Review: March 3, 2022Completion: November 10, 2021

The Interlock team was a pleasure to work with from beginning to end. Undertaking the re-roof of a 108-year-old home is a major process and investment. After speaking to many other roofers, we realized that Interlock offered the best value proposition, and we felt like they were going to be able to deliver on what they promised. Our salesperson, John Mondschean displayed his extensive experience in roofing by taking the time to listen to our goals, preferences and concerns, offering solutions and working with us to achieve the desired outcome. John was responsive to every request and stuck with us even after the contract was signed. We appreciated that he was always available to answer questions, give us updates and even bring color samples over one afternoon for us to double-check our selection. John embodies integrity and service. We were aware that due to current market conditions, we might have to wait a while for our materials to be delivered; however, Interlock exceeded our expectations and was able to get the materials to us a touch earlier than promised and started the installation within three days after delivery. The day the materials were delivered, we met Jesse, the lead installer who we worked with throughout the project. Jesse was awesome in explaining all the steps to the re-roof and answering our questions along the way. He took lots of pictures for us and explained how he would address our specific concerns like adding ventilation, condition of the chimney, placement of snow guards and ensuring that the construction didn’t negatively impact our neighbors. It was clear that Jesse has been installing Interlock roofing for a long time and is a true craftsman who takes pride in the quality of his work. Jesse and his crew went above and beyond to ensure that our neighbors landscaping, A/C units and other areas were properly protected. They also ensured that our property was well protected throughout, cleaned up every day and that they left the job site in great condition once the work was finished. We give the crew excellent ratings for the overall job they did on our new roof. We are very happy with the new roof and have recommended Interlock Roofing to several of our friends and neighbors. It is awesome to have everyone on the block comment on how nice the new roof looks. It really has improved our home’s durability, value and curb appeal. We would work with John, Jesse and the entire team again! They delivered on what they promised!

Review: January 25, 2016Completion: December 30, 2016

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 well-managed and professionally carried out. I look forward to the second phase of our project in the fall.

Review: June 7, 2004Completion: June 30, 2004

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. 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 have to re-roof is an added bonus. The installation of our new roof began four weeks after the materials had 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 caution him about the lengthy installation process and the inaccurate scheduling information we received. We believe this to be an outstanding product despite these problems.

Review: November 7, 2019Completion: August 20, 2019

Dear John, We were in the market and knew we wanted a metal roof. I came across Interlock while doing some research and contacted them immediately. While it is on the pricey side, knowing that this roof will last a lifetime is very comforting. At the time of this review, we’ve only had it for a week. The weather hasn’t been terribly hot to determine if it's cooler. Other than that, the roof looks exceptional! Plenty of materials for the roof were delivered a day prior to installation, and quite a few materials were even left over. The existing roof didn’t require removal before installation, which made it possible to install over it and complete it in five days. There was a rainstorm one of the days; otherwise, they would’ve completed the installation in four days. The three-man crew (Salvador, Esteban & Humberto) were very courteous, knowledgeable professionals and took pride in their work. Under the supervision of Jesse and the young man (Benjamin), cleaning up the area made the installation run quickly and smoothly. The entire team was a pleasure to work with!

Review: March 16, 2021Completion: September 9, 2020

Last summer I realized I was in the need of a new roof on my old home which was built in 1876. I was hoping I could find a roof that accentuated the uniqueness and beauty of my old farm-style house. I always dreamed of owning a home with a metal roof, so I thought, well, let’s give this a look and see if it is an option. After searching for roofers and making some calls I found no one in my area offering metal roofs, needless to say, I became discouraged. Then, one day, on Facebook, I happened to see an ad with Midwest Roofing/Interlock Roofing showing the exact type of roof I was looking for!! I was so excited and called the number and was able to have an appointment arranged that very weekend. John came out, did some measuring, got up in my attic, then we sat and had a long, very informative discussion. John was extremely patient with my numerous questions and was able to explain things to me in layman’s terms, as I am not adept in the construction business, at all. So, the nitty gritty…I was originally thinking standing seam going into this whole project but then out came the slate look and oh my, that was it…The roof I had been looking for. It was exactly what needed to be on top of my house!!! And the black color just spoke to me…. John agreed!! Nowhere else had I ever seen a roof like the one I was about to have put on my beloved home. So, the price, while I knew a metal roof was going to cost more, I was looking more for security and peace of mind. I am a single parent of a child on the autism spectrum. I knew that I did not want to deal with roof issues in the future, the struggle to get a roofer to come to fix their problem, and the thought of having to replace it all over again just a few years down the road. Nope, the extra cost of this one-and-done roof was well worth it to me…after all, how do you put a price tag on peace of mind? And there aren’t many things in this world nowadays that can give you that. So, I signed the contract… The delivery…. how exciting…all these boxes lined up in my driveway…it was getting real!! Installation begins. Never in my lifetime have I met such an amazing installation crew, headed by Jesse. These guys worked tirelessly on transforming my average-looking home into the WOW home on the block. They took great care in working around my cupola and rock chimney, making sure everything was sealed where it needed to be, even reinforcing the cupola as it had been up there for so many years. These guys are not just installers, they are truly artists, and the pride in what they do shines in their workmanship. Even the care in the cleanup was amazing…very impressed. Any company can put out an amazing product, but for that product to remain amazing, that company has to have professional team members working with the customers…that is what you will get if you go with Interlock. Not just a stand-out product but a stand-out crew from sales, scheduling, and installation…it’s the whole package.

Review: August 1, 2019Completion: July 18, 2018

Dear John, Thanks for doing such a great job on our roof! We initially found out about Interlock from looking at a neighbors roof and seeing how nice it looked. We were in the market for a roof, so we asked for a referral and then contacted Interlock. John was very knowledgeable and offered some great options. We were a bit hesitant at first for two main reasons. First, we got a little sticker shock because the price was so much higher than an average roof, and Second, because we were scared the roof would be noisy when it was raining since it was metal. For one, the price value is worth it in the end. You know you received a quality roof that will be the last roof you’ll buy on that property. Comparing it to others that you’ll almost always replace in 7-10 years, this one is worth it. It also looks much more beautiful, and as far as the noise, there really is no difference. We’re happy with how the roof looks, the installation was easy, all crew members were courteous, and there have been zero issues with the roof. We already had it for a year when writing this testimonial, and we are still happy with our decision.

Review: June 2, 2017

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 up 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 done 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 is looking for a metal roof.

Review: August 24, 2017

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, but 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 was 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.

Review: May 11, 2017

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 with 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 the 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 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 the 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, led 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.

Review: November 26, 2013Completion: November 9, 2013

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. 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. 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. 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. 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.

Review: May 10, 2021Completion: May 3, 2021

The process was seamless, it was a no-headache, no-hassle experience and the roof looks amazing. The team was fast, respectful, and really took the time to make sure we understood everything that was going on. They were very safe and considerate of my dogs going in and out of the backyard, and took extra time to clean up everything each day, and especially when they finished the job. And not a single plant damaged (which is amazing, because they are planted right up next to the house)! They were friendly and communicative, and took care of everything. It was a great experience, and we now have the most beautiful roof on the block. I think the scheduling team could have been a little bit more proactive in terms of communication in the time between the signing of the contract and the installation, but obviously it all worked out just fine, so they clearly were doing everything they needed to be doing scheduling-wise, and it ultimately didn't influence the experience all that much, especially since John Mondschean (sales) was so accommodating and communicative throughout the process. There have been a lot of new roofs going on in my neighborhood since the big double hailstorm last year, and I can confidently say that ours is the most beautiful, and the team that installed it was the cleanest and most considerate. There was not a single piece of plastic, nail, etc. left behind after they were done, and they were pretty quiet throughout the process, which was important to me as I work from home.

Metal Roofing FAQs for Homeowners in Caledonia Township

The following metal roofing FAQs are designed specifically for homeowners in Caledonia Township, Illinois. 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 Caledonia Township.

How does a metal roof handle Caledonia's snow and ice buildup?

Metal roofs shed snow more readily than asphalt because the smooth, hard surface doesn't trap moisture the way granules do—and with about 81 centimeters of snow per year here, that matters. The four-way interlocking panels bond so tightly that ice can't work its way underneath, which is critical during the roughly 85 freeze-thaw cycles Caledonia sees annually. Add snow guards if you want to control where the snow exits, and you'll never have to worry about ice dams rotting your fascia or gutters the way asphalt roofs do in this climate.

Why does freeze-thaw damage asphalt roofs but not aluminum?

Asphalt absorbs moisture—when water freezes and expands inside it during Caledonia's 85 freeze-thaw days annually, the material cracks and curls. Aluminum is inert and doesn't absorb water, so freezing and thawing can't damage the substrate. The 3105-H24 aluminum alloy used in Interlock panels contains zero iron, which means there's no corrosion pathway, and the oxide layer that forms on aluminum actually self-heals when scratched. After 120+ years of freeze-thaw data from other cold climates, aluminum roofs outlast everything else in these conditions.

Is metal roofing prone to rust in a Midwest climate?

Aluminum cannot rust because it contains no iron—rust requires iron oxide. Interlock roofing uses roofing-grade 3105-H24 aluminum alloy, and even when the aluminum surface is scratched, it forms a new oxide layer automatically within hours. The Alunar 70% PVDF fluorocarbon coating is applied to both sides of the panel, offering an extra layer of protection. With about 863 millimeters of annual rainfall here, that dual-sided coating (warranted 30 years against chalking and fading) is insurance against moisture; steel roofs would be rusting away underneath by now.

Can a metal roof handle Caledonia's wind gusts?

Yes—Interlock metal roofing is warranted to resist wind speeds up to 120 miles per hour when installed to specification, and our area typically sees gusts around 97 kilometers per hour. The four-way interlocking panels lock together on all sides, which distributes wind load across the entire roof plane instead of letting wind peel up corner panels the way it does with shingles. That mechanical grip is what gives you the confidence to keep your roof through the gusty springs and winters Boone County throws at you.

Does hail damage metal roofing, and can it lower insurance costs?

UL 2218 Class 4 is the highest hail impact rating available, and Interlock panels carry it—meaning they've passed impact tests equivalent to 50-millimeter steel balls dropped from 20 feet. The warranty even covers perforation from hailstones up to 1.5 inches. Because aluminum is so light (the Shingle profile weighs just 0.41 pounds per square foot), impact energy doesn't crush it the way it does heavier materials—it flexes and absorbs the blow. Many insurers offer discounts on premiums for Class 4 roofing; check with yours about how this rating translates to your policy.

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

No. The Interlock Mediterranean Tile profile installs at just 0.59 pounds per square foot—roughly 96% lighter than real clay or concrete tile—so your existing framing handles it without any upgrades. You can even install metal roofing directly over your existing asphalt shingles in most cases, which saves money on tear-off and disposal. Traditional tile would require expensive structural reinforcement; aluminum gives you the look without the weight penalty, and with about 3,079 sunshine hours per year in Caledonia, that lighter roof also reflects and releases heat more efficiently than a heavy tile installation.

Will a metal roof keep my home cooler in summer?

energy-efficient colors with initial solar reflectance up to 0.55 (like Aged Copper Penny) reflect sunlight that asphalt absorbs and converts to heat. The thermal emissivity of 0.84 means the roof radiates absorbed heat back out efficiently, rather than storing it. With about 3,079 sunshine hours annually in this region, a reflective metal roof can noticeably reduce air-conditioning load. The cooler roof surface also extends the life of your cooling system by reducing cycling stress—a real win over the long haul compared to a dark asphalt roof that heats your attic all summer.

How long does a metal roof actually last, and what does the warranty cover?

Interlock carries The Guardian lifetime limited, non-prorated material warranty for the original owner, covering rusting, rotting, splitting, cracking, curling, and loss of impact resistance. It's also one-time transferable, which means the next owner gets 50 years of coverage from completion—a major resale advantage. The aluminum substrate won't degrade in your lifetime, the Alunar coating is warranted 30 years against fading, and the engineering behind the four-way interlock has been proven since 1998 across climates from coastal salt-air homes to Antarctica. That's the last roof you'll buy.

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

Metal roofing requires virtually no maintenance. Unlike asphalt shingles (which lose granules and deteriorate), wood shakes (which split and rot, especially in Caledonia's 85 annual freeze-thaw cycles), or clay tile (which requires regular regrouting), aluminum panels don't degrade, splinter, or leak at seams. You don't pressure-wash it, don't replace fasteners, and don't apply sealant every few years. Rain and snow clean it naturally. The CALGreen-verified reduced-maintenance profile means lower long-term cost of ownership and zero surprise repairs—that peace of mind alone is worth the initial investment.

Is metal roofing worth the upfront cost versus asphalt shingles?

Upfront, metal costs more; over the roof's life, it's far cheaper. An asphalt roof lasts 15–20 years in this climate and then gets torn off and sent to a landfill—and you'll do that twice before a metal roof ever wears out. With roughly 863 millimeters of rain and 81 centimeters of snow annually, asphalt fails faster here due to moisture absorption and freeze-thaw damage. Interlock's lifetime warranty, zero maintenance, no tear-offs, and one-time transferable 50-year term for the next owner mean you're paying once and never again. Factor in potential insurance discounts for Class A fire rating and UL 2218 Class 4 hail resistance, and the math shifts decisively in metal's favor over 40+ years.

Is a metal roof a good choice for Caledonia Township’s climate?

Yes. Caledonia Township averages about 81 cm of snow, 863 mm of rain, roughly 85 freeze–thaw days a year, with peak wind gusts near 97 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.
