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

Performance you can measure (all climates):
• Alunar® Coating System protects the substrate with a durable finish (no visible aluminum surface), reducing corrosion risk in humid Houston-area conditions.
• Corrosion-resistant aluminum alloy designed to withstand Gulf-influenced coastal moisture and periodic salt-laden air found across Harris County and Westchase neighborhoods.
• Tested to 193+ km/h (120+ mph) for severe wind events, providing resistance to tropical storm and hurricane-force gusts common to the Houston metro.
• Precision weatherproof seams (profiles: slate, cedar, shake, tile) and mechanical fastening (profile: standing seam) deliver long-term leak protection during wind-driven rain events
• Robust mechanical fastening and engineered trim details minimize fastener pull-through and uplift during sustained high winds.
• Advanced waterproof installation methods reduce ponding and long-term leak potential during Houston’s heavy-rainfall and flash-flood episodes.
• Cool-roof performance lowers roof-surface temperatures to reduce heat gain and improve attic comfort during Gulf Coast heat waves.
• Solar-compatible panel mounting and clearances designed for bracket-mounted photovoltaic systems typical on Westchase homes.
• UL 2218 Class 4 impact resistance helps protect against hail, falling branches, and debris from summer storms and derecho-style gusts.
• Class A fire-rated available for added resilience where ember exposure and structure-to-structure fire risk are a concern in Harris County development zones.
• Low-maintenance finish resists biological staining and reduces routine upkeep compared with asphalt shingles in Westchase’s humid climate.
• Lifetime-limited transferable warranty provides long-term protection and tangible resale value support for Westchase homeowners.
• City-specific — atmospheric-river–style heavy downpours: panel interlock and roof drainage sizing mitigate rapid runoff and reduce infiltration during extreme rainfall events.
• City-specific — coastal salt-air exposure: coated aluminum minimizes galvanic corrosion and paint-system degradation from saline aerosols carried inland to Westchase.
• City-specific — moss and biological growth: smooth coated finish and rapid runoff characteristics limit moss/algae adhesion in warm, humid Westchase conditions.

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