Metal Roofing Built for St. Joseph’s's Heavy Rain, Snow Loads, Windstorms & Lifetime Protection

Performance you can measure (all climates):
• Authorized Interlock® installer serving homeowners in St. Joseph’s and nearby Milwaukee County.
• Precision weatherproof seams (profiles: slate, cedar, shake, tile) and mechanical fastening (profile: standing seam) deliver long-term leak protection during wind-driven rain events.
• Aluminum panels finished with the Alunar® Coating System (no visible aluminum surface) for durable, fade-resistant color through St. Joseph’s seasonal sun and storms.
• Tested to 193+ km/h (120+ mph) for wind resistance to help withstand severe gusts and derecho-driven winds that can affect southeast Wisconsin.
• Designed to shed heavy Lake Michigan–influenced snow and reduce ice-dam formation during the frequent freeze–thaw cycles of St. Joseph’s winters.
• Corrosion-resistant construction addresses elevated exposure to winter road salts and persistent humidity found around Milwaukee County shorelines.
• Class A fire-rated available for added protection where structure fires or ember exposure is a concern.
• UL 2218 Class 4 impact resistance for protection from hail, falling branches, and storm debris common in Midwest storms.
• Energy-efficient cool-roof performance to moderate attic temperatures during Midwest heat waves and improve long-term HVAC efficiency.
• Solar-compatible design engineered for modern bracket-mounted photovoltaic systems typical on St. Joseph’s residential roofs.
• Low-maintenance finish and recyclable aluminum help St. Joseph’s homeowners reduce lifecycle costs and environmental footprint.
• Lifetime-Limited transferable warranty provides clear, documented protection that supports resale value in the St. Joseph’s market.
• Atmospheric-river resilience: robust seam and fastening design improves leak resistance during occasional extreme precipitation events that bring sustained heavy rain to the region.
• Coastal salt-air consideration: Alunar® finish and aluminum substrates resist corrosion where Lake Michigan shoreline exposure and road-salt drift affect roofs near St. Joseph’s.
• Moss-inhibiting finishes and smooth panel profiles reduce moss and algae adhesion on shaded, moisture-prone roofs around St. Joseph’s.

Interlock® Aluminum Roofing — all-climates performance specs for St. Joseph’s, Wisconsin
| Spec / Rating | Climate / Risk Factor + What It Solves |
|---|---|
| Wind resistance: 120+ mph (193+ kph) | Extreme wind, hurricanes, storm uplift: full interlocking attachment helps prevent blow-offs, edge lifting, and panel loss in high-gust events. |
| Fire rating: Class A (with proper assembly) | Wildfire, embers, radiant heat, chimney sparks: non-combustible roof assembly provides the highest residential fire protection rating. |
| Hail resistance: UL 2218 Class 4 | Hail and impact debris: highest impact classification; resists cracking, splitting, and surface loss common with asphalt under hail strikes. |
| Snow & ice performance: interlocking, shedding profile | Heavy snow, freeze-thaw, ice dams: smooth aluminum sheds snow efficiently and the interlocking design helps block water intrusion when melt-refreeze cycles occur. (Final snow-load capacity depends on roof structure and local code.) |
| Corrosion resistance: aluminum (won’t rust) | Salt air, coastal humidity, wet climates: aluminum naturally resists rust and corrosion, reducing long-term failure risk in marine or high-moisture environments. |
| Heat / UV durability: baked-on coating system | High heat, intense sun, thermal cycling: coatings resist UV breakdown and temperature-swing fatigue, slowing fading and surface degradation. |
| Moss / algae resistance: smooth coated surface | Wet shade, organic growth: low-porosity metal surface gives moss/algae less to grip, reducing staining and maintenance. |
| Material: heavy-gauge aluminum roof profiles (Slate / Shake / Shingle / Tile / Standing Seam) | All-season structural stability: lightweight, dent-resistant metal system stays stable through large hot-cold swings and severe weather. (Add exact alloy + thickness for maximum spec proof.) |
| Expected lifespan: 50+ years | Long-term durability across climates: avoids re-roof cycles typical of shorter-life materials, even in high-stress environments. |
| Warranty: Lifetime-Limited, non-prorated + 50-year transferable | Lifetime protection + resale value: guarantees long-term material confidence and transfers to future owners. |
