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

Yes—aluminum's oxide layer self-heals when scratched, so it won't degrade from Salem Lakes' approximately 80 freeze-thaw days per year. Unlike asphalt, which becomes brittle in freeze cycles and cracks as it thaws, aluminum flexes without permanent damage. The Alunar 70% PVDF coating is warranted 30 years against chalking and fading, even through repeated temperature swings. Asphalt typically fails in 15–20 years under the same stress.

Metal panels are extraordinarily light—the Slate profile installs at just 0.41 lb/sq ft—so they handle your region's average 82 cm of annual snow without requiring structural reinforcement. The four-way interlocking design sheds snow evenly and resists ice damming better than asphalt because metal conducts and releases heat more efficiently across the entire roof surface. Snow guards are optional and install easily if you prefer controlled snow release near walkways.

The warranty covers wind speeds up to 120 mph when installed to specification. Salem Lakes experiences typical gusts around 99 km/h (61 mph), well within safe operating range. The four-way interlocking aluminum panels lock together so tightly that individual sections cannot lift independently during storms. This design, combined with ESR-1790 code compliance, gives you protection that exceeds what most asphalt or tile roofs can handle in the region.

No. Aluminum contains no iron and cannot rust. When scratched, the aluminum oxide layer self-heals automatically—a property steel roofing lacks entirely. The Alunar 70% PVDF fluorocarbon coating is applied to both sides of every panel, doubling protection in Kenosha County's wet climate (approximately 835 mm of rain annually). This dual-side finish was originally developed for coastal salt-air homes and has been proven since 1998 at an Antarctic research station, making it overqualified for Wisconsin weather.

Interlock Metal Roofing carries a UL 2218 Class 4 impact rating—the highest available—and the Guardian Warranty covers perforation from hailstones up to 1.5 inches. This rating often qualifies homeowners for insurance discounts that offset the roof's cost over time. Asphalt and wood shake roofs typically achieve only Class 1 or 2 ratings, requiring replacement after even moderate hail events. Your insurer may credit the superior impact resistance, reducing premiums for the life of the roof.

energy-efficient colors reflect heat rather than absorb it, with initial solar reflectance up to 0.55 and thermal emissivity of 0.84—Cool Roof Rating Council verified. During Salem Lakes' approximately 3094 annual sunshine hours, this means less heat enters your attic compared to asphalt. The reflective coating works year-round: in summer it reduces air conditioning load; in winter it doesn't prevent heat retention because aluminum conducts uniformly. Energy savings typically offset 15–25% of cooling costs over the first decade.

Metal requires almost no routine maintenance. Asphalt shingles need inspection after every storm, algae treatment every 3–5 years, and gutter cleaning of granule debris. Metal roofs shed debris automatically and do not degrade from weather exposure. The Alunar 70% PVDF coating is warranted 30 years against fading—no resealing or recoating. CALGreen verification confirms reduced maintenance burden. Your only task: inspect gutters and clear leaves, the same as with any roof.

Yes, in most cases. The Slate profile weighs just 0.41 lb/sq ft, and the Tile profile is approximately 96% lighter than concrete or clay tile, so no structural reinforcement is needed. Installation over existing asphalt is possible when the deck is sound. Your local installer, Interlock Metal Roofing, has served the region since 2001 and evaluates each home's structure before recommending removal or overlay. This approach saves labor costs and eliminates the asphalt tear-off-to-landfill waste cycle.

Metal costs more initially but is the last roof you'll buy. Asphalt requires replacement every 15–20 years; metal carries a lifetime limited, non-prorated material warranty for the original owner—one-time transferable to the next owner for 50 years from completion. Over 50 years, you'll replace asphalt 2–3 times while maintaining one metal roof. Factor in avoided maintenance (no algae treatment, no granule cleanup), potential insurance discounts (UL 2218 Class 4 hail rating), and energy savings across 3094 annual sunshine hours, and the total cost of ownership favors metal substantially.

The Guardian Warranty covers the original owner for life and is non-prorated—meaning a claim at year 40 receives full replacement value, not a depreciated amount. Coverage includes rusting, rotting, splitting, cracking, curling, and loss of impact resistance. The next owner receives 50 years of protection from completion. This structure reflects aluminum's actual durability: no rust is possible, and the Alunar 70% PVDF coating is warranted 30 years, giving genuine assurance that the roof will outlast most mortgages.

Yes. Salem Lakes averages about 82 cm of snow, 835 mm of rain, roughly 80 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.
