Interlock® Aluminum Roofing — all-climates performance specs for Gold Coast, 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.) |

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 Gold Coast
The following metal roofing FAQs are designed specifically for homeowners in Gold Coast, 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 Gold Coast.
Will a metal roof handle Gold Coast's freeze-thaw cycles?
Yes — aluminum expands and contracts with temperature swings, but its oxide layer and four-way interlocking panels accommodate that movement without cracking or delaminating. Gold Coast experiences about 69 freeze-thaw days per year, a serious challenge for brittle materials like asphalt and slate. Aluminum's flexibility is why Interlock roofs have been installed from coastal environments to Antarctic research stations. The 3105-H24 alloy and Alunar coating (30-year PVDF warranty, ASTM D4214 tested) simply age without degrading through repeated cycles.
Can a metal roof rust in a humid climate with heavy rain?
Aluminum cannot rust because it contains no iron — the material that oxidizes and produces rust. Instead, a thin oxide layer forms on the surface and self-heals when scratched, creating a natural protective barrier. In Gold Coast's 1024 mm annual rainfall, this passive defense is especially valuable. Interlock applies Alunar 70% PVDF fluorocarbon coating to both sides of every panel (extra salt-air protection), and the Guardian Warranty covers rusting for the life of your home — a guarantee impossible to offer on steel.
How does a metal roof perform under Gold Coast's annual snowfall?
Metal roofs shed snow and ice efficiently because the smooth, interlocking surface and metal's thermal conductivity prevent ice dams from forming. Gold Coast averages about 73 cm of snow per year, and the four-way panel interlock creates a unified surface with no seams for ice to exploit. Snow guards can be added if desired for gradual release. The system's light weight — Interlock Slate installs at just 0.41 lb/sq ft — means no structural reinforcement is needed, unlike the hundreds of pounds per square foot that snow can load onto asphalt or slate.
Do I need to reinforce my roof structure for a metal roof?
No structural reinforcement is needed. Interlock metal roofing weighs roughly 96% less than concrete or clay tile — the Mediterranean Tile profile installs at only 0.59 lb/sq ft. This light weight is why Interlock can install directly over most existing roofs without adding load. Your home's frame was built to carry asphalt shingles; metal weighs even less, so framing inspection is typically straightforward. This advantage becomes critical in Gold Coast's climate, where the combination of 73 cm annual snow and wind gusts to 95 km/h places stress on older structures — weight savings here means safety and durability.
Will heavy rain cause leaks in a metal roof?
No — the four-way interlocking aluminum panels overlap tightly and shed water faster than any traditional roof. Gold Coast receives about 1024 mm of rain annually, and the metal surface has zero porosity; water cannot absorb into the material. Proper installation with solid decking and underlayment (per ICC-ES ESR-1790 specs) ensures leak-free performance. The Guardian Warranty explicitly covers water intrusion. Unlike asphalt, which degrades and allows water penetration over time, aluminum simply channels rain away — the oxide layer never breaks down from moisture exposure.
Does a metal roof stand up to hail, and can it lower insurance costs?
Yes. Interlock metal roofing carries a 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 durability, combined with non-combustible aluminum (Class A fire available), often qualifies homeowners for insurance discounts. Gold Coast experiences variable storm severity, and metal's proven resilience to impact has made it preferred by insurers. Contact your agent with the UL 2218 rating and ICC-ES ESR-1790 evaluation — these credentials support discount eligibility and may offset installation costs over the roof's lifetime.
Can a metal roof withstand Gold Coast's wind gusts?
Yes. The four-way interlocking panel system is warranted to resist wind speeds up to 120 mph when installed to specification — well above Gold Coast's typical gusts of about 95 km/h (59 mph). The interlocking edges create a unified surface that resists uplift and lateral forces. Wind performance is documented in ICC-ES ESR-1790 (reissued 2025 for current IBC/IRC codes), so your installation meets or exceeds local building standards. This engineered interlocking design is why Interlock panels have been specified in coastal and mountainous environments where wind is a constant load.
What warranty does Interlock offer, and how long will the roof last?
The Guardian Warranty provides a lifetime limited, non-prorated material coverage for the original owner — covering rusting, rotting, splitting, cracking, curling, and loss of impact resistance. It transfers once to the next owner for 50 years from completion, a significant resale advantage. Interlock has manufactured roofing since 1998, with proven durability across 25+ years in the field. Gold Coast's 69 annual freeze-thaw cycles and 73 cm snow load test roofing systems rigorously; this warranty reflects confidence in aluminum's performance under real-world stress. No asphalt or wood product offers comparable terms.
How much maintenance does a metal roof require compared to asphalt or tile?
Metal roofing requires far less maintenance than asphalt or tile. The smooth aluminum surface sheds debris, resists algae and moss growth (verified under CALGreen maintenance standards), and never requires sealing or re-coating. Asphalt degrades annually in UV exposure and needs patching; tile cracks and requires periodic replacement; wood rots and splits. Gold Coast's 3094 annual sunshine hours and frequent rain create ideal conditions for asphalt deterioration, but aluminum's Alunar PVDF coating (30-year fade and chalk warranty, ASTM D4214/D2244 tested) ages without needing renewal. Occasional gutter cleaning is all most homeowners do.
Will a metal roof help reduce cooling costs in summer?
energy-efficient Interlock colors reflect heat rather than absorbing it, lowering cooling costs year-round. Solar reflectance reaches up to 0.55 (Aged Copper Penny), and thermal emissivity is 0.84 — rated by the Cool Roof Rating Council. In Gold Coast's approximately 3094 annual sunshine hours, this reflectivity compounds into measurable savings on air conditioning. Asphalt absorbs heat and transfers it into the attic; metal bounces it back. Combined with aluminum's light weight (no thermal mass to retain heat), the energy advantage shows on utility bills and supports energy-efficiency certification. This is one reason metal roofing is increasingly specified in energy-efficiency retrofits.
Is a metal roof a good choice for Gold Coast’s climate?
Yes. Gold Coast 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.
