Review: July 20, 2016Completion: June 9, 2016

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.

Review: June 17, 2017Completion: February 17, 2017

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!

Review: June 8, 2008Completion: November 30, 2007

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.

Review: July 20, 2016Completion: November 13, 2008

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!

Review: May 17, 2017Completion: August 10, 2009

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, 2017Completion: July 31, 2008

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: April 10, 2017Completion: March 17, 2015

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.

Review: April 23, 2009Completion: May 5, 2008

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.

Review: April 16, 2026Completion: 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 16, 2017Completion: September 24, 2014

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 10, 2017Completion: March 20, 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 10, 2017Completion: February 23, 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 Ashton

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

How does a metal roof handle Ashton's average 89 cm of annual snow?

Metal roofs shed snow and ice more effectively than asphalt because the smooth, hard surface prevents water from refreezing at the eaves—the core cause of ice dams. Interlock's four-way interlocking aluminum panels are warranted to resist wind gusts up to 120 mph, which easily handles Ashton's typical maximum gusts near 104 km/h even when snow load adds lateral stress. The panels' light weight (the Cedar Shingle profile installs at just 0.41 lb/sq ft) means snow never overloads your structure the way slate or concrete tile would. Optional snow guards can be installed if you prefer controlled snow release rather than full shedding.

Will a metal roof survive Ashton's freeze-thaw cycles?

Yes—aluminum is inherently immune to freeze-thaw damage because it contains no iron and cannot rust or rot. Ashton experiences about 84 freeze-thaw days per year, which destroys asphalt (allowing water penetration and expansion) and wood shakes (splitting and curling). Interlock panels are manufactured from roofing-grade 3105-H24 / 3003-H24 aluminum alloy (ASTM B209), and their Alunar 70% PVDF fluorocarbon coating is applied to both sides, protecting against the moisture cycling that degrades traditional materials. After 25+ years of installations from coastal salt-air climates to Antarctic research stations, this design has proven durable in extreme wet-cold environments.

Can a metal roof rust, and does Wisconsin weather make that a risk?

Aluminum cannot rust because it contains no iron—the element that oxidizes and corrodes. Ashton receives about 781 mm of rain annually, creating persistent moisture conditions that would cause steel roofing to rust within years, but Interlock's aluminum develops a self-healing oxide layer that actually protects the metal underneath. Even if the coating is scratched, the aluminum's natural chemistry repairs the exposed surface. The Alunar 70% PVDF fluorocarbon finish applied to both panel sides adds 30 years of warranty coverage against chalking and fading, but the core material remains corrosion-proof regardless of rain, snow, or freeze cycles.

What's the real lifespan of an Interlock metal roof, and what does the warranty actually cover?

Interlock offers a lifetime limited, non-prorated material warranty for the original owner—the only roof warranty that doesn't diminish over time. It covers rusting, rotting, splitting, cracking, curling, and loss of impact resistance. The warranty is one-time transferable to the next owner, providing 50 years of coverage from completion, which protects your home's resale appeal. The coating itself carries a 30-year warranty against fading and chalking (measured by ASTM D4214 / D2244 standards). With Ashton's 84 annual freeze-thaw days putting stress on traditional roofs, a non-prorated lifetime warranty means your investment is protected against the exact failure modes that plague asphalt and wood in this climate.

How does an Interlock metal roof perform in hail, and could it lower my insurance?

Interlock panels carry 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 rating means the panels can withstand repeated impacts from 2-inch steel balls dropped from 20 feet, simulating severe hail. Many insurers offer discounts on premiums for Class 4-rated roofs because claims are rare. Wisconsin hail events can be intense, and while Ashton's climate data doesn't highlight hail as routine, the impact resistance becomes valuable insurance against sudden damage—plus it eliminates the risk of punctures that would allow water infiltration during the 89 cm of snow melt each spring.

Will a metal roof stay put in Ashton's windstorms?

Interlock panels are warranted to resist sustained wind speeds up to 120 mph (193 km/h) when installed to specification, which far exceeds Ashton's recorded maximum gusts near 104 km/h. The four-way interlocking design means each panel locks to its neighbors on all sides—the wind doesn't catch a loose edge. This engineering is verified under ICC-ES evaluation report ESR-1790 (the current IBC/IRC standard, reissued in 2025). Unlike asphalt shingles, which can lift and tear from wind, or standing-seam steel, which relies on exposed fasteners, Interlock's mechanical interlock distributes wind load across the entire roof plane, protecting against Wisconsin's spring and fall gust patterns.

Is a metal roof light enough to install over my existing roof without structural work?

Yes—Interlock's aluminum is extraordinarily light. The Mediterranean Tile profile, for example, weighs about 0.59 lb/sq ft, making it roughly 96% lighter than concrete or clay tile. This weight advantage means most homes can support a new Interlock roof directly over an existing asphalt roof without structural reinforcement, saving thousands in framing upgrades. Ashton experiences about 120 cm of snow annually, but because Interlock is so light, the snow load stress on your frame actually decreases compared to the original roof. Compare that to slate or genuine tile, which require engineering consultation and sometimes steel support beams. Interlock delivers architectural beauty with minimal structural demand.

How much maintenance does a metal roof need compared to asphalt or wood?

Interlock metal roofs require virtually no maintenance—no granule replacement, no moss treatment, no wood sealing. Asphalt shingles degrade under Ashton's 781 mm annual rainfall and 84 freeze-thaw days, demanding gutter cleaning and frequent inspections. Wood shakes split and curl from freeze-thaw cycling and must be chemically treated to prevent rot. Interlock's aluminum and fluorocarbon coating are inert; rain washes them clean. The CALGreen standard has verified Interlock for reduced maintenance requirements. Over a 50-year lifespan, asphalt requires re-roofing twice; wood requires constant care; Interlock requires occasional gutter cleaning and a hose-down if debris accumulates. No repairs, no recoating—just a roof that works.

What's the timeline for installing an Interlock metal roof in Ashton?

Most residential installations complete in 2–4 days depending on roof complexity and weather. Because Interlock panels are lightweight and four-way interlocking, installation is faster than slate, tile, or standing seam. You can install directly over your existing asphalt roof without tear-off, which saves days and eliminates disposal costs—critical in Ashton's freeze-thaw climate where old asphalt often has ice or moisture trapped underneath. The local Interlock installer has served the region since 2001 and knows Wisconsin weather windows well: spring (after snow melt) and fall (before freeze cycles) are ideal, though installation happens year-round. The installer can discuss your specific timeline and seasonal considerations when you request a site visit.

Is a metal roof more environmentally responsible than asphalt?

Interlock aluminum is approximately 95% recyclable, ending the asphalt tear-off-to-landfill cycle that generates millions of tons of waste annually. When your roof eventually reaches end-of-life, the panels are returned to aluminum mills and become new products—automotive parts, beverage cans, building components. Asphalt shingles are landfilled for decades because they're difficult to recycle. With Ashton's heavy rainfall (781 mm per year) and seasonal snowmelt, water infiltration into landfilled asphalt leaches binders and oils into soil. Interlock's non-combustible aluminum (Class A fire rating available) and durable coating mean one installation lasts your lifetime and into the next owner's—eliminating the environmental cost of repeated replacements. Manufactured since 1998 in Delta, BC, and installed globally, the material's low-impact profile is proven at scale.

Is a metal roof a good choice for Ashton’s climate?

Yes. Ashton 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.
