Joliet, IL — Roof Review — Metal roof is pricey — Well worth the extra money

A metal roof is pricey - well worth the extra money

Joliet, Illinois


Last March I started looking for a roofing company when I found Interlock Roofing. I was curious about what a metal roof would cost and the durability of the materials. To my surprise, although the cost of a metal roof is pricey it is well worth the extra money. I will never have to worry about having to replace a single shingle again! In the last 2 years, I have had a lot of repairs done on my roof using contractors who were not very good as I soon found out. I kept losing shingles with every wind that would pop up due to poor workmanship. Please believe me that a metal roof installed by Interlock is guaranteed to not come apart, fade or discolor or they will fix any issues found for the life of the roof although I do not expect to have to make a call to them if ever.

Interlocks workers spent 2.5 days installing my roof working 11 hours per day. They are very dependable and knowledgeable. I would recommend this company 100 percent!

Plano, IL — Roof Review — Metal roof 25 year old farmhouse — Country Living Magazine

Knowing that this roof will last a lifetime, literally, is very comforting

Plano, Illinois


We built our house 25 years ago from plans I found in Country Living Magazine.  It is a perfect blend of the “new” house my husband wanted and the “old” farmhouse that I wanted, nestled at the end of a quiet cul-de-sac it was a perfect place to raise our kids.  We still love it just as much as we did then…but it was in need of some updates.  It was time to replace the original roof, and why not repaint too?

This has been the summer to do it all.

We looked at asphalt shingles, nothing wowed me.  Some colors were “close” but it was still a lot of money to spend on something that was just o.k.  I kept thinking about a metal roof,  but my husband wanted something traditional.    Thank goodness an advertisement popped up on my computer one day.  We loved the look but wondered how they would really look.  I did a little research and made the call.  We were impressed!!!  Not an easy feat!

The colors were fabulous!  A perfect blend of what we were both wanting.  After months of discussions and searching, we bought our roof that night.  I so wish we had started with Interlock!

Thankfully because of when we ordered, there were a few weeks wait time… Just enough to get the painter in to paint, and enough time to change the porch pillars too. Jesse was our crew leader for installation,  he was great and so were all members of our install crew.  They were so polite and kept the area cleaned up on a daily basis.  I love the new look!  And knowing that this roof will last a lifetime, literally, is very comforting.

Thanks for a job well done.

Batavia, IL — Roof Review — Interlock Was The Only Company That Installed Their Own Product

Interlock was the only company that installed their own product

Batavia, Illinois


After researching the various metal roof manufacturers and metal roofs in general we chose Interlock. In addition to offering a great selection of styles, Interlock was the only company that installed their own product. I liked being able to deal with one company regardless of the issue.

My wife and I are very happy with our choice and results. The curb appeal has been enhanced and we have gotten the thumbs from our neighbors for the great look. I am happy with the performance of the roof and I have found everything touted about this roof to be true. We had a tremendous thunderstorm come through and a downpour that was second to none. The noise from the rain hitting the roof was quieter than on the old shingle roof. I am eagerly anticipating the summer for the cooling benefit I expect to receive.

Installation of the roof was flawless. The crew was very courteous and hard working. It was obvious they were very skilled and knew what they were doing. They took the time to do it right. I believe they treated my property as if it was their very own. Communication was exceptional and I was kept abreast of what had been and what was going to be done each day. I even received a call from the salesperson following up which was totally unexpected.

I would not hesitate to recommend Interlock to anyone who was looking for a metal roof.

Carol Stream, IL — Roof Review — Roof is not any louder during several of the storms

The roof is not any louder during several of the storms we have had already

Carol Stream, Illinois


Our new roof is beautiful! We have received so many compliments and inquiries since our Interlock roof was installed four weeks ago. John delivered on his promise with a quality product and set up the stage for what was to come, answering all our early questions and showing us the information we were looking for to make a confident decision.  He provided us installation pictures of previous jobs, the product specifications, color and type of samples, historical data on product performance and much more.  Dal from customer service responded quickly with dates when material was arriving and dates for the installation.  After some concerns about having to travel for work and being out of town, Al communicated well and they worked around my travel schedule and my family appreciated this greatly.

The roof is not any louder during several of the storms we have had already, than before. Despite a few outside temperatures reaching the 80s and sunny, the inside of the house has stayed cool without needing to turn on the AC or ceiling fans. It really is a new experience to walk into our second level rooms and not have it feel warmer than the lower level.

The installation crew did a great job. They told us everything they were doing and answered all of our questions. The fire department even stopped by during installation to ask what it was! The crew completed the job in 4 days, working over the weekend to finish before the next storm. They left the yard clean every night, and they cleared out the gutters from all of the debris.  After watching the team install the new roof safely, we have come to appreciate the craftsmanship that comes with installing this type of roof.  The crews are proud of the product and their care shows in the installation.  Putting on this new roof requires a lot of skill, a lot of hours, and experience that I think new owners won’t realize until observing them and going through it.  Minimal waste scraps, efficiently making thousands of measurements and metal shaping to perfectly fit all the corners and bends is a testament to the experience our crew lead by Jesse and Sal had.  

This Interlock company has been great and there have been so many people referenced here that have worked to provide us a great customer experience.  To the whole team, great job and thank you.  We look forward to the many years this roof will continuously perform as it was designed and the many more times we will appreciate the beauty of it.

Des Plaines, IL — Roof Review — Two rainstorms, a four-inch snowfall, and minute heavy hailstorm

Worth every penny as you never have to re-shingle again

Des Plaines, Illinois


Dear Mr. Mondschean

It has been slightly more than one week since the installation was completed and I thought I would offer the following:


Since completion, we have had two rainstorms, a four-inch snowfall, and minute heavy hailstorm. The only annoying noise experienced (…think of a loud combo of cymbals & snare drums) was during the hailstorm. However, I am sure that with standard shingles, the amplitude would have been the same, only at a lower frequency (i.e. a bowling alley and/or Niagara Falls).


Juan & Alex did an excellent job exercising care around existing installations (i.e. new plantings, aerials, wiring … ) and worked diligently even during the 50mph windy/gusty Wednesday. Upon completion, clean-up was very well done … not perfect, but better than I’ve seen in the last 20 years. Jesse also did well with coordination and follow-up.


I’m impressed with the materials & engineering involved in your roofing system. The interlocking method provides good rigidity & hopefully good liquid seepage resistance, while the individual shingle size should allow proper thermal expansion/contraction to prevent buckling. Visually, I’m completely satisfied. Performance-wise, ask me again in one year after everything has gone through a complete spring-summer-fall-winter cycle, thus establishing the credibility of your advertising propaganda.

Thank you for your efforts.

La Grange, IL — Roof Review — Discount on the insurance premium

I would highly recommend this company

La Grange, Illinois


Dear John,

I wish I had known about the Interlock Roofing System before I put the last new roof on twenty years ago. If I had, I would not have had to replace it again now. At least now I won’t need to worry about the roof ever again because of the lifetime limited warranty with its 50 year transferable and non-prorated features.

When I first suggested to my wife that we consider a metal roof, she was concerned about the noise level during storms. This concern disappeared after the first storm as the noise level was much less than before the metal roof was installed.

Speaking of installation, we were very happy with the way your installation crew did their job. They were careful with our landscaping, cleaned up each day and when they finished and left, the only sign of their having been there was the new roof itself.

The new Interlock roof looks great, and we have been complimented on it by many neighbors as well as people passing by. Our home insurance company was also happy with the new roof and its Class 4 hail impact resistant rating, which will give us a discount on the insurance premium.

We are very satisfied with the entire process of getting a new roof installed. From the initial discussion with the sales representative, the installation crew, and final results, there were no surprises. We will also be very happy twenty years from now when we don’t have to put another roof on the house.

Thank you,

Dear Mark,

I would like to provide you some feedback on the first phase of work done on our project at the Church of the Nazarene, in Chicago Heights. Before going into the details of the work perforn1ed, I would like you to know how pleased I was putting together this project with your sale manager, John Mondschean. John’s a pleasure to work with, always prompt, courteous, and clear with feedback and follow-ups. He not only knew his product well but proved to be very helpful in overcoming the various issues of the job. John was able to meet our needs while staying within the budget by offering helpful suggestions and options. I could only hope to have such a knowledgeable, responsible person to work with on future projects.

As for the first phase of work, installing a 50 year PVC membrane roof with insulation over the existing roof, integrating metal flashings and adding badly needed ventilation to the top flat area above our sanctuary.
This job was performed by a group of tradesmen that took pride in their workmanship, Not only did they arrive at the job site on time each workday, they never left without ensuring that the work site was clean and secure, daily. For me, that was a big plus. I watched the installation and was pleased with the care utilized by the workmen. Roofing seams were straight, smooth and clean. Details cuts and welded fitting were secured around each of the skylights with care. I was pleased with your workers and their workmanship as witnessed on the job site. Mark, most of all, I’m pleased to inform you that my biggest pet peeve was adhered to without fault, Safety. Your workmen used proper fall protections with tie-offs, body harnesses, and safety lanyards. All ladders and guards were properly secured. At the completion of the job, the work area was thoroughly cleaned and all scrap materials were removed from the work site.

Thank you for a job well done. This job was a well-managed and professionally carried out. I look forward to the second phase of our project in the fall.

Schaumburg, IL — Roof Review — Four factors need to be considered

Four factors need to be considered

Schaumburg, Illinois


We had replaced one roof in the time we had owned our home, and now it was time for the second replacement. I began to wonder if there were any alternatives to old asphalt technology. Also, we had two concerns about asphalt, the first is that it is not clean from an environmental standpoint and second, asphalt is oil based which means its cost is linked with the price of oil. I noticed that many commercial buildings had metal roofs. My wife and I usually do a lot of deep research for major home projects. We began looking into the possibility of replacing the current roof with metal. Our research indicated that there were residential metal roofs available in various metals and styles. Four factors need to be considered.

  1. Type of metal. We chose aluminum over steel. It’s lighter and less susceptible to corrosion although corrosion is not a major factor due to the various coatings and treatments applied to both metals during the manufacturing process.
  2. Structural assembly. We liked the Interlock method of attaching the panels to each other and the roof base. When complete the system is structurally sound and waterproof.
  3. Installation process. Installing a metal roof requires experience. Installation is different from that of an asphalt roof. During our research, we had a hard time locating installers that had experience installing residential metal roofs. This was another reason that we chose Interlock. They are associated with installation crews who have the knowledge and experience required for working with the Interlock product.
  4. The only other factor to consider is the style and color, and there are many to choose from.

Installation was uneventful, the crew was courteous and they explained exactly what they were doing and answered any questions that we had. The roof looks beautiful and we have had many compliments on it since it was installed two weeks ago. We are very happy that we chose Interlock for this project and highly recommend them.

Berwyn, IL — Roof Review — This is one investment in our house that will really pay off

This is one investment in our house that will really pay off

Berwyn, Illinois


Our roof was completed last month and I cannot tell you how many compliments we have already received. We feel that this is one investment in our house that will really pay off because with the Interlock roof there is no worry about how long it is going to last. The quality of this product and the professional way in which it was installed proves that this is a company that cares about its customers.

We have seen other homes in our area getting new roofs and dreaded the mess that came with this type of work. One home even had what we called “the loan roofer” doing the job. One man doing not only to tear down of the roof but the installation of the new roof. And this was in poor weather when it was vital to get that roof on quickly. But with Interlock we had at least 5 to 6 men on the job daily, working long hours. Our property was covered so that nothing got damaged during the teardown and every scrap was picked up and removed by the workers.

We highly recommend your company and are very satisfied with the professional manner of your employees. With our Interlock roof, we have the security of knowing that this product is completely guaranteed.

Chicago, IL — Roof Review — Stunning red hidden tile aluminum Interlock roof

Stunning red hidden tile aluminum Interlock roof

Chicago, Illinois


I wanted to write and thank you for all your efforts in working with us to put in Interlock roof on our home. It was a big decision and all during the process, I felt like you really had our interests at heart. You never tired of answering my questions and your follow-up, whenever I needed to speak with you, was first rate.

I think we had three Interlock crews involved in our project. First came the tear-off guys, who, in our case, had to remove a cedar shake roof before any other improvements could take place. Second, came the install crew, led by “Nacho”, who is absolutely terrific to work with. Ours was a relatively complicated job, with lots of angles, overhangs, gables and pitch to deal with. Nacho made it happen. Finally, the cleanup crew. When Interlock left the job site, my expectations were exceeded. No landscaping was damaged and the debris was all cleared away.

Now, we have a stunning red hidden tile aluminum Interlock roof to look at and enjoy. Perhaps most enjoyable is knowing there will never need to be another roof put on this house. Already, after just a few weeks, we have received numerous compliments from neighbors and friends and see a lot of people slowing in their cars to get a better look.

Bob, thanks to you and all the Interlock staff again for your assistance in making this experience a positive one.

Orland Park, IL — Roof Review — Clever and unique interlocking design

Clever and unique interlocking design

Orland Park, Illinois


Now that our new Interlock Roofing system has been installed, we find the look to be extraordinary! It boasts sophistication and looks clean and elegant. This product is impressive not only by its looks but also by its clever and unique interlocking design.

Almost more important than the attractive look of our new roof, is the peace of mind we have gained with its many features. It’s a relief not to have to be concerned about losing shingles as a result of the high winds we experience regularly in our area. Also having experienced ice dams this past winter, it is reassuring to know that they cannot occur with the design of this product. We are impressed with its many features and in addition to the two already mentioned, the inability of the shingles to curl, being fireproof and the reflective properties are features that caught our attention. Knowing the product is guaranteed to last a lifetime and never having to re-roof is an added bonus.

The installation of our new roof began four weeks after the materials have been delivered, and then took another four full weeks to complete the actual installation process. Although hampered by a couple of days of strong winds and a couple more of rain, Eric, our installer did an awesome job of handling our installation. He was very professional and personable at all times and was willing to answer and explain our questions. Eric is obviously very skilled at his profession and pays attention to detail, which contributed greatly to the outcome of our new roof.

We would recommend this roofing system to anyone wanting to improve the look and value of their home, but would also cautioned him about the lengthy installation process and the inaccurate scheduling information we received. We believe this to be an outstanding product despite these problems.
