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: 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!

Metal Roofing FAQs for Homeowners in Polonia

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

Does metal roofing handle Wisconsin snow and ice buildup?

Yes. Interlock's four-way interlocking aluminum panels shed snow efficiently because the smooth, slippery surface resists ice dam formation — critical in Polonia, where you receive about 113 cm of snow annually and experience roughly 85 freeze-thaw cycles each year. The lightweight design (Slate at 0.41 lb/sq ft) means no structural reinforcement is needed, even when snow accumulates. Snow guards are available if you want to control roof runoff in specific areas.

Will metal roofing crack or degrade through Wisconsin's freeze-thaw cycles?

Aluminum roofing is immune to freeze-thaw damage because the material doesn't absorb water or expand when frozen. With approximately 85 freeze-thaw days per year in Polonia, asphalt shingles and wood shake routinely crack and curl under these conditions. Interlock's 3105-H24 and 3003-H24 aluminum alloy maintains its integrity indefinitely; the Alunar 70% PVDF coating is warranted 30 years against chalking and fading, so the panels stay protected through every winter cycle.

Can aluminum metal roofing rust like steel roofs?

Aluminum cannot rust because it contains no iron. Instead, it develops a microscopic oxide layer that self-heals when scratched — a natural protection mechanism. Steel roofing, by contrast, corrodes from the inside out once its coating is breached. This matters in Polonia's humid climate with 764 mm of annual rainfall: aluminum roofs installed in coastal salt-air environments and Antarctic research stations prove the material's corrosion resistance. You get a durable roof without rust stains or deterioration.

How does metal roofing perform in Wisconsin wind and gusts?

Interlock's four-way interlocking panels are warranted to resist wind speeds up to 120 mph, far exceeding typical gust events in Polonia (gusts average around 99 km/h or 61 mph). The interlocking system locks each panel to its neighbors on all four sides, distributing wind load across the entire roof rather than stressing individual fasteners. This design holds up through the sustained winds and occasional severe gusts your region experiences year-round.

Does metal roofing stand up to hail, and can it reduce insurance costs?

Interlock carries a UL 2218 Class 4 impact rating — the highest available — and the warranty even covers perforation from hailstones up to 1.5 inches. Many insurance carriers recognize this durability and may offer premium discounts for homes with Class 4-rated roofs. Contact your insurer about potential savings. In Wisconsin's variable spring and summer weather, this impact resistance translates to fewer claims and peace of mind during storm season.

Can I install metal tile on my existing roof without reinforcing the structure?

Yes. Interlock's Mediterranean Tile profile weighs only about 0.59 lb/sq ft — roughly 96% lighter than concrete or clay tile — so no structural reinforcement is required. Most existing roofs can support it during installation over current shingles, saving you the cost and disruption of a tear-off. This lightweight advantage also reduces labor complexity and installation time, keeping your project on schedule regardless of weather interruptions common in Polonia's 113 cm snow season.

Do reflective metal roofs actually save energy in Wisconsin?

Yes. Interlock's energy-efficient colors achieve thermal emissivity of 0.84 and solar reflectance up to 0.55, meaning they reflect heat rather than absorb it like asphalt. Over Polonia's roughly 3,034 annual sunshine hours, this reduces cooling load in summer and decreases the temperature swing during freeze-thaw transitions in spring and fall. The Cool Roof Rating Council verification confirms measurable energy performance, translating to lower utility bills over the roof's lifetime.

How long does it take to install a metal roof, and can you install it over my old shingles?

Installation typically takes one to two weeks depending on roof complexity and weather. Interlock panels are lightweight, so crews move quickly. Most installations proceed over your existing roof — no tear-off — which means less debris, lower labor costs, and faster completion. Rain and snow are factored into scheduling; our local installer has served the region since 2001 and knows how to navigate Polonia's weather patterns to keep the timeline realistic.

What warranty does an Interlock metal roof come with?

The Guardian Warranty is a lifetime limited, non-prorated material warranty to the original owner for defects including rusting, rotting, splitting, cracking, curling, and loss of impact resistance. It's transferable once — the next owner receives 50 years of coverage from completion — a significant resale advantage. This warranty structure reflects confidence in the product's durability. Combined with Interlock's 30-year coating warranty against chalking and fading, it's the last roof you'll likely buy for your home.

Is metal roofing better for the environment than asphalt shingles?

Yes. Interlock aluminum is roughly 95% recyclable, ending the asphalt tear-off-to-landfill cycle that repeats every 15-20 years. Over a home's lifetime, you avoid multiple shingle replacements and the associated waste. The manufacturing process in Delta, BC, and decades of field performance across climates from coastal salt air to Antarctica demonstrate that aluminum roofing extends the time between replacements dramatically. Choosing metal reduces your environmental footprint per year of roof protection.

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

Yes. Polonia averages about 113 cm of snow, 764 mm of rain, roughly 85 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.
