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

Interlock metal roofing sheds snow and ice far more effectively than asphalt because its smooth, interlocked aluminum surface prevents ice dams from forming—water runs off rather than pooling under frozen layers. With Ourtown averaging about 105 cm of snow annually and 84 freeze-thaw days per year, this matters: the lightweight aluminum (Slate installs at 0.41 lb/sq ft) won't sag under repeated snow weight, and the four-way interlocking panels stay watertight even when ice expands. Optional snow guards can be installed if you want to control slide-off onto walkways. No ice dam damage, no premature wearing like you see in asphalt.

No. Aluminum's oxide layer self-heals when scratched, and the material itself doesn't absorb moisture, so freeze-thaw cycles can't crack it the way they crack wood shakes or cause asphalt to curl. Your region experiences roughly 84 freeze-thaw days per year—the coating (Alunar 70% PVDF, warranted 30 years) remains flexible across temperature swings, and the aluminum alloy (3105-H24 / 3003-H24 per ASTM B209) is engineered for this exact stress. Wood shakes split; asphalt curls; metal roofing stays intact. That's why we've installed these from coastal salt-air homes to an Antarctic research station.

Yes. Interlock roofing is warranted to resist wind speeds up to 120 mph when installed to specification—well above Ourtown's typical gusts of about 101 km/h recorded in your area. The four-way interlocking system locks each panel to its neighbors on all sides, creating a unified surface rather than individual shingles that can lift. A single panel isn't flying off in a spring squall. The ribs and overlap geometry also channel wind pressure around the roof rather than directly into it. Proper fastening (stainless steel per code ESR-1790) completes the picture. After 25+ years installing metal roofs here, wind damage isn't on our warranty claim list.

Interlock aluminum roofing carries a UL 2218 Class 4 impact rating—the highest available—and the warranty even covers perforation from hailstones up to 1.5 inches. The light weight (Shake at 0.58 lb/sq ft) and rigidity of interlocked aluminum absorb impact energy without denting permanently. Many insurers recognize this and offer premium discounts for Class 4 roofing; contact your agent with the UL listing (Intertek 33876) to ask about a reduction. Asphalt shingles don't carry Class 4 ratings. Over a 50-year roof life, the insurance savings alone can offset a meaningful portion of the material cost.

No structural reinforcement is needed. Interlock Mediterranean Tile installs at approximately 0.59 lb/sq ft—about 96% lighter than concrete or clay tile—so most existing roofs can support it without modification. Concrete tile weighs 10–15 times more and requires framing upgrades. Our aluminum tile replicates the aesthetic without the structural cost. The material can install directly over your existing asphalt shingles in many cases (saving tear-off labor), and the four-way interlocking system distributes load evenly. A structural engineer can confirm your specific home's capacity, but in our 25 years serving this region, we rarely encounter a roof that can't support Interlock aluminum.

The Guardian is a lifetime limited, non-prorated material warranty for the original owner—covering rust, rot, splitting, cracking, curling, and loss of impact resistance. It's one-time transferable, giving the next owner 50 years from completion. No other roofing material offers this: asphalt shingles come with 20–25 year prorated warranties that decline yearly; wood shakes split and require replacement within 25–30 years; tile cracks from impact. Interlock's aluminum alloy (3105-H24 / 3003-H24) doesn't degrade the way those materials do. Combined with the 30-year coating warranty on the Alunar fluorocarbon finish, you're looking at a roof that outlasts the house—and adds resale appeal because the next owner inherits 50 years of coverage.

Yes. energy-efficient colors reflect heat rather than absorbing it—our Aged Copper Penny achieves initial solar reflectance up to 0.55 and thermal emissivity of 0.84, rated by the Cool Roof Rating Council. This matters in Ourtown, where you get about 3113 sunshine hours annually: reflective coatings keep roof surface temperature cooler, reducing heat transfer into attic and living spaces. Dark asphalt absorbs solar energy and re-radiates it into your home. Metal roofing with high solar reflectance can cut cooling loads by 10–20%, translating to lower summer utility bills. The effect is modest in Wisconsin's climate compared to Arizona, but over 50 years, the cumulative savings add up—especially if air conditioning is running during humid July and August.

Virtually none. Aluminum doesn't rot, split, or curl like wood shake or asphalt shingles. It requires no treatment, sealing, or replacement of individual pieces. Gutters should be cleaned yearly (true for any roof), and moss can be rinsed off in shaded areas, but that's standard homeowner upkeep. Asphalt shingles require nail-down repairs, missing shingle replacement, and granule loss inspection every 3–5 years. Wood shake demands professional treatment and periodic re-nailing. Interlock's CALGreen verification confirms reduced maintenance burden. Over a 50-year lifespan, the time and cost you don't spend on repairs pay for the material upgrade—plus you avoid hiring roofers in winter when Wisconsin weather makes work dangerous and expensive.

Installation typically takes 3–7 days depending on home size and complexity; a typical Ourtown residence installs in 5 days. Yes, Interlock aluminum can install over most existing asphalt roofs without tear-off, which saves weeks of debris removal and landfill costs while preserving the old roof as additional underlayment. Our local team (serving the region since 2001) walks you through the process: we secure underlayment, snap chalk lines, start at the eave, and interlock panels row by row—each panel locks to the last. The four-way interlocking system means no shingling nails, no overlaps to align shingle-by-shingle, no slack. Faster installation also means lower labor costs. We'll inspect your roof structure beforehand and tell you upfront whether tear-off is required (rare) or overlay is safe.

Yes, over the roof's life. Asphalt costs $8,000–$12,000 installed and lasts 20–25 years before re-roofing; that's two or three replacements per 50-year building lifespan. Metal roofing costs more upfront ($20,000–$30,000 for a typical home) but lasts 50+ years under the Guardian warranty. You buy the roof once, not twice. Add avoided labor costs (no maintenance repairs, no gutter cleaning from granule washoff), avoided insurance claims (Class 4 hail protection), potential insurance discounts, energy savings from reflective coatings, and zero landfill tear-offs, and the total cost of ownership favors metal decisively. Over 50 years, metal costs less per year than asphalt—and you transfer 50 years of coverage to the next owner, which increases resale value more than the initial investment.

Yes. Ourtown averages about 105 cm of snow, 726 mm of rain, roughly 84 freeze–thaw days a year, with peak wind gusts near 101 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.
