Metal Roofing Built for Bordeaux's Heavy Rain, Snow Loads, Windstorms & Lifetime Protection

Performance you can measure (all climates):
• Aluminum panels are coated with the Alunar® Coating System (no visible aluminum surface) for long-term finish integrity and corrosion resistance.
• Precision weatherproof seams (profiles: slate, cedar, shake, tile) and mechanical fastening (profile: standing seam) deliver long-term leak protection during wind-driven rain events.
• Interlocking panel geometry and high-tension fasteners tested to 120+ mph (193+ km/h) resist regional windstorms that affect Thurston County properties.
• Advanced waterproof installation details reduce leak risk through Bordeaux’s prolonged wet seasons and heavy fall–winter precipitation.
• Snow-shedding panel profiles minimize rooftop accumulation and lower ice-dam potential during inland freeze–thaw episodes.
• Class A fire-rated available for homeowners seeking added ember- and flame-resistance during dry summer periods.
• UL 2218 Class 4 impact resistance protects against falling branches and storm debris common in Bordeaux’s forested lots.
• Energy-efficient cool-roof performance helps limit attic heat gain during occasional Pacific Northwest heat events and improves year-round comfort.
• Solar-compatible surface engineered to accept modern bracket-mounted PV systems without compromising roof integrity.
• Fully recyclable aluminum roofing supports sustainable choices for environmentally conscious Bordeaux homeowners.
• Premium architectural profiles replicate slate, cedar shake, and tile while offering standing-seam options for a technical, low-profile aesthetic.
• Low-maintenance finish reduces the need for frequent repairs compared with asphalt shingles in Thurston County’s damp environment.
• Designed to shed intense rainfall from atmospheric-river events typical to Western Washington, reducing ponding and run-off stress on roof assemblies.
• Coating and alloy selection help mitigate corrosion from occasional coastal salt air intrusion in low-lying Thurston County corridors near estuaries.
• Panel geometry and Alunar® surface inhibit moss adhesion; routine low-pressure cleaning preserves drainage and prolongs service life in Bordeaux’s humid, moss-prone microclimates.

Interlock® Aluminum Roofing — all-climates performance specs for Bordeaux, Washington
| Spec / Rating | Climate / Risk Factor + What It Solves |
|---|---|
| Wind resistance: 120+ mph (193+ kph) | Extreme wind, hurricanes, storm uplift: full interlocking attachment helps prevent blow-offs, edge lifting, and panel loss in high-gust events. |
| Fire rating: Class A (with proper assembly) | Wildfire, embers, radiant heat, chimney sparks: non-combustible roof assembly provides the highest residential fire protection rating. |
| Hail resistance: UL 2218 Class 4 | Hail and impact debris: highest impact classification; resists cracking, splitting, and surface loss common with asphalt under hail strikes. |
| Snow & ice performance: interlocking, shedding profile | Heavy snow, freeze-thaw, ice dams: smooth aluminum sheds snow efficiently and the interlocking design helps block water intrusion when melt-refreeze cycles occur. (Final snow-load capacity depends on roof structure and local code.) |
| Corrosion resistance: aluminum (won’t rust) | Salt air, coastal humidity, wet climates: aluminum naturally resists rust and corrosion, reducing long-term failure risk in marine or high-moisture environments. |
| Heat / UV durability: baked-on coating system | High heat, intense sun, thermal cycling: coatings resist UV breakdown and temperature-swing fatigue, slowing fading and surface degradation. |
| Moss / algae resistance: smooth coated surface | Wet shade, organic growth: low-porosity metal surface gives moss/algae less to grip, reducing staining and maintenance. |
| Material: heavy-gauge aluminum roof profiles (Slate / Shake / Shingle / Tile / Standing Seam) | All-season structural stability: lightweight, dent-resistant metal system stays stable through large hot-cold swings and severe weather. (Add exact alloy + thickness for maximum spec proof.) |
| Expected lifespan: 50+ years | Long-term durability across climates: avoids re-roof cycles typical of shorter-life materials, even in high-stress environments. |
| Warranty: Lifetime-Limited, non-prorated + 50-year transferable | Lifetime protection + resale value: guarantees long-term material confidence and transfers to future owners. |
