Interlock® Aluminum Roofing — all-climates performance specs for Jennings Lodge, 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:
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.
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.
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
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.
Company was very attentive to keep us updated on timing for installation. Weather was not cooperating and installation start was much longer than any of us anticipated but we received calls regularly letting us know they hadn't forgotten us. Once the installation was started it was finished in record time. Installers did a great job. We love our roof. It looks great.

Metal Roofing FAQs for Homeowners in Jennings Lodge
The following metal roofing FAQs are designed specifically for homeowners in Jennings Lodge, 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 Jennings Lodge.
Does a metal roof handle heavy snow and ice in Jennings Lodge?
Yes — aluminum's light weight and smooth interlocking profile actively prevent ice dam buildup that plagues asphalt roofs in your region's roughly 48 cm annual snowfall and 36 freeze-thaw days. Snow slides cleanly off without ponding on the valleys where ice forms. The four-way interlocking panels remain sealed even under freeze-thaw cycling, and you can add optional snow guards if you prefer gentler snow release. Unlike heavy slate or tile, which can crack under repeated freeze-thaw stress, aluminum expands and contracts uniformly without splitting.
Why can't an aluminum roof rust like a steel one?
Aluminum contains no iron — the element that rusts — so corrosion is chemically impossible. Instead, a protective oxide layer forms instantly when aluminum is exposed to air, and this layer self-heals when scratched or abraded. Jennings Lodge's 1468 mm annual rainfall won't accelerate rust because there's nothing to rust. Steel roofing, by contrast, requires constant paint maintenance to prevent iron oxide (rust) from spreading. Your Interlock panels arrive with Alunar 70% PVDF fluorocarbon coating on both sides, a 30-year protection against salt air and wet climates — double coverage because both faces see weather exposure.
Will my metal roof stay secure in Jennings Lodge's windstorms?
Completely secure — the four-way interlocking aluminum panels are warranted to resist wind speeds up to 120 mph, well above the typical gusts of 116 km/h recorded in your area. The interlocking geometry means each panel locks into its neighbors on all four sides, distributing wind load across the entire roof rather than relying on fasteners alone. Even in the strongest regional gusts, the panel edges and seams remain sealed. This design is why Interlock roofs survive coastal hurricane zones and Antarctic research stations — if it holds in those extremes, your Clackamas County weather is well within the safety margin.
Does a metal roof reduce cooling costs in summer?
Yes, if you choose an energy-efficient color with high solar reflectance — some formulations reflect up to 0.55 of incoming solar energy (measured as aged solar reflectance), meaning less heat enters your attic during the 2957 annual sunshine hours in your area. The thermal emissivity reaches 0.84, so the roof also radiates absorbed heat efficiently. Cool Roof Rating Council certification confirms these properties. Compared to dark asphalt, which absorbs most solar radiation, a reflective metal roof noticeably lowers attic temperature and your air-conditioning load on warm days. The energy savings compound over decades, offsetting the initial material cost.
Is my roof covered if hail damages it?
Your Interlock roof carries the highest impact rating available: UL 2218 Class 4, which means it survives 1.5-inch hailstones without perforation — a test few roofing materials pass. The Guardian warranty explicitly covers hail damage up to that threshold. Many insurers recognize this rating and offer premium discounts on homes with Class 4 metal roofs because hail claims are extraordinarily rare. Contact your agent with the UL 2218 Class 4 specification; some carriers reduce your premium immediately. Even in areas prone to severe hail, this rating has eliminated insurance disputes for Interlock customers.
Do I need to reinforce my roof frame for a metal roof?
No structural reinforcement needed — that's one of aluminum's largest advantages. Interlock Slate installs at roughly 0.41 lb/sq ft, and even the heavier Mediterranean Tile profile weighs only about 0.59 lb/sq ft, making it approximately 96% lighter than concrete or clay tile. Most existing roofs (whether framed for asphalt shingles, wood, or even old tile) can support this minimal load without modification. Your framing inspector will likely clear installation immediately. This lightweight design also means Interlock installs faster with fewer crews, reducing labor costs and installation timeline compared to traditional heavy materials.
How much maintenance does a metal roof actually need?
Minimal compared to asphalt, wood, or clay tile. There's no annual caulking, no re-sealing, no wood splitting or rot to monitor, and no granule loss. Jennings Lodge's 1468 mm annual rainfall and 36 freeze-thaw cycles will not degrade the aluminum or the 30-year Alunar coating. Twice-yearly gutter cleaning is prudent (standard for any roof), and you can hose off the panels if debris accumulates. The CALGreen program has verified Interlock's reduced-maintenance profile because the material simply doesn't fail like traditional roofs do. Over a 50-year lifespan, the time and cost savings vs. asphalt touch-ups, wood repairs, or tile re-cementing add up significantly.
What exactly does the warranty cover and for how long?
The Guardian Warranty is a lifetime limited, non-prorated material warranty for you as the original owner — it covers rusting, rotting, splitting, cracking, curling, and loss of impact resistance with no deductible and no time limit. The Alunar coating is separately warranted for 30 years against chalking and fading (ASTM standards). If you sell, the warranty becomes transferable: the next owner receives 50 years of coverage from the completion date, adding significant resale appeal. This structure reflects aluminum's true durability — manufacturers don't offer non-prorated lifetime warranties on materials that fail, and the coating outlasts most roof flashings and penetrations anyway.
Can you install a metal roof over my existing shingles?
Yes, in most cases — that's a major cost and timeline advantage. Interlock's light weight (roughly 0.41 to 0.59 lb/sq ft depending on profile) means it installs directly over existing asphalt, wood, or even old tile without tear-off or structural reinforcement. Your installer assesses the existing deck, adds underlayment and fasteners per ICC-ES ESR-1790 code, and the new roof goes on in days rather than weeks. No landfill disposal cost, no multi-day construction disruption, and your new roof is immediately weather-tight. Tear-off is only necessary if the deck is rotted or severely uneven — your local Interlock installer (PNW Inc., serving since 1997) will inspect and advise during the consultation.
Is a metal roof fire-resistant?
Yes — Interlock aluminum profiles are non-combustible and Class A fire-rated (the highest available). Aluminum contains no flammable materials and will not ignite, char, or contribute fuel to a wildfire. This matters in Oregon where regional fire risk drives insurance underwriting. Class A roofing is also a selling point for home buyers, and some insurers offer modestly lower premiums on non-combustible roofs. The ICC-ES evaluation report (ESR-1790, reissued 2025) documents this fire classification, so your local building department and insurer have the third-party proof they need. It's one of the few material advantages that protects both your home and your insurance costs.
