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 Trevor

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

How does metal roofing handle the snow and ice we get in Trevor, Wisconsin?

Interlock metal roofing sheds snow and ice efficiently because the four-way interlocked aluminum panels create a smooth, slippery surface that naturally slides debris off—critical in a region averaging about 82 cm of snow per year. The panels are warranted to resist wind gusts up to 120 mph, so the heavy snow loads from our freeze-thaw cycling (roughly 80 days annually) won't compromise the structure. Snow guards can be added if you want to control slide-off, and the aluminum alloy remains flexible through repeated freezing and thawing without the cracking or splitting that affects asphalt or wood shingles.

Will freeze-thaw cycles damage an aluminum metal roof?

No—aluminum's metallurgical properties actually thrive through freeze-thaw stress. With Trevor averaging about 80 freeze-thaw days per year, roofing materials experience constant expansion and contraction. Aluminum (ASTM B209, 3105-H24 alloy) has a higher coefficient of elasticity than asphalt or wood and flexes without cracking or curling. The Alunar 70% PVDF fluorocarbon coating, warranted 30 years against fading and chalking, maintains its integrity through these cycles. Where moisture penetrates asphalt seams and freezes, causing delamination, aluminum simply expands and contracts uniformly—another reason this metal has been installed from coastal salt-air homes to Antarctic research stations.

Can aluminum roofing rust in Wisconsin's wet climate?

Aluminum cannot rust because it contains no iron—the element that oxidizes into rust. Trevor receives about 835 mm of rain annually, exposing roofing to persistent moisture, yet aluminum develops a transparent oxide layer that self-heals when scratched, sealing the surface from further corrosion. The Alunar 70% PVDF coating (applied to both sides of each panel) adds a second chemical barrier warranted 30 years against degradation. Unlike steel roofing, which requires painted coatings to survive moisture exposure, aluminum's inherent corrosion resistance means the warranty isn't dependent on coating perfection—you're protected by material science, not just paint.

Is metal roofing safe in Trevor with our wind gusts?

Yes. Interlock metal roofing is warranted to resist wind speeds up to 120 mph when installed to specification, and Trevor's typical gusts reach about 99 km/h (61 mph)—well within that safety margin. The four-way interlocking aluminum panels lock together mechanically, distributing wind loads across the entire roof system rather than relying on fasteners alone to resist uplift. The ICC-ES evaluation report ESR-1790 (reissued 2025) certifies the installation method for building code compliance in high-wind regions. Over 25 years of service in the region, the local installer has documented zero blow-offs from wind events.

Does metal roofing hold up to hail, and can it lower insurance costs?

Interlock metal roofing 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 durability often qualifies homeowners for insurance discounts because hail claims drop dramatically compared to asphalt, which can be punctured or dented by much smaller stones. With roughly 3094 sunshine hours per year in Trevor, the risk of severe hail is real but not extreme; however, a Class 4 rating means your roof survives what asphalt shingles cannot. Many insurers recognize the reduced claims history and offer 5–15% premium reductions—contact your agent with the UL 2218 rating to discuss your specific policy.

Is metal roofing worth the cost compared to asphalt shingles?

Metal roofing costs more upfront—typically 2–3 times asphalt—but over the roof's lifetime it becomes the more economical choice. Asphalt shingles last 15–20 years and require replacement (tear-off costs, landfill fees, new installation). Interlock metal carries a lifetime limited, non-prorated material warranty for the original owner, with a 50-year transferable term for the next owner, meaning you install it once and it likely outlasts your ownership. In Trevor's freeze-thaw climate (about 80 days annually), asphalt degrades faster from repeated expansion and contraction; aluminum flexes without cracking. Over 40–50 years, the single installation plus minimal maintenance costs far less than two or three asphalt replacements plus labor and disposal.

What warranty does Interlock metal roofing offer?

The Guardian Warranty provides a lifetime limited, non-prorated material warranty for the original owner—covering rusting, rotting, splitting, cracking, curling, and loss of impact resistance. This means no deductible increases over time and no exclusions for normal wear. The warranty is transferable once to the next owner, who receives 50 years of coverage from the completion date, adding significant resale value. The Alunar 70% PVDF coating is separately warranted 30 years against chalking and fading (measured per ASTM standards). With Trevor's 835 mm annual rainfall and 80 freeze-thaw days, the non-prorated structure protects you from the exact failure modes that plague asphalt and wood in this climate.

Do I need to reinforce my roof structure for metal roofing?

No structural reinforcement is required. Interlock metal panels are extraordinarily light—the Mediterranean Tile profile installs at just 0.59 lb/sq ft, making it approximately 96% lighter than concrete or clay tile and substantially lighter than asphalt shingles. This light weight means the panels can install directly over your existing roof without adding stress to framing or foundation. In contrast, traditional slate or tile requires upgraded structural support (often costing $5,000–$15,000 in labor and materials) to handle the concentrated load. Aluminum's low weight combined with ICC-ES ESR-1790 certification (2025 reissue) allows installation on nearly any existing residential roof deck in Trevor, reducing installation time and labor cost.

How much maintenance does a metal roof need?

Interlock metal roofing requires minimal maintenance—far less than asphalt, wood shake, or clay tile. The non-combustible aluminum alloy (ASTM B209, 3105-H24) doesn't split, rot, or curl like wood does during Trevor's roughly 80 freeze-thaw cycles per year. There's no tar or sealant to reapply; the Alunar 70% PVDF coating (30-year warranty) is chemically bonded and self-healing. Routine care means cleaning gutters (as with any roof) and occasionally rinsing off debris to maintain aesthetics—no power-washing or chemical treatments required. Asphalt shingles need moss removal, sealant reapplication, and regular inspection for storm damage. CALGreen verification confirms Interlock metal as a reduced-maintenance material, translating to decades of minimal upkeep in your Trevor home.

How is metal roofing installed, and can it go over my existing roof?

Installation begins with inspecting the existing deck and fastening a thin metal trim and underlayment—typically completed in one day. The lightweight panels (Shake profile ~0.58 lb/sq ft) then install over the existing roof using a fastening pattern specified in ICC-ES ESR-1790, securing to the roof deck through a solid substrate. Because the panels interlock four ways and weigh a fraction of slate or tile, no structural upgrades are necessary on most Trevor homes. The process usually takes 2–4 days for a typical residential roof. Removing your old roof adds cost and landfill fees; installing over existing material saves time and money while reducing waste. The local installer, serving the region since 2001, can assess your specific roof during a free estimate.

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

Yes. Trevor 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.
