Interlock® Aluminum Roofing — all-climates performance specs for Helvetia, 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 saw the add on TV and knew a bit about Interlock Roofing and of course The “Never roof again”…. Slogan. Finally, we decided to contact them and make an appointment. Damon, our sales guy, was great and answer ALL of our questions. Finally, WE WENT FOR IT!!!!!! and WE LOVE IT!!!!! Positive: Quality, Professionalism, Value Services: Roof installation
I looked into replacing my roof and found that with modern composite shingles I will end end replacing it numerous times in my lifetime. With Interlock it's one and done. The roof I got was red aluminum in a slate style and it looks great; best roof in my neighborhood, hands down. Positive, Professionalism, Services: Roof installation
I thought Glenn was prepared with information, documantation, and answers. He was professuonal and exceptionally knowledgable.
Standing on the ground looking up at the roof - I'm asked if everything is satisfactory - I'm not sure I would know?! It looked GREAT! I'd suggest a follow up assessment and statement that someone has overseen the job and it's completed.
I can think of none on the overall project. Perhaps covering hedges with a tarp could have made it easier to clean up the metal scraps?
We thought they were excellent.
I realized, I needed to wait until next year to replace roof. Still interested in InterLock.
Project started late. There was some confusion over who was responsible for a transition to separate roof. The mailbox was a nice addition.
There was a mixup with the contact numbers. Initially, a date was set. It came and went. We had to get ahold of them. They had to let us know when the date was. It was just a little mix-up in communication.
I was initially apprehensive about the higher upfront cost of Interlock when compared to a basic composite shingle replacement, but three factors swayed me to give Interlock my business. First, the engineering behind the product is quite impressive.
Pre job communication can be improved, coordinator did not know where crews where at noon, were scheduled for me in morning. Not good, she was not helpful.
I already have.
