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

Yes. Roxbury experiences about 84 freeze-thaw days per year, and aluminum's non-porous structure means water cannot penetrate and expand inside the material the way it does in asphalt or wood shakes. Asphalt shingles crack and curl as moisture freezes and thaws; aluminum simply sheds water. The Alunar 70% PVDF coating on both sides of every panel prevents moisture absorption at the edges, so repeated temperature swings—from well below zero to above freezing—won't degrade the roof. This is why aluminum roofs installed in harsh continental climates outlast traditional materials by decades.

Aluminum sheds snow efficiently because its smooth interlocking panels and sloped profile prevent buildup. With about 89 cm of snow annually in Roxbury, a metal roof's low friction means snow slides or sheds before it accumulates into the weight and ice-dam problems that trap meltwater under asphalt. The four-way interlocking system keeps panels locked together during snow load and thaw cycles; optional snow guards can control slide speed on steeper pitches. Aluminum weighs just 0.41 lb/sq ft for the Slate profile—so light it installs over existing roofs—meaning no structural concerns even with seasonal snow loads.

Absolutely. Roxbury's typical daily-max winds reach about 20 km/h, with gusts documented to 104 km/h—well within the capability of Interlock's four-way interlocking panels. The aluminum roof is warranted to resist wind speeds up to 120 mph (193 km/h) when installed to specification, and the interlocking design means each panel is mechanically fastened and locked to its neighbors, not just nailed. This system has protected coastal salt-air homes and Antarctic research stations; Wisconsin's seasonal wind events are far less severe. Your roof will remain secure through any storm Dane County weather produces.

No structural reinforcement is needed. Interlock's aluminum panels are extraordinarily light—the Mediterranean Tile profile installs at just 0.59 lb/sq ft, about 96% lighter than concrete or clay tile. Most roofs in Roxbury were built to support asphalt shingles (10–15 lb/sq ft) or slate, so aluminum typically installs over existing roofs without any structural modification. This lightweight advantage means you avoid the cost of beam reinforcement, and the roof can be installed directly over old shingles in many cases, eliminating tear-off labor and landfill fees. ICC-ES ESR-1790 confirms code compliance for residential installations.

Yes. Roxbury receives about 3089 sunshine hours per year, and energy-efficient Interlock colors reflect solar heat rather than absorbing it the way asphalt does. Reflectance ratings reach up to 0.55 for some profiles, with thermal emissivity of 0.84, meaning less heat transfers through the roof to your attic and living spaces. Cool Roof Rating Council certification confirms these reflective properties. In summer months, this reduces air-conditioning load; in winter, the light color won't negate your insulation. The cumulative cooling savings over a 50-year roof life add up significantly compared to dark asphalt that absorbs heat.

Interlock aluminum roofs carry a UL 2218 Class 4 impact rating—the highest available—and the Guardian Warranty even covers perforation from hailstones up to 1.5 inches. Class 4 rating demonstrates the four-way interlocking panels' durability under extreme impact. This superior rating often qualifies homeowners for insurance premium discounts compared to asphalt, which typically rates Class 1 or 2. Document the UL 2218 Class 4 listing and ICC-ES ESR-1790 evaluation when filing claims or requesting rate reviews; insurers recognize this as genuine durability, not marketing.

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's one-time transferable to the next owner for 50 years from completion—a substantial advantage when selling your home in Dane County's competitive market. Because aluminum cannot rust and the roof installs over existing shingles, eliminating costly tearoffs, the total cost of ownership over 40–50 years is typically less than two asphalt roofs plus two complete tear-offs and disposal fees.

Minimal. Unlike asphalt shingles that crack and curl, or wood shakes that split and rot—especially in Wisconsin's 84 freeze-thaw days annually—aluminum requires no repairs, sealants, or seasonal treatment. Gutters and nearby vegetation need the same cleaning as any roof, but the panels themselves are maintenance-free. The Alunar 70% PVDF coating is CALGreen-verified for reduced maintenance and is warranted 30 years against chalking and fading per ASTM D4214 and D2244. You never power-wash, seal, or replace individual shingles.

Interlock Metal Roofing has served the Roxbury and surrounding Dane County region since 2001—over two decades of local installation experience. Our team understands Wisconsin's freeze-thaw cycling, heavy snow and rain (about 89 cm snow and 781 mm rain yearly), and wind exposure. We install all five profiles—Slate, Cedar Shingle, Shake, Standing Seam, and Mediterranean Tile—directly over existing roofs in most cases. Contact us for a site evaluation and warranty quote; we handle every detail from ice-and-water barrier placement to final interlocking verification.

Yes. Interlock aluminum is approximately 95% recyclable at end of life; old asphalt roofs end up in landfills where they remain for decades. Installing over existing shingles means no immediate tear-off waste or labor. Aluminum's 50+ year lifespan eliminates the asphalt cycle of tear-off, disposal, and replacement every 15–20 years—which compounds disposal volume over time. Manufactured in Delta, BC since 1998, the panels are engineered for longevity rather than replacement, and the non-prorated lifetime warranty reflects confidence in durability. One aluminum roof over Roxbury's 3089 annual sunshine hours delivers far less environmental cost than multiple asphalt cycles.

Yes. Roxbury averages about 89 cm of snow, 781 mm of rain, roughly 84 freeze–thaw days a year, with peak wind gusts near 104 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.
