Treat the home as a connected system
A new roof is valuable information, but it does not describe the entire building. Vents, wall details, attached decks, windows, and the space immediately beside the structure can each change its exposure. IBHS research emphasizes coordinated measures because one upgraded component cannot fully protect a home with other vulnerable pathways. Hardening is risk reduction, not a fireproofing guarantee.
Start with an assessment suited to the house you own. Its age, design, additions, maintenance, and surrounding conditions matter. Ask the assessor to identify specific observations, explain priorities, and distinguish repairs from upgrades. If an insurer has already provided inspection findings, bring those documents so the conversation addresses the actual concern rather than a generic improvement list.
Review the roof and openings
Roof condition and the complete assembly
Ask a qualified roofer to identify the roof covering, condition, and applicable fire classification of the installed assembly. A material name alone may not establish how the complete roof performs. Record the installation date and keep product information. Include roof edges, accumulated debris, and repair needs in the inspection. Avoid climbing onto the roof to gather insurance photographs.
A Class A fire-rated roof is a central component of IBHS wildfire guidance. When replacement is already necessary, ask contractors to explain assembly requirements, flashing, permits, ventilation, and maintenance together. Request comparable proposals so a lower bid does not silently omit work needed for the specified installation. Follow local code and the manufacturer's instructions.
Vents and other entry points
IBHS identifies windblown embers as a major ignition concern and studies how vents admit them. Ask about tested ember-resistant vent products appropriate for your building. A qualified installer should preserve necessary airflow and follow the relevant code and product instructions. Do not seal ventilation openings or attach improvised materials that create moisture, combustion, or equipment problems.
Have the assessment address visible gaps at roof edges, wall connections, and doors where relevant. Give contractors permission to explain what they cannot verify without further inspection. An accurate “unknown” is preferable to a confident claim based on a distant photograph. Record any follow-up needed before representing a feature as upgraded in an insurance application.
Include walls, windows, decks, and attachments
Ask the assessor to review wall materials and their condition, windows, exterior doors, and the junctions between building components. If you plan a renovation, discuss wildfire performance before ordering materials. Product labels, installation details, and site conditions all deserve attention. A general claim that a product is “fire resistant” should not replace the documentation for the specific product.
Attached decks, stairs, and fences belong in the same review because they connect outdoor conditions to the house. Consider what is stored beneath and beside them, how debris collects, and whether nearby improvements change the exposure. Detached garages, sheds, and other buildings also deserve assessment. Document each structure separately so insurance descriptions do not become ambiguous.
Use the defensible space guide alongside this building review. Landscaping work and construction work often involve different contractors, budgets, and schedules. Coordinating those plans helps avoid paying for a finish that must later be removed to complete another project. Ask who is responsible for cleanup and how the finished condition will be documented.

Write a useful scope before buying
For each proposed project, identify the observed problem, the proposed solution, the person responsible, and the expected completion date. Ask whether a permit, structural review, association approval, or specialist is needed. Keep optional cosmetic work separate from the resilience scope. This makes it easier to compare bids and decide what you can reasonably complete now.
| Project question | Record to request |
|---|---|
| What exactly will be installed? | Product identification and relevant installation specifications. |
| Who will perform the work? | Contractor details and any credentials required locally for that work. |
| What happens at completion? | Invoice, photographs, permit signoff where required, and maintenance instructions. |
| Will an insurer recognize it? | The insurer's documentation rules and any written underwriting response. |
Get independent clarification if a sales proposal promises that a retrofit will guarantee insurance or prevent every wildfire loss. Contractors can describe their products and work, but only an insurer can decide what it will offer. For extensive projects, consider a separate professional review of the scope before signing a contract or paying a large deposit.
At project completion, compare the installed work with the written scope. Ask the contractor to identify any substitutions or unfinished items before you describe the project to an insurer. Keep warranties and care instructions where the next owner or property manager can find them.
Prioritize without assuming a financial return
Not every household can undertake a major renovation. Ask which maintenance tasks are urgent, which upgrades can align with ordinary replacement cycles, and which combinations are most useful for the property. Avoid universal cost estimates: roof size, access, labor, materials, and local requirements can change the budget substantially. Obtain property-specific pricing and allow for identified uncertainties.
Ask local agencies about assistance programs, but verify current eligibility and funding directly. A program described in an older article may be unavailable or limited to certain properties. Do not hire a contractor assuming reimbursement is automatic. If you need a phased plan, describe that constraint early and seek written priorities that distinguish completed, scheduled, and deferred work.
Use the record in an insurance review
Before an expensive project intended partly to support insurance eligibility, ask the agent what documentation the prospective insurer accepts. Some situations may require an assessment or a particular product standard. Clarify whether the work could affect eligibility, price, inspection conditions, or none of those. A useful safety improvement does not necessarily produce an insurance credit.
Build a property file with dated photographs, invoices, product descriptions, roof records, and any inspection result. Include the work actually completed and explain remaining concerns honestly. Keep it concise enough that an underwriter can find each item quickly. Use a secure channel if a licensed professional requests identifying or policy information.
If you face nonrenewal, ask whether documented corrections allow reconsideration while seeking other coverage options. Do not assume a planned project extends existing coverage. Confirm effective dates and any outstanding conditions in writing. Continue reviewing your evacuation arrangements, because a hardened home never removes the need to leave when authorities direct you.
Common questions
What is the difference between home hardening and defensible space?
Home hardening concerns building components and their vulnerabilities. Defensible space concerns conditions around the structure. The two approaches work together and should be considered in one property plan.
Does a metal roof automatically make my house wildfire resistant?
No. The installed roof assembly, condition, detailing, and the rest of the building matter. Ask a qualified roofer to identify the applicable fire classification and any repair or installation concerns.
Can I block attic vents to keep embers out?
Do not improvise a permanent closure of required ventilation. Ask a qualified professional about tested ember-resistant vents compatible with your building, local code, and manufacturer requirements.
Should I replace all of my windows immediately?
A property assessment can help prioritize window work against other vulnerabilities and your budget. Do not assume a universal replacement schedule or guaranteed insurance benefit applies to every home.
What should I request from a contractor?
Request a written scope, product information, project schedule, permit responsibilities, completion records, and maintenance instructions. Verify locally required credentials before authorizing specialized work.
Will an insurer accept my upgrade photos?
Ask the insurer or its authorized representative. Some reviews may accept photos, while others need additional documents or an inspection. Do not buy a certificate before confirming whether it is relevant.
Is home hardening worth documenting if no discount is available?
Yes. Accurate records explain the condition of the property and support future review. Their usefulness does not depend on a promised premium reduction.
Does completing the work let me stay during an evacuation?
No. Follow emergency instructions and evacuation orders. Hardening cannot guarantee a home will survive or make conditions safe for occupants.
