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

Performance you can measure (all climates):
⢠Aluminum is Coated with the Alunar® Coating System (no visible aluminum surface) for durable color retention and surface protection
⢠Precision weatherproof seams (profiles: slate, cedar, shake, tile) and mechanical fastening (profile: standing seam) deliver long-term leak protection during wind-driven rain events
⢠Engineered to withstand South Wenatcheeās inland freezeāthaw cycles and thermal movement without premature panel fatigue
⢠High snow-shedding design reduces sustained roof loads and lowers ice-dam risk for homes throughout Chelan County
⢠Class A fire-rated available to increase resistance to embers and wildfire exposure during Central Washington dry seasons
⢠UL 2218 Class 4 impact resistance for protection against hail, falling limbs, and storm-borne debris
⢠Wind-performance specifications address gusts and windstorms that affect rooftops along the Columbia River corridor near South Wenatchee
⢠Cool-roof properties decrease summer heat gain during Chelan County heat waves and improve attic temperature control
⢠Solar-ready compatibility with bracket-mounted photovoltaic systems for streamlined solar installs on South Wenatchee roofs
⢠Fully recyclable aluminum construction supports long-term sustainability goals for Wenatchee Valley homeowners
⢠Low-maintenance finish resists staining and reduces routine upkeep on river-adjacent properties in South Wenatchee
⢠Atmospheric-river resilience: system resists episodic heavy precipitation and rapid runoff events that occur seasonally in the Wenatchee area
⢠Minimal marine-salt concern inland: Alunar® coating plus aluminum base minimizes corrosion risk where coastal salt air exposure is negligible compared with coastal zones
⢠Resists moss and lichen accumulation in shaded, moisture-prone roof zones near the Columbia River, reducing retained moisture and deterioration
⢠Architecturally accurate profiles replicate slate, cedar shake, and tile aesthetics while delivering metal durability for South Wenatchee curb appeal
⢠Backed by a lifetime-limited, transferable warranty to protect long-term investment and resale value for South Wenatchee homeowners

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