Metal Roofing Built for Alliston'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 homeowners in Alliston and South‑Central Ontario
• Exclusive authorized installer of Interlock® Lifetime Aluminum Roofing Systems for Alliston residences and nearby rural properties
• Precision weatherproof seams (profiles: slate, cedar, shake, tile) and mechanical fastening (profile: standing seam) deliver long-term leak protection during wind-driven rain events
• Interlocking panels tested to 193+ km/h (120+ mph) for resistance to severe wind events common to exposed South‑Central Ontario locations
• Aluminum coated with the Alunar® Coating System (no visible aluminum surface) for enhanced corrosion resistance and long-term colour retention
• Designed for inland South‑Central Ontario climate: engineered to withstand heavy snow loads and repeated freeze–thaw cycles experienced around Alliston
• Snow‑shedding panels reduce rooftop accumulation and help prevent ice dam formation during Alliston winters
• Robust waterproof details and installation methods reduce leak risk from spring thaw and high‑intensity rainfalls
• Class A fire-rated available for extra protection during rare dry periods or ember exposure on rural properties
• UL 2218 Class 4 impact resistance to protect Alliston roofs from hail, falling branches, and storm debris
• Energy‑efficient cool‑roof performance lowers attic heat gain during summer heat spikes in the region
• Solar‑compatible roof plane engineered for modern bracket‑mounted photovoltaic systems on Alliston homes
• Low‑maintenance, fully recyclable aluminum roofing that outlasts asphalt shingles in South‑Central Ontario’s moist‑freeze cycles
• Atmospheric rivers — panels and seam design manage intense short‑duration rainfall and rapid runoff events that can affect Southern Ontario
• Coastal salt air — while Alliston is inland and marine exposure is not a primary concern, the Alunar® finish still provides robust corrosion protection where needed
• Moss management — smooth, coated surfaces and rapid snow‑melt reduce persistent moss and lichen growth on shaded Alliston roofs

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