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

Yes—aluminum oxide doesn't degrade when water freezes and thaws in it, which happens about 80 days a year in Sturtevant. Asphalt becomes brittle in cold and cracks; wood shingles split as moisture cycles in and out. Interlock's 3105-H24 aluminum alloy stays dimensionally stable through those freeze-thaw swings, and its self-healing oxide layer means scratches don't become entry points for water. The roofing-grade material simply doesn't absorb moisture the way organic materials do.

Metal sheds snow and ice faster than asphalt because its smooth surface and excellent thermal properties (emissivity 0.84) radiate away ground heat efficiently, reducing ice dam formation. Sturtevant averages about 82 cm of snow annually—a four-way interlocking panel system stays watertight even when ice temporarily blocks the gutter line. The panels themselves weigh only 0.41 lb/sq ft (Slate profile), so you're not adding structural burden, and optional snow guards can slow slides where needed. Aluminum's thermal conductivity means less trapped heat means fewer dams.

No upgrades needed—that's one of metal roofing's biggest advantages. Interlock's Mediterranean Tile profile weighs about 0.59 lb/sq ft, roughly 96% lighter than real concrete or clay tile, so it installs over most existing roofs without reinforcement. Compare that to asphalt (around 3 lb/sq ft) or slate (7 lb/sq ft), and you're actually reducing the load on your home's framing. A roofer can install the system directly over your existing decking in most cases, which also saves you the cost of a full tear-off and landfill disposal.

Sturtevant's typical gusts reach about 99 km/h, and Interlock panels resist wind speeds up to 120 mph (193 km/h) when installed to spec—a warranty-backed guarantee. The four-way interlocking design creates a unified system where each panel locks to its neighbors, resisting uplift and lateral pressure as one unit. That's engineered to meet ICC-ES ESR-1790 (the current IBC/IRC standard), and it's the reason the system has been installed from coastal salt-air homes to an Antarctic research station. You won't have shingles lifting or splitting in a spring nor'easter.

Many insurers offer discounts for Class 4 impact-rated roofing, and Interlock carries UL 2218 Class 4 certification—the highest rating available. The warranty even covers perforation from hailstones up to 1.5 inches, which is genuine peace of mind. In Wisconsin, where spring hail is possible and insurance premiums stay high, a documented Class 4 rating can reduce your annual cost significantly—your agent can run a quote once the roof is installed. It's worth asking your insurer about the discount before you commit.

energy-efficient Interlock colors reflect rather than absorb solar heat, with initial solar reflectance up to 0.55 (Aged Copper Penny) and thermal emissivity of 0.84. Sturtevant gets about 3,094 sunshine hours per year, so that reflectance matters. While Racine County's mean temperature is cool (9.9°C annually), summer days still warrant cooling, and a reflective roof significantly outperforms dark asphalt, which absorbs heat and radiates it into the attic. A Cool Roof Rating Council rating backs these numbers. You'll see the real payoff in lower air-conditioning runtime, especially in July and August.

It's the last roof you'll buy. Asphalt lasts 15–20 years and requires replacement in your lifetime; Interlock carries a lifetime limited, non-prorated material warranty for the original owner (transferable to the next owner for 50 years). Over 40 years, asphalt costs roughly three times as much in cumulative replacement, labor, and disposal fees. Metal also eliminates the asphalt tear-off-to-landfill cycle entirely—Interlock is about 95% recyclable. When you factor in energy savings from thermal reflectance and zero maintenance versus gutter cleaning and shingle repairs, the lifetime cost favors metal decisively.

Almost none. Unlike asphalt, which degrades from UV and cracks in Wisconsin's 80 annual freeze-thaw days, or wood shakes, which split and rot in 835 mm of annual rainfall, aluminum simply doesn't require maintenance. You don't reflash, re-caulk, or replace individual panels—no curling, cracking, or splitting to repair. Gutters still need seasonal cleaning, but the roof itself is inert. The Alunar coating is CALGreen-verified for reduced maintenance and warrants 30 years of color stability. A quick visual inspection every five years is all that's prudent; that's it.

Installation typically takes 2–4 days depending on home size and complexity. Yes, Interlock installs directly over existing asphalt or wood shingles (no tear-off required), which saves cost and time and keeps debris out of your yard. The lightweight profile—0.41 lb/sq ft for Slate—means minimal structural burden, so the existing deck stays in place. Your local Interlock installer, serving Racine County since 2001, will assess your roof's condition, nail the substrate, and lock the panels corner-to-corner. You avoid weeks of tear-off work, landfill charges, and the weather risk that comes with an exposed decking.

Aluminum is non-combustible—it cannot ignite—so Interlock qualifies for Class A fire classification, meeting ICC-ES ESR-1790 (the current IBC/IRC standard). Asphalt shingles are rated Class A too, but they melt and burn; aluminum simply doesn't participate in fire. It won't ignite from flying embers or radiant heat, which matters if wildfires ever approach Wisconsin's regions or if a neighboring property burns. The non-combustible rating also often qualifies you for homeowner's insurance credits in fire-prone areas. From a pure safety standpoint, there's no comparison—metal roofing is the non-combustible choice.

Yes. Sturtevant 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.
