Metal Roofing Built for White Salmon'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 corrosion protection and color retention
⢠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 severe wind loads (120+ mph) ā engineered to withstand the Columbia Gorge windstorms that reach White Salmon rooftops
⢠Snow-shedding panel geometry reduces buildup and helps prevent ice dams during Klickitat County freezeāthaw cycles and occasional heavy snow
⢠Rapid drainage and sealed seams protect against prolonged saturation during atmospheric river downpours that affect White Salmon
⢠Class A fire-rated available to improve roof resilience during regional wildfire and ember-risk periods in Klickitat County
⢠UL 2218 Class 4 impact resistance for protection from hail, falling branches, and debris during intense wind events
⢠Cool-roof performance lowers attic temperatures during summer heat waves, improving comfort and reducing cooling load in White Salmon homes
⢠Designed for direct integration with bracket-mounted photovoltaic systems for clean, structural solar installs
⢠Low-maintenance, non-porous finish resists moss and organic growth common in White Salmonās damp winter conditions
⢠Fully recyclable aluminum supports sustainable roof replacement and lifecycle performance goals
⢠Standing-seam mechanical fastening minimizes exposed penetrations, reducing potential leak points on steep Gorge roofs
⢠Corrosion-resistant Alunar® finish also protects against intermittent salt-laden air transported through the Columbia Gorge during strong westerlies
⢠Architectural profiles replicate slate, cedar shake and tile aesthetics while providing metal-level durability suited to Klickitat County architecture
⢠Backed by a transferable Lifetime-Limited warranty to quantify long-term protection and preserve resale value

InterlockĀ® Aluminum Roofing ā all-climates performance specs for White Salmon, Washington
| 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. |
