Interlock® Aluminum Roofing — all-climates performance specs for Streeterville, 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 Streeterville
The following metal roofing FAQs are designed specifically for homeowners in Streeterville, 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 Streeterville.
Will a metal roof handle Streeterville's freeze-thaw cycles without cracking or splitting?
Yes—aluminum expands and contracts smoothly without cracking because it's a homogeneous metal, not a brittle composite like asphalt or tile. Cook County experiences about 69 freeze-thaw days per year, a real challenge for shingles that trap moisture and degrade over time. Interlock's 3105-H24 aluminum alloy flexes with temperature swings; the four-way interlocking design lets panels move independently without stressing seams. The Alunar coating, warranted 30 years against chalking and fading, stays intact through those cycles, protecting the aluminum underneath.
How does a metal roof handle heavy snow load, and do I need snow guards in Streeterville?
Metal roofs shed snow efficiently because of their smooth, slippery surface—unlike asphalt, which traps moisture and ice. Streeterville averages about 73 cm of snow yearly, but the Interlock panels' light weight means your home's frame carries less total load than if you installed traditional tile or slate. Snow can accumulate in certain profiles like the Cedar Shingle or Shake; snow guards are a smart addition if you have a steep pitch or a walkway below. The four-way interlocking design prevents panel separation under snow pressure, so structural integrity stays intact even in heavy winters.
Can a metal roof withstand Streeterville's wind and ice-storm gusts without failing?
Interlock roofs are warranted to resist wind speeds up to 120 mph—well beyond the typical 95 km/h gusts recorded in Cook County. The four-way interlocking system locks each panel to its neighbors on all four sides, distributing wind load across the entire roof rather than placing stress on fasteners. This design means your roof stays intact during spring and winter storms common to the region. The ICC-ES evaluation report ESR-1790 confirms the assembly meets IBC and IRC wind-resistance standards, so you're covered by both warranty and building code.
Why can't an aluminum metal roof rust, and does that matter in Illinois winters?
Aluminum cannot rust because it contains no iron—the element that oxidizes and corrodes. Instead, aluminum forms a thin, self-healing oxide layer when exposed to air. Even if the coating scratches or the edge is cut during installation, the oxide reforms and protects the underlying metal. Illinois winters bring salt-treated roads, moisture, and freeze-thaw cycles that accelerate rust in steel or galvanized roofs. Interlock has been installed from coastal salt-air homes to Antarctic research stations; the roofing-grade 3105-H24 alloy and two-sided Alunar PVDF coating ensure long-term durability without corrosion in harsh conditions.
Will hail damage my metal roof, and can I get an insurance discount?
Interlock metal roofs carry a UL 2218 Class 4 impact rating—the highest available—and the warranty even covers perforation from hailstones up to 1.5 inches. Class 4 performance makes Interlock eligible for insurance discounts in many regions because underwriters recognize the reduced claim risk. Hail is less common in Cook County than in the Great Plains, but spring and summer storms do occur. The aluminum's strength and rigidity mean it resists denting and puncture better than asphalt or wood shakes. Talk to your insurance agent about potential premium savings; many carriers acknowledge the durability difference.
Is a metal roof light enough to install over my existing asphalt shingles without reinforcing the frame?
Yes—Interlock's exceptional lightness is one of its biggest structural advantages. The Slate profile installs at only 0.41 lb per square foot, and even the heaviest option, the Mediterranean Tile, weighs just 0.59 lb per square foot—roughly 96% lighter than real concrete or clay tile. Most existing homes can support this weight without frame reinforcement. Streeterville homes built in the past 50 years have roofs rated for asphalt (about 2–3 lb per square foot), so aluminum is a straight swap. You can install over your existing roof in many cases, which saves money on tear-off and disposal.
How much upkeep does a metal roof need compared to asphalt or wood shakes?
Metal roofs require far less maintenance than asphalt, wood, or tile. Asphalt shingles need nail replacement, moss removal, and gutter clearing every few years; wood shakes split, cup, and rot in Streeterville's 69 annual freeze-thaw days. Interlock aluminum sheds debris naturally because water doesn't pool and the surface doesn't degrade. You'll clear gutters and remove leaves—standard for any roof—but you won't replace shingles, treat rot, or deal with cracking. The Alunar coating is warranted 30 years against chalking and fading, so repainting is never required. CALGreen verification confirms minimal maintenance demands over the roof's life.
Can a metal roof actually lower my cooling costs in summer?
energy-efficient Interlock colors reflect more solar heat than asphalt, reducing heat absorption into your attic and lowering cooling demand on hot days. Thermal emissivity ratings reach 0.84, and initial solar reflectance climbs to 0.55 in cooler colors like Aged Copper Penny. Streeterville averages about 3094 sunshine hours per year; that's substantial exposure to solar gain, especially May through September. A reflective metal roof bounces that energy away rather than trapping it like dark asphalt does. The Cool Roof Rating Council rating backs these performance claims. Savings depend on your AC usage and local electricity rates, but reflective metal consistently outperforms asphalt in energy modeling.
How does the lifetime cost of a metal roof compare to asphalt shingles over 50 years?
Upfront, metal costs more than asphalt, but over a typical home's ownership period, the math favors metal. Asphalt shingles last 15–20 years in Streeterville's climate (freeze-thaw damage, UV, moisture), meaning you'll replace them twice to three times. Each tear-off, haul, and reinstall costs thousands. Metal roofs typically last 50+ years with normal maintenance; the Guardian lifetime limited warranty covers the original owner and transfers once to the next owner for 50 years from completion. No tear-offs, no landfill waste, no repeat labor. Insurance discounts for hail resistance and energy savings on cooling further offset the higher initial cost—making metal the cheaper choice when you measure total lifecycle expense.

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.
