Metal Roofing in Old Market Place, Wisconsin — Lifetime Interlock® Aluminum Shingles Installed Locally

Interlock's four-way interlocking panels shed snow effectively because aluminum conducts heat, and the smooth, hard surface prevents ice buildup better than asphalt. Old Market Place receives about 89 cm of snow annually across roughly 84 freeze-thaw days, which creates the wet, heavy snow that causes ice dams on conventional roofs. Metal panels' light weight (the Slate profile installs at 0.41 lb/sq ft) means your existing structure handles the load without reinforcement, and the interlocked design prevents snow from penetrating seams. Optional snow guards are available if you prefer controlled release rather than full shedding.

No. Aluminum cannot rust because it contains no iron—instead, it forms a self-healing oxide layer that actually strengthens with exposure. Wisconsin's 84 annual freeze-thaw cycles accelerate corrosion in steel or galvanized roofs, but aluminum is inherently immune to that damage. The Alunar 70% PVDF coating on both panel sides provides an additional 30-year warranty against chalking and fading, protecting the surface through thousands of temperature swings. This dual protection makes aluminum the only metal roofing material that truly ignores Wisconsin's freeze-thaw stress.

Yes. Interlock's four-way interlocking aluminum panels are warranted to resist wind speeds up to 120 mph (193 km/h) when installed to specification. Old Market Place experiences typical daily-max winds around 20 km/h with gusts reaching 104 km/h—well below the warranty threshold. The interlocking design distributes wind load across adjoining panels rather than placing stress on individual fasteners, so your roof handles spring storms and occasional severe weather without compromise. This engineering is documented in the ICC-ES evaluation report ESR-1790.

Aluminum cannot rust because it contains no iron; steel does, making rust inevitable in Wisconsin's wet climate of 781 mm rain and 89 cm snow annually. When aluminum is scratched, its oxide layer automatically reforms, healing small damage. Steel requires constant maintenance coatings and inspection to prevent rust once the finish fails. The roofing-grade 3105-H24 aluminum alloy (ASTM B209) used in Interlock panels has been manufactured since 1998 and installed from coastal salt-air homes to Antarctic research stations—proving its corrosion resistance in the harshest real-world conditions. Over 30, 50, or 80 years, aluminum eliminates the rust-and-repair cycle entirely.

Metal roofing is the last roof you buy. Asphalt shingles last 15–25 years and require replacement, creating landfill waste and labor costs every generation; Interlock carries a lifetime limited, non-prorated material warranty for the original owner, transferable to the next owner for 50 years from completion. Over a 60-year span, you'll replace asphalt 2–4 times while maintaining one metal roof. Add 30-year coating warranty coverage, minimal maintenance (no moss treatment, no seasonal repairs), potential insurance discounts, and energy savings from energy-efficient colors with reflectance up to 0.55. The higher upfront cost returns itself in avoided tear-offs, labor, and compound maintenance on aging asphalt.

The Guardian is a lifetime limited, non-prorated material warranty for the original owner, covering rusting, rotting, splitting, cracking, curling, and loss of impact resistance. This means there's no diminishing coverage year-over-year—a defect in year 1 and year 30 are treated equally. The warranty is one-time transferable, giving the next owner 50 years of protection from project completion, making your roof a permanent asset that strengthens your home's resale appeal. Combined with the 30-year coating warranty on the Alunar finish and UL 2218 Class 4 impact rating, the Guardian protects against every major failure mode.

Yes, but the benefit runs year-round, not just in summer. Interlock's energy-efficient colors with thermal emissivity up to 0.84 and solar reflectance up to 0.55 (Aged Copper Penny) reflect heat that dark asphalt absorbs, reducing attic temperatures and HVAC strain during Wisconsin's roughly 3,089 annual sunshine hours. In summer, lower attic temps mean less air-conditioning load; in winter, the reflective coating minimizes heat loss to clear, cold skies—a subtle but meaningful improvement. The Cool Roof Rating Council rating ensures the values are independently verified, not marketing claims.

Aluminum is about 95% recyclable; when your Interlock roof eventually reaches end-of-life (well beyond your ownership), the panels are melted down and reused rather than landfilled. Asphalt shingles, by contrast, are replaced every 15–25 years and largely end up in landfills because the tar and fiberglass mix is difficult to recycle. Over 60 years in Old Market Place's climate, a homeowner would typically discard three to four asphalt roof loads—thousands of pounds of waste. Aluminum eliminates this cycle. The CALGreen certification recognizes Interlock's reduced-maintenance profile, further supporting lifecycle environmental value.

Yes. Interlock panels are extraordinarily light—the Slate profile installs at just 0.41 lb/sq ft, the Shake at 0.58, and the Tile at 0.59—making them about 96% lighter than real concrete or clay tile. This weight advantage means no structural reinforcement is needed, and the roof installs directly over most existing asphalt without tear-off. The installation process is faster than reroofing with asphalt, reducing labor time and on-site disruption. Our local installer, serving the region since 2001, can assess your current deck and determine the fastest installation path during a no-obligation site visit.

Minimal. Unlike asphalt, which develops moss and mold in wet climates like Old Market Place (781 mm rain, 89 cm snow annually), aluminum doesn't trap moisture or degrade. You won't need moss treatments, seasonal repairs, or regular resealing. Asphalt shingles also curl, crack, and lose granules in freeze-thaw cycles; aluminum remains rigid and dimensionally stable through all 84 of Wisconsin's annual freeze-thaw days. A simple annual gutter cleaning is sufficient. The CALGreen verification acknowledges this reduced-maintenance advantage, which also translates to lower long-term ownership costs and fewer contractor visits over 30, 50, or 80 years.

Yes. Old Market Place 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.
