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

Performance you can measure (all climates):
⢠Authorized Interlock installers serving Boston Harbor and Thurston County provide certified installation and local code familiarity.
⢠The aluminum is Coated with the Alunar® Coating System (no visible aluminum surface) for a durable, painted finish and enhanced corrosion protection.
⢠Precision weatherproof seams (profiles: slate, cedar, shake, tile) and mechanical fastening (profile: standing seam) deliver long-term leak protection during wind-driven rain events.
⢠Interlocking panel geometry and tested attachment systems rated to 120+ mph (193+ km/h) reduce uplift risk during Puget Sound storm winds.
⢠Engineered panel profiles promote rapid snow-shedding and reduce ice-dam potential during occasional freezeāthaw events in Thurston County.
⢠Designed to resist prolonged wet periods and atmospheric rivers typical of western Washington, minimizing water intrusion risk on Boston Harbor roofs.
⢠Built to limit moss and lichen retention on shaded, moisture-prone roofs common around Boston Harborās marine-influenced neighborhoods.
⢠Coating chemistry and substrate selection specifically mitigate accelerated corrosion from coastal salt air exposure on shoreline properties.
⢠Class A fire-rated available, offering enhanced ember resistance where local summer dryness elevates ignition risk.
⢠UL 2218 Class 4 impact resistance defends against hail, falling branches, and windborne debris encountered during regional storms.
⢠High-reflectivity finishes and ventilated assemblies reduce attic heat gain during Pacific Northwest heat events and improve yearāround comfort.
⢠Solar-compatible substrate and attachment-ready design accommodate modern bracket-mounted photovoltaic systems for Boston Harbor homes.
⢠Low-maintenance, fully recyclable aluminum reduces life-cycle replacement needs compared with organic roofing in the regionās damp climate.
⢠Backed by a Lifetime-Limited transferable warranty to support long-term value and resale confidence for Thurston County homeowners.

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