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 Westport

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

How does a metal roof handle Westport's heavy snow and freeze-thaw cycles?

Aluminum panels shed snow and ice far more effectively than asphalt because the smooth surface offers no grip; with Westport's typical 84 cm of annual snow and roughly 83 freeze-thaw days per year, this matters. The four-way interlocking design and solid deck installation prevent ice dams by maintaining consistent heat distribution. Unlike asphalt, which softens and refreezes with temperature swings, aluminum's oxide layer remains stable through endless freeze-thaw repetitions—it neither cracks nor curls. Snow guards are available if you prefer controlled shedding.

Why won't an aluminum roof rust like steel roofing, and does Westport's climate make a difference?

Aluminum cannot rust because it contains no iron; instead, it forms a self-healing oxide layer that actually protects the metal underneath. Westport receives about 813 mm of rain annually, yet the Alunar 70% PVDF fluorocarbon finish—applied to both sides of every panel—shields against moisture for 30 years, warranted against chalking and fading. This dual-coat strategy is especially valuable in climates with frequent wet-freeze cycles. Steel roofing, by contrast, requires constant maintenance to prevent iron oxide formation; aluminum requires none.

Is metal roofing really cheaper than asphalt over time?

Over a 50-year lifespan, Interlock metal roofing costs significantly less per year than asphalt because you install it once. Asphalt shingles last 15–20 years and then fill landfills; you'll replace yours two or three times, each time paying removal, disposal, and labor. Metal roofing's transferable lifetime limited warranty means your home's next owner inherits 50 years of coverage from completion, boosting resale appeal at no cost to you. With Westport's 813 mm annual rainfall and frequent wind gusts near 100 km/h, asphalt also degrades faster; metal's 120 mph wind rating means fewer claims and lower insurance risk.

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

No structural reinforcement is required. The Mediterranean Tile profile, for example, installs at roughly 0.59 lb/sq ft—approximately 96% lighter than genuine concrete or clay tile—so your existing roof framing handles it without modification. Even the heavier Shake profile weighs only 0.58 lb/sq ft. Most homes can accept Interlock panels directly over existing asphalt shingles, eliminating costly tear-off labor. This weight advantage matters in Westport's variable climate: lighter loads mean less stress on lumber during seasonal freeze-thaw cycles when wood expands and contracts.

Will a metal roof blow off in Westport's wind storms?

The four-way interlocking panel system is warranted to resist wind speeds up to 120 mph when installed to specification. Westport's typical wind gusts reach about 100 km/h (62 mph), well within the margin of safety. The interlocking geometry—each panel locks to its neighbors on all four sides—distributes wind load across the entire roof rather than stressing individual fasteners. This design has proven itself in coastal salt-air locations and high-altitude installations. Proper installation over solid decking is essential; have your local installer verify the substrate before beginning.

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

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 exceptional durability often qualifies homeowners for insurance discounts because claims for hail damage are rare. With Westport's roughly 3075 hours of annual sunshine and occasional severe weather, the combination of impact protection and energy-saving reflectance (some colors reach 0.55 solar reflectance) may further reduce your premiums. Check with your insurer about specific discounts for Class 4 metal roofs in your area.

Will a metal roof keep my home cooler and lower my energy bills?

energy-efficient Interlock colors reflect heat rather than absorb it, with thermal emissivity up to 0.84 and initial solar reflectance reaching 0.55 on lighter profiles like Aged Copper Penny. Over Westport's 3075 annual sunshine hours, this reflectance reduces cooling demand, especially on south and west-facing slopes. The Cool Roof Rating Council confirms measurable energy savings compared to asphalt, which absorbs solar radiation. Energy savings are modest in cooler climates but compound over decades; combined with the roof's 50-year lifespan, the cumulative benefit justifies the upfront cost for environmentally conscious homeowners.

How much maintenance does a metal roof actually need?

Interlock aluminum roofing is CALGreen-verified for reduced maintenance—you will not pressure-wash it, stain it, or seal it. Asphalt shingles require periodic inspection for granule loss and algae; wood shakes demand annual treatment to prevent rot and insect damage; real tile is fragile and leaks. Aluminum's oxide layer is self-healing, so minor scratches do not lead to corrosion. The only routine task is clearing leaves and debris from gutters and valleys, which any roof requires. Over Westport's typical year with 813 mm of rain, this drainage maintenance protects your home more effectively than on asphalt, which clogs easily.

How long does installation take, and can you install over my existing roof?

Most installations—including tear-off, solid decking, and metal panels—complete in 3 to 5 business days, depending on roof complexity and weather. Interlock Metal Roofing, serving the region since 2001, can often install directly over existing asphalt shingles, eliminating waste and labor cost. A solid deck and proper underlayment beneath the panels make the roof as quiet as asphalt in Westport's frequent rain (813 mm annually); the claim that metal roofs are loud is a myth dispelled by this construction method. Your installer will inspect the substrate and advise whether removal is necessary.

Is metal roofing actually better for the environment than asphalt?

Aluminum is approximately 95% recyclable at end of life, whereas asphalt shingles—torn off every 15 to 20 years—end up in landfills by the millions of tons annually. Over Westport's wet climate (813 mm rain, 84 cm snow), asphalt degrades faster, accelerating replacement cycles and waste. Interlock panels, manufactured since 1998 in Delta, BC, from recycled aluminum, eliminate this tear-off-to-landfill chain. At 50 years of service from one installation, a metal roof creates a fraction of the embodied carbon of three asphalt replacements. CALGreen verification confirms this environmental advantage.
