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

Yes—aluminum's oxide layer actually strengthens when exposed to repeated freeze-thaw stress, unlike asphalt or wood shingles that crack and curl. Concord experiences about 81 freeze-thaw days per year, plus roughly 88 cm of snow and 775 mm of rain, creating the exact cycling conditions where asphalt fails fastest. Interlock's 3105-H24 and 3003-H24 aluminum alloys are specifically engineered for these extremes. The coating remains flexible across temperature swings, and the four-way interlocking panels shed water and ice melt instantly, preventing the standing water that triggers freeze damage in traditional roofs.

Metal roofs shed snow faster than asphalt because their smooth surface and low friction accelerate melt and slide-off, reducing ice dam formation. Concord averages about 88 cm of snow annually with gusts reaching 100 km/h, so snow load is real—but here's why aluminum wins: the Shake profile weighs only 0.58 lb/sq ft and the Tile just 0.59 lb/sq ft, roughly 96% lighter than concrete or clay tile. Your home's existing structure handles the snow load without reinforcement. The warranty covers wind speeds up to 120 mph, so even with snow pack, interlocking panels stay locked in place during winter storms.

Aluminum physically cannot rust because it contains no iron. Instead, it forms a self-healing oxide layer that protects the metal beneath. In Concord's climate—775 mm of annual rainfall and freeze-thaw cycling that accelerates corrosion in steel—this matters enormously. Even when scratched, the oxide layer reforms automatically. The Alunar 70% PVDF fluorocarbon coating (applied to both sides of every panel) provides a 30-year warranty against chalking and fading, giving you two independent layers of protection. Steel roofs require constant maintenance to prevent rust stains and holes; aluminum eliminates that burden entirely.

The four-way interlocking design—where each panel locks top, bottom, left, and right to its neighbors—transfers wind load across the entire roof plane rather than relying on fasteners alone. Concord's typical gusts reach 100 km/h with occasional stronger storms, and the warranty covers sustained wind up to 120 mph (193 km/h), meaning your roof stays attached to your home even in severe conditions. The UL 2218 Class 4 hail rating (the highest impact classification) confirms the panels' structural rigidity. Once installed over solid decking, the interlocked assembly acts as one unified membrane—no lifting, no separation.

Interlock carries the UL 2218 Class 4 impact rating—the highest available—and the warranty even covers perforation from hailstones up to 1.5 inches. Many insurers recognize this rating and offer premium discounts on metal roofs because the claims risk is dramatically lower than asphalt. Concord's climate includes occasional severe weather, and a durable roof that resists impact loss reduces insurer liability. Contact your agent with the UL 2218 Class 4 designation to request a quote adjustment; several carriers in Wisconsin now incentivize non-combustible, impact-resistant roofing. The lifetime limited warranty protects you if any damage does occur, with no prorated deductibles for the original owner.

The Guardian Warranty is a lifetime limited, non-prorated material warranty for the original homeowner—it covers rusting, rotting, splitting, cracking, curling, and loss of impact resistance with no proration over time. If you sell your home, the warranty transfers once to the next owner for a 50-year term from completion, adding significant resale appeal. The coating itself carries a separate 30-year warranty against chalking and fading (ASTM D4214/D2244 standards). This structure—combined with aluminum's inherent resistance to corrosion in Concord's wet climate—means you're buying the last roof you'll install, eliminating the tear-off-and-replace cycle every 15–20 years that asphalt requires.

No. The Slate profile installs at just 0.41 lb/sq ft, and the Mediterranean Tile (despite its authentic appearance) weighs only 0.59 lb/sq ft—roughly 96% lighter than genuine concrete or clay tile. Most homes built to standard code can accommodate this load without any structural modification. In fact, Interlock installs directly over existing asphalt or wood roofs in most cases, since you're removing heavy material and replacing it with something feather-light. This means no costly reinforcement, no engineering reports, no delays—just straightforward installation. The ICC-ES evaluation (ESR-1790, reissued 2025) confirms code compliance and confirms that aluminum panels meet or exceed structural requirements across the entire snow-load and wind-gust range Concord experiences.

Interlock Metal Roofing has served Jefferson County and the surrounding region since 2001, meaning your installer understands Concord's specific climate challenges—heavy snow (88 cm annually), frequent freeze-thaw cycling (about 81 days per year), wind gusts to 100 km/h, and high rainfall (775 mm per year). Factory training and 20+ years of local experience translate to proper installation of interlocking panels, correct underlayment and ventilation for your climate, and confident warranty support. When you call with questions about snow guards, ice management, or maintenance, you're speaking with someone who has installed hundreds of roofs in your exact conditions and knows which profiles perform best in Jefferson County.

Yes, if you choose energy-efficient colors. Select Interlock profiles with high solar reflectance (up to 0.55 in Aged Copper Penny) and thermal emissivity of 0.84 reflect incoming heat rather than absorbing it like asphalt does. On Concord's 3,074 sunshine hours per year, this reflectivity compounds month after month. The Cool Roof Rating Council confirms the performance difference: reflective metal roofs stay cooler in summer, reducing the cooling load on your air conditioner and lowering energy bills. Aluminum's thermal properties also mean faster heat dissipation during spring and fall, reducing the risk of ice dam formation during freeze-thaw cycles. The energy benefit isn't dramatic in a cold climate, but it's measurable and consistent.

Aluminum roofs end the asphalt tear-off-to-landfill cycle. At the end of Interlock's life, approximately 95% of the material is recyclable, and aluminum scrap holds genuine market value—recyclers actively seek it out. Asphalt shingles, by contrast, shed into landfills by the ton each year across Wisconsin, taking decades to decompose. Concord's high rainfall (775 mm annually) and freeze-thaw stress mean asphalt roofs wear out faster here, forcing earlier replacement and more frequent landfill contributions. Interlock's lifetime warranty and one-time transfer (50-year term for the next owner) mean one roof may serve two households, further reducing the environmental footprint. The ICC-ES evaluation (ESR-1790) includes CALGreen verification for reduced maintenance and material efficiency—a third-party confirmation of the sustainability advantage.

Yes. Concord averages about 88 cm of snow, 775 mm of rain, roughly 81 freeze–thaw days a year, with peak wind gusts near 100 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.
