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

Performance you can measure (all climates):
• Interlocking aluminum panels coated with the Alunar® Coating System (no visible aluminum surface) for durable color retention on Maplewood roofs
• Precision weatherproof seams (profiles: slate, cedar, shake, tile) and mechanical fastening (profile: standing seam) deliver long-term leak protection during wind-driven rain events
• Tested to 193+ km/h (120+ mph) to withstand severe storm winds and gusts common along Maplewood’s Colvos Passage shoreline
• Marine-grade corrosion resistance engineered for prolonged exposure to salt air and coastal moisture around Maplewood and Pierce County
• Designed to manage atmospheric river events and prolonged, wind-driven rainfall that impact Maplewood’s wet seasons
• Panel geometry encourages rapid snow shedding and reduces ice-dam formation during occasional Pierce County freeze–thaw cycles
• Class A fire-rated available to address ember and dry-season fire-risk concerns in Pierce County-adjacent areas
• UL 2218 Class 4 impact resistance for protection from hail, falling branches, and storm debris during Pacific Northwest windstorms
• Cool-roof finishes and high-reflectance coatings reduce heat gain during summer heat waves and improve attic comfort in Maplewood homes
• Solar-compatible profiles engineered for bracket-mounted photovoltaic systems without compromising roof waterproofing
• Non-porous Alunar® finish limits moss and biological buildup on shaded Maplewood roofs, reducing cleaning frequency
• Fully recyclable aluminum substrate and a low-VOC coating system lower lifecycle environmental impact for environmentally conscious Maplewood homeowners
• Premium architectural profiles replicate slate, cedar shake, and tile to match local aesthetics while meeting regional code expectations
• Backed by a transferable Lifetime-Limited warranty to protect long-term performance and resale value for Maplewood properties

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