Interlock® Aluminum Roofing — all-climates performance specs for Shaw, 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:
They could have improved the scheduling. We were scheduled almost a year out. We enjoy our roof but it took a long time. There were spots in the weather that would have been great to do the job but we missed those spots.
Just a Thank You to everyone in the company who helped to try and make things work. If we are in a position to add a metal roof somewhere down the line, InterLock will be our first choice
Jared form Interlock was great. Very detail oriented and thorough explaining all the types of roofing offered and providing us with a comprehensive estimate. If looking for a new roof. Dont hesitate, give them a call.
We are extremely pleased with the quality, appearance and fast installation of our new Interlock roof. The crew did awesome work and were friendly and careful. We feel so much safer with the protection of our metal roof on our home, which is surrounded by beautiful fir trees.
I am likely to recommend Interlock Roofing to a friend because it looks great. Interlock Roofing could have improved the notification of changes in timing, that would have been appreciated. We are really pleased with the way the roof looks, we've gotten a number of comments from neighbors about the attractiveness of the roof, and we're looking forward to years of good service.
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
Roof is great. Communication with customers!!!!!!
Update on my Interlock Roof System. I encourage you to read all of this review, because it has a very important element to it, and it might surprise you.I had the roof installed 2 years ago, & as noted in my original review below, the subcontractor at that time was less than attentive. Turns out, his crew was, too. In late 2020, there was a pretty significant leak into the kitchen from the sola tube, which prompted a repair call. The responses from customer service were a bit iffy, but Ivan (super knowledgeable guy) came out to inspect the leaks. At that time he also investigated the leaking behind the gutters & facia boards that had been happening right from the beginning. Apparently there was excessive condensation happening above and below the waterproofing, & it was a mystery why that was happening. It took two attempts to fix the leak into the kitchen, & a few more inspections to investigate the failing roof. There several visits and emails, & finally, in early 2021, I found it necessary to formally executed a warranty claim on the roof to HQ in Canada. I expected resistance.Here is the great part. Not only did Interlock Roofing take my warranty claim seriously, having Ivan come back yet again & open up a portion of the roof to inspect further; Mr. Yvon Giroux, VP of Installation in Canada, decided to have his best crew come out & completely tear off not only the Interlock Roof, but the asphalt roof underneath it as well, & start from absolute scratch. A fully new installation.To no one's surprise, they found mistakes were done by the first subcontracting crew (who didn't work for Interlock very long that year). I can tell you, the crew that came out last week were top notch. I haven't seen that amount of dedicated hard work in a very long time. It was obvious right from the start this crew was knowledgeable & well polished.I am so impressed with the Interlock Roofing System, the Company, and their integrity! The tear off, any repairs, & full installation was done in 2 days. Right after, we had several days of heavy rain. Not. One. Drip. Anywhere.The roof is even more attractive and beautiful than before. Interlock earned every one of their 5 stars. The roof is amazing, and I am one very satisfied customer.\*\*Original Review\*\*The roof is amazing. It looks great and the neighbors compliment it all the time. Big bonus is I have hardly used my air conditioning at all this year. What Interlock told me appears to be pretty spot on as far as the roof keeping the house cooler during hot weather. And finally, I really enjoy not having to get up on the roof several times a year to maintain it, knowing it is going to outlast me.The company was very gentle with us when we asked to postpone our fall scheduled installation for a few months due to a series of deaths, and as soon as weather permitted in the spring, we had the roof installed.The only thing that I was not thrilled about was when the installers arrived, I found out they were not employed by Interlock, as we were led to believe when we signed the contract last year. Quite honestly, had I known the installation was sub-contracted out, it would have been a deal breaker and I wouldn't have signed the contract. The sub-contractor was often busy with his other business needs and wasn't always on site during the installation. I understand his crew might only work on Interlock installations, but the owner of the contracting business was not solely dedicated to Interlock. He was a really nice guy, but not super attentive to my questions or concerns, which came back to haunt him later. I had requested a customer service follow-up after the installation that took a couple of months to have my concerned addressed fully.The reason for 4 stars instead of 5 was the sub-contractor instead of employees for the install, and the fact the customer service response was pretty slow. In the end, Interlock made good on everything. I still recommend them as a company, and I definitely recommend the roof. Services: Roof inspection, Roof installation, Roof repair
Looks great,unlike the common metal roofs you see.And being aluminum it won't rust out. Recently we had freezing rain which caused some tree limbs to break off and fall from a tree close to our house which demolished one gutter and part of another one,also partially smashing a roof vent ; but the metal roof held up supprisingly well. We also had a forest fire this past summer before putting this roof on that came close.A metal roof is just a little more deterent you can add against such events.5 stars. Damon,the installers,and everyone at interlock were wonderful and easy to work with. THANKS . Positive, Responsiveness, Punctuality, Quality, Professionalism, Value, Services: Roof installation

Metal Roofing FAQs for Homeowners in Shaw
The following metal roofing FAQs are designed specifically for homeowners in Shaw, 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 Shaw.
Why won't an aluminum metal roof rust in Shaw's rainy climate?
Aluminum contains no iron, so it cannot rust—period. Instead, it forms a thin oxide layer that actually protects the metal beneath and self-heals when scratched. Shaw gets about 1329 mm of rain annually plus freeze-thaw cycles that corrode steel roofing; aluminum stays intact through all of it. Interlock's 3105-H24 alloy is roofing-grade aluminum (ASTM B209) with a 30-year warranted Alunar fluorocarbon coating on both sides, giving you corrosion immunity where steel would deteriorate.
Does hail damage a metal roof, and can I get an insurance break?
Interlock metal roofing carries a UL 2218 Class 4 impact rating—the highest available—and the Guardian Warranty covers perforation from hailstones up to 1.5 inches. Shaw's wind gusts reach 111 km/h and hail does fall here; when it does, your aluminum roof shrugs it off. Many insurers recognize this durability and offer premium discounts. File a claim if needed—the warranty backs you. It's one reason metal roofing increasingly replaces asphalt in hail-prone regions.
Does a metal roof really lower cooling costs in Oregon summers?
Yes. Interlock's energy-efficient colors achieve thermal emissivity of 0.84 and solar reflectance up to 0.55, bouncing heat away instead of absorbing it like asphalt does. Shaw averages 3054 sunshine hours yearly and temperatures around 12°C mean; reflective metal roofing cuts cooling load during warm spells and works even better in direct sun. Over a 50-year roof life, that reflection compounds into measurable energy savings, especially if you run air conditioning during summer peaks.
Will a metal roof blow off in Shaw's wind?
No. Four-way interlocking aluminum panels are warranted to resist wind speeds up to 120 mph when installed to spec. Shaw's typical gusts hit 111 km/h (about 69 mph), well within that margin, and the interlocking design distributes load across the entire roof system. You get the security of metal's strength without the weight penalty—the Shingle profile weighs only 0.41 lb/sq ft, so wind has less surface to grab than with heavier materials.
How long does an Interlock metal roof actually last, and what does the warranty cover?
The Guardian Warranty is a lifetime limited, non-prorated material warranty for you as the original owner, covering rusting, rotting, splitting, cracking, curling, and loss of impact resistance. It transfers once to the next owner for 50 years from completion. At 1329 mm annual rainfall and 39 freeze-thaw days, Shaw's climate tests roofs hard; aluminum's oxide layer and PVDF coating resist both. You're looking at a permanent roof—no surprises, no prorating, no fine print excluding the problems that sink asphalt.
Can my house handle a metal roof, or do I need structural work?
Almost certainly not. Interlock's Mediterranean Tile profile—which mimics the look and weight of real tile—weighs just 0.59 lb/sq ft. That's roughly 96% lighter than concrete or clay tile. Most homes in Shaw can handle metal roofing over existing roof structure without reinforcement. A lightweight metal roof installs over most existing roofs, eliminating tear-off costs and reducing labor time. Your framing stays untouched because aluminum does what heavier materials can't: deliver durability without structural strain.
How long does a metal roof installation take, and can you install it over my old roof?
Installation typically takes days, not weeks—Interlock Metal Roofing (PNW) Inc. has been serving this region since 1997 and knows local conditions. Yes, the lightweight design installs directly over existing asphalt, so you skip the tear-off, dump fees, and labor cost. Shaw's 1329 mm annual rainfall and 27 cm of snow mean timing matters; your installer schedules around weather windows. Going over existing material saves weeks of exposure to the elements and cuts your total project cost significantly.
What maintenance does a metal roof need compared to asphalt or wood?
Virtually none. Metal doesn't degrade like asphalt (which curls and breaks down under UV), doesn't split or rot like wood shake, and doesn't require sealing, coating, or algae treatments. Shaw's 39 annual freeze-thaw cycles destroy asphalt shingles through expansion and contraction; aluminum flexes without cracking. CALGreen verification confirms reduced maintenance for Interlock metal roofing. Rinse gutters after storms. That's it. Your roof sits there and works for decades while asphalt roofs nearby are failing at 15 years.
Is a metal roof actually better for the environment than asphalt shingles?
Aluminum is roughly 95% recyclable at end of life—Interlock roofing manufactured since 1998 becomes material for future products instead of landfill waste. Shaw residents dealing with asphalt tear-offs produce thousands of pounds of landfill material; metal roofing ends that cycle. The product itself was made in Delta, BC, from recycled and virgin aluminum, and when your roof reaches the end—in 50+ years—it goes into the scrap stream as value, not garbage. One permanent roof beats four asphalt roofs in the landfill.
Is a metal roof worth the upfront cost over 50 years?
Yes. Asphalt roofs cost less initially but fail in 15–20 years; you replace it 2–3 times in a 50-year period. Metal roofs cost more upfront but last 50+ years with zero replacement. Factor in tear-off disposal, labor, reinstallation, and material inflation over decades—metal wins. Shaw's 1329 mm rain, 27 cm snow, and 39 freeze-thaw days accelerate asphalt failure; metal shrugs it off. Plus, current financing offers no payments and no interest until Spring 2027, or 10% off installation. This is the last roof you buy—the total cost of ownership favors metal by a wide margin.
Is a metal roof a good choice for Shaw’s climate?
Yes. Shaw averages about 27 cm of snow, 1329 mm of rain, roughly 39 freeze–thaw days a year, with peak wind gusts near 111 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.
