Interlock® Aluminum Roofing — all-climates performance specs for Alston, 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:
Other than a material delay due to an incorrect measurement, that was indeed handled quickly and well communicated, I can’t think of anything that would require improvement. Damon even answered my call while he was vacationing! The installation crew was quick, efficient and helpful when they suggested a better material for the bay window... very very happy with the whole experience!! We love our roof! It’s quiet even with all our rain and I love knowing we don’t fill up the landfill with the aged composite roof on our home! Best roof for us! Great company to work with! The off-season install was perfect.
Excellent service. I am happy that I have a great roof.
they were spot on will everything would recommend this company to anyone
We have had our interlock roof on for over 15 years. Still looks great no problems. We are glad that we don't have to worry about a roof anymore. They stand behind warranty.
Communication from office staff on installation date. Evidently my office person went on maternity leave and there was no one to back her up or to retrieve her phone messages or her email. Had to call our wonderful Sales rep to get any updates.
It was definitely worth it in the long run, I don't understand why everyone doesn't have one of these roofs for safety with the chance of fire in our area. The crew did a great job.
i had a good experance with inter lock they did a varry good job i do not know how they could improve. thank you keep doing a good job
As far as Michael's presentation, he did a nice job and was confident and informative.
Multiple people have complimented the roof and how quickly it was put on. I didn't pick the roof for the looks, I picked it for the functionality. The beauty of it is breathtaking.
Iven inspected and repaired , added calking under windows
The customer service is a little lacking. They could have improved their customer service for our project. The final product is great. The field team was great. I think they bit off more than they could chew with the housing boom and got overbooked. The roof is great, though!
Being on time with schedule would have been nice. Plus the communication was a total fail
