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.

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.

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 Arlington Heights

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

How does a metal roof handle Arlington Heights winters with 48 cm of snow and freeze-thaw cycles?

Interlock's four-way interlocking aluminum panels shed snow and ice efficiently because the smooth, hard surface prevents water absorption and ice adhesion — critical in a climate averaging 36 freeze-thaw days per year. The lightweight design (Slate at 0.41 lb/sq ft) means no structural reinforcement needed, yet the panels are warranted to 120 mph wind resistance, handling the gusts to 116 km/h common in winter storms. Unlike asphalt, which degrades under repeated freeze-thaw stress, aluminum's oxide layer self-heals from weather exposure, maintaining integrity through decades of seasonal cycling.

Why choose aluminum roofing instead of steel if both are metal?

Aluminum cannot rust because it contains no iron — the element that oxidizes and corrodes in steel. Instead, aluminum develops a thin, self-healing oxide layer that actually protects the material underneath. Steel requires ongoing paint maintenance and will eventually rust through, especially in wet climates like Arlington Heights, which averages 1468 mm of rain annually. Interlock uses roofing-grade 3105-H24 and 3003-H24 aluminum alloy (ASTM B209) with Alunar 70% PVDF fluorocarbon coating on both sides, warranted 30 years against chalking and fading — engineered for salt-air and high-moisture environments.

Will hail damage my metal roof, and can I get an insurance discount?

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. This rating, combined with aluminum's non-combustible Class A fire availability and 120 mph wind warranty, often qualifies homeowners for insurance premium reductions; speak with your insurer about available credits. In hail-prone regions nationwide, metal roofs have demonstrated superior impact resilience compared to asphalt, and the warranty's coverage means you're protected against the rare perforation event.

Is metal roofing worth the price when asphalt costs less upfront?

Over a 50-year horizon, Interlock's lifetime limited, non-prorated Guardian Warranty — transferable to the next owner for 50 years from completion — typically costs less per year than replacing asphalt every 15–20 years. Current financing includes no payments and no interest until Spring 2027 or 10% off installation, reducing upfront cost. Asphalt tear-offs generate landfill waste and labor; aluminum eliminates that cycle. A homeowner in Arlington Heights avoiding three asphalt replacements, plus tear-off labor and disposal, over the life of one Interlock roof recovers the material cost difference and gains a transferable warranty that buyers value.

Do metal roofs really save energy, or is that marketing?

Interlock's energy-efficient colors with thermal emissivity of 0.84 and solar reflectance up to 0.55 (Aged Copper Penny) reflect heat that asphalt absorbs, reducing cooling loads — measurable in summer months when Arlington Heights averages 2957 sunshine hours per year. Cool Roof Rating Council verification confirms the reflectance rating. In climates with significant seasonal sun and temperature swings (mean 11.5°C with daily-max winds ~15 km/h), reflective metal roofing lowers air-conditioning runtime. The coating is warranted 30 years, so the energy benefit persists without degradation.

How much maintenance does a metal roof need compared to asphalt or wood shake?

Aluminum requires virtually no maintenance — no re-coating, no moss treatment, no wood sealing. Asphalt roofs need periodic sealing and are prone to algae in wet climates; wood shake requires fungicide and splits in freeze-thaw cycles like Arlington Heights' average 36 per year. Interlock's four-way interlocking panels and Alunar coating (PVDF fluorocarbon, 30-year warranty) shed debris and resist weathering passively. The material is CALGreen-verified for reduced maintenance. One-time gutter cleaning suffices; no special tools or professional visits required for the roof surface itself.

Can my house handle a metal roof without expensive structural work?

Yes — Interlock aluminum is extraordinarily light. The Slate profile installs at 0.41 lb/sq ft, and even the Mediterranean Tile (the heaviest profile at ~0.59 lb/sq ft) is about 96% lighter than concrete or clay tile. Most homes can accept this weight without reinforcement, and Interlock often installs directly over existing roofs, eliminating tear-off labor and cost. The ICC-ES evaluation report ESR-1790 (reissued 2025) confirms code compliance and addresses structural load. A structural engineer may review your home, but lightweight aluminum typically requires none of the costly beam or rafter upgrades that slate or tile demand.

How long does metal roof installation take, and can you install over my old roof?

Installation timeline depends on roof size and complexity; most residential projects complete in 1–3 weeks. Interlock can install over most existing asphalt or wood roofing without tear-off, reducing labor cost and waste — especially valuable when avoiding landfill disposal of asphalt shingles. The four-way interlocking panels fasten directly to the existing deck, and a solid substrate with proper underlayment ensures water-tight performance even under Arlington Heights' 1468 mm annual rainfall. Your local installer, Interlock Metal Roofing (PNW) Inc., serving the region since 1997, can assess your deck during a no-cost estimate.

Is a metal roof fire-resistant in wildfire-prone Oregon?

Interlock aluminum is non-combustible and available with Class A fire classification — the highest rating under building codes. The ICC-ES evaluation ESR-1790 confirms code compliance for fire performance. Unlike asphalt (which is flammable) or wood shake (which is highly combustible), aluminum will not ignite, spread flame, or contribute fuel to a wildfire or structure fire. In Oregon's fire-risk environment, this non-combustibility also reduces homeowner insurance costs and meets increasingly strict defensible-space roofing codes. The material's durability means this protection persists for the lifetime of the roof.

How does metal roofing handle heavy rain — is it prone to leaks?

Interlock's four-way interlocking aluminum panels and solid-deck installation with underlayment provide superior water shedding in high-rainfall climates like Arlington Heights (1468 mm annually). The overlapping seams mechanically lock together, preventing water infiltration at panel joints — a common failure point in traditional roofing. Combined with proper slope and flashing, the design exceeds IRC/IBC code standards (ESR-1790). Metal's hard, non-porous surface sheds water faster than asphalt, which absorbs moisture and degrades. When installed to Interlock's specification by a certified installer, metal roofing is demonstrably more leak-resistant than asphalt in sustained heavy rain.

Is a metal roof a good choice for Arlington Heights’s climate?

Yes. Arlington Heights 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.
