- 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 Coated with the Alunar® Coating System (no visible aluminum surface) for durable color retention and enhanced corrosion resistance.
- Built for Shaw’s coastal salt exposure: coating chemistry and aluminum substrate minimize pitting and corrosion from salt spray.
- Designed to shed prolonged deluges from atmospheric rivers that impact Shaw and western Skagit County, reducing water intrusion risk at seams and penetrations.
- Minimizes moss and organic buildup on Shaw roofs through smooth coated surfaces and low water-retention profiles that discourage biological growth.
- Tested to resist severe wind uplift up to 193+ km/h (120+ mph) for protection during Puget Sound and Skagit County coastal windstorms.
- Snow-shedding panels and low-profile seams reduce accumulation and ice-dam formation during occasional freeze–thaw cycles and light-to-moderate snow loads.
- Standing-seam mechanical fastening provides continuous attachment and proven uplift resistance for exposed roof planes.
- Class A fire-rated available to address ember exposure and elevated wildfire-season concerns where applicable.
- UL 2218 Class 4 impact resistance against hail, falling branches, and common storm debris.
- Cool-roof performance lowers roof-surface temperatures and reduces attic heat gain during summer warm spells.
- Solar-ready design integrates with bracket-mounted photovoltaic systems without compromising weatherproofing.
- Fully recyclable aluminum construction and long-life finish reduce lifecycle environmental impact versus short-lived roofing alternatives.
- Low-maintenance finish resists flaking, curling, and moisture-driven substrate failure common in coastal Northwest climates.
- Backed by a transferable lifetime-limited warranty for long-term protection and resale confidence.

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

What our customers are saying:
There were no areas, they actually moved up the date, which was a plus. We were very happy with our roof. We are a little sad to see that roof on our old house because we now live in a new house that also needs a roof. When we go to replace this one, we will defiantly call them and use them again.
I am happy with the whole thing.
