Interlock® Aluminum Roofing — all-climates performance specs for Caledonia Township, 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 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.
