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

Interlock's four-way interlocking panels shed snow and ice safely without accumulation, a critical advantage in a region that averages about 88 cm of snow annually. The aluminum construction is so light—the Shake profile weighs only 0.58 lb/sq ft—that structural reinforcement is never required, even under Wisconsin's typical 79 freeze-thaw cycles per year. The smooth panel surface resists ice-dam formation far better than asphalt, and optional snow guards can be installed where roof lines meet valleys, keeping snow from sliding onto walkways during thaw cycles.

Aluminum has no iron and cannot rust, so it thrives through Brookfield's roughly 79 annual freeze-thaw days without degradation. Its oxide layer self-heals when scratched, meaning the micro-damage that cracks asphalt and wood shingles simply doesn't degrade aluminum. The Alunar 70% PVDF coating—warranted 30 years against chalking and fading per ASTM standards—locks in protection across repeated temperature swings, while the four-way interlocking panels flex slightly with thermal movement rather than splitting like slate or concrete tile would.

Yes—Interlock panels are warranted to resist wind speeds up to 120 mph when installed to specification, well above Brookfield's typical wind gusts around 96 km/h. The four-way interlocking design locks each panel to its neighbors, distributing lateral forces across the entire roof assembly rather than concentrating stress on fasteners. In a region where gusts regularly exceed 20 km/h, this redundancy eliminates the nail-pull failures common on traditional shingles, and the warranty covers performance even during the severe wind events that accompany Waukesha County's spring storms.

Interlock metal roofing carries a UL 2218 Class 4 impact rating—the highest available—and the Guardian Warranty even covers perforation from hailstones up to 1.5 inches. This exceptional durability often qualifies homeowners for insurance discounts, since aluminum panels simply don't develop the leaks that hail creates in asphalt or wood. In Brookfield, where spring hail can accompany afternoon storms, Class 4 performance means you retain the roof's integrity across multiple impact events rather than filing claims for progressive damage that compounds year after year.

Interlock uses roofing-grade 3105-H24 and 3003-H24 aluminum alloy, which contains no iron and therefore cannot rust—a fundamental material advantage over steel roofing. Brookfield receives about 822 mm of rainfall annually, so corrosion resistance matters. The Alunar 70% PVDF fluorocarbon finish is applied to both sides of every panel, providing dual-sided protection in regions where freeze-thaw cycles trap moisture. Even if the coating is scratched, the aluminum's self-healing oxide layer re-forms, preventing the rust bloom and eventual perforation that degrades ferrous metals year after year.

No. Interlock's lightest profile, the Shingle, installs at just 0.41 lb/sq ft, and even the heaviest—the Mediterranean Tile at 0.59 lb/sq ft—is approximately 96% lighter than concrete or clay tile. Brookfield homes built for asphalt shingles (typically 2–3 lb/sq ft) can upgrade to the authentic look of slate, shake, or tile without any structural work. This light weight also means Interlock can install directly over your existing roof in most cases, eliminating costly tear-off labor and avoiding the landfill waste that asphalt removal creates.

Over the roof's life, metal roofing is the last roof you buy. An asphalt shingle roof typically lasts 15–20 years in Wisconsin's freeze-thaw environment and requires tear-off and replacement, while the Guardian Warranty provides lifetime limited, non-prorated material coverage to the original owner and transfers 50 years of protection to the next. In Brookfield, where you'll experience roughly 79 freeze-thaw cycles annually, asphalt's incremental failures (cupping, cracking, granule loss) require ongoing maintenance and eventual replacement, whereas aluminum's self-healing oxide layer and stable Alunar finish eliminate that cycle entirely. One roof, one invoice.

Interlock's Guardian Warranty is lifetime limited, non-prorated material coverage for the original owner, covering rusting, rotting, splitting, cracking, curling, and loss of impact resistance. The transferable provision grants the next owner 50 years from completion—a rare benefit that protects your home's resale value. Since Interlock has been manufacturing since 1998 and the company has installed roofing from coastal homes to Antarctica, the warranty reflects real-world durability across 25+ years of field performance. In Brookfield's demanding climate of freeze-thaw stress and freeze-thaw days (roughly 79 per year), that non-prorated guarantee—meaning no depreciation schedule—provides certainty that asphalt's pro-rated 20-year warranty cannot match.

Interlock requires virtually no maintenance. Unlike asphalt, which sheds granules and requires periodic inspections and spot repairs, or wood shake, which splits and curlsduring Brookfield's 79 annual freeze-thaw cycles, aluminum panels are inert. The Alunar coating resists chalking and fading across 30 years (ASTM D4214/D2244), so you won't need to re-seal or refinish. Debris clears naturally with rain (Brookfield averages about 822 mm annually), and the four-way interlocking design prevents water penetration at seams. CALGreen verified for reduced maintenance, Interlock is a true fit-and-forget system, unlike tile roofs that require seasonal cleaning and gutter maintenance due to water weight and shedding.

energy-efficient Interlock colors have thermal emissivity of 0.84 and initial solar reflectance up to 0.55, meaning they reflect heat that dark asphalt absorbs and converts to indoor warmth. Brookfield receives about 3,128 sunshine hours per year, so summer heat gain is cumulative. Cool Roof Rating Council certification confirms that reflective profiles like Aged Copper Penny outperform standard asphalt shingles in hot months, reducing AC runtime. On the flip side, in winter, the lightweight profile means no structural energy cost, and the aluminum's thermal stability resists the expansion and contraction stress that damages asphalt across Wisconsin's freeze-thaw days. One coating strategy spans the entire year.

Yes. Brookfield 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.
