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 Lake Shangrila Terrace

The following metal roofing FAQs are designed specifically for homeowners in Lake Shangrila Terrace, 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 Lake Shangrila Terrace.

How does a metal roof handle Wisconsin snow and ice damming?

Metal roofs shed snow and ice far more effectively than asphalt because the smooth, hard surface and four-way interlocking panels create no grip for ice dams to form. Lake Shangrila Terrace receives about 82 cm of snow annually and experiences roughly 80 freeze-thaw cycles per year—conditions that wreak havoc on asphalt by cycling water into cracks. Interlock's aluminum stays rigid through every thaw, preventing the cupping and curling that trap meltwater. Snow slides cleanly off, eliminating the weight stress and ice-dam backup that damage gutters and interior walls. Optional snow guards keep snow from sliding unexpectedly into walkways.

Will freeze-thaw cycles damage aluminum metal roofing?

No—freeze-thaw is actually where aluminum roofing excels against traditional materials. With 80 freeze-thaw days annually in your area, asphalt shingles absorb water, crack, and curl; wood shakes split; concrete tiles develop stress fractures. Interlock's roofing-grade 3105-H24 / 3003-H24 aluminum alloy (ASTM B209) has zero porosity—it cannot absorb water, so ice formation inside the material is impossible. The tight four-way interlocking joints shed moisture instantly, and the Alunar 70% PVDF finish (warranted 30 years) resists the salt and mineral spray from winter roads. Your metal roof actually gets stronger in freeze-thaw climates.

Can an aluminum roof rust like steel roofing can?

Aluminum cannot rust because it contains no iron—the element that oxidizes and creates rust. Instead, aluminum naturally forms a thin oxide layer that actually protects the metal beneath; if scratched, this layer self-heals in hours or days. Steel roofs require constant protective coatings because iron oxidation is irreversible. To further guard against corrosion in wet climates like yours (835 mm annual rainfall in Kenosha County), Interlock applies its Alunar 70% PVDF fluorocarbon coating to both sides of every panel—a feature especially critical in road-salt zones. This two-sided coating carries a 30-year warranty against chalking and fading, keeping your roof functionally pristine far longer than any steel alternative.

Can metal roofing withstand Lake Shangrila Terrace wind gusts?

Yes, with confidence. The area experiences typical daily winds around 20 km/h with gusts reaching 99 km/h, and Interlock's four-way interlocking aluminum panels are warranted to resist wind speeds up to 120 mph (193 km/h) when installed to specification. The interlock geometry means each panel is mechanically fastened to its neighbors, distributing wind load across the entire roof system rather than stressing individual fasteners. This design has proven itself in coastal salt-air environments from British Columbia to Antarctic research stations since 1998. Your roof stays secure even in the occasional severe spring or autumn gust.

Will my insurance company offer discounts for a hail-resistant metal roof?

Many insurers do offer discounts for roofs rated UL 2218 Class 4—the highest impact rating available—and Interlock metal roofing qualifies. Class 4 means the roof has been impact-tested with 2-inch steel balls dropped from 20 feet, and Interlock's warranty even extends coverage to perforation from hailstones up to 1.5 inches. Contact your homeowner's insurer to ask about discounts; some carriers recognize the durability advantage in regions prone to severe weather. The combination of impact resistance and the lifetime limited warranty (non-prorated for the original owner) can lower your annual premium, offsetting part of the roofing investment. Ask your agent specifically about Class 4 metal roof credits.

Do I need to reinforce my home's structure for a metal roof?

No structural reinforcement is needed. Interlock's Mediterranean Tile profile, the heaviest at ~0.59 lb/sq ft, is about 96% lighter than concrete or clay tile, and the Shingle profile weighs just ~0.41 lb/sq ft—far less than the asphalt or wood it replaces. Because metal roofing installs at a fraction of traditional tile weight, most existing roof structures support it without modification. This light weight is a massive advantage in Wisconsin's 82 cm annual snow load: the roof itself adds almost no burden, leaving your structure's load capacity for actual snow accumulation. You can typically install over your existing roof, eliminating expensive tear-off and disposal—saving both money and landfill impact.

Can a metal roof reduce cooling costs in summer?

energy-efficient Interlock colors with thermal emissivity of 0.84 and solar reflectance up to 0.55 reflect significantly more heat than asphalt, which absorbs it. Cool Roof Rating Council certification confirms this performance. With 3,094 annual sunshine hours in your area, a reflective metal roof reduces the heat load entering your attic during warm months, lowering air-conditioning demand and extending equipment life. The benefit compounds because metal roofs don't degrade reflectivity over time like asphalt; the Alunar coating maintains its solar properties for decades (30-year warranty against fading). Even in Wisconsin's moderate summers, this translates to measurable energy savings, and the advantage grows stronger in any season with direct sunlight.

What's covered by Interlock's warranty, and for how long?

The Guardian warranty is genuinely transformative: it's a lifetime limited, non-prorated material warranty for you as the original owner—covering rust, rot, splitting, cracking, curling, and loss of impact resistance with no dollar caps or declining coverage. If you sell, the warranty transfers once to the next owner for 50 years from completion, making it a powerful resale asset. Most asphalt roofs last 15–20 years; Interlock, installed in 1998 and still performing, demonstrates three-decade real-world durability. Combined with the Alunar 70% PVDF coating warranty (30 years against fading), you're protected against the material and finish failures that plague other roofing. For a Lake Shangrila Terrace home enduring 80 freeze-thaw cycles and 835 mm of rain yearly, this warranty eliminates the replacement cycle entirely.

How much maintenance does a metal roof actually need?

Minimal—that's the appeal. Unlike asphalt shingles (which degrade, curl, and require periodic repairs), wood shakes (which split and rot, especially in Wisconsin's 80 annual freeze-thaw cycles), or clay tile (which cracks and leaks), Interlock aluminum panels don't decompose or deteriorate. You'll occasionally clear leaves from gutters and inspect flashing after severe weather, but there's no seasonal sealing, no shingle replacement, no re-staining. The Alunar 70% PVDF finish resists chalking and fading for 30 years (warranty-backed), so the roof's appearance and protective properties remain stable across 835 mm of annual rainfall. The system is CALGreen-verified for reduced maintenance, meaning your long-term labor and material costs are genuinely lower than traditional roofing.

Is metal roofing better for the environment than asphalt?

Yes, substantially. Interlock's aluminum is approximately 95% recyclable at end of life, ending the asphalt tear-off-to-landfill cycle that most roofing homeowners repeat every 15–20 years. Because aluminum panels install over existing roofs (thanks to their ~96% lighter weight compared to tile), you avoid the waste and cost of removal. Over a home's 50-year lifetime in Kenosha County, a traditional asphalt roof generates two to three full tear-offs destined for landfills; metal roofing eliminates that burden. The Alunar coating (PVDF fluorocarbon) is chemically stable and doesn't leach into soil or water. Aluminum's non-corrosive nature means no toxic runoff from rust or coating breakdown—just clean, inert recycling at the end of a roof's multi-decade life.

Is a metal roof a good choice for Lake Shangrila Terrace’s climate?

Yes. Lake Shangrila Terrace 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.
