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

Performance you can measure (all climates):
• Authorized Interlock® installer serving Cary and McHenry County homeowners
• Aluminum panels coated with the Alunar® Coating System (no visible aluminum surface) for a durable, fade- and corrosion-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
• Class A fire-rated available for enhanced resistance to ember exposure and supplemental fire-protection requirements
• Engineered for heavy Midwestern snow loads and repeat freeze–thaw cycles that affect Cary-area roofs, reducing structural stress and ice-dam formation
• Snow-shedding panel geometry and smooth Alunar® surfaces accelerate melt-off and minimize persistent snow buildup
• Resists corrosion from road de-icing salts used across McHenry County—Alunar® coating preserves finish and fastener integrity where splash and runoff occur
• Tested interlock systems and mechanically fastened standing seams provide wind-uplift resistance appropriate for northern Illinois severe gust events
• Interlocking design minimizes water infiltration during heavy spring and summer thunderstorms common to the region
• UL 2218 Class 4 impact resistance for protection against hail and falling branches during storm seasons
• Cool-roof reflective options reduce attic heat gain during Illinois summer heat waves and improve HVAC efficiency
• Solar-compatible profiles and standing-seam mounting paths accommodate modern PV systems without compromising weatherproofing
• Low-porosity Alunar® finish inhibits moss and biological growth in shaded, humid microclimates found on Cary properties
• Fully recyclable aluminum construction lowers lifecycle waste compared with composite shingles
• Backed by a Lifetime-Limited transferable warranty and local authorized support to protect your Cary home’s long-term value

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