Review: June 9, 2026 Completion: June 10, 2026

Your home is your greatest investment, sheltering you from the storms. Don’t nickel and dime yourself when choosing a roof, you get what you pay for. We chose Interlock aluminum roofing for our house,and are totally pleased with it. Aluminum doesn’t rust period. The current rage of steel roofing is a racket preying on uninformed consumers who want something for next to nothing. Steel roofs are coated to prevent rust. However, once these coatings wear off rust sets in. I have personally seen an 18 year-old steel roof with significant rusting after the coating was gone. Do yourself a favor, get an Interlock aluminum roof. Dean Landers 5 star review June 9/2026 Janesville WI

Review: April 16, 2026 Completion: 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 17, 2017

Our experience with having our Interlock roof installed was exceptional. It was installed during the hottest days of the year, and none of our neighbors could believe the installers were working so hard during the hot, muggy weather. They finished several days ahead of schedule and left the yard clean and neat, even after a complete tear-off of three layers of roofing. One day during the installation, we had a rain storm, and the installers all took shelter in their vehicles. I noticed that we had a leak in a spot that had clearly had leaks before we bought the house. When I pointed it out to the installers, they went up the ladder in the pouring rain, found the cause of the problem (which, again, was a pre-existing problem, not one due to the Interlock installation) and fixed it on the spot. The service was exceptional.

Review: May 17, 2017

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, 2017

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: May 16, 2017

First off, the installation crew was great! They worked very hard, took short breaks, and completed the job very efficiently. Greg Weber, our sales representative, told us an Interlock Roof was more energy efficient than asphalt, and one of the major things we noticed over the years is how much cooler our home office upstairs is in the summertime and warmer it is in the wintertime. It’s a dramatic difference from our old asphalt roof. We have had a few neighbors even question why we invested more in an Interlock roof than a typical asphalt roof, and we always smile and say, “Everybody complains about spending money. Do you want to complain about it once or multiple times, and do you want to be all in to have the best, or not in, and hope for the best.” Thank you, Interlock!

Review: May 16, 2017

Dear Interlock Lifetime Roofing Systems, The installation was terrific. Jessie and his crew were very nice, polite, and clean and worked together like a well-oiled machine. If I was to have work done on my home for any type of project, this is the team I would recommend and would want to work on my house. Greg Weber, my sales representative, answered all my questions, set the proper expectations, and over delivered in every aspect. We had a major rainstorm shortly after the installation, and we noticed no difference in sound at all. Our Interlock roof is the talk of the neighborhood.

Review: May 16, 2017

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 16, 2017

We have been do-it-yourselfer homeowners our whole lives. We are very handy and capable when it comes to home improvements and appreciate craftsmanship and quality. And that’s what Interlock Lifetime Roofing Systems provided us with our roof. Craftsmanship and quality. Plus, durability, beauty, and experience from a company that manufactures and certify install its own product. That is something, a company that makes its own product, that was very important to us, and no other company in our market offered that, except Interlock. Another thing that was important was we didn’t want to have to deal with rust because many steel metal roofs look good new but look old and hideous down the road because of fading and rusting. Interlock is aluminum. So, it won’t rust, and it achieves and exceeds the highest rating of hail resistance. So, it’s like we said earlier – super durable! Jessie and his crew were super and hard working. We were amazed by their work ethic. That’s something that’s becoming rare nowadays. Also, we were told by a competitor that Greg Weber and Interlock would be high-pressure. That was the furthest thing from the truth. Greg was polite, personable, and knowledgeable and helped us sift through the “lesser quality, cheaper installation, sales gimmicky and overly aggressive” competitors. He provided us with a detailed range of the competition by laying out all the variables so we could make an intelligent comparison and decision. Greg helped save us a lot of time from all the other companies in our market selling what everyone else is selling or just selling stuff and making promises they can’t keep. All the asphalt guys want you to believe that their products will last, and all the steel companies want you to believe their products won’t rust, and everybody knows… That’s Just Not True! Interlock has proven itself for over four decades. That’s Impressive. That’s why we went with them, Jessie and Greg.

Review: May 10, 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 25, 2017

We visited the booth Interlock had at the Remodelling Show at State Fair Park. We got a lot of excellent information there and left our number for a call-back. We did receive the call back promptly and got an appointment right away. The estimator showed up on time and thoroughly explained the process, the product choices and the costs. We signed up for a new metal roof that evening because the advantages were so many, and the expense over time was not much different from regular shingles. This metal roof will probably outlive us! The actual work didn’t start for about two months because the company was very busy, but removing the old layers of shingles was the first process. This was done in a day, and the waterproofing membrane went on. The roofing materials were supposed to be delivered in a couple of days, which unfortunately didn’t happen.

Instead, a heavy, rainy week intervened, and we did get water in our kitchen. It took a while to get someone to call me back and that was frustrating because it damaged our kitchen ceiling. Ultimately, though, I did get a call, and the work was expedited to the following day. The roofers did the entire installation in one day and did a great job. The roof is beautiful, and we have many people stopping and looking at the wonderful work and superior materials. I know the company will honor their promise to pay for the damage to the kitchen. Once that is done, all is well. The experience wasn’t perfect, but it was as close as mother nature and shipping glitches allowed.

Review: April 10, 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 Grasslyn Manor

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

Does metal roofing handle Wisconsin snow loads and ice dams?

Yes — Interlock's four-way interlocking aluminum panels shed snow efficiently and resist ice damming because the smooth surface and thermal properties prevent the freeze-thaw cycle that traps meltwater. Grasslyn Manor receives about 88 cm of snow annually with roughly 79 freeze-thaw days per year, making shedding ability critical. The lightweight aluminum (Slate installs at 0.41 lb/sq ft) distributes weight evenly without overloading framing, and optional snow guards can be installed where local code requires them. The coating doesn't degrade from repeated thaw cycles the way asphalt does.

How does aluminum metal roofing survive freeze-thaw cycles?

Aluminum's oxide layer self-heals when scratched and doesn't absorb moisture like asphalt or wood — two conditions that drive freeze-thaw damage. In Grasslyn Manor's 79 annual freeze-thaw days, traditional roofing materials expand and contract, cracking and curling; aluminum's 3105-H24 alloy flexes without permanent deformation. The Alunar 70% PVDF coating, warranted 30 years against chalking, provides a moisture barrier that asphalt loses within 10-15 years. The result: no ice-driven splitting, cracking, or curling over decades.

Can aluminum roofing rust?

No — aluminum cannot rust because it contains no iron. Iron oxidizes into rust; aluminum oxidizes into a protective oxide layer that actually self-heals when scratched. The roofing-grade 3105-H24 and 3003-H24 alloys (ASTM B209) have been installed from coastal salt-air homes to Antarctic research stations since 1998 without rust failure. Grasslyn Manor's 822 mm of annual rainfall and occasional winter salt spray are not corrosion risks for aluminum. The two-sided Alunar coating adds 30 additional years of chalking and fading protection — redundant protection you simply don't get with steel.

Will a metal roof blow off in Wisconsin wind?

No. Interlock panels are warranted to resist wind speeds up to 120 mph (193 km/h) when installed to specification. Grasslyn Manor experiences typical daily-max winds around 22 km/h with gusts to 96 km/h — well within that rating. The four-way interlocking design creates a unified roof plane that distributes uplift across all panels rather than exposing individual fasteners. Each panel locks to its neighbors on all four sides, which is why the system qualifies for ICC-ES evaluation ESR-1790 (2025 reissue). The warranty also covers wind-driven water infiltration when the roof is properly installed.

Does hail damage metal roofing, and can I get an insurance discount?

Interlock aluminum achieves UL 2218 Class 4 impact rating — the highest available — and the Guardian Warranty covers perforation from hailstones up to 1.5 inches. Many insurers offer discounts for Class 4-rated roofing because the loss history is superior to asphalt. The aluminum's light weight (Mediterranean Tile at 0.59 lb/sq ft) actually reduces the stress of impact versus concrete or clay tile. Submit your UL 2218 Class 4 rating and the 30-year Guardian Warranty to your agent; document any insurer discount in writing before installation so you capture the savings.

Does metal roofing reduce cooling costs in Wisconsin?

Yes — Interlock's energy-efficient colors reflect solar heat rather than absorb it. Thermal emissivity reaches 0.84 and initial solar reflectance up to 0.55 on Aged Copper Penny, which means less heat enters your attic on Grasslyn Manor's roughly 3128 annual sunshine hours. Asphalt absorbs that energy and re-radiates it downward into the home. Cool Roof Rating Council measurement proves the reflectance, reducing summer air-conditioning load. Over a 50-year roof life, the energy savings often offset the material cost versus asphalt — especially in a climate where you're cooling most of the year.

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

No. Interlock aluminum is extraordinarily light — the Mediterranean Tile profile installs at just 0.59 lb/sq ft, about 96% lighter than concrete or clay tile. Most homes can accommodate this weight without any structural reinforcement. In fact, Interlock installs over most existing asphalt roofs without removing shingles first, which saves labor and waste. Your existing framing already supports heavier snow loads; 88 cm of Grasslyn Manor snow weighs far more than the metal roof itself. A local structural engineer can confirm roof-load capacity in writing if your home has unusual framing, but reinforcement is rarely required.

How much maintenance does a metal roof need?

Virtually none — aluminum does not rot, split, curl, or require painting or sealing. Unlike asphalt, which hardens and cracks in Wisconsin's 79 annual freeze-thaw days, or wood shake, which splits and requires treatment, Interlock's Alunar-coated aluminum sheds debris, resists mold, and remains dimensionally stable. Inspect gutters annually and clear leaves; that's standard for any roof. The Guardian Warranty covers all common failure modes — rusting, rotting, splitting, cracking, curling, loss of impact resistance — for the life of the original owner. The next owner gets 50 years of coverage. No other roofing material offers maintenance-free durability at this price point.

Is metal roofing worth the upfront cost versus asphalt shingles?

Over the roof's life, yes. Asphalt typically lasts 15-20 years in Wisconsin's 822 mm annual rainfall and repeated freeze-thaw cycles; you'll replace it 2-3 times in 50 years. Interlock carries a lifetime limited Guardian Warranty for the original owner — non-prorated material coverage — plus a transferable 50-year term for the next owner. The math: two asphalt replacements plus disposal costs, tear-off labor, and increased cooling costs from poor reflectance often exceed one Interlock installation. Energy savings alone on energy-efficiency colors reduce air-conditioning load across 3128 annual sunshine hours. Resale value typically increases with a known-durable roof. Calculate total cost of ownership, not just the bid price.

How long does metal roofing installation take?

Installation typically takes 2-5 days depending on roof size and complexity. Interlock's four-way interlocking system is faster to install than standing seam because panels lock together without exposed fasteners; crews don't chase individual screw holes. You can install over your existing asphalt roof without removal, which saves a full day and keeps disposal costs low — a major advantage in Wisconsin where tear-offs generate waste and labor expense. Your local Interlock installer, serving the region since 2001, will schedule around weather. With Grasslyn Manor's 822 mm annual rainfall, spring and fall are ideal; summer offers the most consistent window. A site visit confirms the exact timeline for your home.
