Top 7 Metal Roofing Types for Minnesota and Wisconsin Homes

Roofing in the Upper Midwest faces extremes: quarter‑size hail in summer, heavy snow loads in winter, and freeze‑thaw cycles that degrade asphalt shingles. Metal roofs excel under these conditions, lasting 50–80 years if installed correctly. While upfront prices run higher, metal roofing often outperforms traditional materials in lifespan, energy savings, and insurance benefits. This guide explores seven metal roofing types, breaking down how each system works, typical installed costs, key advantages and drawbacks, and what you’ll spend on maintenance over decades.

Why Choose Metal Roofing in Minnesota and Wisconsin

 

• Longevity & Life‑Cycle Savings: Asphalt roofs last 15–20 years. Metal roofs often exceed 50 years, reducing total replacement cycles and saving 20–30% over 50 years.
• Hail & Wind Resistance: Class 4 impact ratings and wind uplift tests up to 140 mph protect homes from severe weather, cutting repair costs and insurance claims.
• Energy Efficiency: Reflective coatings lower attic temperatures by up to 30%, trimming cooling bills by $150–$300 annually.
• Insurance Discounts & Resale Value: Many insurers offer 5–15% premium reductions for metal roofs. Homes with metal roofs may sell faster and for higher prices.
• Environmental Impact: With 30–60% recycled content and full recyclability, metal roofs minimize landfill waste from torn‑off shingles.

Top Metal Roofing Styles

Below are the top seven metal roofing systems available to Minnesota and Wisconsin homeowners.

1. Standing Seam Metal Roofing

Standing seam roofing features long, continuous panels that run from the ridge down to the eave. Raised seams interlock panels and conceal fasteners, creating a smooth, watertight surface that excels at shedding snow and preventing leaks.

• Pros: Leak‑proof seams, sleek modern look, minimal maintenance
• Cons: Higher installation cost, requires expert installation

2. Corrugated Metal Panels

Corrugated panels are formed into alternating ridges and valleys to add rigidity to thin steel sheets. Fasteners seated in the valleys, paired with rubber washers, seal each screw hole and keep water out.

• Pros: Low material cost, quick installation
• Cons: Exposed fasteners need periodic washer replacement, more rain noise

3. Metal Shingles

Metal shingles are stamped to resemble asphalt, wood shake, or slate. Installed in overlapping courses like traditional shingles, they offer design versatility with metal’s durability.

• Pros: Broad style options, moderate weight
• Cons: Increased seams raise potential leak points, higher cost than simple panels

4. Stone‑Coated Steel Roofing

Stone‑coated steel starts with a steel core, covered by a zinc‑aluminum alloy for corrosion resistance, then topped with stone granules and sealed with acrylic. It mimics the appearance of tile or slate while retaining steel’s strength.

• Pros: Authentic tile or slate aesthetic, superior hail damping
• Cons: Heavier load on roof deck, premium pricing

5. Copper Roofing

Copper roofing consists of solid copper panels or shingles that develop a protective green patina over time. This natural finish seals the metal and creates a distinctive, evolving appearance.

• Pros: Exceptional longevity (70+ years), virtually maintenance‑free after patina forms
• Cons: Highest material and labor costs, requires specialized installation

6. Zinc Roofing

Zinc‑titanium alloy panels form a self‑healing patina that blends scratches and seals the surface. These roofs age gracefully and require almost no ongoing maintenance.

• Pros: Outstanding weathering, minimal expansion/contraction
• Cons: Premium price tier, limited installer availability

7. Aluminum Panels

Aluminum roofing uses lightweight panels in flat or ribbed profiles. Aluminum resists rust and is ideal for low-load applications and coastal climates.

• Pros: Naturally corrosion-resistant, lighter roof load
• Cons: Softer metal prone to dents, moderate hail resistance

Maintenance & Care

Proper upkeep extends your roof’s life, maintains warranties, and keeps performance high. Follow these seasonal and ongoing steps:

• Spring Inspection
  After ice and snow melts, remove leaves, branches, and any debris from valleys, gutters, and roofwalk areas. Use a soft-bristle broom or leaf blower to avoid scratching the finish. Check all fasteners and metal flashings; tighten loose screws and replace worn sealants.
• Summer Checkup
  Inspect the roof surface for signs of coating wear, fading, or chalking. Look for small dents caused by storm damage and have them professionally assessed. Clean the roof gently with a mild detergent solution and a soft brush to remove dirt and pollen.
• Fall Preparation
  Clear gutters and downspouts to prevent clogs. Examine edge metal, ridge caps, and penetration flashings (chimneys, vents) for cracks or gaps. Touch up minor scratches or exposed metal with manufacturer-approved coating to stop corrosion.
• Winter Monitoring
  Ensure snow guards and ice belts are secure to control snow slide. From inside the attic, check for any signs of moisture, drips, or frost buildup on the underside of the roof deck. Address any leaks immediately to prevent interior damage.
• Professional Inspections
  Every three to five years, engage a certified metal roofing inspector to evaluate seam integrity, coating condition, and overall system health. Their report can support warranty claims and guide necessary repairs before they worsen.
• Record-Keeping
  Maintain a log of all inspections, cleaning dates, repairs, and warranty certificates. Include photos of work completed and any damaged areas. This documentation strengthens warranty coverage and assists future homeowners.
• Avoid Harsh Methods
  Never use high-pressure washers or abrasive cleaners. Avoid walking on the roof unless absolutely necessary, and always use proper safety equipment.

Consistent maintenance ensures your metal roof remains a durable, worry-free asset for decades. By following these steps, you protect your investment and maintain the beauty and function of your home’s exterior.

How to Choose the Right Metal Roof

Consider these six quick‑scan factors when selecting a metal roof system:

• Budget & Payback
  Choose corrugated panels for the lowest upfront cost or standing seam for longer payback and minimal maintenance.
• Weather Performance
  In hail‑prone zones, prefer Class 4 impact–rated standing seam or stone‑coated steel. For steep slopes, smooth panels like standing seam or copper shed snow effectively.
• Style & Curb Appeal
  Historic homes pair well with metal shingles or stone‑coated steel that mimic traditional materials. Modern residences look crisp with standing seam or ribbed aluminum.
• Maintenance Level
  If near‑zero upkeep is essential, select copper or zinc for self‑patina protection. Exposed‑fastener options (corrugated) require washer checks every 10–15 years.
• Structural Capacity & Warranty
  Verify roof deck can support heavier metals (stone‑coated, copper). Prioritize non‑prorated, transferable warranties: finish (20–30 yrs), material (30–80+ yrs), workmanship (10–20 yrs).
• Long‑Term Value & Resale
  Premium metals (copper, zinc, standing seam) often boost home resale value. Keep detailed installation and maintenance records to preserve transferable warranties.
