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

Performance you can measure (all climates):
⢠Coated with the AlunarĀ® Coating System (no visible aluminum surface) for continuous finish adhesion and reduced corrosion potential in Arielās persistently damp 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
⢠Tested to 193+ km/h (120+ mph) for severe windstorms, providing a performance margin for gust events that impact Ariel and Cowlitz County
⢠Waterproof installation details minimize leak risk during atmospheric river events that frequently affect Ariel and the lower Lewis River valley
⢠Snow-shedding panel geometry reduces seasonal buildup and helps prevent ice dams during the freezeāthaw cycles seen in inland Washington
⢠Panels and fastener systems retain seal integrity through rapid temperature swings common to Arielās river-valley microclimate
⢠Although Ariel is inland, periodic lowland marine air can reach Cowlitz County; the Alunar® finish and aluminum substrate offer enhanced resistance to salt-driven corrosion compared with bare metals
⢠Smooth coated surfaces and steep panel profiles limit moss and biological growth, making seasonal cleaning in Arielās moss-prone, high-humidity environment simpler
⢠Class A fire-rated available for added ember resistance and reduced ignition risk on wooded or brush-adjacent properties around Ariel
⢠UL 2218 Class 4 impact resistance for protection against hail, falling branches, and storm debris during Pacific Northwest storms
⢠Cool-roof characteristics reduce solar heat gain during summer heat spells, improving attic comfort and lowering HVAC demand in Ariel homes
⢠Engineered for rooftop solar: bracket-compatible attachment points support modern photovoltaic systems and Cowlitz County installation practices
⢠Fully recyclable aluminum supports sustainable lifecycle goals and reduces long-term disposal compared with asphalt roofing
⢠Architectural options replicate slate, cedar shake, and tile while offering standing-seam profiles for contemporary or traditional curb appeal in Ariel neighborhoods
⢠Backed by a lifetime-limited transferable warranty to provide measurable protection and preserve resale value for homeowners in Ariel and throughout Cowlitz County

InterlockĀ® Aluminum Roofing ā all-climates performance specs for Ariel, 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 (wonāt 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. |
