• 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 is coated with the Alunar® Coating System (no visible aluminum surface) for durable color retention and enhanced corrosion resistance
• Tested to 120+ mph (193+ km/h) for severe coastal windstorms, helping roofs withstand Pacific gust events along Frances’ shoreline
• UL 2218 Class 4 impact resistance for protection against hail, falling branches, and windborne debris during storm events
• Class A fire-rated available for added protection during dry-season ember-risk periods in Pacific County
• Energy-efficient cool-roof performance reduces heat gain during summer heat waves and improves attic comfort in Frances homes
• Solar‑compatible roof geometry engineered for modern bracket-mounted photovoltaic arrays on Frances properties
• Low-maintenance finish resists flaking and coating breakdown in Frances’ persistently damp conditions, reducing upkeep versus asphalt shingles
• Lifetime‑limited transferable warranty supports long-term protection and resale value for Frances homeowners
• Built to manage rapid seasonal transitions and minimize thermal movement from freeze–thaw cycles
• Snow-shedding metal panels reduce buildup and help prevent ice dam formation during occasional cold spells near Frances
• Designed for atmospheric rivers—reinforced seams and rapid runoff channels reduce leak risk during prolonged heavy-rain events common to the Frances coastline
• Coating and detailing engineered for coastal salt air to limit accelerated corrosion from marine exposure along Frances and nearby Pacific County shores

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