Interlock® Aluminum Roofing — all-climates performance specs for Armour Square, 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 Armour Square
The following metal roofing FAQs are designed specifically for homeowners in Armour Square, 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 Armour Square.
How does a metal roof handle Armour Square's annual snowfall?
Interlock panels shed snow efficiently because aluminum's smooth surface resists ice adhesion, and the four-way interlocking system keeps panels secure under the weight of about 73 cm of snow per year. The lightweight design—the Slate profile weighs just 0.41 lb/sq ft—means snow load stresses your home far less than asphalt or clay tile would. Install snow guards if desired to manage sliding; the standing seam profile anchors them securely. Your roof stays watertight through repeated thaw-refreeze cycles, which occur about 69 days per year in this area.
Will freeze-thaw cycles damage an aluminum metal roof?
No. Aluminum expands and contracts slightly with temperature swings, but it does not crack, split, or curl—the exact failure modes Interlock's lifetime warranty excludes. With roughly 69 freeze-thaw days annually in Cook County, this durability matters. The 3105-H24 aluminum alloy is engineered to flex without fatigue over decades. The Alunar 70% PVDF coating (warranted 30 years against chalking) prevents weather degradation that weakens asphalt shingles in freeze-thaw zones. Your roof remains intact and leak-free through thousands of seasonal cycles.
Why does Interlock use aluminum instead of steel for metal roofing?
Aluminum cannot rust because it contains no iron. When exposed, aluminum naturally forms an oxide layer that is itself corrosion-resistant and self-heals if scratched—meaning your roof repairs itself at the molecular level. Interlock applies Alunar 70% PVDF fluorocarbon coating to both sides of every panel, adding another 30-year rated barrier. Armour Square receives about 1024 mm of rain annually, yet aluminum roofs installed here remain structurally sound for 50+ years. Steel roofing rusts and weakens over time; aluminum does not. This distinction defines the lifetime warranty difference.
Can my home's frame support a metal roof, or do I need reinforcement?
Most homes need no reinforcement. Interlock's Mediterranean Tile profile—which replicates heavy clay or concrete tile—weighs just 0.59 lb/sq ft, making it approximately 96% lighter than the tile it mimics. Even the heaviest profile installs over existing asphalt without structural upgrades. This matters in Armour Square: you avoid the cost and disruption of beam reinforcement while gaining authentic tile aesthetics. Interlock panels install directly over your current roof, reducing labor and waste. The four-way interlock system distributes the minimal load evenly, protecting your home's framing from the unnecessary stress of traditional slate, shake, or tile.
How long does installation take, and can you install over my existing roof?
Yes, Interlock installs over most existing asphalt roofs—no tear-off required. Installation timelines depend on roof size and profile; local installer Interlock Metal Roofing, serving this region since 2001, completes most residential projects in 1–3 days. Installing over your current roof saves labor costs and eliminates the landfill waste of asphalt disposal. Underlayment is applied, then panels interlock four ways for wind resistance and watertight sealing. You avoid the disruption of a full tear-off in Armour Square's rainy climate (about 1024 mm annually), keeping weather out during the process. The crew leaves your property clean.
Does a metal roof stay secure in Armour Square's wind gusts?
Yes. Interlock panels are warranted to resist wind up to 120 mph (193 km/h) when installed to specification. Cook County experiences typical gusts around 95 km/h; your roof exceeds that by a factor of 2. The four-way interlocking system locks panels on all four sides, distributing wind loads evenly and preventing uplift. This design earns ICC-ES evaluation ESR-1790 compliance with current IBC/IRC codes. Unlike asphalt shingles, which tear and peel in high gusts, Interlock's aluminum structure remains rigid and sealed. Your roof will not blow off or leak in the windiest days this area sees.
What happens if hail hits my metal roof?
Interlock panels carry a UL 2218 Class 4 impact rating—the highest available—and the warranty covers perforation from hailstones up to 1.5 inches. Class 4 rating means your roof resists damage from the harshest hail events. Check with your homeowner's insurance agent; some carriers offer premium discounts for Class 4-rated roofs because they file fewer claims. Aluminum's ductility (unlike brittle asphalt or tile) means it absorbs impact without cracking. If a stone does puncture a panel, the damage is localized and repairable, not widespread. Interlock's lifetime limited warranty covers impact loss of resistance, so your roof's protective integrity is guaranteed even after the hailstone event.
Will a metal roof reduce my cooling costs in summer?
energy-efficient colors reflect solar heat rather than absorbing it the way asphalt does. Select colors achieve thermal emissivity of 0.84 and initial solar reflectance up to 0.55—measured to Cool Roof Rating Council standards—meaning less heat enters your home. With about 3094 sunshine hours per year in Armour Square, this reflectance adds up over the season. Metal roofs are warmer in winter only if uninsulated; with standard attic insulation, they perform like any roof but without asphalt's heat absorption. The Alunar 70% PVDF coating maintains reflectance for 30 years (ASTM D2244 certified), so your cooling savings persist. Compare the summer electric bill to asphalt and you'll see the advantage.
How much maintenance does a metal roof require compared to asphalt or tile?
Interlock requires minimal maintenance—typically clearing leaves and debris annually. Unlike asphalt shingles, which curl, crack, and lose granules over time in freeze-thaw climates, aluminum does not split or degrade. Unlike wood shake, it resists rot and insect damage. Unlike clay tile, it does not crack from impact or settling. Interlock is CALGreen-verified for reduced maintenance, meaning lower lifetime ownership cost. In Armour Square's 69 annual freeze-thaw days and 1024 mm rainfall, asphalt deteriorates visibly within 15–20 years; aluminum does not. You may inspect gutters and flashing, but the panels themselves remain unchanged for decades. This translates to no sealant reapplication, no spot repairs, and no premature replacement.
Is a metal roof more environmentally responsible than asphalt shingles?
Yes. Interlock aluminum is approximately 95% recyclable at end of life, versus asphalt shingles which become landfill waste. Traditional roofing generates tear-off debris that takes decades to decompose; metal roofing ends that cycle. Aluminum's lightweight design (0.41–0.59 lb/sq ft depending on profile) means lower transportation emissions than slate, tile, or concrete alternatives. Manufactured in Delta, BC since 1998, Interlock panels are engineered for 50+ year lifespan, so you avoid the environmental cost of multiple re-roofing projects over your home's life. After decades of use protecting Armour Square homes through 73 cm of snow and 1024 mm of rain annually, your Interlock roof can be fully recycled, not discarded.
Is a metal roof a good choice for Armour Square’s climate?
Yes. Armour Square 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.
