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

Performance you can measure (all climates):
⢠Corrosion-resistant aluminum coated with the AlunarĀ® Coating System (no visible aluminum surface), built to withstand Centennialās persistent moisture and seasonal sun exposure
⢠Precision weatherproof seams (profiles: slate, cedar, shake, tile) and mechanical fastening (profile: standing seam) deliver long-term leak protection during wind-driven rain events
⢠Panels tested to 193+ km/h (120+ mph) for severe windstorms that can impact the Portland metro and East Portland neighborhoods like Centennial
⢠Long-term waterproofing and interlock integrity reduce leak risk during Pacific Northwest atmospheric rivers common to Multnomah County
⢠Profile design sheds light to moderate snow and minimizes buildup to lower ice-dam risk during Centennialās occasional freezeāthaw cycles
⢠Coating and smooth panel surfaces limit moss and biological growth on damp roofs in Centennialās wet, shaded microclimates
⢠Class A fire-rated available for added ember resistance and wildfire-season protection relevant to Multnomah County properties
⢠UL 2218 Class 4 impact resistance to protect against hail, falling branches, and storm debris from local wind events
⢠Standing-seam mechanical fastening reduces fastener fatigue and uplift risk from turbulent gusts across East Portland
⢠Cool-roof performance lowers attic temperatures and reduces heat transfer during regional summer heat waves
⢠Engineered compatibility with bracket-mounted photovoltaic systems for clean PV integration on Centennial homes
⢠Fully recyclable aluminum supports long-term sustainability goals and reduces replacement waste versus asphalt shingles
⢠Low-maintenance surface and interlocks decrease routine upkeep in Centennialās high-moisture environment
⢠Architectural profiles replicate slate, cedar shake, and tile for region-appropriate curb appeal without sacrificing performance
⢠Backed by a lifetime-limited transferable warranty for durable protection and added resale confidence in Centennial real estate

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