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

Performance you can measure (all climates):
• Exclusive authorized installer of Interlock® Lifetime Aluminum Roofing Systems serving homeowners in Clackamas and surrounding neighborhoods
• Designed for Clackamas’s Pacific Northwest climate with emphasis on prolonged wet seasons, seasonal windstorms, and rapid seasonal transitions
• Built to shed extreme rainfall from atmospheric river events that drive severe runoff across Clackamas and Clackamas County

• Moss-resistant finish and low-surface adhesion help limit moss growth on damp Clackamas roofs and simplify routine cleaning
• 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 is Coated with the Alunar® Coating System (no visible aluminum surface) for durable, corrosion-resistant color and finish
• Panels tested to 193+ km/h (120+ mph) for resistance to severe windstorms common to the broader Portland metro and Clackamas County exposures
• Advanced waterproof installation methods reduce leak risk through Clackamas’s extended wet season and heavy frontal storms
• Snow-shedding metal panels reduce accumulation and mitigate ice-dam formation on homes in higher-elevation parts of Clackamas County and seasonal freeze–thaw zones
• Class A fire-rated available, supplying ember resistance and enhanced protection for properties near wildfire-prone foothills of Clackamas County
• UL 2218 Class 4 impact resistance for protection against hail, falling branches, and storm debris in Clackamas neighborhoods
• Energy-efficient cool-roof properties help lower attic temperatures and reduce heat gain during occasional Pacific Northwest heat waves
• Solar-compatible roof surfaces engineered for modern bracket-mounted photovoltaic systems favored by Clackamas homeowners
• Fully recyclable aluminum construction supports sustainable building goals and long-term material stewardship in Clackamas projects

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