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

Performance you can measure (all climates):
• Manufactured by Interlock, a family‑owned company with decades of metal‑roof expertise
• Engineered for Rhododendron’s Mount Hood foothills—built to resist heavy snow loads, freeze–thaw cycling, and mountain windstorms
• 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 corrosion resistance and long-lasting finish retention
• Interlocking panel system tested to 193+ km/h (120+ mph) for severe ridge‑line gusts and storm winds common above Rhododendron
• Advanced waterproof installation methods provide long-term protection against Clackamas County’s prolonged wet seasons and saturated soils
• Snow‑shedding panel geometry minimizes accumulation and helps prevent ice dams during heavy snowfall and repeated freeze–thaw cycles
• Built to tolerate rapid seasonal transitions and persistent roof dampness typical of the Mt. Hood corridor around Rhododendron
• Class A fire-rated available to reduce ember and ignition risk during summer dry spells in Clackamas County wildland‑interface areas
• UL 2218 Class 4 impact resistance for protection from hail, falling branches, and storm debris from nearby forest canopy
• Energy‑efficient cool‑roof performance lowers heat gain during occasional summer heat waves and stabilizes attic temperatures
• Solar‑compatible engineering for modern bracket‑mounted photovoltaic systems on Rhododendron residences
• Sustainable, fully recyclable aluminum supports environmentally conscious homeowners across Clackamas County
• Specifically designed for atmospheric‑river events—prolonged, high‑volume rainfall in western Oregon—by shedding large runoff loads and resisting leakage
• Corrosion‑resistant finish also defends against any episodic coastal salt exposure carried inland by major Pacific storms to higher‑exposure sites in the county
• Low‑absorption finish and steep‑shedding profiles reduce moss and lichen growth on damp, shaded roofs in Rhododendron, cutting maintenance and prolonging service life

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