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

Yes. Aluminum expands and contracts with temperature swings, but its 3105-H24 alloy and four-way interlocking design distribute that movement without cracking or curling—problems that plague asphalt shingles through Fulton's roughly 87 freeze-thaw days per year. Asphalt becomes brittle in cold and soft in warmth; aluminum remains stable. The Alunar coating, warranted 30 years against chalking and fading per ASTM standards, also resists UV damage that worsens freeze-thaw failure in asphalt.

Fulton receives about 86 cm of snow annually, and the smooth, hard aluminum surface sheds snow and ice faster than textured asphalt, reducing ice-dam formation. Snow guards are available to prevent avalanche slides if desired. The lightweight construction—the Shake profile weighs just 0.58 lb/sq ft compared to slate or tile—means your existing roof structure carries no extra strain during heavy snow events. The four-way interlocking panels also lock panels together, so snow movement doesn't lift edges as it can with nailed shingles.

Aluminum roofing will not rust because the metal contains no iron—rust requires iron oxide. Instead, aluminum develops a microscopic oxide layer that self-heals when scratched, providing perpetual corrosion protection even in damp climates like Fulton, which averages 788 mm of rain per year. Steel roofing relies on paint coatings to prevent rust; if the coating is damaged, rust begins immediately. Interlock's aluminum is coated on both sides with Alunar 70% PVDF fluorocarbon for extra durability in wet conditions, but the metal itself is naturally rust-proof—a crucial advantage over the 20–30 year life of painted steel.

Yes. Fulton experiences typical winds around 20 km/h with gusts up to 95 km/h. Interlock's four-way interlocking aluminum panels are warranted to resist wind speeds up to 120 mph (193 km/h)—well beyond your regional storm profile. The interlocking mechanism locks each panel to its neighbors on all four sides, distributing wind load across the entire roof rather than relying on individual fasteners. Installation to spec ensures the warranty applies. This design prevents the edge-lifting and blow-off failures common in high-wind events with asphalt shingles.

No reinforcement is needed. Interlock's Mediterranean Tile profile, which visually replicates heavy concrete or clay tile, weighs only about 0.59 lb/sq ft—roughly 96% lighter than the real thing. Even the heavier Shake at 0.58 lb/sq ft is negligible compared to asphalt shingles on most existing roofs. Most homes can support Interlock metal panels as a direct overlay, eliminating costly structural work and tear-off labor. The ICC-ES evaluation report (ESR-1790) confirms installation compatibility over most existing roof decks, making upgrades affordable and faster than competitors.

Interlock requires minimal maintenance—primarily occasional cleaning and gutter upkeep. Unlike asphalt shingles, which degrade yearly and require repairs or replacement every 15–25 years, aluminum does not split, curl, crack, or lose impact resistance with age. The Alunar 70% PVDF coating is warranted 30 years against chalking and fading, so color remains stable through Fulton's roughly 3093 annual sunshine hours. Wood shakes require regular treatment and repairs; tile cracks and leaks. Aluminum simply sheds rain and snow; the Guardian Warranty covers these failure modes for the life of the original owner.

Interlock achieves UL 2218 Class 4 impact rating—the highest available—and the Guardian Warranty even covers perforation from hailstones up to 1.5 inches. Some insurers offer premium reductions for Class 4 rated roofs because they suffer minimal damage in hail events. While Wisconsin hail is moderate, the UL 2218 Class 4 rating gives you documented impact resistance that insurers recognize. Asphalt shingles typically achieve Class 1 or 2, meaning higher risk of damage and claims. This durability difference may translate to savings when you renew your homeowners policy.

Metal roofing costs more initially but is the last roof you will install. Asphalt shingles last 15–25 years; Interlock's Guardian Warranty is lifetime limited for the original owner—non-prorated—and transferable for 50 years, meaning zero replacement cost over your ownership and residual value for the next owner. Over 40–50 years, you avoid multiple asphalt replacements, tear-off disposal, and labor costs. The Alunar coating is warranted 30 years, and aluminum does not degrade like asphalt does under Fulton's 86 cm annual snow and 788 mm rain. The upfront investment typically recovers in avoided repairs and replacement cycles.

Yes. Interlock aluminum is approximately 95% recyclable at end of life, versus asphalt shingles that end up in landfills by the ton. Most asphalt roofs are replaced every 15–25 years; Interlock's lifetime warranty eliminates that tear-off-and-waste cycle over your home's ownership. Aluminum production does require energy, but the long service life means far fewer manufacturing cycles per century than asphalt. The material is also CALGreen-verified for reduced maintenance burden. Choosing Interlock means one roof installation instead of multiple asphalt installations and disposals—a meaningful reduction in construction waste and landfill contributions.

Interlock Metal Roofing serves Fulton and the surrounding Rock County region, with local installation expertise since 2001. That two-decade track record means your installer understands Wisconsin's snow load, freeze-thaw cycling, and wind patterns—conditions that shape roof design and fastening. They are familiar with local building codes, work with Fulton contractors, and stand behind the installation under the Guardian Warranty. Local service also means faster response for inspections, maintenance advice, or any questions about your roof's performance through winter storms and summer heat.

Yes. Fulton 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.
