Metal Roofing Built for Richmond'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 Richmond homeowners
• Authorized Interlock® installer serving Richmond and surrounding Eastern Ontario communities
• Precision weatherproof seams (profiles: slate, cedar, shake, tile) and mechanical fastening (profile: standing seam) deliver long-term leak protection during wind-driven rain events
• The aluminum is coated with the Alunar® Coating System (no visible aluminum surface) for durable finish and improved corrosion resistance
• Panels tested to 193+ km/h (120+ mph) to resist severe windloads from eastward storm fronts impacting Richmond
• Advanced waterproof installation details reduce leak risk during Richmond’s prolonged rain events and spring thaw cycles
• Snow‑shedding panel geometry reduces roof snow loads and helps prevent ice dams during Richmond’s freeze–thaw winters
• Designed for rapid seasonal transitions and persistent moisture typical of Eastern Ontario roofs
• Atmospheric‑river resilience: precision seams and high‑capacity drainage handle intense, concentrated rainfall and rapid melt events that can affect Richmond
• Coastal salt‑air note: Richmond’s inland setting limits marine exposure, but the Alunar® coating still protects roofs near rivers, culverts and areas exposed to road‑salt spray
• Moss and biological‑growth control: smooth Alunar® finish and steep‑shedding panels limit moss, lichen and algae in Richmond’s shaded, damp microclimates
• Class A fire-rated available to address ember and dry‑season fire concerns in Eastern Ontario
• UL 2218 Class 4 impact resistance provides protection against hail, falling branches and common storm debris around Richmond properties
• Energy‑efficient reflective properties reduce attic heat gain during summer heat episodes and improve year‑round comfort for Richmond homes
• Fully recyclable aluminum construction, solar‑compatible for bracket‑mounted PV, and backed by a transferable Lifetime‑Limited warranty to protect long‑term value in Richmond

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