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

Performance you can measure (all climates):
• Aluminum panels coated with the Alunar® Coating System (no visible aluminum surface) for durable color retention and corrosion resistance
• 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 120+ mph (193+ km/h) windloads for severe storm events that can impact Linn County properties
• Advanced interlocking panel installation minimizes water intrusion during Shedd’s prolonged wet seasons and wind-driven rains
• Snow-shedding metal panels reduce buildup and help prevent ice dams during occasional freeze–thaw cycles in inland Oregon
• Class A fire-rated available with ember-resistant details to address summer wildfire risk in the Willamette Valley and Linn County
• UL 2218 Class 4 impact resistance for protection from hail, falling branches, and storm debris common after intense storms
• Cool-roof performance and reflective finishes lower attic temperatures and reduce heat gain during regional heat waves
• Low-maintenance finish resists peeling and delamination in Shedd’s moist, cool climate—outlasting asphalt shingles with fewer repairs
• Solar-compatible roof surface engineered for modern bracket-mounted photovoltaic systems and simplified rooftop PV integration
• Fully recyclable aluminum construction supports sustainable choices for environmentally conscious homeowners in Shedd
• Architectural profiles that replicate slate, cedar shake, and tile, plus standing seam options, for long-term curb appeal in Linn County neighborhoods
• Backed by a Lifetime-Limited transferable warranty to protect resale value and long-term investment for Shedd homeowners
• Built to shed extreme rainfall from atmospheric river events that periodically affect the Willamette Valley and Shedd-area drainage systems
• Smooth, coated surface and rapid drainage discourage moss and organic growth that thrive in Shedd’s damp winter conditions
• Shedd is inland with limited marine salt exposure; nevertheless the Alunar® coating provides corrosion resistance if occasional coastal aerosols or transported salt reach lower Linn County areas

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