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

Aluminum's smooth, hard surface naturally sheds snow and ice before they accumulate dangerously; the four-way interlocking seams prevent water infiltration even under repeated thaw cycles. Jackson averages about 105 cm of snow annually and experiences roughly 84 freeze-thaw days per year—conditions that crack and curl asphalt shingles and cause wood shake to rot. Aluminum expands and contracts minimally across temperature swings and never splits or curls, so ice dams form less readily. The lightweight profile (Slate installs at 0.41 lb/sq ft) means no structural reinforcement is needed, and snow guards can be added to any profile if desired.

Aluminum cannot rust because it contains no iron—the element that oxidizes and corrodes. Instead, aluminum forms a thin, transparent oxide layer that actually protects the metal beneath; if that layer is scratched, it self-heals naturally when exposed to air. The Alunar 70% PVDF fluorocarbon finish (warranted 30 years against chalking and fading per ASTM standards) adds a second protective barrier on both sides of every panel. In Jackson's wet climate with about 726 mm of annual rainfall, this dual-layer protection means your roof will not develop rust stains, weeping, or structural decay—a major advantage over galvanized or painted steel systems that eventually fail.

Metal roofing costs more upfront than asphalt but is genuinely the last roof you will buy—meaning the total cost per year of service is dramatically lower. A typical asphalt roof lasts 15–20 years and requires replacement; Interlock metal roofing carries a lifetime limited, non-prorated warranty for the original owner and remains serviceable for 50+ years. Over a 50-year span, you avoid multiple tear-offs, labor, landfill fees, and the disruption of reroofing. Jackson's 84 annual freeze-thaw cycles and 105 cm of snow accelerate asphalt degradation; aluminum's resistance to these stressors means fewer repairs. The 50-year transferable warranty also adds resale appeal, often recovering a significant portion of the premium at sale.

No structural reinforcement is needed because Interlock metal panels are extraordinarily light—even the Mediterranean Tile profile, which replicates heavy clay or concrete tile, installs at roughly 0.59 lb/sq ft and is about 96% lighter than the materials it mimics. Compare that to slate, which can exceed 10 lb/sq ft, or concrete tile at 15 lb/sq ft or more. This lightweight design means the four-way interlocking panels can install directly over most existing roofs, saving you thousands in tear-off and structural upgrade costs. In Jackson, where winter snow loads are real (about 105 cm annually), the light weight also reduces total loading on your home's frame during heavy snow events.

Yes—Interlock panels are warranted to resist wind speeds up to 120 mph (193 km/h) when installed to specification. The four-way interlocking seams lock each panel to its neighbors on all four sides, creating a unified, wind-resistant envelope rather than overlapping shingles that can lift. Jackson's typical wind gusts reach about 101 km/h, well within the warranty limit. During winter, when ice and snow accumulate on your roof and amplify wind loading, the mechanical interlock design prevents the panel edges from lifting or separating. This same feature also protects against the uplift forces common in spring thaw cycles, when warming air beneath melting snow can create vacuum-like pressure.

Interlock metal roofing achieves UL 2218 Class 4 impact rating—the highest available—meaning it resists impact from hailstones up to 1.5 inches without perforation. The warranty even covers perforation damage from hail within that size range. This exceptional rating reflects the hard aluminum alloy (3105-H24 / 3003-H24 per ASTM B209) and the interlocking panel design, which distributes impact force across a wider area than single-layer shingles. Many insurers recognize Class 4 impact ratings and may offer discounts on comprehensive or hail-specific coverage. In Jackson, where spring and summer severe weather is common, this protection can meaningfully offset your insurance premium over time, particularly if you file hail claims on asphalt roofing in your area's history.

Installation timeline typically ranges from a few days for a standard home to one week for larger or complex geometries—far faster than asphalt tear-off and re-shingling. One of metal roofing's biggest advantages is that the lightweight panels (Slate at 0.41 lb/sq ft, Shake at 0.58 lb/sq ft) install over most existing roofs without tear-off, provided the deck is sound and properly ventilated. This approach saves labor, eliminates landfill waste, and reduces your out-of-pocket cost. Interlock Metal Roofing has served the Jackson region since 2001 and will assess your specific roof structure during an on-site evaluation to confirm the best installation method for your home's condition.

Metal roofing requires virtually no maintenance beyond occasional gutter cleaning and inspection after severe weather. Unlike asphalt, which degrades from UV exposure and temperature cycling (a major threat in Jackson's 84 annual freeze-thaw days), aluminum's Alunar fluorocarbon coating (30-year warranty against chalking and fading) resists weathering without needing sealant reapplication. Wood shake splits, rots, and invites moss growth in damp climates; aluminum never rots and resists moss adhesion because its smooth surface sheds moisture and algae spores quickly. With about 726 mm of rain and 105 cm of snow annually, Jackson's wet winters and spring thaws would demand regular maintenance on traditional materials. Aluminum simply outlasts them with no intervention.

energy-efficient colors deliver meaningful cooling savings through high solar reflectance and thermal emissivity. The Aged Copper Penny finish, for example, achieves initial solar reflectance up to 0.55 and thermal emissivity of 0.84, reflecting heat rather than absorbing it the way dark asphalt does. This reduces attic temperature rise and lowers air-conditioning load during Jackson's warmer months. While Jackson's average temperature is cool (8.5°C mean annual) and it receives about 3113 sunshine hours per year—less than southern regions—the reflective properties still deliver measurable savings in summer and shoulder seasons. The Cool Roof Rating Council certification confirms these gains in real-world conditions, making energy-efficiency colors a sound choice if you're seeking to lower energy consumption year-round.

Aluminum is non-combustible—it cannot catch fire or spread flames—and Interlock panels achieve Class A fire classification, the highest rating available. This makes them compliant with ICC-ES evaluation report ESR-1790 (reissued 2025 for IBC/IRC) and CALGreen criteria for fire-resistant construction. In Jackson, where dense woods and seasonal wildfire risk affect some neighborhoods, a Class A fire-rated roof provides genuine protection against ember entry and flame spread. Unlike wood shake (which is combustible and often restricted in fire-prone areas) or asphalt (which ignites at lower temperatures), aluminum offers peace of mind and may qualify you for lower homeowners' insurance premiums in areas designated as fire risk zones.

Yes. Jackson averages about 105 cm of snow, 726 mm of rain, roughly 84 freeze–thaw days a year, with peak wind gusts near 101 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.
