• Aluminum coated with the Alunar® Coating System (no visible aluminum surface) for durable, non-oxidizing finishes in humid conditions
• 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 resist windloads of 193+ km/h (120+ mph) to withstand severe gusts associated with regional windstorms and tropical systems
• Advanced waterproof installation details reduce leak risk during Hidalgo County’s heavy rainfall and hurricane-season downpours
• Class A fire-rated available to provide enhanced protection during high-heat, ember-prone periods
• UL 2218 Class 4 impact resistance for improved protection against hail, falling branches, and storm debris
• Rapid drainage and anti-ponding panel geometry minimizes standing water after intense rain events common to the region
• Designed to lower roof-surface temperatures and reduce attic heat gain during prolonged Pharr heat waves
• Engineered for bracket-mounted photovoltaic systems to support rooftop solar installations in Pharr homes
• Fully recyclable aluminum construction for homeowners prioritizing sustainable building materials in Hidalgo County
• Low-maintenance finish resists biological growth and reduces moss buildup in Pharr’s warm, humid environment
• Formulated to withstand occasional salt-laden onshore flow from the Gulf, protecting coastal salts that can reach inland areas

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