Metal Roofing Built for San Fernando's Heavy Rain, Snow Loads, Windstorms & Lifetime Protection

Performance you can measure (all climates):
• Interlock® Lifetime Aluminum Roofing Systems available to San Fernando homeowners and property owners across Starr County
• Designed for San Fernando’s South Texas climate — prolonged summer heat, high humidity, and intense thunderstorm downpours
• Precision weatherproof seams (profiles: slate, cedar, shake, tile) and mechanical fastening (profile: standing seam) deliver long-term leak protection during wind-driven rain events
• The aluminum is Coated with the Alunar® Coating System (no visible aluminum surface)
• Corrosion-proof aluminum roofing designed to resist coastal salt air and marine exposure that can travel inland to low-lying Starr County neighborhoods
• Proven performance during atmospheric-river and tropical-rainband downpours — tight seams and robust fastening reduce water intrusion during extended heavy-precipitation events
• Tested to 193+ km/h (120+ mph) for severe windstorms to help San Fernando roofs withstand gusts from Gulf-origin weather systems
• Advanced weather-tight installation methods provide long-term leak protection through San Fernando’s storm season and wind-driven rain
• Rapid rain-shedding panel geometry minimizes ponding and standing water on low-slope assemblies after intense local storms
• Class A fire-rated available for added resilience where dry-season brush fires or ember exposure can threaten edge-of-town properties
• UL 2218 Class 4 impact resistance for hail, windborne debris, and fallen limbs during severe thunderstorms
• High solar reflectance and emissivity lower heat gain during San Fernando heat waves and reduce attic cooling loads
• Solar-compatible roof surface engineered for modern bracket-mounted photovoltaic systems without compromising weatherproofing
• Durable coatings limit moss and biological growth on shaded eaves and gutters in humid pockets of San Fernando
• Architectural profiles replicate slate, cedar shake, and tile while providing standing-seam mechanical fastening for lasting curb appeal in local neighborhoods
• Backed by a Lifetime-Limited transferable warranty to support long-term protection and resale value in San Fernando and Starr County

Interlock® Aluminum Roofing — all-climates performance specs for San Fernando, 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. |
