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

Performance you can measure (all climates):
• Specifically suited to Westwood (Pittsburgh), in Allegheny County, where inland seasonal snow, freeze–thaw cycles and humid summers are common.
• Precision weatherproof seams (profiles: slate, cedar, shake, tile) and mechanical fastening (profile: standing seam) deliver long-term leak protection during wind-driven rain events.
• Panels coated with the Alunar® Coating System — aluminum is fully coated with no visible aluminum surface for improved color retention and corrosion resistance.
• Class A fire-rated available for homeowners seeking higher fire performance without sacrificing aesthetics.
• UL 2218 Class 4 impact resistance for protection against hail, falling branches and storm debris.
• Engineered to accommodate Westwood’s freeze–thaw cycles and temperature swings, reducing seam stress and the risk of thermal movement over time.
• Snow-shedding panel geometry helps lower rooftop snow loads and mitigates ice-dam formation during Pennsylvania winters.
• Interlocking panel design resists uplift during localized windstorms that pass through the Pittsburgh region.
• Rigid metal surface and Alunar® finish limit moss and algae adhesion on shaded roofs common in Westwood’s tree-lined neighborhoods, reducing cleaning frequency.
• Energy-efficient finish options reduce summer heat gain, improving attic comfort and lowering cooling load for Westwood homes.
• Solar-compatible panel geometry and load-bearing design allow modern bracket-mounted PV systems without compromising weatherproofing.
• Low-maintenance metal construction resists rot and moisture degradation that shortens asphalt shingle life in Allegheny County’s humid conditions.
• Sustainable, fully recyclable aluminum minimizes long-term roof replacement waste and supports eco-conscious home upgrades.
• Multiple architectural profiles (slate, cedar shake, tile and standing seam) preserve Westwood curb appeal while meeting local style and resale expectations.
• Backed by a lifetime-limited transferable warranty to protect long-term value and provide reassurance for Westwood homeowners.

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