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

Performance you can measure (all climates):
⢠Precision weatherproof seams (profiles: slate, cedar, shake, tile) and mechanical fastening (profile: standing seam) deliver long-term leak protection during wind-driven rain events.
⢠Aluminum panels coated with the Alunar® Coating System (no visible aluminum surface) resist corrosion and preserve finish in marine-exposed locations.
⢠Tested to 193+ km/h (120+ mph) to withstand severe coastal windstorms common on Whidbey Island.
⢠Built to shed snow and minimize ice-dam risk on roofs subject to occasional freezeāthaw cycles.
⢠Class A fire-rated available for added peace of mind during drier seasonal periods.
⢠UL 2218 Class 4 impact resistance for protection from hail, falling branches, and storm debris.
⢠Low thermal emittance and reflective coatings reduce heat gain during summer heat waves and improve attic comfort.
⢠Engineered for reliable solar compatibility with modern bracket-mounted photovoltaic systems.
⢠Fully recyclable aluminum construction supports long-term sustainability and reduces reroofing waste.
⢠Premium architectural profiles replicate slate, cedar shake, and tile while providing metal durability and curb appeal.
⢠Mechanical standing-seam fastening reduces exposed fasteners and lowers maintenance compared with asphalt shingles.
⢠Backed by a Lifetime-Limited transferable warranty to protect resale value for homeowners in Possession and Island County.
⢠Possession-specific ā designed to handle atmospheric-river-driven deluges and prolonged wet seasons typical of south Whidbey Island.
⢠Possession-specific ā coated panels and corrosion-resistant edges counter ongoing salt-air exposure from marine environments around Possession Point.
⢠Possession-specific ā smooth AlunarĀ® finishes and steep-slope panels inhibit moss and algae retention on damp coastal roofs.
⢠Installation by authorized InterlockĀ® installers ensures factory-compatible tolerances and workmanship tailored to Possessionās coastal conditions.

InterlockĀ® Aluminum Roofing ā all-climates performance specs for Possession, 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 (wonāt 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. |
