Interlock® Aluminum Roofing — all-climates performance specs for Layton Park, 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 Layton Park
The following metal roofing FAQs are designed specifically for homeowners in Layton Park, 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 Layton Park.
Will a metal roof hold up to Wisconsin's freeze-thaw cycles?
Yes. Aluminum expands and contracts with temperature swings, but it does so uniformly—no cracking, splitting, or curling like asphalt or wood. Layton Park experiences about 79 freeze-thaw days per year, exactly the stress that degrades conventional roofing. Interlock's 3105-H24 aluminum alloy (ASTM B209) was engineered for this cycling. The four-way interlocking panels flex without fatigue, and the Alunar 70% PVDF coating stays pliable across the temperature range. Your roof will still perform at year 20 when asphalt is failing.
Can an aluminum roof rust in Wisconsin's wet climate?
Aluminum cannot rust because it contains no iron. What forms instead is a thin, invisible aluminum oxide layer that actually protects the metal underneath. When scratched, that oxide layer self-heals. Layton Park receives about 822 mm of rain annually, and the Alunar 70% PVDF fluorocarbon finish (applied to both sides of every panel) adds a 30-year coating warranty against corrosion. Even in harsh salt-air or high-moisture zones, Interlock panels installed since 1998 show zero rust. Steel roofs corrode. Aluminum roofs don't.
How does a metal roof handle Layton Park's snow and ice buildup?
Metal roofs shed snow faster than asphalt because their smooth, hard surface offers no grip. With about 88 cm of annual snowfall and typical winter wind gusts to 96 km/h, snow often slides off naturally or with minimal effort. The four-way interlocking seams are sealed and engineered to prevent ice dams—water trapped under snow cannot penetrate the panel junctions or work its way into your structure. Optional snow guards can be installed if you need controlled shedding. The lightweight aluminum (Shake profile at 0.58 lb/sq ft) means no structural concerns even with full snow load.
Is a metal roof secure against Wisconsin wind and gusts?
Yes. Interlock metal roofing is warranted to resist wind speeds up to 120 mph (193 km/h) when installed to specification. Layton Park's typical gusts reach 96 km/h—well within that margin. The four-way interlocking system locks each panel to its neighbors in all directions, so wind pressure cannot lift or separate them. The design has been validated in the ICC-ES evaluation report ESR-1790 (2025) against IBC/IRC wind loading standards. Your roof won't flap, rattle, or lift during spring storms.
Will hail damage a metal roof, and can it lower my insurance?
Interlock metal roofing carries a UL 2218 Class 4 impact rating—the highest available—and the warranty covers perforation from hailstones up to 1.5 inches. That rating often qualifies homeowners for insurance premium reductions because metal roofing is demonstrably impact-resistant. Many carriers recognize Class 4 aluminum as a superior choice. Even if hail occurs, the hard aluminum surface typically shows no penetration where asphalt or wood would fail. Contact your insurer with the UL 2218 rating; savings can offset part of your roof investment.
Do I need to reinforce my house for a metal roof?
No. Interlock's Mediterranean Tile profile installs at about 0.59 lb/sq ft—roughly 96% lighter than concrete or clay tile. Even the heavier Shake profile weighs only 0.58 lb/sq ft. This extreme lightness means no structural reinforcement is required, and Interlock can install directly over most existing roofs, saving you the cost and disruption of a tear-off. Your home's framing, already built to support asphalt shingles (which are similarly light), handles aluminum roofing without modification. The ICC-ES evaluation ESR-1790 confirms this.
What's the warranty on an Interlock metal roof, and how long will it actually last?
The Guardian warranty is a lifetime limited, non-prorated material warranty for the original homeowner, covering rust, rot, split, crack, curl, and loss of impact resistance. That means no fine print about coverage declining over time. The warranty also transfers once—the next owner receives 50 years from completion. Combined with Interlock's track record since 1998 and installations from coastal salt-air to Antarctica, you're buying a roof that will outlast the mortgage. Asphalt shingles last 15–20 years; this is your last roof.
What roof styles does Interlock offer, and do they really look authentic?
Interlock offers five profiles: Slate, Cedar Shingle, Shake, Standing Seam, and Mediterranean Tile. Each is hand-sculpted to replicate the texture, depth, and shadow lines of its namesake material—down to the individual shake splits or tile curves. They're aluminum, not paint pretending to be something else. The profiles are available in multiple colors and finishes. Whether you prefer traditional shake for a colonial cottage or standing seam for modern architecture, the look integrates seamlessly with Layton Park's residential character. You get authentic appearance with 30-year coating durability (Alunar 70% PVDF, ASTM D4214/D2244).
Is a metal roof worth the upfront cost versus asphalt shingles?
Over a 40-year horizon, Interlock is typically cheaper. Asphalt lasts 15–20 years and requires replacement twice; each tear-off costs labor and landfill fees. Interlock lasts a lifetime with zero maintenance and is 95% recyclable at end-of-life. Factoring in avoided replacements, energy savings (energy-efficiency colors reduce cooling load), potential insurance discounts (UL 2218 Class 4), and the transferable 50-year warranty boost to resale value, the total cost of ownership favors metal. Layton Park's 79 annual freeze-thaw days also accelerate asphalt failure, shortening its effective lifespan. One roof, paid once, is worth the initial investment.
Does Interlock have local installers in Layton Park?
Yes. Interlock Metal Roofing has served the region since 2001 and is the authorized local installer. That means you work with a team familiar with Milwaukee County climate patterns—the 822 mm annual rainfall, 88 cm of snow, and 79 freeze-thaw cycles that stress roofing systems. Local installation also reduces logistics, ensures rapid response to questions or concerns, and guarantees that your roof meets ICC-ES ESR-1790 specifications and local building code. Your warranty support is backed by an installer with two decades of regional experience.
Is a metal roof a good choice for Layton Park’s climate?
Yes. Layton Park averages about 88 cm of snow, 822 mm of rain, roughly 79 freeze–thaw days a year, with peak wind gusts near 96 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.
