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

Interlock panels shed snow and ice effectively because their smooth aluminum surface and interlocking design prevent water from pooling where freeze-thaw cycles can cause damage. Palmyra receives about 88 cm of snow annually across roughly 81 freeze-thaw days, creating conditions where traditional asphalt shingles crack and curl. The panels' lightweight profile means no structural reinforcement is needed, and optional snow guards are available if you want to control roof runoff. The aluminum oxide layer self-heals when scratched by ice movement, keeping the protective barrier intact year after year.

No—aluminum thrives through freeze-thaw stress because it expands and contracts uniformly without cracking or splitting. Palmyra experiences about 81 freeze-thaw days per year with average annual snowfall near 88 cm, yet the material's intrinsic properties make it indifferent to temperature swings. Unlike asphalt shingles, wood, or concrete tile, roofing-grade 3105-H24 aluminum alloy (ASTM B209) has no moisture absorption pathways, so ice cannot form inside the material and fracture it from within. The Alunar 70% PVDF coating, warranted 30 years against degradation, adds a second line of defense against the salt and corrosive runoff common after winter weather.

Yes—the lightweight profile is one of aluminum's greatest advantages. The Shake profile installs at just 0.58 lb/sq ft and the Mediterranean Tile at 0.59 lb/sq ft, making the latter about 96% lighter than a concrete or clay tile roof. This means no structural reinforcement is required, and the panels can install directly over most existing asphalt roofing. Removing old shingles costs money and creates landfill waste; installing over them saves both. The four-way interlocking system holds everything secure even with Palmyra's typical wind gusts near 100 km/h, so lightness does not compromise durability.

Yes—the four-way interlocking aluminum panels are warranted to resist wind speeds up to 120 mph (193 km/h) when installed to specification. Palmyra's typical wind gusts average around 100 km/h, well within the roof's rated capability. The interlocking design means wind cannot lift or separate individual panels; each locks to its neighbor on all four sides. Independent testing under UL 2218 Class 4 impact standards demonstrates the panels' ability to endure hail up to 1.5 inches, which often accompanies severe wind events. This combination of wind and impact warranty gives you peace of mind during the spring and fall storm season.

Many insurers offer discounts for roofs with UL 2218 Class 4 impact rating—the highest available—which Interlock metal roofing achieves. The warranty covers perforation from hailstones up to 1.5 inches, and the panels' non-combustible aluminum construction qualifies for Class A fire ratings in most markets. Contact your agent with the ICC-ES evaluation report ESR-1790 and the Guardian Warranty details; both documents support a discount application. Spring and summer storms in Palmyra, with wind gusts to 100 km/h, often bring hail, so demonstrating impact resistance to your insurer can translate into real savings over the roof's 50-year transferable term.

energy-efficient Interlock colors with thermal emissivity of 0.84 and initial solar reflectance up to 0.55 reflect heat that asphalt absorbs, reducing cooling demand. Palmyra receives about 3,074 sunshine hours per year; during warm months, this reflectance matters. The Cool Roof Rating Council certification confirms measured performance. Unlike asphalt, which darkens and absorbs more solar energy over time, the Alunar fluorocarbon coating maintains its reflectivity for 30 years. While Palmyra's 9°C average temperature is mild, spring and summer heat spikes still add to air-conditioning load, and a reflective roof lowers that burden without changing your home's appearance.

The Guardian Warranty is a lifetime limited, non-prorated material warranty for the original owner, covering rusting, rotting, splitting, cracking, curling, and loss of impact resistance. It is transferable once to the next owner for 50 years from completion date. The Alunar fluorocarbon coating alone is warranted 30 years against chalking and fading (ASTM D4214 / D2244 measured). Combined with the aluminum's intrinsic durability through Palmyra's ~775 mm annual rainfall and 81 freeze-thaw days, and installed by the local team since 2001, you're buying the last roof you'll need. Compare this to asphalt shingles, which typically require replacement every 15–20 years.

Interlock aluminum roofs are virtually maintenance-free. No periodic coating reapplication, no moss treatment, no crack repair—unlike asphalt shingles, wood shake, or clay tile. The CALGreen-verified design for reduced maintenance means you inspect gutters and flashing annually but not the roofing material itself. Palmyra's ~775 mm annual rainfall keeps the roof naturally clean; the Alunar fluorocarbon finish, warranted 30 years, resists dirt adhesion and UV degradation. Asphalt shingles deteriorate annually and need preventive maintenance; wood splits and curls in freeze-thaw cycles; tile cracks from impact. Aluminum's oxide layer self-heals minor scratches. This freedom from maintenance protects your time and your wallet.

Yes—Interlock aluminum is approximately 95% recyclable and breaks the asphalt tear-off-to-landfill cycle. When an asphalt roof reaches end of life, the shingles become construction waste destined for disposal; aluminum panels return to the recycling stream and become new products. Installed over your existing roof, there's no tear-off waste to begin with, saving landfill volume and hauling emissions. The panels' durability means fewer roof replacements over a 50-year period, reducing total lifecycle environmental impact. Manufactured since 1998 in Delta, BC, and installed worldwide from coastal homes to Antarctic research stations, the supply chain is established and efficient. For environmentally conscious Palmyra homeowners, this is a concrete way to reduce your home's footprint.

Interlock Metal Roofing, the manufacturer and authorized installer, has served the Palmyra region and Jefferson County since 2001.

They're familiar with local building codes (ICC-ES ESR-1790 compliant) and can coordinate permits, inspections, and installation over your existing roof without disruption. Because Interlock manufactures the panels in Delta, BC, and installs them directly, you're working with the source, not a middleman distributor. Call for a consultation; they'll assess your roof, explain the five profiles available, and guide you through the process.

Yes. Palmyra averages about 88 cm of snow, 775 mm of rain, roughly 81 freeze–thaw days a year, with peak wind gusts near 100 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.
