Metal Roofing Built for Provost'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 Alberta, including Provost
• Aluminium substrates coated with the Alunar® Coating System (no visible aluminium surface) for durable colour retention and corrosion resistance
• Designed for Provost’s East‑Central Alberta climate — heavy winter snow loads, rapid freeze–thaw cycles and strong prairie windstorms
• Precision weatherproof seams (profiles: slate, cedar, shake, tile) and mechanical fastening (profile: standing seam) deliver long-term leak protection during wind-driven rain events
• Snow‑shedding panels reduce buildup and help prevent ice dams during spring thaws common in the Battle River valley
• Tested to 193+ km/h for severe windstorms frequently experienced on the Alberta prairies
• Class A fire-rated available
• UL 2218 Class 4 impact resistance for hail, falling branches and farm‑equipment debris
• Corrosion resistance designed to withstand road de‑icing salt, agricultural sprays and other corrosive agents found in East‑Central Alberta
• Energy‑efficient cool‑roof performance reduces summer heat gain and is compatible with modern bracket‑mounted photovoltaic systems
• Fully recyclable aluminium supports sustainable building practices and reduces end‑of‑life landfill impact
• Low‑maintenance finish minimises routine upkeep after winter and limits need for frequent re‑coating or replacement
• Architectural profiles replicate slate, cedar shake and tile to match rural Provost curb appeal while providing technical performance
• While atmospheric rivers are rare this far inland, the system is engineered to resist intense rain‑on‑snow and rapid melt events that can occur in spring around Provost
• No marine salt exposure in Provost, yet the Alunar® coating and aluminium alloy resist local corrosive stresses such as road salts and farm chemicals
• Roof geometry and the Alunar® coating inhibit moss and lichen buildup along Battle River riparian zones, reducing cleaning and biological degradation

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