- Authorized Interlock® installer serving homeowners in Ceres and throughout Lewis County, providing local specification and installation expertise.
- Designed for inland Western Washington conditions near Ceres: heavy seasonal rainfall, cold snaps and freeze–thaw cycling that stress conventional roofing assemblies.
- Precision weatherproof seams (profiles: slate, cedar, shake, tile) and mechanical fastening (profile: standing seam) deliver long-term leak protection during wind-driven rain events.
- Coated with the Alunar® Coating System (no visible aluminum surface) for enhanced corrosion resistance and consistent finish across Ceres’ damp climate.
- Tested to resist severe windloads—rated to 120+ mph (193+ km/h)—to withstand localized windstorms common to Lewis County valleys and ridge exposures.
- Advanced flashing and drainage detailing reduce risk of moisture ingress during prolonged wet periods that affect Ceres properties.
- Snow-shedding panel geometry reduces rooftop snow accumulation and helps prevent ice dam formation under Ceres’ occasional snow loads and seasonal freeze–thaw cycles.
- Engineered connections and thermal accommodation minimize fatigue at fasteners and seams from repeated freeze–thaw and temperature swings.
- Class A fire-rated available for homeowners in Lewis County who seek additional ember- and fire-resistance during elevated wildfire-risk periods.
- UL 2218 Class 4 impact resistance provides measurable protection against hail, falling branches and storm debris encountered across rural Ceres parcels.
- Cool-roof reflectivity and low thermal mass help reduce heat gain during summer heat waves, improving attic comfort in Ceres residences.
- Photovoltaic-compatible roof surface engineered for modern bracket-mounted solar systems without compromising the panel interlock or weatherproofing.
- Fully recyclable aluminum construction offers a low-maintenance, long-life alternative to asphalt shingles in Ceres’ moisture-prone environment.
- Architectural profiles replicate slate, cedar shake and tile, plus standing seam options, preserving historic or rural curb appeal for homes in Ceres.
- Tailored to local hazards: sheds intense, prolonged rainfall from atmospheric-river events that impact Lewis County and Ceres neighborhoods.
- Low direct marine exposure in Ceres, but the Alunar® coating still resists occasional salt transport during strong Pacific storm events that can reach inland Lewis County.
- Smooth, coated panel surfaces limit moss and organic adhesion common in Ceres’ damp microclimates, reducing cleaning frequency and biological degradation.
- Backed by a Lifetime-Limited transferable warranty to protect long-term performance and resale value for Ceres homeowners.

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