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

Performance you can measure (all climates):
⢠Precision weatherproof seams (profiles: slate, cedar, shake, tile) and mechanical fastening (profile: standing seam) deliver long-term leak protection during Timberās wind-driven rain events.
⢠Coated with the Alunar® Coating System (no visible aluminum surface) to limit corrosion and preserve finish on roofs across Timber and Washington County.
⢠Interlocking panel geometry reduces uplift at high wind speeds; system testing to industry wind thresholds supports performance in Timberās seasonal windstorms.
⢠Panels shed snow efficiently to reduce roof loading and limit iceādam formation during Timberās cold snaps and freezeāthaw cycles.
⢠Designed to tolerate rapid wetādry cycles common to the Coast Range foothills around Timber, reducing thermal movement stress and seam fatigue.
⢠Class A fire-rated available for added peace of mind on properties in wildfireāexposure zones around Timber.
⢠Engineered for impact resistance (UL 2218 Class 4 level) to protect against falling limbs and storm debris in forested parcels near Timber.
⢠Coolāroof reflective performance reduces summer heat gain and stabilizes attic temperatures during occasional inland heat waves.
⢠Compatible with modern photovoltaic bracket systems to support rooftop solar installations for Timber homeowners.
⢠Lowāmaintenance aluminum construction resists rot and biological decay common in Washington Countyās moist, wooded settings.
⢠Precision manufacturing and mechanical fastening reduce longāterm maintenance compared with asphalt in Timberās highāmoisture environment.
⢠Backed by a LifetimeāLimited transferable warranty to protect resale value for Timber area properties.
⢠Atmospheric rivers and heavy seasonal downpours: seams and fastenings are specified to maintain watertight integrity under prolonged, highāintensity rainfall typical to the region.
⢠Coastal saltāair exposure is limited in Timber, but where marine influence reaches windward slopes of Washington County, the AlunarĀ® coating system provides enhanced corrosion resistance.
⢠Moss and organic growth control: smooth coated panels and lowāprofile profiles discourage moss adhesion and simplify periodic removal on Timberās shaded, damp roofs.

InterlockĀ® Aluminum Roofing ā all-climates performance specs for Timber, 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. |
