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

Performance you can measure (all climates):
• Proudly manufactured in Canada by a family‑owned company and supplied for homeowners in Windsor and the Annapolis Valley
• Aluminium is coated with the Alunar® Coating System (no visible aluminium surface) to resist coastal moisture and salt exposure
• Precision weatherproof seams (profiles: slate, cedar, shake, tile) and mechanical fastening (profile: standing seam) deliver long-term leak protection during wind-driven rain events
• Interlocking panel system tested to 193+ km/h to withstand severe coastal windstorms that can impact Windsor properties
• Built to shed prolonged, intense rainfall from atmospheric‑river events that affect Windsor and surrounding Annapolis Valley communities
• Corrosion‑resistant finish and sealed joints minimise degradation from Windsor’s proximity to the Minas Basin and salt‑laden coastal air
• Smooth, Alunar®‑finished panels discourage moss and lichen growth on damp Windsor roofs, reducing cleaning and maintenance needs
• Snow‑shedding metal panels reduce accumulation and lower ice‑dam risk during Windsor’s winter snow loads and freeze–thaw cycles
• Roof details and compatible underlayment limit freeze–thaw driven flashing failures and thermal‑cycling fatigue in Nova Scotia conditions
• Class A fire-rated available to address ember exposure and provide added protection during dry spells
• UL 2218 Class 4 impact resistance offers defence against hail, falling branches and storm debris from seasonal wind events
• Cool‑roof performance helps reduce attic heat gain during summer heat waves and improves year‑round comfort and efficiency
• Solar‑compatible profiles accept bracket‑mounted photovoltaic systems without compromising the weatherplane
• Fully recyclable aluminium construction lowers lifetime environmental impact and reduces structural dead load versus asphalt shingles
• Low‑maintenance finish and interlock design extend service life in Windsor’s high‑moisture maritime climate
• Backed by a transferable lifetime‑limited warranty to protect long‑term value for Windsor homeowners

Interlock® Aluminum Roofing — all-climates performance specs for Windsor, Nova Scotia
| 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. |
