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

Performance you can measure (all climates):
⢠Proudly manufactured in Canada by a familyāowned company and supplied through exclusive authorized InterlockĀ® installers serving Salmon Arm homeowners
⢠Engineered for Salmon Armās inland mountain climate ā heavy snow loads, repeated freezeāthaw cycles and rapid seasonal shifts across the ShuswapāOkanagan corridor
⢠Precision weatherproof seams (profiles: slate, cedar, shake, tile) and mechanical fastening (profile: standing seam) deliver long-term leak protection during wind-driven rain events
⢠Aluminium is Coated with the Alunar® Coating System (no visible aluminium surface), providing durable colour retention and corrosion resistance
⢠Class A fire-rated available to help protect Salmon Arm homes during dryāseason wildfire and emberārisk periods
⢠Snowāshedding panels reduce rooftop snow load, limit iceādam formation and simplify winter maintenance on steep Salmon Arm roofs
⢠Interlocking panel system tested to 193+ km/h (120+ mph) for severe windstorms and gusts in exposed valley and ridge locations
⢠Advanced waterproofing details resist water ingress during freezeāthaw cycles and peak spring runoff in the Shuswap watershed
⢠UL 2218 Class 4 impact resistance for protection against hail, falling branches and storm debris common to mountaināadjacent properties
⢠Energyāefficient coolāroof performance reduces heat gain during Salmon Arm and neighbouring Okanagan heat waves, improving attic comfort and reducing cooling demand
⢠Solarācompatible roof geometry engineered for modern bracketāmounted photovoltaic systems and local PV installers
⢠Sustainable, fully recyclable aluminium roofing with lower routine maintenance than asphalt shingles in interior highāmoisture conditions
⢠Atmosphericāriver resilience: sealed seams and highācapacity drainage protect Salmon Arm roofs during intense, longāduration precipitation events that increase runoff and wetting
⢠Coastal saltāair note: Salmon Arm is inland, but the AlunarĀ® finish still resists corrosion from lake spray and road deāicing salts where applicable
⢠Moss resistance: smooth, coated surfaces and steep profiles minimise moss and organic buildup on shaded Salmon Arm roofs
⢠Backed by a LifetimeāLimited transferable warranty for longāterm protection and resale confidence

InterlockĀ® Aluminum Roofing ā all-climates performance specs for Salmon Arm, British Columbia
| 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. |
