Interlock® Aluminum Roofing — all-climates performance specs for East Columbia, 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

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. Positive Responsiveness, Punctuality, Quality, Professionalism, Value ServicesRoof installation
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.

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.
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.
I had a "slate style" metal roof installed by Interlock Roofing and these guys are great! They were so polite and fast, they got my whole roof done in just two days and cleaned up the site perfectly. I would highly recommend them. Positive, Professionalism, Services: Roof installation

Metal Roofing FAQs for Homeowners in East Columbia
The following metal roofing FAQs are designed specifically for homeowners in East Columbia, Oregon. Whether you are building a new home or replacing an existing roof, understanding how roofing materials perform in local weather conditions is essential. From wind and storm protection to fire resistance, hail impact, snow loads, and coastal moisture exposure, Interlock’s Lifetime Aluminum Roofing System is engineered to provide long-term durability, energy efficiency, and peace of mind in East Columbia.
How does a metal roof handle East Columbia's snow and freeze-thaw cycles?
Metal roofs shed snow efficiently because the smooth, slippery surface and thermal properties prevent ice dams—a major advantage in your region's ~48 cm annual snowfall and 36 freeze-thaw days per year. Interlock's four-way interlocking aluminum panels are designed to the ICC-ES ESR-1790 standard and can be fitted with snow guards if you want to control snow shedding. The lightweight aluminum (Slate profile installs at just 0.41 lb/sq ft) means no structural concerns from accumulation, and the coating won't degrade through repeated freeze cycles the way asphalt shingles do.
Will heavy rain penetrate a metal roof?
No—four-way interlocking aluminum panels create a watertight system that handles your area's typical ~1468 mm annual rainfall without leaks when installed to spec. Each panel locks at four points to its neighbor, plus the standing seams and valleys are engineered to channel water downward without pooling. Many homeowners worry metal roofs leak, but that's a misconception rooted in poor installation; properly seated panels over an adequate underlayment and solid deck are as leak-proof as any roof system, and far more durable than asphalt once water eventually penetrates it.
Can aluminum metal roofing rust?
Aluminum cannot rust—it contains no iron, which is what rusts. Instead, aluminum develops a protective oxide layer that actually self-heals when scratched, so exposure to East Columbia's ~1468 mm of rain and variable humidity poses no corrosion threat. The Alunar® 70% PVDF fluorocarbon coating (applied to both sides and warranted 30 years) provides additional protection, so salt spray or airborne contaminants won't degrade the material. Steel roofing, by contrast, relies entirely on its coating to prevent rust; once the coating chips, oxidation begins.
Is a metal roof safe in East Columbia's wind and storms?
Yes—Interlock panels are warranted to resist wind speeds up to 120 mph when installed to spec, well above the ~116 km/h gusts typical in your area. The four-way interlocking system means each panel is locked to its neighbors on all sides, distributing wind load across the entire roof rather than relying on fasteners alone. The design is validated under IBC/IRC standards (ESR-1790), so local inspectors approve installations. In the 25+ years Interlock has served the PNW, this locking mechanism has proven itself in coastal storms and variable weather patterns.
Does hail damage a metal roof, and can it affect my insurance?
Interlock aluminum roofs carry a UL 2218 Class 4 impact rating—the highest available—and the warranty even covers hail perforation up to 1.5 inches. Because aluminum is so much harder than asphalt and doesn't crack or dent like traditional materials, insurers often view metal roofs favorably for hail-prone regions. Some carriers offer premium discounts on homes with metal roofing, though you'll want to check with yours. For East Columbia's occasional severe weather, the combination of impact resistance and non-prorated lifetime coverage under the Guardian Warranty means you're protected whether hail damage is minor or major.
Will a metal roof help with cooling costs in summer?
energy-efficient Interlock colors with initial solar reflectance up to 0.55 and thermal emissivity of 0.84 reflect heat that dark asphalt absorbs, reducing cooling load in warmer months. East Columbia averages ~2957 sunshine hours annually, so even though winters dominate, reflective coatings still lower summer air-conditioning demand. Cool Roof Rating Council verification confirms the thermal benefit. The payoff depends on your cooling usage, but over a 50-year roof life, the energy savings compound—especially compared to asphalt, which absorbs solar heat and accelerates breakdown.
What's the real lifespan of a metal roof, and what does the warranty cover?
Interlock's Guardian Warranty is a lifetime limited, non-prorated material warranty for the original owner—meaning no gradual reduction in coverage—covering rusting, rotting, splitting, cracking, curling, and loss of impact resistance. That single-owner term is transferable to the next owner for 50 years from completion, which gives prospective buyers confidence in your home's value. The roofing-grade 3105-H24 / 3003-H24 aluminum alloy (ASTM B209) and 30-year Alunar® coating warranty (ASTM D4214/D2244 tested) mean the roof will outlast multiple asphalt cycles, easily 50+ years with proper installation and maintenance.
Can I get a metal roof that looks like slate, cedar shake, or tile?
Yes—Interlock offers five profiles for this page: Slate, Cedar Shingle, Shake, Standing Seam, and Mediterranean Tile. Each replicates the visual character of its namesake material using the four-way interlocking aluminum panel system. The Tile profile, for example, achieves authentic Mediterranean or clay-tile aesthetics while weighing about 96% less than real tile, eliminating the need for structural reinforcement. You can choose the look that suits your home's architecture without the weight penalty, maintenance burden, or cost of traditional materials—each profile is ICC-ES certified (ESR-1790) and installs over most existing roofs.
How long does a metal roof installation take, and can you install over my old roof?
Installation timeline depends on roof size and complexity, typically ranging from a few days to a week. Most existing roofs—asphalt, wood shake, even composite—can accept Interlock panels because the aluminum is so light (Slate at 0.41 lb/sq ft, Shake at 0.58); no structural reinforcement is needed. Your local installer, Interlock Metal Roofing (PNW) Inc., has served the region since 1997 and can assess whether your deck and framing are sound. Installing over an existing roof saves tear-off labor and landfill costs; if removal is necessary, you'll discuss that upfront. Current financing (no payments or interest until Spring 2027) makes the timeline part of a longer affordability picture.
Is metal roofing environmentally better than asphalt shingles?
Aluminum roofing is approximately 95% recyclable and ends the 15-to-20-year cycle of asphalt tear-offs that fill landfills. Your aluminum roof will likely outlast 2–3 asphalt replacements over 50+ years, so fewer material cycles and fewer disposal trips overall. When the roof eventually reaches end-of-life, the aluminum goes to scrap recyclers, not a dump. Interlock's manufacturing in Delta, BC, and installation over existing roofs (avoiding tear-off) reduce transport and waste further. CALGreen verification confirms the maintenance reduction too—no sealant reapplication, no granule loss—so the environmental benefit extends to the resource use over the roof's operational life.
Is a metal roof a good choice for East Columbia’s climate?
Yes. East Columbia averages about 48 cm of snow, 1468 mm of rain, roughly 36 freeze–thaw days a year, with peak wind gusts near 116 km/h. Interlock® aluminum roofing is wind-rated to 193+ km/h (120 mph), UL 2218 Class 4 impact-rated and Class A fire-rated, and its four-way interlocking panels shed snow and resist ice dams and freeze–thaw cracking — all backed by a lifetime limited, transferable warranty.
