Performance you can measure (all climates):
• Authorized Interlock® Lifetime Aluminum Roofing Systems installer serving Union Gap and Yakima County homeowners.
• Aluminum coated with the Alunar® Coating System (no visible aluminum surface) for long-term finish retention under Yakima Valley sun.
• Precision weatherproof seams (profiles: slate, cedar, shake, tile) and mechanical fastening (profile: standing seam) deliver long-term leak protection during wind-driven rain events.
• Tested to 193+ km/h (120+ mph) to resist severe windstorms and valley gusts common to open exposures around Union Gap.
• Snow-shedding panel geometry reduces roof snow loads and helps prevent ice dams during Union Gap’s winter freeze–thaw cycles.
• Materials and attachment details resist damage from repeated freeze–thaw transitions and temperature swings typical in Yakima County.
• Class A fire-rated available to address wildfire and ember-risk concerns for properties in and around Union Gap.
• UL 2218 Class 4 impact resistance protects against hail, falling branches, and storm debris during central Washington storms.
• Cool-roof performance lowers heat gain during summer heat waves, improving attic comfort and reducing cooling loads for Union Gap homes.
• Solar-compatible surface and attachment points engineered for modern bracket-mounted photovoltaic systems used across Yakima County.
• Fully recyclable aluminum supports lifecycle sustainability goals for environmentally minded Union Gap homeowners.
• Low-maintenance finish and interlock design reduce routine upkeep compared with asphalt shingles in Union Gap’s high-UV, seasonal-climate conditions.
• Designed to handle episodic heavy precipitation and intense wind-driven rain from atmospheric-river remnants that can impact the Yakima Valley.
• Minimal marine salt exposure in Union Gap; nevertheless the Alunar® coating and corrosion-resistant aluminum offer protection against road salts, irrigation minerals, and agricultural sprays common in Yakima County.

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