Interlock® Aluminum Roofing — all-climates performance specs for Cedar Mill, Oregon
| 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:
We had already decided on a metal roof when we came across Interlock. It was one of those things where we were looking for a product with a quality standard that could match up to what we wanted. The install was delayed by a week due to some shipping issues, but that was really the beginning and end of the troubles. The roofers were professional, quick, and thorough. The finished product is the real question, I guess. And man, let me tell you. We're more than happy with how it looks on the house.
They installed an amazing IB membrane that makes the house look great. They suggested this product for my price range and expectations for a lifetime roof!
Interlock handled our roofing project with skill and expertise. Many other local roofers ran away from even bidding the job due to the complexity of our roof line. The result is exquisite and I'm hopeful any further service needed over the years will go just as smoothly as the install did. Positive, Quality, Value, Services: Roof installation
Prompt, ongoing communication from bid to follow up after completion. Install crew was professional and polite. We had an involved tear-off and they spread tarps overnight in case of dew. Finished job looks great.
Just the communication for the install. A week later we have had some pretty hard rains. No leaks! and the roof looks great.
The crew did not have all the materials and had to make a trip to get the rest of the materials. Displeased with them not telling us they were going to cut a hole in our roof and left the attic full of sawdust.
I need more business cards! I think that your products are so great that I'd like to get the word out for you.
I would say that the communication pre-installation could have been a little better. we had to call. I am very happy.
Fast response and excellent work. The technician drop by within couple of days, found the cause, and provided quote. The price was reasonable for the work scope. They were able to secure the work slot as soon as the raining season was over and kept me informed on the schedule. In addition, they inspected remaining roof as well. Note: the leak was due to gutter pulling the corner flashing. The 10+ year Interlock roof tile remained good.
Nothing ...went smooth and was fast..done in 3 days.
Glenn did a great pitch. The price point i would need to make sense for this property is just lower than he could offer.
They told me that they would give me 2 signs and they didn't give them to me.
