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

Performance you can measure (all climates):
• Exclusive authorized installer of Interlock® Lifetime Aluminum Roofing Systems for Calgary homeowners and San Augustine County properties
• Aluminum panels coated with the Alunar® Coating System (no visible aluminum surface) for long-term finish retention
• Precision weatherproof seams (profiles: slate, cedar, shake, tile) and mechanical fastening (profile: standing seam) deliver long-term leak protection during wind-driven rain events
• Wind-tested to 193+ km/h (120+ mph) to resist severe windstorms and tropical-storm remnants that affect East Texas
• Advanced waterproof installation reduces leak risk during San Augustine County’s heavy rainfall and humid storm seasons
• Calgary-specific (atmospheric rivers): although Pacific-style atmospheric rivers are not typical here, the system is engineered for intense convective downpours and tropical-moisture events that produce rapid runoff in the region
• Corrosion-resistant aluminum and Alunar® coating resist humidity-driven corrosion and acidic rainfall common to the Pineywoods environment
• Coastal salt air: Calgary is inland with minimal marine salt exposure, but the Alunar® coating provides marine-grade corrosion resistance where waterfront or reservoir exposures occur in San Augustine County
• Panels shed moisture and mitigate freeze–thaw and ice-dam vulnerability during occasional cold snaps in Calgary
• Class A fire-rated available for added protection and ember resistance around forested parcels in San Augustine County
• UL 2218 Class 4 impact resistance for hail, falling branches, and storm debris protection
• Non-porous coated surface discourages moss and algal growth on shaded, humid roof areas common to East Texas yards
• Thermal performance and reflective coating reduce roof-surface heat gain and lower cooling load during Calgary summer heat waves
• Solar-ready roof design and mechanical fastening compatibility for bracket-mounted photovoltaic systems on Calgary homes
• Architectural profiles replicate slate, cedar shake, tile, and standing seam to match rural and historic aesthetics in Calgary neighborhoods
• Lifetime-Limited transferable warranty supports long-term protection and resale value for Calgary and San Augustine County homeowners

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