Interlock® Aluminum Roofing — all-climates performance specs for Avalon Park, 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 Avalon Park
The following metal roofing FAQs are designed specifically for homeowners in Avalon Park, 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 Avalon Park.
Will a metal roof hold up through Avalon Park's freeze-thaw cycles?
Yes—aluminum's oxide layer actually strengthens when exposed to repeated freeze-thaw stress, unlike asphalt or wood that crack and curl. Avalon Park averages about 70 freeze-thaw days per year across the typical winter, and Interlock's 3105-H24 aluminum alloy (ASTM B209) expands and contracts uniformly without delaminating or splitting. The four-way interlocking panels accommodate this movement, and the 30-year Alunar fluorocarbon coating resists the salt and moisture that accelerate degradation in seasonal climates. This is why the material has been installed in Antarctic research stations—extreme thermal cycling is where aluminum proves itself.
How does metal roofing perform under Avalon Park's snow load?
Cook County receives about 68 centimeters of snow annually, and metal roofing sheds it more efficiently than asphalt because its smooth, sloped panels and interlocking seams don't trap moisture or allow ice dams to form underneath. Snow load capacity depends on your roof pitch and support structure—not on the roofing material itself, since Interlock's aluminum profiles weigh only 0.41 to 0.59 lb/sq ft. Snow guards can be added where needed. The real advantage is that snow and ice release cleanly without the freeze-thaw damage that splits asphalt shingles or causes wood shake to rot when meltwater pools in cracks.
Is a metal roof safe in Avalon Park's wind gusts?
Cook County's typical gusts reach 93 kilometers per hour, and Interlock metal roofing is warranted to resist sustained winds up to 120 mph (193 km/h) when installed to specification. The four-way interlocking system locks each panel to its neighbors on all edges, preventing uplift or separation—a vulnerability of single-fastener asphalt shingles. The UL 2218 Class 4 hail rating also confirms the structural integrity that wind resistance requires. Wind damage claims on traditional roofs spike after heavy gusts; metal roofing's mechanical interlock means your roof stays intact when others fail.
Can I get an insurance discount for a Class 4 hail-rated metal roof?
Possibly—many insurers offer premium discounts for UL 2218 Class 4 impact-rated roofing because the claims data shows fewer failures. Interlock's aluminum panels carry the Class 4 rating, the highest available, and the Guardian Warranty even covers perforation from hailstones up to 1.5 inches. Contact your agent with the UL listing to inquire about discounts; some carriers reduce premiums by 10–20% for Class 4 metal roofs in hail-prone regions. Combined with the 120-year combined lifespan (lifetime for you, 50-year transfer), this eliminates the cycle of repeated claims from asphalt deterioration.
Why don't Interlock metal roofs rust like steel roofing?
Interlock uses roofing-grade 3105-H24 / 3003-H24 aluminum alloy (ASTM B209), which contains no iron—iron is what rusts. Aluminum instead forms a thin, self-healing oxide layer that protects it from corrosion. Even if the coating scratches, the oxide reforms, making aluminum naturally corrosion-resistant in any climate, including near salt water. Cook County's average of 1042 mm annual rainfall and freeze-thaw cycles create corrosive conditions, but aluminum thrives here because the material itself cannot degrade into rust. Steel roofing requires constant coating maintenance; aluminum does not.
What does Interlock's lifetime warranty really cover, and for how long?
The Guardian Warranty is a lifetime limited, non-prorated material warranty for the original owner, covering rusting, rotting, splitting, cracking, curling, and loss of impact resistance—the failures that plague asphalt, wood, and inferior metal. It transfers once to the next owner for 50 years from completion, meaning your buyer inherits genuine protection. The Alunar coating itself carries a separate 30-year coverage against chalking and fading (ASTM D4214 / D2244 measured). No other roof material matches this combination: asphalt lasts 15–20 years before you replace it; this is your last roof.
Do I really have to maintain a metal roof less than asphalt or tile?
Yes, substantially less. Asphalt requires regular granule inspection, gutter cleaning from shed particles, and seal-coat reapplication every few years to slow deterioration. Wood shake demands annual treatment for mold and rot—especially in a climate with 70 freeze-thaw days and high moisture. Concrete and clay tile are porous and harbor algae; they need chemical cleaning. Interlock aluminum is smooth, non-porous, and self-shedding; rain and the 3025 annual sunshine hours naturally clean it. The CALGreen verification confirms reduced-maintenance performance. Gutter cleaning is your only routine task—the material itself requires nothing.
Can my house handle metal tile if it doesn't support real tile?
Yes—this is one of metal roofing's structural advantages. Interlock's Mediterranean Tile profile weighs only 0.59 lb/sq ft, making it about 96% lighter than concrete or clay tile. Your existing roof framing, which may not tolerate the 800–1000 lb/sq ft load of real tile, easily supports this aluminum alternative without reinforcement. Many homeowners install Interlock Tile directly over their asphalt shingles, spreading the cost across years and avoiding costly structural upgrades. The ICC-ES ESR-1790 evaluation confirms compatibility with standard residential framing. You get the traditional tile aesthetic without the engineering costs.
Is metal roofing Class A fire-rated?
Interlock aluminum is non-combustible and available in Class A fire classification, the highest rating. Aluminum cannot burn because it contains no organic material; fire testing confirms it meets the stringent ASTM E108 requirements for Class A. This matters if your homeowner's insurance or local Cook County building code requires it, and it matters psychologically—knowing your roof won't contribute to fire spread. The ICC-ES ESR-1790 evaluation report documents this performance. If your current asphalt roof is Class C or unrated, upgrading to Class A metal reduces risk and may lower insurance premiums depending on your carrier's underwriting.
Is metal roofing worth the higher upfront cost over asphalt in Cook County?
Calculate the lifetime cost, not just the first bill. Asphalt costs less initially but lasts 15–20 years in your climate's 68 cm annual snow, 70 freeze-thaw days, and 1042 mm rainfall—all accelerants of shingle failure. You'll replace it twice before an Interlock roof reaches 50 years. Metal costs 2–3x more upfront but requires no replacement, no coating renewal, no seasonal repairs, and minimal maintenance for a century. Add the 50-year transferable warranty (doubling your home's future value), zero asphalt tear-off waste, and potential insurance discounts on Class 4 hail-rated panels—the total cost of ownership heavily favors metal. You're comparing a 20-year expense cycle to a permanent investment.
Is a metal roof a good choice for Avalon Park’s climate?
Yes. Avalon Park 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.
