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

Yes — aluminum is naturally immune to freeze-thaw damage because it contains no iron and cannot rust or corrode. Sussex experiences about 79 freeze-thaw days per year, plus roughly 88 cm of snow, conditions that devastate wood shingles, asphalt, and steel. The Alunar 70% PVDF coating on both panel sides adds a second defense layer, warranted 30 years against degradation. Aluminum expands and contracts predictably; the four-way interlocking system accommodates movement without leaking or failing.

Interlock's weight advantage changes everything in snow country. The Cedar Shingle profile weighs just 0.41 lb/sq ft — light enough that seasonal snow loads (averaging 88 cm annually) never demand structural reinforcement, unlike slate or clay tile. The smooth, sloped panels naturally shed snow and ice without buildup; when combined with optional snow guards, the system manages both the weight and the water that follows spring melt. No buckling, no collapse risk, no costly roof bracing needed.

Interlock panels are warranted to resist winds up to 120 mph, and Sussex's typical gusts average around 96 km/h — well within that safety margin. The four-way interlocking design locks each panel to its neighbors on all sides, creating a unified system that distributes wind load across the entire roof rather than relying on fasteners alone. This redundancy is why the panels perform consistently even in the stronger seasonal gusts Waukesha County experiences.

Steel rusts because it contains iron; aluminum cannot rust at all because it contains zero iron. Instead, aluminum develops a transparent oxide layer that actually self-heals when scratched — a built-in defense that works year after year. In Wisconsin's 822 mm of annual rainfall, this matters enormously. The Alunar 70% PVDF fluorocarbon coating (applied to both sides) adds a second protective layer warranted 30 years against chalking and fading, giving you genuine dual protection that steel roofing simply cannot match.

Metal roofing is the last roof you buy; asphalt is not. Asphalt typically lasts 15–20 years in Wisconsin's climate (88 cm snow, 822 mm rain, 79 freeze-thaw days annually), requiring multiple replacements over a homeowner's tenure. Interlock's lifetime limited warranty for the original owner — non-prorated for material defects — eliminates replacement costs and tear-off disposal fees. Energy-savings potential also compounds: energy-efficient colors achieve thermal emissivity of 0.84, reducing summer cooling loads in those ~3128 annual sunshine hours. One installation, one expense, decades of protection.

The Guardian Warranty is a lifetime limited, non-prorated material warranty for the original owner — no degradation, no coverage caps. It covers rusting, rotting, splitting, cracking, curling, and loss of impact resistance. The next owner receives a one-time transferable coverage lasting 50 years from completion, incentivizing long-term stewardship. This structure reflects the reality that aluminum roofing outlasts asphalt by decades. In Sussex's demanding climate—with freeze-thaw cycling, heavy snow, and frequent wind gusts—you're protected for the life you plan to stay and beyond.

Interlock achieves UL 2218 Class 4 impact rating, the highest available hail classification. The warranty even covers perforation from hailstones up to 1.5 inches. This rating often qualifies homeowners for insurance discounts — check with your agent — because the roof rarely files a claim. Class 4 aluminum roofing typically requires repairs far less frequently than asphalt or composition shingles in Wisconsin hail events. The four-way locking system also means isolated impact damage doesn't compromise the entire roof's water-shedding ability.

Yes. The Mediterranean Tile profile weighs approximately 0.59 lb/sq ft — about 96% lighter than concrete or clay tile — so no structural reinforcement is required. You can often install directly over your existing asphalt roof, avoiding tear-off labor and landfill disposal fees. This also minimizes interior disruption and shortens installation timelines. Lighter weight means old framing and trusses, however modest their capacity, typically accommodate the load without engineering upgrades. Always confirm with your installer, but aluminum tile eliminates the structural barrier that keeps many homeowners from the traditional tile aesthetic.

Aluminum roofing breaks the disposable-shingle cycle. Interlock panels are approximately 95% recyclable at end-of-life and end the asphalt tear-off-to-landfill routine entirely. Asphalt shingles accumulate in landfills; aluminum retains value and moves into new manufacturing streams. Over a 40-year service life in Sussex — with its 822 mm annual rainfall and 88 cm snowfall requiring reliable protection — you avoid four or five asphalt replacements and their associated disposal impact. The environmental accounting strongly favors one durable roof over the cumulative waste of multiple temporary ones.

Factory backing also means warranty claims and technical questions go directly to the people who built your roof. Local expertise plus direct accountability.

Yes. Sussex 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.
