Interlock® Aluminum Roofing — all-climates performance specs for Salem, Wisconsin
| Spec / Rating | Climate / Risk Factor + What It Solves |
|---|---|
| Wind resistance: 120+ mph (193+ kph) | Extreme wind, hurricanes, storm uplift: full interlocking attachment helps prevent blow-offs, edge lifting, and panel loss in high-gust events. |
| Fire rating: Class A (with proper assembly) | Wildfire, embers, radiant heat, chimney sparks: non-combustible roof assembly provides the highest residential fire protection rating. |
| Hail resistance: UL 2218 Class 4 | Hail and impact debris: highest impact classification; resists cracking, splitting, and surface loss common with asphalt under hail strikes. |
| Snow & ice performance: interlocking, shedding profile | Heavy snow, freeze-thaw, ice dams: smooth aluminum sheds snow efficiently and the interlocking design helps block water intrusion when melt-refreeze cycles occur. (Final snow-load capacity depends on roof structure and local code.) |
| Corrosion resistance: aluminum (won’t rust) | Salt air, coastal humidity, wet climates: aluminum naturally resists rust and corrosion, reducing long-term failure risk in marine or high-moisture environments. |
| Heat / UV durability: baked-on coating system | High heat, intense sun, thermal cycling: coatings resist UV breakdown and temperature-swing fatigue, slowing fading and surface degradation. |
| Moss / algae resistance: smooth coated surface | Wet shade, organic growth: low-porosity metal surface gives moss/algae less to grip, reducing staining and maintenance. |
| Material: heavy-gauge aluminum roof profiles (Slate / Shake / Shingle / Tile / Standing Seam) | All-season structural stability: lightweight, dent-resistant metal system stays stable through large hot-cold swings and severe weather. |
| Expected lifespan: 50+ years | Long-term durability across climates: avoids re-roof cycles typical of shorter-life materials, even in high-stress environments. |
| Warranty: Lifetime-Limited, non-prorated + 50-year transferable | Lifetime protection + resale value: guarantees long-term material confidence and transfers to future owners. |

What our customers are saying:
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.
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!
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.
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!
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.
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!
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.
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.
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.
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.
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!
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 Salem
The following metal roofing FAQs are designed specifically for homeowners in Salem, 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 Salem.
Will metal roofing hold up to Wisconsin's freeze-thaw cycles?
Yes—aluminum actually thrives in freeze-thaw conditions. Salem experiences about 80 freeze-thaw days per year, and aluminum's oxide layer doesn't crack, split, or degrade when water freezes and thaws in its surface. Unlike asphalt shingles, which become brittle and fracture over repeated cycles, or wood shakes, which split from ice expansion, aluminum simply expands and contracts uniformly. The roofing-grade 3105-H24 alloy (ASTM B209) is rated to ICC-ES ESR-1790 standards for exactly these climates. Your roof won't develop stress fractures or lose its integrity season after season.
How does a metal roof handle Salem's snow load and ice dams?
Metal roofing sheds snow more effectively than asphalt because its smooth, interlocking surface provides fewer places for ice dams to form, and its superior reflectance (up to 0.55 solar reflectance on select energy-efficiency colors) means less radiant heat melts snow from below. Salem receives about 82 cm of snow annually, and the four-way interlocking panel design distributes weight evenly across your roof structure. The extraordinary lightness—Shake at 0.58 lb/sq ft—also means your framing carries less overall load. Optional snow guards can be installed if aesthetic snow slides are a concern for walkways below.
Is metal roofing safe in high winds and Wisconsin gusts?
Completely safe—Interlock's four-way interlocking aluminum panels are warranted to resist wind speeds up to 120 mph when installed to specification. Salem's typical wind gusts reach about 99 km/h (about 62 mph), well within the system's rated capacity. The interlocking design means each panel locks to its neighbors on all four sides, distributing wind load across the entire roof rather than putting stress on individual fasteners. UL 2218 Class 4 impact certification and decades of installations in coastal salt-air environments confirm that this system handles severe weather reliably.
Will my metal roof rust in Wisconsin's wet, freeze-thaw climate?
Aluminum cannot rust because it contains no iron—the element responsible for rust in steel. Instead, aluminum develops a thin, transparent oxide layer that actually protects the metal beneath. If that layer is scratched, it heals itself automatically when exposed to air. The Alunar 70% PVDF fluorocarbon finish (applied to both sides of every panel and warranted 30 years against chalking and fading) adds an extra protective barrier. With Salem's 835 mm annual rainfall and freeze-thaw exposure, you're eliminating the rust risk entirely—the roof won't degrade from moisture or salt exposure the way steel alternatives eventually do.
Does a metal roof protect against hail, and can it lower insurance costs?
Your metal roof is the most hail-resistant roofing available: UL 2218 Class 4 impact rating (the highest classification) with warranty coverage for perforation from hailstones up to 1.5 inches. This non-combustible aluminum construction also qualifies for Class A fire rating, and many insurers offer discounts for impact-resistant and fire-rated roofing. Salem's climate brings occasional severe weather, and a roof that requires no replacement after hail events—unlike asphalt shingles—can translate to tangible insurance savings over decades. Contact your insurer with the UL 2218 Class 4 rating and ICC-ES ESR-1790 documentation to discuss your specific policy.
What's the actual lifespan of an Interlock metal roof, and what does the 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. It's also one-time transferable to the next owner for 50 years from completion—a significant resale advantage. While asphalt shingles typically need replacement every 20–25 years and wood shakes every 30–40 years, aluminum roofing has installations dating back to 1998 (manufacturing began in Delta, BC) with no material degradation. In Salem's climate of about 80 freeze-thaw days yearly and moderate snow, this durability means your roof will outlast multiple replacement cycles of conventional materials.
How much maintenance does a metal roof really need?
Virtually none. Unlike asphalt shingles (which require periodic inspection, moss treatment, and debris removal), wood shakes (which split and need individual replacement), or tile (which cracks and needs resealing), aluminum roofing is CALGreen-verified for reduced maintenance. An occasional rinse during Salem's 835 mm annual rainfall keeps it clean; gutters need the same attention they would with any roof. The Alunar finish is rated to resist chalking and fading for 30 years (ASTM D4214/D2244), so color won't fade from the about 3,094 annual sunshine hours. No sealing, no spot repairs, no decay risk—just a roof that works quietly year after year.
Can I get the look of slate, shake, or tile with a metal roof?
Yes—Interlock offers five authentic profile options: Slate, Cedar Shingle, Shake, Mediterranean Tile, and Standing Seam. Each replicates the visual depth and texture of its namesake material while delivering aluminum's durability, weight savings (the Tile profile is about 96% lighter than concrete or clay tile), and maintenance freedom. You choose the look that matches your home's architecture and Salem's neighborhood character, then enjoy the performance advantages: no cracking from freeze-thaw, no rotting from moisture, and a 30-year finish warranty. These profiles are available in multiple colors, so your curb appeal doesn't require a trade-off with longevity.
Is metal roofing worth the upfront cost compared to asphalt shingles?
Over the full lifespan of your roof, metal roofing is significantly more cost-effective. Asphalt requires replacement every 20–25 years; a typical home might need 2–3 replacements over 60–75 years, including labor, tear-off disposal, and potential structural repairs. Metal roofing installed once lasts longer than the house itself, carries a lifetime limited warranty (non-prorated for the original owner), and transfers with 50 years of coverage to the next owner. Additionally, energy-efficient colors can reduce cooling costs with solar reflectance up to 0.55 and thermal emissivity of 0.84. When you total avoided replacement cycles and labor, plus energy savings and the resale value premium, a single metal roof installation becomes the last roof you'll need to buy.
Can a metal roof be installed over my existing roof, and how long does it take?
Yes—one of aluminum's key advantages is its extraordinary lightness. The Shake profile at 0.58 lb/sq ft and the Tile at 0.59 lb/sq ft (about 96% lighter than concrete or clay tile) mean no structural reinforcement is needed and installation can proceed over most existing roofs, eliminating costly tear-off and landfill disposal. The four-way interlocking panel system allows faster installation than traditional materials because each panel locks securely to its neighbors, reducing fastening points and potential weak spots. Interlock Metal Roofing has served the Kenosha County region since 2001 and can provide a detailed timeline once they assess your home's specific conditions and existing roof structure.
Is a metal roof a good choice for Salem’s climate?
Yes. Salem 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.
