Interlock® Aluminum Roofing — all-climates performance specs for Madison South, 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. |

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

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.

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

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 Madison South
The following metal roofing FAQs are designed specifically for homeowners in Madison South, 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 Madison South.
How does a metal roof handle Madison South's snow and ice?
Interlock's four-way interlocking aluminum panels shed snow and ice efficiently while remaining securely fastened. With about 48 cm of snow annually and roughly 36 freeze-thaw cycles per year, your roof experiences real stress from thermal cycling and weight. The panels' light weight (Slate profile at 0.41 lb/sq ft) means no structural reinforcement is needed, and the smooth surfaces prevent dangerous ice dams. The 120 mph wind warranty ensures panels stay locked even when snow loads shift during thaws.
Will my metal roof leak in Portland's heavy rain?
Interlock's four-way interlocking seams create a continuous water barrier; panels nest together so rain cannot penetrate the joints. Madison South receives approximately 1468 mm of rainfall annually, making seal integrity critical. The interlocking design eliminates the reliance on sealants that degrade over time. When installed to ICC-ES ESR-1790 specification by a certified installer, the roof functions as a unified system. Proper underlayment and deck preparation complete the protection—no leaks occur when installation standards are met.
Does metal roofing qualify for hail damage insurance discounts?
Interlock aluminum roofing carries a UL 2218 Class 4 impact rating, the highest available, and is warranted against perforation from hailstones up to 1.5 inches. While Madison South's climate data doesn't indicate frequent hail events, this rating provides exceptional margin for severe weather. Aluminum's non-brittle nature prevents the cracking and shattering common in ceramic tiles or asphalt. Some insurance carriers offer premium discounts for Class 4-rated roofs. Check with your insurer about potential savings; the rating itself is documented and transferable should you sell.
Can aluminum metal roofing rust in a wet climate?
Aluminum cannot rust because it contains no iron—the element that oxidizes and corrodes. Instead, aluminum develops a thin, self-healing oxide layer that protects the metal beneath. In Madison South's 1468 mm annual rainfall, this is a decisive advantage over steel, which rusts rapidly when exposed. Interlock uses roofing-grade 3105-H24 and 3003-H24 aluminum (ASTM B209) with Alunar 70% PVDF coating applied to both sides, warranted 30 years against chalking. Even if the coating scratches, the aluminum itself remains corrosion-proof.
Will a metal roof reduce cooling costs in summer?
energy-efficient Interlock colors reflect significant solar heat—initial reflectance up to 0.55 and thermal emissivity of 0.84 mean less heat enters your home. Madison South receives approximately 2957 hours of sunshine per year; that reflectance compounds over time. While the region's mild mean temperature (11.5°C) limits summer cooling demand compared to hotter climates, every degree of reduced interior heat cuts air conditioning runtime. Cool Roof Rating Council ratings confirm the effect. Over a 50-year roof life, the energy savings add up, especially in years with warmer-than-average seasons.
Can a metal roof withstand Portland-area wind gusts?
Interlock's four-way interlocking aluminum panels are warranted to resist wind speeds up to 120 mph (193 km/h). Madison South experiences typical daily-max winds around 15 km/h, with gusts reaching 116 km/h—well within the warranty threshold. The interlocking design means each panel is mechanically locked to its neighbors; wind pressure cannot pry panels apart at the seams. This is distinct from overlapped shingles, where wind can lift edges. The system maintains its integrity across decades of the region's seasonal wind variation.
Do I need to reinforce my roof structure for metal shingles?
No structural reinforcement is required. Interlock's aluminum is extraordinarily light—the Slate profile installs at 0.41 lb/sq ft and the Mediterranean Tile at 0.59 lb/sq ft, about 96% lighter than concrete or clay tile. This lightweight advantage means the roof can install directly over most existing structures. Madison South homeowners can upgrade without foundation or framing work, reducing installation cost and complexity. The panels also install over existing asphalt roofing in many cases, eliminating expensive tear-off and disposal.
What warranty covers an Interlock metal roof?
The Guardian Warranty is a lifetime limited, non-prorated material warranty for the original owner, covering rusting, rotting, splitting, cracking, curling, and loss of impact resistance. It transfers once to the next owner for a 50-year term from completion. This means your roof is backed for life, and a future buyer receives documented protection. The Alunar coating itself carries a separate 30-year warranty against chalking and fading (ASTM D4214/D2244). Combined, these guarantees reflect confidence in the aluminum's durability and the manufacturer's commitment since 1998.
Can a metal roof look like slate, cedar shake, or tile?
Interlock offers five profiles: Slate, Cedar Shingle, Shake, Standing Seam, and Mediterranean Tile. Each replicates traditional material aesthetics in aluminum—Slate mimics natural stone, Cedar Shingle and Shake replicate wood grain and dimension, and Mediterranean Tile echoes clay. The profiles are manufactured to capture shadow lines and texture. Madison South homeowners can choose the architectural style that suits their home's character while gaining the durability of 3105-H24 aluminum and a 50-year transfer warranty. The aluminum substrate ensures the visual appeal lasts decades without the maintenance burden of actual slate, wood, or clay.
How much maintenance does a metal roof need compared to asphalt?
Interlock aluminum requires minimal maintenance—no annual inspections for missing or curling shingles, no moss or algae treatment, no sealant reapplication. Asphalt shingles typically require maintenance after 5-10 years and fail by year 15-20 in climates like Madison South's 1468 mm rainfall and 36 freeze-thaw cycles annually. Aluminum doesn't rot, split, curl, or crack under thermal stress. An occasional rinse removes debris; that is sufficient. The CALGreen-verified reduced-maintenance classification reflects this difference. Over a 50-year life, the time and cost savings are substantial compared to repeated asphalt replacement and repairs.
Is a metal roof a good choice for Madison South’s climate?
Yes. Madison South 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.
