Interlock® Aluminum Roofing — all-climates performance specs for Lower West 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 Lower West Side
The following metal roofing FAQs are designed specifically for homeowners in Lower West 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 Lower West Side.
Will a metal roof handle Lower West Side's freeze-thaw cycles without cracking or degrading?
Yes—aluminum's crystalline structure actually strengthens under freeze-thaw stress, unlike asphalt or wood shingles that crack after repeated expansion and contraction. With about 69 freeze-thaw days per year in Cook County, your roofing material takes a beating. Interlock's 3105-H24 aluminum alloy (ASTM B209) was designed for exactly this: it flexes without fracturing. The four-way interlocking panels allow micro-movement, and the Alunar 70% PVDF fluorocarbon coating (warranted 30 years) won't chalk or peel even as temperatures swing. You get durability where cheaper materials fail.
Why can't an aluminum metal roof rust, and does that matter in Illinois?
Aluminum cannot rust because it contains no iron—the element that oxidizes and corrodes. Instead, aluminum forms a transparent oxide layer that heals itself when scratched, so surface damage doesn't spread. In a climate with 1024 mm of annual rainfall and freeze-thaw cycles, that self-healing property is a huge advantage: water can't penetrate or initiate the deep corrosion that would destroy steel. Interlock's roofing-grade aluminum (3105-H24 and 3003-H24) was developed for harsh environments from coastal salt air to Antarctic stations. You pay once and skip the rust inspection anxiety for life.
How does a metal roof perform with about 73 cm of snow per year and ice dam risk?
Metal roofing sheds snow and ice far more reliably than asphalt because its smooth, hard surface doesn't trap moisture the way porous shingles do. Snow slides off more readily, reducing ice dam formation—a major problem in Lower West Side's cold, wet winters. The four-way interlocking panels lock together so tightly that no water backs up between seams. If you add optional snow guards, you control shedding. The real win: Interlock's lightweight panels (Slate at 0.41 lb/sq ft) mean your structure carries a fraction of the load of traditional slate or tile, so winter snow accumulation won't stress your framing the way it would with heavier materials.
Can a metal roof withstand Cook County's wind gusts without failure or leaks?
The warranty covers wind speeds up to 120 mph, and Lower West Side's typical gusts reach about 95 km/h (59 mph), so you're well within safety margins. Four-way interlocking panels are the key: each panel locks to its neighbors on all four sides, creating a unified system that resists uplift and lateral shear. During high wind, the panels flex as a unit rather than flapping or separating. That engineered interlock is why Interlock Metal Roofing can stand behind a 120 mph warranty when competitors can't. In a region where spring and winter wind is routine, that reliable hold-down matters more than it sounds.
Does a metal roof reduce hail damage risk, and could insurance rates drop?
Interlock achieves UL 2218 Class 4, the highest impact rating available, and the Guardian Warranty even covers perforation from hailstones up to 1.5 inches. Class 4 means the roof survived impact equivalent to a 2-inch steel ball dropped from 52 inches—far tougher than asphalt or wood. Many insurance companies recognize this and offer premium discounts for Class 4 roofs because claims risk plummets. In Cook County, where severe weather includes hail, that combination of genuine durability and potential insurance savings adds real dollars back to your pocket. Ask your agent whether your policy qualifies for a reduction; many insurers have started offering them for metal.
Will an Interlock metal roof with reflective coating reduce cooling costs in Illinois?
energy-efficient Interlock colors reflect significant solar heat instead of absorbing it like asphalt does. The Cool Roof Rating Council measurement shows initial solar reflectance up to 0.55 (Aged Copper Penny) and thermal emissivity of 0.84, meaning the roof stays cooler and radiates heat away efficiently. Over Lower West Side's 3094 sunshine hours per year, that reflectance compounds: less heat absorbed means lower AC run time in summer. The effect is modest in Illinois compared to Arizona, but measurable—especially on south and west exposures. Pair a reflective color with your insulation, and you're shaving cooling demand without any moving parts to fail.
Can I install a metal roof over my existing shingles without structural reinforcement?
Yes—Interlock's Mediterranean Tile profile weighs only about 0.59 lb/sq ft, roughly 96% lighter than concrete or clay tile, so no structural upgrades are needed. Most existing residential framing easily supports metal roofing installed directly over asphalt. Eliminating tear-off saves labor and disposal cost, plus you gain an extra insulation layer. The installation process is faster too: crews don't strip the old roof, which reduces timeline and disruption. With about 73 cm of snow bearing down annually, that light weight is a practical advantage—your structure carries a fraction of the dead load compared to materials that would require reinforcement. Many homes qualify for over-install, but a local inspector can confirm your specific framing.
What's the actual lifespan and warranty coverage on an Interlock metal roof?
The Guardian Warranty is lifetime limited and non-prorated for the original owner—it covers rusting, rotting, splitting, cracking, curling, and loss of impact resistance, with no dollar caps or annual limits. When you sell, it transfers once to the next owner for a full 50 years from completion, a major resale asset. Aluminum doesn't rot or rust, and the Alunar 70% PVDF coating is warranted 30 years against chalking and fading (measured to ASTM D4214 and D2244). Real-world installations since 1998 show roofs still functioning flawlessly after 20+ years. In a freeze-thaw climate like Cook County with 69 cycles per year, that permanence beats asphalt, which typically needs replacement every 15–20 years.
What metal roofing profiles does Interlock offer for Lower West Side homes?
Interlock makes five profiles: Slate (0.41 lb/sq ft, mimics classic slate texture), Cedar Shingle, Shake, Mediterranean Tile, and Standing Seam. Each uses the same four-way interlocking aluminum construction and Alunar 70% PVDF coating, so performance is identical—the difference is aesthetic. Slate and Cedar Shingle suit traditional homes; Shake and Tile fit period or Mediterranean designs; Standing Seam works modern or farmhouse. All install at a fraction of the weight of actual materials, so you get authentic visual appeal without the structural demands. The choice depends on your home's architecture and your preference, but your durability, warranty, and weather resistance stay the same regardless of profile.
How much maintenance does a metal roof really need compared to asphalt or tile?
Almost none: aluminum doesn't rot, split, or curl, so you skip the costly inspections and repairs asphalt and wood require. Gutters need cleaning after leaf season, and you should inspect flashing once every few years—that's it. The Alunar coating resists dirt accumulation and doesn't degrade, so no pressure washing needed. CALGreen has verified Interlock for reduced maintenance. In Lower West Side's wet, freeze-thaw climate, where asphalt shingles crack, moss grows, and tar splits, a metal roof simply outlasts the wear cycle. Over 69 freeze-thaw days per year and 1024 mm of rain, that low-maintenance promise saves you thousands in repairs and contractor calls. You're buying a roof that works quietly in the background for decades.
Is a metal roof a good choice for Lower West Side’s climate?
Yes. Lower West 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.
