How to prepare your home for a wildfire insurance inspection

Carriers writing homes in the foothills above Boise, the pine country around Flagstaff and Prescott, the canyon neighbourhoods along Utah's Wasatch Front and the Sierra edge of Nevada now score the wildfire exposure of the parcel before they quote, and in the higher-scoring areas they send an inspector before they bind or at the first renewal. The inspector is not there to judge the house; the score for the location is already set by the model. The inspection is about what the owner has done to the structure and the ground around it, which is the only part of the risk the owner controls, and it is scored against a checklist that is remarkably consistent across carriers.

That makes the inspection something you can prepare for. Most of the items on the list are a weekend's work or a modest contractor's invoice, and the difference between a pass and a conditional notice is usually a handful of them. This guide is that list, in the order an inspector walks it, with what to gather, what to document and what to do when the report arrives.

What to gather first

Assemble these before the appointment so the inspector's questions have answers and the file has evidence.

• The inspection notice or the carrier's mitigation checklist, if one was sent; it names the items that will be scored.
• Roof documentation: age, material, and the installer's invoice or the permit, since a Class A roof is the single most valuable item on the list.
• Receipts or photographs for any mitigation already done: vent screens, gutter guards, deck work, tree removal, siding replacement.
• Any assessment from a local fire district, a Firewise community programme or a state forestry agency; inspectors accept them as corroboration and a recognised community programme can carry a discount with some carriers.
• A plan or a rough sketch of the lot showing the house, outbuildings, propane tank, fences, decks and the nearest trees, marked with distances.
• Access details: gate codes, dogs, and whether the driveway is passable by a fire engine, which is itself an item on many checklists.

Step one: the roof, the vents and the gutters

Embers arrive before flames and land on the roof, so the inspector starts there. A roof of asphalt shingle, metal, tile or other Class A rated material scores well; wood shake scores badly enough that some carriers will not write it at any price. The roof also has to be clean: needles and leaves in the valleys and behind chimneys are fuel where embers land. Clear them, and clear the gutters or fit metal gutter guards, since a gutter full of dry debris under the eave is the most common way a house is lost to embers.

Every vent is an opening that lets embers into the attic or the crawl space. The standard is fine metal mesh over each one, or ember-resistant vents made for the purpose; fibreglass screen melts and plastic soffit vents fail. Check the attic vents, the gable vents, the soffit and eave vents, the crawl space vents and the dryer vent. Where the roof meets a wall, the joint should be sealed and free of debris, and skylights should be tempered or double-pane glass. Chimney and stovepipe outlets should have a spark arrestor cap.

Step two: the first five feet

The zone immediately around the foundation is the second focus, and inspectors are strict about it. The goal is nothing that can burn touching or within arm's reach of the house. That means no bark mulch against the walls, no shrubs under the windows, no firewood stacked against the siding, no wooden trellis or plastic lattice, no doormats of coir, and no stored items under the deck. Replace mulch and plantings in this strip with gravel, pavers, bare soil or concrete, and move the firewood well away from the structure and the fence line.

Look at what the house is wearing. Combustible siding meeting the ground, unenclosed eaves, open decks with gaps that collect debris, and wooden fences that run to the house and act as a fuse all lower the score. The fixes range from cheap, cutting a fence back and replacing the last section with metal, to expensive, re-siding in stucco or fibre cement, and the inspector will note them as recommendations rather than conditions unless the exposure is severe. Do the cheap ones before the visit.

Step three: the defensible space beyond

From the five-foot line out to roughly the width of a house lot, the standard is lean, clean and green: trees limbed up so the lowest branches are well above the ground, canopies separated so fire cannot run from one to the next, dead material removed, grass kept short, and nothing growing under trees that would carry fire into the crown. Ladder fuels, meaning shrubs under trees, are what inspectors photograph most. Beyond that zone, and out to the property line where the lot is large, the standard relaxes to thinning and removing dead wood so a fire arriving from the wildland slows and drops to the ground rather than running through the treetops.

Outbuildings, sheds, wood piles, propane tanks and vehicles get the same treatment as the house: cleared ground around them, and enough distance from the house that a fire in one does not become a fire in the other. A propane tank with brush against it is a standard failing item. If the lot borders public land, national forest or an undeveloped slope, the inspector will record that as exposure, but the score for the lot itself still turns on what you have cleared. State forestry agencies in all four states and many fire districts publish defensible space guides that match what carriers expect, and several offer a free assessment visit that produces a report you can hand the inspector.

Step four: document, host the visit and read the report

Photograph everything you did, before and after, with dates, and keep the receipts. The inspector's report is the carrier's evidence; yours is what wins an appeal if the report is wrong or the photographs were taken from an angle that hides the work. On the day, be present or have someone who knows the property present, unlock the gates, and walk the inspector around the mitigation rather than leaving them to find it. Point out the vent screens, the roof material and the cleared zone explicitly. A drive-by inspection that misses the mitigation produces a worse score than a walk-through that sees it.

The report arrives as a pass, a pass with recommendations, or a conditional notice listing required items and a deadline. Recommendations are advice for the next renewal; conditions are not optional, and the policy will be non-renewed or cancelled if they are not completed and confirmed, usually by photographs or a reinspection. If a condition seems wrong, contest it promptly with your own photographs through your agent; carriers correct factual errors and rarely extend deadlines for items that were simply ignored. If the carrier declines the risk outright, the same mitigation file is what gets the next carrier, or a surplus lines market, to write it.

Common mistakes

These recur in conditional notices and declinations across the region.

• Treating the inspection as a formality and doing nothing before the visit.
• Clearing the yard but leaving the gutters, the roof valleys and the vents untouched; the inspector looks up first.
• Keeping bark mulch and foundation shrubs because the landscaping was expensive.
• Stacking the winter's firewood against the house or under the deck.
• Letting the wooden fence run straight to the siding.
• Not being present, so the inspector photographs from the driveway and misses the work behind the house.
• Missing the deadline on a conditional notice and finding the policy cancelled in fire season, when no other carrier is writing the zip code.

A worked example

Suppose a household in the foothills north of Boise receives notice that the carrier will inspect before renewing, and the current premium is $3,200. Over three weekends they clear the roof and gutters and fit metal gutter guards for $400, replace every attic and crawl space vent screen with fine metal mesh for $250, pull the bark mulch and junipers from the foundation strip and lay gravel for $900, move the woodpile and the propane tank's surroundings, and pay an arborist $1,800 to limb up the pines and take out two dead trees near the deck. They photograph everything and hand the inspector a copy of a free assessment the local fire district completed the month before. The report comes back as a pass with one recommendation, to replace the last section of cedar fence at the house with metal. The policy renews at $3,000 with a mitigation credit rather than being non-renewed, and the neighbour who did nothing receives a conditional notice with a deadline in the middle of July. The figures are hypothetical; the checklist items are the real ones.

How to use this

If an inspection notice has arrived, send it to us with photographs of the property and we will tell you which items on it the carrier scores hardest and which are advisory, and help contest anything the report gets wrong. If the carrier has already declined or non-renewed, the same mitigation file goes to the carriers we represent in Arizona, Nevada, Utah and Idaho and to the surplus lines markets that write exposed homes. If the property already passes on every item above, the recommendation is to keep the photographs current at each renewal and change nothing else.
