⢠Aluminum panels coated with the Alunar® Coating System (no visible aluminum surface) for durable, fade-resistant finishes
⢠Precision weatherproof seams (profiles: slate, cedar, shake, tile) and mechanical fastening (profile: standing seam) deliver long-term leak protection during wind-driven rain events

⢠Built to shed heavy rainfall and standing moisture from prolonged wet periods common to Western Washington
⢠Designed to withstand atmospheric river events that bring extended, high-intensity rain to Glenoma and surrounding areas
⢠Although Glenoma is inland, the Alunar® finish provides corrosion resistance where occasional marine salt exposure or road-salt drift may occur in Lewis County
⢠Finish, panel slope, and tight seams minimize moss and algae accumulation on roofs in Glenomaās damp, shaded sites
⢠Snow-shedding panels reduce buildup and lower the risk of ice dams during winter snow loads and subsequent freezeāthaw cycles
⢠Structural capacity sized to manage inland snow loads and rapid temperature swings typical of foothill and forested properties near Glenoma
⢠Class A fire-rated available to help protect forest-edge homes during regional dry-season wildfire and ember-risk periods
⢠UL 2218 Class 4 impact resistance for protection against hail, falling branches, and debris from local storm events
⢠Energy-efficient cool-roof performance helps limit heat gain during occasional Pacific Northwest heat waves and improves attic comfort

InterlockĀ® Aluminum Roofing ā all-climates performance specs for Glenoma, 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. |
