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.

Review: December 19, 2014

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 Avondale

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

Will a metal roof handle Avondale's freeze-thaw cycles without damage?

Yes—aluminum expands and contracts with temperature swings, but its non-corrosive nature means it won't crack or degrade like asphalt or wood shingles do. Cook County experiences about 69 freeze-thaw days annually, a cycle that degrades traditional materials. Interlock's 3105-H24 aluminum alloy maintains structural integrity through repeated freezing; the self-healing oxide layer prevents any microscopic damage from becoming corrosion. Combined with the solid deck and underlayment installation method, you're protected against the seasonal stress that shortens asphalt roof life by years.

How does Interlock handle the 73 cm of snow Avondale gets each winter?

Interlock metal roofing sheds snow naturally due to its smooth, sloped profile and lightweight construction, which means your home's frame isn't strained by accumulation. At roughly 0.41 to 0.59 lb/sq ft depending on profile, even heavy snow loads pose no structural concern—a concrete tile roof weighs about 96% more. The four-way interlocking seams prevent water infiltration if ice dams form, and optional snow guards can be installed to control shedding safely. Your roof will handle Avondale winters without the maintenance burden of clearing asphalt shingles or the risk of ice backup damage.

Are four-way interlocking panels strong enough for Cook County's wind gusts?

Yes—Interlock's interlocking system is warranted to resist wind speeds up to 120 mph, well above Avondale's typical gust peak of 95 km/h (59 mph). The four-way interlocking design means each panel locks to its neighbors in all directions, distributing wind load across the entire roof assembly rather than relying on fasteners alone. This engineering, combined with ICC-ES evaluation report ESR-1790 compliance, gives you assurance that seasonal storms and occasional gusts won't lift or separate panels. The warranty covers wind resistance when installed to specification—a level of protection asphalt shingles simply cannot match.

Does a metal roof help with insurance or hail damage claims?

Interlock achieves UL 2218 Class 4 impact rating—the highest available—and the Guardian Warranty even covers perforation from hailstones up to 1.5 inches. Many insurance carriers recognize this non-combustible aluminum construction and Class A fire rating as risk reducers and may offer premium discounts; contact your agent with the product specs. Unlike asphalt, which dents and degrades under hail impact, aluminum's hardness and flexibility mean it absorbs impact without permanent loss of performance. For homeowners in Cook County facing occasional severe weather, this rating translates to fewer claim hassles and longer-term cost savings.

Can aluminum roofing rust in Avondale's wet climate?

Aluminum cannot rust because it contains no iron—the element that creates rust in steel. Instead, aluminum naturally forms a protective oxide layer that self-heals when scratched, keeping moisture away from the metal itself. Avondale's 1024 mm annual rainfall and freeze-thaw cycle would accelerate rust in steel roofs, but Interlock's roofing-grade 3105-H24 and 3003-H24 aluminum alloy (ASTM B209) stays intact indefinitely. The Alunar® 70% PVDF fluorocarbon finish, warranted 30 years against chalking and fading, adds a second protective barrier applied to both panel sides. This dual protection means your roof won't corrode, weaken, or require rust-prevention maintenance.

Do I need to reinforce my home's structure for a metal roof?

No reinforcement needed. Interlock's Tile profile weighs about 96% less than concrete or clay tile—roughly 0.59 lb/sq ft—so it installs safely over most existing roof structures without modification. This lightweight advantage matters in older Avondale homes where heavy slate or tile would require costly structural work. Because panels are so light, installation happens faster, labor costs stay reasonable, and you can often re-roof directly over your existing asphalt without tearing it off. The four-way interlocking system distributes weight evenly, and ICC-ES ESR-1790 confirms compliance with IBC and IRC structural codes for your region.

How much maintenance does an Interlock metal roof really need?

Virtually none compared to asphalt, wood, or tile. Aluminum doesn't rot, split, curl, or degrade—the self-healing oxide layer handles UV exposure and moisture year-round. Avondale's 3094 annual sunshine hours won't fade your roof thanks to the 30-year Alunar® PVDF coating warranty (tested to ASTM D4214 and D2244 standards). You won't need to clear moss, replace damaged shingles, or seal cracks. Annual inspection for debris is optional; light rain handles cleaning automatically. CALGreen verification confirms reduced maintenance requirements compared to traditional roofing. This means lower upkeep costs and genuine peace of mind over decades.

Will an Interlock roof keep my home cooler in summer?

Yes—energy-efficient colors reflect heat that asphalt absorbs, lowering cooling costs. Interlock's thermal emissivity reaches 0.84, and initial solar reflectance can reach 0.55 in select finishes like Aged Copper Penny, both Cool Roof Rating Council verified. While Avondale averages only about 3094 sunshine hours annually, those high-intensity summer days still generate significant cooling demand; a reflective roof directly reduces air-conditioning runtime and expense. The lightweight aluminum panel won't add heat mass to your attic the way concrete tile does. Over a 30+ year roof life, energy savings compound into thousands of dollars, plus the satisfaction of lower carbon emissions.

What makes the Guardian Warranty different from typical roof warranties?

The Guardian Warranty is lifetime limited and non-prorated for the original owner—meaning you're covered for rusting, rotting, splitting, cracking, curling, and loss of impact resistance with no dollar or time limit, no deductible step-down. It's transferable once to the next owner for 50 years from completion, which adds real resale value. Most asphalt warranties are prorated (coverage decreases yearly), and cedar or slate warranties cover only specific defects. Interlock's promise reflects the product's durability: aluminum doesn't rust, doesn't rot, and manufactured since 1998 from Delta, BC to Antarctic research stations proves longevity under extreme conditions. For Avondale homeowners, this is the last roof you'll buy.

How long does installation take, and can you install over my old roof?

Installation typically completes in 2–5 days depending on roof complexity, much faster than asphalt re-roofing. Yes, Interlock installs over most existing roofs thanks to its ultralight weight—no tearoff, no landfill trip, no weeks of debris. Your roofer applies the solid deck and underlayment over the old shingles, then fastens and interlocks the new panels. This method reduces labor cost and installation disruption. For Avondale homes with asphalt roofs reaching end-of-life, covering them with Interlock eliminates the environmental impact of landfill disposal while maintaining your home's structure and timeline. The ICC-ES ESR-1790 evaluation confirms this installation method meets all regional building codes.

Is a metal roof a good choice for Avondale’s climate?

Yes. Avondale averages about 73 cm of snow, 1024 mm of rain, roughly 69 freeze–thaw days a year, with peak wind gusts near 95 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.
