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

Performance you can measure (all climates):
• Authorized Interlock® installer serving South Franklin homeowners and properties across Washington County
• Aluminum is Coated with the Alunar® Coating System (no visible aluminum surface)
• Precision weatherproof seams (profiles: slate, cedar, shake, tile) and mechanical fastening (profile: standing seam) deliver long-term leak protection during wind-driven rain events
• Tested to 120+ mph wind ratings for the severe gusts and storm fronts that impact southwest Pennsylvania
• Designed to shed heavy snow and reduce roof snow loads and ice-dam risk during South Franklin’s freeze–thaw cycles
• Panel interlocks and coatings resist fatigue from repeated freeze–thaw and rapid seasonal temperature swings common in Washington County
• Provides long-term leak protection through heavy-rain seasons and spring thaws typical of the region
• Class A fire-rated available for added protection during dry spells and ember-risk periods
• UL 2218 Class 4 impact resistance against hail and falling branches during seasonal storms
• Energy-efficient cool-roof performance lowers attic heat gain during summer heat waves in South Franklin
• Solar-compatible roofing engineered for modern bracket-mounted photovoltaic systems used by local homeowners
• Fully recyclable aluminum with a low lifecycle footprint aligned with Washington County sustainability goals
• Moss: Alunar-coated panels create a smooth, non-porous surface that inhibits moss and biological growth on shaded roofs in South Franklin
• Coastal salt air: South Franklin is inland with minimal marine exposure, but the Alunar finish still provides robust corrosion resistance if localized salt or de-icing exposure occurs
• Atmospheric rivers: although uncommon here, the system’s weatherproof seams and fastening are designed to manage episodic intense rainfall events that can affect the area
• Low-maintenance alternative to asphalt shingles, backed by a Lifetime-Limited transferable warranty to protect long-term value for South Franklin homeowners

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