Review: August 15, 2022Completion: June 30, 2022

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.

Review: May 5, 2021Completion: April 14, 2021

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

Review: November 26, 2018Completion: November 26, 2018

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!

Review: July 15, 2021Completion: October 19, 2020

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!

Review: September 15, 2020

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" />

Review: October 16, 2015Completion: September 29, 2015

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.

Review: April 20, 2026Completion: June 20, 2019

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.

Review: May 8, 2025Completion: April 17, 2025

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 Kerns

The following metal roofing FAQs are designed specifically for homeowners in Kerns, 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 Kerns.

Does metal roofing handle Kerns' snow load and ice dams?

Yes—metal's smooth, slippery surface naturally sheds snow better than asphalt, and the four-way interlocking panels resist ice dam formation. Kerns averages about 48 cm of snow annually with roughly 36 freeze-thaw cycles per year, creating exactly the conditions where asphalt roofs trap moisture and degrade. Aluminum expands and contracts minimally, maintaining panel-to-panel seals through repeated thaw-refreeze. Snow guards are available if you prefer controlled snow release. The light weight—about 0.41 lb/sq ft for the Shingle profile—means no structural reinforcement, even under peak snow load.

With 1468 mm of rain a year, will a metal roof leak?

The four-way interlocking design creates overlapping seams that shed water before it reaches the deck, and the panels can be installed over your existing roof, adding an extra moisture barrier. Kerns receives approximately 1468 mm of rain annually, and Interlock panels are rated under ICC-ES evaluation ESR-1790 for full water resistance. The standing-seam profile offers the tightest overlap if maximum leak protection is your priority. A solid deck plus underlayment under any profile performs like asphalt in heavy rain—completely silent and completely dry.

Can aluminum metal roofing rust in a wet Pacific Northwest climate?

Aluminum cannot rust because it contains no iron. When exposed to moisture, aluminum develops a thin oxide layer that actually protects the metal underneath and self-heals when scratched. The Alunar 70% PVDF fluorocarbon finish is applied to both sides of every panel, adding 30 years of warranty coverage against chalking and fading. This dual-coat approach is especially valuable in Kerns' 1468 mm annual rainfall, where wet conditions accelerate corrosion of steel-based alternatives. The result: a roof engineered for coastal salt-air homes performs equally well inland.

Are metal roofs safe in Kerns' windstorms?

Yes. The four-way interlocking panels lock together to create a unified system warranted to resist winds up to 120 mph (193 km/h). Kerns sees typical gusts around 116 km/h, so your roof will handle regional storms with margin to spare. Unlike shingles that lift and tear, interlocking panels distribute wind load across the entire roof plane. Installation must follow Interlock's specifications to activate the warranty, and our local installer, Interlock Metal Roofing (PNW) Inc., has served this region since 1997 and knows the wind patterns here.

Will my house's frame need reinforcement for a metal roof?

No structural reinforcement is needed. The Interlock Slate profile weighs about 0.41 lb/sq ft—roughly the same as asphalt shingles—while the Mediterranean Tile profile, despite its visual weight, tips the scales at approximately 0.59 lb/sq ft and is about 96% lighter than real concrete or clay tile. This allows installation directly over most existing roofs without rework. Your framing can already support it. The weight savings also mean faster installation and lower labor costs compared to traditional tile, while you keep the visual appeal of premium materials.

Do Interlock metal roofs reduce cooling costs in summer?

energy-efficient colors reflect up to 0.55 of incoming solar radiation (measured for Aged Copper Penny) and deliver 0.84 thermal emissivity, so heat bounces away instead of entering your attic. Kerns receives about 2957 sunshine hours per year, so the reflectance benefit accumulates across hundreds of sunny days. You'll see measurable reductions in cooling load, especially on south- and west-facing slopes. The Cool Roof Rating Council rating confirms the savings are real and quantifiable. Combined with metal's durability, energy efficiency makes the roof pay for itself faster over its lifetime.

What protection does a metal roof have against hail?

Interlock panels carry a UL 2218 Class 4 impact rating—the highest hail classification available—and the Guardian Warranty covers perforation from hailstones up to 1.5 inches. Class 4 rating means the roof can withstand repeated impacts from the largest hailstones insurers track. Many homeowners have seen insurance premium reductions after installing a Class 4-rated metal roof. While Kerns' climate favors snow over hail, the impact resistance is built in and warrantied, giving you peace of mind during any severe weather event.

What warranty comes with an Interlock metal roof in Kerns?

The Guardian Warranty is a lifetime limited material warranty for the original owner, non-prorated and transferable to the next owner for 50 years from completion. It covers rusting, rotting, splitting, cracking, curling, and loss of impact resistance—the failures that plague asphalt and wood roofs. One transferable term adds thousands to your home's resale value and appeal. Interlock has manufactured these panels since 1998 in Delta, BC, and installed them in environments from coastal salt-air homes to Antarctic research stations, proving longevity in extreme conditions far harsher than Kerns' 1468 mm rainfall and 36 annual freeze-thaw cycles.

Can metal roofing look like slate, cedar shake, or tile?

Interlock offers five profiles: Slate, Cedar Shingle, Shake, Standing Seam, and Mediterranean Tile. Each faithfully mimics traditional materials while delivering aluminum's performance and warranty. The Cedar Shingle and Shake profiles suit Pacific Northwest architecture; the Slate and Mediterranean Tile work with contemporary or eclectic designs. The four-way interlocking system is the same across all profiles, so your choice is purely aesthetic. Standing Seam appeals to modern homes and delivers the tightest visual lines. All profiles weigh a fraction of what they replicate, install over existing roofs, and carry identical Class 4 hail and 120 mph wind protection.

Are metal roofs better for the environment than asphalt?

Aluminum is approximately 95% recyclable, so when your Interlock roof eventually reaches end of life—decades from now—the material has genuine second-life value instead of becoming landfill. You'll never tear off and discard an asphalt roof every 15–20 years; one Interlock roof installed over your existing roof eliminates that waste cycle entirely. The manufacturing process in Delta, BC, is efficient, and the light weight reduces transportation energy. The Guardian Warranty's 50-year transferable term means your roof may outlive you as the original owner, maximizing the environmental benefit of the upfront material investment.

Is a metal roof a good choice for Kerns’s climate?

Yes. Kerns 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.
