Metal Roofing Built for Madoc'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 Madoc and southeast Ontario
• Authorized Interlock® Lifetime Aluminum Roofing installers serving the Madoc area
• Designed for Madoc’s inland southeast Ontario climate—heavy snow loads, recurrent freeze–thaw cycles and wide seasonal temperature swings
• Snow‑shedding panel geometry reduces accumulation and helps prevent ice dams during Madoc’s sustained winter storms and thaws
• 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 panel system tested to 193+ km/h (120+ mph) for severe windstorms across open township exposures
• Built to withstand intense rainfall and atmospheric‑river driven deluges that can produce rapid runoff in southeast Ontario and Madoc’s watershed areas
• Alunar® Coating System (no visible aluminum surface) protects the aluminum substrate from corrosion and surface abrasion in rural exposures
• Although Madoc is inland with minimal marine salt air, the Alunar® finish still guards metal surfaces from roadside and agricultural salt exposure
• Low‑permeability joints and dedicated drainage paths minimise water entrapment and cyclic freeze–thaw damage typical of southeastern Ontario roofs
• Class A fire-rated available to provide ember resistance during warm, dry periods and to complement local wildfire‑preparedness measures
• UL 2218 Class 4 impact resistance for protection against hail and falling branches from mature hardwoods around Madoc properties
• Energy‑efficient cool‑roof performance reduces summer heat gain and improves attic comfort during regional heat waves
• Designed to resist moss and organic growth on shaded roofs, lowering cleaning frequency and reducing retained moisture on Madoc homes
• Fully recyclable aluminum construction, engineered solar compatibility for bracket‑mounted PV, and a Lifetime‑Limited transferable warranty for long‑term value in Madoc and the surrounding southeast Ontario region

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