Energy Efficient
Reflective cool-roof lowers cooling costs
- 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 are coated with the Alunar® Coating System (no visible aluminum surface) to minimize corrosion and finish degradation in moisture-prone conditions.
- Tested for severe winds to 120+ mph, providing proven resistance to Lewis County windstorm events that can impact Morton homes.
- Installation details focus on advanced waterproofing and interlocks to protect attics and roof assemblies during prolonged Pacific-style rain events common to the region.
- Snow-shedding panel geometry reduces accumulation and lowers risk of structural overload during heavier snow periods in Morton’s Cascade-adjacent elevations.
- Materials and seam design resist damage from repeated freeze–thaw cycles, limiting thermal movement and joint fatigue on roofs around Morton.
- Class A fire-rated available for homeowners seeking enhanced ember resistance and reduced ignition risk during dry summer and nearby forest-fire seasons.
- UL 2218 Class 4 impact resistance improves protection from hail, falling branches, and debris during Lewis County storm episodes.
- Low thermal emittance options and reflective coatings improve attic comfort and reduce peak cooling loads during summer heat waves.
- Solar-compatible layout and attachment details support modern bracket-mounted photovoltaic systems without compromising roof weatherproofing.
- Fully recyclable aluminum construction supports stewardship goals for Lewis County homeowners and long-term material recovery.
- Engineered installation practices reduce maintenance cycles versus conventional asphalt shingles in Morton’s high-moisture environment.
- Designed specifically for atmospheric-river-driven rain events that frequently deliver intense, sustained precipitation to Morton roofs.
- Although Morton is inland, the Alunar® coating still protects against corrosion from road salt, river spray and seasonal moisture—coastal salt air exposure is limited here.
- Panel finishes and tight seam profiles inhibit moss and algae establishment on shaded, moisture-retentive roofs commonly found in Morton neighborhoods.
- Backed by a transferable lifetime-limited warranty to preserve long-term performance and resale value for homes in Morton and greater Lewis County.

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