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

Aluminum naturally resists freeze-thaw damage because it has no wood fibers to split or absorb water, and no iron to rust when moisture enters cracks. Edgerton experiences about 87 freeze-thaw days annually, which would cause wood shingles and asphalt to crack and curl over time. The 3105-H24 aluminum alloy used in Interlock panels won't degrade from repeated freezing—the oxidation layer that protects the metal actually self-heals when scratched, so even micro-damage from expansion and contraction stays sealed. That's why Interlock roofs have been installed from coastal salt-air environments to Antarctic research stations without material failure from temperature cycling.

No—metal roofs are excellent for snow climates because the smooth, slippery surface sheds snow efficiently, and the lightweight panels won't sag under load the way heavier materials do. Edgerton averages about 86 centimeters of snow per year, and the four-way interlocking system keeps panels locked together so snow movement won't separate seams. The real advantage: because Interlock panels weigh as little as 0.41 lb/sq ft (the Shingle profile), your existing roof structure almost always handles the installation without reinforcement—unlike slate or concrete tile, which would require costly structural upgrades. Ice dams are prevented through proper attic ventilation and underlayment, not the roofing material itself.

Yes—Interlock's four-way interlocking aluminum panels are warranted to resist winds up to 120 mph when installed to specification. Edgerton's typical wind gusts reach about 95 km/h (59 mph), well below that threshold, so your roof will remain secure through the region's strongest storms. The four-way lock means panels are connected on all sides, distributing wind load across the entire roof rather than stressing individual fasteners. This design, combined with proper fastening into the substrate, gives you significantly more wind resistance than asphalt shingles, which can lift and tear in sustained gusts above 45 mph. For long-term peace of mind, the interlocking system eliminates the progressive failure pattern common in shingle roofs.

Metal roofs often qualify for insurance discounts because Interlock panels carry a UL 2218 Class 4 impact rating—the highest available—and the warranty covers perforation from hailstones up to 1.5 inches. Contact your insurer for specific discount eligibility, but many homeowners see annual savings that partially offset the roof cost. Edgerton's climate includes spring and early-summer hail risk, and while no roofing material is completely hail-proof, the aluminum's rigid structure and high-impact rating provide far better protection than asphalt shingles, which are prone to bruising and cracking from smaller impacts. Unlike shingles, even impacts that don't perforate an Interlock panel won't degrade its ability to shed water or seal the roof.

Aluminum contains no iron, so it cannot rust—period. Steel roofing, by contrast, relies on paint or coating to prevent corrosion, and once that coating fails, rust accelerates. Interlock uses roofing-grade 3105-H24 aluminum alloy (ASTM B209) with a Alunar 70% PVDF fluorocarbon finish applied to both sides, warranted 30 years against chalking and fading. When aluminum is scratched, the oxide layer self-heals—forming a new protective barrier automatically. In Edgerton's wet climate, with about 788 mm of rain and 86 cm of snow per year, that self-healing property means your roof maintains its integrity year after year without the corrosion failures that plague steel. This is why Interlock roofs are installed in harsh salt-air environments without rust concerns.

In most cases, yes—Interlock's ultralight weight (as little as 0.41 lb/sq ft for the Shingle profile) allows installation directly over existing asphalt shingles without structural reinforcement. A solid deck with proper underlayment is required for weather-tight performance and to eliminate noise. The installation process typically takes 2 to 5 days depending on roof size and complexity. Your local Interlock installer has been serving the region since 2001 and will assess your specific roof during the inspection to confirm whether the existing structure supports direct installation or if a tear-off is necessary for optimal long-term performance. Going over existing shingles also means you avoid the landfill cost and environmental impact of a tear-off.

Interlock panels are warranted with The Guardian—a lifetime limited, non-prorated material warranty for the original owner that covers rusting, rotting, splitting, cracking, curling, and loss of impact resistance. That warranty is one-time transferable to the next owner for a 50-year term from completion. In real terms, you're buying the last roof you'll install on your home. Combined with the 30-year coating warranty against chalking and fading, and the aluminum's natural resistance to the freeze-thaw cycling that damages asphalt (Edgerton experiences about 87 freeze-thaw days yearly), a properly maintained metal roof typically lasts 50+ years with minimal intervention. No other residential roofing material offers this combination of coverage and lifespan.

Metal roofs require significantly less maintenance than asphalt shingles or wood shakes. Asphalt degrades from UV exposure and Edgerton's 3,093 annual sunshine hours; wood splits and curls from the region's 87 freeze-thaw cycles; metal simply sheds water and resists both. Your primary maintenance is clearing gutters and inspecting flashing after severe weather—no power washing, no fungicide treatments, no moss removal like wood-shake owners do. The Alunar 70% PVDF coating resists dirt accumulation, so rain naturally cleans the surface. This low-maintenance profile is why Interlock roofs are verified by CALGreen for reduced maintenance, and it translates directly to lower lifetime costs compared to asphalt shingles, which typically need replacement or expensive repairs every 15 to 20 years.

Yes, though the savings are more modest in Edgerton's cool climate than in hotter regions. energy-efficient Interlock colors achieve initial solar reflectance up to 0.55 and thermal emissivity of 0.84, meaning they reflect heat that asphalt absorbs and slowly releases—reducing attic temperature on sunny days. With about 3,093 sunshine hours annually in Edgerton, that reflection matters during summer months and shoulder seasons. Cool Roof Rating Council testing confirms the energy benefit. The real advantage in your climate is that light colors stay cooler to touch, reducing thermal stress on the aluminum (which further protects its structural integrity), and in winter, the low emissivity helps retain radiant heat from inside. Pair this with proper attic ventilation, and you'll see modest but measurable HVAC savings year-round.

Metal roofing eliminates the asphalt tear-off-to-landfill cycle that plagues shingle roofs. Interlock panels are approximately 95% recyclable, and because they can be installed over existing shingles in most cases, you avoid the disposal cost and environmental impact of tearing off your old roof. Asphalt shingles, by contrast, create millions of tons of landfill waste annually—a burden Edgerton contributes to with every roof replacement cycle. Aluminum is infinitely recyclable without degradation, so your roof can be reclaimed and reused at the end of its life, whether that's 50 years from now or beyond. If environmental responsibility factors into your decision, a metal roof is the most honest choice: no tear-off, no waste, and full recyclability at end of life.

Yes. Edgerton averages about 86 cm of snow, 788 mm of rain, roughly 87 freeze–thaw days a year, with peak wind gusts near 95 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.
