- Aluminum is coated with the Alunar® Coating System (no visible aluminum surface) to resist corrosion in Grays Harbor County’s persistently damp air and extend finish life in Hillgrove.
- 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) to withstand the severe windstorms that can affect homes across Grays Harbor County and the Hillgrove area.
- Designed for Hillgrove’s atmospheric-river events: high-capacity water shedding and sealed seams reduce interior moisture risk during prolonged heavy rains.
- Formulated to limit corrosion from coastal salt air carried inland from Grays Harbor County shorelines — suitable for Hillgrove properties that see marine aerosol exposure.
- Roof finishes and profiles discourage persistent moss and biological growth on damp Hillgrove roofs, reducing abrasion and water retention on the roof surface.
- Snow-shedding metal panels reduce snow buildup and help prevent ice dams during local freeze–thaw cycles and occasional winter storms near Hillgrove.
- Class A fire-rated available to help protect homes in Grays Harbor County from ember exposure and elevated wildfire-risk periods.
- UL 2218 Class 4 impact resistance provides proven protection against hail, falling branches, and storm debris common to coastal-plain storm systems.

- Mechanically secure fastening and interlock geometry preserve roof integrity under cyclic wind-loads and rapid seasonal transitions experienced in western Washington.
- Solar-compatible decking and attachment points accommodate modern bracket-mounted photovoltaic systems without compromising weatherproofing on Hillgrove roofs.
- Fully recyclable aluminum construction supports sustainable choices for environmentally conscious homeowners in Grays Harbor County.
- Premium architectural profiles (slate, cedar shake, tile, standing seam) recreate traditional aesthetics while meeting local code and neighborhood character in Hillgrove.
- Low-maintenance finish and robust metal substrate are engineered to outlast asphalt shingles in Hillgrove’s high-moisture environment and reduce long-term replacement cycles.
- Backed by a Lifetime-Limited transferable warranty to protect long-term value and resale appeal for Hillgrove homeowners.

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