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

Performance you can measure (all climates):
• Aluminum panels are Coated with the Alunar® Coating System (no visible aluminum surface) for long-term finish durability in Cornell, Minnesota.
• Precision weatherproof seams (profiles: slate, cedar, shake, tile) and mechanical fastening (profile: standing seam) deliver long-term leak protection during wind-driven rain events.
• Built to shed heavy snowfall and limit accumulation on Cornell roofs, reducing structural snow loads and the risk of ice dams during freeze–thaw cycles.
• Tested to 193+ km/h (120+ mph) for wind resistance, helping Cornell homes withstand severe convective storms and strong gust events.
• Coated aluminum resists corrosion from seasonal moisture and roadside de-icing spray common in inland Minnesota winters.
• Class A fire-rated available to provide ember resistance and elevated fire performance where rural fires or burning debris are a concern.
• UL 2218 Class 4 impact resistance defends against hail, falling branches, and debris during spring and summer storms.
• Cool-roof performance lowers roof-surface temperatures during summer heat spells, improving attic comfort and reducing HVAC load for Cornell homes.
• Engineered for photovoltaic mounting, allowing straightforward integration of bracket-mounted solar on Cornell properties.
• Fully recyclable aluminum construction reduces lifecycle environmental impact and limits replacement waste in rural Minnesota neighborhoods.
• Architectural profiles replicate slate, cedar shake and tile while standing-seam options provide a continuous, low-profile aesthetic suited to Cornell residential styles.
• Continuous mechanical fastening and interlock geometry maintain a secure load path through freeze–thaw movement and seasonal thermal cycling.
• Backed by a Lifetime-Limited transferable warranty to support long-term property protection and resale value for Cornell homeowners.
• Moss-management: in shaded, moisture-prone Cornell yards the Alunar® finish and low-porosity profiles discourage moss adhesion and simplify periodic cleaning.
• Atmospheric-river note (low regional relevance): while atmospheric rivers are not a Pacific phenomenon, the system’s precision seams and mechanical fastening still protect against episodic extreme wind-driven rain events.
• Coastal-salt-air note (not typical for inland Cornell): although marine salt exposure is uncommon in Cornell, the Alunar® coating and coated aluminum provide high resistance should de-icing or salt spray contact roof edges.

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