Metal Roofing Built for Ocean Shores'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.
• Aluminum panels are coated with the Alunar® Coating System (no visible aluminum surface) to reduce corrosion and coating degradation in coastal conditions.
• Corrosion-resistant finish formulated for Ocean Shores’ marine exposure and salt air from Willapa Bay and the Pacific shoreline.
• Tested to 120+ mph (193+ km/h) for severe coastal windstorms common to Ocean Shores and Grays Harbor County shoreline neighborhoods.
• Designed to shed water and resist leaks during atmospheric rivers and prolonged winter storm events that impact the Olympic Peninsula coast.
• Snow-shedding metal panels reduce buildup and help prevent ice dams during occasional snowfall and freeze–thaw cycles on elevated roofs.
• Class A fire-rated available to address ember exposure and structure-protection concerns during dry spells in Grays Harbor County.
• UL 2218 Class 4 impact resistance for protection from hail, wind-blown debris, and falling branches during seasonal storms.
• Low thermal absorption and reflective finish improve attic comfort and reduce heat gain during rare summer heat waves on the Washington coast.
• Solar-compatible roof geometry and load capacity for modern bracket-mounted photovoltaic systems on Ocean Shores homes.
• Corrosion-proof aluminum substrate provides long service life in salty, humid air—minimizing fastener and flashing corrosion risk.
• Low-maintenance surface resists common coastal roof issues to outlast asphalt shingles in Ocean Shores’ high-moisture environment.
• Moss-resistant coatings and panel profiles limit organic growth on damp roofs and vulnerable eaves common to coastal yards.
• Sustainable, fully recyclable aluminum supports longevity and reduced lifecycle waste for environmentally conscious Grays Harbor County homeowners.
• Backed by a Lifetime-Limited transferable warranty for measurable long-term protection and resale value in the Ocean Shores market.

Interlock® Aluminum Roofing — all-climates performance specs for Ocean Shores, 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 (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. |
