What Is a Wildfire Risk Assessment?
It's an insurer's check of how likely your property is to burn, based on vegetation, terrain, and building materials.
Free to compare
If your letter mentions wildfire risk, the insurer likely ran your address through a modeling tool that scores things like how close trees and brush sit to your house, the slope of the land, and what the roof and siding are made of. A high score can trigger non-renewal even if you've never filed a wildfire claim. Clearing brush, replacing a wood roof, or adding defensible space around the structure can lower that score, and some insurers will reconsider if you make those changes and can show proof.
A score from one insurer isn't a score everywhere
The model that flagged your house weighs things differently than the next insurer's model. Some weigh roof material more, others weigh distance to vegetation more. Comparing lets you find one that scores your property better.
What can you do before the next renewal comes up
Ask the insurer, or the agent who wrote the policy, what specifically drove the score. Some will tell you the distance to vegetation, the slope rating, or the roof material that counted against you. Others won't give specifics, but the non-renewal letter or a follow-up call is worth trying before you assume the cause. Knowing the actual driver matters because fixing the wrong thing won't move the score.
Defensible space is the work most often rewarded. That means clearing brush and dead vegetation for a set distance around the house, limbing up trees away from the roofline, and keeping anything flammable away from exterior walls. Many states and fire departments publish a defensible space standard, often 30 feet close to the house and 100 feet further out where the lot allows it. Meeting that standard and keeping dated photos or a contractor's receipt gives you something concrete to show an insurer, rather than just telling them the yard looks different now.
Roof material carries weight in most wildfire models. A wood shake or shingle roof scores worse than composition, metal, or tile, and replacing it is expensive. It's also one of the few changes that moves the score on its own regardless of what's around the property. Siding matters less than roof and vegetation in most models, though some insurers also look at it, along with things like enclosed eaves and ember-resistant vents.
None of this guarantees the same insurer reverses course. Some will reconsider with proof of the work. Others have pulled back from an entire zip code or county regardless of what any single property has done, and that decision has nothing to do with what the property itself can control. That's why comparing other insurers matters as much as doing the mitigation work. A property that scores poorly in one model may score fine in another, especially once the defensible space and roof are documented and ready to show.
What a wildfire assessment looks at beyond your own lot
The model behind your score doesn't stop at your property line. It factors in the surrounding area, things like how dense the vegetation is for a mile or more around you, how steep the terrain is nearby, whether there's a single road in and out, and how far the nearest fire station or hydrant sits. Two houses with identical roofs and identical cleared yards can get different scores just because one sits at the edge of a canyon and the other doesn't.
Mitigation work sometimes isn't enough to change an insurer's decision, and that's not a reflection of anything you did wrong. If the model weighs regional fire history or fuel load heavily, your individual changes get outweighed by factors tied to the area itself. Ask the insurer whether the non-renewal was driven by your property specifically or by a broader area decision. The answer changes what's worth doing next. If it's your property, mitigation and documentation can help. If it's the area, your time is better spent comparing insurers who still write in that zip code.
Some states have started requiring insurers to give credit for mitigation work. Some also require advance notice before an insurer can pull out of wildfire-prone areas at scale. Whether either applies to you depends on your state, and the rules vary enough that it's worth checking with your state's department of insurance rather than assuming. A local independent agent who places policies with several insurers will also usually know which companies are still active in high-risk parts of your area and which have pulled back.
Keep records of anything related to wildfire risk at your property, not just for the insurer that dropped you. Photos of cleared defensible space, receipts for roof work, and any wildfire risk report the insurer shared with you are worth having on hand when you apply elsewhere. A new insurer running the same address through a different model may ask for the same proof. Having it ready shortens that process considerably.
Before you apply again
Pull together photos of your cleared yard, any roofing receipts, and the risk report if the insurer sent one. Having that ready saves time with the next insurer and shows exactly what's changed at your address.
