Wildfire Insurance Non-Renewal in the Boise Foothills
If you’ve had a non-renewal notice, a large premium increase, or a letter mentioning “roof condition,” you’re not being singled out. It’s happening across wildfire-exposed Idaho, and the foothills are the epicentre locally.
Key takeaways
A 2023 U.S. Senate Budget Committee study ranked Boise County 87th in the nation for highest homeowners insurance non-renewal rate
Foothills residents report calling twenty-plus carriers and finding one willing to quote, often at double the prior premium
Idaho Insurance Commissioner Dean Cameron ordered a data call to gather Idaho-specific figures
A proposed wildfire risk-reduction grant fund had not passed the Legislature as of early 2026
Research consensus: a Class A fire-rated roof is the single most impactful upgrade for wildfire insurability
What’s actually happening
Carriers are repricing wildfire risk across the western United States, and Idaho is caught in it. In practice that shows up three ways:
Non-renewal. Your policy isn’t cancelled mid-term — it simply isn’t offered again at renewal.
Re-rating. You’re offered renewal at a substantially higher premium.
Conditional renewal. You’re offered renewal subject to changes — often roof-related.
The foothills carry it hardest because of proximity to undeveloped wildland, terrain that complicates firefighting access, and property values that make individual losses large.
Where Idaho’s regulation stands
Idaho Insurance Commissioner Dean Cameron ordered a data call requiring carriers to submit Idaho-specific figures on premiums and non-renewals — the state was otherwise working from national data that may not reflect local conditions.
Cameron also proposed a wildfire risk-reduction grant fund to help homeowners pay for mitigation work. As of early 2026 the Idaho Legislature had not passed it.
So the policy response is in progress and incomplete. In the meantime the practical burden sits with homeowners.
Why your roof is the pivot point
In a wildfire, most homes are not lost to a wall of advancing flame. They’re lost to wind-driven embers landing on the structure and finding somewhere to lodge and ignite.
The roof is the largest horizontal surface on your house and the primary ember-catching surface. Valleys, gutters, and the areas around penetrations collect debris, and debris catches embers.
That’s why the research consensus is consistent: a Class A fire-rated roof is the single highest-leverage upgrade for wildfire insurability. It’s the biggest surface, and it’s the one with a clear, documentable standard.
What counts as Class A
Class A is the highest fire rating for roof coverings and assemblies. In the Boise foothills it isn’t optional — under Fire Prevention Code section 4908, roofs in the WUI overlay must have a Class A roof covering or Class A roof assembly, and the requirement extends to repairs.
Important distinction: Class A is an assembly rating, not just a shingle rating. A Class A shingle installed outside its listed assembly isn’t a Class A roof — and if your insurer asks for documentation, that’s what they’ll want to see.
What to do if you’ve had a notice
Read the notice carefully. Non-renewal, cancellation and conditional renewal are different things with different timelines and different options.
Find out what your roof actually is. Class A or not, and whether you have the documentation. If you don’t know, get an inspection — it’s the first question any new carrier will ask.
Ask what would change the answer. Sometimes it’s the roof. Sometimes it’s defensible space, vents, or decking. Ask specifically what mitigation the carrier would recognise.
Check your declarations page for ACV, RCV, or a Roof Payment Schedule endorsement before you shop — the terms matter as much as the premium. See [ACV vs RCV].
Document mitigation work. Keep invoices, photos and manufacturer documentation. Undocumented mitigation is hard to get credit for.
Start early. Non-renewal notices come with a deadline, and a foothills homeowner calling twenty carriers needs weeks, not days.
Beyond the roof
Defensible space is the other half. New structures in WUI Zones A and B require 30 feet of defensible space from undeveloped land. Ember-resistant vents, non-combustible siding and clear gutters all contribute.
Avimor, the roughly 35-square-mile development in the Boise foothills, is a recognised Firewise USA community where structures use cementitious siding and Class A roofs. It’s a useful reference for what a fully mitigated foothills property looks like.
Idaho Firewise and the National Interagency Fire Center — headquartered in Boise — both publish homeowner mitigation guidance.
FAQs
Can my insurer drop me because of my roof?
They can decline to renew. Non-renewal is different from mid-term cancellation and comes with notice requirements.
Will a new roof get my insurance back?
It’s the highest-leverage single change, but it isn’t a guarantee — carriers weigh location, defensible space and construction alongside the roof.
How do I prove my roof is Class A?
Manufacturer documentation for the assembly plus installation detail. Keep it filed.
Is metal better than asphalt for wildfire?
Both can achieve Class A. Metal has advantages on foothills properties for snow shedding and wind exposure. It costs more up front and lasts longer.
Has Idaho done anything about this?
Commissioner Cameron ordered a data call and proposed a wildfire mitigation grant fund, which had not passed the Legislature as of early 2026.
