Metal Roofing Built for Stillwater'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 durable, low-gloss finish and corrosion resistance
• Corrosion-resistant finish tailored for riverfront humidity along the St. Croix in Stillwater and nearby Washington County homes
• Built to shed heavy Minnesota snow loads, reducing rooftop accumulation and structural stress during Stillwater winters
• Engineered to limit ice-dam formation and withstand frequent freeze–thaw cycles typical of Washington County spring thaws
• Tested to resist severe wind events up to 193+ km/h (120+ mph), lowering risk from intense gusts and storm fronts in the St. Croix valley
• Interlocking panel geometry and continuous seams maintain watertight integrity through prolonged cold-weather storms and melting events
• Class A fire-rated available, providing an added layer of ember and flame protection where needed
• UL 2218 Class 4 impact resistance for robust defense against hail, falling branches, and storm debris
• High-reflectance finish improves cool-roof performance to reduce attic heat gain during summer heat spells and lower cooling loads
• Solar-ready design: engineered mounting compatibility for modern photovoltaic bracket systems without compromising weatherproofing
• Fully recyclable aluminum construction supports sustainable choices for environmentally conscious Washington County homeowners
• Architectural profiles replicate slate, cedar shake, and tile to preserve historic character on Stillwater homes while delivering metal durability
• Standing-seam mechanical fastening minimizes exposed fasteners and accommodates thermal movement for long-term panel stability
• Lifetime-limited transferable warranty protects long-term ownership value and resale prospects in the Stillwater market
• Installation by authorized professionals ensures proper ventilation, insulation detailing, and local code compliance for cold-climate performance

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