Performance you can measure (all climates):
⢠Authorized Interlock® Lifetime Aluminum Roofing Systems installer serving homeowners in Riverview and surrounding Franklin County neighborhoods
⢠Precision weatherproof seams (profiles: slate, cedar, shake, tile) plus mechanical fastening (profile: standing seam) deliver long-term leak protection during wind-driven rain events
⢠Aluminum panels coated with the Alunar® Coating System (no visible aluminum surface) for durable finish and corrosion resistance
⢠Laboratory-verified wind performance to 193+ km/h (120+ mph) to resist regional windstorms and gusts common in the Columbia Basin
⢠Snow-shedding panel geometry reduces rooftop snow loads and helps mitigate ice-dam formation during Riverviewās freezeāthaw periods
⢠Class A fire-rated available to improve ember resistance and passive protection during Franklin Countyās elevated wildfire-risk seasons
⢠UL 2218 Class 4 impact resistance for protection from hail, falling branches, and storm-borne debris
⢠Smooth, coated surfaces limit organic buildup and simplify cleaning in river-adjacent yards and shaded roof zones in Riverview
⢠Cool-roof performance lowers heat gain during summer heat waves, improving attic comfort and reducing cooling demand in inland Eastern Washington
⢠Engineered compatibility with bracket-mounted photovoltaic systems for rooftop solar on Riverview homes
⢠Fully recyclable aluminum construction supports sustainable replacement cycles and reduced landfill waste
⢠Low-maintenance finish designed to outlast asphalt shingles under Riverviewās wide seasonal temperature swings
⢠Transferable Lifetime-Limited warranty for long-term protection and marketable value in Franklin County real estate
⢠Atmospheric-river resilience: precision seams and standing-seam fastening provide added leak protection when strong Pacific moisture bands push inland and produce heavy rain events
⢠Coastal-salt context (local note): although Riverview is inland, the Alunar® coating also resists corrosive agents from road de-icing salts, river spray, and agricultural aerosols common to the regional environment

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