- 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 color stability and enhanced corrosion resistance.
- Tested to 193+ km/h (120+ mph) to resist severe gusts channeling through the Columbia River Gorge that affect Wishram.
- Panel geometry promotes snow shedding to reduce static roof loads and diminish ice-dam risk during Klickitat County freeze–thaw cycles.
- Class A fire-rated available to help protect homes in wildfire-prone interior Washington and Klickitat County ember-risk periods.
- UL 2218 Class 4 impact resistance for protection from hail, falling branches, and wind-blown debris common in Gorge windstorms.
- Low mass reduces structural load on older Wishram houses while improving seismic and uplift performance.
- Reflective, energy-efficient finishes lower heat gain in summer heat waves and stabilize attic temperatures.
- Solar-compatible roof surface and mounting clearances accommodate modern bracket-mounted photovoltaic systems for rural Klickitat County installations.
- Durable Alunar finish minimizes routine maintenance for remote properties and reduces service visits in winter conditions.
- Engineered for repeated thermal cycling and rapid seasonal swings typical of inland Columbia River communities.
- Smooth Alunar surface discourages moss and lichen adhesion compared with porous shingles (city-specific: moss).
- Weatherproof seam design defends against intense, inland-reaching storm pulses associated with atmospheric-river events that can impact Wishram (city-specific: atmospheric rivers).
- Although inland, Alunar-coated aluminum provides resistance to mineral and occasional river spray deposits along the Columbia—mitigating local salt-related corrosion concerns (city-specific: coastal salt air).
- Backed by a Lifetime-Limited transferable warranty to protect long-term value for Wishram homeowners.

Interlock® Aluminum Roofing — all-climates performance specs for Wishram, 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:
Looks beautiful and can’t wait to see how it fairs in the summer heat and large snowfalls. Communication of start date.
Work on the price, and I think you will get yourself a lot of business. A lot of the labor varies whether you take off the roof or not and includes the cost of removing the roof, and in my case, they would not be taking away anything, so I am still trying to figure out why it would be a two-day job when it's not that big of a roof.
They could have improved their scheduling.
I can't believe how much the roof changed the entire view of the house. There could have been more consistent clean-up during the installation. We have no regrets.
