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

Interlock metal panels shed snow reliably because aluminum's smooth surface and four-way interlocking design prevent ice dams from forming—a critical advantage in a climate that averages about 88 cm of snow annually. The panels are rated for full snow load per ICC-ES ESR-1790 (reissued 2025), and the lightweight design means no structural reinforcement is needed. With roughly 79 freeze-thaw cycles per year in Milwaukee County, aluminum's oxide coating self-heals from minor stress cracks, while traditional asphalt becomes brittle and fails in repeated freeze cycles.

Freeze-thaw damage occurs when water penetrates materials and expands as it freezes, but aluminum's non-porous structure prevents water absorption entirely. With approximately 79 freeze-thaw days per year in your area, this immunity matters. Traditional asphalt and composite shingles absorb moisture, expand, contract, and eventually crack or curl. Interlock's roofing-grade 3105-H24 / 3003-H24 aluminum alloy (ASTM B209) has no internal voids to trap water—the Alunar® 70% PVDF coating bonds to both panel faces, sealing edges and fasteners against infiltration.

Aluminum cannot rust because it contains no iron; instead, it develops a microscopically thin, self-healing oxide layer the moment it's exposed to air. This is chemically permanent. Steel roofing, by contrast, rusts continuously once the coating is breached—a real risk over 822 mm of annual rainfall in Tippecanoe. Even in salt-air environments (coastal British Columbia, Antarctic research stations), Interlock's Alunar® 70% PVDF fluorocarbon finish—applied to both sides—provides a 30-year warranty against corrosion. Your home will never need rust repairs.

Interlock achieves UL 2218 Class 4, the highest hail impact rating available—the warranty even covers perforation from hailstones up to 1.5 inches. This rating often qualifies homeowners for insurance discounts; contact your carrier with the UL 2218 certification. Midwest storms bring impact hazards, and aluminum's dent resistance (it deforms but rarely cracks or loses structural integrity) outperforms brittle asphalt and tile. Many insurers recognize metal roofing as lower-risk, reducing annual premiums over the roof's lifetime.

Yes. Interlock's four-way interlocking system is warranted to resist wind speeds up to 120 mph (193 km/h) when installed to specification—far exceeding typical gusts in Milwaukee County, which average about 22 km/h with occasional peaks near 96 km/h. The interlocking geometry distributes wind load across multiple panels rather than relying on fasteners alone. This design has proven in coastal and mountain environments where wind shear is constant and severe. Your roof stays intact through storms that would lift or separate traditional shingles.

Interlock's aluminum panels weigh only about 0.41 lb/sq ft for the Shingle profile and 0.59 lb/sq ft for Tile—roughly 96% lighter than concrete or clay tile. This means Interlock installs directly over most existing roofs without structural reinforcement, saving thousands in framing upgrades. Traditional tile and slate require expensive foundation work; asphalt is heavier than you'd expect and degrades, eventually requiring costly tearoff and disposal. Interlock's weight advantage makes retrofits feasible for older homes, reducing labor cost and construction time.

Yes. Interlock's energy-efficient colors have initial solar reflectance up to 0.55 and thermal emissivity of 0.84—both rated by the Cool Roof Rating Council. These finishes reflect solar heat that asphalt absorbs and re-radiates into your home. With about 3,128 hours of sunshine annually in Tippecanoe, this reflectance reduces cooling load significantly. The difference compounds: asphalt reaches 160–180°F in summer and transfers that heat through the deck; Interlock stays 20–30°F cooler. Lower air-conditioning use translates to measurable savings over a 50+ year lifespan.

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 one-time transferable to the next owner for 50 years from completion. This is extraordinary in the roofing market: most asphalt and even traditional metal warranties are prorated (declining each year) and don't transfer. The transferability adds resale appeal and reflects Interlock's confidence in its roofing-grade aluminum alloy (ASTM B209) and Alunar® 70% PVDF coating.

Interlock requires virtually no maintenance—no stripping, no moss treatment, no seasonal inspection for missing shingles or cracked tiles. Asphalt shingles granulate continuously, clog gutters, and fail by year 15–20 in freeze-thaw climates like Tippecanoe's. Tile is porous, absorbs 822 mm of annual rain, cracks in freeze-thaw cycling (about 79 cycles yearly), and breaks under hail. Interlock is non-porous, self-healing, and ICC-ES evaluated for reduced maintenance per CALGreen standards. A rinse after storms keeps it looking new; that's it. No tear-off costs, no replacement cycle—just a roof that outlasts three asphalt generations.

Interlock's aluminum is non-combustible and achieves Class A fire classification (the highest available). It will not ignite, spread flame, or contribute smoke—critical in wildfire or urban fire scenarios. The ICC-ES evaluation report ESR-1790 documents this compliance under the International Building Code and International Residential Code. Unlike wood shake or asphalt (both combustible), aluminum provides genuine fire protection. Some insurers recognize non-combustible roofing and offer premium reductions. This benefit grows if your area experiences any fire risk; combined with the roof's 50+ year lifespan, you're purchasing both safety and permanence.

Yes. Tippecanoe averages about 88 cm of snow, 822 mm of rain, roughly 79 freeze–thaw days a year, with peak wind gusts near 96 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.
