• Proudly manufactured in Canada by a family‑owned company, serving homeowners across Toronto and South‑Central neighbourhoods
• Authorized installer of Interlock® Lifetime Aluminum Roofing Systems for Toronto residential projects
• The aluminum is coated with the Alunar® Coating System — no visible aluminum surface; durable, uniform finish for long‑term performance
• Precision weatherproof seams (profiles: slate, cedar, shake, tile) and mechanical fastening (profile: standing seam) deliver long-term leak protection during wind-driven rain events
• Designed to shed extreme rainfall and prolonged deluges, including atmospheric‑river driven downpours that can impact the Greater Toronto Area
• Resists corrosion from lakeshore spray and winter road‑salt exposure common along Toronto’s waterfront and arterial routes
• Tested to 193+ km/h (120+ mph) to withstand severe wind events and gusts that affect Toronto roofs
• Advanced waterproof installation details reduce leak risk during Toronto’s heavy spring and fall storms
• Snow‑shedding panels limit accumulation and help mitigate ice‑dam formation during Toronto’s freeze–thaw cycles and winter snow loads
• Built to tolerate rapid seasonal transitions — freeze–thaw, humid summers and wet springs typical of Toronto’s climate
• Class A fire-rated available for enhanced protection during dry spells and urban ember exposure
• UL 2218 Class 4 impact resistance for hail, falling branches, and storm debris protection across Toronto neighbourhoods
• Energy‑efficient cool‑roof performance reduces heat gain during Toronto heat waves and improves attic comfort and HVAC efficiency
• Solar‑compatible design engineered for modern bracket‑mounted photovoltaic systems commonly installed on Toronto homes

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