Interlock® Aluminum Roofing — all-climates performance specs for West Mifflin, Pennsylvania

Spec / RatingClimate / 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 4Hail and impact debris: highest impact classification; resists cracking, splitting, and surface loss common with asphalt under hail strikes.
Snow & ice performance: interlocking, shedding profileHeavy 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 systemHigh heat, intense sun, thermal cycling: coatings resist UV breakdown and temperature-swing fatigue, slowing fading and surface degradation.
Moss / algae resistance: smooth coated surfaceWet 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.
Expected lifespan: 50+ yearsLong-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 transferableLifetime protection + resale value: guarantees long-term material confidence and transfers to future owners.
