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

Yes. Aluminum expands and contracts with temperature swings, but it does not crack, rot, or absorb moisture the way asphalt or wood does. Sun Valley experiences about 79 freeze-thaw days per year—intense cycling that destroys conventional materials. Interlock's 3105-H24 aluminum alloy was designed for exactly this stress. The oxide layer self-heals surface scratches, and the Alunar 70% PVDF coating remains flexible across temperature ranges. No warping, no splits, no seasonal degradation.

Metal roofing sheds snow far more effectively than asphalt. Sun Valley receives about 88 cm of snow annually plus 822 mm of rain. The smooth, interlocking aluminum panels—especially Slate and Tile profiles—slide snow and ice off rather than trapping moisture that causes ice dams and rot. The panels weigh 0.41 to 0.59 lb/sq ft depending on profile, so accumulated snow burden is minimal and no structural reinforcement is needed. You can add snow guards if desired, but the metal surface itself prevents the water seepage that plagues shingle roofs in freeze-thaw climates.

Aluminum cannot rust because it contains no iron. When exposed to air, aluminum instantly forms a self-healing oxide layer that protects the metal beneath—even if scratched during installation or maintenance. Steel roofs rust; aluminum does not. This is why Interlock panels are manufactured to ASTM B209 roofing-grade aluminum alloy (3105-H24 / 3003-H24). Add the Alunar 70% PVDF fluorocarbon coating—warranted 30 years against fading—and your roof is armored against Wisconsin's 822 mm annual rainfall and salt spray if near any road de-icing. This resistance is not a feature; it is the fundamental chemistry of the material.

Yes. Sun Valley's typical wind gusts reach 96 km/h; Interlock roofs are warranted to resist wind speeds up to 120 mph (193 km/h)—well above your local conditions. The four-way interlocking aluminum panels lock each sheet to its neighbors on all sides, distributing wind load across the entire roof plane rather than allowing individual shingles to lift or flutter. ICC-ES evaluation ESR-1790 confirms code compliance for high wind zones. This engineering means gusts that would tear asphalt shingles simply slide past your roof.

No reinforcement is needed. The Mediterranean Tile profile, which replaces 1,200+ lb/sq ft concrete or clay tile, weighs only about 0.59 lb/sq ft—roughly 96% lighter. Even the heavier Shake profile (0.58 lb/sq ft) weighs less than a typical asphalt roof over time when moisture saturation is factored in. This light weight lets Interlock install directly over most existing roofs, eliminating expensive structural upgrades. For Sun Valley homes with older framing, this is a real financial advantage. You get the luxury aesthetic without the load burden.

Interlock achieves UL 2218 Class 4 impact rating—the highest available. The warranty even covers perforation from hailstones up to 1.5 inches. Class 4 impact resistance often qualifies homeowners for insurance premium discounts because hail damage claims are virtually eliminated. Since Wisconsin's 88 cm annual snow can include hail within that moisture, this is not theoretical protection. Contact your insurer with the UL 2218 Class 4 certification; many carriers recognize it and apply immediate discounts. That reduction typically starts paying for itself within a few years.

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, giving the next owner 50 years from completion. Interlock has manufactured aluminum roofing since 1998 and installed panels from coastal salt-air homes to an Antarctic research station, with oldest installations still performing. In Sun Valley's climate of 3,128 sunshine hours annually and 79 freeze-thaw cycles, expect 50+ years of service—meaning this is the last roof you buy.

Aluminum metal roofing costs more upfront than asphalt but delivers lifetime value. Over a 50-year horizon, you will replace asphalt shingles 4–5 times (15–20 year lifespan each); labor, disposal, and material compound. Interlock's one-time installation, zero maintenance, and non-prorated lifetime warranty eliminate those cycles entirely. Your resale home retains the roof system intact—transferable to the next owner for another 50 years. Factor in potential insurance discounts (hail rating, non-combustibility) and energy savings (energy-efficient colors with up to 0.55 solar reflectance), and the payback window narrows significantly. For a permanent home investment, aluminum is the lower total cost.

Yes. energy-efficient Interlock colors have thermal emissivity of 0.84 and solar reflectance up to 0.55 (Aged Copper Penny profile), meaning they reflect heat that dark asphalt absorbs. Sun Valley receives about 3,128 sunshine hours per year. On warm days, reflective metal roofing reduces attic temperature gain compared to black or gray asphalt, lowering air conditioning load. The Cool Roof Rating Council rating confirms measurable energy benefit. Combined with the roof's zero maintenance and 30-year coating durability, you are trading higher initial cost for sustained energy efficiency across decades of Wisconsin summers.

Interlock Metal Roofing, the manufacturer's direct installer, has served this region since 2001. Your local team understands Sun Valley's climate profile—88 cm snow, 822 mm rain, 79 freeze-thaw days, and gusts to 96 km/h—and specifies the right profiles and fastening methods for your home. Factory training ensures ICC-ES ESR-1790 code-compliant installation. You work directly with the maker, not a third-party contractor, which means faster troubleshooting and accountability for every panel. When you call with questions about your roof, you are speaking with people who engineered it.

Yes. Sun Valley averages about 88 cm of snow, 822 mm of rain, roughly 79 freeze–thaw days a year, with peak wind gusts near 96 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.
