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

Performance you can measure (all climates):
• Proudly manufactured in Canada by a family-owned company; authorized Interlock® installers support Ironwood and Metro Vancouver homeowners.
• Aluminum is coated with the Alunar® Coating System (no visible aluminum surface) for long-term colour retention and corrosion resistance on Ironwood roofs.
• Precision weatherproof seams (profiles: slate, cedar, shake, tile) and mechanical fastening (profile: standing seam) deliver long-term leak protection during wind-driven rain events.
• Tested to 193+ km/h (120+ mph) for resistance to severe coastal windstorms and exposed gusts common to Metro Vancouver’s coastal fringe.
• Corrosion‑proof aluminum construction resists salt air and marine exposure on coastal Ironwood properties.
• Designed to withstand atmospheric rivers and prolonged heavy rainfall that affect Ironwood, reducing risk of ponding and seepage.
• Smooth Alunar finish plus interlocking profiles inhibit moss and lichen growth on damp Ironwood roofs, lowering maintenance and chemical cleaning needs.
• Advanced waterproof installation methods maintain long-term leak protection through seasonal wind-driven rain and intense storm events.
• Snow‑shedding metal panels reduce buildup and help prevent ice dams during seasonal snow loads and freeze–thaw cycles.
• Built to handle rapid seasonal transitions, persistent coastal moisture, and cool, damp roof decks typical around Ironwood.
• Class A fire-rated available for enhanced protection during BC dry-season wildfire and ember-risk periods.
• UL 2218 Class 4 impact resistance for defence against hail, falling branches, and storm debris.
• Energy‑efficient cool‑roof performance reduces summertime heat gain and improves attic comfort during heat waves.
• Solar‑compatible profiles engineered for modern bracket‑mounted photovoltaic systems without compromising weatherproofing.
• Sustainable, fully recyclable aluminum backed by a Lifetime‑Limited transferable warranty to protect Ironwood homeowners’ investment.

Interlock® Aluminum Roofing — all-climates performance specs for Ironwood, British Columbia
| 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. |
