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

Yes. Aluminum expands and contracts smoothly without degradation because it has no grain structure like wood or brittle matrix like concrete. Lannon experiences about 79 freeze-thaw days annually, and the four-way interlocking panels allow for natural movement while remaining watertight. Unlike asphalt shingles that crack and curl from repeated temperature swings, 3105-H24 aluminum alloy maintains its structural integrity across decades of thermal cycling. The Alunar PVDF coating won't chip or peel as temperatures fluctuate between seasons.

Aluminum cannot rust because it contains no iron. When exposed to air, a protective oxide layer forms instantly on its surface and self-heals when scratched—a process that repeats automatically. This matters in Waukesha County where you receive about 822 mm of annual rainfall and occasional winter salt spray. Steel roofing requires constant vigilance against rust staining and perforation. Interlock's roofing-grade 3105-H24 and 3003-H24 aluminum alloys, combined with a 30-year Alunar PVDF coating warranty, eliminate rust risk entirely. The Guardian Warranty explicitly covers rusting—a benefit that reflects the material's true durability.

Metal roofing sheds snow and ice effectively. Lannon averages about 88 cm of snow yearly, and the smooth, sloped Slate and Shingle profiles accelerate melt and drainage without accumulation. The four-way interlocking seams prevent water infiltration if ice dams form. Metal's light weight—Interlock's Shingle at just 0.41 lb/sq ft—means no structural stress from snow load buildup, unlike traditional slate or concrete tile. Snow guards can be added for safety if desired. The key advantage: metal won't absorb moisture or weaken under repeated freeze-thaw cycles like composite materials do over 79 freeze-thaw days per year.

No structural reinforcement is needed. Interlock's Mediterranean Tile profile, which replicates the visual weight of concrete or clay tile, weighs approximately 0.59 lb/sq ft—about 96% lighter than the real thing. Your home's framing was engineered for asphalt shingles (15-20 lb/sq ft), so aluminum panels place a fraction of that load on your structure. This lightweight advantage allows installation directly over most existing roofs, avoiding expensive tear-off costs and eliminating thousands of pounds of asphalt waste to the landfill. Even in a region with 88 cm annual snowfall, the material itself adds negligible structural demand.

Absolutely. Lannon's typical peak gusts reach about 96 km/h (60 mph), with seasonal extremes potentially higher. Interlock Metal Roofing's four-way interlocking aluminum panels are warranted to resist wind speeds up to 120 mph (193 km/h) when installed to specification. The interlocking design—where each panel grips its neighbors on all four sides—distributes wind loads evenly across the roof system rather than stressing individual fasteners. This engineering approach, verified under ICC-ES evaluation report ESR-1790, gives you confidence during spring storms and winter weather events common to Waukesha County. No uplift, no flutter, no progressive failure.

Interlock Metal Roofing achieves UL 2218 Class 4 impact rating—the highest available—and the warranty even covers perforation from hailstones up to 1.5 inches. In Waukesha County's thunderstorm climate, this non-negotiable protection matters. Unlike asphalt shingles that dimple, crack, or lose granules in severe hail, aluminum panels remain intact and watertight. Many insurers offer discounts on premiums for Class 4 rated roofs because the claims history is dramatically lower. Your agent can review Interlock's certifications and your specific policy. Over a 50-year lifespan, hail resistance alone can offset a significant portion of the material's cost difference from asphalt.

The Guardian Warranty is lifetime limited and non-prorated for the original owner, covering rusting, rotting, splitting, cracking, curling, and loss of impact resistance—conditions that plague asphalt and wood-based roofs. When you sell your home, the warranty transfers once to the next owner for a 50-year term from completion. This dual-owner protection is rare in the roofing industry and reflects Interlock's confidence in aluminum durability. Unlike asphalt shingles (15-25 year reality) or wood shakes (20-40 years with maintenance), metal roofing installed in 2024 will likely outlast your ownership and transfer value to the buyer. In Waukesha County's 79 annual freeze-thaw cycles, that longevity compounds over decades.

Metal roofing requires minimal maintenance. You'll rinse debris after fall storms and inspect gutters annually—standard for any roof. Unlike asphalt shingles, which deteriorate visibly within 10-15 years and shed granules into gutters, Interlock's aluminum panels stay structurally sound across decades. Wood shakes crack, curl, and rot within 20-40 years, especially in Wisconsin's wet climate with 822 mm annual rainfall and 79 freeze-thaw days. The Alunar PVDF coating is rated 30 years against chalking and fading (ASTM D4214/D2244), so color stability outlasts typical roof replacement cycles. No moss treatment, no repairs from freeze damage, no granule loss—just a roof that performs.

Installation typically takes 2-5 days depending on roof size and complexity. One major advantage: Interlock panels install directly over most existing asphalt roofs. You avoid a costly tear-off, eliminate disposal fees, and skip the 3-5 day delay while old material goes to the landfill. Your contractor walks the existing deck, checks for rot or structural issues, then installs a solid deck and underlayment before laying the interlocking aluminum panels. This over-roof approach is code-compliant under ICC-ES ESR-1790 and reduces labor disruption to your household. Interlock Metal Roofing has served the region since 2001, so local crews know Waukesha County conditions and installation standards inside out.

Aluminum is approximately 95% recyclable, and Interlock panels can be reclaimed and melted down at end of life with zero degradation in quality. Contrast that with asphalt shingles: 12 million tons land in U.S. landfills annually because the material cannot be recycled. In a single tear-off of an average-sized Lannon home, 3-5 tons of asphalt waste goes to a landfill forever. Aluminum's lightweight design (Shingle at 0.41 lb/sq ft) means less transportation energy and fewer truck trips. Manufactured since 1998 in Delta, BC using proven processes, Interlock roofing closes the loop: old panels become new ones. CALGreen verification confirms reduced maintenance and extended lifecycle compared to asphalt, lowering your home's environmental footprint over 50+ years.

Yes. Lannon 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.
