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

Performance you can measure (all climates):
• Designed for Central Texas climate extremes, balancing humid summers, intense heat waves, and periodic severe thunderstorms
• Aluminum panels coated with the Alunar® Coating System (no visible aluminum surface) for durable, weather-resistant finish
• Precision weatherproof seams (profiles: slate, cedar, shake, tile) and mechanical fastening (profile: standing seam) deliver long-term leak protection during wind-driven rain events
• Engineered to resist corrosion and moisture-related staining common in humid East-Central pockets such as Angelina County
• Tested to 193+ km/h (120+ mph) for severe windstorms and straight‑line gust events that impact Central Texas roofs
• Heat-reflective Alunar® finish helps reduce roof surface temperatures and lowers attic heat gain during frequent Central Texas summer heat waves
• Class A fire-rated available to improve ember resistance and reduce wildfire exposure risk during dry seasons in interior Texas
• UL 2218 Class 4 impact resistance for protection from hail, falling branches, and storm debris during spring and summer severe weather
• Low-profile, snow-shedding panel geometry limits ice-dam risk and performs through occasional freeze–thaw cycles in Central Texas winters
• Mechanical standing-seam option eliminates exposed fasteners, reducing leak points during heavy rainfall and flash-flood events
• Solar-compatible profiles engineered for modern bracket-mounted photovoltaic systems to optimize rooftop PV for Central Texas sun loads
• Lightweight, fully recyclable aluminum roofing minimizes structural load while offering long service life compared with asphalt shingles
• Low maintenance finish resists organic growth and surface degradation in humid, shaded areas often found in Angelina County properties
• Backed by a Lifetime-Limited transferable warranty and tested installation details to support long-term performance for homeowners across Central Texas

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