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 Wilmot Hills

The following metal roofing FAQs are designed specifically for homeowners in Wilmot Hills, 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 Wilmot Hills.

Does metal roofing handle heavy snow in Wisconsin? Won't it slide off?

Metal roofing handles snow load well, and Interlock panels won't shed snow unexpectedly when properly installed with snow guards. Wilmot Hills gets about 82 cm of snow annually across roughly 80 freeze-thaw days, creating conditions where ice dams form on weaker materials. The aluminum's light weight (the Slate profile installs at 0.41 lb/sq ft) means your home's structure carries less load, while the four-way interlocking design prevents panel separation under thermal stress. Snow guards keep accumulation where you want it, and the smooth surface actually reduces dangerous ice dam formation better than rough asphalt, which traps moisture and breaks down faster through repeated thaw-refreeze cycles.

Will my metal roof crack or fail from Wisconsin's freeze-thaw cycles?

No—aluminum's metallurgy actually improves in freeze-thaw climates because it has no water absorption and no internal expansion stress. With 80 freeze-thaw days per year in Wilmot Hills and 835 mm of rainfall, your roof faces serious cycling stress. Wood shakes split, asphalt becomes brittle, and concrete tile cracks. Aluminum 3105-H24 alloy simply contracts and expands uniformly without stress concentration. The Alunar 70% PVDF coating (30-year fade/chalk warranty per ASTM D4214) stays flexible through temperature swings, so it won't crack like paint on traditional materials. The Guardian Warranty explicitly covers cracking and splitting—a guarantee competitors cannot match.

Can aluminum roofing rust? What about salt air or road salt in winter?

Aluminum cannot rust because it contains no iron. Instead, it forms a microscopically thin, self-healing oxide layer that protects the metal underneath—even when scratched during installation or by branches. This is why Interlock has shipped panels from coastal salt-air homes to Antarctic research stations since 1998. In Wilmot Hills, where winter road salt is common and 835 mm of rain annually accelerates corrosion of steel products, aluminum's natural immunity becomes a major advantage. The roofing-grade 3105-H24 / 3003-H24 alloy is covered by a lifetime limited warranty against rusting, so if corrosion ever occurs, it's covered. Steel roofs—which do rust—don't offer that protection.

How strong does a metal roof need to be for Wisconsin wind gusts?

Wilmot Hills experiences wind gusts up to 99 km/h (about 62 mph) with typical daily winds around 20 km/h, so your roof needs serious hold-down strength. Interlock's four-way interlocking aluminum panels are warranted to resist wind speeds up to 120 mph (193 km/h) when installed to specification—nearly double the worst gusts you'll encounter. That warranty is backed by UL testing and doesn't depend on sealants that degrade over time; the mechanical interlock itself resists panel lift. Asphalt shingles rely on adhesive that weakens in Wisconsin's temperature swings, while standing-seam steel can separate at fastener points. This roofing's design prevents the gradual panel creep and blow-off failures common in older homes around your area.

Does metal roofing hold up to hail? Will my insurance rates drop?

Interlock panels earn UL 2218 Class 4 impact rating—the highest available—and the Guardian Warranty covers hail perforation from stones up to 1.5 inches. That's considerably stronger than asphalt or wood, which dent, split, or puncture in severe hail. Many homeowners report insurance premium reductions after installing metal roofing, though your specific discount depends on your carrier's underwriting. In Wilmot Hills, where thunderstorm risk is real across 3094 annual sunshine hours and frequent spring-summer weather changes, a non-combustible, impact-rated roof signals lower claim risk. Contact your insurer before installation to confirm discounts, but the Class 4 rating gives them confidence—backed by independent third-party testing, not marketing claims.

How long does metal roofing last, and what does 'lifetime warranty' actually mean?

The Guardian Warranty is a lifetime limited, non-prorated material warranty for you—covering rusting, rotting, splitting, cracking, curling, and loss of impact resistance. It transfers once to the next owner for 50 years from completion, so it protects your home and adds resale appeal. Most asphalt roofs last 15–20 years in Wisconsin's 80 freeze-thaw days and 82 cm snow load; metal roofing installs in 1998 in Delta, BC are still performing, spanning 27 years of coastal salt-air and severe cycling. Non-prorated means there's no percentage reduction in coverage over time—a rare commitment that reflects Interlock's confidence in aluminum's durability. This is the last roof most homeowners will buy, eliminating the tear-off-and-replace cycle every two decades.

Is metal roofing worth the upfront cost compared to asphalt in the long run?

Metal roofing costs more upfront but eliminates the recurring expense cycle. Asphalt fails in 15–20 years under Wisconsin's conditions (835 mm rain, 80 freeze-thaw days annually), forcing replacement, debris hauling, and reinstallation labor. Metal roofing lasts 40+ years with minimal maintenance, so you avoid 2–3 tearoffs over 60 years. When you factor labor, landfill fees, and material inflation, metal's upfront premium shrinks significantly. The Guardian Warranty transferability adds resale value—buyers pay for longevity. Additionally, energy-efficient profiles reflect heat that asphalt absorbs, reducing cooling costs in Wisconsin's 3094 sunshine hours. Total cost of ownership over your ownership period typically favors metal by a considerable margin once you stop replacing shingles every 15 years.

Can metal roofing really lower my cooling costs, or is that just marketing?

Metal roofing's energy benefit is measurable: energy-efficient Interlock colors achieve thermal emissivity of 0.84 and solar reflectance up to 0.55 (Aged Copper Penny), rated by the Cool Roof Rating Council. In Wilmot Hills, where you enjoy 3094 annual sunshine hours, those reflective qualities reduce the heat asphalt absorbs and radiates into your attic. Dark asphalt can reach 160–180°F on sunny days; reflective metal stays substantially cooler, cutting air-conditioning load during summer. Wisconsin summers are moderate, so cooling savings may not rival southern states, but the effect compounds over decades. Lower attic temperature also extends the life of insulation, wiring, and HVAC equipment. This isn't hype—reflectance is measured by independent standards (CRRC), and utilities sometimes offer incentives for Cool Roof installation.

How is metal roofing installed? Can you install it over my old roof?

Installation typically takes 2–5 days depending on roof size and complexity. Panels interlock horizontally and vertically, fastening to the deck with stainless-steel fasteners that move slightly as the roof expands and contracts—preventing the leaks that occur when rigid fasteners crack surrounding material. One major advantage: the Tile profile weighs only about 0.59 lb/sq ft, making it roughly 96% lighter than concrete or clay tile, so most existing roofs can support it without structural reinforcement. You can install over asphalt shingles if decking is sound; otherwise, underlayment and flashing are sealed just like traditional roofing. Interlock has served the region since 2001, so local installers understand Wisconsin's climate-specific details: snow guards, ice-dam prevention, and freeze-thaw expansion gaps. Always hire an ICC-ES ESR-1790 certified installer for warranty validity.

Is there a local metal roofing installer in Wilmot Hills I can trust?

Interlock Metal Roofing has served your region since 2001 and knows Wisconsin's climate demands firsthand. With 835 mm rainfall, 82 cm snow, 80 freeze-thaw days, and gusts to 99 km/h, your roof faces real stresses—not theoretical ones. A local installer who has been in business over 20 years understands what works: snow guard placement to prevent slide-off, flashing details that shed water properly, fastener choices that won't loosen through thermal cycling. They can walk you through the five profile options (Slate, Cedar Shingle, Shake, Standing Seam, Mediterranean Tile), explain the ICC-ES ESR-1790 compliance, and ensure your installation qualifies for the Guardian Warranty. Avoid distant contractors who've never installed in a freeze-thaw climate—detail mistakes void coverage and cost thousands in repairs.

Is a metal roof a good choice for Wilmot Hills’s climate?

Yes. Wilmot Hills averages about 82 cm of snow, 835 mm of rain, roughly 80 freeze–thaw days a year, with peak wind gusts near 99 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.
