Interlock® Aluminum Roofing — all-climates performance specs for Sylvan-Highlands, 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 had a gorgeous Red Shingle Interlock roof installed and it had completely changed the look of our house! This roof was a long time coming…we placed the order in September 2021 and knew there was a 6mo wait but we were determined to wait it out and it was so worth it!The crew worked so fast and efficiently and really did a fantastic job. They were also super clean and made a great effort to leave no mess behind and even took care not to crush my plants.This is an expensive roof, make no bones about it, but the quality and durability as well as the beautiful look all are worth it.My house has had so many complements since it was done and compared to my neighbor next door who had a roof put on a couple months ago with traditional shingles, it is clear my roof is the favorite of the block!!

Interlock roofing is a fantastic company and the representative, Damon, was incredible. Always there to answer questions in a quick timely manner. I couldn’t be happier. This Aluminum roof will never need to be replaced and it makes my simple home look like a million dollar home. It’s stunning. I chose black slate and it is so beautiful. Such peace of mind too. I would highly recommend this company and its employees. The installation crew were professional and careful and accommodating. Thank You Damon and Interlock Roofing.

We had decided that we were ready to invest in a metal roof in our "forever home" for, among other reasons, its durability, eco-friendlly recyclable materials and light weight for seismic concerns. Damon was punctual and professional and an excellent salesperson. We had a very positive experience with May regarding scheduling; she was able to accommodate our timeframe and the crew showed up earlier than anticipated. The workmen were professional and very fast, and completed the tear-off and roof installation in 2.5 days. We were very impressed. The new roof is extremely attractive, and provided the whole house with the equivalent of a much needed "facelift!" We are delighted with our new roof and enjoy it every time we step away from the house to admire it. More thorough clean up, using magnetic tools to discover razors, nails and staples from tearoff. Better, more complete tarping to catch debris, not only on the slant side of the roof, but also the gable sides that are not slanted. They were not tarped, and that is where most of the debris and nails were found. An assessment for lead paint BEFORE working, which was promised, but not done. A smaller Interlock sign, in less garish (ie not fluorescent) colors, to display that would be acceptable for Washington County and the laws of other areas. I am not sure if the cardboard, water bottles and metal was separated and recycled off site, because it was all tossed into the same dumpster, but I would hope that since Interlock prides itself on eco-friendly recyclable materials, that it would follow through with recycling paper and metal as well. Roof, material, workmanship: 5 stars, Areas for improvement: Testing for lead pre-install, Tarping for Debris catch and Cleanup: Improvement needed, Communication re: Cleanup: Improvement needed, Information re: payment (cash, no credit card, upon completion): Improvement needed
We are very pleased with our new Interlock roof. While our house is nearly 100 years old, the new roof fits perfectly with the style and enhances the look of our home. We began receiving compliments from our neighbors almost immediately. Michael Laduke and his crew were professional and courteous, keeping the surrounding yard clean of debris and closing the gates each day to prevent our dog from escaping. Although the crew was slightly delayed due to an unfortunate encounter with a deer on the road, the work was completed just before the Thanksgiving holiday, adding the health and well-being of the crew and the beauty and protection of a new roof to our list of things to be thankful for. We greatly appreciate Mr. Laduke’s commitment to detail and his personal assurance that the project was completed before the holiday weekend. We would most certainly recommend Interlock Roofing Systems to anyone considering roof replacement.
Interlock Roofing installed an excellent metal roof on our house. It looks amazing and will last for years! The installer, Victor, was very professional and did a great job. He explained the work being done and even replaced a worn board on the garage. This product is definitely worth every penny!

Beautiful roof, replaced 44-year-old concrete tile. Installers showed up when scheduled, were conscientious and knowledgeable. They were hardworking, even in difficult cold weather.

Interlock Roofing installed a metal roof on our family home and it looks amazing. It has held up to extremely high rainfall so far. The crew that installed my roof was very professional and polite. I would recommend Interlock Roofing if you are in the market for a new roof.PositiveResponsiveness, Punctuality, Quality, Professionalism
It has now been nearly six months since our Interlock roof installation, and we couldn't be happier with it. We debated getting a metal roof due to the greater upfront costs relative to a standard composite roof, but we're not planning on going anywhere anytime soon, so the peace-of-mind of a lifetime roof -- knowing we won't have to do this again, and that the company stands behind the product the way they do -- makes it worthwhile. The installation crew was professional, and their customer service has been responsive when needed. Neighbors have commented too on how good our roof looks! Recommended! Positive Responsiveness, Quality, Professionalism Services Roof installation
At the recommendation of a neighbor, we chose Interlock Roofing and we couldn’t be happier. We’ve been homeowners for 40+ years and fortunately have never had to worry about a roof, as our houses were new, and we moved somewhat frequently. Then two years ago we bought a second home on the Oregon Coast and knew we would have to replace the roof within a few years. Until finding out about Interlock, I fretted about having it replaced. So, after having our second home’s roof replaced, I asked Damon to inspect our main, 16-year old house in Portland. He thought it had anywhere from 2 to 5 years life in it, but we opted to have it replaced for three reasons. First, why wait for a leak, second, because the warranty is going to outlive me and finally…it will never be cheaper. The roof is absolutely beautiful and is the envy of the neighborhood. Dealing with Interlock has been such a pleasure on ALL fronts. The communication throughout the process was flawless. They did everything and more that was promised. Very few products and services have ever impressed me more. ">" alt="Interlock Aluminum Shake Roof - Portland, Oregon USA" width="1500" height="1124" />
We are thrilled with the quality and look of the roof! The installers are true craftsmen of their trade and were so polite and courteous. Nothing negative to say. The sales rep that came to our home was sure a top notch sales rep for your company. Mike Rasmussen was very impressive with his knowledge and ability to make you understand. We had four estimates prior to Interlock roofing and had pretty much made a decision prior to Mike coming to our home. I was going to cancel the appoitment with Mike but felt it would be rude to do so on the same day so we kept the appoitment. So glad we did !!! Mike did an amazing job at showing all the advantages of Interlock roofing compared to ordinary roofing. Best decision we could have made for our home and ourselves! Now comes the only part we were not pleased with and feel you could greatly improve. We were promised a start date of absolutely no later then Sept. 14th. No materials had been delivered or no communication from Interlock had occured and it was Sept. 12th. I made a phone call and was informed the roofing material had not been delivered yet and the new start date would be Sept. 21st. Why we had not been kept in the loop on that I am not sure. The morning of the 21st I receive a phone call from Roland Stark saying an employee called in sick and they would be starting the next day on Tuesday the 22nd. Tuesday the 22nd I receive a phone call from Roland Stark that the employee called in sick again and they will begin the next day Wed. the 23rd. I questioned why you could not begin the tear off without him and was told he was the lead guy. During the sales process we were informed that all of your installers have been with you for many years. I believe Mike said at least 14 years. But I could be wrong on that. Maybe he said 13 years. I was confused why tear off could not begin with that kind of experience. Roland said at the latest they would start Friday and his crew promised they would work Sat. and Sunday both to complete the job. We were promised job completion Sunday the 27th at the latest. Sat. the 26th is the actual day the men showed up to begin on the roof. The men showed up prompt and begun work immediately. Very professional and hard working. I was impressed. As they wrapped up for the evening to leave I said, " See you tomorrow." They looked a little confused and replied, " We will be back on Monday as we have worked all week and are going home to see our wives and kids." Completely understandable except Roland told us they had been home sick all week. Official finish date was Sept. 30th. Roland needs to be more honest and upfront about the scheduling. It was very frustrating and was the only negative thing about the whole experience. We had Leaf Filter gutters and also Lifetime Exteriors(new siding) both scheduled to begin work the day following the roof project. Each time Roland promised a new date these two businesses had to be contacted and they would re-schedule their crews. Very frustrating for both us and them.You requested where Interlock could have improved, therefore I gave you an honest answer. But I am keeping that between your company and us. The negative scheduling part that is. When asked how we like our new roof we respond with," Best decision we ever made for our home. We love it and could not be happier!!!! If we had it to do over again we would certainly choose Interlock Roofing." Have NO REGRETS. LOVE the roof.
We’ve had our roof for about 7 years and have been very pleased with it. Recently, I scheduled gutter cleaning which was complicated by a run of wet weather which makes the roof very slippery. The gutter contractor asked if we had ever considered installing safety anchors. I didn’t know there was such a thing. I called Interlock and Ivan came by to take a look. He quickly determined appropriate locations for the anchors that the gutter cleaners could clip their safety harnesses to and showed me an example of the anchor itself. He also offered to paint them black to make them more inconspicuous on our dark roof. He returned about a week later for the install and afterwards showed us pictures of the anchors from the roof and pointed them out from the ground. Overall very professional, prompt, excellent service.
We love our roof! Interlock was wonderful to work with. Very knowledgable and helpful throughout the whole process. The team that installed were amazing and did amazing work. They cleaned up everything in a timely manner. One feedback I would have is giving more updates on when the project was slated to be started, originally was schedule during our vacation and we didn't know til a few days before we left. Overall we are very please and cant wait to never change our roof again!

Metal Roofing FAQs for Homeowners in Sylvan-Highlands
The following metal roofing FAQs are designed specifically for homeowners in Sylvan-Highlands, 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 Sylvan-Highlands.
How does a metal roof handle heavy snow in Sylvan-Highlands winters?
Metal roofs shed snow and ice far more effectively than asphalt because the smooth, hard surface resists ice adhesion—critical when your area averages about 48 cm of snow annually and experiences roughly 36 freeze-thaw cycles per year. Interlock's four-way interlocking aluminum panels stay flat under snow load without the buckling or warping that composite shingles develop. Snow guards can be installed where you need them. The lightweight construction—the Shake profile weighs just 0.58 lb/sq ft—means no risk of overloading your framing during heavy accumulation, and installation over your existing roof is straightforward.
Will a metal roof leak in Sylvan-Highlands' heavy rainfall?
No—the interlocking seams are engineered to shed water, not trap it. Your region receives about 1468 mm of rain per year, so leak resistance is serious business. The four-way interlocking design forces water down and outward; paired with proper deck preparation and underlayment during installation, panels remain watertight even in sustained downpours. The aluminum itself cannot rust or rot, so corrosion won't compromise the sealant or fasteners over time like it does with steel roofs or degrading asphalt. Interlock Metal Roofing (PNW) Inc. has been installing these systems locally since 1997 and understands the drainage demands of the Willamette Valley.
Can a metal roof survive Sylvan-Highlands wind gusts?
Yes—the warranty covers wind speeds up to 120 mph (193 km/h) when installed to specification, and your region's typical gusts average around 116 km/h. The four-way interlocking panels grip each other mechanically; they don't rely on adhesive or shingles that lift at the edges. Unlike asphalt, which becomes brittle and lifts in cold and wind, aluminum stays flexible. Proper fastening by a qualified installer like Interlock Metal Roofing (PNW) Inc. ensures the system performs as rated. Homeowners in high-wind zones often report peace of mind from metal simply because wind damage—the leading cause of insurance claims on asphalt roofs—doesn't happen.
Does my house need structural work to support a metal roof?
Almost certainly not. The Mediterranean Tile profile, despite looking like traditional clay, weighs only about 0.59 lb/sq ft—roughly 96% lighter than concrete or tile—so your existing framing carries it without reinforcement. Even the heavier Shake at 0.58 lb/sq ft is negligible compared to the 500+ lb/sq ft of real tile or slate. Most homes can have metal installed directly over existing asphalt or wood, saving the cost and mess of tear-off. The structural engineer's report (ICC-ES ESR-1790) confirms suitability on standard residential framing. This matters in Sylvan-Highlands: you avoid expensive foundation or beam work and can often keep installation to days rather than weeks.
Will hail damage a metal roof, and can I get an insurance discount?
Interlock panels carry the highest impact rating available—UL 2218 Class 4—and the warranty covers perforation from hailstones up to 1.5 inches. Aluminum's strength-to-weight ratio means it resists denting better than you'd expect; small dimples rarely occur and don't compromise the roof. More importantly, because metal roofs have a 50-year track record of resisting impact in hail regions, many insurers offer discounts on metal—sometimes 15-30% depending on your carrier. In Sylvan-Highlands, with its 11.5°C mean and mix of freeze-thaw events, the non-combustible aluminum construction (Class A fire rating available) can also reduce premiums. Contact your agent: a metal upgrade often pays for itself in lower premiums alone.
Is a metal roof worth the upfront cost compared to asphalt shingles?
Over the life of your home, metal is almost always cheaper. Asphalt roofs need replacement every 15-20 years; you'll buy three or four roofs in fifty years. Interlock's Guardian warranty is lifetime limited for the original owner—non-prorated, covering rusting, rotting, cracking, curling, and loss of impact resistance—and transfers to the next owner for 50 years. That means one roof, not four. There's no stripping old shingles to a landfill every two decades. Factoring in maintenance (metal requires almost none), energy savings from reflective coatings (up to 0.55 solar reflectance, energy-efficient), and avoided repairs, the total cost per year drops well below asphalt. Current financing—no payments and no interest until Spring 2027 or 10% off—also narrows the gap.
How much maintenance does a metal roof need?
Virtually none. Unlike asphalt, which degrades in UV and cold, metal doesn't chalk, split, curl, or lose granules. Unlike wood shake, it doesn't rot or require sealing every few years. Unlike tile, it won't crack in freeze-thaw cycles—and Sylvan-Highlands endures roughly 36 of those annually. Your main task: keep gutters clear and inspect flashing after severe storms, which you'd do anyway. The Alunar coating, warranted 30 years against fading, resists the 2957 annual sunshine hours without chalking. That low-maintenance design is why Interlock qualifies as CALGreen-verified for reduced maintenance. Asphalt demands moss removal, gutter flushing, and patching; metal asks almost nothing in return.
How long does installation take and can you install over my existing roof?
Installation typically takes 2-5 days depending on roof size and complexity—far faster than tear-off, sheathing replacement, and nail-down work. Interlock Metal Roofing (PNW) Inc. installs directly over existing asphalt or wood in most cases, eliminating the landfill waste and labor costs of removal. The lightweight aluminum—the Shingle at just 0.41 lb/sq ft—means crews work safely without overloading the structure even in wet weather common to Sylvan-Highlands' 1468 mm annual rainfall. A solid deck and proper underlayment ensure water sheds cleanly. The process is cleaner, faster, and less disruptive than traditional roofing—your driveway stays passable and your home stays functional while the work happens.
Do metal roofs really save on cooling costs?
Yes, if you choose an energy-efficient color. Interlock offers profiles with thermal emissivity up to 0.84 and initial solar reflectance up to 0.55 (Aged Copper Penny), which means the roof reflects heat that asphalt absorbs and re-radiates into the house. Even in a cool climate like Sylvan-Highlands (mean 11.5°C), this matters on 2957 annual sunshine hours and during the brief, intense summer weeks. Metal roofs also don't degrade in UV the way asphalt does, so their reflectance stays consistent for decades—no darkening that increases cooling load. The Cool Roof Rating Council rating confirms the thermal benefit. Over a 30-year roof life, the energy savings compound; pair it with current financing (10% off or no interest until Spring 2027) and the payback window narrows further.
Is a metal roof better for the environment than asphalt?
Yes—Interlock's aluminum is approximately 95% recyclable, and unlike asphalt shingles torn off and dumped into landfills, the panels stay in service for 50+ years. When they finally reach end-of-life, the aluminum scrap market ensures they're melted and reused indefinitely without degradation. No granule shedding pollutes gutters or stormwater. No tar or volatile compounds off-gas into your home or the air. By eliminating the tear-off-and-replace cycle that asphalt demands every 15-20 years, a single Interlock roof keeps multiple tons of composite debris from landfills over your lifetime. Sylvan-Highlands residents concerned about waste will find metal the honest choice: one roof, recycled end-of-life, zero toxic residue.
Is a metal roof a good choice for Sylvan-Highlands’s climate?
Yes. Sylvan-Highlands 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.
