Performance you can measure (all climates):
• Designed to shed heavy precipitation common to Clatskanie and Columbia County, reducing ponding and runoff stress on roof assemblies
• 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 resist severe windstorms up to 120+ mph (193+ km/h), helping protect Clatskanie homes in Columbia County’s exposed wind corridors
• Aluminum panels coated with the Alunar® Coating System (no visible aluminum surface) for durable finish retention and corrosion resistance
• Corrosion-resistant formulation defends against coastal salt air carried upriver toward Clatskanie and limits coating breakdown over time
• Specifically engineered to withstand intense atmospheric river downpours that occur in the Pacific Northwest and impact Clatskanie properties
• Reduces moss, lichen, and organic buildup on damp roofs—addressing persistent growth issues on homes around Clatskanie
• Engineered snow-shedding geometry reduces accumulation and lowers ice-dam risk during occasional freeze–thaw cycles
• Class A fire-rated available for added ember-resistance during seasonal dry spells affecting parts of Columbia County
• UL 2218 Class 4 impact resistance provides robust protection from hail, falling branches, and storm debris
• Standing-seam mechanical fastening provides concealed clips and positive load paths to limit uplift during wind events
• Low solar absorptance and reflective coatings improve attic comfort and help limit heat gain during summer heat episodes
• Compatible with modern bracket-mounted photovoltaic arrays for straightforward rooftop solar integration on Clatskanie homes
• Fully recyclable aluminum minimizes lifecycle environmental impact for sustainability-focused homeowners in Columbia County

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