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

Metal roofs shed snow faster than asphalt because the smooth, hard surface and thermal properties don't trap moisture the way shingles do. Burr Oaks receives about 89 cm of snow annually across roughly 84 freeze-thaw days, which means your roof cycles between frozen and thawing constantly. Interlock's lightweight aluminum panels (the Slate installs at just 0.41 lb/sq ft) won't accumulate ice weight like traditional tile would, and the four-way interlocking design prevents water infiltration during those thaw cycles. Snow guards are available if you want to manage sheet slides.

No—aluminum actually thrives through freeze-thaw. The material expands and contracts uniformly, and it contains no iron, so it cannot rust even when exposed to moisture and salt spray during freeze cycles. With Burr Oaks averaging 84 freeze-thaw days yearly, this durability matters. The four-way interlocking panels accommodate movement without cracking or curling. The Alunar fluorocarbon coating (30-year warranty, ASTM D4214 rated) remains intact through thousands of these cycles, protecting the substrate underneath indefinitely.

Aluminum cannot rust because it contains no iron—the element that corrodes. Instead, aluminum forms a self-healing oxide layer when exposed to air and moisture, which actually protects the metal underneath. Burr Oaks gets about 781 mm of rain annually, so wetness is constant, but that's precisely where aluminum excels. The Alunar coating (applied to both sides of every panel) adds a second barrier with its 30-year fade/chalk warranty. This two-layer protection is why Interlock panels are installed from coastal salt-air homes to Antarctic research stations.

Interlock's four-way interlocking system is engineered to resist wind speeds up to 120 mph when installed per spec—well above Burr Oaks' typical gust patterns of around 104 km/h (about 65 mph). Each panel locks on all four sides, creating a unified assembly that prevents lifting or separation during storms. The ICC-ES evaluation report ESR-1790 confirms the design for residential wind loads. In a climate where gusts regularly test roofing, this interlocking grip gives you certainty that fasteners and seams won't fail.

UL 2218 Class 4 impact rating—the highest available—means Interlock withstands hailstones up to 1.5 inches without perforation, and the Guardian Warranty covers perforation at that threshold. This rating may qualify you for homeowner's insurance discounts because the roof material itself reduces claim frequency. In Wisconsin, hail risk is real, especially spring and early summer. Ask your insurer about premium reductions; many carriers recognize Class 4 aluminum as a low-risk material. The combination of light weight, impact resistance, and long lifespan often makes the insurance math work in your favor.

Yes, without structural reinforcement. The Interlock Slate profile weighs just 0.41 lb/sq ft, the Shake about 0.58 lb/sq ft, and even the Mediterranean Tile is roughly 96% lighter than concrete or clay tile. This means you can install over existing asphalt without burdening your home's framing. Burr Oaks' climate includes heavy snow (about 89 cm yearly), but the roof's own weight is negligible compared to that snow load—your structure handles the snow, not the roofing material. Overlay installation saves weeks of tear-off work and keeps asphalt out of landfills.

Metal roofing costs more initially but becomes the last roof you install. Asphalt typically lasts 15–20 years in Wisconsin's 84 freeze-thaw-day climate and heavy snow, requiring replacement, tear-off, and landfill disposal multiple times over a lifetime. Interlock carries a lifetime limited, non-prorated material warranty for the original owner (one-time transferable to the next owner for 50 years). Over 50 years, one aluminum roof replaces 2–3 asphalt roofs. You avoid repeated labor, disposal fees, and home disruption. The durability math favors metal.

energy-efficient colors reflect heat instead of absorbing it like dark asphalt does. Interlock's Aged Copper Penny achieves initial solar reflectance up to 0.55 and thermal emissivity of 0.84, both verified by the Cool Roof Rating Council. While Burr Oaks' climate is cool (mean 9.1°C annually), the 3089 annual sunshine hours still deliver summer heat that a reflective roof deflects rather than trapping. Over the course of a cooling season, this reduces air-conditioner runtime. The energy savings are modest in Wisconsin's cooler profile but measurable, especially during hot spells.

Interlock Metal Roofing has served the region since 2001 and is the authorized installer for Burr Oaks and the surrounding area. They understand Dane County's snow load, freeze-thaw patterns, and local building codes. When you choose Interlock, you're working with installers experienced in Wisconsin winters and the four-way panel interlocking system that makes performance possible. They handle permitting, inspections, and warranty registration. Your roof's longevity depends on correct installation; local expertise matters.

Aluminum is non-combustible, and Interlock offers Class A fire classification—the highest rating available. This means the roof material itself does not ignite or spread flame, regardless of external fire exposure. While Burr Oaks is not in a wildfire zone, Class A rating can lower insurance premiums and satisfies stringent building codes. The ICC-ES evaluation report ESR-1790 confirms the fire rating. Depending on your home's location and exposure, a non-combustible roof may also be a requirement. It's another layer of long-term safety.

Yes. Burr Oaks averages about 89 cm of snow, 781 mm of rain, roughly 84 freeze–thaw days a year, with peak wind gusts near 104 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.
