Aluminum does not develop iron rust

  • Alunar® Coating System delivers a durable, colored finish with no visible aluminum surface for long-term corrosion resistance on Moses Lake homes.
  • Precision weatherproof seams (profiles: slate, cedar, shake, tile) and mechanical fastening (profile: standing seam) deliver long-term leak protection during wind-driven rain events.
  • Interlocking panel system tested to 120+ mph (193+ km/h) provides proven resistance to the high wind gusts that can sweep across Grant County’s open plains.
  • Engineered to shed snow and reduce on-roof accumulation, helping manage snow loads and mitigate ice-dam formation during central Washington freeze–thaw cycles.
  • Designed for rapid seasonal swings between hot, dry summers and cold winters typical of Moses Lake, maintaining dimensional stability and finish integrity.
  • Class A fire-rated available for added resilience during regional wildfire-season ember-risk periods affecting parts of Grant County.
  • UL 2218 Class 4 impact resistance reduces the risk of damage from hail, windborne debris, and falling branches common in storm events.
  • High reflectivity and cool-roof performance lower heat gain during Moses Lake summer heat waves and improve attic comfort.
  • Solar-compatible roof system engineered to accept modern bracket-mounted photovoltaic arrays used on residential installations in Moses Lake.
  • Fully recyclable aluminum construction supports sustainable building practices for Grant County homeowners.
  • Low-maintenance finish resists UV degradation and limits dust adhesion in Moses Lake’s semi-arid environment, extending service life compared with asphalt shingles.
  • Robust mechanical fastening and interlock details minimize leak risk during episodic atmospheric river-driven precipitation and rapid snowmelt events that can impact the region.
  • Although Moses Lake is inland with minimal marine exposure, the Alunar®-coated aluminum resists corrosion from any localized salt or mineral carryover related to irrigation and road treatments.
  • Smooth coated surfaces limit moss and biological growth where irrigated shade pockets occur, while Moses Lake’s generally dry climate reduces widespread moss risk.
  • Backed by a transferable lifetime-limited warranty and engineered installation protocols to protect long-term performance and resale value in Moses Lake and throughout Grant County.

Interlock® Aluminum Roofing — all-climates performance specs for Moses Lake, Washington

Spec / RatingClimate / 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 4Hail and impact debris: highest impact classification; resists cracking, splitting, and surface loss common with asphalt under hail strikes.
Snow & ice performance: interlocking, shedding profileHeavy 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 systemHigh heat, intense sun, thermal cycling: coatings resist UV breakdown and temperature-swing fatigue, slowing fading and surface degradation.
Moss / algae resistance: smooth coated surfaceWet 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.
Expected lifespan: 50+ yearsLong-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 transferableLifetime protection + resale value: guarantees long-term material confidence and transfers to future owners.
