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 Holland

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

Does metal roofing handle Wisconsin snow and ice buildup better than asphalt?

Metal roofing's smooth, hard surface sheds snow and ice far more effectively than asphalt, which traps moisture and promotes ice dam formation. Holland averages about 105 cm of snow annually and experiences roughly 84 freeze-thaw cycles per year—conditions that make ice dams a real problem on traditional roofs. Interlock's four-way interlocking aluminum panels create a unified, slippery surface that allows snow to slide safely rather than accumulate at the eaves. You can add snow guards to any profile if you prefer controlled release, but many owners in heavy-snow climates find the natural shedding eliminates ice-dam callbacks entirely.

Will freeze-thaw cycles crack or damage an aluminum metal roof?

No. Aluminum expands and contracts uniformly with temperature swings, and it contains no water-absorbing materials that crack when frozen. Holland's 84 annual freeze-thaw days and roughly 105 cm of yearly snow create intense seasonal stress on asphalt and wood, but aluminum's roofing-grade 3105-H24 and 3003-H24 alloys (ASTM B209) were engineered precisely for this cycling. The material simply relaxes and recovers with each temperature change—the coating and substrate remain stable decade after decade. This durability is why Interlock has installed roofs from coastal salt-air homes to an Antarctic research station since 1998.

Can an aluminum roof rust, especially near Lake Michigan's salt air?

Aluminum cannot rust because it contains no iron—the element responsible for rust formation. Instead, aluminum develops a thin, self-healing oxide layer that actually protects the metal underneath. When scratched or damaged, this oxide reforms automatically, providing passive protection. Interlock adds a two-sided Alunar 70% PVDF fluorocarbon finish (warranted 30 years against chalking and fading per ASTM D4214 and D2244) for extra corrosion defense in salty environments. While Sheboygan County isn't coastal, this dual-layer protection means your roof faces no rust risk whatsoever—a major advantage over steel roofing or corroded fasteners that plague asphalt installations.

Can a metal roof survive Wisconsin's wind and storm gusts?

Yes. Holland experiences typical daily-max winds around 20 km/h with gusts reaching 99 km/h—well within the capability of Interlock's four-way interlocking system. The panels are warranted to resist wind speeds up to 120 mph (193 km/h) when installed to specification, and the interlocking mechanism (not fasteners alone) transfers lateral loads across the entire roof plane. This design philosophy is why Class 4 hail-rated metal roofs remain intact in storms that tear asphalt into confetti. The ICC-ES ESR-1790 evaluation confirms this performance under IBC/IRC building codes, giving you assurance that your roof won't fail when Wisconsin's worst weather arrives.

Will a metal roof lower my homeowner's insurance after hail damage happens?

Interlock achieves UL 2218 Class 4 impact rating—the highest available—and the warranty covers even perforation from 1.5-inch hailstones. Many insurers offer premium discounts for Class 4 roofs because the claims history is dramatically lower than asphalt. After a major hail event, you'll file a claim confident that your roof is unlikely to suffer damage requiring replacement. Contact your agent with your roof's UL 2218 Class 4 certification to explore discount eligibility; the non-combustible aluminum construction (Class A fire rating available) often qualifies for additional savings. Over a 50+ year roof life, those annual discounts compound into tens of thousands of dollars in recovered value.

Does an aluminum metal roof really save money on heating and cooling?

energy-efficient colors with thermal emissivity of 0.84 and solar reflectance up to 0.55 reduce cooling costs by reflecting heat that asphalt absorbs. Holland receives about 3127 sunshine hours annually, and while summers are moderate, every degree of cooling saves energy year-round. Cool Roof Rating Council certification means your roof actively cools your attic instead of baking it. On a 2000 sq ft roof, this translates to measurable utility savings, especially if you're replacing dark asphalt that converts sunlight directly into interior heat. The reflective coating is factory-applied and lasts the life of the roof—no paint maintenance required.

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

Metal roofing requires virtually no maintenance—no sealing, no patching, no pressure washing. Asphalt roofs need regular inspections, caulking of seams, and protective coatings to combat the 739 mm of annual rainfall and 105 cm of snow Holland receives. Concrete or clay tile requires periodic re-grouting and cracked-tile replacement. Interlock aluminum sheds rain and snow naturally, resists freeze-thaw without degradation, and the Alunar coating remains stable for 30 years (warranted per ASTM D4214/D2244). CALGreen-verified for reduced maintenance means environmental agencies recognize the labor and waste savings. You'll spend virtually nothing on upkeep—just occasional gutter cleaning, like any roof.

What warranty does Interlock offer, and how long will the roof actually 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 zero depreciation over time. If you sell, the next owner receives 50 years of transferable coverage from completion, adding tangible value to your property. Interlock has manufactured aluminum roofing since 1998, with installations in extreme climates from coastal salt air to Antarctica, demonstrating real-world longevity well exceeding 50 years. This is the only roof you'll likely install on your Holland home—a genuine multi-generational asset that survives the 84 annual freeze-thaw cycles and 105 cm of snow your region experiences.

Will I need to reinforce my roof structure to support a metal roof?

No structural reinforcement needed. Interlock's aluminum panels are extraordinarily light—the Slate profile installs at just 0.41 lb/sq ft, Shake at 0.58, and the Mediterranean Tile profile at about 0.59 lb/sq ft. That last figure is roughly 96% lighter than concrete or clay tile, meaning you can install it directly over most existing roofs without engineering upgrades. Asphalt shingles weigh more or less the same, so if your home already carries asphalt safely, metal installs with zero structural risk. Many Wisconsin homeowners save thousands in tear-off labor and disposal costs by installing directly over the old roof—the metal's weight isn't a burden; it's a bonus that simplifies the entire project.

How long does metal roofing installation take in Holland?

Installation timelines vary with roof size and complexity, but Interlock's interlocking panel system accelerates the process compared to tile or traditional shingles—panels cover more area per fastening operation and the system's simplicity reduces job-site errors. Many installations can proceed over an existing roof without tear-off, compressing the timeline further and eliminating landfill disposal. A typical residential project in the Holland area takes several days to two weeks depending on weather and roof pitch. Interlock's local installer has served the region since 2001 and understands Wisconsin's seasonal constraints—late spring through early fall offers the longest weather windows. You'll receive a detailed timeline during the consultation so you can plan around rainfall and the typical 20 km/h daily winds Sheboygan County experiences.

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

Yes. Holland averages about 105 cm of snow, 739 mm of rain, roughly 84 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.
