Interlock® Aluminum Roofing — all-climates performance specs for Grant Park, 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 were so impressed with Interlock Roofing. The entire process was great from sales, to installation to clean up. They made the process easy even when we had a few curveballs for them. They worked with us wonderfully the entire time and our roof looks amazing. The installation team was so nice and respectful. Our roof is beautiful.
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
Love our new roof! Looks great and will last a lifetime. Install was fast, done in less than 2 days. The crew was courteous, professional and took the time to clean up the property before they left. Highly recommend.
We are very pleased with our new Aluminum roof, it looks great. The installing crew was topnotch! Very professional, friendly, on time daily, and cleaned the area daily as well. I will recommend Interlock to anyone who needs a new roof. Thank you Interlock!
INCREDIBLE experience from start to finish. From the moment we met with Damon and Mike, through the contract and purchase process, into scheduling and installation - we have had an amazing experience. The product and service are ABSOLUTELY worth the investment. We LOVE our new roof and give Interlocking Roof our highest recommendation.

I was amazed at the size of the roofing materials and their parts. Their roofing materials do “InterLock” to become a roof where water cannot find a way through it. The crew was very professional in their manner and expert in removing the old roofing material, then installing the new. They answered all my questions so I could completely understand their answers. The crew really impressed me by how quickly they completed the job.We had them replace some exposed beams in our alcove. The workmanship was great.The crew also did a great job of policing up our yard after they had finished the roofing. I recommend InterLock roofing to anyone who needs a new roof.

Positive: Professionalism, Punctuality, Quality, Responsiveness, Value Interlock gave us step by step on what to expect during the whole process of buying and installing our roof! Our energy bill is down, and the roof looks amazing! They fixed our back Desk, so there are no more leaks! The installers were fast and professional. They cleaned up everything before leaving at the end. I was very pleased with the whole process! Thank you, Interlock! Services: Roof installation, Attic venting
Our 18 year house needed something. A local roofer suggested a$ 5 K, roof treatment with yearly treatment of $1000. And a roof replacement with shingles at 60K. We looked into Interlock. I was impressed with the product and the absence of middlemen between installation. And quality if the product. The investment was significantly higher but we were impressed and felt it would be the best choice. The crew was polite and professional. They cleaned up every day as promised As you can see from the picture the roof is beautiful Positive: Professionalism, Punctuality, Quality, Responsiveness, Value Service: Roof installation
I absolutely love my new roof. Damon my sales rep was fantastic and the installers were the height of professionalism3/8/2021So after the snow and ice storm last month my metal roof still looks great and for the first time in 22 years I didn't have to worry about losing shingles in the storm.

Deciding to switch to an aluminum roof was a significant decision for us, and honestly, the selection process was a bit overwhelming. There are so many styles and finishes available, and it took us quite a while to finally make our choice. If you're considering aluminum, be prepared to invest time in understanding your options.The installation process itself also took longer than we initially anticipated, especially compared to the asphalt shingle replacements we've had done in the past. This is something to factor into your timeline if you're working with specific deadlines.However, despite the longer decision and installation periods, we are extremely pleased with the final result. The aluminum roof looks fantastic and has significantly improved the curb appeal of our home. It truly turned out nice.We were also impressed with the attention to detail shown by Interlock Metal Roofing. They used what appeared to be the correct mounting hardware, ensuring a secure and professional installation. Additionally, they didn't hesitate to replace any damaged or weakened boards as needed, which gave us peace of mind regarding the roof's long-term integrity.Overall, while the decision-making and installation processes were more involved than expected, the quality of the finished product and the professionalism of Interlock Metal Roofing made it a worthwhile investment. We would recommend them to others considering an aluminum roof, with the caveat that they should be prepared for a longer timeline.
Our new Interlock Roof is beautiful. And our neighbors have noticed. The whole process was very professional from beginning to finish. Victor, Daniel and Patrick were incredibly efficient, courteous, knowledgeable, and hard-working. Would recommend highly.
We are quite pleased with our new Interlock roof. It adds to the character of our house and looks great from any direction. Also, neighbors have extended their compliments. The experience, from start to finish was handled smoothly and professionally. When the project began, Art and Daniel worked hard, putting in long hours and cleaning the job site each day. Also, they were personable, responded to our questions, and accommodated a couple of requests as the job went along. In short, the roof looks great, and now that the fall rains have begun, we are especially pleased to have the job completed for the approaching winter. Nothing comes to mind. Nothing at this time.
