Interlock® Aluminum Roofing — all-climates performance specs for Norway Grove, 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 Norway Grove
The following metal roofing FAQs are designed specifically for homeowners in Norway Grove, 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 Norway Grove.
How does a metal roof handle Wisconsin's snow and ice buildup?
Metal roofing sheds snow and ice far more efficiently than asphalt because its smooth, hard surface prevents moisture from bonding — critical in Norway Grove, where you average about 89 cm of snow annually and experience roughly 84 freeze-thaw cycles each year. The four-way interlocking aluminum panels are warranted to resist wind gusts up to 120 mph, so heavy snow loads won't shift the roof. Optional snow guards can be installed if you want to retain snow for insulation or prevent it from sliding onto walkways. Unlike asphalt, which softens and traps ice, aluminum's thermal properties mean less heat loss means less melting-and-refreezing cycles — reducing ice dam risk.
Will freeze-thaw damage affect an aluminum metal roof over time?
No — aluminum's oxide layer actually strengthens under freeze-thaw stress rather than breaking down like asphalt or wood shakes. In Norway Grove's 84 annual freeze-thaw days, this matters enormously. The 3105-H24 aluminum alloy (ASTM B209) used in Interlock panels was engineered for exactly these conditions; it expands and contracts predictably without cracking, splitting, or developing stress fractures. The Alunar 70% PVDF fluorocarbon coating is applied to both sides of every panel, shielding against moisture that accelerates freeze-thaw failure in single-coated materials. This dual-sided protection is why the coating carries a 30-year warranty against chalking and fading — it stays flexible through thousands of seasonal cycles.
Why don't aluminum roofs rust like steel ones do?
Aluminum cannot rust because it contains no iron — the element that oxidizes into rust. Instead, aluminum develops a thin, invisible oxide layer that actually protects the metal beneath and self-heals when scratched. This is why Interlock has been manufacturing roofing since 1998 and installing panels everywhere from coastal salt-air homes to an Antarctic research station without rust failure. Steel roofs, by contrast, rely on paint coatings to prevent iron oxidation; if that coating is damaged, rust spreads underneath where you can't see it. In Dane County's ~781 mm of annual rainfall and Wisconsin's road-salt environment, aluminum's corrosion immunity is a genuine structural advantage — your roof won't develop the hidden deterioration that shortens steel roofing life.
Can my existing roof framing support a metal roof, or will I need structural upgrades?
In almost all cases, no structural reinforcement is needed — that's one of aluminum's biggest advantages. The Interlock Slate profile weighs just 0.41 lb per square foot; the Shake is 0.58 lb/sq ft; the Mediterranean Tile is only 0.59 lb/sq ft, making it about 96% lighter than concrete or clay tile. Most homes built in the last 50 years were framed to handle asphalt shingles (which are heavier), so aluminum metal roofing actually reduces load on your home. You can even install it directly over your existing roof in most cases — no tear-off needed. A local installer can assess your specific framing, but the exceptional lightness of aluminum means the structural concerns that plague homeowners considering traditional tile or slate simply don't apply here.
How well does metal roofing hold up to Wisconsin wind gusts?
Metal roofing is engineered specifically for wind — Interlock's four-way interlocking aluminum panels are warranted to resist wind speeds up to 120 mph when installed to specification. Norway Grove's typical gusts reach about 104 km/h (65 mph), well within this margin. The four-way interlock means each panel is mechanically fastened to its neighbors; wind doesn't catch edges and peel shingles back like it does with asphalt. The ICC-ES evaluation report ESR-1790 (reissued 2025 for IBC/IRC compliance) confirms this performance. Asphalt shingles, by contrast, rely only on nails and adhesive — inadequate for sustained gusts. If your home is on a ridge or exposed lot, metal roofing's locked-panel system is genuinely superior to traditional materials for wind resistance.
Does a metal roof hold up to hail, and could it lower my insurance?
Yes to both. 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. Class 4 is rare; most asphalt shingles max out at Class 1 or 2. Because metal roofing demonstrates measurable impact resistance, some insurers offer premium discounts; check with your agent about potential savings. In Wisconsin's hail season, this isn't theoretical protection — it's documented performance. The aluminum's hardness means dents may occur (cosmetic only), but the structural integrity and weather tightness are unaffected. For a homeowner in Dane County, a roof that won't need replacement after a severe hail event has both insurance and peace-of-mind value.
What's the difference between a lifetime warranty on a metal roof and a regular roof warranty?
The Guardian Warranty is a lifetime limited, non-prorated material warranty for the original owner — meaning you never pay more for coverage as the roof ages. It covers rusting, rotting, splitting, cracking, curling, and loss of impact resistance. This is fundamentally different from prorated warranties that shift costs to you over time. The warranty is transferable once, giving the next owner 50 years of coverage from completion — a major selling point for resale. In Norway Grove, where freeze-thaw cycles, seasonal snow load, and wind gusts are all factors, this non-prorated coverage means you won't face a repair bill for material failure regardless of age, as long as you own the home. Most asphalt roofs last 15–20 years before major repairs; this warranty structure reflects aluminum's genuine durability difference.
How much maintenance does a metal roof really need compared to asphalt or wood?
Aluminum metal roofing requires essentially zero maintenance — no sealing, no coating reapplication, no algae or moss treatment. The Alunar 70% PVDF fluorocarbon finish is rated for 30 years against fading and chalking (energy-efficiency and Cool Roof Rating Council tested), so your roof's appearance doesn't degrade like asphalt does. Asphalt shingles require regular inspections, sealed nails, periodic resealing, and can develop algae stains in humid climates. Wood shakes demand annual maintenance, regular sealing, and replacement of individual damaged pieces. With Norway Grove's ~3,089 sunshine hours and 89 cm of snow annually, asphalt breaks down faster; metal stays stable. You may rinse your roof occasionally if debris settles, but that's optional. The CALGreen standard specifically recognizes metal roofing for reduced maintenance — saving you money and hassle over decades.
Will a metal roof actually lower my cooling costs in summer?
Yes — Interlock's energy-efficient colors have a thermal emissivity of 0.84 and initial solar reflectance up to 0.55, meaning they reflect heat that asphalt absorbs. The Aged Copper Penny finish is specifically rated by the Cool Roof Rating Council for reflectance. While Norway Grove's mean temperature is cool at 9.1°C annually, summer days still warm your attic; a reflective metal roof reduces that heat gain compared to dark asphalt. You won't see dramatic AC savings like homeowners in Arizona, but you will see measurable reduction in cooling demand and peak load — particularly on the south and west faces of your roof. Combined with metal's superior ventilation characteristics and lower thermal mass, the energy benefit compounds over a 50-year lifespan. It's one of many reasons metal roofing's total cost of ownership is lower than traditional materials.
Is a metal roof actually better for the environment than asphalt shingles?
Yes — aluminum roofing breaks the asphalt tear-off-to-landfill cycle. Interlock panels are approximately 95% recyclable; when your roof eventually reaches end-of-life (decades away), the aluminum can be melted and reused indefinitely without degradation. Asphalt shingles, by contrast, become landfill waste — roughly 20 million tons annually in North America. Tear-off labor and disposal fees are eliminated if you install metal directly over your existing roof, reducing the project's carbon footprint. The aluminum alloy (3105-H24 / 3003-H24) is sourced and manufactured with established recycling infrastructure; the Alunar fluorocarbon coating is durable enough that recoating is never needed. For a homeowner concerned about environmental impact, choosing a 50+ year roof that won't require replacement and can be fully recycled at end-of-life is one of the most concrete sustainability decisions available.
Is a metal roof a good choice for Norway Grove’s climate?
Yes. Norway Grove averages about 89 cm of snow, 781 mm of rain, roughly 84 freeze–thaw days a year, with peak wind gusts near 104 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.
