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

Performance you can measure (all climates):
⢠Proudly manufactured in Canada by a family-owned company and supplied for homeowners across Nepean.
⢠Exclusive authorized installer of Interlock® Lifetime Aluminum Roofing Systems serving Nepean and surrounding Eastern Ontario neighbourhoods.
⢠Built for Eastern Ontario conditions: engineered to withstand heavy snow loads, deep freezeāthaw cycles and rapid spring melt common in Nepean.
⢠Precision weatherproof seams (profiles: slate, cedar, shake, tile) and mechanical fastening (profile: standing seam) deliver long-term leak protection during wind-driven rain events.
⢠Aluminum panels coated with the Alunar® Coating System (no visible aluminum surface) for durable colour retention and corrosion resistance.
⢠Tested to 193+ km/h for severe windstorms, providing verified uplift resistance for roofs across Nepean.
⢠Snow-shedding panel geometry reduces heavy accumulation and helps limit ice-dam formation on Nepean roofs.
⢠Mechanical standing-seam fastening resists thermal cycling and seasonal expansion/contraction in Ottawa Valley temperature swings.
⢠Class A fire-rated available for added safety and homeowner peace of mind.
⢠UL 2218 Class 4 impact resistance to protect Nepean homes from hail, falling branches and storm debris.
⢠Energy-efficient cool-roof performance lowers attic temperatures during summer heat waves and improves yearāround comfort in Nepean houses.
⢠Solar-compatible design engineered for modern bracket-mounted photovoltaic systems on Nepean roof assemblies.
⢠Sustainable and fully recyclable aluminum roofing, reducing long-term waste for environmentally conscious Nepean homeowners.
⢠Atmospheric rivers: while infrequent in Eastern Ontario, the systemās precision seams and AlunarĀ® finish protect against episodic extreme rain and rapid spring runoff in Nepean.
⢠Coastal salt air: Nepean has negligible marine exposure, yet the Alunar® Coating System and alloy selection resist chloride attack from winter road salts used locally.
⢠Moss: low-moisture-shedding profiles and the AlunarĀ® finish minimise moss and lichen growth on shaded roofs in Nepeanās mature neighbourhoods.
⢠Backed by a LifetimeāLimited transferable warranty for long-term protection and resale value in the Nepean market.

InterlockĀ® Aluminum Roofing ā all-climates performance specs for Nepean, 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 (wonāt 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. |
