Interlock® Aluminum Roofing — all-climates performance specs for Johnson City, 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:
Thank you Interlock Roofing for providing such a quality product and installation from which we will receive years of permanent protection from the elements. The job went smoothly. The crew showed up early and stayed late, answered all our questions, leaving a clean job site at the end of each day. We look forward to many years under our new roof.
We were impressed over all, but at this price point and the number of other projects we need to do the roofing project needs to be put off for a number of years considering our roof is perfectly fine currently.
Ivan has worked on our roof multiple times. He is always responsive, communicative, efficient, and effective. We can recommend him and Interlock Roofing
It does look like a great product that they have. If I decide to buy a property and build I may look into calling them back.
We are still considering it, but probably not for another year or two.
Nothing Thank you for the peace of mind that Interlock roof system and lifetime warranty has given us.
Need two man crew all the time for safety.
My 1st time with the Interlock Roofing, I have no idea yet, but I think it's a good idea to have a project on spring or summer time. My kids said that my roof look pretty good
