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

Metal roofs shed snow and ice far more effectively than asphalt because the smooth, hard surface doesn't create friction — snow slides off instead of accumulating. With about 105 cm of snow annually in Kewaskum, this matters: your roof stays lighter, ice dams form less often, and you avoid the weight stress asphalt absorbs. The four-way interlocking panels won't separate or lift under freeze-thaw cycling, which occurs roughly 84 days per year here. Add optional snow guards if you need controlled shedding near walkways.

No — aluminum's oxide layer actually thrives through freeze-thaw cycles. Unlike asphalt (which gets brittle and cracks) or wood (which rots), aluminum expands and contracts without degradation. Kewaskum experiences about 84 freeze-thaw days yearly; the Alunar 70% PVDF coating bonds to the aluminum and remains flexible across that range. The Guardian Warranty covers cracking and splitting for the life of the roof because the material doesn't develop those defects. Asphalt typically fails within 15 to 20 years in this climate.

Aluminum cannot rust because it contains no iron — the element that oxidizes and corrodes. Instead, aluminum forms a self-healing oxide layer that actually protects the metal underneath. With Kewaskum receiving about 726 mm of rain per year, this distinction is real: steel roofs develop rust stains and eventually perforate, while aluminum stays sound. The Alunar 70% PVDF coating (applied to both sides) adds a 30-year fade and chalk warranty. After 30 years, even if the coating weathers, the aluminum substrate remains non-corrosive.

Interlock's four-way interlocking system is warranted to resist wind speeds up to 120 mph when installed to spec — well beyond Kewaskum's typical gust speeds of about 101 km/h. The panels lock together on all four sides, so wind pressure can't separate or lift them. Ice storms won't stress the seams either: the panels flex slightly as snow and ice slide off, but the interlocks stay tight. Compare this to asphalt shingles, which separate and curl in high wind. Local installers have been securing these systems for over 20 years.

Interlock metal roofing carries a UL 2218 Class 4 impact rating — the highest available — and the warranty even covers perforation from hailstones up to 1.5 inches. Many Wisconsin insurers recognize this durability and offer premium discounts for Class 4 metal roofs. Your homeowner's agent can confirm your local discount; some customers report 10–20% reductions. Because the roof won't need frequent repairs or replacement after hail events (as asphalt roofs do), you'll also avoid the hassle of claims over 20-plus years. Ask your installer about coordinating with your insurer.

Not only can your frame support it — aluminum's light weight often means you avoid structural reinforcement entirely. The Shake profile weighs just 0.58 lb/sq ft, and the Mediterranean Tile (which replicates real clay or concrete tile) weighs approximately 0.59 lb/sq ft — about 96% lighter than actual tile. Most homes can install over an existing roof with zero structural upgrades. By contrast, slate, clay, or concrete tile roofs typically require additional framing reinforcement costing thousands of dollars. Your installer will verify your deck during the site visit, but in nearly all cases, Kewaskum homes already meet the spec.

Aluminum metal roofing requires almost no maintenance — no more than you'd do for asphalt, and far less than wood shake or tile. You don't re-coat it, seal it, or replace individual shingles. Twice yearly, inspect gutters and downspouts (standard practice in any climate); brush off heavy debris after storms. The Alunar finish is rated for 30 years against chalking and fading (ASTM D4214), so color remains stable through Kewaskum's 3,113 sunshine hours per year and roughly 105 cm of annual snow. Compare this to asphalt, which requires moss treatment and re-sealing, or wood shake, which rots in Wisconsin's 84 freeze-thaw days.

Yes — energy-efficient Interlock colors feature thermal emissivity of 0.84 and solar reflectance up to 0.55, meaning they bounce heat away that asphalt would absorb and trap. Over a year with roughly 3,113 sunshine hours in Kewaskum, this adds up. Darker metal roofs stay cooler than dark asphalt; lighter colors reduce cooling load substantially. The Cool Roof Rating Council certifies these reflectance values. You won't see AC running as hard on hot days, and the slight cooling benefit carries year-round. Heating costs are similar to asphalt (both sit above the insulation layer), but summer energy savings are real.

Choosing aluminum ends the cycle of tearing off worn asphalt and sending it to a landfill every 15–20 years. Interlock panels are approximately 95% recyclable — at end of life, the entire roof goes back into the aluminum supply chain instead of a dump. Over 50 years (the transfer warranty term), you replace an asphalt roof three times, each time creating waste. One aluminum roof lasts longer and never needs replacement. Kewaskum sees enough rainfall (726 mm per year) and freeze-thaw stress (84 days yearly) that asphalt fails faster here than in mild climates — meaning more landfill waste per homeowner. Aluminum breaks the waste cycle.

Interlock metal roofing is backed by The Guardian Warranty — a lifetime limited, non-prorated material warranty for the original owner. It covers rusting, rotting, splitting, cracking, curling, and loss of impact resistance. When you sell, the warranty transfers once, giving the next owner 50 years from roof completion. In practical terms, most homeowners install once and never replace the roof. The Alunar coating carries an explicit 30-year fade and chalk warranty. Contrast this to asphalt shingles, which fail in 15–20 years in Wisconsin's climate (with 84 freeze-thaw days and ~105 cm snow annually), requiring full replacement and disposal.

Yes. Kewaskum averages about 105 cm of snow, 726 mm of rain, roughly 84 freeze–thaw days a year, with peak wind gusts near 101 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.
