Metal Roofing Built for Boring'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 long-term color retention and enhanced 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 193+ km/h (120+ mph) to resist severe windstorms and sudden gusts that can affect homes around Boring and greater Clackamas County
• Handles atmospheric rivers—prolonged, high-intensity rainfall events common to Boring—by shedding water and resisting driven rain without seam compromise
• Although Boring is inland, the Alunar® coating provides corrosion protection for Clackamas County properties exposed to occasional marine‑influenced air or road-salt drift
• Smooth, non‑porous Alunar® finish reduces moss and algae adhesion on shaded Boring roofs, lowering cleaning frequency and preventing moisture trapping
• Built to accommodate freeze–thaw cycles and occasional snow loads in inland Clackamas County; panels shed snow and help minimize ice‑dam formation
• Class A fire-rated available, with assemblies and installation details that reduce ember intrusion risk during Oregon’s dry-season wildfire periods
• UL 2218 Class 4 impact resistance for enhanced protection from hail, falling branches, and debris in wooded, semi-rural Boring neighborhoods
• High-reflectance coating options improve summer thermal performance, reducing heat gain during Pacific Northwest heat waves and improving attic comfort
• Compatible with modern bracket-mounted photovoltaic systems; standing seam and select profiles allow secure, low-penetration PV attachment
• Fully recyclable aluminum construction and durable finish lower lifecycle environmental impact—an advantage for sustainability-focused Clackamas County homeowners
• Premium architectural profiles replicate slate, cedar shake, and tile while concealing metal appearance to match Boring neighborhood aesthetics
• Low-maintenance finish and non-porous panels reduce routine upkeep compared with asphalt shingles in Boring’s moist, moss-prone climate
• Backed by a Lifetime‑Limited transferable warranty to protect long-term investment and resale value for homes in Clackamas County
• Field-proven flashing and attachment details accommodate varied roof pitches, eaves, and prolonged wetting conditions typical on Boring properties

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