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

Performance you can measure (all climates):
• Aluminum panels finished with the Alunar® Coating System (no visible aluminum surface) for long-term colour retention and corrosion resistance on Big Bend homes
• Precision weatherproof seams (profiles: slate, cedar, shake, tile) and mechanical fastening (profile: standing seam) deliver long-term leak protection during wind-driven rain events—critical for spring and fall storms in Waukesha County
• Snow-shedding panel geometry reduces heavy snow buildup and decreases ice-dam risk during Big Bend’s repeated freeze–thaw cycles
• Tested to 193+ km/h (120+ mph) wind performance to resist severe gusts and wind-driven debris common to southeastern Wisconsin storm systems
• Coated aluminum resists corrosion from winter road salt and de-icing chemicals used throughout Big Bend and Waukesha County
• Class A fire-rated available for increased peace of mind, even for properties near wooded lots in the Big Bend area
• UL 2218 Class 4 impact resistance protects roofs from hail, falling branches, and seasonal storm debris
• High reflectivity and emissivity options reduce attic heat gain during Midwest heat waves and improve year-round energy efficiency
• Engineered for simple integration with bracket-mounted photovoltaic systems to support solar installations on Big Bend rooftops
• Low-maintenance finish and inert aluminum substrate minimize moisture-related degradation in Big Bend’s humid summers and wet springs
• Profiles replicate slate, cedar shake, and tile, or offer standing seam lines for traditional-to-modern curb appeal on Waukesha County residences
• Backed by a Lifetime-Limited transferable warranty to support long-term resale value for Big Bend homeowners
• Designed for rapid drainage and tight panel interfaces to handle heavy spring rains and localized runoff in the Big Bend watershed
• City-specific — atmospheric-river–style intense rain events are infrequent but handled by the system’s precision seams and robust underlayment in Big Bend
• City-specific — coastal salt air is not typical for inland Big Bend; however, the Alunar® finish and aluminum substrate also provide marine-grade corrosion resistance where needed and excel against local road-salt exposure
• City-specific — smooth, coated surfaces and steep-shedding profiles inhibit moss and algae growth on shaded, moisture-prone roofs common to Big Bend properties

Interlock® Aluminum Roofing — all-climates performance specs for Big Bend, Wisconsin
| 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. |
