• Proudly manufactured in Canada by a family-owned company, serving British Columbia homeowners
• Aluminum panels coated with the Alunar® Coating System (no visible aluminum surface)
• Precision weatherproof seams (profiles: slate, cedar, shake, tile) and mechanical fastening (profile: standing seam) deliver long-term leak protection during wind-driven rain events
• Engineered for Lumby’s interior Okanagan climate — designed to withstand significant snow loads, freeze–thaw cycles and wide seasonal temperature swings
• Tested to 193+ km/h for severe windstorms and valley gusts that can affect the North Okanagan near Lumby
• Snow-shedding panel geometry reduces buildup and helps prevent ice dams on Lumby roofs during heavy snowfall and melt cycles
• Advanced waterproof installation methods provide durable leak resistance during intense rainfall and atmospheric-river-driven downpours that can reach the Okanagan interior
• Class A fire-rated available to improve defence against ember exposure and wildfire risk during dry-season events around Lumby
• UL 2218 Class 4 impact resistance for protection from hail, falling branches and storm debris common in forested mountain-adjacent lots
• Cool-roof performance reduces solar heat gain during Okanagan summer heat waves and improves attic temperature control in Lumby homes
• Solar-compatible design engineered for bracket-mounted photovoltaic systems typically used on Okanagan residential roofs
• Fully recyclable aluminum supports sustainability goals for environmentally conscious homeowners in the Okanagan region
• Premium architectural profiles replicate slate, cedar shake, tile and standing seam to match Lumby’s mountain‑cottage and valley aesthetic

Interlock® Aluminum Roofing — all-climates performance specs for Lumby, British Columbia
| 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. |
