How Wildfire Reaches a Home
You don't need to become a fire scientist. You just need to understand that during a wildfire, most home ignitions come from three kinds of exposure.
Embers
Wind-blown embers can travel ahead of a wildfire and collect on or around a structure — roofs, gutters, vents, decks, and combustible materials near the home.
Direct Flame
Nearby vegetation, combustible materials, fences, decks, or other fuels can expose a home to direct flames.
Radiant Heat
Intense heat from nearby burning vegetation or structures can threaten vulnerable building components even without direct flame contact.
Resilience Starts at Home
Wildfire can interact with different parts of your home and property. Looking at those areas one by one makes improvement feel much more manageable.
The home itself
The building is where embers most often find a place to ignite. Roofing, vents, gutters, and the base of exterior walls all matter.
A Class A fire-rated roof kept clear of debris. Flame- and ember-resistant vents, or 1/8-inch or finer corrosion-resistant metal mesh.
The immediate perimeter
The first five feet around your home and attached decks is the most important noncombustible buffer. This is where embers settle and where small fuels can carry fire to the structure.
Replace combustible mulch and plants with hardscape. Move firewood and stored items well away from the home.
Defensible space
This is the area where you manage vegetation to slow fire spread. Specific spacing depends on your slope, vegetation type, and site conditions.
Remove dead vegetation and keep grass mowed. Create spacing between shrubs and prune low tree limbs.
Broader property conditions
Conditions farther from the home can still influence exposure and emergency access. Appropriate treatment varies by property, vegetation, terrain, and local requirements.
Thin vegetation to reduce fire intensity. Keep driveways clear for emergency access.
Appropriate treatment varies by slope, vegetation, terrain, property conditions, and local requirements. Your personalized roadmap focuses on the actions most relevant to your property.
Small Changes, Big Difference
Progress doesn't have to begin with a major construction project. Some meaningful improvements can start with ordinary property maintenance and relatively achievable changes — while structural improvements may require more planning and investment.
Roof, gutters, and accumulated debris from around the home.
Stored items, firewood, and other combustible materials away from the home where appropriate.
Vegetation and property conditions over time.
You don't have to solve everything at once.
Your personalized roadmap helps you focus on practical improvements for your property and what to work on next.
Understanding Your BURNGRADE
Your BurnGrade is a number that helps you understand the wildfire-resilience conditions of your property and track improvement over time.
Where your property stands today.
A practical near-term target based on selected improvements.
Every property is different. Your assessment identifies conditions around your home, and your personalized roadmap organizes practical improvements into a path you can work through over time. Your BurnGrade gives you a starting point — your roadmap helps turn what you learn into practical next steps.
Your 4-Week Goal is based on selected improvements to your property. It is a coaching target, not a prediction or guarantee.
BurnGrade does not predict wildfire loss or insurance risk. It helps measure property-level wildfire resilience conditions and improvement progress.
Maintain Your Progress
Wildfire resilience is ongoing upkeep, not a one-time project. Vegetation grows back, gutters refill, and debris accumulates. A seasonal rhythm helps keep your property resilient.
Spring
Re-assess and clear winter debris.
Re-run your BURNGRADE assessment; remove dead vegetation and fallen branches.
Pre-Fire Season
Prepare the immediate perimeter.
Clear gutters and roof valleys; move firewood and combustibles away from the home.
Fall
Reduce accumulated fuels.
Remove leaf and pine-needle litter; clear brush and under-deck areas.
Winter / Off-Season
Plan structural improvements.
Schedule major hardening projects — roofing, siding, or ember-resistant vents.
Re-run your BURNGRADE assessment each spring and after any major change — a new roof, a cleared lot, or a neighbor's project can all shift your vulnerabilities.
