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

Interlock's four-way interlocking aluminum panels shed snow efficiently and resist the damage that freeze-thaw cycling causes to asphalt and wood. Jericho receives about 100 cm of snow annually and experiences roughly 76 freeze-thaw days per year—conditions that crack and curl traditional shingles. Aluminum panels expand and contract uniformly without splitting or curling; the oxide layer that forms on the aluminum surface actually self-heals from micro-scratches caused by ice movement. The lightweight design (Cedar Shingle at 0.41 lb/sq ft) minimizes structural stress from snow load, and the interlocking profile creates natural channels that manage water runoff even during rapid spring melt.

Aluminum cannot rust because it contains no iron—the element that oxidizes and corrodes. Instead, aluminum naturally forms a protective oxide layer that actually self-heals when scratched by ice, wind debris, or installation. Jericho's climate includes about 746 mm of annual rain and seasonal freeze-thaw stress, both of which accelerate corrosion in ferrous metals. Interlock panels use roofing-grade 3105-H24 and 3003-H24 aluminum alloy (ASTM B209), finished with Alunar 70% PVDF fluorocarbon coating on both sides for extra durability in wet, freeze-thaw environments. This combination means your roof won't develop rust spots, staining, or structural degradation from moisture exposure.

Most homes need no structural reinforcement because Interlock aluminum panels weigh significantly less than the slate or tile they replicate. The Mediterranean Tile profile installs at 0.59 lb/sq ft—approximately 96% lighter than clay or concrete tile—so it imposes minimal additional load on your framing. In comparison, traditional slate or tile roofing requires expensive structural upgrades before installation. Jericho's average wind gusts reach 108 km/h, yet Interlock's lightweight design combined with four-way interlocking actually improves wind resistance by distributing forces more evenly across the structure. Most existing roofs can simply receive the new metal panels directly over their current shingles or underlayment, reducing both labor cost and waste.

No. Interlock's four-way interlocking aluminum panels are warranted to resist wind speeds up to 120 mph (193 km/h) when installed to specification—well beyond Jericho's typical gusts of 108 km/h. The interlocking system creates mechanical bonds between adjacent panels so strong that they act as a unified membrane rather than individual shingles. Jericho experiences roughly 22 km/h mean daily winds with seasonal gusts, meaning this roof will far exceed the wind forces it encounters. The system's engineering has proven itself from coastal salt-air homes to Antarctica; multiple interlocks per seam distribute uplift forces across the entire roof plane, eliminating the weak points where traditional shingles separate or curl away from wind pressure.

Yes—Interlock achieves UL 2218 Class 4, the highest hail-impact rating available, and the Guardian Warranty even covers perforation from hailstones up to 1.5 inches. This certification reflects rigorous third-party testing against real-world impact scenarios. Some insurers offer premium reductions for Class 4 roofing because claims costs are statistically lower. Jericho's climate includes seasonal thunderstorms with hail risk, and submitting your Interlock documentation to your insurer may qualify you for a discount. The aluminum's non-combustible nature (Class A fire rating available) and superior impact resistance have made metal roofing increasingly recognized by underwriters. Contact your agent with the product's UL 2218 Class 4 rating and the warranty details to explore potential savings.

The Guardian Warranty is a lifetime limited, non-prorated material guarantee for the original owner—meaning there's no dollar-amount cap or percentage reduction over time. It covers rusting, rotting, splitting, cracking, curling, and loss of impact resistance, protecting you against the failures that force re-roofing. When you sell, the warranty becomes one-time transferable to the next owner for 50 years from project completion, adding measurable resale value. Interlock has manufactured these panels since 1998 in Delta, BC, with installations spanning from coastal salt-air environments to an Antarctic research station, validating durability across extreme climates. Jericho's 100 cm annual snow and 76 freeze-thaw days create the exact conditions where roofing materials are most stressed; this warranty's scope and transferability reflect Interlock's confidence in the product's longevity in such climates.

energy-efficient Interlock colors measurably reflect solar heat rather than absorbing it the way dark asphalt does. Aged Copper Penny and other cool-roof options achieve initial solar reflectance up to 0.55 and thermal emissivity of 0.84, both certified by the Cool Roof Rating Council. In Jericho, with about 3105 sunshine hours annually, summer cooling loads compound quickly; reflective coatings reduce the heat gain that drives air-conditioning runtime and cost. The Alunar 70% PVDF finish is warranted 30 years against fading and chalking (ASTM D4214/D2244), meaning the reflectance remains effective through decades of Wisconsin weather rather than degrading like asphalt. Combined with proper attic ventilation, a cool-roof metal roof can lower peak indoor temperatures measurably, particularly during sunny spring and autumn days when AC might otherwise cycle unnecessarily.

Interlock requires minimal maintenance—occasional gutter cleaning and debris removal—because aluminum panels don't develop the leaks, splits, or rot that plague asphalt and wood shakes. Asphalt shingles degrade under Jericho's 746 mm annual rainfall and intense UV exposure (3105 sunshine hours per year), requiring periodic repairs and eventual replacement. Wood shakes split, crack, and curl from freeze-thaw cycling (76 days per year in this region) and moisture infiltration. Aluminum doesn't split, curl, or rot; its coating is warranted 30 years against chalking and fading. There are no missing fasteners to replace, no moss or algae growth to pressure-wash away, and no seasonal inspections hunting for early failure signs. Gutters and downspouts need cleaning two or three times per year depending on leaf cover—the same maintenance any roof demands—but the roofing surface itself essentially maintains itself.

Interlock installs directly over most existing roofs without tear-off, typically completing residential projects in 3–7 days depending on roof size and complexity. The exceptional lightweight design—Cedar Shingle at 0.41 lb/sq ft, Shake at 0.58—eliminates the need for structural reinforcement or asphalt removal. Skipping the demolition phase saves labor cost, time, and the environmental impact of landfill-bound shingles. Your existing roof becomes an additional insulation layer and moisture barrier, enhancing thermal and acoustic performance. Interlock Metal Roofing has served Waukesha County since 2001 and manages the complete process: inspection, substrate preparation, panel installation, flashing, and final quality verification. Ice and snow removal from surrounding areas before installation ensures worker safety during Jericho's winter season and spring melt when moisture and freeze-thaw conditions peak.

Yes. Interlock aluminum panels are approximately 95% recyclable at end of life, breaking the asphalt industry's tear-off-to-landfill cycle. Every time an asphalt roof reaches failure, workers tear it off and discard it; a typical residential re-roofing generates several tons of waste destined for landfills. Interlock's 50+ year lifespan (often exceeding it) means one installation eliminates multiple future tear-offs over your ownership. When the roof does eventually require replacement decades away, aluminum retains material value and returns to the recycling stream intact, unlike asphalt's degraded petroleum binder. Jericho receives about 746 mm annual rain and 100 cm snow, both stressors that degrade asphalt rapidly; metal's non-degrading durability reduces the number of times waste and emissions occur over a century. CALGreen building standard recognizes Interlock roofing for reduced maintenance requirements and end-of-life recyclability—tangible environmental benefits beyond marketing claims.

Yes. Jericho averages about 100 cm of snow, 746 mm of rain, roughly 76 freeze–thaw days a year, with peak wind gusts near 108 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.
