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

Performance you can measure (all climates):
• Aluminum panels coated with the Alunar® Coating System (no visible aluminum surface) for durable color retention on Detroit roofs
• Precision weatherproof seams (profiles: slate, cedar, shake, tile) and mechanical fastening (profile: standing seam) deliver long-term leak protection during wind-driven rain events
• Tested to 193+ km/h (120+ mph) wind performance to resist sudden gusts and mountain windstorms common around Detroit Lake
• Engineered for high snow loads and frequent freeze–thaw cycles at Detroit’s higher elevations to minimize ice dams and structural snow buildup
• Designed to shed snow quickly, reducing roof load and helping protect rafters and gutters in Marion County mountain homes
• Built corrosion-resistant—ideal for Detroit’s moist, forested environment where prolonged dampness accelerates degradation
• Resists biological growth: profiles and coatings reduce moss and lichen adhesion common on shaded, moss-prone roofs near Detroit Lake
• Precision interlocks and advanced underlayment detail provide long-term leak resistance during atmospheric-river driven downpours that affect western Oregon watersheds
• Class A fire-rated available for added protection during dry spells and ember exposure around forested parcels in Marion County
• UL 2218 Class 4 impact resistance for protection against falling branches, hail, and debris from nearby timbered slopes
• Energy-efficient, cool-roof performance lowers attic heat gain during summer warm periods and improves year-round thermal comfort
• Solar-compatible roofing engineered to integrate with bracket-mounted photovoltaic systems for Detroit homeowners planning PV installations
• Sustainable, fully recyclable aluminum reduces lifecycle environmental impact for environmentally conscious owners in the Detroit area
• Low-maintenance finish and durable panels outlast asphalt shingles in Detroit’s high-moisture, cyclic-freeze environment, backed by a Lifetime-Limited transferable warranty

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