We adhere to Class A assembly: the covering, underlayment and deck installed exactly as the tested, listed system, in asphalt, metal, stone-coated steel, and synthetic systems suited to mountain architecture.
Jefferson County's Wildfire Resiliency Code (effective July 1, 2026) sets roof rules for homes in its wildland-urban interface. We check your parcel on the county WUI map and build and document the roof to meet it.
Noncombustible roofing that pairs wildfire resilience with snow and hail performance. Compared in detail on our Roofing Materials page.
Vents listed to the ember-resistance standard (ASTM E2886) or screened with 1/8-inch noncombustible mesh at ridges, soffits, and gables: the entry points embers actually find.
Metal gutters and guards that keep needle litter from accumulating where embers land.
Enclosed, noncombustible eave and soffit details that deny embers a foothold at the roof edge.
Flashing and material choices at dormers and wall intersections, where debris collects and fire finds fuel.
Guidance on glazing and exterior-door choices as part of a whole-home hardening plan.
The junctions where decks and siding meet the structure: detailed and documented as part of the hardening assessment.
Wildfire resilience increasingly affects insurability in the foothills. Class A assemblies, ember-resistant venting, and fire-wise material choices are factors carriers weigh, and documented hardening work belongs in your insurance file. We document what we build so you can share it with your carrier and agent.
How claims work →On parcels in the county's WUI Overlay District, the Jefferson County Wildfire Resiliency Code (effective July 1, 2026) requires a roof assembly classified as Class A under ASTM E108 / UL 790, plus noncombustible gutters, ember-resistant vents, metal-lined open valleys and fire-resistant skylights. It applies to new homes and to reroofs affecting 25% or more of the roof. Whether your home is on the map depends on the parcel; we look it up as part of your assessment.
A fire rating is earned by a tested system: the covering, the deck and often a specific underlayment. Some products are Class A on their own; others reach Class A only over the underlayment they were tested with. Jefferson County's WUI code requires the assembly to be Class A, so we install every system exactly as it was listed.
It's the largest surface embers land on, and the roof assembly is one of the most-studied factors in whether a home survives an ember storm. A Class A assembly with ember-resistant venting addresses the most common ignition paths at the roofline.
Standing-seam metal and stone-coated steel are noncombustible, and many asphalt and synthetic systems achieve a Class A assembly rating. We'll walk the options against your home, HOA, and budget.
Often, yes: vent upgrades, gutter protection, and eave details can be retrofitted. A CHGR Roof Assessment Report™ is the right starting point: it documents what you have and what would improve it.
