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

Yes—aluminum is naturally immune to the freeze-thaw damage that degrades asphalt and wood. Avon experiences about 85 freeze-thaw days per year, where water enters cracks, freezes, expands, and splits materials from the inside. Aluminum's oxide layer doesn't absorb water, so expansion and contraction happen only on the surface where they cause no structural harm. The 3105-H24 / 3003-H24 aluminum alloy used in every Interlock panel has been installed successfully in far more extreme climates since 1998, including Antarctic research stations. Your roof simply won't crack, curl, or split from seasonal temperature swings.

Metal roofs shed snow and ice faster than asphalt because the smooth, hard surface offers no grip. With about 83 centimeters of snow per year in Avon, this matters: less weight lingering on the frame, and less dam-prone water flow in spring thaw. The four-way interlocking aluminum panels are warranted to resist wind gusts up to 120 mph (193 km/h)—far stronger than the typical 97 km/h gusts Avon sees—so snow guards (if you choose them for aesthetic control) stay firmly attached. The lightweight design (Slate profile at 0.41 lb/sq ft) means your roof handles the full winter load without structural strain, and installation over your existing roof requires no reinforcement.

Aluminum roofs cannot rust because aluminum contains no iron; it is the iron in steel that oxidizes into rust. Instead, aluminum forms a thin, self-healing oxide layer that actually protects the metal beneath. In Avon's climate—about 828 mm of rainfall per year and exposure to road salt in winter—this is a genuine advantage over steel. The Alunar® 70% PVDF fluorocarbon finish applied to both sides of every panel adds a second barrier, warranted 30 years against chalking and fading per ASTM standards. This dual protection means your roof resists corrosion through the entire roof's life, not just the warranty period.

Yes. The four-way interlocking design locks each panel on all four edges, creating a continuous structural grid that resists wind pressure and uplift. Avon's typical daily-max winds average about 19 km/h with gusts to 97 km/h; Interlock panels are warranted to resist winds up to 120 mph (193 km/h) when installed to specification. That 2x safety margin comes from the mechanical lock alone—no fastener pulling out under pressure, no panel edge lifting. The ICC-ES evaluation report ESR-1790 (reissued 2025) confirms this performance to code. Storm season is simply less of a worry.

Interlock metal roofing carries the UL 2218 Class 4 impact rating—the highest available—and the warranty even covers perforation from hailstones up to 1.5 inches. Class 4 means the roof has been tested with steel balls up to 2 inches, dropped from 20 feet, with zero leaks. In Avon's climate, where hail is a seasonal risk, this rating often qualifies for insurance discounts because the roof simply doesn't fail. Some homeowners report savings of 10–20% on premiums when they switch from asphalt. Contact your agent with the UL 2218 Class 4 rating to ask; many insurers recognize metal roofing as a loss-reduction upgrade worth rewarding.

No reinforcement is needed. Interlock's lightweight aluminum panels—the Slate at 0.41 lb/sq ft, the Mediterranean Tile at 0.59 lb/sq ft—weigh about 96% less than concrete or clay tile, and install directly over most existing roofs. A typical asphalt roof already weighs 2–3 pounds per square foot; aluminum weighs less, so your frame actually experiences no new load. The ICC-ES evaluation ESR-1790 confirms installation without structural upgrade in standard residential construction. In Avon, where 83 centimeters of snow per year adds seasonal weight, this matters: the roof sheds precipitation faster and puts less permanent strain on the frame than heavier materials ever could.

The Guardian warranty is a lifetime limited, non-prorated material warranty for the original owner—meaning no percentage reduction in coverage over time. It covers rusting, rotting, splitting, cracking, curling, and loss of impact resistance. When you sell, the warranty transfers once to the next owner for 50 years from completion, adding to your home's marketability. Interlock panels have been in service since 1998 across climates from coastal salt air to Antarctica, with many early installations still performing flawlessly after 25+ years. Combined with the 30-year coating warranty on the Alunar® finish, you're looking at a roof that outlasts three asphalt roofs by decades.

Over the roof's full life, metal costs significantly less. Asphalt requires replacement every 15–25 years; in Avon's climate with 85 freeze-thaw days and 83 centimeters of snow annually, the lower end is typical. Each tear-off and disposal costs money; each new installation costs labor. An Interlock roof installed once lasts 40–60 years or more, with no mid-life replacement. The lifetime limited warranty means you're not budgeting surprise repairs. Energy-efficient colors save on cooling costs, and the published solar-reflectance listing gives you measurable thermal performance. The math is simple: buy one roof now, or buy three asphalt roofs in the same timespan. Resale value typically recovers 60–70% of the metal roof cost.

Yes, and in Avon's climate they earn their keep. With about 3107 sunshine hours per year and summer days that do warm up, the thermal benefit is real. energy-efficient Interlock colors have initial solar reflectance up to 0.55 (Aged Copper Penny) and thermal emissivity of 0.84, meaning they bounce heat that dark asphalt absorbs. Cool Roof Rating Council testing confirms this performance. On a summer day, a reflective metal roof stays noticeably cooler than asphalt, reducing air-conditioning runtime and electricity costs. While Avon's 9.5°C mean temperature is cool overall, the reflective advantage accumulates across every sunny day of the year—and helps in winter by reducing unwanted heat loss through radiation.

Metal requires far less. Asphalt shingles curl, crack, and shed granules, especially under Avon's 85 annual freeze-thaw cycles; wood shakes and shingles rot, split, and harbor moss in wet climates. Aluminum panels don't degrade from moisture or temperature swings—the oxide layer and Alunar® 70% PVDF coating handle both. You'll rinse debris twice a year and check gutters, just as with any roof. Unlike wood, there's no painting, staining, or moss treatment. Unlike asphalt, there's no granule loss or curl to monitor. The ICC-ES evaluation confirms CALGreen verification for reduced maintenance requirements. Over a 50-year lifespan, this means far fewer service calls and zero emergency repairs from weather-induced splits or rot.

Yes. Avon averages about 83 cm of snow, 828 mm of rain, roughly 85 freeze–thaw days a year, with peak wind gusts near 97 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.
