Interlock® Aluminum Roofing — all-climates performance specs for Plymouth, 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 Plymouth
The following metal roofing FAQs are designed specifically for homeowners in Plymouth, 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 Plymouth.
Does metal roofing handle Wisconsin's heavy snow and ice buildup?
Yes—the four-way interlocking aluminum panels are engineered to shed snow and ice safely. Plymouth averages about 105 cm of snow annually, and Interlock's lightweight design (the Slate profile installs at just 0.41 lb/sq ft) prevents the structural strain that heavy snow loads place on asphalt roofs. The smooth, hard surface naturally sheds meltwater faster than compositional shingles, reducing ice dam formation. Aluminum expands and contracts uniformly, staying watertight through freeze-thaw cycles. Snow guards are available if you need additional retention for safety.
How does aluminum roofing hold up to freeze-thaw cycling?
Freeze-thaw cycling is where most roofing fails, and Plymouth experiences about 84 freeze-thaw days per year. Aluminum's oxide layer prevents the structural cracking that weakens asphalt, wood, or concrete tile. Unlike shingles that curl and split after repeated water absorption and freezing, aluminum absorbs virtually no moisture—it simply expands and contracts as a unified metal. The Alunar coating (warranted 30 years against chalking and fading) protects both panel faces, so even scratches self-heal. This is why Interlock-installed roofs in coastal salt-air climates and Antarctic research stations show no degradation.
Can an aluminum roof rust?
No. Aluminum cannot rust because it contains no iron—rusting requires iron oxidation. Instead, aluminum forms a thin, invisible oxide layer that actually protects the metal beneath and self-heals when scratched. This is why Interlock uses roofing-grade 3105-H24 and 3003-H24 aluminum alloy (ASTM B209 certified), not steel. The Alunar 70% PVDF fluorocarbon coating (applied to both sides) adds a second barrier, especially valuable in Sheboygan County's 726 mm annual rainfall. Over a 50-year lifespan, you'll never see rust stains, pitting, or corrosion that plague uncoated steel alternatives.
Will a metal roof blow off in Wisconsin wind gusts?
No. Interlock's four-way interlocking panels are warranted to resist wind speeds up to 120 mph when installed to specification. Plymouth's typical gusts reach about 101 km/h, well below that threshold. The interlocking design—where each panel mechanically locks to its neighbors on all four edges—distributes wind load across the entire roof system rather than relying on fasteners alone. The panels cannot separate or lift. This locking mechanism also means no fasteners are exposed to weather, eliminating the most common failure point in metal roofing installations.
Does a metal roof qualify for hail-damage insurance discounts?
Yes, Interlock roofing qualifies for hail discounts in many insurance programs. The panels carry a UL 2218 Class 4 impact rating—the highest available—and the Guardian Warranty covers perforation from hailstones up to 1.5 inches. In severe hail events common to the Upper Midwest, aluminum's hardness and flexibility absorb impact without cracking like asphalt, wood, or tile. Your insurer recognizes this durability; many offer reduced premiums for Class 4-rated roofs. Document your UL rating and warranty with your agent to explore available discounts.
Is aluminum roofing light enough to install over my existing roof?
Yes, and this is one of aluminum's biggest structural advantages. The Interlock Slate profile weighs just 0.41 lb/sq ft, the Shake 0.58 lb/sq ft, and the Mediterranean Tile 0.59 lb/sq ft—about 96% lighter than concrete or clay tile. Most existing roof structures can support this weight without reinforcement, saving tens of thousands in structural work. You can install directly over asphalt shingles, eliminating costly tear-off and disposal. Plymouth receives about 105 cm of snow yearly; aluminum's light weight combined with your existing roof's structural capacity handles this load far better than adding heavy tile or stone alternatives.
Do metal roofing's reflective coatings actually lower cooling costs?
Yes, Interlock's energy-efficient colors reduce cooling load by reflecting heat rather than absorbing it like asphalt. Select colors (such as Aged Copper Penny) achieve initial solar reflectance up to 0.55 and thermal emissivity of 0.84, meeting Cool Roof Rating Council standards. In summer, this reflection reduces roof surface temperature by 20–40°F compared to dark asphalt. Plymouth receives about 3113 annual sunshine hours; over a typical cooling season, this translates to measurable energy savings, especially if your attic lacks optimal insulation. Metal's reflectivity also reduces heat stress on roofing materials, extending life and protecting your home's interior.
How much maintenance does a metal roof actually require?
Far less than asphalt, wood shakes, or tile. Aluminum requires no patching, no seasonal re-sealing, no algae treatment, and no individual panel replacement. Rain naturally cleans the Alunar finish. Plymouth's 726 mm annual rainfall provides this natural rinsing, so you'll typically only need a visual inspection every 2–3 years and perhaps gutter cleaning. Unlike asphalt shingles that deteriorate and require replacement within 15–20 years, Interlock's coating is warranted 30 years against chalking and fading, and the underlying aluminum never rots, splits, or curls. This simplicity is why CALGreen verification recognizes the material for reduced maintenance.
What does Interlock's lifetime warranty actually cover, and how long does it last?
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—essentially every degradation mode. If you sell, the warranty transfers once and remains valid for 50 years from completion, making it a compelling selling point. This 50-year transferable term far exceeds asphalt's 15–20 year life. Combined with the Alunar coating's 30-year fade/chalk warranty and aluminum's inherent resistance to freeze-thaw damage (critical in Plymouth's 84 annual freeze-thaw cycles), you're protected across every failure mechanism. This is the only roof most homeowners will ever need to install.
What's the installation timeline for metal roofing in Wisconsin?
Interlock installations typically complete in 1–3 days depending on roof size and weather. Unlike asphalt replacement, which requires tear-off (adding days and disposal costs), metal panels install directly over your existing roof in most cases. Installers fasten panels to the existing substrate and seal the system; the four-way interlocking takes the structural load, not individual fasteners. Weather matters—wind gusts above about 25 km/h or active precipitation may cause delays, but Plymouth's typical winds around 20 km/h support work schedules. The speed means less disruption, faster protection, and the ability to avoid seasonal weather windows. Interlock has served this region since 2001 and coordinates around local climate patterns.
Is a metal roof a good choice for Plymouth’s climate?
Yes. Plymouth averages about 105 cm of snow, 726 mm of rain, roughly 84 freeze–thaw days a year, with peak wind gusts near 101 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.
