Metal Roofing in Medina, Wisconsin — Lifetime Interlock® Aluminum Shingles Installed Locally

Yes—aluminum's oxide layer self-heals when scratched, so freeze-thaw cycling does not degrade it the way it cracks asphalt or wood. Medina experiences roughly 87 freeze-thaw days per year and about 120 cm of snow. Aluminum expands and contracts with temperature swings, but the four-way interlocking panels absorb this movement without splitting or curling. The Alunar 70% PVDF coating is warranted 30 years against damage, and the lifetime limited warranty covers cracking and curling—conditions that plague traditional materials in your climate.

Metal roofs shed snow and ice faster than asphalt because their smooth, hard surface offers less friction. Medina receives about 120 cm of snow annually and gusts to 95 km/h. The Interlock panels' lightweight design—the Shake profile at just 0.58 lb/sq ft—means no structural reinforcement is needed, even in snow-heavy years. Snow guards are available if you prefer controlled shedding. The hard metal surface itself prevents ice dams; water that would refreeze on asphalt runs straight off.

Aluminum cannot rust because it contains no iron. When exposed to moisture—Medina averages about 790 mm of rain per year—aluminum naturally forms an oxide layer that protects the underlying metal and self-heals when scratched. Steel roofing rusts; aluminum does not. The Alunar coating is applied to both sides of every panel for extra protection in wet climates, and the lifetime limited warranty explicitly covers rusting. Your roof will not develop the brown streaks or structural decay that iron-based metals suffer.

Metal is more expensive initially but costs less over your home's life because you install it once and keep it. Asphalt lasts 15–20 years; Interlock's lifetime limited warranty covers the original owner indefinitely, with a 50-year transferable term for the next owner. In Medina's wet, freeze-thaw climate with 87 freeze-thaw cycles yearly, asphalt deteriorates faster than in mild regions. When you factor in disposal, labor, and time for multiple replacements, metal becomes the last roof you buy. The warranty is non-prorated—no degrading coverage as the roof ages.

Interlock panels are warranted to resist wind speeds up to 120 mph when installed to spec, and Medina's typical gusts reach 95 km/h (59 mph). The four-way interlocking system locks panels together on all sides, so wind cannot lift or separate them like it can asphalt shingles. The system is engineered for the IBC/IRC codes (verified in ICC-ES evaluation ESR-1790, reissued 2025). Unlike shingles that fail by peeling from the edges, Interlock's mechanical interlock distributes wind loads across the entire roof.

Many insurers do offer discounts for UL 2218 Class 4 roofing—the highest impact rating available. Interlock carries this rating and is warranted against perforation from hailstones up to 1.5 inches. Contact your agent with the UL listing number 33876 and the product's Class 4 certification. Because Wisconsin experiences hail as part of severe summer weather, and because metal roofs significantly reduce claim frequency, insurers recognize the risk reduction. Ask your agent whether you qualify for a discount; the rating often pays for itself in lower premiums over a few years.

Metal requires far less maintenance than asphalt or wood shake. Asphalt degrades in Medina's 87 annual freeze-thaw cycles and loses granules in rain and UV exposure. Wood splits and rots in your 790 mm of annual rainfall and freeze cycles. Interlock aluminum needs only occasional gutter cleaning and debris removal—no resealing, no replacement of individual shingles, no algae or moss treatment. The Alunar coating is CALGreen-verified for reduced maintenance. Gutters and flashing, not the roof itself, require your attention.

Yes. Because Interlock panels weigh as little as 0.41 lb/sq ft (the Slate profile), they install directly over most existing roofs without structural reinforcement. The lightweight design—about 96% lighter than concrete or clay tile—means no added stress on your home's framing. Installation is typically faster than tear-off, reducing labor time and debris disposal costs. Interlock Metal Roofing has served this region since 2001 and can assess your deck and advise whether overlay or tear-off is best for your home. Most Medina roofs qualify for direct installation over asphalt.

energy-efficient colors reflect solar heat instead of absorbing it like asphalt. The Aged Copper Penny finish has initial solar reflectance up to 0.55 and thermal emissivity of 0.84. Medina receives about 3,100 hours of sunshine annually; reflective coatings reduce the heat your roof transfers into the attic and living space. This lowers air-conditioning load during summer months and works year-round by preventing thermal buildup. Cool Roof Rating Council certification confirms the reflectance; the warranty ensures the coating stays effective for 30 years, protecting your energy savings long-term.

Metal roofing dramatically improves curb appeal because Interlock's five profiles—Slate, Cedar Shingle, Shake, Mediterranean Tile, and Standing Seam—replicate premium materials at a fraction of the weight and maintenance cost. Buyers recognize the durability, low upkeep, and style. The one-time transferable warranty gives the next owner a 50-year term from completion, which is a major selling point. The lightweight design (0.58 lb/sq ft for Shake) requires no costly structural upgrades, making the home more attractive to renovation-conscious buyers. Metal roofs signal a well-maintained, forward-thinking home.

Yes. Medina averages about 86 cm of snow, 788 mm of rain, roughly 87 freeze–thaw days a year, with peak wind gusts near 95 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.
