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

Performance you can measure (all climates):
• Precision weatherproof seams (profiles: slate, cedar, shake, tile) and mechanical fastening (profile: standing seam) deliver long-term leak protection during wind-driven rain events
• Interlocking panel system tested to 193+ km/h (120+ mph) to resist severe coastal windstorms typical of the Oregon Coast and protect Gearhart rooftops during storm gusts
• Aluminum substrate coated with the Alunar® Coating System (no visible aluminum surface) to provide a durable, colored finish that resists chalking and surface corrosion
• Corrosion-resistant design formulated for salt air and marine exposure along Gearhart’s shoreline, reducing metal degradation from ocean spray and coastal fog
• Engineered waterproof installation details that limit water intrusion during prolonged wet seasons and high wind-driven rain common in Clatsop County
• Panels shaped and installed to promote rapid drainage and snow-shedding, minimizing accumulation and reducing risk of localized snow loads on coastal roofs
• Built to tolerate freeze–thaw cycles and rapid temperature swings that can occur during winter storms on the northern Oregon coast
• Class A fire-rated available for homeowners seeking enhanced ember and flame resistance during dry spells or brush-fire incidents inland from the coast
• UL 2218 Class 4 impact resistance to withstand hail, falling branches, and storm debris encountered during severe weather events
• Cool-roof performance to lower attic heat gain during occasional summer heat waves, improving indoor comfort and reducing HVAC load
• Solar-compatible engineering for secure bracket-mounted photovoltaic system attachment without compromising roof weatherproofing
• Fully recyclable aluminum construction to support durable, long-life roofing with reduced end-of-life waste for Clatsop County properties
• Low-maintenance finish and panel profile that resists moss and organic buildup common in Gearhart’s damp, maritime environment
• Designed to limit routine maintenance needs compared to asphalt shingles in persistent coastal moisture and high-humidity conditions
• Architecturally accurate profiles (slate, cedar shake, tile, standing seam) to preserve design intent and curb appeal for Gearhart homes
• Backed by a Lifetime-Limited transferable warranty to provide long-term protection and resale confidence for homeowners in Gearhart and throughout Clatsop County

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