• Aluminum panels coated with the Alunar® Coating System (no visible aluminum surface) for durable color retention and reduced corrosion risk
• Coating and alloy selection resist humidity and airborne salts that can be carried inland to Starr County during Gulf storm events
• Engineered waterproof installation methods reduce penetration risk during La Casita’s heavy seasonal thunderstorms and episodic downpours
• Low solar absorptance options improve attic comfort and reduce cooling load during La Casita summer heat waves
• Class A fire-rated available for homeowners who want elevated ember and flame resistance in South Texas brush-prone zones
• UL 2218 Class 4 impact resistance helps protect roofs from hail, windborne debris, and falling limbs during severe storms
• Mechanical standing-seam profiles minimize exposed fasteners and help maintain weathertightness under repeated thermal cycling in warm-humid climates
• Solar-compatible design accommodates modern bracket-mounted PV arrays commonly installed in Starr County residences
• Smooth coated surfaces inhibit biological staining and algae growth that can occur in La Casita’s humid Rio Grande Valley environment

Interlock® Aluminum Roofing — all-climates performance specs for La Casita, Texas
| 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. |
