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

Performance you can measure (all climates):
• Proudly manufactured in Canada by a family‑owned company, serving homeowners across the Shuswap–Okanagan region
• Engineered specifically for Sicamous’ interior mountain climate — designed to address heavy snow loads, freeze–thaw cycling and rapid seasonal swings
• Precision weatherproof seams (profiles: slate, cedar, shake, tile) and mechanical fastening (profile: standing seam) deliver long-term leak protection during wind-driven rain events
• Coated aluminum with the Alunar® Coating System (no visible aluminum surface) for long-term finish retention and corrosion resistance on lakeside properties
• Tested to 193+ km/h for severe windstorms and mountain‑pass gusts that can affect the Sicamous valley
• Snow‑shedding panels reduce buildup and help prevent ice dams during Sicamous’ winter freeze–thaw cycles
• Built to withstand rapid seasonal transitions and persistent roof moisture common around Shuswap and Mara Lakes
• Atmospheric‑river events: enhanced seam integrity and advanced waterproofing resist prolonged heavy‑precipitation runoff that can reach inland communities like Sicamous
• Coastal salt‑air note: Sicamous is inland with minimal marine salt exposure, yet Alunar® coating still protects waterfront and shoreline homes from lake spray and mineral salts
• Low‑maintenance finish resists moss and other biological growth common on shaded, lakeside roofs
• Class A fire-rated available to provide added protection during interior‑BC dry‑season wildfire and ember‑risk periods
• UL 2218 Class 4 impact resistance for hail, falling branches and storm debris protection
• Energy‑efficient cool‑roof performance reduces heat gain during summer heat waves and improves attic comfort in Sicamous homes
• Solar‑compatible roofing engineered for bracket‑mounted photovoltaic systems popular throughout the Okanagan
• Fully recyclable aluminum supports sustainable building practices for British Columbia homeowners
• Backed by a Lifetime‑Limited transferable warranty for long‑term protection and resale value

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