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

Performance you can measure (all climates):
⢠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 panels Coated with the Alunar® Coating System (no visible aluminum surface) for durable color retention and surface corrosion resistance
⢠Tested to withstand 120+ mph (193+ km/h) gusts for windstorm resistance suited to Western Washington exposure
⢠Designed to handle atmospheric river events that bring prolonged, moistureāladen storms to the Platinum area
⢠Snow-shedding panel geometry reduces roof snow loads and helps prevent ice dams during freezeāthaw cycles at higher elevations in Lewis County
⢠Class A fire-rated available to address seasonal ember and wildfire risk in inland sections of Lewis County and surrounding timbered slopes
⢠Coastal salt-air resistance: while Platinum is inland, the Alunar® finish resists chloride-driven corrosion for properties nearer estuaries or tidal influence in Lewis County
⢠UL 2218 Class 4 impact resistance against hail, falling branches, and storm debris common after Pacific frontal systems
⢠Interlocking panel engagement and engineered attachment minimize uplift and maintain seam compression under severe gusts and windborne debris
⢠Lowāmaintenance finish and smooth profile inhibit moss and lichen adherence common in Western Washingtonās damp, shaded roofs
⢠Coolāroof reflective properties reduce daytime heat gain during summer warm spells and improve attic thermal performance for Platinum homeowners
⢠Solarācompatible panel geometry accepts modern bracketāmounted PV systems when installed per manufacturer guidelines
⢠Fully recyclable aluminum and long service life reduce lifecycle waste compared with organic shingle replacements in highāmoisture climates
⢠Backed by a LifetimeāLimited transferable warranty to preserve longāterm protection and resale value for Platinum homeowners

InterlockĀ® Aluminum Roofing ā all-climates performance specs for Platinum, 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. |
