Metal Roofing Built for Rowena's Heavy Rain, Snow Loads, Windstorms & Lifetime Protection

Performance you can measure (all climates):
⢠Tested to 120+ mph wind resistance to withstand the frequent highāwind events that funnel through the Columbia River Gorge and impact Rowena and Wasco County.
⢠Precision weatherproof seams (profiles: slate, cedar, shake, tile) and mechanical fastening (profile: standing seam) deliver long-term leak protection during wind-driven rain events.
⢠The aluminum is Coated with the Alunar® Coating System (no visible aluminum surface).
⢠Corrosionāresistant aluminum defends against moisture and occasional riverborne salt aerosols that can reach homes near the Columbia River at Rowena.
⢠Class A fire-rated available for Wasco County homeowners concerned about seasonal wildfire and ember exposures.
⢠UL 2218 Class 4 impact resistance provides protection from hail, falling limbs, and debris during Gorge storm events.
⢠Panel geometry promotes rapid snow shedding to reduce roof load and minimize iceādam risk during Rowenaās freezeāthaw periods.
⢠Formulated to shed intense precipitation from Pacific atmospheric rivers when they track inland and affect Rowena and surrounding Wasco County.
⢠Energyāefficient reflective coatings help reduce attic heat gain during Eastern Oregon summer heat events and improve yearāround comfort.
⢠Solarācompatible design supports modern bracketāmounted photovoltaic installations on Rowena roofs without compromising weatherproofing.
⢠Nonāporous, coated surfaces limit moss and lichen growth in shaded Gorge microclimates, simplifying maintenance on Rowena properties.
⢠Lightweight aluminum lowers dead load on existing roof structures, often avoiding costly reinforcement in Wasco County homes.
⢠Durable interlocking panels reduce seam exposure and potential leak paths under repeated wind and moisture cycling common in the Gorge corridor.
⢠Engineered to tolerate repeated freezeāthaw cycles and moisture exposure without premature coating degradation in Rowenaās variable seasons.
⢠Backed by a transferable LifetimeāLimited warranty to protect longāterm value for homeowners in Rowena and across Wasco County.

InterlockĀ® Aluminum Roofing ā all-climates performance specs for Rowena, 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 (wonāt 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. (Add exact alloy + thickness for maximum spec proof.) |
| 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. |
