Aluminum does not develop iron rust

  • 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 120+ mph (193+ km/h) to withstand hurricane-force gusts and tropical windstorms that impact San Marco and Duval County coastlines.
  • Aluminum coated with the Alunar® Coating System (no visible aluminum surface) for multi-layer corrosion resistance.
  • Coastal salt air — Alunar finish and aluminum substrate reduce corrosion and white‑rust risk for San Marco homes near the St. Johns River and tidal inlets.
  • Atmospheric river–style heavy rainbands and prolonged tropical downpours: system resists extended wetting and maintains waterproof performance across extended storm periods.
  • Moss control — smooth Alunar-coated surfaces and low water retention limit moss, algae and organic buildup on shaded San Marco roofs.
  • Interlocking panel geometry and positive engagement reduce uplift and keep panels seated during wind-driven rain and storm surges.
  • Meets UL 2218 Class 4 impact resistance for protection from windborne debris, falling branches and storm impacts common in coastal Duval County.
  • Class A fire-rated available to address ember exposure and local code considerations for urban and riverside San Marco properties.
  • Cool‑roof performance helps lower attic and roof-surface temperatures during Florida heat waves, improving HVAC efficiency and interior comfort.
  • Solar-compatible design accepts modern bracket-mounted photovoltaic systems on standing-seam profiles without compromising seam integrity.
  • Lightweight aluminum minimizes structural load on older San Marco houses while eliminating concerns about snow-load capacity not relevant to Florida.
  • Fully recyclable aluminum and long service life reduce lifecycle material replacement, supporting sustainability goals for Duval County homeowners.
  • Low-maintenance finish plus tight seams reduce leak-related rot and corrosion in high-humidity coastal conditions common to San Marco.
  • Backed by a Lifetime-Limited transferable warranty to protect long-term investment and resale value for San Marco residences.

Interlock® Aluminum Roofing — all-climates performance specs for San Marco, Florida

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.
