  • 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 enhanced corrosion resistance in moisture-prone environments.
  • Independently tested for extreme wind performance (120+ mph / 193+ km/h), engineered to resist storm gusts and wind-driven rain common to the lower Columbia River corridor.
  • Advanced waterproof installation details reduce leak risk during Rainier’s heavy-rain seasons and atmospheric-river events that impact Columbia County.
  • Snow-shedding panel geometry minimizes snow buildup and mitigates ice-dam formation during occasional winter loads and freeze–thaw cycles.
  • Designed for rapid seasonal transitions and prolonged damp conditions typical of Rainier-area roofs to limit moisture intrusion and substrate degradation.
  • Class A fire-rated available for homeowners seeking ember-resistant performance during elevated wildfire-risk periods in Columbia County.
  • UL 2218 Class 4 impact resistance for protection from hail, falling limbs, and debris carried by windstorms.
  • Cool-roof reflectivity options reduce heat gain during summer heat waves and lower attic peak temperatures in Rainier homes.
  • Engineered mounting compatibility with modern photovoltaic brackets for safe, secure solar installations on local roofs.
  • Fully recyclable aluminum construction supports sustainable building choices and reduces long-term replacement waste.
  • Low-maintenance finish resists moss and biological growth; panel profiles discourage retention of organic material common in Rainier’s damp microclimate.
  • Formulated to withstand coastal salt air that travels upriver to Rainier, limiting corrosion where marine aerosols affect exposed surfaces.
  • Backed by a Lifetime-Limited transferable warranty to protect resale value and provide long-term assurance for Rainier and Columbia County homeowners.

Interlock® Aluminum Roofing — all-climates performance specs for Rainier, Oregon

Spec / RatingClimate / 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 4Hail and impact debris: highest impact classification; resists cracking, splitting, and surface loss common with asphalt under hail strikes.
Snow & ice performance: interlocking, shedding profileHeavy 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 systemHigh heat, intense sun, thermal cycling: coatings resist UV breakdown and temperature-swing fatigue, slowing fading and surface degradation.
Moss / algae resistance: smooth coated surfaceWet 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+ yearsLong-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 transferableLifetime protection + resale value: guarantees long-term material confidence and transfers to future owners.
