## Price

$8,700-$34,000 full roof replacement, Class A-rated assembly, installed. RESEARCH.md has no separately-published cost premium for Class A-rated assemblies specifically, so this uses the same reconciled full-replacement range as our general roof replacement page (Emerald City's $8,700-$17,000 asphalt figure and Valentine's $15,600-$34,000 WA-wide composite-shingle figure) since Class A-rated products exist across asphalt shingle, metal, and other material lines already covered by those ranges; metal roofing is Class A-rated by default and may run toward the metal roofing page's higher range instead.

## What's included

- A site check for whether your property actually falls within Issaquah's wildland-urban interface terrain — the requirement doesn't apply everywhere in the city
- Explanation of Washington's Class A fire-rated roof assembly requirement (WAC/RCW 19.27.560) and when it applies: new construction, and existing buildings undergoing 50%+ roof replacement
- Class A-rated material options across asphalt shingle, metal, and other roofing lines — tested and rated to ASTM E108/UL 790, the standard the code references
- Full tear-off to the deck and assembly installation (underlayment, fasteners, ventilation) matched to the specific product's tested Class A rating, since a Class A shingle installed off-spec does not carry the rating in practice
- Fire-treated cedar shake as an option where a wood-look material is wanted alongside Class A compliance
- A written price before any work starts, broken out by material option
- A permit pulled through MyBuildingPermit.com when the job requires one
- Full site cleanup, magnet sweep for dropped fasteners, and haul-away of the old roofing

## Process

01. **Free on-site inspection and WUI check** - We walk the roof and confirm whether your address sits in wildland-urban interface terrain where the Class A requirement applies, based on proximity to Cougar, Squak, or Tiger Mountain's forested slopes.
02. **Material and assembly selection** - We walk you through Class A-rated options across asphalt shingle, metal, and fire-treated cedar shake, and confirm the exact assembly (underlayment, fastening, ventilation) needed to carry the tested rating.
03. **Permit and install** - We confirm permit requirements through MyBuildingPermit.com, then tear off and install the assembly to the manufacturer's tested Class A specification.
04. **Inspection and documentation** - Final inspection and a walkthrough, with documentation of the installed assembly's Class A rating for your records.

## When it's needed

- Property located near Cougar, Squak, or Tiger Mountain's forested slopes
- Planning new construction in Issaquah's wildland-urban interface terrain
- Full roof replacement planned that would trigger the 50%+ code threshold
- Current roof material isn't Class A-rated and you want to confirm whether that's a problem
- HOA or insurer has asked about your roof's fire rating
- Considering cedar shake or another wood-look material and want a fire-rated option

## FAQ

**What is a Class A fire-rated roof, and do I need one near Cougar, Squak, or Tiger Mountain?**

A Class A rating is the highest fire-resistance classification for a roof assembly, tested to ASTM E108/UL 790. Washington requires it for new construction and for existing buildings undergoing 50%+ roof replacement in wildland-urban interface terrain (WAC/RCW 19.27.560) — and much of Issaquah, bordered on three sides by the forested Cougar, Squak, and Tiger Mountain slopes, sits in that terrain. We check your specific address rather than assuming.

**Does a Class A roof cost more than a standard roof?**

It depends on material. Metal roofing is Class A-rated by default at no extra assembly cost. Class A-rated asphalt shingle and fire-treated cedar shake products exist and typically install using the same crew and timeline as a standard reroof — the assembly details (underlayment, fastening pattern) matter more for maintaining the rating than the sticker price of the shingle itself.

**Is my whole roof required to be Class A, or just part of it?**

For a home undergoing 50% or more of its roof replaced, or new construction, the code requirement applies to the roof assembly as a whole, not a partial patch. A smaller repair to an existing non-Class-A roof doesn't automatically trigger the requirement — we'll tell you honestly whether your specific job crosses that threshold.

**Can cedar shake meet a Class A rating?**

Standard untreated cedar shake does not meet Class A on its own, but fire-treated cedar shake products exist that are tested and rated to carry it. If you want a wood-look roof on a wildland-urban interface property, that's the option to ask about — see our cedar shake page for the full material picture.
