Metal Roofing Built for Port Hawkesbury's Heavy Rain, Snow Loads, Windstorms & Lifetime Protection
Maritime Metal Roofing Ltd., founded January 4, 2007, is Port Hawkesbury, Nova Scotia’s trusted metal roofing contractor and local installer, and the exclusive authorized installer of Interlock® lifetime aluminum roofing systems. We provide roof replacement and re-roofing for homeowners throughout Port Hawkesbury, delivering heavy-gauge, fire-resistant, energy-efficient cool roofs engineered for performance, beauty, and durability. Interlock’s lifetime aluminum panels—protected by the Alunar® Coating System and backed by a Lifetime Warranty—are ideal for Port Hawkesbury’s coastal conditions and harsh winters: their heavy-gauge construction and interlocking design promote snow-shedding and long-term protection through freeze–thaw cycles, resist corrosion from salt spray and moisture, and withstand high winds better than many traditional roofing materials. Choose the timeless look of slate, cedar shingles, shake, Mediterranean tile, or standing seam with the strength and low-maintenance longevity of metal.

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