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

Performance you can measure (all climates):
• Aluminum is Coated with the Alunar® Coating System (no visible aluminum surface) to minimize corrosion and preserve finish on Bethany rooftops.
• 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 120+ mph (193+ km/h) resist severe wind gusts common to Pacific Northwest storm systems impacting Washington County.
• Advanced waterproof installation reduces leak risk during Bethany’s heavy rains and atmospheric-river driven storm events.
• Snow-shedding metal panels reduce buildup and help prevent ice dams through occasional freeze–thaw cycles experienced in the region.
• Designed to limit moss and algae retention on damp, shaded roofs—helpful for Bethany homes with mature trees and prolonged moisture.
• Corrosion-resistant aluminum guards properties in Washington County with occasional river or marine spray exposure near river corridors.
• Class A fire-rated available to improve ember resistance and reduce wildfire vulnerability during dry summer periods.
• UL 2218 Class 4 impact resistance for protection from hail, falling branches, and storm debris common to local windstorms.
• Energy-efficient cool-roof characteristics lower heat gain during summer heat waves and improve attic comfort for Bethany residences.
• Solar-compatible roof system engineered for bracket-mounted photovoltaic arrays, simplifying PV installation on Washington County homes.
• Sustainable, fully recyclable aluminum roofing supports long-term stewardship goals for environmentally conscious Bethany homeowners.
• Low-maintenance finish reduces routine upkeep compared with asphalt shingles in Bethany’s high-moisture climate.
• Architectural profiles replicate slate, cedar shake, and tile while offering standing-seam mechanical fastening options for technical roof assemblies.
• Backed by a Lifetime-Limited transferable warranty for long-term protection and resale value in the Bethany market.

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