- Precision weatherproof seams (profiles: slate, cedar, shake, tile) and mechanical fastening (profile: standing seam) deliver long-term leak protection during wind-driven rain events.
- Aluminum coated with the Alunar® Coating System (no visible aluminum surface) for durable, fade-resistant finish and enhanced corrosion protection.

- Designed for mountain-climate thermal cycling—panels tolerate repeated freeze–thaw without cracking or seal failure.
- Wind performance tested to 120+ mph (193+ km/h) to resist strong valley gusts and mountain-channelled windstorms that affect the Leavenworth area.
- Class A fire-rated available to help protect homes in Chelan County from wildfire ember exposure and seasonal brush-fire risk.
- UL 2218 Class 4 impact resistance for protection against hail, falling branches, and storm debris common in Cascade foothill storms.
- Cool-roof performance lowers heat gain during Leavenworth summer heat events and reduces attic temperature swings.
- Solar-compatible roof plane engineered for modern bracket-mounted photovoltaic systems and easy PV integration on Chelan County homes.
- Fully recyclable aluminum construction minimizes lifecycle waste and supports sustainable building choices in the Wenatchee Valley.
- Low-maintenance finish resists delamination and outlasts asphalt shingles under heavy snow, cold winters, and seasonal moisture.
- Warranty-backed lifetime-limited transferable coverage for long-term performance and resale value in the Leavenworth market.
- Built to shed concentrated precipitation from atmospheric-river driven storms that can send heavy runoff into mountain valleys surrounding Leavenworth.
- Leavenworth’s inland location means minimal coastal salt-air exposure; the Alunar® Coating still protects against road salts and localized corrosive agents from winter maintenance.
- Smooth, coated surfaces reduce moss and biological growth on shaded roof planes near the Wenatchee River, cutting cleaning and replacement cycles.
- Precision-fit architectural profiles replicate slate, cedar shake, tile and standing seam aesthetics to complement Leavenworth’s alpine-inspired residential character.

Interlock® Aluminum Roofing — all-climates performance specs for Leavenworth, 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. |
