We decided on metal since we live on the beach

Poulsbo, Washington

To whom it may concern:

We recently needed our old asphalt shingle roof replaced as it was damaged and leaking from recent storm damage. Reviewing our options, we decided on metal since we live on the beach. After looking at the different metal roofs available and looking at online reviews we decided on Interlock. We were not disappointed.

The process was quick and the timeline discussed initially at purchase was met. The company kept us informed during the entire process. Our roof had an additional issue not seen with most roof replacements, it was covered with solar panels. Interlock coordinated the removal and then the reinstallation with our solar installer. The panels needed removing and then the mounting brackets needed to be reinstalled so as to keep the warranty in force; all went well.

I was out of town while some of the roofing was being done, when I returned the roof was completed and all that was needed was the final inspection. I was surprised by the look of the final product, while I had seen pictures the actual product looked much better. The roof looks like “slate” tile, it does not look “metal”. We had comments on the roof by neighbors during and after installation and people at work have asked for more information. I highly recommend Interlock Metal Roof to anyone needing a new roof.

It is a great long term investment

Marysville, Washington

We would like to commend Interlock for your product and service. Our house is 1572 square foot ranch style home. It took two days to install the new roof. No mess no waste. The installation crew was very polite and professional. They didn’t mind me supervising (watching) or asking questions.

Interlock Roofing works as advertised. We have had a wide variety of weather in the last 50 days, heavy rain, hail, and eighty-degree temperatures. I believe that the Interlock roof system makes my Leaf Guard gutters more efficient in shedding the rain than the old asphalt shingles. We didn’t know it was hailing until we looked out the windows. The house is cooler with this roof on, it does reflect the heat.
It is a great long term investment.

The first summer of the new roof was worth the project’s price and exceeded our expectations for performance

Seattle, Washington

Mr. Ross and Interlock Industries,

Kathy and I are very pleased with our new roof. During installation, your crew was able to adapt the project around our 100-year-old chimneys and finally completely seal us against leaks. The first summer of the new roof was worth the project’s price and exceeded our expectations for performance. We did not have the old problems of the attic area overheating. The attic fan barely comes on unless it is a very hot day. But we are no longer feeling the heat on the third floor, where all the bedrooms are. Less heat means more comfortable nights and sleep.

If anyone would like to see how the roof looks or performs, we would be happy to show the roof to people interested in the Interlock Industries product. Even the exterior of the house looks better, but surprisingly the roof does not look like it was covered with a metal material. The selected pattern both fits the look of the house and looks compatible with our neighborhood houses. We care very pleased with the roof and the guarantee that accompanies the roof.

Thank you for this roof.

I am very pleased with the roof and the installation

Renton, Washington

To Ross Peterson and all the fine folks at Interlock Roofing!

Just want to say how pleased I am with my new roof. I have shown it off to a lot of people in and around my neighborhood. I have recommended 6 or 7 people to give Ross a call if they need a new roof. They say they will; I hope they do. But I am very pleased with the roof and the installation job that was done.Thanks again!

New roof has transformed this flat-roof ’60s Seattle house!

Des Moines, Washington


Thank you, Interlock Roofing, for providing a high-quality product and professional installation from which we will receive years of permanent protection from the elements. In addition, the really great thing is how the new roof has transformed this flat-roof ’60s Seattle house! We’re not in the ’60s anymore.

We’ve just completed the worst Seattle winter in 30 years, and the application and quality of the materials is beyond expectations. We have been enjoying the roof through the high winter winds and rain and hail and snow of the Pacific Northwest. People ask if it is noisy when it rains. It is even quieter than the old roof we just replaced. The installation only took about four 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, even down to the trim around the chimney. It looks great! There is no moss, no mold, and no fir needles.

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.

My husband and I would like to thank you for coming to our residence and explaining your product and all of its advantages.

It has undergone many remodels, upgrades, and changes throughout the years with a lot of help from friends and family. We will be celebrating its 100th birthday this year. The new roof is definitely a wonderful way to do so! The whole Interlock family was friendly and extremely easy to work with from the beginning of this process to the end. The job was started on time and finished when promised. We are very pleased with how smoothly the project went and very thankful that we were not the ones on top of the house!

Allyn WA USA Interlock Tudor Brown Metal Slate Roof

Everyone in our neighborhood who have seen it also is impressed

Allyn, Washington

In March of 2016, we contracted with Interlock Lifetime Roofing Systems to replace the cedar shingles on our roof. After a couple of dates were scheduled and changed, the job was finally completed on June 22, 2016.

The work crew was very good – showed up as scheduled and the work was completed in 2 days. That is, old shingles removed and new Interlock system installed.

We are very pleased with the finished look of our roof and have had no problems with it. Everyone in our neighborhood who have seen it also is impressed with the product. We would definitely refer anyone we know to your company if they are looking for a new roof.

We are the envy of our small community

Kalama, Washington

We have been enjoying our Interlock roof for several months.  The planning, purchasing and installation experience was everything we expected it to be – superb.

The original shingles, paper, and staples were removed.  The two installers did these tasks without making a mess in the surrounding garden or the patio. 

A new waterproof barrier was laid out and the new aluminum shingles were installed. To my pleasant surprise, each one was nailed in with 2 aluminum nails. This gives me confidence that this roof is made to last and is excellent value for money.

The installers worked for 3 consecutive days until the entire roof was done. Site cleanup was done at the end of each day.  Some days the 2 installers worked beyond “regular” hours even though it must have been uncomfortable as these were unusually hot days for this area.

Now, our house is much cooler in the summer and warmer in the colder weather.  We have found it be noisier in heavy rain, but not significantly so.  I quite like feeling dry, warm and cozy inside while it is raging outside – we live on a mountain, exposed to the elements. Last year I would go out and count how many shingles had been blown off by the high winds.  I don’t need to do that anymore.

Our neighbors have given us many compliments regarding our new roof – we are the envy of our small community.

Finally, I would recommend Interlock to anyone considering a roof that lasts for many years.  The product is outstanding.

The roof immediately changed the look of our house

Shoreline, Washington

To all at Interlock Roofing,

We have owned our home for 2 years, and have needed a new roof since the day we moved in. Both of us were hesitant to just get a new shingle roof as we are planning to stay in this home for many years to come.

As we researched other roofing alternatives, we found information about Interlock Roofing and their metal roofs. The sales representatives were prompt and very kind, allowing us time to make our decision while giving us detailed information to help guide us in our decision making process.

We had the pleasure of getting an aluminum roof installed by Interlock Roofing in March 2016. The roof immediately changed the look of our house, making it look much newer and brighter. We were getting compliments the day it was installed!  The roofing crew was very polite and friendly, they even took time to play with our dog (who loves people with a passion). After the crew left, you wouldn’t have known we had the roof installed that very day, they did such a good job cleaning up!

We have had our new roof for about 4 months now, and we could not be happier.

Thank you Interlock Roofing!

Torrential rains and winds exceeding 50 mph

Bremerton, WA

February 18, 2016

We had the Interlock Roof installed in November of 2015, since then we have had some torrential rains and winds exceeding 50 mph.  The roof has weathered the storms and is just as sound as the day the workers completed the installation.  We are extremely pleased with the roof and the appearance of the roof.  We are also very pleased that we chose the Interlock roof, both for the appearance and the wear ability of the product.  It is a huge relief for us to know that this is the final roof we will ever have to put on our house and that the product is backed by a lifetime warranty.

Your roofing specialists that installed the roof were very professional, considerate, and thorough in their work.  The property was cleaned and checked when the installation was complete.  They promptly addressed any concerns we had and insured we were totally satisfied prior to completing the project.  The entire crew deserves a hearty well done.

Plaguing issue of a moss growth problem

Brush Prairie, WA

Dear Interlock Industries,

We knew that someday we would need a new roof.  We had been considering various roofing materials as we have a concern about a plaguing issue of a moss growth problem as a result of fir needle build up.  We had to go on the our roof at least one to two times and sometimes more often a month to blow off the roof as the needles would collect everywhere and build up in the roof valleys; plus the additional time necessary to remove the moss.  We spent way too much time on the roof.

We happened to see the Interlock aluminum roof system and after speaking with staff and our friends and doing some research, we made the decision to have your roof system installed this past fall.  We want to let you know that we are happy with the product as well as the style we selected.  We had the deep charcoal grey slate profile installed on our traditional style home.  It looks great!  Many of the neighbors have commented on how nice it looks.  They first thought it would be too commercial looking, but once they saw the end product they were impressed.

All the staff from Robin at the Clark County Fair exhibitors’ booth, Mike Rasmussen, Divisional Sales Manager, as well the roof installers were very professional and good in explaining the product, what was involved in the installation, as well as being responsive and open to addressing our questions, comments and concerns.

Once the product was ready to be delivered the installation date was confirmed.  The installers arrived early on that date and started in on the job.  They were diligent on the installation. They did clean up at the end of each day.  They were open and encouraged questions and any comments we had.  If there was something we noticed that was not quite right they would check and correct.  They were as concerned as we were about a quality job done right.

The roof does well as the valleys do not collect needles anymore.  The only concern/complaint is that the needles do get caught in the interlock sections particularly when it is raining and windy making it difficult to remove them.  We have had a lot of rain since the roof was installed so we have not had a chance to really remove the needles.  Hopefully once the roof and needles dry out; it will be easier to remove them.

But it does appear that we will not have to go on the roof nearly as much as in the past.

Thank you,

Miguel and Linda Chavez
Brush Prairie, WA

The installation team was courteous and professional!

Of the five name brand roofing contractors I screened for this project I chose Interlock and I am very pleased with the roof. Coordination and communication was critical especially since Interlock was to perform the installation immediately following another contractor performing a siding replacement. Communication with the interlock team was great and they remained flexible. Interlock was able to adjust their installation timeline as issues popped up with the siding project. Interlock promptly scheduled and dispatched materials and crew as soon as the siding contractor cleared out. I was a bit concerned about introducing a metal roof to the neighborhood, but could not be happier with the end result. In an effort to help tie everything together I had the siding contractor match the fascia wrap and gutters to the interlock roof black slate finish.

The installation team was courteous, professional, and they notified me of any issues they ran across with the structure during the tear-off phase. Clean-up performed by the installation team was better than that performed by other contractors that had worked at the site. Great attention to detail and they took extra measures to protect sensitive areas around the house. I am currently working with their finance department as I Refinance the house and they are by far the friendliest finance team I have ever worked with. Great communication and customer care standards!

The roof looks amazing and definitely grabs the attention of people driving by. The most amusing reaction so far was while I was watering the plants in the front yard a vehicle drove by, stopped abruptly, turned around, and pulled up into the driveway. A salesman in corporate attire for another roofing company stepped out of the vehicle and started asking questions about the roof. I was very familiar with the brand he represented because their product is rated among the best asphalt roofing products in the country. I thought that was quite amusing because here I am giving him contact information for a competitor . He was interested in something similar for his home so we talked for a bit about the Interlock Roof and he was very impressed. Reminded me of those old Coke versus Pepsi commercials.

The warranty can’t be beat.

Interlock replaced our old shake roof, which was leaking. It was not more than 13 years old. In life you get what your pay for. I went on line and looked at the choices, and it was clear to me that that Interlock was the best choice for our home. I called them right after I did my research. Where I come from, quality is the most important thing when you are looking to buy a new product, especially something as important as roof. We were really unhappy with our last roof, and wanted to get it done right this time, to last for a lifetime. I can’t say anything bad about it. We love the roof, and the installation was great. The warranty can’t be beat. Ross was a great company rep. I did not worry in the least about the price we paid, I don’t want to do the roof again. The neighbors keep asking us about the roof. I keep telling them, don’t think of anything else but Interlock. We’ll see a few more Interlock roofs in this neighborhood by the time I am done telling everyone about the company and the roof.
