Metal Roofing Built for Westport'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 wind-driven rain events.
⢠The aluminum is Coated with the Alunar® Coating System (no visible aluminum surface) to provide a durable, non-porous finish that resists chalking and UV degradation.
⢠Tested to 120+ mph (193+ km/h) wind resistance for severe coastal windstorms and Pacific gusts that affect Westport and nearby Grays Harbor County shorelines.
⢠Corrosion-proof aluminum construction minimizes salt-spray and marine-exposure corrosion common on roofs facing Grays Harbor beaches.
⢠Snow-shedding metal panels reduce buildup and help prevent ice dams during occasional freezeāthaw cycles on elevated coastal roofs.
⢠Class A fire-rated available for added structure protection and improved ember resistance during regional dry spells or nearby vegetation fires.
⢠Offers UL 2218 Class 4 impact resistance to protect Westport homes from hail, falling branches, and storm debris.
⢠Energy-efficient cool-roof performance lowers heat gain during summer heat waves and improves attic comfort for Westport residences.
⢠Compatible with bracket-mounted photovoltaic systems for rooftop solar integration without compromising long-term weatherproofing.
⢠Fully recyclable aluminum roofing supports sustainable choices for Grays Harbor County homeowners and reduces landfill waste versus repeated shingle replacement.
⢠Low-maintenance finish and secure panel interlocks reduce routine upkeep compared with asphalt shingles in Westportās moisture-prone climate.
⢠Backed by a Lifetime-Limited transferable warranty to protect long-term value for Westport properties and future owners.
⢠Designed for atmospheric rivers: reinforced seams and drainage handling reduce leakage risk during Westportās episodic, high-intensity downpours.
⢠Formulated to withstand coastal salt air and marine exposure typical of Westportācoating chemistry and alloy selection limit corrosion and finish failure.
⢠Smooth Alunar finish and tight panel geometry inhibit moss, lichen, and algae growth on damp Westport roofs, lowering cleaning frequency and biological deterioration.

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