Metal Roofing: Pros, Cons, and Cost Guide

Types of Metal Roofing

Not all metal roofing is the same. The type determines cost, appearance, longevity, and maintenance requirements:

• Standing seam: The premium option. Raised interlocking seams conceal all fasteners, preventing water infiltration at fastener points. Panels float on clips that accommodate thermal expansion. The most durable and expensive option -- expect 40-70+ years of service.
• Exposed fastener panels (corrugated, ribbed, 5-V crimp): Less expensive and common on agricultural, commercial, and residential buildings. Fasteners penetrate the panel surface and rely on rubber gaskets to stay weathertight. Gaskets degrade over time (20-30 years) and require periodic re-sealing or fastener replacement.
• Metal shingles: Steel or aluminum panels designed to mimic asphalt, tile, or wood shake appearance. Less expensive than standing seam, more expensive than corrugated. Exposed fastener but with a more traditional residential appearance.
• Copper and zinc: Premium specialty materials with exceptional longevity (80-100+ years) used primarily in high-end residential and historic restoration. Cost is significantly higher than steel or aluminum.

Metal Roofing Cost Breakdown

For a 2,000 sq ft home (approximately 20-22 squares of roofing), installed costs run $10,000-$18,000 for corrugated, $14,000-$26,000 for metal shingles, and $20,000-$40,000+ for standing seam. Compare to asphalt shingle replacement costs over the same lifespan.

Pros of Metal Roofing

• Exceptional lifespan. 40-70 years vs 25-30 for asphalt shingles means you are likely buying your last roof. For long-term homeowners, the economics often work out favorably over 50 years.
• Wind resistance. Metal roofing systems are engineered for wind resistance well above what standard asphalt shingles can handle. Many systems are rated for 110-140 mph winds.
• Fire resistance. Metal is non-combustible. Class A fire rating on most systems -- relevant in wildfire-prone areas.
• Hail performance. Standing seam metal performs well in hail because there are no granules to lose and the metal itself resists impact. Impact-resistant ratings are available.
• Energy efficiency. Reflective metal coatings can reduce cooling loads in hot climates by reflecting solar energy rather than absorbing it.
• Low maintenance. Metal roofs require very little maintenance compared to asphalt -- mainly periodic inspection and fastener/sealant maintenance on exposed fastener systems.
• Snow shedding. Metal roofs shed snow efficiently, reducing load and ice dam risk in snowy climates.

Cons of Metal Roofing

• Higher upfront cost. Metal roofing costs 2-4x more than standard asphalt shingle installation upfront. This is the primary barrier for most homeowners.
• Noise. Rain and hail are louder on metal than on asphalt shingles. A proper underlayment system reduces noise significantly, but never entirely.
• Denting. Large hail can dent softer aluminum panels. Steel is more resistant. Impact-resistant ratings mitigate this but do not eliminate it.
• Expansion and contraction. Metal expands and contracts significantly with temperature changes. Improper installation that does not account for this movement causes premature fastener failure and seam issues.
• Specialist required. Metal roofing installation requires specialist contractors. General roofing contractors are not always qualified for standing seam systems. This limits your contractor options and creates repair challenges.
• Resale complexity. In some markets, buyers are unfamiliar with metal roofing and may not value it appropriately. This can complicate financing and insurance conversations.

When Metal Roofing Makes Sense

• You plan to stay in the home for 20+ years and want your last roof
• You are in a high-wind or hurricane-prone area
• You are in a wildfire-risk zone where fire resistance matters
• You are in a high-hail zone (standing seam handles hail better than most asphalt)
• You have a low-slope section where asphalt shingles are not appropriate
• Your region has a strong metal roofing market with qualified local contractors

Metal Roof Maintenance

Metal roofs need far less maintenance than asphalt but are not zero-maintenance:

• Inspect fasteners on exposed fastener systems every 10-15 years and re-seal or replace as needed
• Clear debris -- branches and leaves -- from valleys and gutters as they accumulate
• Inspect sealant around penetrations (pipe boots, skylights, chimneys) every 10 years
• Touch up damaged paint or coating to prevent rust on steel systems
• Do not walk metal roofing without proper non-scratch footwear -- foot traffic can damage coatings
