Interlock® Aluminum Roofing — all-climates performance specs for Lake Como, Wisconsin
| 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:
Your home is your greatest investment, sheltering you from the storms. Don’t nickel and dime yourself when choosing a roof, you get what you pay for. We chose Interlock aluminum roofing for our house,and are totally pleased with it. Aluminum doesn’t rust period. The current rage of steel roofing is a racket preying on uninformed consumers who want something for next to nothing. Steel roofs are coated to prevent rust. However, once these coatings wear off rust sets in. I have personally seen an 18 year-old steel roof with significant rusting after the coating was gone. Do yourself a favor, get an Interlock aluminum roof. Dean Landers 5 star review June 9/2026 Janesville WI
I had Interlock put on a beautiful red slate roof 17 years ago.The roof still looks beautiful. 5 years ago, I had them also re-roof my garage with the same type of slate. The roofs look gorgeous and I have no maintenance whatsoever.I get complements all the time. The guy whom I contracted with was named "Tim' but has since died. He was a really nice guy. Back in 2009, the roof was much cheaper. ( I actually paid more for the garage 5 years ago!) I am extremely happy with the roofs. The guys did a wonderful job, replacing rotted boards where necessary. They also told me about very cheap gutters I could buy at Menards instead of those ridiculously - priced "special" gutter systems. I bought them and they placed them on my buildings.This home will go to my daughter one day; I do not want her to have to lift a finger. Note that I had an asphalt roof previously. It lasted only 12 years. The shingles curled up under the sun and cracked. They looked terrible. I can honestly say that these metals roofs by Interlock are very much worth what you pay for them. They will last a lifetime with almost no maintenance. Instead of replacing a roof every 15 years and paying lots for asphalt or fiberglass, their metal roofs last very long and you will never have to re- roof again.
Our experience with having our Interlock roof installed was exceptional. It was installed during the hottest days of the year, and none of our neighbors could believe the installers were working so hard during the hot, muggy weather. They finished several days ahead of schedule and left the yard clean and neat, even after a complete tear-off of three layers of roofing. One day during the installation, we had a rain storm, and the installers all took shelter in their vehicles. I noticed that we had a leak in a spot that had clearly had leaks before we bought the house. When I pointed it out to the installers, they went up the ladder in the pouring rain, found the cause of the problem (which, again, was a pre-existing problem, not one due to the Interlock installation) and fixed it on the spot. The service was exceptional.
We purchased our roof in 2009 and as you can see from the pictures taken in May of 2017, our roof looks as new as the day we bought it. Here are the things we have noticed most about our Interlock Lifetime Roof over the last 8 years. It keeps our house much cooler in the summer than the asphalt roof we used to have. It really sheds snow, and the snow guards work great. We never need to use a snow rake. We love the durability and the curb appeal. Greg Weber our representative, who we were enthused to learn, is still with the company. When we saw him in 2009 he laid out all the variables in a professional way and our Interlock Roof has lived up to all of our expectations and promises he made. All companies promise results, service, and quality. Interlock delivers.
The installation was super smooth. Every installer was courteous and professional. We get lots of compliments, and people stop by all the time to admire it. One of the biggest misconceptions about metal roofing is people think it’s loud. Our Interlock roof is very silent. The only way I know if it’s raining is if I look out a window. Also, the snow just slides off. We are also in a wind tunnel area, and we have never lost an Interlock shingle, and we have had the roof for many years. We were so pleased with our Interlock roof that we put the same roof on our lake home in northern Wisconsin. We get a lot more snow up there and the Interlock’s snow-shedding performance capabilities are second to none on that roof, too!
First off, the installation crew was great! They worked very hard, took short breaks, and completed the job very efficiently. Greg Weber, our sales representative, told us an Interlock Roof was more energy efficient than asphalt, and one of the major things we noticed over the years is how much cooler our home office upstairs is in the summertime and warmer it is in the wintertime. It’s a dramatic difference from our old asphalt roof. We have had a few neighbors even question why we invested more in an Interlock roof than a typical asphalt roof, and we always smile and say, “Everybody complains about spending money. Do you want to complain about it once or multiple times, and do you want to be all in to have the best, or not in, and hope for the best.” Thank you, Interlock!
Dear Interlock Lifetime Roofing Systems, The installation was terrific. Jessie and his crew were very nice, polite, and clean and worked together like a well-oiled machine. If I was to have work done on my home for any type of project, this is the team I would recommend and would want to work on my house. Greg Weber, my sales representative, answered all my questions, set the proper expectations, and over delivered in every aspect. We had a major rainstorm shortly after the installation, and we noticed no difference in sound at all. Our Interlock roof is the talk of the neighborhood.
Dear Interlock Lifetime Roofing Systems: We purchased our Interlock Lifetime Roof in June 2014. We are very happy with the look, durability of the material, and finish. After a snowfall, the heat of the sun will warm the roof and allow the snow to shed from the roof. We have a great sense of security, knowing it can withstand higher winds than conventional asphalt. In fact, our neighbors lost many shingles in the last major wind storm, and our Interlock roof proved to be the high wind resistance product it is with all shingles intact. We love the fact it’s more reliable and has peace of mind knowing it has lots of longevity and will look brand new not only now but down the road. We also received a discount on our homeowner’s insurance. Overall, we were very satisfied with our sales representative Greg Weber, the company, the service, and the product.
We have been do-it-yourselfer homeowners our whole lives. We are very handy and capable when it comes to home improvements and appreciate craftsmanship and quality. And that’s what Interlock Lifetime Roofing Systems provided us with our roof. Craftsmanship and quality. Plus, durability, beauty, and experience from a company that manufactures and certify install its own product. That is something, a company that makes its own product, that was very important to us, and no other company in our market offered that, except Interlock. Another thing that was important was we didn’t want to have to deal with rust because many steel metal roofs look good new but look old and hideous down the road because of fading and rusting. Interlock is aluminum. So, it won’t rust, and it achieves and exceeds the highest rating of hail resistance. So, it’s like we said earlier – super durable! Jessie and his crew were super and hard working. We were amazed by their work ethic. That’s something that’s becoming rare nowadays. Also, we were told by a competitor that Greg Weber and Interlock would be high-pressure. That was the furthest thing from the truth. Greg was polite, personable, and knowledgeable and helped us sift through the “lesser quality, cheaper installation, sales gimmicky and overly aggressive” competitors. He provided us with a detailed range of the competition by laying out all the variables so we could make an intelligent comparison and decision. Greg helped save us a lot of time from all the other companies in our market selling what everyone else is selling or just selling stuff and making promises they can’t keep. All the asphalt guys want you to believe that their products will last, and all the steel companies want you to believe their products won’t rust, and everybody knows… That’s Just Not True! Interlock has proven itself for over four decades. That’s Impressive. That’s why we went with them, Jessie and Greg.
In March 2017 we had an Interlock Lifetime Roof installed. Greg Weber, the salesman, was not pushy. We were very impressed with his salesmanship and the product. He also offered to have the Interlock product put on our wishing well in the front yard. That was something we really appreciated. The clean-up was excellent! Many neighbors and people who " data-wpil-keyword-link="linked">walk by the house have noticed the roof and asked a lot of questions. We have gotten lots of compliments!
We visited the booth Interlock had at the Remodelling Show at State Fair Park. We got a lot of excellent information there and left our number for a call-back. We did receive the call back promptly and got an appointment right away. The estimator showed up on time and thoroughly explained the process, the product choices and the costs. We signed up for a new metal roof that evening because the advantages were so many, and the expense over time was not much different from regular shingles. This metal roof will probably outlive us! The actual work didn’t start for about two months because the company was very busy, but removing the old layers of shingles was the first process. This was done in a day, and the waterproofing membrane went on. The roofing materials were supposed to be delivered in a couple of days, which unfortunately didn’t happen.

This was done in a day, and the waterproofing membrane went on. The roofing materials were supposed to be delivered in a couple of days, which unfortunately didn’t happen. Instead, a heavy, rainy week intervened, and we did get water in our kitchen. It took a while to get someone to call me back and that was frustrating because it damaged our kitchen ceiling. Ultimately, though, I did get a call, and the work was expedited to the following day. The roofers did the entire installation in one day and did a great job. The roof is beautiful, and we have many people stopping and looking at the wonderful work and superior materials. I know the company will honor their promise to pay for the damage to the kitchen. Once that is done, all is well. The experience wasn’t perfect, but it was as close as mother nature and shipping glitches allowed.
The Interlock crew was able to take some extra time to coordinate with another contractor for solar installation. As a result, the final the result looks great and very functional. The materials used are very high quality, and they worked efficiently and cleaned up when finished.

Metal Roofing FAQs for Homeowners in Lake Como
The following metal roofing FAQs are designed specifically for homeowners in Lake Como, Wisconsin. 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 Lake Como.
How does a metal roof handle Lake Como's heavy snow and ice?
Interlock's four-way interlocking panels are warrantied to 120 mph wind resistance, which anchors snow in place during Lake Como's typical gusts up to 100 km/h; the lightweight aluminum (Slate at 0.41 lb/sq ft) bears snow loads without structural upgrade, while the smooth panel surface sheds melt efficiently during the region's approximately 83 freeze-thaw days per year. The panels' mechanical interlock prevents ice-dam-driven water infiltration that compromises asphalt in freeze-thaw cycling.
Why does aluminum outperform other roofing in freeze-thaw climates?
Aluminum expands and contracts uniformly with temperature swings—it has no grain, no wood fibers to split, and no brittleness from repeated ice-thaw cycles. Interlock's 3105-H24 / 3003-H24 alloy is engineered specifically for this stress: after 83 annual freeze-thaw days in Walworth County, asphalt becomes brittle and wood shakes crack, but aluminum's oxide layer self-heals surface scratches and the metal itself never weakens from cold. The Guardian Warranty covers splitting and cracking—a direct statement of this durability.
Can aluminum roofing rust or corrode in a Wisconsin climate?
Aluminum cannot rust because it contains no iron; instead, it develops a transparent oxide layer that self-heals when scratched—a natural defense that strengthens over time. Lake Como receives about 838 mm of rain annually and moisture exposure cannot penetrate the Alunar 70% PVDF fluorocarbon coating, which is warranted 30 years against chalk and fade (ASTM D4214). Steel roofing, by contrast, requires constant vigilance in wet climates; aluminum needs none.
What does Interlock's warranty actually cover, and how long does it last?
The Guardian Warranty is a lifetime limited, non-prorated material warranty for the original owner—covering rusting, rotting, splitting, cracking, curling, and loss of impact resistance with no deductible or time limit. It transfers once to the next owner, who receives 50 years of coverage from completion. This structure means your home keeps its roof through resale without the anxiety of a prorated schedule; competitors' warranties typically turn prorated after 10–20 years, costing owners thousands in year 25.
Will my insurance company discount a Interlock metal roof after hail?
Interlock's UL 2218 Class 4 impact rating—the highest available—often qualifies for insurance discounts because the roof itself resists the kind of damage that triggers claims. The warranty covers perforation from hailstones up to 1.5 inches; in real-world Wisconsin hail events, impact damage to asphalt or wood is routine, but aluminum's inherent hardness and the panel's mechanical interlock distribute impact force. Contact your carrier with the ESR-1790 evaluation report and UL 2218 rating to discuss your specific discount.
Does a metal roof that looks like slate or tile need a structural upgrade?
No—Interlock's Mediterranean Tile profile weighs about 0.59 lb/sq ft, roughly 96% lighter than concrete or clay tile, so your framing supports it without reinforcement. Real slate or ceramic tile can require $8,000–$15,000 in structural work before installation; Interlock installs directly over most existing asphalt roofs, saving time and money. The four-way interlock locks panels to the deck, so light weight becomes an advantage: less strain during Lake Como's 100 km/h wind gusts.
What maintenance does an Interlock metal roof actually need?
After initial installation, virtually none beyond seasonal gutter cleaning—the same task any roof requires. Aluminum does not split like wood shakes, does not curl like asphalt in Wisconsin's 3,084 annual sunshine hours, and does not require the expensive fungicide treatments wood demands in humid climates. The 30-year-warranted Alunar coating resists chalking and fading without re-coating. Compare this to asphalt (tar breakdown every 15–20 years), wood (annual staining, split repair), or tile (cracked pieces every few years in freeze-thaw).
Can Interlock install a metal roof over my existing shingles?
Yes—one of metal roofing's great advantages. Interlock installs over most existing asphalt roofs without tear-off, so you avoid the labor cost, landfill fees, and construction mess. A trained crew typically completes a residential roof in 2–4 days; the four-way interlocking panels snap together, speed installation, and the lightweight aluminum means fewer workers and less structural stress during the work. Local Interlock installers serving this region since 2001 are familiar with Walworth County's contractor requirements and inspection standards.
Is a metal roof more sustainable than asphalt shingles?
Aluminum is approximately 95% recyclable, and Interlock panels reach end-of-life with full material value—aluminum scrap is worth money, so recycling is incentivized. By contrast, asphalt shingles—the majority of US residential roofing—are not recyclable and end up in landfills for centuries. Over a 50-year lifespan in Lake Como, a metal roof eliminates multiple tear-offs that asphalt requires; the single installation of Interlock, followed by recycling at true end-of-life, breaks the tear-off-to-landfill cycle that drives waste.
Does a reflective metal roof actually lower cooling costs in Wisconsin?
Yes—Interlock's energy-efficient colors reflect heat that asphalt absorbs, reducing attic temperature and cooling load during Lake Como's warm months. Initial solar reflectance reaches 0.55 (Aged Copper Penny) and thermal emissivity stands at 0.84, both verified by the Cool Roof Rating Council. While Wisconsin's 9.4°C mean temperature means cooling load is modest compared to southern states, summer peaks are real; a reflective roof can trim air-conditioning run-time and extend HVAC equipment life. The coating warranty of 30 years ensures reflectance stability—asphalt fades to dull gray in about 10 years, losing reflective benefit.
