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

Performance you can measure (all climates):
• Aluminum is Coated with the Alunar® Coating System (no visible aluminum surface) — durable color retention and corrosion protection suited to Kuster homes
• 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 panels tested to 193+ km/h (120+ mph) to resist severe windstorms and gusts that impact Kuster properties
• Advanced waterproof installation designed for Kuster’s heavy rainfall and atmospheric river events, minimizing water intrusion risk
• Snow-shedding metal panels and high-load capacity reduce snow buildup and help prevent ice dams during Kuster-area freeze–thaw cycles
• Engineered surface finishes and panel geometry limit moss and algae retention on roofs in Kuster’s damp, low-sun periods
• Corrosion-resistant aluminum and Alunar® coating mitigate salt-air and marine exposure where coastal influences reach Lewis County properties
• UL 2218 Class 4 impact resistance for protection from hail, falling branches, and storm debris common in Lewis County windstorms
• Class A fire-rated available to improve ember resistance and homeowner protection during regional wildfire-risk periods
• Precision interlocks and controlled fastening patterns minimize thermal movement noise and preserve watertight seals through seasonal temperature swings
• Cool-roof reflectivity and emissive Alunar® finish reduce heat gain during Pacific Northwest heat waves and improve attic comfort in Kuster homes
• Solar-compatible panel design supports modern bracket-mounted PV systems without compromising weatherproofing or roof integrity
• Low-maintenance, fully recyclable aluminum construction built to outlast asphalt shingles in Kuster’s high-moisture environment
• Architectural profiles that replicate slate, cedar shake, tile, and standing seam preserve curb appeal across Kuster and nearby Lewis County neighborhoods
• Lifetime-limited transferable warranty and certified installation practices protect long-term value for homeowners in Kuster

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