Interlock® Aluminum Roofing — all-climates performance specs for Lafayette, 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 Lafayette
The following metal roofing FAQs are designed specifically for homeowners in Lafayette, 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 Lafayette.
How does a metal roof handle the 82 cm of snow Lafayette gets each winter?
Interlock's four-way interlocking aluminum panels shed snow efficiently while staying anchored—they're warranted to 120 mph wind, so they'll hold through Lafayette's typical gusts up to 95 km/h without panel creep. The lightweight design (Slate at 0.41 lb/sq ft) eliminates the structural strain that heavy slate or concrete tile would impose, so you can install it directly over most existing roofs without reinforcement. Snow slides cleanly; ice dams form less readily on smooth metal than on asphalt. With about 84 freeze-thaw cycles annually in Walworth County, the aluminum's ability to expand and contract without cracking or splitting—unlike wood shakes or concrete—protects your investment through decades of seasonal swings.
Why does freeze-thaw weathering matter for roofing in Wisconsin, and how does aluminum respond?
Walworth County averages 84 freeze-thaw days per year—repeated water absorption and expansion that cracks asphalt, rots wood, and splinters shakes. Aluminum doesn't absorb water and contains no iron, so it cannot rust or rot. Its oxide layer self-heals when scratched, preventing corrosion channels from forming. The Alunar 70% PVDF fluorocarbon finish (warranted 30 years against chalking) seals both sides of each panel, adding a second defense. Over 23 years of service since Interlock's 2001 launch in the region, this material has proven itself against the exact seasonal stresses that degrade traditional roofing within 15–20 years.
Why do some metal roofs rust and Interlock aluminum roofs don't?
Steel roofing rusts because steel contains iron, which oxidizes into rust when exposed to moisture and oxygen. Interlock roofing uses 3105-H24 and 3003-H24 aluminum alloy (ASTM B209)—aluminum contains zero iron and therefore cannot rust, period. Instead, aluminum forms a thin, invisible oxide layer that naturally heals when scratched, sealing out corrosion. Combined with the Alunar 70% PVDF coating on both panel surfaces, this dual protection is especially valuable in Walworth County's 857 mm of annual rainfall and damp Wisconsin air. Even in coastal salt-air installations, Interlock panels remain corrosion-free—a performance standard met since 1998.
Will hail damage my metal roof, and could it lower my insurance costs?
Interlock achieves UL 2218 Class 4 impact rating—the highest available—and the Guardian Warranty even covers perforation from hailstones up to 1.5 inches. This exceptional durability often qualifies homeowners for insurance discounts; check with your provider. Walworth County's wind gusts to 95 km/h sometimes accompany hail, but Interlock's four-way interlocking system keeps panels locked together, preventing uplift or separation. The Class 4 rating means the roof has absorbed impact energy that would dent or puncture asphalt shingles or slate. Many insurers recognize this resilience and reward it—it's worth asking your agent about premium reductions before you decide.
Can my existing roof structure handle a metal roof, or will I need expensive reinforcement?
No structural reinforcement is typically needed. Interlock's Mediterranean Tile profile weighs just 0.59 lb/sq ft—approximately 96% lighter than concrete or clay tile—and installs directly over most existing roofs. The Shake at 0.58 lb/sq ft and Slate at 0.41 lb/sq ft are lighter still. Because Lafayette receives about 82 cm of snow annually, that weight savings matters: a traditional tile roof would add 10–15 tons of dead load, requiring costly joist reinforcement; Interlock adds almost none. The ICC-ES evaluation report ESR-1790 confirms installation over existing decking is code-compliant (IBC/IRC, reissued 2025). A structural engineer rarely needs to be consulted for a residential retrofit.
How well does a metal roof stand up to Wisconsin wind gusts?
Interlock is warranted to resist wind speeds up to 120 mph (193 km/h) when installed to specification. Lafayette's typical wind gusts reach 95 km/h, leaving a safety margin of more than 50%. The four-way interlocking panel system locks each sheet to its neighbors on all edges, preventing the separation and uplift that damage shingle roofs in storms. The lightweight design (0.41–0.59 lb/sq ft depending on profile) means less material for wind to grab, yet the mechanical interlock is what truly matters. Walworth County's 19 km/h mean wind speed is modest, but seasonal gusts have tested metal roofing in Wisconsin repeatedly; Interlock's 23-year regional service record confirms reliable performance.
Will a metal roof actually reduce my cooling costs in summer?
Cooling costs in summer depend on roof color and reflectance. Interlock's energy-efficient colors reflect heat rather than absorbing it like asphalt—initial solar reflectance reaches 0.55 (Aged Copper Penny) with thermal emissivity of 0.84, both verified by the Cool Roof Rating Council. Lafayette gets about 3,120 sunshine hours yearly; that reflected solar energy directly reduces air-conditioning load. A cool metal roof stays 30–40°F cooler than dark asphalt under midday sun. Over a 50-year roof life, the energy savings can total thousands of dollars. Combined with the metal's durability—you won't replace it in 20 years—the lifetime cost per year of cooling is substantially lower than asphalt.
How long will my metal roof last, and what does the warranty actually cover?
The Guardian Warranty is a lifetime limited, non-prorated material warranty for the original owner—it covers rusting, rotting, splitting, cracking, curling, and loss of impact resistance. It's one-time transferable, giving the next owner 50 years from completion. This depth of coverage reflects the material's proven durability: Interlock has manufactured since 1998, installed from coastal salt-air homes to Antarctica, and fielded roofs through 84 annual freeze-thaw cycles in Walworth County. Most homeowners never file a claim because aluminum simply doesn't fail in the ways asphalt, wood, or tile do. When you sell, the warranty transfers—increasing buyer confidence and resale appeal.
Is a metal roof worth the upfront cost compared to asphalt shingles?
The comparison is lifetime cost, not first cost. Asphalt typically lasts 15–20 years; you'll replace it twice while your metal roof delivers 50+ years. Interlock's lightweight profiles (0.41–0.59 lb/sq ft) often install over existing shingles—avoiding tear-off labor and landfill disposal costs. You skip the maintenance cycle: no algae cleaning, no flashing repairs, no periodic re-sealing that asphalt demands. Insurance discounts for Class 4 hail rating reduce annual premiums. Energy savings from energy-efficiency reflectance (0.55 solar reflectance, 0.84 emissivity) trim cooling costs year after year. Over 50 years, the total out-of-pocket cost per year becomes competitive with—or lower than—asphalt. That's the value: this is the last roof you'll buy.
Is my home safer with a metal roof, or is that marketing hype?
It's neither hype nor irrelevant—it depends on your risk tolerance and local code. Interlock aluminum is non-combustible and meets Class A fire classification, the highest available. The ICC-ES evaluation report ESR-1790 confirms code compliance under IBC/IRC standards (reissued 2025). In Walworth County, Class A roofing is not mandated for residential homes, so it's optional. However, non-combustible roofing provides real protection: it won't ignite from flying embers during a wildfire or structure fire, and homeowners insurance companies recognize this lower risk. If you value maximum fire safety or live near forested areas, the aluminum option eliminates one failure mode entirely. If fire risk isn't a personal priority, other benefits (durability, energy savings) may matter more to your decision.
