Interlock® Aluminum Roofing — all-climates performance specs for Piedmont, 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. 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 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.
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 Piedmont
The following metal roofing FAQs are designed specifically for homeowners in Piedmont, 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 Piedmont.
Does metal roofing handle snow and ice the way asphalt does in Piedmont winters?
Metal roofing sheds snow and ice more effectively than asphalt because the smooth, hard surface and thermal properties prevent ice dams from forming. Piedmont averages about 48 cm of snow yearly with roughly 36 freeze-thaw cycles, creating the exact conditions where ice dams trap water and cause leaks in traditional roofs. Interlock's four-way interlocking panels and light weight (the Shake profile at 0.58 lb/sq ft) eliminate structural strain from accumulated snow load, and the aluminum's natural tendency to allow snow to slide prevents dangerous overloading. Optional snow guards can be installed if roof-to-ground snow discharge is a concern for walkways or landscaping.
Why can't aluminum roofing rust, and does that matter in Oregon's wet climate?
Aluminum cannot rust because it contains no iron; instead, it forms a self-healing oxide layer when exposed to air. In Piedmont's 1468 mm annual rainfall and humid conditions, this is decisive: steel roofing corrodes from the inside out once fasteners or scratches expose bare metal, while Interlock's roofing-grade 3105-H24 and 3003-H24 aluminum alloy (ASTM B209) with dual-sided Alunar 70% PVDF coating (30-year warranty against corrosion) simply does not. The coating protects both sides of every panel, providing redundancy that asphalt and wood cannot match in high-moisture environments.
Can a metal roof handle Piedmont's wind gusts without leaking or lifting?
Yes—Interlock panels are warranted to resist sustained winds up to 120 mph and are rated for Piedmont's typical gusts near 116 km/h (72 mph) with a wide safety margin. The four-way interlocking system means each panel locks to its neighbors on all sides, distributing wind load across the entire roof rather than relying on fasteners alone. This design, verified under ICC-ES ESR-1790 (2025), prevents the gradual loosening and uplift that can occur with shingles in areas with regular wind events. Proper installation to specification is essential and is part of Interlock Metal Roofing (PNW) Inc.'s service standard.
What's the hail rating on metal roofing, and could it lower my insurance costs?
Interlock metal roofing holds UL 2218 Class 4 impact rating—the highest classification available—and the Guardian Warranty even covers perforation from hailstones up to 1.5 inches. This superior impact performance often qualifies homeowners for insurance discounts; contact your insurer with the UL 2218 Class 4 certification to ask. Piedmont experiences occasional severe weather, and a non-degradable roof that cannot crack, split, or lose impact resistance over time offers measurable peace of mind and potential premium savings that asphalt cannot match.
How long does metal roofing last, and what's actually covered by the warranty?
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—conditions that plague asphalt and wood in Piedmont's 1468 mm rain and 36 annual freeze-thaw cycles. It's one-time transferable, giving the next owner 50 years from completion, which significantly increases home resale appeal. No other roofing material offers this combination: permanent, unchanging performance backed by a 50-year transferable term means your roof is truly the last you'll buy.
Will a metal roof reduce my cooling costs in Piedmont's 2957 annual sunshine hours?
Interlock's energy-efficient colors with thermal emissivity of 0.84 and solar reflectance up to 0.55 reflect heat that asphalt absorbs, reducing attic temperature and cooling load during warmer months. With nearly 3000 hours of annual sunshine, even Piedmont's mild 11.5°C mean temperature benefits from reflective roofing—every degree of heat reflection in summer and shoulder seasons lowers air conditioning demand. Cool Roof Rating Council certification confirms measurable energy savings; combined with metal's zero thermal mass and no-degradation guarantee, your roof's reflectivity never decreases like asphalt.
Do I really have to maintain a metal roof less than asphalt or wood shakes?
Yes, significantly less. Asphalt requires regular inspection for granule loss and curling, especially with Piedmont's 36 freeze-thaw cycles; wood shakes rot and split in 1468 mm of annual rain. Interlock aluminum is CALGreen-verified for reduced maintenance—no algae growth, no splits, no rot, no granule debris clogging gutters. The Alunar 70% PVDF coating is warranted 30 years against chalking and fading (ASTM D4214), so even after decades, cleaning is optional cosmetic work, not structural necessity. A twice-yearly gutter inspection suffices.
Is metal roofing more expensive than asphalt when you count the full cost over time?
Metal roofing costs more upfront but ends the asphalt tear-off cycle that occurs every 15-20 years. Over a 50-year window, Piedmont homeowners typically replace asphalt 2-3 times, each time paying for removal, landfill fees, and new installation. Interlock's lifetime limited warranty and non-prorated coverage means no surprise replacements—you own the last roof you buy. Current financing (no payments or interest until Spring 2027, or 10% off installation) makes the entry cost manageable. When you factor disposal, labor, and replacement cost inflation, metal roofing is demonstrably cheaper over the asset's life.
Can my existing roof structure support metal roofing, or do I need costly reinforcement?
No structural reinforcement is needed for Interlock. The Cedar Shingle profile installs at 0.41 lb/sq ft, the Shake at 0.58, and the Mediterranean Tile at 0.59 lb/sq ft—about 96% lighter than concrete or clay tile—meaning your home's framing, already engineered for asphalt (which is heavier), handles metal roofing with ease. You can install directly over most existing roofs, saving weeks of decking work and thousands in labor. This is especially valuable in older Piedmont homes where structural upgrades would be prohibitive. Interlock Metal Roofing (PNW) Inc. assesses your roof structure at no cost during the consultation.
Is metal roofing actually more sustainable than asphalt, or just marketing?
Aluminum is about 95% recyclable at end of life, while asphalt roofing—torn off every 15-20 years—ends in landfills for decades. Over 50 years, that's 2-3 asphalt roof removals in Piedmont, each generating truck loads of waste. Interlock's one-time installation ends the cycle entirely. Aluminum itself is endlessly reusable without degradation, and the manufacturing process in Delta, BC, is energy-efficient compared to asphalt's petroleum and aggregate sourcing. Choosing a roof that lasts 50+ years and recycles cleanly is the measurable, quantifiable path to sustainability—not a one-time purchase claim.
Is a metal roof a good choice for Piedmont’s climate?
Yes. Piedmont 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.
