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

Interlock metal roofing sheds snow and ice far better than asphalt because its smooth, hard surface prevents the grip that causes ice dams. With about 88 cm of snow falling annually in Wauwatosa and roughly 79 freeze-thaw cycles per year, your roof faces real risk of trapped water damage — but aluminum's slick finish keeps snow moving. Add optional snow guards if you want to control where it slides, and you've eliminated one of the costliest winter roof problems.

No. Aluminum expands and contracts freely without cracking because it has no grain structure like wood or brittleness like asphalt. Wauwatosa experiences roughly 79 freeze-thaw days yearly plus 822 mm of rain, creating constant material stress — but roofing-grade 3105-H24 aluminum simply flexes and recovers. The Alunar 70% PVDF coating on both sides stays bonded through this cycling, backed by a 30-year fade and chalking warranty so you never see deterioration.

Aluminum cannot rust because it contains no iron — only aluminum oxide, a protective layer that heals itself when scratched. While steel roofs corrode in Wauwatosa's moist 822 mm annual rainfall, aluminum grows stronger over time. The Alunar coating (applied to both panel sides) adds a 30-year warranty against corrosion, so even salt-air installations outlast uncoated steel by decades. You get genuine material permanence, not just a coating promise.

Interlock metal roofing is extraordinarily light — the Mediterranean Tile profile weighs just 0.59 lb/sq ft, roughly 96% lighter than concrete or clay tile. This means no roof truss upgrades, no engineer, no months of planning. Most homes can install it directly over existing asphalt, cutting labor time and cost. Wauwatosa homeowners benefit immediately: faster installation, lower structural load through Wisconsin winters with about 88 cm of snow, and the peace of mind that your home's bones stay untouched.

Interlock's four-way interlocking aluminum panels are warranted to resist sustained winds up to 120 mph, well above Wauwatosa's typical gust speeds of roughly 96 km/h. The overlapping seam design transfers load across the entire roof plane rather than loading individual fasteners, so wind can't peel or lift panels. You're protected not just in routine weather but in rare severe events — with warranty coverage that proves the engineering.

Interlock earns UL 2218 Class 4 impact rating, the highest available, and the warranty even covers perforation from hailstones up to 1.5 inches. This non-combustible aluminum construction often qualifies you for homeowners insurance discounts — talk to your carrier about aluminum metal roofing credits. In Wauwatosa, where severe weather can strike any season, Class 4 impact resistance plus a damage-backed warranty means real financial protection and potentially lower premiums.

The Guardian Warranty is a lifetime limited, non-prorated material warranty for the original owner — it covers rusting, rotting, splitting, cracking, curling, and loss of impact resistance. Transfer it to the next owner, and they receive 50 years of coverage from completion. For a Wauwatosa homeowner, this is the last roof you'll install in your home, and it's an asset you can pass on with confidence.

Interlock metal roofing requires virtually no maintenance — no annual inspections, no repairs to loose granules, no treatment for moss or algae. Asphalt shingles degrade under Wauwatosa's intense freeze-thaw cycling (about 79 days yearly) and demand regular attention. Aluminum simply sheds debris with rain (about 822 mm annually) and keeps its Alunar coating intact for 30 years. You reclaim weekends and budget once it's installed.

Interlock's energy-efficient colors achieve up to 0.55 initial solar reflectance and 0.84 thermal emissivity, reflecting heat that asphalt absorbs. Wauwatosa receives roughly 3128 sunshine hours per year — enough that reflective roofing measurably reduces air-conditioning load in summer. The Cool Roof Rating Council rating backs this performance. Combined with Wisconsin's moderate summers, the energy savings may seem modest, but over 50+ years they compound into real utility relief.

Yes. Interlock aluminum is approximately 95% recyclable, so at end of life your roof returns to the aluminum supply chain. Asphalt shingles, by contrast, end the tear-off-to-landfill cycle — millions of tons yearly. Wauwatosa homeowners who choose aluminum avoid contributing to that waste stream and support genuine circular material reuse. The manufacturing process in Delta, BC has been running since 1998 with consistent sustainability metrics, and the roof itself outlasts asphalt by decades, so you buy far fewer replacements over a lifetime.

Yes. Wauwatosa 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.
