- Precision weatherproof seams (profiles: slate, cedar, shake, tile) and mechanical fastening (profile: standing seam) deliver long-term leak protection during wind-driven rain events.
- Coated with the Alunar® Coating System (no visible aluminum surface) to minimize corrosion and preserve finish in Cascadia’s persistently damp conditions.
- Interlocking panel geometry resists uplift and has been tested to 193+ km/h (120+ mph), providing proven resistance to Linn County windstorm gusts.
- Designed for atmospheric river events that drive prolonged heavy rainfall through the South Santiam watershed and affect Cascadia properties.
- High snow-shedding performance and engineered load capacity reduce accumulation and help prevent ice-damming during inland freeze–thaw periods.
- Class A fire-rated available to improve protection for homes on forested parcels or wildland-urban interface zones in Linn County.
- Corrosion-resistant Alunar® finish also mitigates risk from occasional salt-laden air carried inland by strong coastal storms affecting low-elevation river corridors.
- Continuous interlock and standing-seam mechanical fastening limit thermal movement and seam stress across Cascadia’s rapid seasonal temperature swings.
- UL 2218 Class 4 impact resistance for hail, falling Douglas‑fir limbs, and other storm debris common to the region.
- Smooth, non-porous coated surface reduces moss and algae adhesion on damp roofs—critical for long-term performance on Cascadia homes.
- Reflective cool-roof characteristics lower absorbed heat during Pacific Northwest heat waves, improving attic comfort and energy performance.
- Lightweight aluminum lowers dead load on roof framing while delivering durable performance in saturated soil and valley-humidity conditions.
- Architectural profiles emulate slate, cedar shake and tile while engineered drainage paths and coated surfaces maintain wet-season reliability for Cascadia curb appeal.
- Standing-seam options support bracket-mounted photovoltaic systems without penetrating precision weatherproof seams, preserving leak protection.
- Backed by a transferable lifetime-limited warranty and documented field performance tailored to Cascadia and broader Linn County climate challenges.

Interlock® Aluminum Roofing — all-climates performance specs for Cascadia, 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:
From start to finish the folks at Interlock were amazing. After our home was damaged in last years wildfires in rural Oregon; we made the decision to replace the roof and siding in nonflammable materials. Our roof is beautiful. I’ve already had so many compliments on how great it looks and I’ll sleep better knowing my home is safe from exterior fire. The two workers were so polite and did an impeccable cleanup! I would highly recommend Interlock Industries.Sincerely, Sharon Shepard Positive: Responsiveness, Punctuality, Quality, Professionalism, Value Services: Attic venting, Roof installation

The guys that came here were very knowledgeable, and they did a great job.
Looks great, installers exceptional and peace of mind that I will not have to ever replace my roof again
The guy was professional and put on a good presentation.
None, they did very well. It is kind of to early to tell but I think they did a great job.
As stated above, the communication could’ve been greatly improved in the office. At the end of the project we asked for a can of touch up paint, I never heard back.
Scheduling Very good work well satisfied
My family is down for Mothers day and they all think it is nice. I'm glad that I do not have to do maintenance on it. I do not have to worry about anything, which is what drew me in. I still do not have my warranty. The men came on time and worked many hours a day.
The communication could improve. It took a little while for a return phone call from Interlock Roofing.
Don't sell a roof like a large-screen TV.
