Interlock® Aluminum Roofing — all-climates performance specs for South Loop, 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 South Loop
The following metal roofing FAQs are designed specifically for homeowners in South Loop, 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 South Loop.
Does metal roofing handle South Loop's 73 cm of annual snow and ice buildup?
Aluminum's extreme light weight—the Shingle profile at 0.41 lb/sq ft—eliminates snow load stress on your home's frame and allows installation over most existing roofs without structural reinforcement. The four-way interlocking panels resist wind gusts up to 95 km/h common in Chicago winters, and the warranty covers wind speeds to 120 mph. South Loop receives about 70 freeze-thaw cycles annually; aluminum oxide coating self-heals through freeze-thaw cycling, unlike asphalt, which cracks and curls under the same stress. Snow guards can be added if you prefer controlled shedding.
How does aluminum metal roofing perform in freeze-thaw climates?
Aluminum's oxide layer naturally self-heals when exposed to oxygen, a process that continues through South Loop's roughly 69 annual freeze-thaw days without degradation. Unlike asphalt or wood shakes, which crack and split under repeated expansion and contraction, roofing-grade 3105-H24 aluminum alloy maintains structural integrity across temperature swings. The Alunar 70% PVDF coating is warranted 30 years against chalking and fading, tested to ASTM D4214 standards—far outlasting single-coat systems in cold-wet climates. This material combination is why Interlock panels have performed from coastal salt-air to Antarctica since 1998.
What hail impact rating does Interlock metal roofing carry, and could it lower insurance costs?
Interlock achieves UL 2218 Class 4, the highest available impact rating, and the Guardian warranty explicitly covers perforation from hailstones up to 1.5 inches. South Loop experiences variable severe weather; this rating means you're protected against the most extreme hail events. Many insurers offer premium reductions or discounts for Class 4-rated roofs because claims are statistically rare. Contact your agent with the UL 2218 Class 4 designation and ICC-ES ESR-1790 evaluation report (reissued 2025) to discuss potential savings. The combination of impact resistance and non-combustibility often qualifies for favorable underwriting.
How does a metal roof handle South Loop's heavy rainfall without leaks?
The four-way interlocking panel system creates a mechanical seal that sheds water like shingles on a slope; with about 1024 mm of annual rain, this design is proven and field-tested across wet climates worldwide. When installed over solid roof decking with underlayment—a standard specification in ESR-1790—water is directed away before reaching framing. The interlocking overlap is tight enough that wind-driven rain at 95 km/h gusts cannot force water upward. Aluminum's oxide layer does not absorb moisture, so even standing water on the roof surface does not degrade the material. Proper deck preparation and underlayment installation are your insurance against leaks.
Will an aluminum metal roof stay secure in Chicago's winter and spring wind gusts?
The four-way interlocking design warranties wind resistance to 120 mph when installed to specification; South Loop's peak gusts around 95 km/h are well within this safety margin. Interlock panels lock mechanically on all four edges, so wind cannot lift or separate them as it can asphalt shingles or poorly fastened tiles. This engineering is documented in ICC-ES ESR-1790, which verifies compliance with IBC and IRC wind load tables. The lightweight profile—Shake at 0.58 lb/sq ft—means wind pressure has minimal leverage. Installation by Interlock's local crew since 2001 ensures fastening follows specifications that hold through Chicago's seasonal storm season.
Can my South Loop home support a metal tile roof without structural upgrades?
The Interlock Mediterranean Tile profile weighs approximately 0.59 lb/sq ft, making it roughly 96% lighter than concrete or clay tile. South Loop homes built to standard residential codes can support this weight without reinforcement; most existing roofs can have Interlock installed directly over them, eliminating tear-off costs and labor. This light weight is made possible by roofing-grade aluminum alloy, not steel or composite materials. Structural engineers and building officials recognize that aluminum tile poses no additional load burden compared to asphalt shingles. The result: you get the authentic tile aesthetic without foundation or framing upgrades.
Does Interlock metal roofing need regular maintenance like asphalt or wood?
Aluminum roofing requires no granule replacement, no resealing, no wood treatment, and no moss removal—maintenance tasks that consume asphalt and shake roofs over their lifetimes. South Loop's roughly 3094 annual sunshine hours and wet winters create conditions ideal for mold and algae growth on asphalt; Interlock's oxide-coated aluminum surface discourages biological colonization. The CALGreen-verified design reduces maintenance workload and cost. Occasional visual inspection and debris clearing is advisable, but structural maintenance is minimal. This contrasts sharply with slate or tile roofs that crack and require individual replacement, or asphalt that needs recoating every 10–15 years in South Loop's climate.
Is a metal roof worth the upfront cost compared to asphalt shingles in South Loop?
Over a 50-year horizon, Interlock eliminates the cycle of asphalt tear-offs (every 15–20 years in wet climates) and associated labor, disposal, and reinstallation costs. The Guardian warranty is lifetime limited and non-prorated for the original owner; the transferable 50-year term for the next owner preserves resale value. South Loop's 69 annual freeze-thaw cycles and 1024 mm of rain accelerate asphalt degradation; aluminum's oxide self-healing means no premature failure in those conditions. One upfront installation cost, no roof replacements for your ownership term, and a home that retains curb appeal and structural integrity throughout—that is the value calculation. A metal roof is the last roof you buy.
Is Interlock metal roofing recycled or recyclable?
Interlock panels are approximately 95% recyclable aluminum and can be recovered and remelted indefinitely without loss of material properties. By contrast, asphalt shingles tear off every 15–20 years and go to landfill; over 50 years, a typical South Loop home generates tons of waste destined for disposal. Aluminum's infinite recycling cycle breaks that pattern. Roofing-grade 3105-H24 and 3003-H24 alloys meet ASTM B209 standards and maintain value in scrap markets. CALGreen verification confirms Interlock's reduced maintenance profile also means fewer chemical treatments, sealants, and interventions over the roof's life. Choosing aluminum is the environmentally responsible path: one installation, no landfill contribution, 100% material recovery when the roof eventually reaches end-of-life.
Who installs Interlock metal roofing in South Loop, and how long has the contractor been in business?
Interlock Metal Roofing has served the South Loop and Cook County region since 2001—over two decades of local installation experience and warranty support. The company manufactures panels in Delta, BC, and maintains inventory and scheduling tailored to Chicago's seasonal demands. Direct factory-to-installer relationships ensure your project receives authentic Interlock materials and installation methods documented in ICC-ES ESR-1790. Local presence means fast response for inspections, warranty claims, or future maintenance questions. When you choose a South Loop roofer, continuity of service and accountability matter; Interlock's 24-year track record in this market demonstrates both.
Is a metal roof a good choice for South Loop’s climate?
Yes. South Loop 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.
