Interlock® Aluminum Roofing — all-climates performance specs for Mill 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

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 Mill Park
The following metal roofing FAQs are designed specifically for homeowners in Mill Park, 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 Mill Park.
Does a metal roof handle heavy snow and ice buildup in Mill Park winters?
Yes — aluminum's smooth, hard surface sheds snow and ice far better than asphalt, which traps moisture and promotes ice dams. Mill Park averages about 48 cm of snow annually and about 36 freeze-thaw days, conditions that accelerate asphalt wear. Interlock's four-way interlocking panels (ESR-1790 rated) create a unified surface that won't buckle or separate under thermal cycling, and optional snow guards let you control discharge safely without risking structural damage from accumulated loads.
Can an aluminum metal roof rust in Oregon's wet climate?
Aluminum cannot rust because it contains no iron — the chemistry is simply different from steel. What forms instead is an aluminum oxide layer that self-heals when scratched, so even exposure to Mill Park's 1,468 mm of annual rainfall won't trigger corrosion. The Alunar 70% PVDF fluorocarbon finish (warranted 30 years against chalking) bonds to both sides of every panel, adding a sacrificial barrier that keeps the underlying metal pristine for decades.
Will my homeowner's insurance cover hail damage to a metal roof?
Metal roofs often qualify for insurance discounts because of their superior impact resistance. Interlock panels carry a UL 2218 Class 4 rating — the highest available — and the warranty even covers perforation from hailstones up to 1.5 inches. Contact your agent with the UL 2218 and ESR-1790 documentation; many insurers recognize this performance and lower your premium, offsetting installation cost faster than you'd expect in a climate where hail risk is real.
Will a metal roof stay secure during Oregon wind storms?
Mill Park experiences typical gusts around 116 km/h; Interlock panels are warranted to resist wind speeds up to 120 mph (193 km/h) when installed to specification. The four-way interlocking design locks adjacent panels together at all edges, distributing wind load across the entire roof plane rather than relying on fasteners alone. This geometry, combined with proper fastening into the deck and underlayment, means no billowing, no panel separation, and no premature failures during the region's windiest seasons.
How does metal roofing handle Mill Park's heavy annual rainfall?
Solid standing-seam and shake profiles channel water downslope; the interlocking seams create multiple shingle-like barriers that defeat water backing up. With 1,468 mm of annual rainfall, Mill Park demands roofs that drain fast and shed water positively — asphalt absorbs and holds moisture, accelerating decay. Aluminum's hard surface and mechanical interlocks (ESR-1790 rated for IBC/IRC compliance) ensure water moves off your roof, not into it, protecting the deck and attic for decades.
Do I need to reinforce my roof frame for a metal roof?
No — aluminum's lightness is a structural advantage. The Mediterranean Tile profile installs at about 0.59 lb/sq ft, roughly 96% lighter than concrete or clay tile, so most existing roof structures require zero reinforcement. Mill Park's 48 cm average annual snowfall adds loading, but the aluminum assembly still weighs a fraction of slate or tile, meaning you avoid the engineering costs and construction delays that heavy materials demand. This also simplifies installation and reduces labor time.
How much maintenance does an aluminum metal roof need?
Essentially none compared to asphalt or wood. Asphalt requires roof repairs or replacement every 15–20 years; wood (cedar shake, shakes) splits, curls, and rots, demanding constant maintenance and chemical treatment. Aluminum doesn't rot, split, or curl — it just needs occasional guttering debris clearance, the same as any roof. The 30-year Alunar finish warranty (ASTM D4214/D2244 measured) means no re-coating, no re-painting, and no surprise failures tied to Mill Park's 2,957 annual sunshine hours of UV exposure.
Is a metal roof worth the upfront cost over asphalt in the long run?
The math is clear: asphalt lasts 15–20 years before replacement; Interlock carries a lifetime limited, non-prorated material warranty for the original owner, transferable to the next owner for 50 years from completion. Factor in asphalt tear-off/landfill costs, maintenance repairs during those 15–20 years, rising labor rates, and the Guardian Warranty's coverage against rusting, rotting, splitting, and curling, and metal becomes the last roof you buy. Current regional promotion: no payments and no interest until Spring 2027 or 10% off installation.
Does a metal roof improve fire safety for my home?
Aluminum is non-combustible — it cannot burn. Interlock offers Class A fire classification (the highest category under NFPA standards), meaning embers and flying brands cannot ignite the roof. Mill Park's dry season and occasional wind gusts (up to 116 km/h) can carry fire risk during summer months. An aluminum roof eliminates one pathway for wildfire loss, and the ICC-ES evaluation (ESR-1790, reissued 2025) confirms non-combustibility under both IBC and IRC testing protocols, protecting your home and potentially qualifying you for insurance advantages.
Is there a local installer in Mill Park who specializes in metal roofing?
Yes — Interlock Metal Roofing (PNW) Inc. has served the region since 1997 and understands the specific demands of Multnomah County's wet climate, wind patterns, and freeze-thaw cycles (about 36 per year). The company installs over existing roofs, minimizing disruption and disposal costs, and stands behind every installation with access to the Guardian Warranty and ESR-1790 compliance documentation. Local service means faster responses, familiarity with building permits, and accountability — not a national call center.
Is a metal roof a good choice for Mill Park’s climate?
Yes. Mill Park 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.
