Interlock® Aluminum Roofing — all-climates performance specs for Oak Hills, 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:
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. Positive Responsiveness, Punctuality, Quality, Professionalism, Value
Fast response and excellent work. The technician drop by within couple of days, found the cause, and provided quote. The price was reasonable for the work scope. They were able to secure the work slot as soon as the raining season was over and kept me informed on the schedule. In addition, they inspected remaining roof as well. Note: the leak was due to gutter pulling the corner flashing. The 10+ year Interlock roof tile remained good.
Prompt, ongoing communication from bid to follow up after completion. Install crew was professional and polite. We had an involved tear-off and they spread tarps overnight in case of dew. Finished job looks great.
Roof looks amazing, install team was very professional kept the area very clean every day.
Interlock roof is the best. That is 12-15 years after we first got it. Perfect condition still! Never a second thought. Thanks
Interlock handled our roofing project with skill and expertise. Many other local roofers ran away from even bidding the job due to the complexity of our roof line. The result is exquisite and I'm hopeful any further service needed over the years will go just as smoothly as the install did. Positive, Quality, Value, Services: Roof installation
They installed an amazing IB membrane that makes the house look great. They suggested this product for my price range and expectations for a lifetime roof!
We had already decided on a metal roof when we came across Interlock. It was one of those things where we were looking for a product with a quality standard that could match up to what we wanted. I’ll say this, Interlock works a bit differently from most of the roofing people we talked to. You’re going to talk to a sales person at your home visit, but don’t let that put you off. They’re knowledgeable and if you haven’t done your research, there will be some great information in the whole thing that’s really worth soaking up. Anyway, we were satisfied with the quality of the product in hand and decided to go ahead and go with Interlock. The install was delayed by a week due to some shipping issues, but that was really the beginning and end of the troubles. The Interlock folks let me know what was going on and when they’d have it sorted. All fine by me. It’s a lifetime roof, I’m not too upset if it takes an extra week to put it on. As I understand it, mine was a bit of a one-off problem anyway. The roofers were professional, quick, and thorough. Great people who worked quickly, cleanly, and the cleanup at the end of the day was nigh on amazing. Apparently the shipping issues on my initial order led to the final install of a very few pieces being delayed a few days, but before I knew it they were back out and finishing the job. Along they way they kept me updated on anything I needed to know. The finished product is the real question, I guess. And man, let me tell you. We’re more than happy with how it looks on the house. It’s especially crazy knowing that something that looks that good is going to last. You see standing-seam metal roofs all over and even with these you sort of wonder how “metal” the Interlock system is going to look. It looks great. Seriously, even right in the driveway it’s hard to tell it’s not either a slate or colored shingle roof. It’s really beautiful and it’s going to be there without the need for constant maintenance for a long, long time. That really makes the cost worth it. If you’re thinking about a metal roof, give Interlock a serious thought. The sticker price might make you jump a little in some areas than others, but now that it’s on the house I am happy we decided to go that way. It’s beautiful, it’s going to last a good long time, and there’s a certain confidence I get from knowing I’ll be dealing with the people who make it if there’s a problem.
Our Interlock roof was the best home owner decision we have ever made.
We saw the add on TV and knew a bit about Interlock Roofing and of course The “Never roof again”…. Slogan.Finally, we decided to contact them and make an appointment. I recommend to do your work and check your roof, have ANY kind of questions or doubts that are particular to your case and be ready for your appointment.Damon, our sales guy, was great and answer ALL, and by that meaning ALL questions that we have, for example:How long it takes?How invasive construction will be?What about our skylights?What about vents?What will happen to gutters?How many people will be in my Home?Debris?Warranty of the product?Warranty and insurance?What if I sell my home, warranty?When will work start?…… WELL, and probably 20 more questions.I already helped you tons with this examples of question.Again, Damon was great and on point and also very HAPPY to be challenged by a well involved client (Us).Finally, WE WENT FOR IT !!!!!! and ………WE LOVE IT !!!!! LOVE IT ! LOVE IT!My deeply THANKS TO :MARK / TIM / VICTOR AND of course the wonderful PETER; these guys were our installers and we communicated well and they were FAST AND IMPECCABLE.Now, let’s consider the times that we are living in….There was some waiting, there were jobs ahead of ours, and everything depends on nature too, so considering All of that….. WE LOVE THE ROOF! The look! The fact that we WON’T reroof again.We hope this helps you on your decision to go with Interlock. Positive: Quality, Professionalism, Value Services: Roof installation
I looked into replacing my roof and found that with modern composite shingles I will end end replacing it numerous times in my lifetime. With Interlock it's one and done. The roof I got was red aluminum in a slate style and it looks great; best roof in my neighborhood, hands down. In fact it's fun to see cars driving by and notice the driver staring at the new roof. Also, I've received numerous compliments from passersby about how great the roof looks. Other points are that the install was quick and skillful and needless to say, I have no leaks. Positive, Professionalism, Services: Roof installation
I was initially apprehensive about the higher upfront cost of Interlock when compared to a basic composite shingle replacement, but three factors swayed me to give Interlock my business. First, the engineering behind the product is quite impressive. By that, I mean the way the panels interlock to form a tight, durable roof. Second, the roof looks great and will look the same for decades. Third, it’s a more environmentally sound solution by keeping my home cooler in the summer and also by being the last roof replacement the house will need. I have to say the installation crew was top-notch. They completed the job from tear-off to done in just over two days and left the gutters and yard cleaner than they found them. Admittedly my roof is small and fairly simple but to knock it out in two days during the triple-digit heat earned them my respect. All in all, I’d say I’m very happy with my new roof and the overall experience of working with Interlock.

Metal Roofing FAQs for Homeowners in Oak Hills
The following metal roofing FAQs are designed specifically for homeowners in Oak Hills, 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 Oak Hills.
Can a metal roof rust in Oregon's wet climate?
No. Interlock roofing uses roofing-grade 3105-H24 aluminum alloy, which contains no iron and cannot rust. Aluminum develops a self-healing oxide layer that actually protects the metal when scratched. Oak Hills receives about 1208 mm of rain annually, and the Alunar 70% PVDF fluorocarbon finish—applied to both sides of every panel—adds a 30-year warranty against corrosion, chalking, and fading. This dual-layer defense means your roof handles years of moisture without the degradation that affects steel or the rot that affects wood.
Does a metal roof hold up to hail in Oregon?
Yes. Interlock metal roofing carries a UL 2218 Class 4 impact rating, the highest available, and the warranty covers perforation from hailstones up to 1.5 inches. While Oak Hills averages only about 29 cm of snow yearly, severe weather systems can produce hail; the engineering that survives Class 4 testing also handles freeze-thaw cycles—around 37 days per year here—without cracking. Many homeowners qualify for insurance discounts; contact your carrier with the UL 2218 rating.
Will a metal roof blow off in Oregon wind?
No. The four-way interlocking aluminum panels are engineered to resist wind speeds up to 120 mph when installed to specification. Oak Hills experiences typical gusts around 120 km/h (75 mph), well within the rated capacity. The four-way interlock—unique to Interlock's design—distributes lateral force across multiple seams, and the lightweight profile (Slate at 0.41 lb/sq ft) means panels stay secure without the weight penalty of asphalt shingles or slate.
How does metal roofing handle heavy rainfall?
Metal roof panels are installed on a solid deck with an underlayment system, which means water moves directly to gutters and downspouts—the same principle that works for conventional roofs. Oak Hills receives approximately 1208 mm of rain yearly; the four-way interlocking seams prevent lateral water migration into the panel cavity. Proper installation by a certified local installer like Interlock Metal Roofing (PNW) Inc. ensures slopes and valleys shed water reliably, with no pooling or drainage issues unique to metal systems.
Do I need to reinforce my home's structure for a metal roof?
No reinforcement is needed. The Mediterranean Tile profile weighs about 0.59 lb/sq ft—roughly 96% lighter than concrete or clay tile—so it installs directly over most existing roofs without structural work. Even the heavier Shake profile (0.58 lb/sq ft) is negligible compared to traditional tile. This weight advantage means faster installation, lower labor costs, and the ability to re-roof without dismantling ceilings or walls. The ICC-ES evaluation report ESR-1790 confirms installation over existing structures in standard residential construction.
What is the warranty on 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. The warranty transfers once to the next owner with a 50-year coverage period from completion, which is significant during Oak Hills' about 37 freeze-thaw cycles annually—exactly the condition that stresses conventional roofing. Since Interlock has manufactured panels since 1998, real-world lifespan data confirms performance well beyond 50 years in coastal and extreme climates.
Will a metal roof reduce my cooling costs?
Energy-efficient Interlock colors are energy-efficient with thermal emissivity of 0.84 and initial solar reflectance up to 0.55 (Aged Copper Penny). Oak Hills receives about 3033 sunshine hours per year, making reflective coatings meaningful: lighter colors bounce heat away rather than absorbing it like asphalt shingles. The Cool Roof Rating Council has tested and rated these coatings. Summer cooling load reductions depend on your HVAC system and home orientation, but reflective finishes consistently lower roof surface temperatures compared to dark asphalt.
Is a metal roof fire-safe?
Yes. Aluminum is non-combustible, and Interlock offers Class A fire classification—the highest rating available. The ICC-ES evaluation ESR-1790 confirms compliance with IBC and IRC fire codes. Aluminum contains no wood or petroleum-based materials, so it won't ignite, spread flame, or release smoke the way asphalt or wood shakes do. If wildfire risk or local building codes specify fire performance, a Class A metal roof meets or exceeds every requirement without sacrificing style or durability.
Can I get a metal roof that looks like slate or cedar shake?
Yes. Interlock offers five profiles—Slate, Cedar Shingle, Shake, Standing Seam, and Mediterranean Tile—each designed to replicate traditional material textures in metal. The Slate and Cedar Shingle profiles match classic aesthetics; the Shake and Tile profiles deliver period-authentic appearance for heritage homes or contemporary designs. All profiles use the same underlying aluminum technology with four-way interlocking and the same Alunar 70% PVDF finish. Choose the profile that suits your home's character and Oak Hills neighborhood; the performance is identical.
