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

Yes. Interlock aluminum roofing is engineered to withstand repeated freeze-thaw stress without cracking, splitting, or losing integrity. Burlington experiences roughly 83 freeze-thaw days per year, where moisture enters material cracks and expands when it freezes. Aluminum's non-porous oxide layer and homogeneous alloy structure (ASTM B209 3105-H24) mean water cannot penetrate and expand inside the material the way it does in asphalt, wood, or clay. The four-way interlocking seam design prevents water from pooling between freeze cycles. This material durability is why Interlock's Guardian Warranty explicitly covers cracking and splitting—conditions that plague traditional roofing in climates like yours.

Metal roofing sheds snow and ice far more effectively than asphalt because its smooth, hard surface prevents adhesion and allows gravity to do the work. Burlington receives about 84 cm of snow annually, and the slick aluminum finish resists the ice-dam formation that traps water on traditional roofs. The four-way interlocking panels are warranted to 120 mph wind speeds, which handles gusts up to 100 km/h common in your region—snow and ice sheets that might shift in high wind stay locked in place. Snow guards are optional and available if you prefer to retain snow for aesthetic reasons. The lightweight design (Standing Seam at ~0.41 lb/sq ft) means your structure handles seasonal accumulation without strain, and the coating's 30-year fade and chalk warranty means winter salt spray and UV reflection off snow won't degrade the finish.

Aluminum cannot rust because it contains no iron—the element that oxidizes and causes rust in steel roofing. Instead, aluminum forms a self-healing oxide layer that protects the substrate from moisture and salt air. When scratched, this oxide layer regenerates within hours, sealing the breach automatically. Burlington's 838 mm of annual rainfall and freeze-thaw cycling create persistent moisture exposure, yet the material remains impervious. The Alunar 70% PVDF fluorocarbon finish (applied to both sides) adds a 30-year warranty against chalking and fading, protecting even the underside of panels in salt-air or humid conditions. This is why Interlock installs from coastal salt-air homes to Antarctic research stations—aluminum's corrosion resistance is absolute, not conditional.

No. Interlock metal roofing panels are four-way interlocking and warranted to resist wind speeds up to 120 mph when installed to specification. This covers the gusts up to 100 km/h recorded in Burlington during seasonal storms, with a safety margin. The interlocking seam design means wind cannot peel or lift individual panels—all four edges are engaged mechanically before the next panel overlaps. This same engineering prevents wind-driven rain from entering gaps, protecting against the persistent 838 mm of annual rainfall your region receives. The design also resists the upward pressure that can occur when wind passes beneath lifted eaves. Insurance companies recognize this durability; check with your agent about potential discounts tied to the UL 2218 Class 4 hail and impact rating.

No structural reinforcement is needed. Interlock's Mediterranean Tile profile weighs only ~0.59 lb/sq ft—roughly 96% lighter than concrete or clay tile—and Slate is similarly minimal. This means the roof installs over most existing structures without expensive beam reinforcement that would be required for traditional tile. Concrete or clay tile typically weighs 10–15 lb/sq ft, straining older homes throughout Racine County that weren't built to support that load. Interlock's lightweight aluminum alloy (ASTM B209) eliminates this constraint entirely. The panels install directly over existing asphalt roofing, saving tear-off labor and disposal costs. Your home's framing handles the load the same way it handles current roofing, so budget goes toward longevity and aesthetics, not structural work. The Guardian Warranty includes the material indefinitely, giving you true confidence in a lightweight, transferable investment.

Yes, over the roof's full life cycle. Asphalt shingles typically last 15–25 years in Wisconsin's climate; you'll replace them twice or three times in a normal household lifespan. Each replacement means labor, tear-off disposal to landfill, and years of vulnerability between jobs. Interlock's Guardian Warranty is lifetime limited for the original owner and transferable for 50 years to the next owner—covering rusting, rotting, splitting, cracking, curling, and loss of impact resistance. The coating is warrantied 30 years against chalking and fading (ASTM D4214 tested). With roughly 3,084 sunshine hours, 838 mm rain, and 83 freeze-thaw cycles per year in Burlington, asphalt degrades faster than in milder zones. Metal roofing is the last roof you buy; the transferable warranty also increases resale appeal, offsetting the material premium over a 30–50-year horizon.

Yes. Interlock offers Class A fire classification on all profiles because aluminum is non-combustible—it contains no fuel to ignite and does not spread flame. This meets the highest fire safety standard (ASTM E136, IBC/IRC via ICC-ES evaluation report ESR-1790, reissued 2025). Many homeowners in Racine County are surprised that metal roofing is not just fire-resistant but impossible to ignite, even when embers from nearby wildfire or chimney spark land on it. The non-combustible rating also qualifies for CALGreen-verified low-maintenance credits and can lower insurance premiums in some cases. If your home is in a fire-prone zone or you simply want to eliminate one major risk, Class A non-combustibility is a genuine safety upgrade that asphalt cannot match. Check with your agent about potential insurance savings tied to the fire classification.

Minimal maintenance. Aluminum requires only occasional visual inspection and gutter cleaning—no annual sealant reapplication, no protective coatings, no wood staining or fungicide treatment like cedar shake demands. With 838 mm of annual rainfall, your gutters will fill, but the roof itself is inert. Asphalt roofs require regular moss and debris removal in wet climates; wood roofing requires stain, sealant, and fungicide every 3–5 years. Interlock's solid-lock seam design and CALGreen-verified low-maintenance status mean you avoid the ongoing labor and chemical expense that traditional materials impose. The Alunar 70% PVDF finish is self-cleaning in Burlington's frequent rain—dirt and salt spray rinse away without intervention. Over 50 years, the cumulative cost of asphalt tar coatings, wood treatments, and professional moss removal adds up to thousands; metal roofing eliminates these entirely, making your home more passive and your budget more predictable.

Yes. Interlock aluminum roofing is approximately 95% recyclable, and aluminum recycles infinitely without loss of properties—a closed-loop cycle that asphalt cannot match. Every time you replace asphalt shingles in Wisconsin, the old material ends up in landfill (or burned, releasing fumes). Over 50 years, a typical home generates 2–3 asphalt roof tear-offs. Interlock's lifetime warranty and transferable 50-year term mean you install once and your heirs inherit a roof that doesn't need replacement. The manufacturing process in Delta, BC, uses energy efficiently to produce roofing-grade aluminum alloy (ASTM B209), and the end-of-life material has value—scrap aluminum markets exist worldwide. With 3,084 sunshine hours annually in Burlington, the energy-efficiency reflective coatings (aged solar reflectance up to 0.55) also reduce cooling load, lowering your home's lifetime carbon footprint. Metal roofing ends the asphalt tear-off-to-landfill cycle and closes the loop.

Yes, in most cases. The ultra-lightweight Interlock panels (Mediterranean Tile ~0.59 lb/sq ft, Slate similar) install directly over asphalt shingles, eliminating costly tear-off labor and landfill fees. Your roofer inspects the existing roof for structural integrity and proper drainage; if sound, the new panels attach over it. The process is faster than full removal because no debris disposal is required and no weather delays from tear-off stages. In Burlington's wet climate (838 mm rain, 83 freeze-thaw days per year), leaving the existing roof in place provides an extra vapor barrier. Interlock Metal Roofing, serving the region since 2001, can assess your roof onsite and confirm whether an overlay is viable. The resulting profile—say, Standing Seam or Shake—looks and performs like new architecture while your existing roof remains as underlayment. This approach combines cost savings with the durability of the Guardian Warranty.
