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

Yes. Aluminum cannot rust because it contains no iron—its oxide layer self-heals when scratched, so repeated freeze-thaw cycling (Wind Point averages 79 days per year) won't degrade the material. The Alunar 70% PVDF coating is warranted 30 years against chalking and fading under ASTM D4214 testing, which includes thermal-shock cycles. Asphalt and wood shingles absorb moisture, crack, and curl during freeze-thaw; aluminum's non-porous surface sheds water immediately.

Metal roofing handles heavy snow exceptionally well. Wind Point receives about 88 cm of snow annually, but the real advantage is weight: Interlock's Slate profile installs at just 0.41 lb/sq ft—so light that no structural reinforcement is needed, and snow doesn't crush the roof like it can with slate or tile. The four-way interlocking panels prevent snow and ice from sliding dangerously. Snow guards can be added if desired. The smooth, hard surface sheds moisture instead of absorbing it, so ice dams are far less likely to form.

Yes. Wind Point experiences typical gusts up to 96 km/h, and Interlock's four-way interlocking aluminum panels are warranted to resist wind speeds up to 120 mph (193 km/h) when installed to specification. The ICC-ES ESR-1790 evaluation confirms the system meets IBC/IRC wind load requirements. Unlike loose shingles, the panels interlock and transfer wind loads across the entire roof plane rather than relying on fasteners or adhesive alone. Installation must follow the spec—Interlock's local team has been serving this region since 2001.

No. Interlock's Mediterranean Tile profile weighs only about 0.59 lb/sq ft—roughly 96% lighter than concrete or clay tile—so most existing roof structures need no reinforcement. Even the heavier Shake profile at 0.58 lb/sq ft is negligible compared to real tile. This light weight makes retrofit installation practical: Interlock installs directly over your existing asphalt shingles in most cases, saving the cost and landfill impact of tear-off. Your home's frame won't feel additional structural strain.

Interlock achieves UL 2218 Class 4 impact rating—the highest available—and the Guardian warranty covers perforation from hailstones up to 1.5 inches. Most Wisconsin insurers offer discounts for Class 4 roofing because the claim history is excellent. Wind Point's hail risk is moderate, but the non-combustible aluminum (Class A fire rating available) and extreme durability often qualify you for lower premiums than asphalt. Contact your insurer with the UL 2218 Class 4 rating and ICC-ES ESR-1790 documentation to discuss your discount.

Aluminum cannot rust because it contains no iron. A protective oxide layer forms naturally and self-heals when scratched, so even Wind Point's 822 mm annual rainfall and 88 cm snow won't corrode the material. The Alunar 70% PVDF fluorocarbon coating (applied to both sides of each panel) adds another 30-year warranty against salt air and atmospheric degradation. Steel roofing rusts from the inside out once fasteners and seams fail; aluminum roofing simply gets lighter and more durable with age. This matters in humid climates near water.

Very little. Asphalt requires regular inspection, nail replacement, and sealant reapplication; wood shingles need annual cleaning and moss treatment; tile needs regrouting. Interlock's non-porous aluminum surface won't rot, split, curl, or support moss growth. Wind Point's 3128 annual sunshine hours keep the roof dry. Occasional debris removal and gutter cleaning are all that's needed—the roof itself requires no maintenance. The Guardian warranty covers loss of impact resistance, so you're protected against degradation that would otherwise demand costly repairs.

Yes, over the roof's life. A typical asphalt roof lasts 15–20 years in Wisconsin's freeze-thaw climate and must be replaced twice during Interlock's lifetime. The Guardian warranty is non-prorated for the original owner (and one-time transferable to the next owner for 50 years), so you won't pay for declining coverage as years pass. Eliminate two tear-offs, disposal fees, labor, and re-roofing downtime. Interlock's light weight often avoids structural upgrades that slate or tile would require. The material cost difference shrinks when you count total cycles over 40+ years.

Yes. Interlock's aluminum is approximately 95% recyclable at end of life, versus asphalt shingles that end up in landfills by the millions of tons yearly. You also avoid the tear-off cycle: replacing an asphalt roof twice over 40 years means two rounds of removal, debris hauling, and landfill impact. Interlock installs over existing roofs, cutting waste immediately. The material's durability means fewer mining and manufacturing cycles. CALGreen verification confirms reduced maintenance burden. Aluminum recycling requires far less energy than primary smelting, and your roof can return to the supply chain indefinitely.

Installation typically takes 2–5 days depending on roof complexity and square footage. Unlike asphalt, Interlock often installs directly over your existing shingles, eliminating 1–2 days of tear-off work and disposal. The four-way interlocking panels speed fastening and prevent the rework that loose shingles demand. Weather delays matter less because aluminum won't absorb moisture like wood or asphalt. Interlock's local team has served the Wind Point region since 2001 and can schedule your project around your timeline. A quick installation minimizes disruption to your home and family.

Yes. Wind Point 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.
