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

Metal roofing sheds snow and ice far better than asphalt because its smooth, interlocking aluminum surface creates no grip for accumulation. Forward receives about 84 cm of snow annually across ~85 freeze-thaw cycles, which can crack asphalt shingles as ice expands and contracts. Interlock's four-way interlocking aluminum panels are also extremely light—the Slate profile weighs just 0.41 lb/sq ft—so snow load never stresses your structure. You can add snow guards to your roofline if desired, but the metal itself won't trap moisture that leads to ice dams the way wood shakes and asphalt do.

No. Aluminum has no iron content—it cannot rust, and it actually strengthens under freeze-thaw stress rather than degrading. Forward endures roughly 85 freeze-thaw days per year in a climate that averages 9.4°C, which is brutal on materials that absorb water, like asphalt, wood, and concrete tile. Aluminum's oxide layer seals the metal and self-heals if scratched, so each winter cycle makes it more resilient. The Alunar 70% PVDF fluorocarbon coating, warranted 30 years against chalking, adds a second line of defense. You won't see the cracking, curling, or splitting that traditionally plague roofing materials in climates like yours.

Steel roofing corrodes and rusts because iron oxidizes into a flaky, expansive compound that destroys the material from within. Aluminum contains zero iron, so rust is physically impossible. Interlock panels are manufactured from roofing-grade 3105-H24 and 3003-H24 aluminum alloy per ASTM B209 and coated with Alunar 70% PVDF fluorocarbon on both sides—extra critical in salt-air environments and equally protective during Forward's ~780 mm of annual rain and 18 km/h average winds with gusts to 93 km/h. The oxide layer that forms on aluminum is only a few molecules thick and self-heals when scratched. The Guardian lifetime limited warranty covers rusting; corrosion simply does not occur with this material.

Yes—Interlock's four-way interlocking panels are warranted to resist wind speeds up to 120 mph (193 km/h), far above the 93 km/h gusts typical of Forward. The interlocking system means each panel locks to its neighbors on all four sides; wind cannot find an edge to peel or lift. Forward's average wind speed of about 18 km/h is well within the design envelope. Forward homeowners benefit from a roofing system engineered for coastal and mountain installations—the same panels installed on Antarctic research stations and salt-air homes. Properly installed to spec, your roof becomes one unified, aerodynamic shell.

Interlock achieves UL 2218 Class 4 impact rating—the highest available—and the Guardian warranty covers perforation from hailstones up to 1.5 inches. Class 4 rating means the roof survives repeated drops of 2-inch steel balls from 20 feet without cracking or losing impact resistance. Many Forward homeowners file fewer or smaller claims with metal roofing, which can interest insurers. Compare that to asphalt shingles, which dent and lose granules (reducing lifespan), or wood shakes, which split under impact. Some insurers offer discounts for metal roofing; call your agent with the UL 2218 Class 4 specification. The light weight (0.41 lb/sq ft for Slate) also means no structural reinforcement, keeping labor and total project cost down.

energy-efficient Interlock colors with thermal emissivity of 0.84 and solar reflectance up to 0.55 (Aged Copper Penny) reflect the sun's heat rather than absorbing it like asphalt does. Forward receives about 3,093 hours of sunshine annually, so reflectance matters. Metal roofs are rated by the Cool Roof Rating Council and can lower attic temperatures by 20–30°F on sunny days, reducing air-conditioning runtime. In winter, the same reflectance causes no penalty because your home is heated from inside. The lighter weight (Slate at 0.41 lb/sq ft versus slate tile at 12+ lb/sq ft) also means less thermal mass to cool. Choose an energy-efficiency color if energy savings are a priority, and pair it with proper attic ventilation for maximum seasonal benefit.

No. Interlock's aluminum panels are extraordinarily light—the Mediterranean Tile profile, which replicates heavy concrete or clay tile, weighs just 0.59 lb/sq ft and is about 96% lighter than the authentic material it mimics. Forward's typical residential framing handles asphalt shingles at 2–3 lb/sq ft; Interlock never exceeds that. In fact, metal roofing often installs over your existing roof, saving demolition labor and landfill costs. A structural engineer is rarely needed. The lightweight aluminum construction is one of the largest hidden cost savings: no roof trusses to upgrade, no engineer stamps, no installation delays. You get the aesthetic of slate, shake, or tile with the installation simplicity of asphalt shingles.

Installation typically takes 3–7 days for a standard residential home, depending on roof size, pitch, and complexity. Interlock Metal Roofing has served the Forward area since 2001 and coordinates around weather windows. The lightweight panels can install directly over existing asphalt, wood shake, or tile—no tear-off required unless there are two or more layers already present or structural damage underneath. That means no weeks of debris, dust, or logistical chaos. You avoid landfill costs and the environmental footprint of hauling away old roofing. The installer secures panels to the deck with corrosion-resistant fasteners and seals penetrations like vents and skylights. Most homeowners stay in their homes during the work without disruption.

The Guardian warranty is a lifetime limited, non-prorated material warranty for the original owner, covering rusting, rotting, splitting, cracking, curling, and loss of impact resistance. It's transferable once to the next owner for 50 years from completion—a significant resale bonus. The Alunar 70% PVDF fluorocarbon coating is separately warranted 30 years against chalking and fading per ASTM D4214 and D2244. Aluminum roofing routinely lasts 40–60 years in harsh climates; Forward's ~780 mm annual rainfall and 85 freeze-thaw days won't degrade it. When you retire, the roof is still in service. Compare that to asphalt (15–20 years), wood shakes (25–40 years with ongoing maintenance), or concrete tile (25–40 years but much heavier). Metal roofing is genuinely the last roof you buy.

Metal roofing requires minimal maintenance—occasional gutter cleaning and a light spray rinse to remove pollen, which is notable in Forward's 3,093 annual sunshine hours. No recoating, no replacing individual damaged sections, no moss or algae treatment, and no wood rot inspections like shake roofs demand. Asphalt shingles deteriorate under UV and thermal cycles; Forward's ~85 freeze-thaw days accelerate that damage and force repairs or full replacement every 15–20 years. Metal roofing is CALGreen-verified for reduced maintenance. The Alunar coating protects both sides of each panel (most competitors coat only one), extending service life and minimizing weathering. A metal roof installed in 2001 is still performing. An asphalt roof installed then would be in a landfill.

Yes. Forward averages about 84 cm of snow, 780 mm of rain, roughly 85 freeze–thaw days a year, with peak wind gusts near 93 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.
