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 Voltz Lake

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

How does a metal roof handle Wisconsin's heavy snow and ice buildup?

Interlock's four-way interlocking aluminum panels shed snow and ice effectively because the smooth surface resists adhesion better than asphalt shingles do. Voltz Lake receives about 82 cm of snow annually across roughly 80 freeze-thaw days per year — conditions that cause traditional asphalt to crack and curl. Aluminum's oxide layer doesn't degrade under repeated thawing, and you can add snow guards to your profile of choice (Slate, Cedar Shingle, Shake, Tile, or Standing Seam) to manage slides on steeper pitches. The lightweight design — the Shake profile weighs just 0.58 lb/sq ft — means no structural strain from accumulated snow, and the interlocking system prevents water penetration during ice-dam formation.

Will my metal roof crack or warp during Wisconsin winters?

Aluminum roofing resists the cracking and warping that plague asphalt and wood during freeze-thaw cycles because the material expands and contracts uniformly without moisture absorption. The 3105-H24 aluminum alloy (ASTM B209) used in every Interlock panel has been field-proven in Delta, BC and across North America for over 25 years. With about 80 freeze-thaw days annually in Voltz Lake and 835 mm of rain, traditional asphalt degrades faster — the freeze-thaw cycle breaks down the binder between shingle granules. Aluminum's self-healing oxide layer means even if a scratch occurs, the coating regenerates without rust. The Alunar 70% PVDF fluorocarbon finish (30-year warranty) bonds to both sides of each panel for additional protection against Wisconsin's moisture extremes.

Can an aluminum metal roof rust in Wisconsin's wet climate?

Aluminum cannot rust because it contains no iron — the element that oxidizes to create rust. Instead, aluminum develops a protective oxide layer that actually self-heals when scratched, making it ideal for regions with high rainfall like Voltz Lake (835 mm annually). This is why Interlock aluminum roofing has been installed successfully from coastal salt-air homes to an Antarctic research station since 1998. Steel roofing, by contrast, must be painted to prevent rust and often fails at cut edges and fasteners when paint fails. Because Voltz Lake's climate includes about 20 km/h average winds with gusts to 99 km/h, any cut or fastener exposure on a steel roof becomes a rust risk. Your Interlock roof needs no rust treatment, no touch-up paint, and no protective maintenance to stay corrosion-free for decades.

How safe is a metal roof in high winds or storms?

Interlock's four-way interlocking aluminum panels are warranted to resist wind speeds up to 120 mph when installed to specification — well above the typical gust speeds of 99 km/h that Voltz Lake experiences. The interlocking design means each panel locks to its neighbors on all four sides, distributing wind load across the entire roof rather than relying on fasteners alone. This has been validated by the ICC-ES evaluation report (ESR-1790, reissued 2025) for IBC/IRC code compliance. The UL 2218 Class 4 impact rating ensures the roof resists hail up to 1.5 inches — another concern during spring and fall windstorms. Because the panels are extraordinarily light (Slate profile at 0.41 lb/sq ft), wind pressure is reduced compared to heavy slate or concrete tile, and installation can proceed over your existing roof without adding weight to the structure.

Will my insurance rates drop with a metal roof rated for hail?

Your insurer may offer discounts because Interlock metal roofing carries the highest hail impact rating available: UL 2218 Class 4, which covers perforation from hailstones up to 1.5 inches. Many insurers recognize that metal roofing reduces claim frequency for weather damage — especially in regions prone to spring storms. Contact your agent with the UL 2218 Class 4 designation and the ICC-ES ESR-1790 evaluation to explore available discounts. In Voltz Lake, where you average about 3094 sunshine hours per year and typical wind gusts reach 99 km/h, hail risk varies seasonally. The Interlock Guardian Warranty covers impact-related damage, and because aluminum is non-combustible (Class A fire rating available), some insurers also recognize reduced fire-risk benefits. Document your installation with the local Interlock installer serving the region since 2001 to provide your insurer with proof of compliance and material specs.

Does a metal tile roof require expensive structural reinforcement?

No structural reinforcement is needed because Interlock's Mediterranean Tile profile weighs only 0.59 lb/sq ft — about 96% lighter than concrete or clay tile. Traditional clay tile can weigh 10–15 lb/sq ft, often requiring expensive roof frame strengthening before installation. Aluminum's exceptional light weight means Interlock installs directly over most existing roofs without adding strain to rafters, joists, or the foundation. This is one reason the ICC-ES evaluation (ESR-1790) and Intertek listing 33876 permit installation over asphalt shingles in most cases. In Voltz Lake, where annual snowfall reaches about 82 cm, a lighter roof also distributes snow load more evenly across a larger structural area. The Cedar Shingle profile installs at just 0.41 lb/sq ft. This weight advantage reduces labor costs, eliminates structural upgrades, and allows homeowners to achieve the authentic appearance of premium roofing materials without the engineering expense.

Is metal roofing worth the upfront cost compared to asphalt shingles?

Metal roofing costs more initially but becomes the last roof you buy, making it the better long-term value. Asphalt shingles typically require replacement every 15–20 years, while Interlock's Guardian Warranty is lifetime limited and non-prorated for the original owner. In Voltz Lake's climate — 835 mm rain and 82 cm snow annually, with 80 freeze-thaw cycles — asphalt deteriorates faster due to UV exposure (3094 sunshine hours yearly) and repeated temperature swings. Over 50 years, you may replace asphalt three times, including tear-off and disposal costs. Interlock aluminum never requires tear-off; the lightweight design installs over your existing roof, saving labor and landfill fees. The transferable Guardian Warranty (50 years to the next owner) also enhances resale value. Energy-efficient colors with thermal emissivity of 0.84 reduce cooling costs. While the per-square-foot cost is higher upfront, the math over the life of your home favors metal significantly — you eliminate the asphalt replacement cycle entirely.

What exactly does Interlock's lifetime warranty cover?

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 — defects that typically appear in traditional roofing within 15–25 years. Non-prorated means you pay nothing if a covered defect occurs, whether in year 5 or year 30. The warranty is transferable: the next owner receives 50 years of coverage from completion, adding substantial resale value. The Alunar 70% PVDF coating is separately warranted for 30 years against chalking and fading (ASTM D4214/D2244), ensuring color stability under Voltz Lake's 3094 annual sunshine hours. Aluminum cannot rust or rot, so those warranty terms protect against manufacturing defects or installation errors. Hail damage up to 1.5 inches is covered under the impact-resistance guarantee. This warranty structure is unique in roofing: you're not buying a roof that will need replacing in two decades; you're buying a final roof for your home and a legacy asset for the next owner.

Is metal roofing fireproof, and does that matter in Wisconsin?

Interlock aluminum roofing is non-combustible and available with a Class A fire rating — the highest fire classification available — because aluminum itself does not burn. This matters in Wisconsin because insurance carriers recognize reduced fire risk and may offer premium discounts, and many municipalities now require Class A ratings in specific zones. The non-combustible aluminum alloy (3105-H24) meets the ICC-ES evaluation (ESR-1790) and complies with IBC/IRC codes. Asphalt shingles are Class C rated at best and are combustible — a significant liability in older neighborhoods or homes near forested areas. Even in Voltz Lake's residential zones, a Class A rating strengthens your home's fire protection profile and can facilitate easier insurance approval. The combination of non-combustible material, interlocking design (no wind-driven embers enter gaps), and the CALGreen verification for reduced maintenance means a metal roof is one of the safest roofing choices available. Consult your local fire marshal about any incentives for upgrading to Class A roofing.

How much maintenance does a metal roof really need?

Interlock metal roofing requires virtually no maintenance beyond occasional visual inspection — no coating reapplication, no granule replacement, no moss treatment. The Alunar 70% PVDF fluorocarbon finish (30-year warranty) resists degradation from Voltz Lake's 835 mm annual rainfall and 3094 sunshine hours, eliminating the fading and chalking that plague asphalt and wood roofing. Traditional asphalt shingles need gutter cleaning and granule monitoring; cedar shake requires sealing every 3–5 years or it splits and rots during the region's 80 annual freeze-thaw cycles. Interlock aluminum cannot rot, split, or curl. In wet climates like Wisconsin, this non-porous surface prevents moisture absorption and mold growth — a real advantage when annual precipitation is high. The solid deck and underlayment system (installed per specification) also ensures the roof is as quiet in rain as asphalt, eliminating a common metal-roof concern. Cleaning gutters and removing debris is standard for any roof; Interlock simply doesn't require the preventive treatments that extend the life of traditional materials.

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

Yes. Voltz Lake 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.
