Interlock® Aluminum Roofing — all-climates performance specs for Calumet Heights, Illinois
| Spec / Rating | Climate / Risk Factor + What It Solves |
|---|---|
| Wind resistance: 120+ mph (193+ kph) | Extreme wind, hurricanes, storm uplift: full interlocking attachment helps prevent blow-offs, edge lifting, and panel loss in high-gust events. |
| Fire rating: Class A (with proper assembly) | Wildfire, embers, radiant heat, chimney sparks: non-combustible roof assembly provides the highest residential fire protection rating. |
| Hail resistance: UL 2218 Class 4 | Hail and impact debris: highest impact classification; resists cracking, splitting, and surface loss common with asphalt under hail strikes. |
| Snow & ice performance: interlocking, shedding profile | Heavy snow, freeze-thaw, ice dams: smooth aluminum sheds snow efficiently and the interlocking design helps block water intrusion when melt-refreeze cycles occur. (Final snow-load capacity depends on roof structure and local code.) |
| Corrosion resistance: aluminum (won’t rust) | Salt air, coastal humidity, wet climates: aluminum naturally resists rust and corrosion, reducing long-term failure risk in marine or high-moisture environments. |
| Heat / UV durability: baked-on coating system | High heat, intense sun, thermal cycling: coatings resist UV breakdown and temperature-swing fatigue, slowing fading and surface degradation. |
| Moss / algae resistance: smooth coated surface | Wet shade, organic growth: low-porosity metal surface gives moss/algae less to grip, reducing staining and maintenance. |
| Material: heavy-gauge aluminum roof profiles (Slate / Shake / Shingle / Tile / Standing Seam) | All-season structural stability: lightweight, dent-resistant metal system stays stable through large hot-cold swings and severe weather. |
| Expected lifespan: 50+ years | Long-term durability across climates: avoids re-roof cycles typical of shorter-life materials, even in high-stress environments. |
| Warranty: Lifetime-Limited, non-prorated + 50-year transferable | Lifetime protection + resale value: guarantees long-term material confidence and transfers to future owners. |

What our customers are saying:
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.
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.
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.
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.
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!
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.
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.
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.
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.
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.
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 Calumet Heights
The following metal roofing FAQs are designed specifically for homeowners in Calumet Heights, 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 Calumet Heights.
How does a metal roof handle the snow and ice we get in Cook County?
Calumet Heights averages about 68 cm of snow annually, and metal roofs shed snow faster than asphalt because the smooth, hard surface doesn't hold it the way granules do. The four-way interlocking aluminum panels are warranted to 120 mph wind—more than triple the typical gusts here—so the weight of snow load isn't a structural concern. You can add snow guards if you want controlled shedding. The real benefit: ice dams form less often on metal because heat loss through the roof is even, and if they do form, the hard surface won't degrade from the freeze-thaw cycling we see about 70 days a year.
Will a metal roof crack or fail from freeze-thaw cycles?
No—aluminum's oxide layer actually self-heals when exposed to moisture, which is the opposite problem that kills asphalt and wood shingles over Calumet Heights' roughly 70 annual freeze-thaw days. The Alunar 70% PVDF coating is engineered to flex without cracking across that temperature swing. The Guardian Warranty covers cracking and splitting for life on the original owner, and the 30-year coating warranty against chalking is backed by ASTM D4214 testing, meaning the finish stays intact through decades of thaw-refreeze stress. Aluminum simply doesn't absorb water the way composite materials do, so ice expansion can't compromise it.
With all the rain Calumet Heights gets, how watertight is a metal roof?
The four-way interlocking aluminum panels shed water by design—each profile overlaps its neighbors in four directions so water runs off immediately, without pooling. At roughly 1,042 mm of annual rainfall, that redundancy matters. Installation happens over a solid deck and underlayment (just like asphalt), which is the actual water barrier; the metal acts as a hard, non-degrading second line. The panels are warranted against leaks when installed to specification per ICC-ES ESR-1790. Because aluminum never rots or swells, the seal integrity doesn't degrade over time the way wooden or composite decking can, so a properly installed metal roof stays as tight at year 25 as day one.
Does a metal roof hold up to hail, and will my insurance company care?
Interlock's profiles carry UL 2218 Class 4 impact rating—the highest available—and the warranty covers perforation from hailstones up to 1.5 inches. That's the threshold insurance companies use to assess damage risk, and many carriers offer discounts for Class 4 roofs because claims are so rare. Aluminum won't dent permanently like steel; it flexes and rebounds. In Cook County's climate, violent hail is rarer than freeze-thaw stress, but when it happens, the combination of aluminum's impact resistance and the non-prorated lifetime material warranty means you're covered either way. Contact your agent with the UL rating—it's the credential they recognize.
Can a metal roof handle the wind gusts we see here?
Calumet Heights experiences typical daily winds around 25 km/h, with gusts reaching 93 km/h, and Interlock's four-way interlocking panels are warranted to resist 120 mph (193 km/h) wind when installed to specification. That 2-to-1 safety margin above local extremes reflects the engineering: each panel locks into its neighbors on all four sides, distributing uplift forces across the whole roof rather than relying on nails alone. The ICC-ES evaluation report ESR-1790 documents this performance under IBC/IRC standards. You're not betting on a single fastener or overlap; the interlocking system is what makes wind resistance real, not marketing language.
Do I need to reinforce my house to support a metal roof?
No structural reinforcement needed. The Interlock Tile profile weighs about 0.59 lb/sq ft—roughly 96% lighter than concrete or clay tile—so it installs directly over most existing roofs without additional framing. Even the heavier Shake profile comes in around 0.58 lb/sq ft, a fraction of what traditional tile weighs. This matters in Calumet Heights because older homes with century-old joists can simply accept the new roof without carpentry. The aluminum's light weight also means faster installation and lower labor costs. ICC-ES ESR-1790 confirms installation methods over various existing structures, so your framing inspector will see a proven, code-compliant assembly.
What's the real long-term cost of a metal roof versus replacing asphalt every 15–20 years?
Asphalt roofs in Calumet Heights typically last 15–20 years in climates with about 70 freeze-thaw cycles annually and 68 cm of snow, because ice, UV, and thermal stress degrade granules faster than in gentler regions. Each replacement means tear-off labor and landfill fees. Interlock's lifetime limited material warranty (non-prorated for the original owner, transferable for 50 years to the next) means you buy once. The Alunar coating carries a separate 30-year warranty against chalking, so your initial cost is offset by zero replacements, zero tear-offs, zero maintenance. Over 50 years, that's three or four asphalt cycles versus one metal roof—labor and disposal saved, not just materials.
How much maintenance does a metal roof really need?
Essentially none compared to asphalt, wood, or ceramic tile. Aluminum doesn't rot, split, curl, or lose impact resistance—the main failure modes of competitors. CALGreen-verified for reduced maintenance, it requires no sealant reapplication, no spring inspection for loose granules, no fungicide treatments. Calumet Heights' roughly 3,025 annual sunshine hours will keep the roof bright without degrading the Alunar 70% PVDF finish (30-year warranty against fading per ASTM D2244). Rain washes it clean. The interlocking design sheds debris faster than traditional roofs, so gutters stay clearer. You inspect it once yearly like any roof, but the material itself is inert—rust-proof, rot-proof, impact-resistant for life.
Can metal roofing actually look like slate, wood shakes, or tile, or will my neighbors know it's metal?
The five profiles—Slate, Cedar Shingle, Shake, Mediterranean Tile, and Standing Seam—replicate the texture and shadow lines of their traditional counterparts through embossed detail and layered panel profiles. From street level, they visually match the materials they represent. Each profile is manufactured from the same roofing-grade 3105-H24 aluminum alloy and coated with the same Alunar finish, so you're not choosing between lookalikes; you're choosing the look that suits your home's architecture. Interlock has been producing these profiles since 1998, so the detail is refined. The choice is purely aesthetic—all five perform identically against Calumet Heights' snow, rain, and freeze-thaw cycles.
Is a metal roof actually better for the environment?
Yes, because it breaks the asphalt cycle. Traditional roofing tears off every 15–20 years and goes to landfill; Interlock panels are approximately 95% recyclable aluminum, so at end of life (decades away), the material enters a recycling stream, not waste. Over Calumet Heights' roughly 1,042 mm annual rainfall, you won't be replacing shingles or tile repeatedly, so you eliminate tear-off labor, disposal emissions, and the manufacturing carbon footprint of multiple replacements. The aluminum itself is inert and infinitely recyclable—no degradation in quality through reuse. Choosing once, 50+ years ago, and keeping that choice is the most sustainable roofing decision you can make.
Is a metal roof a good choice for Calumet Heights’s climate?
Yes. Calumet Heights averages about 68 cm of snow, 1042 mm of rain, roughly 70 freeze–thaw days a year, with peak wind gusts near 93 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.
