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 Oak Hill

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

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

Metal roofing's smooth interlocking surface sheds snow and ice far more effectively than asphalt, which traps moisture and promotes ice dams. Oak Hill receives about 88 cm of snow annually across roughly 81 freeze–thaw days, creating conditions where ice dams can crack asphalt shingles and cause leaks. Interlock's four-way interlocking aluminum panels lock together seamlessly, preventing water infiltration even when ice forms at the eaves. The lightweight design (Shingle profile at 0.41 lb/sq ft) means no structural strain from heavy snow accumulation, and you can add snow guards without reinforcement. Aluminum's oxide layer remains intact through repeated freeze-thaw cycling, unlike asphalt which becomes brittle and cracks in those same conditions.

Why does freeze-thaw cycling damage some roofs but not aluminum?

Freeze-thaw damage occurs when water enters a material, freezes, expands, and cracks it from inside. Asphalt absorbs moisture and fails this way; wood shingles rot and split. Aluminum cannot rust or rot because it contains no iron, and its oxide layer is impermeable to water absorption. Oak Hill experiences about 81 freeze–thaw days per year with mean temperatures around 9°C—ideal conditions for this cycle. Interlock's roofing-grade 3105-H24 and 3003-H24 aluminum alloy (ASTM B209) remains dimensionally stable through unlimited freeze-thaw. Even if the coating scratches in winter, the aluminum's oxide layer self-heals, preventing corrosion. This is why Interlock systems have been installed from coastal homes to Antarctica: the material itself thrives where water and temperature extremes meet.

I've heard metal roofs rust—does that apply to aluminum?

Steel roofs rust; aluminum cannot, because aluminum contains no iron. The difference is chemical: iron oxidizes into rust, a crumbly compound that destroys the material. Aluminum oxidizes into a thin, transparent oxide layer that actually protects what's underneath and self-heals when scratched. Interlock uses roofing-grade 3105-H24 and 3003-H24 aluminum alloy (ASTM B209) with a Alunar® 70% PVDF fluorocarbon coating applied to both sides—extra insurance in humid or salt-air environments. For Oak Hill's 775 mm annual rainfall and 20 km/h average winds with gusts to 100 km/h, this dual-coat approach means corrosion is not a concern. The material has been performing identically in coastal British Columbia salt-air since 1998 and arctic research stations, proving aluminum's immunity across extreme climates.

Can a metal roof handle Wisconsin's wind and ice-laden gusts?

Interlock's four-way interlocking aluminum panels are warranted to resist wind speeds up to 120 mph (193 km/h) when installed to specification. Oak Hill sees typical daily-max winds around 20 km/h with gusts reaching 100 km/h—well within this margin. The interlocking design means each panel locks to its neighbors on all four sides, so wind cannot pry panels loose or cause cumulative lift. Unlike asphalt shingles, which rely on adhesive (weakened by freeze-thaw cycling), or standing-seam systems with fewer contact points, Interlock's geometry distributes lateral stress across the whole roof plane. When ice storms add weight and wind gusts spike, the panel matrix stays unified. The warranty covers the system as installed, giving you documented assurance that the roof won't fail under the wind loads your region actually produces.

Will my homeowners insurance recognize a metal roof's hail rating?

Interlock holds a UL 2218 Class 4 impact rating—the highest available—and the warranty even covers perforation from hailstones up to 1.5 inches. Many insurance companies recognize this rating and may offer premium discounts because metal roofs in this category rarely file hail claims. While Oak Hill's 10-year climate normals don't detail hail frequency, the UL 2218 Class 4 certification is underwritten by Intertek (listing 33876) and is recognized nationwide by underwriters. Contact your insurer directly with the UL 2218 Class 4 designation and Interlock's specifications to confirm your discount eligibility. The aluminum material itself doesn't dent like asphalt shingles, so even smaller hail causes no damage. This combination—third-party impact testing plus the material's hardness—is why some homeowners see insurance savings that partially offset the roof cost over time.

Can a metal roof reduce cooling costs in Wisconsin?

Yes. Interlock's energy-efficient colors achieve thermal emissivity up to 0.84 and initial solar reflectance up to 0.55 (Aged Copper Penny color), measured to Cool Roof Rating Council standards. These values mean the roof reflects heat that asphalt absorbs, keeping your attic and upper floors cooler during warm months. Oak Hill receives about 3074 sunshine hours per year and typically stays cool (mean 9°C), but spring, summer, and early fall benefit measurably from reflective coatings. When your air conditioning doesn't work as hard, you save energy and money—the payback compounds over decades. Unlike asphalt, which darkens with age and loses reflectance, Interlock's Alunar® 70% PVDF fluorocarbon coating is warranted 30 years against fading (ASTM D4214/D2244 measured), so the energy savings don't degrade. For a roof lasting 50+ years, maintaining reflectance for 30 of them is a substantial climate-control advantage.

Do I need to reinforce my house to install a metal tile roof?

No. Interlock's Mediterranean Tile profile weighs about 0.59 lb/sq ft—roughly 96% lighter than concrete or clay tile—so no structural reinforcement is required. Most homes can install it directly over existing asphalt without engineer approval. This matters in Oak Hill because it eliminates thousands of dollars in structural work and timelines. Concrete tile weighs 10–15 lb/sq ft; aluminum tile weighs under 0.6 lb/sq ft. The difference is enormous: your roof trusses, walls, and foundation feel the weight of gravity every day, and lighter loads mean longer structural life for the house itself. Since the material is so light, installation is faster, labor costs drop, and you can cover existing roofs without tear-off (keeping debris out of landfills). The ICC-ES evaluation report ESR-1790 confirms this lightweight profile meets IBC/IRC code even on older residential framing, so code inspection is straightforward.

What's the real lifespan of an Interlock metal roof, and what does the warranty cover?

The Guardian warranty is a lifetime limited, non-prorated material warranty to the original owner—covering rusting, rotting, splitting, cracking, curling, and loss of impact resistance. It's also one-time transferable to the next owner for 50 years from completion, a term that addresses nearly all buyer concerns in real estate. In practice, Interlock systems installed since 1998 in coastal salt-air and extreme climates show no degradation of the core material. The roofing-grade aluminum (ASTM B209) and Alunar® 70% PVDF coating (30-year fading warranty, ASTM D4214/D2244) are the lifespan limiters, and 30+ years is conservative—the material goes far longer. For Oak Hill's 81 freeze–thaw days and 775 mm rain annually, this warranty reflects real-world confidence. You're buying the last roof you'll need on that house and potentially the next owner's peace of mind too.

How much work is it to maintain a metal roof compared to asphalt or tile?

Interlock requires almost no maintenance. Unlike asphalt shingles—which degrade visibly every year in Oak Hill's 81 freeze–thaw cycles and need periodic inspection and repair—aluminum panels don't splinter, curl, or leak. Unlike wood shakes, which rot and require treatment. Unlike concrete tile, which cracks and needs repointing. Interlock's four-way interlocking design and self-healing aluminum oxide layer mean water cannot enter, and the Alunar® 70% PVDF coating is UV-stable (30-year warranty). You clear gutters, inspect flashing annually (standard for any roof), and that's it. The CALGreen verification confirms Interlock qualifies as a reduced-maintenance material. Over a 50-year lifespan, this translates to decades without contractor visits, roof coatings, or shingle replacement. Lower maintenance also means lower total cost—the premium material price shrinks when you account for what you don't spend on repairs.

Does Interlock have a local installer in the Oak Hill area?

Yes. Interlock Metal Roofing has served the region since 2001 and covers Oak Hill and surrounding Jefferson County. A local installer means faster response, familiarity with local building codes and permit processes, and knowledge of how the region's climate—775 mm annual rainfall, 88 cm snow, gusts to 100 km/h, and 81 freeze–thaw days—affects installation technique. They can assess your existing roof for compatibility (whether you can install over it or need tear-off), explain warranty registration, and ensure the system is installed to specification so the 120 mph wind warranty and UL 2218 Class 4 impact rating apply. Local installers also carry service relationships with suppliers, reducing lead times if any repair is ever needed. Contact the installer directly to request a site visit, estimate, and timeline—they'll walk you through the entire process specific to your home and neighborhood.

Is a metal roof a good choice for Oak Hill’s climate?

Yes. Oak Hill averages about 88 cm of snow, 775 mm of rain, roughly 81 freeze–thaw days a year, with peak wind gusts near 100 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.
