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

Performance you can measure (all climates):
• Proudly manufactured in Canada by a family‑owned company, serving homeowners in Almonte and eastern Ontario.
• Exclusive authorized installer of Interlock® Lifetime Aluminum Roofing Systems in the Almonte area.
• Designed for Almonte’s inland Eastern Ontario climate — heavy winter snow loads, repeated freeze–thaw cycles and rapid spring runoff.
• 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 finished with the Alunar® Coating System (no visible aluminum surface) for sustained colour retention and scratch resistance.
• Tested to 193+ km/h for extreme wind events produced by strong eastern storm fronts affecting eastern Ontario.
• Snow‑shedding panel geometry reduces heavy accumulation and helps prevent ice dams on Almonte roofs during freeze–thaw periods.
• Class A fire-rated available for added protection during drier windows and ember exposure.
• UL 2218 Class 4 impact resistance to defend against hail, falling branches and storm debris common to regional summer storms.
• Reflective, energy‑efficient surface reduces heat gain during summer heat waves and improves attic comfort in Almonte homes.
• Engineered for solar integration — compatible with modern bracket‑mounted photovoltaic systems for local roof‑mounted arrays.
• Low‑maintenance, fully recyclable aluminum roofing lowers long‑term replacement frequency versus asphalt shingles in eastern Ontario’s moisture cycles.
• Atmospheric rivers and intense rain events: stepped flashings and robust waterproofing manage heavy downpours and protect interiors during east‑moving storm bands.
• Coastal salt air and de‑icing salt exposure: corrosion‑resistant Alunar® finish resists chloride attack from road salt and highway spray even when winter salting is frequent.
• Moss, lichen and biological growth: smooth Alunar® surface and steep panel pitches minimise moss retention on shaded Almonte roofs and speeds natural runoff.
• Backed by a Lifetime‑Limited transferable warranty for long‑term protection and resale value.

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