Interlock® Aluminum Roofing — all-climates performance specs for Near South Side, 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:
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!
My wife recently purchased our home, and we were aware that the roof was getting close to end of life. We researched a few different options and came across Interlock Metal Roof. After meeting with John from InterLock, it became clear to us that a metal roof was the best option for our needs. We plan to live in our home for 30+ years, and while a metal roof is more expensive than a traditional roof, it will be more than worth it over that period of time. We will never have to replace our roof again! It was also great to know that the roof could be installed over the existing shingles, reducing both the mess of the project and the waste created by the old shingles. Jesse and his crew did a great job installing the new roof, and we could not be happier with both the look and the quality of the aluminum shingles. We would recommend InterLock to anyone considering replacing their roof.
Fantastic people to work with, and they did a fantastic job! I was really amazed by them and I loved it!
The investment we made in a new aluminum slate style shingle roof was much more than we wanted to spend, but when we analyzed the pros and cons, including the cost, it came out ahead. We wanted to upgrade our 100-year-old Chicago bungalow and, in particular, rejuvenate the attic and basement spaces. We also want to install a solar panel array on the roof while the current incentives with the IRS, the state and the utility net metering system are still in effect. We wanted to reduce the massive composite shingle tonnage that is covering the incredible sea of roofs across the land. This is undoubtedly a rather large carbon footprint and the short lifespan of many roofs (10-15 years) are causing us to fill and foul unsustainable dumpsites. The weight of our aluminum roof is less than 850 lbs., compared to 3-4 tons of architectural composite shingles. The Interlock roof is a lifetime roof warrantied for 50 years. When/if it is ever replaced, it will be completely recycle-able. Much of the heat captured by composite shingle roofs is reflected by the aluminum. Previously, our attic could reach temperatures near 130°F. We have seen a significant reduction in afternoon attic temps, 10-20 degrees. The installers, Jesse, Sal and Ben were very professional, safe and kind to us. They took the extra time to do it right and solve problems rather than take an easier route. They maintained social distancing and wore masks when necessary. They screwed down OSB sheathing on the existing 100-year-old deck boards which are stamped Sterling Lumber and Supply Co. "The Yards with the Stock". This company was located two blocks from our house in the early 1900s. Interlock continues a tradition from Sterling Lumber to build to last a lifetime. The original 1919 roof rafters were 2"x4"x16' and held up under numerous Chicago blizzards and storms. Prior to the project, we augmented the rafters with 2"x6"x16' #1 southern yellow pine. Hopefully, the roof will bear another century of Chicago climate change. The Interlock Industries' workers installed 95 snow guards to breakup snow slides off the roof. The roof is very attractive and my neighbors have complemented the looks of it. The siding on the dormers were also replaced with the aluminum shingles. We had a choice of several shingle " data-wpil-keyword-link="linked">colors and chose one called gunflint. The shingles have a " data-wpil-keyword-link="linked">slate-like surface that is embossed on the aluminum to give it a textured appearance and perhaps breakup wind and water flows. The Interlock installers removed and sheathed over the chimney and vent caps and added a ridge vent. They installed soffit vents which apparently were never a feature of the house. They removed the gutters and reinstalled them in order to fit the drip edge flashing and lock down the shingles. Everything is fastened with screws powered by cordless screw guns. They did not use air compressors. They had safety lanyards attached to the ridge and foot boards around the perimeter of the roof throughout the installation. We are very satisfied with the look of our new roof and ready to install solar panels which won't have to be removed to re-roof because the roof will probably last longer than the solar panels. We are not young anymore and the long-term value of this project will most likely benefit others and the neighborhood more than us, but for the time being, we are happy customers.
I wanted to write and thank you for all your efforts in working with us to put an Interlock roof on our home. It was a big decision, and all during the process, I felt like you really had our interests at heart. You never tired of answering my questions and your follow-up, whenever I needed to speak with you, was first-rate. I think we had three Interlock crews involved in our project. First came the tear-off guys, who, in our case, had to remove a cedar shake roof before any other improvements could take place. Second, came the install crew, led by “Nacho”, who is absolutely terrific to work with. Ours was a relatively complicated job, with lots of angles, overhangs, gables and pitch to deal with. Nacho made it happen. Finally, the cleanup crew. When Interlock left the job site, my expectations were exceeded. No landscaping was damaged, and the debris was all cleared away. Now, we have a stunning red hidden tile aluminum Interlock roof to look at and enjoy. Perhaps most enjoyable is knowing there will never need to be another roof put on this house. Already, after just a few weeks, we have received numerous compliments from neighbors and friends and see a lot of people slowing in their cars to get a better look. Bob, thanks to you and all the Interlock staff again for your assistance in making this experience a positive one.
I very pleased with the product and pleased with the install. They did a good job. They did a better job than what I was expecting. The put the original flashing on, and I requested they put the flashing on that came with the roof, and they did. It looks much better. It was nice of them to change it for me. I was very pleased. It is what I wanted and I was lucky I found them.
We will definitely be recommending Interlock Roofing to anyone that is looking at replacing their roof. None that i can think of
Telling the real lead time as to when the job could get started. The job got pushed back from December 2016 to May 2017. It was fine with us as we really did not want anyone working on our roof in the winter. The workers and project manager were very professional.
Great company, great product, but too expensive for us to consider at this time.
I think Interlock Roofing could have improved on the timing and having more flexibility in terms of when the project starts.
They could have improved on communication of the status of the project.
I am extremely satisfied with the product. They did a fine job. I can not come up with anything they need to change. I am very satisfied, and the neighbors say they have roof envy.

Metal Roofing FAQs for Homeowners in Near South Side
The following metal roofing FAQs are designed specifically for homeowners in Near South Side, 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 Near South Side.
Will a metal roof hold up to Chicago's freeze-thaw cycles?
Yes—aluminum actually thrives in freeze-thaw conditions because it has no water absorption. Near South Side experiences about 69 freeze-thaw days per year, which breaks down asphalt and causes wood to split and crack. Aluminum's oxide layer doesn't degrade when water freezes in surface scratches; the layer self-heals. The 3105-H24 / 3003-H24 alloy won't expand and contract unevenly the way composite materials do, so you won't see the curling and buckling common in older neighborhoods after a harsh winter.
Does Interlock handle heavy snow loads on a Cook County roof?
Interlock's four-way interlocking panels shed snow reliably even under Near South Side's typical 73 cm annual snowfall. The panels lock so tightly that snow doesn't migrate into seams or pool at transitions. Because aluminum weighs just 0.41 lb/sq ft for the Shingle profile—about 96% lighter than concrete or clay tile—your roof structure carries the snow load with ease, and no reinforcement is needed. Snow guards are available if you want to control shedding on lower-pitched roofs; the lightweight system handles them without stress.
How does a metal roof prevent leaks in a rainy climate?
The four-way interlocking design prevents water from entering gaps between panels, even during Near South Side's average 1024 mm of annual rainfall. Each panel locks top, bottom, left, and right to its neighbors, creating a continuous sealed surface. Water that contacts the panel sheds downward by gravity; underneath, a solid deck and underlayment (installed per ICC-ES ESR-1790 specs) channel any moisture toward gutters. Unlike asphalt, which absorbs water and degrades, aluminum is impervious—the surface never softens or swells, so the seal integrity doesn't weaken over decades.
Why does aluminum resist rust better than steel roofing in Illinois?
Aluminum cannot rust because it contains no iron; the rusting process requires iron to oxidize. Instead, aluminum develops a thin, invisible oxide layer that self-repairs when scratched—a property unique to the metal. Steel, by contrast, oxidizes continuously and requires paint or coatings to slow the process. Interlock uses roofing-grade 3105-H24 / 3003-H24 aluminum with a Alunar® 70% PVDF fluorocarbon finish on both sides, warranted 30 years against chalking and fading. In Cook County's humid environment with freeze-thaw stress, this distinction means your roof's structural integrity stays intact while steel gutters and fasteners around it may corrode.
Can Interlock stand up to Cook County wind gusts?
Yes. The four-way interlocking panels are warranted to resist sustained winds up to 120 mph, which far exceeds Near South Side's typical daily-max winds of about 25 km/h and rare gusts to 95 km/h. Each panel locks firmly to its neighbors, distributing wind load across the entire roof plane rather than letting individual shingles lift or flutter. This continuous, rigid connection is why Interlock panels perform so well in high-wind testing. Unlike asphalt shingles, which can lift and tear, or standing-seam panels that depend on fasteners alone, the interlocking system gives you inherent structural stability in seasonal storms.
Do I need to reinforce my house framing for a metal roof?
No structural reinforcement is needed. Interlock's lightweight construction—the Mediterranean Tile profile installs at just 0.59 lb/sq ft, about 96% lighter than traditional clay or concrete tile—means most existing roof structures can carry the system without modification. A typical asphalt roof weighs 3–5 lb/sq ft; Interlock Shingle weighs 0.41 lb/sq ft. This matters in Chicago's climate because a lighter load reduces stress from snow (Near South Side averages 73 cm annually) and means no expensive framing upgrades. You can install Interlock directly over most existing roofs, saving the cost of a full tear-off and disposal.
Will hail damage hurt my metal roof, and can I get an insurance discount?
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. Class 4 means the roof resists severe impacts that would dent or puncture asphalt or wood. Some insurance companies offer premium discounts for Class 4-rated roofs because the risk of interior water damage and claim frequency drops dramatically. While Near South Side's hail exposure is moderate compared to plains states, the Class 4 rating protects you against unexpected severe storms and strengthens your home's overall resilience. Contact your insurer about discount eligibility once the roof is installed.
Does a metal roof really save money on cooling costs in Illinois?
energy-efficient colors with thermal emissivity 0.84 and initial solar reflectance up to 0.55 reduce cooling load in summer while Near South Side receives about 3094 sunshine hours per year. These reflective coatings bounce heat away before it enters the attic, lowering air-conditioning demand on hot days. Asphalt shingles, by contrast, absorb heat and transfer it indoors. The Cool Roof Rating Council rating confirms measurable energy savings. In a city where summer cooling is routine and your roof faces 3000+ hours of sun annually, this reflectance translates to lower energy bills over the roof's lifetime—a hidden but real value that compounds year after year.
What's the real lifetime cost difference between Interlock and asphalt shingles?
Asphalt typically costs less upfront but requires replacement every 15–25 years; Interlock costs more initially but lasts decades longer with zero need for tear-off cycles. A typical Cook County home might install asphalt three times in 50 years—three disposal bills, three installation fees, three supply-chain disruptions. Interlock's lifetime limited warranty (non-prorated for the original owner, transferable 50 years from completion) eliminates that cycle. When you factor in avoided labor, disposal, and landfill costs over a 50-year ownership window, the per-year cost of Interlock becomes competitive—and if you sell, the transferable warranty adds resale value that asphalt cannot match.
What does Interlock's warranty actually cover, and how long does it last?
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. Because aluminum cannot rust and contains no organic material, these common failure modes don't apply—the warranty protects against defects in manufacture, not normal wear. The warranty transfers once to the next owner for 50 years from completion, giving buyers peace of mind and you a selling point. This depth of coverage reflects the engineered durability of 3105-H24 / 3003-H24 aluminum with a 30-year PVDF coating warranty. No asphalt or composite shingle offers comparable protection.
Is a metal roof a good choice for Near South Side’s climate?
Yes. Near South Side 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.
