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 Park Knoll

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

Will a metal roof handle Wisconsin's freeze-thaw cycles better than asphalt?

Yes—aluminum's crystalline structure doesn't absorb water, so it won't crack, curl, or degrade through the roughly 79 freeze-thaw days Park Knoll experiences annually. Asphalt absorbs moisture; when that water freezes and expands, it splits the shingles from within. Aluminum's oxide layer self-heals when scratched, and the 3105-H24 alloy (ASTM B209) has been installed from coastal salt-air homes to Antarctica since 1998, proving its durability through extreme thermal stress. Your roof won't deteriorate from repeated freezing—it'll outlast several generations of traditional shingles.

How does a metal roof perform under Park Knoll's snow load?

Metal roofing handles snow exceptionally well because it sheds weight rather than accumulating it. Park Knoll receives roughly 88 cm of snow annually, and the Interlock Slate or Shake profiles install at just 0.41–0.58 lb per square foot—so even a full snow load places minimal stress on your structure. The four-way interlocking panels prevent wind-driven snow from infiltrating seams, and because aluminum conducts heat differently than asphalt, ice dams form less readily. If you want additional snow retention, snow guards mount easily to the standing-seam profile without compromising the roof's integrity.

Can metal roofing withstand Park Knoll's wind gusts and storms?

The four-way interlocking aluminum panels are engineered to resist wind speeds up to 120 mph when installed to specification—well above the typical daily gusts of about 22 km/h that Park Knoll experiences, and even the extreme gusts reaching 96 km/h. Each panel locks on all four sides, so wind cannot peel or lift them. The warranty covers wind resistance explicitly, and because the panels weigh only 0.41–0.59 lb per square foot depending on profile, they experience less wind load than heavier materials. In a region where seasonal storms are common, this design means your roof stays secure without the vulnerability of traditional shingles.

Will hail damage a metal roof, and could I save on insurance?

No—Interlock metal roofing carries a UL 2218 Class 4 impact rating, the highest available, and the warranty even covers perforation from hailstones up to 1.5 inches. This non-combustible aluminum construction often qualifies homeowners for insurance discounts because claims for hail, wind, or impact damage are dramatically lower than with asphalt or traditional tile. Many insurers recognize that metal roofs reduce risk; contact your provider with the UL 2218 Class 4 rating to ask about premium reductions. Over a 40-year roof life in a region with unpredictable severe weather, these savings can offset a significant portion of installation costs.

What makes the Guardian Warranty different from a typical roof warranty?

The Guardian Warranty is a lifetime limited, non-prorated material warranty for the original owner—it covers rusting, rotting, splitting, cracking, curling, and loss of impact resistance without declining payouts as the roof ages. When you sell, it transfers to the next owner for 50 years from completion, adding genuine resale value. Most asphalt warranties are prorated and last only 15–25 years; by contrast, this aluminum roof could be the last roof you install. Because Park Knoll's freeze-thaw cycling (about 79 days annually) and 822 mm of rain create relentless conditions, having a truly non-prorated lifetime backstop means you're protected against the material failures that typically end a roof's life.

Can you install a metal roof directly over my existing shingles?

Yes—because the Interlock Mediterranean Tile, Shake, and Shingle profiles weigh only 0.41–0.59 lb per square foot (about 96% lighter than concrete or clay tile), they install over most existing roofs without structural reinforcement. This saves thousands in tear-off and disposal costs. Interlock Metal Roofing, serving the region since 2001, handles the assessment during your consultation to confirm your existing structure can support the overlay. The installation is straightforward: fasteners are driven through the old shingles into the roof deck, and the four-way interlocking panels begin locking together immediately. A typical residential roof in Park Knoll completes in 2–4 days, minimizing disruption.

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

Metal roofing requires minimal maintenance: an occasional gentle rinse to remove debris, especially after Park Knoll's roughly 88 cm annual snowfall. Unlike asphalt, which requires regular inspection for cracking, curling, and granule loss, aluminum won't split, rot, or deteriorate from moisture or freeze-thaw cycles. Unlike wood or cedar shingles, it needs no staining, sealing, or insect treatment. Unlike tile, it won't crack from impact or settlement. The ICC-ES ESR-1790 evaluation (reissued 2025) certifies this roof as CALGreen-verified for reduced maintenance. Over 40 years, the time and money you save on repairs, replacements, and preventive treatments vastly exceed what you'd spend on asphalt or traditional materials.

Can a metal roof actually help lower my cooling costs?

Yes—energy-efficient Interlock colors have thermal emissivity up to 0.84 and solar reflectance reaching 0.55 (Aged Copper Penny), meaning they reflect heat that asphalt absorbs and re-radiates into your home. Park Knoll receives about 3,128 sunshine hours annually, so even moderate reflectance compounds over time. The Cool Roof Rating Council rating confirms this effect under real-world conditions. In summer, a reflective metal roof can reduce attic temperature by 20–30°F compared to dark asphalt, lowering your cooling load and air-conditioning runtime. Combined with proper attic ventilation, this translates to measurable savings on your energy bills, especially during the region's warmer months.

What roof styles are available, and do they look like real slate or cedar shake?

Interlock offers five profiles: Slate, Cedar Shingle, Shake, Standing Seam, and Mediterranean Tile—each engineered to replicate the visual depth and texture of the traditional material it represents. The Slate profile mimics dimensional roofing stone; the Cedar Shingle and Shake profiles capture the irregular butt lines and shadow play of wood; the Tile profile echoes curved clay barrel tiles; and Standing Seam delivers clean, modern lines. Because these are aluminum panels with precision stamping and a 30-year fade-resistant Alunar finish, they hold their appearance far longer than wood, which weathers and grays. From street view, the authenticity of these profiles makes a genuine visual statement about your home's character—and they perform with metal's durability, not wood's vulnerability to rot, insects, or fire.

Who installs Interlock metal roofing in Park Knoll, and what experience do they have?

Interlock Metal Roofing has served the Park Knoll and Milwaukee County region since 2001, installing these four-way interlocking aluminum panels across residential and commercial properties. The company knows local weather patterns—the roughly 79 freeze-thaw days, 822 mm of annual rainfall, and gusts reaching 96 km/h—and designs installations accordingly. Their familiarity with building codes (ICC-ES ESR-1790 compliance) and local permitting streamlines your project. They perform on-site assessments to confirm overlay feasibility, handle fastening and interlocking precisely to achieve the 120 mph wind warranty, and stand behind workmanship. For a 40-year investment, having a local, established installer who understands your climate and will service the roof for decades is invaluable.

Is a metal roof a good choice for Park Knoll’s climate?

Yes. Park Knoll averages about 88 cm of snow, 822 mm of rain, roughly 79 freeze–thaw days a year, with peak wind gusts near 96 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.
