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

Performance you can measure (all climates):
• Proudly manufactured in Canada by a family‑owned company, available to homeowners in Alma on the Fundy Coast
• Authorized installer of Interlock® Lifetime roofing systems for residential properties in Alma
• Aluminium panels coated with the Alunar® Coating System (no visible aluminium surface) for extended finish durability and corrosion defence
• Precision weatherproof seams (profiles: slate, cedar, shake, tile) and mechanical fastening (profile: standing seam) deliver long-term leak protection during wind-driven rain events
• Corrosion‑resistant aluminium construction reduces routine maintenance compared with uncoated metals in coastal and inland conditions
• Panels tested to resist severe coastal windstorms, demonstrating performance at uplift thresholds of 193+ km/h for enhanced storm resilience
• Advanced waterproof installation lowers leak risk during prolonged heavy rainfall typical of the Fundy Coast seasons
• Snow‑shedding profiles and steep‑slope performance minimise deep snow buildup and help prevent ice dams through freeze–thaw cycles in New Brunswick winters
• High impact resistance (UL 2218 Class 4) protects against hail, falling branches and storm debris from coastal wind events
• Class A fire-rated available for added protection during dry spells and ember‑risk periods
• Cool‑roof properties reduce heat gain in summer, improving attic comfort and lowering seasonal cooling loads
• Fully recyclable aluminium supports sustainability goals for environmentally conscious Alma homeowners
• Low‑maintenance finish resists moss and organic growth common in Alma’s damp, coastal microclimate (city‑specific: moss)
• Designed to withstand atmospheric rivers and prolonged wet periods that influence the Fundy Coast and Alma’s watershed (city‑specific: atmospheric rivers)
• Coating and assembly resist salt‑air corrosion and marine spray exposure along Alma’s shoreline (city‑specific: coastal salt air)
• Solar‑compatible and bracket‑ready for modern photovoltaic systems while preserving seam integrity and warranty coverage

Interlock® Aluminum Roofing — all-climates performance specs for Alma, New Brunswick
| 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. |
