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

Metal roofs shed snow and ice far more effectively than asphalt shingles because aluminum's smooth surface prevents adhesion and reduces ice dam formation. Glendale receives about 88 cm of snow annually and experiences roughly 79 freeze-thaw cycles each year, the exact conditions that crack and curl asphalt shingles but leave aluminum unaffected. The four-way interlocking panels lock together tightly, and snow guards can be added to control shedding if desired. You get a roof that handles winter stress without degrading.

No. Aluminum expands and contracts with temperature swings, but it doesn't absorb water, so freeze-thaw cycling cannot crack, rot, or split it the way it does asphalt or wood shakes. Glendale's 79 annual freeze-thaw days are exactly where material brittleness shows up—and that's precisely why aluminum's flex and moisture immunity matter here. The roofing-grade 3105-H24 alloy is engineered for thermal stress, and the non-prorated lifetime warranty covers cracking and splitting, giving you confidence that winter won't degrade your roof.

Aluminum cannot rust because it contains no iron; instead, it forms a self-healing oxide layer that actually protects the underlying metal. When scratched or exposed, this barrier repairs itself—a property no steel roof can match. Glendale's 822 mm of annual rainfall and humid Great Lakes-adjacent climate mean corrosion resistance is a real asset. The Alunar 70% PVDF fluorocarbon finish (applied to both sides) adds 30 years of fade and chalk protection under ASTM D4214 testing, so your roof stays protected through decades of Wisconsin weather.

Yes. The four-way interlocking design and proper installation warrant resistance to wind speeds up to 120 mph, well above Glendale's typical gusts of about 96 km/h recorded in the region. The panels lock together on all four edges, creating a unified surface that resists uplift and lateral forces that tear apart standard shingles. Wisconsin's exposure to Lake Michigan weather systems makes wind durability essential, and this interlocking system was designed for exactly those conditions. You're protected far beyond the wind speeds your area typically experiences.

Interlock Metal Roofing achieves UL 2218 Class 4 impact rating—the highest available—and the warranty even covers perforation from hailstones up to 1.5 inches. Many insurers recognize this rating and offer premium reductions on homes with Class 4-rated roofs. Glendale's weather history includes severe thunderstorms capable of producing hail, so this protection is practical, not theoretical. The impact resistance doesn't degrade over time, meaning your hail protection lasts the life of the roof. Check with your insurance agent about discounts once installation is complete.

No. Interlock's Slate profile installs at 0.41 lb/sq ft, Cedar Shingle at 0.58, and even the Mediterranean Tile at 0.59—about 96% lighter than concrete or clay tile. This extraordinary lightness means no structural reinforcement is needed, and the roof installs directly over most existing asphalt shingles without adding stress. A concrete tile roof weighs roughly 15 lb/sq ft, so you're comparing feather-light aluminum to material that demands engineered support. That's why Interlock installs from coastal homes to Antarctic research stations without framing upgrades.

When you measure total cost over the roof's life, aluminum is often the last roof you buy. Asphalt shingles last 15–25 years and end in a landfill; Interlock's non-prorated lifetime limited warranty covers the original owner forever and transfers once to the next owner for 50 years from completion. Over three decades, you avoid tear-off labor, disposal fees, and replacement. Glendale's 79 annual freeze-thaw days and 88 cm of snow accelerate asphalt failure, making that shorter lifespan even costlier. When you calculate avoided replacement cycles, the upfront premium shrinks significantly.

The Guardian Warranty is a lifetime limited, non-prorated material warranty for you as the original owner, covering rusting, rotting, splitting, cracking, curling, and loss of impact resistance—the six ways roofs fail. It transfers once to the next owner for a 50-year term from project completion, adding resale value. No prorating means you're covered equally in year one and year 30. Most roofs fail from the problems listed above, and having zero-dollar coverage for the roof's life—and partial coverage for the next owner—eliminates the financial surprise that defines asphalt ownership.

Yes. Interlock's featherweight design (0.41–0.59 lb/sq ft) and interlocking panels install directly over existing roofs in most cases, eliminating expensive tear-off and disposal. Installation is faster than traditional shingles because panels cover more area per fastener, and the process typically completes in days rather than weeks. Local installer Interlock Metal Roofing has served the region since 2001 and understands Glendale's conditions and building requirements. Over-roof installation also adds an insulation layer, improving energy performance. Your existing structure and budget both benefit.

Interlock Metal Roofing requires virtually no maintenance—no moss treatment, no shingle replacement, no sealant reapplication. Asphalt shingles demand routine inspection, tar adhesive fails in freeze-thaw cycles, and wood shakes invite rot and pest damage in Glendale's 822 mm of annual rainfall. Concrete and clay tiles crack in freeze-thaw stress and require mortar repointing. Aluminum's oxide layer self-heals, the interlocking panels shed water without pooling, and the 30-year Alunar coating warranty means no refinishing. CALGreen verification confirms reduced maintenance liability, lowering your long-term ownership costs and effort.

Yes. Glendale 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.
