Corrosion Resistant
Aluminum does not develop iron rust
- 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 finished with the Alunar® Coating System (no visible aluminum surface) for multilayer corrosion resistance against coastal moisture.
- Interlocking panel system tested to 120+ mph (193+ km/h) for severe coastal windstorms and gust loads common to exposed San Juan County shorelines.
- Built to resist coastal salt air and marine exposure that accelerate corrosion on conventional roofs — a key benefit for homeowners in Sea Acre.
- Designed for atmospheric-river events: continuous seams, engineered flashings, and high-capacity drainage reduce penetration risk during prolonged heavy rainfall in Sea Acre.
- Surface chemistry and finish reduce biological adhesion to help limit moss and lichen growth on damp Sea Acre roofs, decreasing maintenance frequency.
- Snow-shedding metal panels minimize accumulation and reduce ice-dam risk during episodic snow and freeze–thaw cycles that can affect higher-elevation properties in the region.
- Class A fire-rated available to address ember exposure and provide an extra layer of protection when county advisories or dry periods raise wildfire concerns.
- UL 2218 Class 4 impact resistance for protection against falling branches, airborne debris, and hail events that occur during Pacific storms.
- Cool-roof performance lowers roof-surface temperatures and reduces attic heat gain during occasional summer heat waves, improving indoor comfort and HVAC efficiency.
- Solar-compatible roof geometry and load capacity accept modern bracket-mounted PV arrays without compromising the weatherproof seam integrity.
- Fully recyclable aluminum construction supports long-term sustainability goals and reduces landfill waste compared with tear-off shingle replacements.
- Low-maintenance finish and interlock design significantly cut routine repairs and re-roof cycles versus asphalt shingles in Sea Acre’s high-moisture environment.
- Backed by a Lifetime-Limited transferable warranty that helps protect Sea Acre homeowners’ long-term investment and resale value.

Interlock® Aluminum Roofing — all-climates performance specs for Sea Acre, 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. |
| 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. |
