Interlock® Aluminum Roofing — all-climates performance specs for Bonus 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 Bonus Township
The following metal roofing FAQs are designed specifically for homeowners in Bonus 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 Bonus Township.
Does a metal roof handle Bonus Township's heavy snow and freeze-thaw cycles?
Yes—Interlock's aluminum panels shed snow and ice far more effectively than asphalt. With about 81 cm of snow falling annually in this region and roughly 85 freeze-thaw days per year, the smooth, slippery metal surface prevents ice damming and reduces the freeze-thaw stress that cracks traditional shingles. The four-way interlocking design also resists uplift from wind gusts reaching 97 km/h, so snow loads stay secure. Aluminum's oxide layer won't degrade under repeated moisture cycles the way asphalt does.
Can aluminum metal roofing rust in a cold climate with snow melt and rain?
No. Aluminum cannot rust because it contains no iron. When exposed to moisture, aluminum forms a self-healing oxide layer that protects the metal beneath—even when scratched. The roofing-grade 3105-H24 and 3003-H24 alloy (ASTM B209) paired with a 30-year-warranted Alunar 70% PVDF coating on both panel sides ensures durability through Bonus Township's 863 mm annual rainfall and wet freeze-thaw cycles. This dual protection is especially critical here, where freeze-thaw days number about 85 per year.
Is a metal roof too heavy to install on an older home in Bonus Township?
The opposite. Interlock panels weigh extraordinarily little—the Shake profile installs at just 0.58 lb/sq ft, and the Mediterranean Tile at 0.59 lb/sq ft, making it about 96% lighter than concrete or clay tile. This light weight means no structural reinforcement is required; the roof installs directly over most existing structures and existing roofs, saving time and expense. With about 81 cm of seasonal snow load expected here, the aluminum panels distribute weight far more efficiently than traditional tile, protecting your home's framing while lasting decades.
Will metal roofing stay secure during Bonus Township's wind and gust events?
Yes. The four-way interlocking aluminum panels are warranted to resist wind speeds up to 120 mph (193 km/h) when installed to specification. Bonus Township's typical gusts reach about 97 km/h, well within that range. The interlocking design locks each panel to its neighbors horizontally and vertically, creating a unified structure that resists uplift far better than fastened shingles. This engineering means your roof remains secure through the seasonal wind events typical of Boone County.
Does Interlock metal roofing qualify for hail damage insurance coverage?
Yes. Interlock panels carry a UL 2218 Class 4 impact rating—the highest available—and the Guardian Warranty explicitly covers hail perforation up to 1.5 inches. Class 4 rating meets or exceeds the impact thresholds that trigger insurance premium reductions in hail-prone regions. When you pair non-combustible aluminum construction with Class A fire rating availability and documented impact resistance, many insurers recognize the reduced claim risk. Check with your agent about potential discounts for upgrading to a roof rated this high.
How does metal roofing perform through repeated freeze-thaw cycles?
Metal roofing excels in freeze-thaw environments. Aluminum expands and contracts uniformly with temperature swings, and its oxide layer doesn't crack or degrade as asphalt does. At 85 freeze-thaw days per year in Bonus Township, this durability compounds over decades. Traditional shingles absorb moisture, freeze, crack, and curl—each cycle accelerating failure. The roofing-grade aluminum alloy with its 30-year Alunar coating resists this moisture-driven deterioration. The Guardian Warranty covers cracking, curling, and loss of impact resistance over the roof's life, meaning freeze-thaw cycles won't trigger claims.
What maintenance does an Interlock metal roof require in Bonus Township?
Virtually none compared to asphalt, wood, or tile. The aluminum panels don't rot, split, curl, or lose granules like shingles do through rain and snow cycles. With about 863 mm of annual rainfall and roughly 81 cm of snow, traditional roofs demand regular inspection, repair, and replacement of damaged sections. Interlock's CALGreen-verified design eliminates the maintenance burden. Periodic gutter cleaning and inspection of flashing are standard for any roof, but the panels themselves require no treatment, sealing, or repair—saving you money and time over the roof's lifetime.
What warranty protection comes with Interlock metal roofing?
The Guardian Warranty provides a lifetime limited, non-prorated material warranty for the original owner against rusting, rotting, splitting, cracking, curling, and loss of impact resistance. The warranty transfers once to the next owner for a 50-year term from completion, boosting resale appeal. This coverage reflects the durability of roofing-grade aluminum (ASTM B209) paired with the 30-year Alunar fluorocarbon coating. Unlike asphalt shingles that degrade through Bonus Township's 85 annual freeze-thaw cycles and 3,079 sunshine hours, aluminum doesn't deteriorate—the warranty simply acknowledges that reality.
Can Interlock metal roofing install over my existing roof without removal?
Yes. Because Interlock panels weigh only 0.58–0.59 lb/sq ft (depending on profile), they install directly over most existing roofs without removal or structural reinforcement. This saves thousands in tear-off labor and landfill fees while compressing installation time. The local installer, serving the region since 2001, manages the installation process efficiently. The lightweight design works especially well in Bonus Township's climate, where about 81 cm of seasonal snow load is distributed safely across the existing structure. The process typically completes faster than tear-off-and-replace, getting you into a permanent roof sooner.
Is metal roofing more sustainable than asphalt shingles?
Interlock aluminum roofing breaks the cycle of asphalt shingles destined for landfills. The panels are approximately 95% recyclable at end-of-life, and the material itself lasts 50+ years, eliminating the tear-off every 20–25 years that plagues asphalt roofs. In Bonus Township's climate of about 863 mm rain, 81 cm snow, and 85 freeze-thaw days annually, asphalt deteriorates faster, meaning more frequent landfill waste. Aluminum doesn't rot, split, or crack under these cycles—it simply lasts and recycles. Choosing Interlock means your roof won't become landfill waste and your home won't need replacement roofs for generations.
Is a metal roof a good choice for Bonus Township’s climate?
Yes. Bonus 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.
