Aluminum does not develop iron rust
- Aluminum roofing panels coated with the Alunar® Coating System (no visible aluminum surface) for long-term corrosion resistance and uniform finish
- Precision weatherproof seams (profiles: slate, cedar, shake, tile) and mechanical fastening (profile: standing seam) deliver long-term leak protection during wind-driven rain events
- Tested to 193+ km/h (120+ mph) to withstand Columbia Basin windstorms common around Eltopia and rural Franklin County properties
- Snow-shedding metal panels reduce buildup and help prevent ice dams during Eltopia’s winter freeze–thaw cycles
- Designed for freeze–thaw durability to resist thermal cycling and membrane stress typical of inland eastern Washington climates
- Class A fire-rated available and detailed to limit ember intrusion for interior Washington wildfire seasons affecting parts of Franklin County
- UL 2218 Class 4 impact resistance for protection against hail, falling branches, and farm-equipment debris in agricultural areas near Eltopia
- Cool-roof thermal performance lowers attic temperatures during summer heat waves across the Columbia Basin, improving comfort and reducing cooling load
- Solar-compatible panel surfaces and fastening details simplify bracket-mounted photovoltaic installations common on Franklin County homes
- Fully recyclable aluminum construction supports sustainable reroofing and reduces end‑of‑life landfill impact
- Low-maintenance Alunar finish resists flaking and fading, decreasing routine upkeep compared with asphalt shingles in Eltopia’s variable seasonal conditions
- Atmospheric rivers: while Eltopia sees fewer direct marine-driven events than western Washington, the precision seams and mechanical fastening still protect roofs during episodic heavy-rain events that move inland
- Coastal salt air: Eltopia is inland with minimal marine salt exposure, yet the Alunar® coating provides robust corrosion protection for any local irrigation or airborne salt traces that can affect Franklin County structures
- Moss and biological growth: smooth coated panels and tight interlocks reduce moss and lichen adherence versus textured shingles, lowering cleaning needs for shaded or irrigated yards around Eltopia
- Premium architectural profiles replicate slate, cedar shake, and tile while offering the standing‑seam option for mechanical fastening and enhanced wind performance
- Backed by a Lifetime‑Limited transferable warranty for long-term protection and resale value in Eltopia and across Franklin County

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

What our customers are saying:
There were no areas, they actually moved up the date, which was a plus. We were very happy with our roof. We are a little sad to see that roof on our old house because we now live in a new house that also needs a roof. When we go to replace this one, we will defiantly call them and use them again.
