Interlock® Aluminum Roofing — all-climates performance specs for Eastmont, 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:
I am totally pleased with my decision over 10 years ago to go with a 50 year Interlock Metal Roof! It has held up great to the test of time and when I am no longer on this mortal coil, my daughter, granddaughters or grandson will be benefitting from my decision!
There was miscommunication with Interlock itself. There was a start date that didn't happen. Materials were delivered but never taken off the truck. No one contacted me regarding that. I left a couple of messages and no one got back to me. We are really happy with the product.
That is the perfect roof because it is weather resistance, safe, and what can I say more? If I am going to live in this house forever, I would choose them.
did great
Our Interlock Roof has now been installed three weeks and we couldn't be more pleased. Suffice to say we haven't yet experienced the winds and rains of winter, but we are enjoying a much cooler home interior.
It went well.
Interlock staff does a lot of follow up over the phone, prior to, during and after installation. I wish there was an option to do follow up over email, website or even text messages.
The only step that was missing was notification of actual start date. Otherwise, the rest of the process was fine.
There was a small issue between the communication of the project manager and me. I was unaware of the timing of it. They said that it would be shipped soon and then it was there. We did not have anyone there to receive it. We were fortunate to have a neighbor. It looks really good.
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.
There were problems that were encountered during installation. see #14
