Review: June 17, 2019 Completion: May 31, 2019

Dear John, Several years ago, I became fascinated with the idea of a metal roof. Tired of constantly looking at my roof for signs of deterioration, I wondered if a metal roof was a realistic option for a home, as I only noticed them on barns and businesses. A few months ago, you and Mike Rasmussen visited my home to provide an estimate. I was shocked at the number of options for beautiful metal roofs that were not just functional but very attractive. Now, with the job complete – I couldn’t be more pleased. Neighbors and friends all have the same response, wondering if this is really a metal roof and commenting on how attractive it is. One of my concerns in deciding upon a new roof related to my previous experience with roofers. A twenty-year warranty for a roofing company that went out of business, asphalt shingles that began deteriorating less than ten years after installation, with manufacturers blaming the installer and the installer blaming the manufacturer, made warranties meaningless. My experience with Interlock has been excellent from beginning to end. Knowing that Interlock both manufactures and installs its roofs eliminated my concern about responsibility. A lifetime warranty (limited to 50 years when I sell my house) means I no longer have to worry about replacing my roof. It’s such a relief to know I am done with such concerns. You and Mike assured me that the installers would be meticulous and clean the area around my house every night; however, they did far more than that. I have seen many roofs installed, and it is usually a quick installation. Under the careful supervision of Jessie, the installers tediously worked to cut and detail each section. Working around the chimneys, they worked to be sure every detail was perfect, spending several hours in one small area. Preparing the areas around the eaves and valleys (not sure how to describe things) was very time-consuming as they wanted everything to be perfect. This is something else my neighbors noticed. The pride they took in their work was apparent at every turn as they answered all my questions and explained why they were doing various things. When they began working on the addition, one of the workers asked me if that room was cold in the winter and " data-wpil-keyword-link="linked">hot in the summer. I thought he was clairvoyant because it has always been the most uncomfortable room in the house. He explained there was no vent on that part of the roof, which impedes airflow. They added a vent, at no extra cost, once more, an indication of their commitment to excellence. I’m looking forward to seeing the difference in the winter – hoping I can remove the space heater. There was one young man who spent each day making sure everything was cleaned up. None of my trees, plants, or flowerpots were damaged. I’m not sure they were even touched. After each of the four days, the only indication that work was being done was the dumpster in my driveway, as everything was meticulously cleaned. Concern for the environment is very important to me, and knowing that my roof eliminates additional landfill waste is definitely an additional benefit. Thank you for living up to every promise you made when you first visited. I couldn’t be more pleased with my investment. A few neighbors who recently got new roofs were sorry they hadn’t known about how attractive, and permanent metal roofs are. A few others have said they will seriously consider metal roofs when it’s time to replace their existing roofs. So my years-long dream of a metal roof is complete; far more attractive than I ever imagined, highly functional and permanent. My only disappointment is that I anticipated listening to the rain hitting the metal roof – but it’s actually very quiet. For most, I guess that is another plus. I would be happy to answer any questions potential metal roof owners might have, as I am so pleased with my purchase (investment).

Not only was the sales process easy, the installation guys were very respectful of my neighbors and my comfort while they were working. Now that it’s done I absolutely love the roof. It’s already made a huge difference in my electric use for cooling the house!

Review: March 3, 2022 Completion: November 10, 2021

The Interlock team was a pleasure to work with from beginning to end. Undertaking the re-roof of a 108-year-old home is a major process and investment. After speaking to many other roofers, we realized that Interlock offered the best value proposition, and we felt like they were going to be able to deliver on what they promised. Our salesperson, John Mondschean displayed his extensive experience in roofing by taking the time to listen to our goals, preferences and concerns, offering solutions and working with us to achieve the desired outcome. John was responsive to every request and stuck with us even after the contract was signed. We appreciated that he was always available to answer questions, give us updates and even bring color samples over one afternoon for us to double-check our selection. John embodies integrity and service. We were aware that due to current market conditions, we might have to wait a while for our materials to be delivered; however, Interlock exceeded our expectations and was able to get the materials to us a touch earlier than promised and started the installation within three days after delivery. The day the materials were delivered, we met Jesse, the lead installer who we worked with throughout the project. Jesse was awesome in explaining all the steps to the re-roof and answering our questions along the way. He took lots of pictures for us and explained how he would address our specific concerns like adding ventilation, condition of the chimney, placement of snow guards and ensuring that the construction didn’t negatively impact our neighbors. It was clear that Jesse has been installing Interlock roofing for a long time and is a true craftsman who takes pride in the quality of his work. Jesse and his crew went above and beyond to ensure that our neighbors landscaping, A/C units and other areas were properly protected. They also ensured that our property was well protected throughout, cleaned up every day and that they left the job site in great condition once the work was finished. We give the crew excellent ratings for the overall job they did on our new roof. We are very happy with the new roof and have recommended Interlock Roofing to several of our friends and neighbors. It is awesome to have everyone on the block comment on how nice the new roof looks. It really has improved our home’s durability, value and curb appeal. We would work with John, Jesse and the entire team again! They delivered on what they promised!

Review: October 6, 2016

Dear John, I wish I had known about the Interlock Roofing System before I put the last new roof on twenty years ago. If I had, I would not have had to replace it again now. At least now I won’t need to worry about the roof ever again because of the lifetime limited warranty with its 50-year transferable and non-prorated features. When I first suggested to my wife that we consider a metal roof, she was concerned about the noise level during storms. This concern disappeared after the first storm as the noise level was much less than before the metal roof was installed. Speaking of installation, we were very happy with the way your installation crew did their job. They were careful with our landscaping and cleaned up each day and when they finished and left, the only sign of their having been there was the new roof itself. The new Interlock roof looks great, and we have been complimented on it by many neighbors as well as people passing by. Our home insurance company was also happy with the new roof and its Class 4 hail-impact-resistant rating, which will give us a discount on the insurance premium. We are very satisfied with the entire process of getting a new roof installed. From the initial discussion with the sales representative, the installation crew, and the final results, there were no surprises. We will also be very happy twenty years from now when we don’t have to put another roof on the house.

Metal Roofing FAQs for Homeowners in Hillside

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

Will a metal roof handle Hillside's freeze-thaw cycles without cracking or failing?

Yes. Aluminum expands and contracts with temperature swings, but it doesn't crack, split, or degrade from freezing like asphalt or wood shingles do. Hillside experiences about 82 freeze-thaw days per year plus roughly 73 cm of snow, creating constant stress on traditional roofs. Interlock's 3105-H24 aluminum alloy and four-way interlocking panels are engineered to flex safely through these cycles. The Alunar coating stays intact at subzero temperatures and resists the salt-laden moisture that accelerates deterioration in the Midwest. Your roof stabilizes rather than weakens year after year.

Does metal roofing cause ice dams in Chicago-area winters?

Metal roofing does not inherently cause ice dams; roof design and ventilation do. Hillside receives about 73 cm of snow annually with mean gusts around 19 km/h, so snow load and wind-driven melt are real concerns. Interlock panels install over a solid deck with underlayment that insulates as well as asphalt does, preventing the heat loss that creates dams. The smooth, slick surface actually sheds snow faster than traditional roofing once initial melt begins. Optional snow guards are available if you need to control avalanching on steep pitches. Proper attic ventilation—not the roofing material—is what prevents ice dams.

How does Interlock handle Hillside's 993 mm of annual rainfall?

The four-way interlocking aluminum panels overlap and lock on all four sides, channeling water downward and outward before it can seep into seams. With about 993 mm of rain yearly plus heavy seasonal deluges, this mechanical interlock system is far more reliable than roofing that depends on sealant or adhesive. Each panel seats firmly against its neighbors with no exposed fasteners on the weather side; water cannot pool or find entry points. Combined with proper underlayment and flashing installed to ESR-1790 code, Interlock delivers the same leak protection as asphalt but without sealant failure over time. Gutters and downspouts handle volume; the roof panels handle the water once it arrives.

Can a metal roof rust in Illinois's wet climate?

Aluminum cannot rust because it contains no iron. The moment aluminum is exposed to air, a microscopically thin oxide layer forms and self-heals even when scratched—a process that occurs invisibly and continuously. Steel roofing rusts; copper and aluminum don't. Hillside's humid Midwest climate with 993 mm rain per year would accelerate rust on steel, but aluminum thrives in it. The Alunar 70% PVDF fluorocarbon finish (applied to both sides of every panel) adds 30 years of chalking and fading resistance (ASTM D4214/D2244), giving you a durable, non-corroding roof that looks new longer. No rust means no structural compromise and no maintenance surprises.

Do I need to reinforce my house framing for a metal roof?

No structural reinforcement is required. Interlock panels are extraordinarily light—the Mediterranean Tile profile installs at approximately 0.59 lb/sq ft, about 96% lighter than concrete or clay tile. Your home's frame already supports asphalt shingles and weather loads; it easily supports aluminum. This lightweight advantage means the roof installs directly over most existing roofs without tear-off, reducing labor costs and keeping old material out of landfills. It also means you avoid the months-long delay and expense of structural upgrades that traditional tile demands. Your existing structure is adequate; Interlock simply doesn't impose the dead load penalty that stone-based materials do.

Does Interlock's hail rating actually help with insurance in Illinois?

Interlock holds a UL 2218 Class 4 impact rating—the highest available—and the Guardian Warranty covers perforation from hailstones up to 1.5 inches. Many Illinois insurers recognize Class 4 ratings and offer premium discounts or superior claim outcomes. Hail risk is real in Cook County, and a documented Class 4 rating proves your roof can absorb the impact that would dent or puncture asphalt. When you file a hail claim, underwriters see independent lab testing (Intertek listing 33876), not marketing language. Check with your agent, but homes with Class 4 roofs often secure better rates or faster settlements. The warranty also means you're protected even if insurers balk.

What makes the Guardian Warranty better than a typical 20-year roof warranty?

The Guardian is a lifetime limited, non-prorated material warranty for the original owner—covering rusting, rotting, splitting, cracking, curling, and loss of impact resistance with no step-down in coverage year to year. You never reach a point where the warranty pays less. It's also one-time transferable, giving the next owner 50 years of coverage from completion. Hillside homes see about 82 freeze-thaw cycles annually, which stress roofs relentlessly; a non-prorated warranty means you're protected through all of them. A typical 20-year asphalt warranty leaves you unprotected at year 21, while Interlock's aluminum and Alunar coating remain sound for decades. This is the last roof you buy.

How much maintenance does a metal roof need compared to asphalt or wood?

Interlock requires virtually none. Unlike asphalt shingles (which curl and lose granules in Hillside's 82 annual freeze-thaw days), or wood shakes (which rot, split, and need chemical treatment), aluminum panels don't deteriorate, degrade, or invite moss and algae growth. The Alunar 70% PVDF finish is CALGreen-verified for reduced maintenance. Gutters need cleaning like any roof, and debris should be cleared seasonally, but you won't replace shingles, repair splits, or apply treatments. The panels and coating are stable across temperature swings. You gain back the weekends and dollars you'd spend patching or replacing asphalt every 15-20 years. It's not maintenance-free, but it's maintenance-light.

How does Interlock perform in Hillside's winter storms and wind gusts?

Interlock panels are warranted to resist wind speeds up to 120 mph (193 km/h) when installed to spec. Hillside's typical gusts reach about 97 km/h, so you have a substantial safety margin. The four-way interlocking design locks panels on all four sides—horizontally and vertically—so wind cannot peel or lift corners like it can with nailed shingles. Each panel is mechanically captured by its neighbors, creating a unified system that distributes wind load across the entire roof rather than concentrating stress on fasteners. In the Midwest's spring and winter storms, this redundancy matters. Your roof stays down while asphalt shingles blow away.

Is metal roofing worth the cost over asphalt in the long run?

Metal costs more upfront than asphalt, but over a roof's life—the actual years you live under it—Interlock is cheaper. Asphalt lasts 15-20 years in Hillside's climate (82 freeze-thaw days, 993 mm rain, 73 cm snow take a toll). You'll replace it twice in 40 years at $8,000–$12,000 per replacement, plus gutters, flashing repairs, and leak fixes in between. Interlock's lifetime limited, non-prorated warranty and aluminum durability mean one installation lasts 40+ years with no replacements. Factor in avoided tear-off waste, lower insurance premiums (some carriers discount Class 4-rated roofs), zero rust repairs, and minimal maintenance, and the total cost-to-keep-your-home-dry favors metal decisively. You stop paying for roofs after the first one.
