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

Yes. Aluminum roofing is engineered for climates with severe freeze-thaw stress. Hanover experiences about 85 freeze-thaw days yearly, where repeated expansion and contraction crack asphalt and cause wood to split and curl. Aluminum's crystal structure and lack of organic binders mean it flexes without degradation. The four-way interlocking system accommodates movement, and the Alunar 70% PVDF coating—warranted 30 years against cracking and peeling—protects the oxide layer that naturally heals when scratched. Your roof won't develop the splits and curling that plague asphalt over a Wisconsin winter cycle.

Metal roofs excel in snow country. Hanover averages about 81 cm of snow annually—enough to test any roof's durability. The Interlock Shake profile, for example, weighs only 0.58 lb/sq ft, so snow and ice load your structure far less than concrete or clay tile would; no reinforcement needed. The smooth, sealed interlocking panels shed snow and meltwater efficiently, reducing ice dam formation at the eaves. Optional snow guards can be installed for architectural control. The lightweight design means your existing framing handles winter moisture without risk of sagging or structural strain that heavier roofing creates.

Yes. Hanover's typical gusts reach 97 km/h, and Interlock's four-way interlocking aluminum panels are warranted to resist winds up to 120 mph (193 km/h) when installed to specification. Each panel locks to its neighbors on all four sides, distributing wind load across the entire roof system rather than concentrating stress on fasteners. The design passes UL 2218 Class 4 impact testing—the highest available—and the engineered anchor points are engineered to exceed local wind code. Even in severe spring and fall storms, your roof remains secure without the fastener pull-through failures that plague lighter asphalt or thinner metal systems.

Aluminum cannot rust because it contains no iron—the element that oxidizes and creates rust. Instead, aluminum develops a thin, transparent oxide layer that actually protects the metal beneath. If that layer is scratched, it self-heals in the presence of oxygen and moisture. Hanover receives about 863 mm of rain and 81 cm of snow annually, exposing your roof to constant moisture; steel roofing would rust through within years. The Alunar 70% PVDF fluorocarbon finish applied to both sides adds a 30-year warranted barrier against corrosion. The result: a roof that outlasts multiple asphalt cycles without rust stains or structural decay.

Hail is less of a risk to aluminum than to asphalt. Interlock metal roofing carries a UL 2218 Class 4 impact rating—the highest available—and the warranty covers perforation from hailstones up to 1.5 inches. Class 4 rating means your roof shrugs off impacts that dent or puncture asphalt shingles and create insurance claims. Some insurers recognize this durability and offer modest discounts on homes with Class 4-rated roofing. Even if a severe hailstorm strikes Hanover, your roof's aluminum construction and impact resistance mean fewer repairs, lower claim frequency, and potentially better insurance terms over the roof's 50+ year life.

Yes, when you select an energy-efficient color. Interlock offers profiles in colors with thermal emissivity up to 0.84 and solar reflectance up to 0.55 (Aged Copper Penny), rated by the Cool Roof Rating Council. These colors reflect sunlight that asphalt absorbs, keeping your attic cooler and reducing air-conditioning load on hot days. Hanover receives about 3,079 hours of sunshine annually—meaningful enough that reflective roofing cuts cooling energy by 10–15% in summer-heavy climates, and even modest gains add up over decades. The thermal benefit persists year-round: less heat absorbed means less thermal stress on the roof itself, reducing material fatigue from daily temperature swings.

Yes. The Interlock Mediterranean Tile profile weighs only about 0.59 lb/sq ft—roughly 96% lighter than concrete or clay tile—so it installs directly over most existing asphalt roofing without structural upgrades. Your home's framing was designed to carry asphalt; metal tile weighs a fraction of that, leaving your beams and trusses with substantial safety margin. This also means no costly reinforcement costs before installation. You avoid the tear-off labor and landfill fees that slate or tile alternatives require. The lightweight design is especially valuable in Hanover, where about 81 cm of annual snow adds weight; lighter roofing means your structure handles winter loading more safely.

Metal roofing requires almost none. Asphalt shingles need regular moss and algae treatment, gutter cleaning after every rain and snowmelt cycle, and periodic fastener re-sealing—tasks that compound over decades. Wood shakes split and curl, requiring repair or replacement of individual boards; asphalt absorbs moisture and rots at the core. Aluminum roofing sheds water and debris by design; the sealed interlocking joints eliminate gaps where moss and moisture hide. Hanover's 863 mm annual rainfall and 81 cm snow mean your roof faces constant moisture exposure—exactly where asphalt and wood falter and aluminum excels. A simple rinse with a hose once or twice a year keeps your Interlock roof clean; you'll spend far less on maintenance over the roof's lifetime.

Interlock offers The Guardian Warranty: a lifetime limited, non-prorated material warranty for the original owner covering rusting, rotting, splitting, cracking, curling, and loss of impact resistance. The warranty is one-time transferable to the next owner for 50 years from completion—a term that reflects the roof's actual durability. Because aluminum cannot rust and the Alunar 70% PVDF coating is warranted 30 years against chalking and fading, the roof typically lasts 40–60 years with minimal intervention. That lifespan means you're buying your last roof; you'll never tear off and replace it as you would asphalt every 15–20 years. The transferability adds resale appeal—the next owner inherits decades of remaining protection.

Installation typically takes 1–3 days depending on roof size and complexity—much faster than asphalt tear-off-and-replace jobs that span a week or more. Because Interlock panels are lightweight (0.41–0.59 lb/sq ft) and four-way interlocking, they install directly over most existing asphalt roofing. No tear-off means no dumpster fees, no disposal labor, and minimal disruption to your home. The installer will inspect your existing deck for rot or damage, install underlayment and flashing, then lay panels from the eave upward, locking each to its neighbor. The process is cleaner and faster than traditional roofing, and your home stays dry throughout. Interlock Metal Roofing has been serving the Hanover region since 2001, with crews trained in the specific installation sequence and local code requirements.
