- Designed for homeowners in Upper Salmon Junction (Pacific County) — local topography and county maps confirm the community’s location within Pacific County, WA.
- Aluminum panels finished with the Alunar® Coating System (no visible aluminum surface) for long-term colour retention and reduced surface corrosion in damp Pacific Northwest conditions.
- 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 tested to 193+ km/h (120+ mph) for measured wind-uplift resistance against strong storm winds that affect coastal Pacific County and nearby inland areas.
- Built to resist atmospheric‑river events: engineered drainage, sealed interlocks and professional installation reduce risk of water intrusion during extended, high‑volume rain episodes common to the region.
- Formulated for coastal salt exposure — Alunar®-coated aluminum and corrosion‑resistant components limit degradation from marine salt air that can travel inland from Pacific County shorelines.
- Controls for moss and organic growth: low‑porosity finish, smooth panel surfaces and standard roof pitches help limit moss adhesion in Upper Salmon Junction’s persistently damp, shaded conditions.
- Snow‑shedding panel design mitigates buildup and lowers ice‑dam potential during occasional freeze–thaw cycles in the area.
- Class A fire-rated available to address ember exposure and structure protection concerns where vegetative or seasonal fire risk exists within the county.
- UL 2218 Class 4 impact‑resistant option provides tested resistance to hail, falling branches and common storm debris.
- Reduces attic heat gain with cool‑roof performance, improving comfort and lowering summer cooling load during regional warm spells.
- Solar‑ready roof surface and mounting compatibility for bracket‑mounted PV arrays without compromising panel integrity.
- Fully recyclable aluminum construction offers long service life and reduced lifecycle environmental impact for sustainability‑minded Pacific County homeowners.
- Architectural profiles replicate slate, cedar shake and tile with standing‑seam options for authentic curb appeal tailored to homes in Upper Salmon Junction.

Interlock® Aluminum Roofing — all-climates performance specs for Upper Salmon Junction, 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. |
| 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. |
