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

Interlock's aluminum panels shed snow and ice far better than asphalt because their smooth, hard surface won't trap moisture — critical in a climate that averages about 105 cm of snow annually and experiences roughly 84 freeze-thaw days per year. The four-way interlocking design and lightweight construction mean no sagging under load, and the panels' thermal conductivity helps prevent ice dams. You can add snow guards to any profile if you prefer managed shedding.

No — aluminum's oxide layer actually strengthens with exposure to freeze-thaw cycling rather than degrading. Unlike asphalt shingles that become brittle and crack after 84+ annual thaw cycles like Lyndon experiences, or wood that splits, aluminum 3105-H24 alloy is engineered to flex and remain intact. The Alunar 70% PVDF coating (warranted 30 years against chalking) protects the surface through decades of Wisconsin winters.

Aluminum cannot rust because it contains no iron — the element that corrodes. Instead, a paper-thin oxide layer forms naturally on the surface and heals itself when scratched. Sheboygan County's 726 mm of annual rainfall means constant moisture exposure, but your Interlock roof will never develop the rust stains, perforation, or structural decay that plague steel roofing in wet climates. The Alunar finish on both sides adds an extra 30-year durability layer.

Yes — Interlock's four-way interlocking aluminum panels are warranted to resist sustained winds up to 120 mph, and Lyndon's typical gusts reach about 101 km/h (63 mph), well within that range. The panels lock on all four edges, distributing uplift forces evenly across the roof rather than concentrating stress on fasteners. In severe weather with heavy snow loading plus wind, this design keeps panels seated and watertight when traditional shingles lift or tear.

Interlock achieves UL 2218 Class 4 impact rating — the highest available — and the Guardian Warranty even covers perforation from hailstones up to 1.5 inches. This rating, combined with aluminum's non-combustible properties and Class A fire availability, often qualifies homeowners for insurance discounts on both wind and impact coverage. Talk to your agent; many insurers recognize the durability and file a claim less frequently than they do for asphalt roofs.

No structural reinforcement is needed. Interlock's aluminum panels are extraordinarily light — the Slate and Shake profiles install at roughly 0.41–0.58 lb/sq ft, and the Mediterranean Tile profile is about 96% lighter than traditional concrete or clay tile. Most homes can install Interlock over an existing roof without any foundation or framing upgrades. This means lower labor costs and faster installation, plus your home's bones are never strained.

Minimal — far less than asphalt, wood, or tile. Aluminum won't rot, split, curl, or become brittle from Lyndon's 3113 annual sunshine hours and freeze-thaw stress. A simple annual rinse to remove debris is usually enough; gutters stay cleaner because the smooth surface sheds leaves and dirt. Asphalt requires regular granule replacement and sealing; wood requires staining and repair. Interlock's Alunar coating is CALGreen-verified for reduced maintenance, so you spend time enjoying your home instead of maintaining the roof.

Over a 40–50 year period, Interlock costs less than replacing asphalt three or four times. An asphalt roof lasts 15–20 years in Wisconsin's climate and ends up in a landfill; Interlock's Guardian Warranty covers the original owner for life (non-prorated for material defects), plus it transfers to the next owner for 50 years from completion. That means one installation cost versus multiple tear-offs, disposal fees, and labor restarts. When you calculate total cost-per-year of ownership, aluminum wins decisively.

Yes — Interlock aluminum is about 95% recyclable at end of life, versus asphalt shingles that are torn off and landfilled. Wisconsin generates hundreds of millions of pounds of roofing waste annually, and aluminum breaks the tear-off-and-replace cycle. Even before recycling, your roof stays on the home for 50+ years instead of clogging landfills every 15–20 years. Choosing Interlock cuts your roofing environmental footprint by 70–80% over your ownership period.

Interlock Metal Roofing has served the region since 2001 — over two decades of installations, warranty support, and local reputation in Sheboygan County. The company manufactures all panels in Delta, BC (since 1998) and works with experienced local crews familiar with Wisconsin snow, wind, and moisture conditions. When you choose a local installer with deep regional experience, you're not relying on a distant contractor who may never return for warranty work.
