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

Performance you can measure (all climates):
• Precision weatherproof seams (profiles: slate, cedar, shake, tile) and mechanical fastening (profile: standing seam) deliver long-term leak protection during wind-driven rain events
• Aluminum coated with the Alunar® Coating System (no visible aluminum surface) for superior corrosion resistance and durable color retention
• Engineered for New City’s continental climate, addressing heavy snowfall, freeze–thaw cycles, and wide seasonal temperature swings
• High snow-shedding panels help reduce roof snow loads and limit prolonged ice buildup on New City homes
• Tested to 120+ mph wind resistance to withstand severe gusts and storm-driven winds that affect the Cook County area
• Class A fire-rated available for enhanced protection during dry spells and ember exposure
• UL 2218 Class 4 impact resistance to resist hail and storm debris common in Midwest thunderstorms
• Interlocking panel geometry and continuous mechanical fastening minimize exposed fasteners and uplift risk during rapid wind shifts
• Cool-roof performance lowers attic heat gain during Midwest heat waves, improving year-round comfort and HVAC efficiency
• Solar-compatible design supports modern bracket-mounted photovoltaic systems without compromising weatherproof seams
• Low-maintenance, fully recyclable aluminum roofing that outlasts asphalt shingles through New City’s wet-snow seasons and seasonal cycling
• Backed by a transferable lifetime-limited warranty to protect long-term investment and resale value
• Designed to resist corrosion from road-salt spray and repeated freeze–thaw exposure typical of Cook County streets and suburban roofs
• Standing-seam option provides continuous mechanical fastening and extra seam protection during rapid thaws and heavy spring rains

Interlock® Aluminum Roofing — all-climates performance specs for New City, Illinois
| 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. |
