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.

The roof is gorgeous, best money ever spent. Chuck was great at explaining the system. Allen was a true pleasure to work with and there are no words to describe the excellent job Jesse and his wonderful crew did. I am truly impressed beyond belief with Interlock.

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 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: 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.

Review: November 28, 2022Completion: November 23, 2022

Interlock Metal Roofing is an amazing company to do business with. My salesperson John was professional and knowledgeable. It is a big investment, but absolutely worth it. The installation crew was on time, hardworking and conscientious. I highly recommend this company to anyone who wants a roof to last 100 years!

Review: January 9, 2023Completion: December 22, 2022

I love the outcome of the roof. It is absolutely beautiful. They were professional when they did the install. They don't need to improve. They are doing an excellent job.

Review: August 11, 2022Completion: June 14, 2022

I just want to say the Interlock team did an excellent job installing my roof. The installation team were craftsman, cordial, punctual, and they did a great job of keeping the work site clean at the end of each day. As far as the roof I love the look of the black standing seam with the dark gray Hardie Board siding, and I can already tell that the roof is keeping my house and garage cooler.

Review: October 12, 2020Completion: September 30, 2020

Jesse was very professional and knowledgeable about the product. He answered any questions we had about the roof. It all went great! They could have kept me updated instead of me having to continually call for updates. They could have gave me a status but they didn't.

★★★★★
Review: November 29, 2023Completion: October 5, 2023

I'm really excited and pleased with the roof. I love everything about it in terms of color, style, and installation. Everything was done to our utmost satisfaction. Interlock Roofing could have improved the price. The price was expensive. It was a fantastic experience.

★★★★★
Review: June 21, 2017Completion: May 12, 2017

Areas where flashing needs to extend beyond a vertical surface i.e. chimney's, second story corners, you need a method to provide a more professional look when making cuts in aluminum siding. Happy with my decision to purchase a roof from Interlock. It looks great. Time will tell if it will perform as promised.

★★★★★
Review: July 14, 2021Completion: June 21, 2021

Communication could have been better prior to the project starting. They communicated wonderfully until we paid our down payment. Then communication ceased. There was no communication until we reached out to them expressing our concerns. Once the project started communication was phenomenal. The roof looks extraordinary. We have had some heavy rain and our roof has held up wonderfully and it is beautiful. We believe it is a better quality than others.

Metal Roofing FAQs for Homeowners in Cherry Valley

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

Will metal roofing handle Boone County's freeze-thaw cycles without cracking?

Yes—aluminum roofing is immune to the freeze-thaw damage that degrades asphalt and wood. Cherry Valley experiences about 81 freeze-thaw days per year, where moisture trapped in traditional materials expands and contracts, causing splits and deterioration. Interlock's roofing-grade 3105-H24 aluminum alloy doesn't absorb water, so ice formation poses no structural threat. The four-way interlocking panels also accommodate thermal expansion without stress, and the Alunar 70% PVDF coating (warranted 30 years against degradation per ASTM D4214) resists the salt-laden freeze cycles common to northern Illinois. You're buying durability, not a recurring repair cycle.

How does metal roofing perform under Cherry Valley's snow load?

Interlock metal roofing sheds snow cleanly because its smooth, interlocked panels create a unified surface that prevents ice dams—a critical advantage in a climate averaging about 71 cm of snow annually. The light weight of the aluminum (the Shake profile weighs only 0.58 lb/sq ft) means no structural reinforcement is required, even when heavy snow accumulates. Unlike asphalt shingles, which absorb moisture and add weight, or slate, which requires expensive framing upgrades, Interlock installs directly over most existing roofs. Snow guards can be added if desired for architectural or safety reasons, and the panels' interlocking geometry prevents water seepage during the thaw cycles typical of Illinois winters.

Can metal roofing stand up to Illinois wind gusts?

Interlock's four-way interlocking aluminum panels are warranted to withstand wind speeds up to 120 mph—well above the typical gusts of 98 km/h (about 61 mph) recorded in Cherry Valley. The mechanical interlock creates redundant load paths so that even during severe weather, panels stay fastened and sealed. This engineering is validated by ICC-ES evaluation report ESR-1790 (reissued 2025 for IBC/IRC compliance), which confirms installation-to-spec performance in high-wind zones. Combined with the light weight of aluminum—about 96% lighter than concrete tile—there's less sail area for wind to grip, making the roof more aerodynamic than heavy traditional materials. Your home's framing bears less stress, and your insurance may recognize the superior wind resistance.

Does Interlock roofing qualify for hail damage coverage or insurance breaks?

Interlock carries a UL 2218 Class 4 impact rating—the highest available—and the Guardian Warranty even covers perforation from hailstones up to 1.5 inches. Many homeowners in hail-prone regions find this credential alone justifies a conversation with their insurer about lower premiums. Class 4 means the roof has been tested to withstand impacts that would puncture or crack asphalt, wood, or standard metal roofing. Illinois experiences occasional severe hail, and the non-combustible, Class A fire-rated aluminum panels (ICC-ES ESR-1790) also appeal to underwriters evaluating risk. Document this rating in your homeowner's policy renewal and ask your agent about impact-resistance discounts; the specification is recognized nationwide.

Why does aluminum roofing resist rust where steel fails?

Aluminum cannot rust because it contains no iron—only the roofing-grade 3105-H24 and 3003-H24 aluminum alloys (ASTM B209) that form a self-healing oxide layer when exposed to air. Even if scratched during installation or storms, the oxide reforms automatically and protects the underlying metal. Cherry Valley's annual rainfall of about 853 mm and seasonal snow melt provide plenty of moisture, which would accelerate rust in steel roofing, but aluminum merely oxidizes to an inert gray patina that actually strengthens the surface. The Alunar 70% PVDF fluorocarbon finish (applied to both sides of each panel) adds a 30-year coating warranty against fading and chalking, so you're protected from both environmental corrosion and UV degradation. This is why Interlock roofs perform equally well from coastal salt-air homes to inland Midwest climates—the material simply doesn't corrode.

How much upkeep does a metal roof require compared to asphalt shingles?

Metal roofing requires far less maintenance than asphalt or wood. Asphalt shingles deteriorate over 15–20 years, losing granules and curling in UV exposure; wood shingles split and rot under freeze-thaw stress (Cherry Valley sees 81 such cycles annually) and demand regular treatment. Interlock aluminum needs only occasional gutter cleaning and inspection—no sealing, no re-coating, no granule replacement. The Alunar 70% PVDF coating is CALGreen-verified for reduced maintenance, and because aluminum is non-porous, algae and moss growth is minimal even in damp Illinois springs. The four-way interlocking panels are self-draining, so water doesn't pool and debris doesn't accumulate. You'll save thousands over 50+ years in avoided repairs, treatments, and tear-offs.

Is metal roofing worth the upfront cost over the life of the roof?

When you calculate total cost of ownership—material, installation, maintenance, energy, and replacement cycles—Interlock is the last roof you buy. Asphalt shingles cost less upfront but require replacement every 15–20 years; over 50 years, you'll buy and install asphalt 2–3 times. Metal roofing's lifetime limited warranty (non-prorated for the original owner, transferable for 50 years to the next owner) means one installation lasts as long as your home. Add energy savings from energy-efficient colors with solar reflectance up to 0.55, which reduce cooling loads in summer and reflect heat that about 3087 annual sunshine hours would otherwise absorb. The Guardian Warranty covers rusting, rotting, splitting, and loss of impact resistance—risks that drive repeated repairs on traditional roofs. Homeowners who plan to stay 10+ years almost always recoup the difference.

Can a metal roof actually help lower cooling costs in Illinois summers?

Yes. Interlock's energy-efficient colors achieve thermal emissivity of 0.84 and initial solar reflectance up to 0.55 (measured per energy-efficiency and Cool Roof Rating Council standards), meaning they bounce sunlight back into the atmosphere rather than absorbing it into your attic. Over about 3087 annual sunshine hours, this reflection compounds into measurable cooling savings, especially during the warm season. Darker asphalt shingles absorb nearly all solar energy and transfer heat into your home, forcing air conditioning to work harder. Metal roofing's reflective surface keeps the roof surface itself cooler, reducing the temperature differential that drives heat gain through the ceiling. The effect is modest in a climate as cool as Cherry Valley's (mean of 10.2°C annually), but it's real—and in a northern home, you're not sacrificing winter heat retention, because the metal conducts no differently than asphalt. Energy efficiency is a bonus, not the main benefit here.

Can new metal roofing be installed over my existing asphalt roof?

Yes—one of metal roofing's greatest advantages is that it installs directly over most existing asphalt shingles, eliminating the cost and landfill impact of tear-off. Interlock panels are extraordinarily light: the Mediterranean Tile profile weighs only about 0.59 lb/sq ft, and the Shake about 0.58 lb/sq ft—roughly 96% lighter than concrete or clay tile. This means no structural reinforcement is needed. The installation process involves fastening the interlocking aluminum panels to the existing roof substrate, using flashing and underlayment to ensure water-tightness, and sealing all penetrations. ICC-ES evaluation report ESR-1790 confirms this over-roof installation method meets IBC/IRC code, and the job typically takes 1–3 days depending on roof size. Your existing roof becomes a built-in thermal break and sound dampener, giving you a quiet, energy-efficient result without demolition costs or contractor delays.

Is metal roofing actually better for the environment than asphalt shingles?

Fundamentally, yes. Interlock aluminum roofing is approximately 95% recyclable at end of life, versus asphalt shingles, which end the tear-off-and-landfill cycle every 15–20 years. Over 50 years, a typical home generates multiple roofing tear-offs destined for landfill; metal roofing breaks that pattern entirely. The aluminum is roofing-grade 3105-H24 and 3003-H24 alloy (ASTM B209), engineered for durability, not planned obsolescence. Because installation often occurs over the existing roof (avoiding demolition waste), you're also reducing the carbon footprint of removal, transport, and disposal. Additionally, the published solar-reflectance listing and Cool Roof Rating Council validation mean the roof's reflectivity reduces urban heat island effect and cooling energy demand across the region. CALGreen verification for reduced maintenance further cuts the environmental cost of repairs and replacements. Choosing a 50-year metal roof over serial 15-year asphalt replacements is one of the highest-impact sustainability decisions a homeowner can make.

Is a metal roof a good choice for Cherry Valley’s climate?

Yes. Cherry Valley averages about 71 cm of snow, 853 mm of rain, roughly 81 freeze–thaw days a year, with peak wind gusts near 98 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.
