Metal Roofing Built for San Marco'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.
• 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 / 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. |
