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

Performance you can measure (all climates):
• Authorized installer of Interlock® Lifetime Aluminum Roofing Systems serving The Dalles and Wasco County
• Designed for The Dalles’ Columbia River Gorge windstorms and high gusts; interlocking panels tested to 120+ mph (193+ km/h) to resist uplift
• Precision weatherproof seams (profiles: slate, cedar, shake, tile) and mechanical fastening (profile: standing seam) deliver long-term leak protection during wind-driven rain events
• Aluminum panels coated with the Alunar® Coating System (no visible aluminum surface) for durable corrosion resistance and a consistent finish
• Class A fire-rated available to address seasonal wildfire ember risk across The Dalles and surrounding rural properties in Wasco County
• Snow-shedding panel geometry reduces buildup and helps prevent ice dams during occasional snow and freeze–thaw cycles inland Oregon experiences
• High-impact resistance (UL 2218 Class 4) protects roofs from hail, falling branches, and storm debris common to Gorge storm events
• Cool-roof performance lowers summer heat gain during Eastern Oregon heat waves, improving attic comfort and reducing cooling load
• Solar-compatible design accommodates modern bracket-mounted photovoltaic systems for homeowners installing PV in The Dalles
• Low-maintenance finish resists flaking and granular loss that accelerate deterioration in Wasco County’s seasonal conditions
• Fully recyclable aluminum supports sustainability goals and reduces long-term waste compared with composite shingles
• Backed by a Lifetime-Limited transferable warranty to protect long-term investment and resale value in The Dalles real estate market
• Atmospheric rivers: panel interlocks and waterproof seams are designed to shed prolonged, heavy rainfall events and reduce ponding on roofs during intense downpours affecting The Dalles
• River/transported marine salts: although inland, the Gorge can receive transported marine aerosols—Alunar-coated aluminum minimizes corrosion risk compared with uncoated metals
• Moss and biological growth: smooth, coated panels shed moisture quickly and reduce persistent wet surfaces, limiting moss and lichen buildup on shaded roofs along the Columbia River Gorge

Interlock® Aluminum Roofing — all-climates performance specs for The Dalles, 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. (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. |
