- Interlocking panel geometry and factory-toleranced connections reduce thermal movement stress in Warren’s cool, moisture-heavy climate.
- Snow-shedding panel contours reduce accumulation and help prevent ice-dam formation during the occasional freeze–thaw cycles seen in Columbia County.

- Low-maintenance finish resists delamination and eliminates routine granule loss associated with asphalt shingles in high-moisture areas.

- Built to shed heavy rainfall from atmospheric-river events; precision seams and drainage paths minimize ponding and leak potential during prolonged storms in Warren.

Interlock® Aluminum Roofing — all-climates performance specs for Warren, Oregon
| 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:
Apparently there was a hold up at the Canadian border that delayed us a day. After that everything went quickly and smoothly. Victor and his crew were awesome. We added solar tubes with the roof.
As an appraiser this type of roofing is nice to see. It does not add dollar per dollar in value to your home. Price is a little steep.
