Metal Roofing Built for Oregon'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, non‑oxidizing finish and long-term color retention.
• Tested for severe wind performance (193+ km/h / 120+ mph) to resist gusts common in Dane County windstorms affecting Oregon homes.
• Snow-shedding panel geometry reduces heavy buildup and helps prevent ice dams under typical Wisconsin snow loads.
• Seams and fastenings accommodate freeze–thaw movement to minimize fatigue and water intrusion over repeated seasonal cycles.
• Class A fire-rated available to support ember resistance and increased protection during dry, elevated fire-risk periods.
• UL 2218 Class 4 impact resistance for protection against hail, falling branches, and storm debris.
• High solar reflectance and emissivity options improve attic comfort and reduce heat gain during Midwest heat waves.
• Engineered for modern bracket-mounted photovoltaic systems; roof-compatible layout simplifies PV attachment on Oregon residences.
• Corrosion‑proof aluminum resists degradation from winter road salts and de‑icing chemicals commonly used in Dane County streets.
• Low-maintenance finish and recyclable materials extend service life beyond asphalt shingles in Oregon’s moist spring and fall seasons.
• Warranty-backed Lifetime‑Limited transferable coverage for long-term protection and resale confidence in Oregon real estate.
• Designed to limit moss and organic growth on damp roofs, reducing cleaning needs for shaded properties in Dane County.
• Built to shed and withstand intense, concentrated downpours (atmospheric‑river–style storm events) that produce rapid runoff in the region.
• Although inland, the system provides marine‑grade corrosion resistance comparable to what coastal alloys offer—useful where salt exposure from roads or landscaping occurs.
• Premium architectural profiles replicate slate, cedar shake, and tile while offering the standing‑seam option for a contemporary look on Oregon homes.

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