Review: June 15, 2016 Completion: April 18, 2016

Thank you Interlock Roofing for providing such a quality product and installation from which we will receive years of permanent protection from the elements. The job went smoothly. The crew showed up early and stayed late, answered all our questions, leaving a clean job site at the end of each day. The attention to detail was impressive. The house was a complex roof with skylights, vents and a masonry chimney. The quality and design of all the types of flashing’s, ridge vent, and fasteners were quite impressive and were expertly installed. The hardworking crew was attentive and stayed late when a rainstorm was expected to ensure we were watertight. This diligent crew was the best representative Interlock can have. From the initial contact at the Home and Garden Show in Portland to the visit from the Interlock Representatives to explain the product and show us the options, the experience was enjoyable and fun. One does not expect such friendliness when dealing with a larger company. We look forward to many years under our new roof.

Review: August 15, 2023 Completion: April 26, 2023

Over eight years ago, I needed a new roof on my over 100 year old house and after significant research, decided to use Interlock Roofing. The installers arrived on time, were professional and completed the job as expected.A few months ago, my shop was in need of a new roof and I needed to do no research- I called Interlock, without hesitation. Working with Ross and Mike was very easy. I expected to have the work started sometime in the summer. But then I received a call that there was an unexpected break and that Interlock could start that day. I readily agreed, and the installers arrived by mid-morning. Once again the installers were polite, professional and were finished quickly. They cleaned up the site well. I am as happy today as I was years ago with Interlock. I have since added another project and am eagerly awaiting Interlock to complete it. I have no doubt that I will receive the same great product and professional installation.

Review: July 15, 2022 Completion: May 16, 2022

We recently had our wood shake roof replaced with an Interlock metal roof that resembles the old wood shake roof. It looks fabulous and Victor and crew did a very professional job and removed all debris from the the old roof. We live among a lot of fir trees and with the ever present fire danger it is good to know we have the assurance that our roof is protected. We recommend Interlock Roofing to anyone looking at metal roofing and would be happy to show off our roof to anyone interested. Positive, Quality, Professionalism, Value, Services: Roof installation

Review: March 21, 2017 Completion: January 27, 2017

Pine needles and more pine needles along with fir boughs each season covers our roof all throughout the year. We are consistently getting on the roof to blow off the needles and clean off the fir boughs. Though the job of cleaning off the roof does not take more than 3 – 4 hours, we were looking for a better way and an easier solution to our situation. Our neighbor was in the process of getting a new roof put on; it was Interlock Roofing Systems. We asked many questions regarding their roof and the options available. Their finished roof looked great. The metal roof in the slate shingles option looked really good. They were very pleased with their roof, the installers, and the installation process. Our sales representatives, Mike and Ross, explained the advantages of a metal roof, the benefits of Interlock Roofing and the installation process, answered all our questions and assured us that we’d be very pleased purchasing an Interlock Roof. Peter and Victor, our installers were personable, explaining their process. We had a couple of snow and ice days prior to our scheduled date, so they had to work hard to clean off and prepare the roof. They worked very diligently in the cold and some days in the heavy rain. Our roof took a few extra days waiting for additional materials to arrive. When it was all done, February 1, 2017, our Interlock Slate shingle roof looked great. We are pleased and are looking forward to years of our beautiful featured addition to our home.

Review: February 18, 2016 Completion: November 30, 2015

We first learned about Interlock Roofing when researching roofing options on the internet. We became interested in a metal roof due to our constant problems with moss and fir needles. We went to the September 2015 Home and Garden Show to learn more. Interlock had a great display at the show, and the representative cleared up some questions we had. We scheduled an appointment, and within a week Ross and Mike came out and explained their product to us. They brought samples of the different styles and " data-wpil-keyword-link="linked">colors of their materials and thoroughly explained how their system worked. They even brought a collection of pictures from previous houses so we could decide the best look for our house. As they were measuring the roof, we watched a video on their company and all of the materials and guarantees they provide. We were impressed by their knowledge and experience. The installation only took about three days. Vladimir and Greg, our installers, were very friendly and worked diligently. They took the time to explain what they were going to do and how they were going to do it. Their craftsmanship really shows on the finished roof! We were extremely impressed when they were waiting on one piece of flashing to be in stock and Vladimir drove all the way from " title="Seattle" data-wpil-keyword-link="linked">Seattle to install the finishing piece. We can tell they take pride in the work. We ended up with a beautiful roof and several people have stopped to ask about our roof. We had received many compliments on how the style complements our home. Now that we have lived with it for a few months, we are not disappointed with our choice. It looks great, there is no moss, and the fir needles rinse off with the rain. It is quiet even in the worst rain storm and best of all, it will be the last roof that this house will ever need. We will likely save energy costs this summer and will greatly reduce, or eliminate altogether, ever having to go on the roof again. We highly recommend Interlock Roofing to anyone looking for a forever roof that looks great. All of the people that we dealt with were very knowledgeable and informative. They were easy to talk to and there was never a high-pressure sales pitch. We wouldn’t hesitate to recommend them or talk to anyone about our very good experience.

Review: February 3, 2016 Completion: June 7, 2015

Our home was recently the lucky recipient of a new aluminum shingle roof by Interlock. We are sure that if our house could, it would be singing! So, my husband I and will gladly speak for it. We cannot say enough good things about the quality of our new roof material and installation. From the first visit with the sales team (thank you Mike and Ross) we were impressed with the professional and trustworthy service of Interlock representatives. The whole job took place right on schedule with lots of communication all along the way. The installation crew (thank you Peter!) was hard working, intent on making sure every detail was done to perfection, considerate of our landscaping and a pleasure to have on our property. The finished product: WOW! We love it! This new Interlock roof not only makes our farmhouse and garage look fabulous, in addition, we are so happy to know we will never scrape moss again, not to mention that we will probably never even replace our roof again! The color and style of the shingles are so pretty and we know our home is protected from the elements like never before. We won’t hesitate to recommend Interlock Roofing whenever we have an opportunity. This company has developed a product that really measures up to everything it advertises. Thank you, everyone at Interlock. We loved doing business with you!

Review: February 3, 2016 Completion: September 18, 2015

We would like to thank Interlock Roofing for the excellent product and service we received when replacing our roof. We began work on our one-hundred-year-old house many years ago and thought that we had always hired competent contractors to complete work that we did not do ourselves. However, when replacing the original tongue and groove eaves last summer, we discovered that our seventeen-year-old composition roof was failing due to poor installation. A relatively small project became a much larger undertaking. Since we live in an area where we have a stand of trees behind us and considerable shade, moss has always been a concern. In an effort to avoid any more issues with a roof, I began researching various alternatives. Then I found Interlock Roofing! I learned more about roofing in a short amount of time than I had to talk with several other suppliers. All my questions were answered and my concerns were addressed. Communication between the sales department and the installation department was top-notch. The crew arrived when scheduled and completed the job in a timely manner. After we considered the job complete, we discovered a small problem. That, too was addressed quickly and without question. If we were to need another roof, we would hire Interlock Roofing again. But the excellent " data-wpil-keyword-link="linked">warranty makes that an improbability. We heartily recommend Interlock Roofing to anyone.

Review: April 25, 2016 Completion: July 30, 2015

To the Interlock Corporation, What can you say about a home improvement experience such as replacing the roof on your house? From the first contact to the completion of the project, it was the most enjoyable experience a person can have when dealing with a large commercial company. From the initial non-high pressure, very informative sales contact from a Home and Garden show to the friendly, efficient and respectful installers to the final personal contact to ensure we were satisfied with the results and that we were enjoying our new roof. The application and quality of the materials are beyond expectations. We have been enjoying the roof through the winter winds and rain, and hail of the Pacific Northwest. Everyone asks if it is noisy and tinny when it rains. We reply, “of course not! “ It is even quieter than the comp roof we just replaced. We ordered the deep charcoal grey slate. After the rain, while still wet, the roof shines and glistens like real slate. It is a welcoming sight compared to the dull comp roofs of our neighbors. Shortly after installation, there was a wedding up the road from us. We heard from a friend who attended that our roof was the " data-wpil-keyword-link="linked">hot topic of discussion since everyone had to drive by our house to reach the wedding. We get many compliments from people who drive by. The installers, while being friendly, are very proud of their workmanship, and we liked the fact that they kept referring to the roof as “their roof”. Hard-working and diligent in the task, they were attentive to every detail. The best onsite reps Interlock could ever have. They were proud of the many years of service working for the company, and that fact, too, lends itself to efficient communication and workflow. The installation happened during the summer during some of the hottest days on record. The installers measured their days, coming early, resting during the hottest times and returning during the coolness of the evenings, doing what needed to be done to get the job done. While more expensive than traditional comp roofs up front, the fact that we never have to replace the roof during our lifetime is well worth it. This house is our forever house, and the best part of our new roof is the fact that my husband will never have to climb up a ladder to clean off the moss that grows so well here in the wet but green northwest. After much investigation and consideration of other metal roofing products on the market, we highly recommend a metal roof, specifically one by Interlock.

Review: August 15, 2022 Completion: May 18, 2022

Company was very attentive to keep us updated on timing for installation. Weather was not cooperating and installation start was much longer than any of us anticipated but we received calls regularly letting us know they hadn't forgotten us. Once the installation was started it was finished in record time. Installers did a great job. We love our roof. It looks great.

Metal Roofing FAQs for Homeowners in Rivergrove

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

Will a metal roof handle Rivergrove's snow and ice buildup?

Yes — aluminum's smooth, interlocking design actually sheds snow and ice better than asphalt. Rivergrove averages about 48 cm of snow yearly with roughly 36 freeze-thaw cycles, creating the exact conditions where ice dams form on traditional roofs. Metal panels won't buckle under snow load, and their low thermal mass means less heat loss through the roof to melt snow at the eaves. Optional snow guards are available if you want to control snow release on lower slopes.

Can an aluminum roof rust in Oregon's wet climate?

Aluminum cannot rust because it contains no iron — the chemical element that causes rust. Instead, aluminum develops a microscopic oxide layer that actually protects the metal and self-heals if scratched. Rivergrove receives about 1,468 mm of rain annually, but that moisture simply cannot trigger rust on aluminum the way it does on steel. The Alunar 70% PVDF fluorocarbon coating (warranted 30 years against fading) adds another defensive layer, making aluminum ideal for Oregon's relentless dampness.

Is a metal roof worth the upfront cost compared to asphalt shingles?

Over a 50-year lifespan, aluminum becomes significantly cheaper than replacing asphalt every 15-20 years. Asphalt requires multiple tear-offs and landfill disposal; Interlock's guardian warranty is lifetime limited and non-prorated for the original owner, then transferable for 50 years. Current financing offers zero payments and zero interest until Spring 2027, or 10% off installation — that timing absorbs the cost difference. You're buying your last roof, not your next one.

Do I need to reinforce my roof structure for a metal roof?

No structural reinforcement is needed. Interlock's aluminum panels weigh as little as 0.41 lb/sq ft (the Shingle profile), making them about 96% lighter than concrete or clay tile. Most existing roofs can support this weight without modification, which means installation often happens directly over your current shingles — no costly demolition. The four-way interlocking design distributes the minimal load evenly across your structure, so older Rivergrove homes can upgrade without engineering work.

What's the installation timeline for a metal roof in Rivergrove?

Installation typically completes in 3-5 days for a standard home, depending on roof complexity and weather. Because aluminum panels are so lightweight, crews can often install over your existing roof, skipping expensive tear-off and disposal steps. Rivergrove's average wind gusts reach 116 km/h, but Interlock panels' four-way interlocking design means they're secured continuously — no lifted panels during installation. The local installer, Interlock Metal Roofing (PNW) Inc., has served the region since 1997 and can coordinate around your schedule.

Will a metal roof help lower cooling costs in summer?

Yes, especially if you choose an energy-efficient color. Interlock's reflective coatings achieve solar reflectance up to 0.55 (Aged Copper Penny profile) and thermal emissivity of 0.84, meaning they bounce heat away rather than absorbing it like asphalt. Rivergrove averages about 2,957 sunshine hours yearly, so a light-colored metal roof measurably reduces how much heat enters your attic during those brighter months. Cool Roof Rating Council ratings confirm the energy payback, and energy-efficiency qualification may qualify you for utility rebates.

How long will an Interlock metal roof actually last?

The Guardian warranty is lifetime limited for the original owner — non-prorated coverage for rusting, rotting, splitting, cracking, curling, and loss of impact resistance. The transferable term extends 50 years from completion to the next owner, effectively guaranteeing the roof's structural integrity across two generations. Combined with the 30-year Alunar coating warranty against fading and chalking, you're protected through every weather pattern Rivergrove throws at it. That's stability asphalt can't match.

How does a metal roof perform in hail, and can it lower insurance premiums?

Interlock achieves UL 2218 Class 4 impact rating — the highest available — and the warranty covers perforation even from hailstones up to 1.5 inches. Aluminum's nonporous structure means hail doesn't create the fracture points that crack asphalt or slate. Many Oregon homeowners qualify for insurance discounts on impact-resistant roofing; contact your carrier with the UL 2218 Class 4 rating and ICC-ES evaluation report ESR-1790 to explore savings. That discount often recovers the installation premium within a few years.

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

Interlock requires minimal maintenance — occasional gutter cleaning and inspecting fasteners after severe wind events. You won't replace cracked shingles, chip away moss, or seal leaks like asphalt and tile owners do. Rivergrove's 36 annual freeze-thaw cycles and 1,468 mm rainfall don't degrade aluminum the way they do asphalt (which curls and splits) or clay tile (which cracks). The CALGreen-verified product confirms reduced maintenance, and the aluminum's self-healing oxide layer handles minor scratches without intervention.

Is a metal roof fire-resistant, and does it matter in Oregon?

Yes — aluminum is noncombustible, and Interlock offers Class A fire classification (the highest rating). While Rivergrove's immediate fire risk depends on location, Class A rating increases resale appeal and may unlock insurance discounts statewide. ICC-ES evaluation report ESR-1790 (reissued 2025) confirms code compliance for IBC/IRC standards. Noncombustible aluminum also means no ember intrusion risk during wildfire conditions, a growing concern for Oregon homeowners. That passive protection outlasts the roof's lifespan.
