Review: July 20, 2016Completion: June 9, 2016

Hello Greg, I just had to drop you a line to tell you how pleased we are with the Interlock Roofing System that was installed last week. I have to admit that as good as I was hoping it would look, it turned out to be so much better than I had even hoped. We couldn’t be prouder of how our house looks now; the new roof is visually stunning. We can now breathe a huge sigh of relief, knowing that we’ll never again have to go out into the yard and pick up the pieces of asphalt shingles that would blow off of the roof after a storm or a high wind day. To boot, the very day after the roof was completed, we had someone who identified himself only as “your nosy neighbor from 10 miles down the road,” who stopped, knocked on our door and started asking questions about the roof. He was shocked to hear that it was a metal roof. He thought that we had installed a slate roof! He was very interested to hear all the facts about the roof, and suddenly I became Interlock Roofing’s most avid salesman. I brought out your business card so that he could take a picture of it with his cell phone, and he said he’d be contacting you soon. I’ve also been talking about the roof with some of the guys at work who had seen the before and after pictures that I brought in, and I’m sure that you will be hearing from some of them in the future too. Now, as much as I couldn’t be happier with contacting you and doing business with you, I have to tell you that even you will have to take a back seat to the super awesome job of your installers, Jesse and his team. To say we were blown away by these guys would be the understatement of the century. They came in like a whirlwind and started doing their thing and made astounding progress in such a short period of time, it blew us away. Jesse himself is such a great face to have attached to your company. He is professional, knowledgeable, and so personable that we knew in an instant that we were in good hands with him and his team. All of his team members were that way, and honestly, the hardest working group of guys that you will ever witness. We expected it to take anywhere from 5 days to a week to get our whole roof done. These guys had it done in 2 days and a couple of hours, and they left no stone unturned in doing the A-1 job that was promised. They even fixed a couple of cosmetic items on our existing siding to boot! What a great bunch of guys. And let me reiterate one more time,…Interlock, as a company, should feel confident and proud to have Jesse and his team representing them. I’m positive you will never find a better team to install your product than them. Again, thank you for the product and the work that you’ve done. You now have not only a very satisfied customer in us, but you also have a couple of very enthusiastic ambassadors for Interlock Roofing Systems.

Review: June 17, 2017Completion: February 17, 2017

I have made, and continuously still make, numerous recommendations to family & friends to install a Interlock roof. And, I have produced pictures on demand that I stored on my smart phone. If possible, I would be appreciative if I could get the drone footage that Jesse had taken after the finishing of the installation. I believe it would be a great selling point coming from a true customer to help propel the Interlock name. There are just a couple areas on the roof that the installation crew could have touched-on during the installation, but overall the roof looks simply amazing. Quality certainly displays the professionalism the installers had put into their work. Since the installation of our new roof, we have received numerous compliments from many of our neighbors that walk around our subdivision, plus a handful of neighbors in the adjoining subdivisions. Many questions have been asked with many answers given. We are definitely happy with our new Interlock roof. We have NOT once questioned or second guessed our decision to install an Interlock roof. It is one of the best decisions we have ever made for re-investing in our home...Thank you, Interlock!

Review: June 8, 2008Completion: November 30, 2007

I never really thought I could be thrilled about a roof, but I have to tell you; our new Interlock roof is beautiful! It adds true elegance to our home. We know it adds value as well, and the fact that we will never need to re-roof again is a definite advantage. Everyone within our organization, from the initial phone contact to the installation crew, was courteous and pleasant to work with. The install went smoothly and the crew kept the site clean from beginning to end. Everybody we have shown our Interlock roof to has seemed quite impressed also. We would (and in fact have already done so) recommend Interlock Roofing to others.

Review: July 20, 2016Completion: November 13, 2008

Excellent roof! Looks good! The installers were courteous and professional. Put the tarp all around the house and kept the site very clean. I was impressed with their super service. They bent over backward to please us. The A-Team of Roofing! When it rains, it is NOT any louder, and we are in a wind zone, and shingles have not blown off, and we have had the roof since 2008. The snow slides off, too! And the salesman knows his product and explains it well. It will add value to the house. Unlike asphalt, that's like tar and paper, and doesn't hold up. The Interlock Lifetime Roof is super durable!d Greg Weber the salesman, knows his product and explains it well. It will add value to the house. Unlike asphalt, that’s like tar and paper and doesn’t hold up. The Interlock Lifetime Roof is super durable!

Review: May 17, 2017Completion: August 10, 2009

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.

Review: May 16, 2017Completion: July 31, 2008

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!

★★★★★
Review: April 10, 2017Completion: March 17, 2015

I love the roof! It looks great, and the squirrels that we’re crawling all over my old asphalt roof slide right off it. The snow slides off, too. I hope to get some $500 referrals. The crew was terrific, hardworking, courteous, polite, and clean.

Review: April 23, 2009Completion: May 5, 2008

Drip, drip, drip. This is not a sound you want to hear at 3:30 am… in bed… coming from your attic… in the dead of winter. A quick peek in the attic confirmed my worst fears, the ice dam on the roof was allowing melted water to seep through the crappy asphalt shingles and into the house. We called a local contractor and had the ice dam removed, but this didn’t fix the underlying problem that our current roof was cheap and damaged. My wife and I moved into a beautiful three-story brick Tudor on Madison’s near west side in the fall of 06′. It was perfect in that it had been beautifully remodeled with gorgeous woodwork, marble, and stunning attention to detail, with the exception of the roof. We had decided that, barring any unforeseen circumstances, this was the house we were going to stay in until retirement, so why not invest in a metal roof. After a couple of weeks of research and interviewing, we settled on Interlock. Part of the choice was made on the quality of the product, and part was made on the salesmanship of the rep, Chuck. Work started and except for some problems with the weather, things progressed smoothly. We were especially impressed with the steps the crew took in regard to safety, and our stay-at-home neighbor told us about how exciting the crew was, “you’re definitely getting your money's worth,” was her exact quote. At the end of the job, the crew even emptied all the trash we had pulled out of the attic for us. Now that’s service! After everything is said and done, we’ve been able to cap off our gorgeous house with an equally gorgeous roof.

Review: April 16, 2026Completion: February 20, 2009

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.

Review: May 16, 2017Completion: September 24, 2014

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.

Review: May 10, 2017Completion: March 20, 2017

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!

★★★★★
Review: April 10, 2017Completion: February 23, 2017

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 Highland Acres

The following metal roofing FAQs are designed specifically for homeowners in Highland Acres, 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 Highland Acres.

How does a metal roof handle 128 cm of snow per year in Wisconsin winters?

Interlock's four-way interlocking aluminum panels shed snow reliably because the smooth, slippery surface prevents accumulation that causes ice dams on asphalt. With about 120 cm annual snowfall and 83 freeze-thaw days in Highland Acres, the lightweight design (Slate at 0.41 lb/sq ft) means no structural reinforcement is needed, even under heavy snow load. Aluminum's oxide layer remains stable through repeated freeze-thaw cycles, unlike materials that crack or warp. Snow guards are available if you want to control shedding near walkways.

Why does freeze-thaw cycling in Wisconsin winters matter for my roof choice?

Highland Acres experiences about 83 freeze-thaw cycles annually—a genuine test of material durability. Aluminum cannot rust or rot, so the repeated wet-freeze-thaw-dry pattern that degrades asphalt, wood, and steel has no grip on it. The self-healing oxide layer on Interlock's 3105-H24 aluminum alloy actually strengthens with oxidation rather than deteriorating. The Alunar 70% PVDF coating (warranted 30 years) protects against salt intrusion in the few areas near Lake Michigan, ensuring your panels perform identically in year 83 as year one.

Can aluminum roofing rust in Wisconsin's climate?

No—aluminum contains no iron, so rust is chemically impossible. When the aluminum oxide layer is scratched by installation, weather, or debris, it self-heals automatically; the exposed metal re-oxidizes, sealing itself. This matters in Highland Acres because annual rainfall of about 747 mm, combined with 18 km/h winds gusting to 91 km/h, means constant moisture and debris contact. Interlock's roofing-grade 3105-H24 and 3003-H24 alloys (ASTM B209) are designed for exactly this: coastal homes and extreme environments worldwide. Steel roofing requires protective coatings that degrade over time; aluminum's protection is built into the material itself.

Will a metal roof hold up to Highland Acres wind and gusts?

Yes. Interlock's four-way interlocking panels are warranted to resist sustained winds up to 120 mph (193 km/h) when installed to specification. Highland Acres typically sees gusts around 91 km/h—well within safe limits. The interlocking design means each panel is mechanically fastened and supported by its neighbors, distributing wind load across the entire roof rather than concentrating stress on individual fasteners. UL 2218 Class 4 impact rating (the highest available) demonstrates the panel's structural rigidity. For the occasional severe gust in Kenosha County, this engineering eliminates the flutter, uplift, or panel separation that homeowners sometimes fear with metal.

What's the hail rating on Interlock metal roofing, and does it affect my insurance?

Interlock panels carry UL 2218 Class 4 impact rating—the highest available—meaning they withstand 1.5-inch hailstones without perforation or loss of weather protection. That rating alone may qualify you for homeowner's insurance discounts; contact your agent with the ESR-1790 evaluation report. The Guardian warranty covers hail damage, so you're protected both by the roof's proven durability and by the manufacturer. In Wisconsin, severe hail is less frequent than wind or snow, but when it occurs, Class 4 aluminum outperforms asphalt, wood, and standard metal panels. Many homeowners recoup the upgrade cost through lower insurance premiums within 3–5 years.

Does a metal roof stay hotter in summer, or can it help me save on cooling?

Interlock's energy-efficient colors reflect rather than absorb heat, thanks to initial solar reflectance up to 0.55 and thermal emissivity of 0.84 (Cool Roof Rating Council rated). Highland Acres receives about 2946 sunshine hours yearly, so reflective coatings meaningfully reduce cooling load on sunny days. The contrast to asphalt is stark: asphalt absorbs heat and transfers it into the home; Interlock reflects it away. Even with about 128 cm snow cover in winter, you don't lose winter solar gain where you want it—the reflectance is balanced to maintain passive heating. Over a 50-year lifespan, the energy savings compound significantly, especially as cooling demand increases.

Is a metal roof light enough to install over my existing shingles without reinforcing the structure?

Yes. The Mediterranean Tile profile weighs only 0.59 lb/sq ft—about 96% lighter than concrete or clay tile—so it installs directly over most existing asphalt roofs without any structural reinforcement. Even the heavier Shake profile (0.58 lb/sq ft) creates minimal structural load. Highland Acres homes built to standard framing can support this weight easily. The advantage is clear: you avoid the cost and disruption of tear-off and disposal, you skip the structural engineer's report, and installation is faster. Interlock's ICC-ES evaluation (ESR-1790) explicitly permits install-over in most climates, confirming the engineering behind this lightweight aluminum approach.

How much maintenance does a metal roof really need compared to asphalt or tile?

Interlock requires minimal maintenance: occasional gutter cleaning and removing large debris. Unlike asphalt (which requires periodic re-sealing and loses granules over time), aluminum doesn't degrade chemically; the Alunar 70% PVDF coating (30-year warranty against fading) resists UV and weathering. Unlike wood shake (which splits and curls), aluminum doesn't absorb moisture or rot—even with 747 mm annual rainfall and 83 freeze-thaw days. Unlike tile (which cracks and requires replacement), aluminum flexes and remains intact. CALGreen-verified for reduced maintenance, Interlock outlasts the maintenance budget of competitive materials. Most owners report they rarely think about their roof after installation.

What does 'lifetime warranty' on a metal roof actually mean in plain terms?

Interlock's Guardian warranty is a lifetime limited material warranty (non-prorated for the original owner) covering rusting, rotting, splitting, cracking, curling, and loss of impact resistance. Non-prorated means there's no declining benefit over time—a claim at year 5 or year 45 receives the same coverage. It's transferable once: the second owner receives 50 years of protection from completion, giving the home exceptional resale appeal. This is exceptional: most roofing warranties either expire or decline over time. The warranty works because aluminum's durability is real, not marketing. Installed in 1998, Interlock roofs are still performing—a 27-year real-world track record supporting the promise.

Is metal roofing actually better for the environment than standard asphalt shingles?

Yes. Interlock's aluminum is approximately 95% recyclable and retains full value at end-of-life—it's melted down and re-used indefinitely without degradation. Asphalt shingles are single-use: tear-off generates landfill waste with no recovery value. Over a 50-year lifespan, you'll never replace an Interlock roof; you avoid five or six asphalt tear-offs, each sending tons to the landfill. The manufacturing carbon footprint is amortized over five decades, unlike asphalt replaced every 15–20 years. Highland Acres' 747 mm annual rainfall and 128 cm snow exposure means faster asphalt wear, accelerating that replacement cycle and waste accumulation. Choosing aluminum breaks the tear-off-to-landfill cycle entirely.

Is a metal roof a good choice for Highland Acres’s climate?

Yes. Highland Acres averages about 128 cm of snow, 747 mm of rain, roughly 83 freeze–thaw days a year, with peak wind gusts near 91 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.
