The Marshall Fire — December 30, 2021

The Largest Suburban Wildfire in Colorado History

In a single afternoon, the Marshall Fire destroyed 1,084 homes across the southeast corner of Boulder County — roughly 800 inside the Town of Superior (Rock Creek, Sagamore, Saddle Brook, Heatherwood, Original Superior), around 500 inside the City of Louisville (Centennial Valley, Hillsborough, the Enclave, Coal Creek Ranch), and additional losses across unincorporated Boulder County between the two towns. It remains the most destructive wildfire in Colorado history and the largest suburban-area wildland fire the state has ever seen.

Four years later, the rebuild is still active. A meaningful pipeline of ground-up reconstructions is still in permit or framing, a second wave of insurance supplements — for code upgrades and assembly-upgrade gaps that didn't surface until tear-off — is still being written, and the insurance market itself has been reshaped by roughly two years of carrier coverage disruption. We built our Marshall Fire rebuild practice around that reality.

WUI Assembly — Post-Marshall Code

What a Class A Fire-Rated Rebuild Roof Actually Requires

A Class A rating isn't a shingle — it's a documented assembly. Post-Marshall code in Superior, Louisville, and Boulder County requires each of the following specified as a system, certified together, and documented in the permit packet.

Class A Roof Assembly

UL 790 / ASTM E108

A full-system fire-rating — covering, underlayment, deck, and detailing tested together for flame penetration, flame spread, and resistance to flying brands.

  • Class A-certified covering (shingle or metal)
  • Class A-listed synthetic underlayment
  • Non-combustible drip edge & edge metal
  • Assembly certificate filed with permit

Ember-Resistant Vents

ASTM E2886 / 1/8" Mesh

Ember intrusion — not direct flame — was the primary failure mode on December 30. Baffled, flame-blocking vents are now required on all attic, crawlspace, and roof-line intakes.

  • Brandguard flame-blocking vents
  • Vulcan ember-resistant intake / ridge
  • O'Hagin low-profile ember vents
  • Product listings filed at final inspection

Non-Combustible Gutters & Edge

Where Code Requires

Several post-Marshall WUI zones require non-combustible gutters and edge metal on fire-facing exposures — embers accumulate in debris-filled aluminum gutters and ignite the fascia.

  • Steel or aluminum gutters with ember guard
  • Non-combustible fascia & drip edge
  • Leaf-screen for ember defensibility
  • Downspout termination per code

Ignition-Resistant Soffits

Non-Combustible on Fire Exposure

Exposed rafter tails and combustible soffits were a common ignition point in the Marshall footprint. WUI code now requires ignition-resistant or non-combustible soffit material on exposures designated in the code.

  • Fiber-cement or metal soffit panels
  • Sealed eave construction, no open gaps
  • Enclosed rafter tails where required
  • Matches the Class A assembly detailing

Class A Shingle Brands

Specified by Default

Three asphalt brands we specify by default for the Class A + Class 4 impact stack on Marshall Fire rebuilds — each listed as a full Class A assembly with the matching underlayment.

  • Malarkey Windsor (SBS polymer-modified)
  • GAF Timberline Armor Shield II
  • CertainTeed Landmark Pro
  • All UL 2218 Class 4 impact rated

Metal — Class A by Default

Standing Seam & Stone-Coated Steel

Metal roofing is effectively a Class A assembly without needing an upgraded underlayment — and it's becoming a more common rebuild spec where owners want the highest fire performance and a longer service life than asphalt.

  • Standing-seam steel & aluminum
  • Stone-coated steel (shingle profile)
  • Hidden-fastener systems for wind uplift
  • 40-50+ year service life

Insurance Market After Marshall

The Carrier Landscape in Boulder County Today

The Marshall Fire reshaped the Colorado homeowner's insurance market. Roughly two years of coverage disruption followed — some carriers pulled back, others (with California wildfire experience) stepped up for high-value rebuilds. Documentation is the common thread.

Still Writing — Rebuild & High-Value

Active in Boulder County WUI Zones

Carriers that have been consistent writers through the rebuild years. Most require a documented Class A assembly, ember-resistant vent listings, and defensible space confirmation at underwriting or renewal.

  • Travelers
  • Chubb
  • AIG Private Client
  • USAA (military/veteran)
  • Cincinnati
  • PURE
  • California-experienced specialty carriers

Reduced New Business or Tightened Underwriting

Restrictions Since the Marshall Fire

Carriers that pulled back in Boulder County's WUI zones — reduced new writing, tighter wildfire-zone underwriting, or non-renewals. Existing policies may still renew with a documented WUI-compliant assembly and defensible space.

  • State Farm (reduced new writing)
  • Allstate (tightened underwriting)
  • Select regional carriers
  • Carriers with no California wildfire experience

FAQ

Common Questions From Marshall Fire Rebuild Homeowners

On December 30, 2021, the Marshall Fire tore through the grasslands and subdivisions north of US-36 and became the most destructive wildfire in Colorado history — and the largest suburban-area wildland fire the state has ever seen. In a single afternoon, 1,084 homes were destroyed: roughly 800 inside the Town of Superior (Rock Creek, Sagamore, Saddle Brook, Heatherwood, Original Superior), around 500 inside the City of Louisville (Centennial Valley, Hillsborough, the Enclave, Coal Creek Ranch), and additional losses across unincorporated Boulder County between the two towns. More than four years later the rebuild is still active: a meaningful pipeline of ground-up reconstructions is still in permit or framing, and a second wave of insurance supplements — for code upgrades and assembly-upgrade gaps that didn't surface until tear-off — is still being written. We built our Marshall Fire rebuild practice around that reality and staffed a dedicated crew inside the burn footprint.
A Class A fire-rated roof assembly is the highest classification under UL 790 / ASTM E108 — a full system (covering, underlayment, deck, and detailing) tested and certified to resist severe fire exposure: no flame penetration through the deck, limited flame spread across the surface, and resistance to flying brands. Before the Marshall Fire, most of the suburbs along US-36 defaulted to Class B or the minimum code requirement with limited WUI (wildland-urban interface) enforcement. After December 30, 2021, Superior, Louisville, and Boulder County all amended their codes to require a full Class A assembly on rebuilds and new construction in the burn footprint and designated WUI zones. The critical nuance is 'assembly' — a Class A-rated shingle over a standard underlayment does not make a Class A roof. The whole system has to be rated together: Class A covering, Class A-listed synthetic underlayment, non-combustible drip edge, and detailed flashing. We specify and document the full assembly so the certificate goes straight into your permit file and insurance packet.
All three jurisdictions tightened their WUI codes after the Marshall Fire, but each moved at its own pace with its own amendments. The Town of Superior adopted some of the strictest post-Marshall updates in Colorado — a town-wide WUI overlay requiring Class A assemblies, ASTM E2886 ember-resistant venting throughout, non-combustible eave construction on fire-facing exposures, and defensible space documentation at permit. The City of Louisville set up a dedicated Marshall Fire rebuild permit track with fee waivers and expedited review, paired with WUI zone updates that require the same Class A assembly plus ignition-resistant soffits and — in some zones — non-combustible gutters. Boulder County unincorporated permits (the parcels between the two towns that still lost homes) go through the county building department under its own WUI worksheet, IECC 2021 energy amendments, and sometimes a separate septic or well update. The jurisdictional line runs right through several burn-impacted neighborhoods, so we pull parcel data before we quote to make sure we're filing the correct packet in the correct office.
Marshall Fire rebuilds are full reconstructions, and the insurance math is fundamentally different from a standard roof claim. A pre-2021 Replacement Cost Value (RCV) policy was typically written against the original, non-WUI-compliant structure — Class B or minimum-code shingle, standard framing, pre-IECC-2021 energy envelope. Rebuilding now means building to the current WUI code: Class A assembly, ember-resistant venting, IECC 2021 insulation and R-value targets, solar-ready framing and conduit, and ignition-resistant exterior detailing. Where the original policy didn't include a code-upgrade (Ordinance or Law) rider — or included one with a low sublimit — there is often a significant gap between the RCV settlement and the as-rebuilt cost. We document the specific code-driven line items in a format carriers and public adjusters recognize: the Class A assembly certificate, the ASTM E2886 vent listings, the R-value upgrade worksheet tied to the IECC amendment, and the solar-ready attestation. Most of the Marshall Fire supplements we still see funded in 2026 pivot on exactly this documentation.
The Marshall Fire meaningfully reshaped the Colorado homeowner's insurance market. Several national carriers pulled back — State Farm reduced new-business writing across Boulder County's WUI zones, Allstate tightened underwriting, and some regional carriers added wildfire-zone exclusions or declined to renew in the burn footprint entirely. At the same time, carriers with California wildfire experience stepped in: Travelers, Chubb, AIG, and USAA (for military and veteran households) have been the most consistent high-value writers through the rebuild years, and a handful of California-experienced specialty carriers have entered the Colorado market behind them. The common thread with the carriers that are still writing is documentation: they want a completed Class A assembly certificate, the ember-resistant vent product listings, the defensible space confirmation, and the Class 4 impact certificate bundled into one packet. We build that packet for every Marshall Fire project and hand it to the homeowner in a form their agent or underwriter can submit directly — a documented fire-ready assembly is often the difference between a renewal and a non-renewal.
Solar panels themselves are not strictly mandatory, but solar-ready construction is — all three jurisdictions (Town of Superior, City of Louisville, and Boulder County unincorporated) amended solar-ready provisions into their rebuild codes. Every new structure in the burn footprint has to include a designated south-facing solar-ready zone with unshaded roof area, reinforced framing, conduit pathways, and reserved electrical panel capacity. Because these rebuilds are clean-sheet new construction from the foundation up, installing solar during the build is dramatically cheaper than retrofitting after move-in — no second tear-up, no retrofit conduit chase. For owners who want solar from day one, we coordinate the Xcel Energy Solar*Rewards interconnection through Xcel's territory (which covers nearly all of the burn footprint) and file the jurisdictional solar permit alongside the building permit. The Tesla Solar Roof has been particularly popular in the Superior and Louisville rebuild markets — it arrives as the roof (integrated glass tiles) rather than as an array bolted to one, which tends to breeze through HOA architectural review in Rock Creek and Centennial Valley where surface-mount solar can face stricter scrutiny.
For a Class A fire-rated assembly on a Marshall Fire rebuild we specify three asphalt brands as our defaults, plus metal as the Class A-by-default alternative. <b>IKO Nordic</b> is our flagship Class 4 spec &mdash; SBS polymer-modified, UL 2218 Class 4 impact, Class A fire-rated assembly, and we are an IKO ROOFPRO Select installer which unlocks the enhanced manufacturer warranty. Malarkey Windsor is also commonly specified &mdash; SBS polymer-modified, Class A fire, UL 2218 Class 4, with NEX Polymer-modified asphalt that handles Colorado's altitude and temperature swings well. CertainTeed Landmark Pro carries the Class A assembly rating, has a strong color palette for HOA architectural review (especially in Rock Creek and Centennial Valley), and pairs cleanly with CertainTeed's DiamondDeck synthetic underlayment for a fully-listed Class A system. Metal roofing &mdash; standing seam and stone-coated steel &mdash; is the Class A default for owners who want the highest fire performance and a longer service life than asphalt. All options meet the post-Marshall WUI code when installed as a documented assembly.
A Marshall Fire rebuild is not a standalone roof — it's one trade inside a ground-up reconstruction that a general contractor is sequencing across framing, sheathing, mechanicals, insulation, windows, siding, solar, and finishes. Our role is to land the roofing scope (and often solar) cleanly inside the GC's schedule without holding up the next trade or the next inspection. In practice that means: coordinating dry-in timing so the house can close and the interior trades can start; specifying the deck, underlayment, and ventilation details during framing review so the structural engineer and the roofer are aligned; handling our own WUI compliance packet and Class A assembly certificate directly with the building department so the GC isn't chasing it; staging material deliveries off the GC's site logistics plan; and documenting everything the insurance supplement will need, whether the homeowner is invoicing the carrier directly or the GC is consolidating the full rebuild cost. We have worked alongside several of the active Superior and Louisville rebuild GCs and have a documented handoff process — shared schedule, shared inspection windows, and a single point of contact on both sides so nothing drops between the roofer and the builder.
