Interlock® Aluminum Roofing — all-climates performance specs for Happy Valley, 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:
To the Interlock Corporation, What can you say about a home improvement experience such as replacing the roof on your house? From the first contact to the completion of the project, it was the most enjoyable experience a person can have when dealing with a large commercial company. From the initial non-high pressure, very informative sales contact from a Home and Garden show to the friendly, efficient and respectful installers to the final personal contact to ensure we were satisfied with the results and that we were enjoying our new roof. The application and quality of the materials are beyond expectations. We have been enjoying the roof through the winter winds and rain, and hail of the Pacific Northwest. Everyone asks if it is noisy and tinny when it rains. We reply, “of course not! “ It is even quieter than the comp roof we just replaced. We ordered the deep charcoal grey slate. After the rain, while still wet, the roof shines and glistens like real slate. It is a welcoming sight compared to the dull comp roofs of our neighbors. Shortly after installation, there was a wedding up the road from us. We heard from a friend who attended that our roof was the " data-wpil-keyword-link="linked">hot topic of discussion since everyone had to drive by our house to reach the wedding. We get many compliments from people who drive by. The installers, while being friendly, are very proud of their workmanship, and we liked the fact that they kept referring to the roof as “their roof”. Hard-working and diligent in the task, they were attentive to every detail. The best onsite reps Interlock could ever have. They were proud of the many years of service working for the company, and that fact, too, lends itself to efficient communication and workflow. The installation happened during the summer during some of the hottest days on record. The installers measured their days, coming early, resting during the hottest times and returning during the coolness of the evenings, doing what needed to be done to get the job done. While more expensive than traditional comp roofs up front, the fact that we never have to replace the roof during our lifetime is well worth it. This house is our forever house, and the best part of our new roof is the fact that my husband will never have to climb up a ladder to clean off the moss that grows so well here in the wet but green northwest. After much investigation and consideration of other metal roofing products on the market, we highly recommend a metal roof, specifically one by Interlock.
My wife and I chose the cedar shake look. It turned out very nicely. The crew took the time they needed to do the job right and explained the steps they were taking along the way. If you are looking for a high quality, long lasting, product that will impress, look no further. Services: Roof installation
Over eight years ago, I needed a new roof on my over 100 year old house and after significant research, decided to use Interlock Roofing. The installers arrived on time, were professional and completed the job as expected.A few months ago, my shop was in need of a new roof and I needed to do no research- I called Interlock, without hesitation. Working with Ross and Mike was very easy. I expected to have the work started sometime in the summer. But then I received a call that there was an unexpected break and that Interlock could start that day. I readily agreed, and the installers arrived by mid-morning. Once again the installers were polite, professional and were finished quickly. They cleaned up the site well. I am as happy today as I was years ago with Interlock. I have since added another project and am eagerly awaiting Interlock to complete it. I have no doubt that I will receive the same great product and professional installation.

We recently had our wood shake roof replaced with an Interlock metal roof that resembles the old wood shake roof. It looks fabulous and Victor and crew did a very professional job and removed all debris from the the old roof. We live among a lot of fir trees and with the ever present fire danger it is good to know we have the assurance that our roof is protected. We recommend Interlock Roofing to anyone looking at metal roofing and would be happy to show off our roof to anyone interested. Positive, Quality, Professionalism, Value, Services: Roof installation
Pine needles and more pine needles along with fir boughs each season covers our roof all throughout the year. We are consistently getting on the roof to blow off the needles and clean off the fir boughs. Though the job of cleaning off the roof does not take more than 3 – 4 hours, we were looking for a better way and an easier solution to our situation. Our neighbor was in the process of getting a new roof put on; it was Interlock Roofing Systems. We asked many questions regarding their roof and the options available. Their finished roof looked great. The metal roof in the slate shingles option looked really good. They were very pleased with their roof, the installers, and the installation process. Our sales representatives, Mike and Ross, explained the advantages of a metal roof, the benefits of Interlock Roofing and the installation process, answered all our questions and assured us that we’d be very pleased purchasing an Interlock Roof. Peter and Victor, our installers were personable, explaining their process. We had a couple of snow and ice days prior to our scheduled date, so they had to work hard to clean off and prepare the roof. They worked very diligently in the cold and some days in the heavy rain. Our roof took a few extra days waiting for additional materials to arrive. When it was all done, February 1, 2017, our Interlock Slate shingle roof looked great. We are pleased and are looking forward to years of our beautiful featured addition to our home.
We first learned about Interlock Roofing when researching roofing options on the internet. We became interested in a metal roof due to our constant problems with moss and fir needles. We went to the September 2015 Home and Garden Show to learn more. Interlock had a great display at the show, and the representative cleared up some questions we had. We scheduled an appointment, and within a week Ross and Mike came out and explained their product to us. They brought samples of the different styles and " data-wpil-keyword-link="linked">colors of their materials and thoroughly explained how their system worked. They even brought a collection of pictures from previous houses so we could decide the best look for our house. As they were measuring the roof, we watched a video on their company and all of the materials and guarantees they provide. We were impressed by their knowledge and experience. The installation only took about three days. Vladimir and Greg, our installers, were very friendly and worked diligently. They took the time to explain what they were going to do and how they were going to do it. Their craftsmanship really shows on the finished roof! We were extremely impressed when they were waiting on one piece of flashing to be in stock and Vladimir drove all the way from " title="Seattle" data-wpil-keyword-link="linked">Seattle to install the finishing piece. We can tell they take pride in the work. We ended up with a beautiful roof and several people have stopped to ask about our roof. We had received many compliments on how the style complements our home. Now that we have lived with it for a few months, we are not disappointed with our choice. It looks great, there is no moss, and the fir needles rinse off with the rain. It is quiet even in the worst rain storm and best of all, it will be the last roof that this house will ever need. We will likely save energy costs this summer and will greatly reduce, or eliminate altogether, ever having to go on the roof again. We highly recommend Interlock Roofing to anyone looking for a forever roof that looks great. All of the people that we dealt with were very knowledgeable and informative. They were easy to talk to and there was never a high-pressure sales pitch. We wouldn’t hesitate to recommend them or talk to anyone about our very good experience.
Our home was recently the lucky recipient of a new aluminum shingle roof by Interlock. We are sure that if our house could, it would be singing! So, my husband I and will gladly speak for it. We cannot say enough good things about the quality of our new roof material and installation. From the first visit with the sales team (thank you Mike and Ross) we were impressed with the professional and trustworthy service of Interlock representatives. The whole job took place right on schedule with lots of communication all along the way. The installation crew (thank you Peter!) was hard working, intent on making sure every detail was done to perfection, considerate of our landscaping and a pleasure to have on our property. The finished product: WOW! We love it! This new Interlock roof not only makes our farmhouse and garage look fabulous, in addition, we are so happy to know we will never scrape moss again, not to mention that we will probably never even replace our roof again! The color and style of the shingles are so pretty and we know our home is protected from the elements like never before. We won’t hesitate to recommend Interlock Roofing whenever we have an opportunity. This company has developed a product that really measures up to everything it advertises. Thank you, everyone at Interlock. We loved doing business with you!
We would like to thank Interlock Roofing for the excellent product and service we received when replacing our roof. We began work on our one-hundred-year-old house many years ago and thought that we had always hired competent contractors to complete work that we did not do ourselves. However, when replacing the original tongue and groove eaves last summer, we discovered that our seventeen-year-old composition roof was failing due to poor installation. A relatively small project became a much larger undertaking. Since we live in an area where we have a stand of trees behind us and considerable shade, moss has always been a concern. In an effort to avoid any more issues with a roof, I began researching various alternatives. Then I found Interlock Roofing! I learned more about roofing in a short amount of time than I had to talk with several other suppliers. All my questions were answered and my concerns were addressed. Communication between the sales department and the installation department was top-notch. The crew arrived when scheduled and completed the job in a timely manner. After we considered the job complete, we discovered a small problem. That, too was addressed quickly and without question. If we were to need another roof, we would hire Interlock Roofing again. But the excellent " data-wpil-keyword-link="linked">warranty makes that an improbability. We heartily recommend Interlock Roofing to anyone.
Ivan has worked on our roof multiple times. He is always responsive, communicative, efficient, and effective. We can recommend him and Interlock Roofing
Thank you Interlock Roofing for providing such a quality product and installation from which we will receive years of permanent protection from the elements. The job went smoothly. The crew showed up early and stayed late, answered all our questions, leaving a clean job site at the end of each day. The attention to detail was impressive. The house was a complex roof with skylights, vents and a masonry chimney. The quality and design of all the types of flashing’s, ridge vent, and fasteners were quite impressive and were expertly installed. The hardworking crew was attentive and stayed late when a rainstorm was expected to ensure we were watertight. This diligent crew was the best representative Interlock can have. From the initial contact at the Home and Garden Show in Portland to the visit from the Interlock Representatives to explain the product and show us the options, the experience was enjoyable and fun. One does not expect such friendliness when dealing with a larger company. We look forward to many years under our new roof.
The company was very informative and efficient, and we are happy with both the aesthetic and practical results. We are also happy to have a greater sense of security about the danger posed by fire, which has been a worry because we live in a forested area far from emergency services. The workers were polite and professional and cleaned up the site pretty well. It was expensive, but we're very satisfied with the work.

Metal Roofing FAQs for Homeowners in Happy Valley
The following metal roofing FAQs are designed specifically for homeowners in Happy Valley, 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 Happy Valley.
Will a metal roof handle Happy Valley's snow and ice buildup?
Yes—metal roofing actually sheds snow better than asphalt. Happy Valley averages about 48 cm of snow annually with roughly 36 freeze-thaw days per year, creating the exact conditions where ice dams form on traditional roofs. Interlock's four-way interlocking aluminum panels and smooth surface allow snow to slide off safely rather than trap moisture. The light weight—about 0.41 lb/sq ft for the Shingle profile—means no structural concerns even in heavy accumulation. Add snow guards if you want to manage runoff, but you won't deal with the ice-dam leaks that plague asphalt in freeze-thaw cycles.
Why won't an aluminum roof rust like steel roofing does?
Aluminum simply cannot rust because it contains no iron—iron is what oxidizes and causes rust. Instead, aluminum develops a natural oxide layer that actually protects the material underneath. When that layer is scratched, it self-heals. On top of that, Interlock applies Alunar 70% PVDF fluorocarbon coating to both sides of every panel, warranted 30 years against fading and chalking. In Happy Valley's 1468 mm annual rainfall, that two-layer protection (oxide plus PVDF) keeps your roof performing. Steel roofing requires constant vigilance; aluminum requires none.
Can a metal roof handle Happy Valley's wind gusts?
Absolutely. The region sees typical gusts up to 116 km/h, and Interlock's warranty covers wind resistance up to 120 mph (193 km/h) when installed to specification. The four-way interlocking panel design distributes wind load across the entire roof system rather than relying on fasteners alone. Each profile locks together on all four sides, creating a unified structure that flexes and holds. Happy Valley's wind environment is well within the performance envelope—you're not fighting against your roof's design, you're benefiting from it.
Does hail damage metal roofing, and will homeowners insurance care?
Interlock metal roofing carries a UL 2218 Class 4 impact rating—the highest available—and the warranty even covers perforation from hailstones up to 1.5 inches. Many insurers recognize this durability and offer premium discounts for impact-resistant roofing. Happy Valley's climate doesn't feature extreme hail frequency, but when it does occur, you have documented third-party proof (UL testing) that your roof won't fail. Unlike asphalt, which dents and loses granules in hail, aluminum panels survive intact. That resilience—backed by warranty coverage—often translates to measurable insurance savings.
Is metal roofing worth the upfront cost compared to asphalt?
Metal roofing costs more initially but is the last roof you'll buy. An asphalt roof lasts 15-25 years and then goes to the landfill; you repeat the tear-off, disposal, and installation cycle multiple times over a 50-year period. Interlock comes with a lifetime limited material warranty for the original owner—non-prorated—and transfers to the next owner for 50 years from completion. That means one installation covers decades without replacement. Factor in no rust repairs, minimal maintenance, potential energy savings, and possible insurance discounts. Over the life of your home, you're paying less per year while avoiding the labor and waste of multiple tear-offs. Right now, financing is available with no payments and no interest until Spring 2027, or 10% off installation.
What does Interlock's lifetime warranty actually cover?
The Guardian Warranty is a lifetime limited material warranty for the original owner covering rusting, rotting, splitting, cracking, curling, and loss of impact resistance—the failures that end other roofs early. Non-prorated means you're covered at the same level for decades, not watching coverage shrink each year. You can transfer it once to the next owner, who gets 50 years of coverage from the completion date. No rust (aluminum contains no iron), no wood decay (it's metal), no impact-related failure (UL 2218 Class 4). Happy Valley's 1468 mm rain and 36 freeze-thaw days per year are exactly the conditions that prematurely age asphalt and wood; aluminum and fluorocarbon coating laugh at both.
How much upkeep does a metal roof need in Happy Valley's climate?
Almost none. Asphalt requires annual inspections, moss/algae removal in wet climates, sealant reapplication, and granule monitoring. Wood shakes need fungicide treatments and regular replacement of split shingles. Interlock metal requires no painting, sealing, or chemical treatments. Debris (needles, leaves) rinses off during Happy Valley's frequent rainfall—about 1468 mm annually does the cleaning for you. The Alunar coating won't chalk or fade significantly over 30 years of service. Your job is to clear gutters and trim overhanging branches, same as any roof. The CALGreen sustainability certification acknowledges reduced maintenance as a measurable benefit. It's not no-maintenance, but it's fundamentally different from the constant upkeep asphalt demands.
Can a metal roof install over my existing asphalt roof?
Yes, and that saves time and money. The light weight is the key—Interlock Shingle installs at just 0.41 lb/sq ft, Tile at 0.59 lb/sq ft (about 96% lighter than concrete or clay tile), so no structural reinforcement is needed in most homes. Installation typically happens directly over the existing roof, which means no tear-off disposal, no weeks of exposed plywood, no dust in your home. Your local installer, Interlock Metal Roofing (PNW) Inc., has served the region since 1997 and knows Happy Valley's conditions. They follow ICC-ES evaluation report ESR-1790 (current through 2025) to ensure the installation meets code. The process is faster, cleaner, and quieter than a traditional re-roof.
What does metal roofing look like—does it have to look like a warehouse?
Interlock offers five profiles specifically designed to match traditional architectural styles: Slate, Cedar Shingle, Shake, Mediterranean Tile, and Standing Seam. Each one replicates the texture and shadow lines of its namesake material—Slate mimics layered stone, Cedar Shingle and Shake replicate hand-split wood grain, Tile matches curved clay profiles, and Standing Seam offers clean modern lines. All are manufactured from the same roofing-grade 3105-H24 / 3003-H24 aluminum alloy (ASTM B209) with Alunar fluorocarbon coating. Your home won't look industrial; it looks like the architectural style you choose, with the added benefit of zero rust, no wood rot, and 120 mph wind warranty. Happy Valley's mix of ranch and traditional homes shows all five profiles working beautifully.
Is metal roofing fire-safe for Oregon homes?
Class A fire classification is available for Interlock aluminum roofing—the highest fire-resistance rating. Aluminum is non-combustible by nature, so the roof itself won't ignite or spread flame. The ICC-ES evaluation report ESR-1790 documents compliance with IBC/IRC fire codes (reissued 2025). For homeowners in Oregon, especially in areas with wildfire risk or high-density neighborhoods, a non-combustible roof eliminates one major liability. Some insurers recognize Class A roofing with lower premiums for fire risk. Happy Valley's location in Clackamas County means you benefit from that protection without sacrificing curb appeal—you get it in whatever architectural style you choose.
