Performance you can measure (all climates):
• Authorized Interlock® installer serving Bear Creek and Lewis County, with local experience installing to regional 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

• Advanced waterproof installation details minimize leak risk through Bear Creek’s prolonged wet seasons and wind-driven rain
• Snow-shedding panel geometry reduces buildup and helps prevent ice dams under the snow loads and freeze–thaw cycles encountered in inland Lewis County
• Class A fire-rated available to improve ember resistance and roof performance during dry-season wildfire risk in parts of Lewis County
• UL 2218 Class 4 impact resistance for protection against hail, falling branches, and storm debris common after wind events
• Energy-efficient cool-roof performance to limit heat gain during occasional summer heat waves and improve attic comfort in Bear Creek homes
• Solar-compatible system engineered for modern bracket-mounted photovoltaic installations without compromising roof integrity
• Sustainable, fully recyclable aluminum roofing that reduces replacement waste compared with asphalt shingles
• Profiles replicate slate, cedar shake, and tile for architectural appeal while providing the durability Bear Creek homeowners require
• Smooth coated finishes and steep-shedding profiles inhibit moss and lichen growth common in Bear Creek’s damp microclimates
• Designed to handle atmospheric-river events—prolonged, high-intensity rainfall that affects inland Lewis County watersheds and Bear Creek drainage areas
• Coated aluminum resists corrosion from occasional marine salt air that can reach lowland Bear Creek during strong onshore storms
• The aluminum is Coated with the Alunar® Coating System (no visible aluminum surface)

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