- Specifically designed for Langley roofing conditions, with components selected for Island County’s coastal exposures and variable Puget Sound weather.
- 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 system tested to 193+ km/h (120+ mph) to resist severe storm winds common on Whidbey Island and along Langley’s shoreline.

- Corrosion-resistant aluminum roofing formulated to withstand salt air and marine spray found around Langley and other Island County shorelines.
- Advanced waterproof installation details reduce roof leaks during Langley’s prolonged wet seasons and wind-driven downpours.

Interlock® Aluminum Roofing — all-climates performance specs for Langley, 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:
Thank you for the quality work.
Interlock Roofing worked with us every step of the way, communicated well, and bent over backwards to answer any and all questions we had. Ross was great at communicating all through the process. The new roof is beautiful. The installation crew worked efficiently and answered all questions that came up, took time to make sure we were getting the job we wanted.
I really liked Interlock's product but it was way too expensive. If you are cutting out the middle man it should be feasible to use, but it was not for us. We found someone that is the middle man and they are 1/3 less the cost.
