also contribute significantly to wildfire ignitions. Each year it is reported that over 15,000 fires in the United States are started by fireworks alone, highlighting the critical need for careful behavior and adherence to safety guidelines.

Here are some of the predominant causes of wildfires in the United States:

  • Lightning strikes, which can easily ignite dry vegetation

  • Human induced activities such as; unattended campfires, discarded cigarettes, burning debris

  • Improper use or negligent use of fireworks

  • Sparks from heavy machinery or equipment, overhead power lines, or arsonists

  • Keep in mind, high winds can push heat and embers in uncontrollable ways and cause a wildfire to rapidly expand

Climate change is another major factor contributing to the increased frequency and severity of wildfires. Longer drought periods and higher temperatures make vegetation more flammable, significantly increasing wildfire risk. Understanding all of these causes is essential for implementing effective wildfire prevention strategies and protecting communities and homeowners in fire-prone areas.

Let’s Begin with Creating Defensible Space Around a Home

Illustration of Defensible Space Zones around a home.

Creating defensible space around a home is a key strategy in protecting properties from wildfires. Defensible space is essentially the area around a property that does not include combustible vegetation or combustible materials. This involves establishing buffer zones around homes to reduce wildfire risk and safeguard against flames and fire embers. Defensible space is typically divided into different zones, each with specific vegetation management techniques to maximize fire resistance home defense.

Zone 0 extends from 0 to 5 feet around the home and focuses on intense fuel reduction to prevent ember attacks. This is one of the most critical zones of your home and is referred to as the non-combustible zone. If you live in a mountain community or wildfire prone area, do not include combustible items in this zone. Ideally this zone includes fire resistant materials that will resist fire, not promote it. Non-combustible materials to consider choosing for this zone include concrete, brick, stone, steel and bare ground.

Zone 1 extends up to 30 feet from structures, this zone requires the clearing of dead plants and flammable items.

Items you should consider removing from these zones are combustible items that can easily ignite and turn into fuel for a fire, including:

  • Patio furniture (including furniture cushions, door mats, wicker furniture)

  • Firewood

  • Plants

  • Mulch

  • Tall grass

  • Overhanging trees

  • Combustible decking / fencing

Zone 2 stretches from 30 to 100 feet, where the spacing of shrubs and trees is crucial to minimize fire spread.

Strategic placement of fire-resistant plants and proper maintenance of this zone can greatly improve a property’s resilience to wildfires. Consistent maintenance of these zones is important.

Understand Wildland Urban Interface (WUI) Zones and Fire Resistance Ratings

Wildland Urban Interface is defined as the area where houses are in or near wildland vegetation, and this is the area where wildfires pose the greatest risk to people due to the proximity of flammable vegetation. The Wildland-Urban Interface Zone (WUI) is where homes or properties are near flammable vegetation thus creating a very elevated risk for people and properties within that zone. The objective of WUI is to protect citizens and properties from fire.

Building codes have been established to protect homes within Wildland Urban Interface areas from firestorms. Establishments such as Wildland Urban Interface help keep citizens aware and informed of the protection that can be taken to ensure proper fire safety.

Fire resistance ratings for building materials and roofing materials have been established for building codes. A fire resistance rating is an indicator of a products ability to resist fire. There are the three fire resistance ratings: Class A, Class B, and Class C rated.

  • Class A - severe fire test exposure - able to withstand severe fire exposure

  • Class B - moderate fire test exposure - able to withstand moderate fire exposure

  • Class C - light fire test exposure - able to withstand light fire exposure

For example, CeDUR manufactures a stand alone Class A fire resistant synthetic roofing product. This roofing product is specifically designed and engineered to be look just like wood shakes, but unlike wood shakes that are combustible, CeDUR is completely fire resistant. For homeowners living in mountain communities, WUI zones, or high risk fire zones, CeDUR is a a great roofing type to consider.

Now Let’s Understand Basic Forest Management Strategies

Basic forest management strategies are vital for protecting your home from wildfire damage, especially if you live in a mountain community or high risk wildfire zone.

Here are tactics employed by forest managers that you may consider implementing which can help reduce fire risk:

  1. Creating firebreaks, which are areas devoid of vegetation and debris

  2. Choose non-combustible landscaping materials

  3. Thinning trees, especially by removing dead or diseased ones, to create space that reduces wildfire susceptibility

  4. Provide proper spacing of trees to prevent the rapid spread of wildfires by allowing more room for growth

  5. Keep large trees and combustible plants that are within 30 feet of a property well maintained and devoid of debris, dry vegetation, and pine needles

  6. Implement defensible space and firebreaks if your home is located in a high risk wildfire zone or mountain community

Prioritizing the planting of trees on your land that are resistant to fire, drought, and decay is essential for maintaining forest health near your home and preventing wildfires from encroaching on your property space. Choosing non-combustible landscaping materials can greatly enhance the safety of a home and defensible spaces. Materials like steel or concrete are good choices, as they do not ignite or contribute to fire growth. Combustible materials like mulch, lumber, pine needles, bark, firewood and wood chips should be avoided. By integrating non-combustible types of materials into your property design, you can create a more wildfire-resistant environment and reduce the risk of fire spread.

Replanting and facilitating natural regeneration are critical components of sustainable forest management that help restore forest areas after disturbances like wildfires. Adopting these basic forest management strategies promote long-term health and resiliency of forests, trees, and plants on your property.

Implement Firebreaks on Your Property

Firebreaks are strips of bare land with no vegetation or debris that are designed to reduce the spread of a wildfire. Firebreaks are an effective fire prevention method for managing wildfires by simply removing flammable and combustible items and creating a barrier or “break” between your home and flammable vegetation. Natural firebreaks, such as bodies of water and damp vegetation, are also effective as they cannot easily catch fire.

Constructed firebreaks, which can be made by clearing vegetation with equipment or using hand tools, can provide additional protection. The width of firebreaks typically ranges from 10 to 60 feet, depending on terrain and wind conditions. Establishing firebreaks around burn piles and properties can significantly enhance protection against wildfires. In addition, removing flammable items from firebreak zones can help prevent wildfires from advancing.

Choose Fire-Resistant Landscaping & Exterior Fire Sprinkler Systems

Fire-resistant landscaping is an effective strategy to mitigate wildfire risk. Incorporating fire-resistant plants into your landscaping can slow fire spread and protect properties. Deciduous trees and shrubs are generally more resistant to fire compared to evergreen varieties. These plants often have characteristics like moist leaves, an open growth structure, and thick bark, which contribute to their fire resistance. Regular maintenance, such as watering and pruning your landscape, is essential to keeping plants healthy and effective. Local nurseries can also provide guidance on selecting the best fire-resistant plants suited for your specific climate. By adopting these practices, you can create a more wildfire-resistant landscape around your home.

Exterior fire sprinkler systems can be wildly important in the event of a wildfire. Exterior sprinkler systems provide protection by actively wetting an area, creating a moist barrier that can help prevent the spread of flames by protecting against wind blown embers and radiant heat. This can help mitigate the risk of ignition as a fire approaches by keeping grass and nearby vegetation wet. Exterior fire sprinkler systems are typically mounted on the roof and under the roof’s eaves. While these systems are not common, they are effective and highly recommended for homeowners living in or near wildfire danger zones.

While there is no way to ensure your yard and your home are completely fireproof, you can take precautionary steps to increase the fire resistance of your landscaping. By removing combustible materials like firewood, patio furniture and fire prone vegetation, you can decrease a homes wildfire risk. Replace combustible items with fire resistant materials like stone patios, non-combustible decking, metal or steel patio furniture and fire resistant plants or fire resistant shrubbery. Any plants or tree branches within 10 feet of your home or 15 feet from your chimney should be removed or pruned.

Your Roof is Your First Line of Defense Against Wildfires

In the event of a wildfire, roofs are the most vulnerable part of a home because they present a large expanse where burning debris and embers may land. Flames spread from roof to roof, with embers from the fire being a major cause of traveling fire damage. Sparks and ignited debris can be lifted and carried by convection currents up to a half-mile from a fire.

Fire-resistant roofing materials are a critical component of making homes more resilient to wildfires, especially when considering their fire ratings and roof covering fire rating.

Materials that offer excellent fire resistance include:

  • Synthetic roofs

  • Metal roofs

  • Clay tiles

  • Slate shingles

These materials offer extreme fire resistance and can significantly slow down the spread of flames in the event of a wildfire. This allows more time for first responders to act and make a crucial difference in protecting properties and homeowners from severe fire exposure.

Metal roofing, for instance, is non-combustible, lightweight, and low maintenance, with a lifespan of 40 to 70 years. Similarly, synthetic roofing materials, which can mimic the appearance of wood and natural tiles, provide excellent fire resistance and often come with long warranties. These materials are classified into different classes based on their fire resistance, with Class A fire resistance being the most resistant to fire.

Clay tiles, while highly fire-resistant, need appropriate installation to prevent ember penetration, which can compromise their effectiveness. Slate roofing while expensive is another great option for fire-prone areas, given its non-combustible and non-absorbent characteristics.

Selecting the right fire resistant roofing material type and ensuring they are properly installed can significantly enhance your roof’s fire resistance. To learn more about this topic feel free to read our article about the best fire resistant roofing types for your home and their benefits.

To Protect Your Property From Wildfire Damage Don’t Overlook Regular Home Maintenance & Fire Resistant Home Vents

Consistent home maintenance is crucial for home fire safety and creating a wildfire-resistant home. Trimming and clearing debris from around your property helps keep fire risks low. Routine inspections of roofs and gutters can identify issues early and prevent extensive damage or fire hazards. Keeping gutters and downspouts well-maintained and clean from debris and dried leaves is essential to prevent potential fire ignitions from ember attacks. Clogged gutters can act as pathways for fire spread if they contain flammable debris such as leaves and pine needles. Regularly removing debris from gutters and installing gutter guards can prevent the accumulation of combustible materials, significantly reducing fire hazards. These maintenance practices are crucial for maintaining a wildfire-resistant home.

Installing fire resistant home vents provides an added layer of protection against wildfires and potential fire damage. Fire resistant ember proof vents are specifically built to withstand high temperatures and prevent embers from entering a homes attic. They can also allow heat and smoke to escape, helping prevent flames from entering the inside of a home. Certain fire resistant vents also include features like anti clogging and overlapping baffles that trap embers and prevent spread.

Along with creating defensible space around your home, regularly cleaning gutters, removing debris, and installing fire-resistant vents can significantly reduce the risk of a wildfire damaging or destroying your home. Installing fire resistant vents and exterior fire sprinklers can help block embers and suppress flames, reducing wildfire risk while giving your home a fighting chance in the event of a fire. They may also help maintain property value and depending on your insurance provider, may potentially lower insurance premiums by demonstrating proactive fire mitigation efforts.

Have an Emergency Response Plan for Your Family

Having an effective emergency response fire plan is critical for dealing with wildfire emergencies, especially for families living in wildfire danger zones. This plan should include a detailed inventory of emergency resources and equipment readiness. Establishing a clear communication strategy is vital for ensuring timely updates during emergencies, helping to coordinate responses and evacuations. Regular training and drills for your family are essential to keeping everyone familiar with procedures and responsibilities.

Designating assembly points outside of your home or building ensures that all residents can be accounted for after an evacuation. The Community Wildfire Defense Grant program offers funding to help communities create effective wildfire protection plans, further enhancing emergency preparedness.

By having a well-thought-out emergency response plan, families and communities can react more efficiently and effectively during wildfire events.

Be Aware of Community Preparedness and Education

Community preparedness and education are crucial in the fight against wildfires, especially for homeowners living in wildfire prone states like California, Oregon, Montana, Texas, Arizona, Colorado, New Mexico and Oklahoma.

The Ready, Set, Go! initiative equips fire departments with resources to engage residents in understanding and reducing wildfire risks. These programs foster collaboration and knowledge sharing, enhancing community resilience against wildfires.

Regular updates to fire safety laws and regulations are also essential for keeping communities prepared for wildfire risks. Being informed about local fire regulations and weather alerts, like Red Flag Warnings, enables residents to take immediate action during critical fire conditions. Consulting fire safety experts can lead to the adoption of more sustainable fire safety practices and equipment. Storing toxic or hazardous chemicals away from fire-prone areas is crucial to prevent environmental harm in the event of a wildfire or home fire.

Participating in community programs and staying informed can significantly reduce wildfire risks and enhance overall safety.

Consider Fire Resistant Building Materials & CeDUR Shakes

Fire-resistant building materials, highlighting their importance in wildfire-prone areas.

Fire-resistant building materials play a crucial role in enhancing structural fire protection. Cold-formed steel (CFS) is a non-combustible material that does not ignite or contribute to fire growth, making it a preferred choice for fire safety in buildings. Steel-framed structures can withstand fires for up to four hours, limiting the spread of flames and maintaining structural integrity. Buildings constructed with CFS can achieve larger areas and heights due to reduced fire risks compared to structures made with combustible materials.

Concrete and brick is another excellent fire-resistant material due to its non-combustible nature and low thermal conductivity. Insulating Concrete Forms (ICFs) can withstand temperatures up to 2000°F for extended periods, providing significant fire resistance. Brick structures also offer up to 4 hours of fire resistance, significantly slowing fire spread.

Other materials like gypsum boards, which have a non-combustible core that releases steam to slow heat transmission during a fire, and fire-resistant windows made from dual-paned or tempered glass, further enhance the fire resistance of buildings.

Incorporating fire-resistant materials into building designs can greatly improve the safety and durability of structures in fire-prone areas.
