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

Performance you can measure (all climates):
• Aluminum panels Coated with the Alunar® Coating System (no visible aluminum surface) for long-term color retention and corrosion resistance in Trafton’s maritime‑influenced climate
• Precision weatherproof seams (profiles: slate, cedar, shake, tile) and mechanical fastening (profile: standing seam) deliver long-term leak protection during wind-driven rain events
• System tested to 193+ km/h (120+ mph) to resist severe windstorms that impact Trafton and parts of Snohomish County
• Atmospheric‑river protection: oversized drainage details and interlock integrity reduce backflow and ponding during prolonged downpours common to the region
• Designed to resist corrosion from marine‑influenced salt air that can reach Trafton and low‑lying Snohomish County neighborhoods during strong onshore storms
• Moss control: coated smooth surfaces and rapid water shedding limit moss adhesion on Trafton roofs and simplify periodic soft‑wash maintenance
• Snow‑shedding panel geometry lowers accumulation and reduces ice‑dam potential during Snohomish County freeze–thaw cycles and occasional snowfall
• Class A fire-rated available with ember‑resistant details to support home‑hardening measures during dry, elevated‑risk periods
• UL 2218 Class 4 impact resistance guards against hail, falling branches and storm debris for reliable performance after severe weather
• Cool‑roof reflectivity and thermal performance reduce attic heat gain during summer warm spells, improving indoor comfort and HVAC efficiency in Trafton homes
• Solar‑compatible profiles engineered for bracket‑mounted photovoltaic systems, with attachment points specified for local installation loads
• Fully recyclable aluminum and a durable finish lower lifetime material replacement and reduce environmental footprint for Snohomish County homeowners
• Low‑maintenance finish resists peeling and blistering in persistent damp conditions typical of Trafton, minimizing routine upkeep
• Premium architectural profiles replicate slate, cedar shake and tile, plus standing‑seam options, blending technical performance with neighborhood curb appeal
• Backed by a Lifetime‑Limited transferable warranty to protect long‑term value for homeowners in Trafton and elsewhere in Snohomish County

Interlock® Aluminum Roofing — all-climates performance specs for Trafton, Washington
| 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. |
