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

Performance you can measure (all climates):
⢠Precision weatherproof seams (profiles: slate, cedar, shake, tile) and mechanical fastening (profile: standing seam) deliver long-term leak protection during wind-driven rain events
⢠The aluminum is Coated with the Alunar® Coating System (no visible aluminum surface) for durable color retention and corrosion resistance
⢠Interlocking panel system tested to 193+ km/h (120+ mph) resists severe Puget Sound wind gusts and coastal storm loading that can affect Raft Island roofs
⢠Built to shed extreme rainfall from atmospheric rivers that pass through Pierce County, maintaining watertight performance on Raft Island homes
⢠Corrosion-resistant design and coated finishes minimize saltāair pitting and fastener degradation from marine exposure around Raft Island and nearby shorelines
⢠Smooth low-porosity surfaces reduce moss and algae growth common on Raft Islandās damp roofs, lowering cleaning and maintenance frequency
⢠Snow-shedding metal panels reduce accumulation and help prevent ice dams during occasional Puget Sound freezeāthaw cycles
⢠UL 2218 Class 4 impact resistance protects against hail, falling branches, and storm debris typical of shoreline properties
⢠Class A fire-rated available to address ember exposure and provide additional assurance during dry seasonal periods
⢠Energy-efficient reflective properties reduce heat gain during summer warm spells and improve attic comfort for Raft Island residences
⢠Solar-compatible system engineered to integrate with bracketāmounted photovoltaic arrays without compromising the coated finish
⢠Low-maintenance aluminum resists rot, delamination and prolonged moisture exposureāoutlasting asphalt shingles in Pierce Countyās moist climate

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