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

Yes—aluminum actually thrives in freeze-thaw conditions. Salem experiences about 80 freeze-thaw days per year, and aluminum's oxide layer doesn't crack, split, or degrade when water freezes and thaws in its surface. Unlike asphalt shingles, which become brittle and fracture over repeated cycles, or wood shakes, which split from ice expansion, aluminum simply expands and contracts uniformly. The roofing-grade 3105-H24 alloy (ASTM B209) is rated to ICC-ES ESR-1790 standards for exactly these climates. Your roof won't develop stress fractures or lose its integrity season after season.

Metal roofing sheds snow more effectively than asphalt because its smooth, interlocking surface provides fewer places for ice dams to form, and its superior reflectance (up to 0.55 solar reflectance on select energy-efficiency colors) means less radiant heat melts snow from below. Salem receives about 82 cm of snow annually, and the four-way interlocking panel design distributes weight evenly across your roof structure. The extraordinary lightness—Shake at 0.58 lb/sq ft—also means your framing carries less overall load. Optional snow guards can be installed if aesthetic snow slides are a concern for walkways below.

Completely safe—Interlock's four-way interlocking aluminum panels are warranted to resist wind speeds up to 120 mph when installed to specification. Salem's typical wind gusts reach about 99 km/h (about 62 mph), well within the system's rated capacity. The interlocking design means each panel locks to its neighbors on all four sides, distributing wind load across the entire roof rather than putting stress on individual fasteners. UL 2218 Class 4 impact certification and decades of installations in coastal salt-air environments confirm that this system handles severe weather reliably.

Aluminum cannot rust because it contains no iron—the element responsible for rust in steel. Instead, aluminum develops a thin, transparent oxide layer that actually protects the metal beneath. If that layer is scratched, it heals itself automatically when exposed to air. The Alunar 70% PVDF fluorocarbon finish (applied to both sides of every panel and warranted 30 years against chalking and fading) adds an extra protective barrier. With Salem's 835 mm annual rainfall and freeze-thaw exposure, you're eliminating the rust risk entirely—the roof won't degrade from moisture or salt exposure the way steel alternatives eventually do.

Your metal roof is the most hail-resistant roofing available: UL 2218 Class 4 impact rating (the highest classification) with warranty coverage for perforation from hailstones up to 1.5 inches. This non-combustible aluminum construction also qualifies for Class A fire rating, and many insurers offer discounts for impact-resistant and fire-rated roofing. Salem's climate brings occasional severe weather, and a roof that requires no replacement after hail events—unlike asphalt shingles—can translate to tangible insurance savings over decades. Contact your insurer with the UL 2218 Class 4 rating and ICC-ES ESR-1790 documentation to discuss your specific policy.

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 also one-time transferable to the next owner for 50 years from completion—a significant resale advantage. While asphalt shingles typically need replacement every 20–25 years and wood shakes every 30–40 years, aluminum roofing has installations dating back to 1998 (manufacturing began in Delta, BC) with no material degradation. In Salem's climate of about 80 freeze-thaw days yearly and moderate snow, this durability means your roof will outlast multiple replacement cycles of conventional materials.

Virtually none. Unlike asphalt shingles (which require periodic inspection, moss treatment, and debris removal), wood shakes (which split and need individual replacement), or tile (which cracks and needs resealing), aluminum roofing is CALGreen-verified for reduced maintenance. An occasional rinse during Salem's 835 mm annual rainfall keeps it clean; gutters need the same attention they would with any roof. The Alunar finish is rated to resist chalking and fading for 30 years (ASTM D4214/D2244), so color won't fade from the about 3,094 annual sunshine hours. No sealing, no spot repairs, no decay risk—just a roof that works quietly year after year.

Yes—Interlock offers five authentic profile options: Slate, Cedar Shingle, Shake, Mediterranean Tile, and Standing Seam. Each replicates the visual depth and texture of its namesake material while delivering aluminum's durability, weight savings (the Tile profile is about 96% lighter than concrete or clay tile), and maintenance freedom. You choose the look that matches your home's architecture and Salem's neighborhood character, then enjoy the performance advantages: no cracking from freeze-thaw, no rotting from moisture, and a 30-year finish warranty. These profiles are available in multiple colors, so your curb appeal doesn't require a trade-off with longevity.

Over the full lifespan of your roof, metal roofing is significantly more cost-effective. Asphalt requires replacement every 20–25 years; a typical home might need 2–3 replacements over 60–75 years, including labor, tear-off disposal, and potential structural repairs. Metal roofing installed once lasts longer than the house itself, carries a lifetime limited warranty (non-prorated for the original owner), and transfers with 50 years of coverage to the next owner. Additionally, energy-efficient colors can reduce cooling costs with solar reflectance up to 0.55 and thermal emissivity of 0.84. When you total avoided replacement cycles and labor, plus energy savings and the resale value premium, a single metal roof installation becomes the last roof you'll need to buy.

Yes—one of aluminum's key advantages is its extraordinary lightness. The Shake profile at 0.58 lb/sq ft and the Tile at 0.59 lb/sq ft (about 96% lighter than concrete or clay tile) mean no structural reinforcement is needed and installation can proceed over most existing roofs, eliminating costly tear-off and landfill disposal. The four-way interlocking panel system allows faster installation than traditional materials because each panel locks securely to its neighbors, reducing fastening points and potential weak spots. Interlock Metal Roofing has served the Kenosha County region since 2001 and can provide a detailed timeline once they assess your home's specific conditions and existing roof structure.

Yes. Salem averages about 82 cm of snow, 835 mm of rain, roughly 80 freeze–thaw days a year, with peak wind gusts near 99 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.
