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 Riverview

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

How does a metal roof handle 120+ centimeters of snow per year in Wisconsin winters?

Interlock's four-way interlocking aluminum panels shed snow effectively while resisting the ice damming that damages asphalt shingles. The lightweight design—the Slate profile at just 0.41 lb/sq ft—means no structural reinforcement is needed, even under Riverview's typical 120 cm annual snowfall. The panels' smooth, hard surface prevents snow adhesion better than granulated asphalt, and the warranty covers wind gusts up to 120 mph, handling the region's recorded gusts near 98 km/h. Optional snow guards can be added for controlled melting. Over 80 freeze-thaw cycles annually won't degrade aluminum—it's the material itself that keeps performing season after season, not relying on a coating to prevent deterioration like asphalt does.

Why does freeze-thaw cycling in Wisconsin hurt asphalt roofs but not aluminum?

Asphalt and wood absorb moisture, expand when frozen, and crack when thawed—a cycle that repeats roughly 81 times yearly in Riverview. Aluminum doesn't absorb water, so freeze-thaw has no mechanical effect on the material itself. The Alunar 70% PVDF fluorocarbon finish protects both sides of each panel with a 30-year warranty against chalking and fading, meaning the coating resists the UV and thermal stress Riverview's 3,030 sunshine hours and seasonal temperature swings inflict. Interlock's ESR-1790 ICC-ES evaluation (reissued 2025) confirms the system's durability under Wisconsin's climate. The result: your roof's integrity doesn't degrade with each winter thaw, eliminating the premature aging that forces asphalt replacement every 15–20 years.

Does hail damage metal roofing, and can I get insurance breaks in Riverview?

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 proven durability often qualifies homeowners for insurance discounts; contact your carrier with the UL 2218 documentation. Riverview's hail risk is lower than the Great Plains, but severe thunderstorms do occur regionally. Unlike asphalt shingles, which fail at lower impact speeds and then leak internally, aluminum's hardness and the four-way interlocking design mean impacts don't compromise the roof seal. The same engineering that handles gusts near 98 km/h in this region handles hail—it's all about the material's inherent strength and the panel system's redundant protection. Check with your agent; the numbers often work in your favor.

Is metal roofing worth the upfront cost if I'm staying in my Riverview home long-term?

If you plan to stay 20+ years, metal roofing becomes the last roof you install. Asphalt requires replacement every 15–20 years; Interlock's Guardian Warranty is lifetime limited, non-prorated for the original owner, covering rusting, rotting, splitting, cracking, curling, and loss of impact resistance. Over 40 years, you'll typically replace asphalt twice and pay for tear-off disposal costs—asphalt shingles end in landfills. Interlock's aluminum is roughly 95% recyclable and installs over most existing roofs, avoiding tear-off expense. The Alunar 30-year coating warranty and ESR-1790 compliance confirm long-term performance in Wisconsin's freeze-thaw climate (about 81 cycles yearly). The higher initial cost is offset by one installation, no maintenance, no future replacement cycles, and resale value—essentially the cost of permanence rather than a consumable.

What exactly does Interlock's lifetime warranty cover, and how does it transfer?

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—essentially every failure mode that ends a roof's life. It's one-time transferable to the next owner for 50 years from completion, providing significant resale advantage. The Alunar coating itself carries a separate 30-year warranty against chalking and fading, verified by ASTM testing. This structure reflects aluminum's proven durability: Interlock has manufactured panels since 1998 and installed them from coastal salt-air homes to an Antarctic research station, proving the material and system work everywhere. In Riverview's 653 mm rain and 120 cm snow annually, the warranty isn't just marketing—it's backed by real-world evidence across climates far harsher than Wisconsin.

How long does installation take, and can you install over my existing roof?

Installation timeline depends on roof size and weather, but a typical residential job takes 3–5 days. Interlock installs over most existing roofs without tear-off—the lightweight panels (Slate at 0.41 lb/sq ft, Shake at 0.58, Tile at 0.59) weigh roughly 96% less than concrete or clay tile, so no structural reinforcement is needed. This saves labor and disposal costs. The four-way interlocking panels install panel-to-panel, creating a sealed, unified surface that sheds Riverview's 653 mm annual rainfall and resists 98 km/h gusts through mechanical locking, not fasteners alone. Interlock Metal Roofing has served this region since 2001, so scheduling and local permit coordination are straightforward. Ask about your specific structure during your consultation—a licensed installer can confirm whether over-roof installation applies to your home.

Is metal roofing fire-safe, especially in a wooded area near Riverview?

Yes. Interlock's aluminum is non-combustible, and Class A fire classification is available—the highest fire rating for roofing materials. Aluminum cannot sustain combustion, so it won't ignite or contribute fuel to a fire. This matters in Wisconsin's residential areas where brush and timber are common. The ICC-ES evaluation report ESR-1790 (reissued 2025) confirms the system meets International Building Code and IRC fire requirements, and CALGreen verification documents that the roof's non-combustible nature reduces ongoing fire risk and maintenance burden. Unlike asphalt or wood shakes, which can ignite or continue burning, metal roofing serves as a passive fire defense—it simply won't burn. If you're in a fire-prone microclimate or considering future insurance savings, Class A certification is a concrete safety advantage.

How much maintenance does metal roofing really need in Wisconsin?

Virtually none. Unlike asphalt, which requires inspection and repair every few years as granules degrade, or cedar and tile, which rot and crack, aluminum requires no coating touch-ups, seal replacement, or regular maintenance. The Alunar 70% PVDF finish is engineered to resist Riverview's 3,030 annual sunshine hours and freeze-thaw cycling without degradation. Debris—leaves, branches—rinses off with rain or can be swept away; the hard aluminum surface won't degrade from moisture exposure the way wood or asphalt does. CALGreen verification confirms the system's reduced maintenance profile. Over a 40-year lifespan, the labor and material cost of maintaining asphalt or tile roofing typically exceeds the installation cost; Interlock's design eliminates that burden entirely. You get a roof that performs without constant intervention.

Does a metal roof really reduce cooling costs, or is that overstated?

energy-efficient Interlock colors are Cool Roof Rating Council rated with thermal emissivity up to 0.84 and initial solar reflectance up to 0.55 (Aged Copper Penny profile), meaning they reflect heat that dark asphalt absorbs. In summer, this reduces attic temperatures and cooling load. Riverview averages 3,030 sunshine hours annually—more than enough for reflective coatings to make a measurable difference, especially on south and west-facing roofs. The effect is modest in Wisconsin compared to southern climates, but real: you'll notice lower AC runtime on hot days and more stable interior temperatures. The payback isn't dramatic unless you're in a very sunny area, but combined with the roof's longevity and other durability advantages, the energy benefit is genuine. Choose a lighter color profile if cooling efficiency matters to you—the reflectance numbers are verified by CRRC testing, not estimation.

How does a metal roof handle Riverview's winter wind gusts and storms?

Interlock's four-way interlocking aluminum panels are warranted to resist wind speeds up to 120 mph (193 km/h) when installed to specification—well above Riverview's recorded gusts near 98 km/h. The mechanical interlock creates a unified panel surface that distributes wind load across the entire roof rather than relying on individual fasteners, which can loosen or tear shingles. Each panel locks to its neighbors on all four sides, so wind pressure can't find seams or edges to lift. This design has proven itself in coastal installations and Antarctic conditions where wind stress is extreme. Combined with the panels' lightweight design (Slate at 0.41 lb/sq ft) and flexibility, the roof moves slightly with wind pressure rather than resisting it rigidly—a property that reduces stress on fasteners and the structure itself. Wisconsin's wind climate won't stress an Interlock roof; it's engineered for far worse.

Is a metal roof a good choice for Riverview’s climate?

Yes. Riverview averages about 131 cm of snow, 653 mm of rain, roughly 81 freeze–thaw days a year, with peak wind gusts near 98 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.
