Interlock® Aluminum Roofing — all-climates performance specs for Midland, 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:
Ivan replaced our exhaust vent on the roof that had some leaking issue. We were impressed with his professionalism, courtesy and fixing the problem to our utmost satisfaction. We certainly would recommend him and the company for any roofing issues being it a new roof or repairs.
It was a great experience,but we decided to go with another company.
Interlock could have improved by being cleaner and by making sure they cleaned up all of the products before they left.
None Great job n negative comments
Initial communication with staff unreliable. I left messages that were never answered. Too many times the person I needed to speak with was out to lunch and at unusual hours of the day.
Ross was a good guy, I wish I could do more business with him in the future.
The salesperson could have elaborated further on things like the appearance of the piping and ventilation.The pictures he showed me depicting the front side of the house featured much less stuff sticking out than the finished product. The pictures gave me the impression that nothing would be sticking out, when this did not end up being the case.

The one thing that I didn't like was that I felt pressured to buy on the spot.
The one thing that I didn't like was that I felt pressured to buy on the spot. We would rather collect facts from vendors to consider our chooses. We would have never excepted that even if the price had been good because of the pressure to buy.
