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

Performance you can measure (all climates):
• 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 enhanced corrosion resistance and a consistent, low-gloss finish
• Tested to 193+ km/h (120+ mph) to withstand severe windstorms common to Stittsville and surrounding Eastern Ontario storm tracks
• Snow-shedding metal panels reduce heavy roof loads and help prevent ice dams during Stittsville’s freeze–thaw cycles and sustained snowfalls
• Durable panel construction resists cracking, buckling and fatigue from repeated freeze–thaw stresses typical of Ottawa-area winters
• Precision interlocks and engineered details minimise roof penetrations and improve long-term resilience to wind-driven snow and sleet
• Class A fire-rated available for added peace of mind during dry periods or when ember exposure is a concern
• UL 2218 Class 4 impact resistance protects against hail, falling branches and storm debris encountered in east‑Ontario weather events
• Energy-efficient surface performance reduces heat gain during summer heat waves and lowers attic temperatures in Stittsville homes
• Solar‑compatible roof geometry and load capacities facilitate modern bracket-mounted photovoltaic installations
• Coating and alloy selection resist corrosion from road‑salt splash and urban airborne contaminants common in winter maintenance around Stittsville (in lieu of marine salt exposure)
• Designed to shed heavy rainfall from intense eastern storm systems and prolonged downpours that can impact Stittsville’s drainage infrastructure
• Smooth coated panels and raised seams reduce moss and biological growth on shaded roofs, improving roof hygiene in Stittsville’s mature neighbourhoods
• Fully recyclable aluminum construction supports long-term sustainability goals and reduces lifecycle environmental impact
• Low‑maintenance finish and durable profile extend service life well beyond asphalt shingles in Eastern Ontario’s variable climate
• Backed by a Lifetime‑Limited transferable warranty to support long‑term protection and resale value for Stittsville homeowners

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