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

Performance you can measure (all climates):
• The aluminum is Coated with the Alunar® Coating System (no visible aluminum surface), delivering long-lasting finish durability against Seaside’s marine environment.
• 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 193+ km/h (120+ mph) to withstand Seaside’s coastal storm winds and gusts.
• Engineered to resist accelerated corrosion from Seaside and broader Clatsop County salt-laden air and spray.
• Designed for Pacific Northwest atmospheric rivers — sealed seams and secure fastening reduce infiltration during intense, prolonged rainfall common in Seaside.
• Protects roof substrates and fasteners from ongoing exposure to coastal salt air and spray that affect Seaside properties.
• Smooth, non-porous Alunar® finish minimizes moss, lichen, and algae growth on Seaside roofs, reducing cleaning frequency and biological degradation.
• Low-friction panels promote snow shedding during occasional Seaside snowfall, helping limit buildup and reduce ice-dam risk.
• Durable seams and coatings resist damage from frequent wet–dry cycles and freeze–thaw transitions found in Clatsop County microclimates.
• Class A fire-rated available for homeowners seeking enhanced ember and ignition resistance where vegetation pockets meet the coast.
• Meets UL 2218 Class 4 impact resistance for protection from hail, falling branches, and storm-borne debris along the shoreline.
• Cool-roof performance lowers summertime heat gain and improves attic comfort during Pacific Northwest heat events.
• Compatible with modern bracket-mounted photovoltaic systems for Seaside homes planning rooftop solar.
• Fully recyclable aluminum construction and extended service life reduce waste and lifecycle environmental impact for Clatsop County homeowners.
• Available in premium architectural profiles that replicate slate, cedar shake, and tile, plus standing seam options for contemporary coastal designs.
• Backed by a Lifetime‑Limited transferable warranty to support long-term protection and resale value in the Seaside market.

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