With this roofing - problem solved

March 23, 2003

For me, the change to a metal roof is something I have thought about for some time as I have had nothing but problems with the new asphalt put on ten years ago. Ice dams and leaks have been a problem from the beginning of which I thought taking off the gutter would help. Next was to pay to have a three-foot piece of aluminum put in along the length of the roof, resulting in snow dams above the aluminum strip. The next thing to try was electric wires, which were somewhat successful, but meant taking down and putting up yearly. At 54, to be on a ladder dealing with wires and ice dams is okay, but how about 64 or 74? Some new way to roof had to be the answer. In New Hampshire, where my brother and I have a summer place, a new cabin was being built, and it had long metal panels which didn’t look too bad but were painted. The idea that an option was out there. Interlock was the better choice for a metal-type roof and looked better too. The cost of snow seals and new shingles, stripping off two layers, and the cost of recycling in twenty years led me to see that non-asphalt does cost more initially, but how about in the long run? Probably not. With my new Interlock Roof, time spent on the roof, don’t see any need for snow dams, as snow slides off. No need for a roof rake or wires. Loudness in the rain, not noticeable. The appearance looks great. With this roofing – the problem is solved; it’s on to other needed repairs.

This new roof has put our concerns about water damage to rest

March 9, 2003

Kathy and I would like to express our thanks to you and the installation men from INTERLOCK for installing a very attractive roof that has already elicited praise and accolades from our neighbors. We have already seen the benefits of the INTERLOCK system with all of the snow that has fallen in recent weeks. As described in your marketing materials: it just slides right off. This new roof has put our concerns about water damage to rest since we invested a considerable amount to have five rooms of our home renovated in August-September 2002. We like to think of this new roof as the "icing on the cake." We hope to direct our neighbors in your direction in the near future when they decide they, too, would like to add the same impressive roofing structure to their home's value. Finally, we would like to give a special thank you to the installation team for installing our roof under less than perfect weather conditions. February 2003 had its share of record amounts of snow and cold weather, and your team was unfazed by these extremes. They completed the task in two weeks and never rushed the job. It is truly a testament that you have dedicated staff that strives to deliver on Interlock’s mission statement. BRAVO!

And, no, we don't hear "pitter patter" when it rains!

Addressed to: Popular Mechanics I have read your recent issue which included a section about roofing materials. I was surprised your excellent publication did not include information about aluminum metal roofs in that section. We recently had one installed and are quite pleased with the appearance. Our roof was installed by Interlock Industries, based in Vancouver. Their shingles come in many colors and somewhat resemble the look of an asphalt shingle roof. However, unlike asphalt shingle and other roofing types, our roof has a lifetime, non-prorated, fully transferable factory warranty. It is fireproof, rot proof, energy efficient and can withstand winds in excess of 100mph. The cost per square foot is more expensive than asphalt shingle but not much more expensive than a 30 year warranted asphalt roof. Much has been written concerning the rapid deterioration of today's asphalt roofs and I would suspect your readers would be interested in learning more. And, no, we don't hear "pitter patter" when it rains!

The Interlock System is actually quieter in the rain than the existing asphalt shingles were

February 17, 2003

I am writing to compliment you on your excellent product and to tell you how much I enjoy having it on my home. The existing roof on my house was about 20 years old and was showing its age in a few places. When I heard about the Interlock Roofing System, I knew it was the right solution for me. Your salesman Daniel Adolfson was very thorough in his presentation and really took the time to explain the System in an easily understood manner. Your installation crew was prompt and courteous, finishing the job in only a few days. Since completing the job, we have had snow and rain. I have been amazed at the performance in either type of weather. The snow simply slides off and the Interlock System is actually quieter in the rain than the existing asphalt shingles were. In closing, I thank you for an excellent product and a job well done.

We have already noticed the benefits that the salesperson had sold us on

January 9, 2003

I would like to take this time to thank you and your installers for the high-quality workmanship and timely installation of my new Interlock metal roofing system. The installation was very well performed and in a timely manner. I have had no problems in recommending your company and product to many of my friends and family when the topic of roofing has come up. We have already noticed the benefits that the salesperson had sold us on and we look forward to many years of hassle-free “coverage” your system provides.

Thank you, Lock Corley

This sort of customer service is what really separates companies that are in it for the long haul

January 3, 2003

I just wanted to take a moment to commend Interlock on a great product and thank you personally for your follow through after installation. I am pleased with the roof overall because it's good looking and works well. I get compliments about the new roof frequently. The description you provided of what to expect from beginning to end and what was delivered was consistent. This is such a simple thing to do but a surprising number of companies simply don't execute on their promises so I was pleased with the end result Interlock provided. The crew that removed my old roof and installed the new one was courteous and professional. They did a good job of cleaning up the job site each day and obviously take pride in their work. The only thing I would say was a drawback is that I had filled out the customer satisfaction survey before the dumpster was removed from my front yard. After the dumpster was removed I discovered two long indentations on my front lawn over a foot deep caused by the weight of the fully loaded dumpster. When I called you about it, you said you would correct it and now it has been corrected. This sort of customer service is what really separates companies that are in it for the long haul. I appreciate your follow up and the fact that you were able to correct the only item where I was not completely satisfied. I recommend Interlock to anyone considering a roof replacement based on the merits of the product alone. I had done a good amount of research in Consumer Reports on the longevity of different roof types as you know so there was no question in my mind that I wanted a metal roof but I didn't know how nice the end result would turn out. Your product combined with outstanding customer service is an unmatched offering. Consider me a reference for other potential customers curious about the experience they had with Interlock

Thank you for being such an excellent firm

November 29, 2002

My wife and I want to express our complete satisfaction with the "Aged Copper" roof your firm installed on our "Barn-house" and gazebo. The two roofs have a high quality appearance and they enhance the looks of the property. We are looking forward to many years of satisfaction. We are now planning to re-paint the house with a color to better blend with the roof. The work performed by your installers was outstanding. They were friendly and very professional. They worked efficiently and energetically, and it was obvious they had the skills to do the job. Thank you for being such an excellent firm.

No difference in sound compared to our old roof

November 27, 2002

I wanted to let you know how happy my wife and I are with our new Interlock roof and the quality of the installation work. The installers presented themselves in a very professional manner. They took great pride in their job and worked on our home as if it was their own. At the end of the day, they always cleaned up after themselves and never inconvenienced my family. They truly were a wonderful crew! The roof looks fantastic. It is much sharper and cleaner looking than our old roof. Since it was completed, we have had several hard rainstorms. The roof performed very well. One of our initial concerns was if rain hitting this new roof would be louder than our old. On those stormy nights, our fears were quickly put to rest. There was no difference in sound compared to our old roof. Then, the night before Thanksgiving, we had a snowstorm. Thanksgiving Day was nice and sunny, and our house was the only one with no snow on the roof. The Interlock roof is, by far, the best home improvement project I have undertaken; it is wonderful knowing I will never have to worry about my roof again. Thanks for the great product and service.

He went beyond the call of duty to perform an excellent job

July 16, 2002

This letter regards the installation of a new roof on our house using your products. First of all, we are extremely pleased with your product. We would be happy to recommend it as an excellent product. Next, I would like to commend you on your choice of an installer for our new roof. I do not think you could have chosen a better installer. From the very first day on the job, it was obvious that Mr. Ritter was a highly competent tradesperson. He pointed out many errors that had been made on the original roofing system. In addition he advised us on the necessary corrective measures. In my estimation he went beyond the call of duty to perform an excellent job. I feel you company should be very pleased to have a craftsman with such a good sense of responsibility, desire and ability to do an excellent job. Once again, we are extremely pleased with your product and the workmanship of Mr. Ritter.

Yours truly, M.A. Lantz

The installers did a superb job

When we got in touch with Interlock Industries our roofing problems were solved

March 27, 2002

I just wanted to write this note to thank you for our new roof. When we first bought this house 3 years ago we knew that we would need a new roof soon. When we got in touch with Interlock Industries our roofing problems were solved. We were tired of going up on the roof year after year trying to repair the old shingles. After every storm shingles would blow off and end up scattered all over the yard. Now our troubles are over for LIFE!  The high cost is worth not having to go up there and try to make repairs that would just blow away with the next high winds, I also love the fact that the snow just falls right off with out any effort from us having to push it off.  I was a little worried about the rain and how loud it would be but I haven't been able to notice any big difference in sound at all. I wanted to thank the crew that installed the roof as well. They did a great job and they were very personable people that knew what they were doing. The job was done in a very timely manner. I was actually shocked at how soon toe product was delivered and then installed. Thank you Interlock Industries for this roof of a lifetime!  We are very happy with the outcome and if we do end up buying another house we would definitely have one of these roots installed on it as well.

We are extremely pleased with the completed result and the enhancement to our home

March 13, 2002

There are two reasons for this letter to you. First, both my wife and I wish to express our satisfaction with your roofing product. We are extremely pleased with the completed result and the enhancement to our home. Second, we wish to take this opportunity to commend your roof installer Mr. Larry Koster he is the kind of exceptional employee that any employer would be fortunate to have working for him. He persevered in spite of extreme adverse weather conditions, which included, rain, sleet, snow, hail, wind and cold, in order to complete the job. He is to be congratulated for being such a conscientious efficient tradesman.

I chose Interlock primarily because it is guaranteed for the life of the house

December 1, 2001

I had an Interlock roof put on my house recently. I am pleased with it. The color of the roof matches my house nicely. Your employees did a good job of cleaning up the debris, especially considering the fact that one-half of my existing roof had to be stripped of its existing two layers of asphalt shingles. I would recommend this roof to others for these reasons and also for the following reasons:

When I bought my house over four years ago, it was ten years old and had an asphalt roof; the home inspector who looked at the house noticed that a few of the shingles were lifting and that there were some gaps in the chimney flashing that he said were consistent with normal wear and tear over the years. When I hired a contractor to make repairs, I was surprised to learn from him that many of the asphalt shingles were cracked and that one-half of the roof would need to be re-shingled; my mother and I have since heard from several sources that during the 1930s there were problems with bad batches of asphalt roofing shingles being manufactured.

Earlier this year, I had a minor roof leak in the half of the roof that was not re-shingled. The contractor who repaired it said that this half of the roof would probably last 3 or 4 more years, I’ve heard that an asphalt roof could last for 20 years, but this was not the case with my house.

I clearly wanted a roof that would last a good long time and wanted an alternative to asphalt shingles. I chose Interlock primarily because it is guaranteed for the life of the house. I also like Interlock for other reasons as well.

The aluminum shingles interlock with each other on all sides. This prevents the shingles from lifting over time, a problem that I had with the previous asphalt roof on my house.

I’ve heard that Interlock roofs are more energy efficient than other roofs. Energy efficiency is important to me and should be to everyone in this day and age and the future to come.

Finally, another reason that I like Interlock roofing is for safety reasons. While installing any roof on the house involves unavoidable safety risks to the roofing installers because of Interlock's lifetime guarantee, no one should have to go up on the roof again once it is installed. During the life of a house, this reduces the amount of time that the safety of individuals who work on the roof of the house is at risk. With asphalt roofing on a house that requires replacing every year of the house’s life, there is an increased risk of a roofing installer working on the roof of that house getting hurt.

The concept of permanent roofing system with a lifetime transferable warranty, will give us peace of mind, as well as increase the value of our property

November 25, 2001

My Wife and I are very pleased with our new aluminum roof it has been almost four months since Interlock crew in so efficient and timely manner installed it. Some years ago after my asphalt shingles roof No.3, I promised myself never again with the asphalt crap, I HATE IT (Heavy, Flammable, Granules- shedding-eaves-clogging, gone with the wind, etc, etc.). The concept of permanent roofing system with a lifetime transferable warranty, will give us peace of mind, as well as increase the value of our property. After some hesitation regarding the cost, looking in retrospect, I believe it -was the right decision to make. The only thing left to do now is to sit, and relax under a maintenance free Interlock roof. Finally, hats off to the installation crew, very helpful in answering technical question, posed to them on the precautions they took to prevent damage to property, on how clean they daily left the surroundings.

Thank you, Sirs, Sincerely, Peter Firsoff

We are proud to display our home to the town of Westlock

October 17, 2001

For the last five years my husband had been hinting hard that our house needed a new roof. My reply was, I need a new carpet and some painting done. His reply was. "A new carpet won't be very pretty when it is wet." Every summer storm showed lots of shingle debris on the deck and lawn. I was still reluctant to get new shingles. On a whim we attended a home show in Edmonton in the spring. It was very interesting and we saw several companies showing new shingles. When we came to the Interlock booth, we were met by a friendly salesperson who explained their product. To this day I can not believe that I fell in Love with new shingles.  We were both sold instantly. We were then paid a visit by the salesperson who did a good job of selling his product, even though he didn't have to. We were committed. The installation of the product was timely and went very smoothly. The staff were very friendly and efficient. Our roof looked great and the yard was left very clean. We are proud to display our home to the town of Westlock.

Sincerely, Marion Zilinski Proud Home Owner PS. The new carpet is on order

Very professional and had some difficult weather conditions to work with

July 27, 2000

Dear Inter Lock Roofing: Subject: roof installation I would like to express my recommendation for your installers, Mike and Nedjo. It was a pleasure to work with these gentlemen; when it is time to do these other roofs on our place I want them back, and not hesitate to pass their names to others. They were both very professional and had some difficult weather conditions to work with.

Thank you for making the excellent product

July 5, 2000

When my husband Richard said he wanted to put a metal roof on this 1929 English Tudor house, I thought he had gone around the bend, maybe several bends. After seeing the pictures and hearing about the features, I started to become a convert. Now that the job is down, I know that we made the right decision for several reasons. First, the black Interlock shingles look so appropriate on this house. In certain lights it even appears to look like slate. Many neighbors and friends have commented on how very attractive it looks, Secondly, the workmen did such a professional job. They were meticulous at each step of the process and, we are confident, that their craftsmanship was excellent. Each day that they were here they worked diligently and conscientiously making sure that every step of their work was done to the highest expectations. In addition, they were quiet and tried not to interrupt our daily routine. Third, we are most pleased about all the high quality features of the product: the durability, the appearance, and the fact that it is maintenance free. Thank you for making the excellent product.

Sincerely, Susan and Richard Alvord

If the roof is as good as it appears and is warranted for, the cost is justified

April 11, 2000

In less than a week since the new Interlock roof was installed on our house we have had several compliments. It is somewhat a coincidence that the color of paint we put on the gutters and gable ends a couple of years ago is compatible with the weathered copper color of the shingles. Most homes in our neighborhood are between twenty and thirty years of age. All have been re-roofed. Some need replacement again. They should consider Interlock. The weather was not always the best during the job. The installers seemed to know exactly what to do and how to do it. If the roof is as good as it appears and is warranted for, the cost is justified. In comparison with anything else around we're quite proud of it.

Sincerely, Donald Sherp

My 35-year-old shingles failed after 12 years

April 10, 2000

My Interlock roof looks very nice, and I am very pleased. The workers were neat, courteous, and great craftsmen. The reason for my new roof was that my 35-year-old shingles failed after 12 years. It had many leaks, and I was about to replace it. Then I saw Interlocks' flyer and decided to give them a call at Walpole. Now, I have a beautiful mountain blue roof. I get so many compliments on it all the time. I know that I have made the correct choice, and I will benefit from it in the many years to come.

Sincerely Yours, John Howard

My new Interlock roof has satisfied me beyond all expectation

March 26, 2000

It has now been two years since the installation of metal interlocking shingles on the roof of my residence in Ottawa. As I indicated to the salesman at the time, if after two years I was totally satisfied with the installation and performance of my new roof I would take the time to extol the virtues of the Interlock system. To date, I have indeed been most impressed with the performance of my roof prior to the installation of the Interlock system, I was required to change the asphalt shingles on my roof every eight to ten years. Because I have a low slope roof on my home, I was not immune from the occasional leak between re-shingling jobs. Re-shingling a roof is a major financial investment, and obviously more so when considering an upgrade from the standard asphalt shingles used by the construction industry; therefore, prior to my decision to accept the Interlock roof system, I had a number of concerns, such as fading, longevity, performance, workmanship, appearance, etc. I can categorically state that, to date, initial apprehensions have not materialized. My new Interlock roof has satisfied me beyond all expectations. Besides the leak-free performance of my new root, the next greatest benefit is the appearance of the Interlock shingles versus the conventional asphalt shingles. Homes with Interlock systems have a much greater aesthetic appearance, as attested to by friends, neighbours and strangers passing through the area. This, in addition to the lifetime warranty (50 years on the resale of the home), greatly enhances the marketability of the home on re-sale. To say I am pleased as punch with my new roofing system is an understatement. I have no objection to Interlock Industries using my endorsement of their product. I have not, nor will I receive any financial or other benefits for this endorsement. Satisfaction and peace of mind (especially when it rains) are my rewards. Thank you Interlock Industries, for a job well done.

Thank you, R.J. Bens

Another advantage of a very conductive aluminum roof is that it forms a Faraday cage around the house

November 2, 1999

The Kirkwood family is the proud owner of a new, red, Interlock aluminum alloy tile roof, installed this July. This new roof greatly improved the look of our home in replacing our old wood shingle roof, whose life had expired. We were happy that the new roof could be installed directly over the old wood roof, without the messy ripping up that we have observed each of our neighbors go through. The installation crew were extremely courteous and worked very hard to complete the installation in 3 days. We were also impressed with the promptness of delivery for a custom made roof. It was only two weeks from order to installation. What a difference! On a bright sunny day the red surface of the garage roof actually glows against the second story of the house. Our neighbors from up to a block away have commented that the house looks brand new. Sometimes we think they  enjoy it more than we do. That is not completely true, however, because I will not miss cleaning the maple nuts, leaves and moss, applying water sealer then patching the wood shingle splits to prevent leaks. We waited in sending this letter until the  middle of fall, to see how the new roof handles the maples nuts and leaves, as we live in a forest setting. On a rainy, windy, night this week, the rain washed the leaves down into the gutters, leaving the roof clean. It is much easier to clean the gutters than the roof. Our house is also located near electric power transmission lines and stray electric fields from them interrupt AM radio signals. Another advantage of a very conductive aluminum roof is that it forms a Faraday cage around the house, eliminating the AM interruption and also potential health hazards. The roof has also improved reception from our outside antenna for TV signals. We are very happy with our new roof.

The haunted house look changed instantly into desirable real estate

October 26, 1999

What a substantial difference the Interlock aluminum roof has made to the appearance of my hundred year old house. The haunted house look changed instantly into desirable real estate. The people who sold me the house have said they wish they had asked more for it now! My previous roofer, who I have used for many years on five different roofs with excellent results; drove by and said he knew it was a good job. He also wanted to recommend Interlock roofing to another customer who wanted something better than composition roofing. The service was great, the sheet metal engineers were industrious, exacting workers, and there have been no problems with anything. It looks so solid and neat; I cannot describe it exactly, but I will never be happy with composition roofing again. The leaves slide right off so it is always clean, and shows off the gables and fancy lines of the house so well... I love it!

A very satisfied customer, Marilyn Young

This is to advise you that Steve Graetsch and Jim Barnes have completed the installation of our Supertile aluminum roof. They have worked beyond the call of duty, in adverse conditions, and done an excellent job. My wife and I are extremely pleased with their professionalism, their knowledge, and the quality of their work. We heartily recommend their work to all, and have heard nothing but praise from all who have seen the new roof.

The difference from before to after is spectacular

July 6, 1999

Thanks so much for improving the appearance of our home. The difference from before to after is spectacular. It was also nice to have Interlock install gutters as we did not have them before. The job was done quickly (within a week), and the clean up was amazing!! Having had numerous problems with roofers in the past and not having much trust in roofers, It was a pleasure to work with you and have such an easy process with no hassle and a fabulous product to have for 40 years!! Thank you, Thank you, Thank you!!!
