  • Engineered for Bath, NH’s mountain-influenced climate — heavy snowfall, deep freeze–thaw cycles, and rapid temperature swings across Grafton County.
  • Precision weatherproof seams (profiles: slate, cedar, shake, tile) and mechanical fastening (profile: standing seam) deliver long-term leak protection during wind-driven rain events.
  • Interlocking panel system tested to 193+ km/h (120+ mph) for severe wind events, providing measurable uplift resistance for Bath roofs exposed to nor’easters and strong seasonal gusts.
  • Coated with the Alunar® Coating System (no visible aluminum surface) for long-term finish durability and reduced chalking on Bath homes.
  • Built to shed heavy New Hampshire snow — panels promote rapid snow movement to lower roof loads and reduce manual clearing in Bath and surrounding Grafton County.
  • Designed to reduce ice-dam formation and resist freeze–thaw damage through continuous metal coverage and secure fastening details.
  • Class A fire-rated available for added protection on properties near forested parcels and fuel loads typical of inland New Hampshire.
  • UL 2218 Class 4 impact resistance for protection against hail, falling limbs, and seasonal debris encountered in northern New England storms.
  • Energy-efficient cool-roof performance lowers attic heat gain during summer warm spells and improves year‑round comfort in Bath residences.
  • Solar-compatible roof platform engineered for modern bracket-mounted photovoltaic systems without compromising weather-tight integrity.
  • Sustainable, fully recyclable aluminum construction supports long-term asset value and lowers lifecycle environmental impact for Bath homeowners.
  • Resists intense rainfall from atmospheric-river–style storm bands and prolonged downpours—precision seams and installation details preserve watertight integrity during extreme wet events.
  • Coastal salt-air resilience: although Bath is inland, the system resists corrosion from road de-icing salts and occasional riverborne aerosols for homes near local waterways.
  • Moss and biological-growth resistance tailored for Bath’s shaded, damp roof slopes—coated surfaces and steeper profiles limit retention and simplify cleaning.
  • Precision architectural profiles replicate slate, cedar shake, tile, and standing seam to maintain New Hampshire character while meeting local building expectations.
  • Backed by a Lifetime‑Limited transferable warranty to protect long-term investment and resale value in the Bath, NH market.

Interlock® Aluminum Roofing — all-climates performance specs for Bath, New Hampshire

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.
