Interlock® Aluminum Roofing — all-climates performance specs for Cavalero, 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:
did great
The crew didn't know until that morning they were coming over to my project.
All went according to the installation plan and since no one can control weather conditions I can't think of anything to improve. Interlock has a very satisfied customer here!
It went well.
The only step that was missing was notification of actual start date. Otherwise, the rest of the process was fine.
If you promise a gift card for having a salesman over, follow through. No card
I am very impressed with the quality of your metal roof and would have loved to have gone with it. Now I know that I should quadruple the amount of money I need to save up if I expect to have a metal roof. I realize your roof is superior to the standard shingles and was impressed with how they lock together to give a tight seal.
C O M M U N I C A T I O N. Our sales rep sold us and never called us again. Disappointing. He said he would be in touch with us. He lied. I became concerned and had to call the company. Never once did I receive a call about when the installation would happen. Never once did I receive a call thanking is for our very large purchase. Product is excellent. I am happy with my new roof.Installation guys were excellent. They deserve a bonus or a pat in the back.Financing gentleman was perfect.Sales guy and communication from Interlock not so good.Thanks kelly If your overloaded and can't make sure you are conveying gratitude then you need to hire someone who can make sure that happens.If you are hiring for sales and or Customer Service please call me.425-260-8512
