Asphalt vs Metal Roofing: Pros and Cons

Cost is the first factor most homeowners consider, and it's where asphalt has a clear advantage:

Asphalt shingles:

• 3-tab: $350–$500 per square (100 sq ft)
• Architectural: $450–$700 per square
• Typical 2,000 sq ft home: $8,000–$16,000 installed

Metal roofing:

• Corrugated: $600–$1,000 per square
• Standing seam: $900–$1,400 per square
• Typical 2,000 sq ft home: $14,000–$28,000 installed

Metal roofing costs 50-100% more than asphalt upfront. However, the cost comparison changes when you factor in lifespan — a metal roof lasts 2-3x longer, meaning you might replace an asphalt roof twice while a metal roof is still going strong.

20-year cost comparison (2,000 sq ft home):

• Asphalt: $12,000 initial + $12,000 replacement at year 20 = $24,000
• Metal: $20,000 initial (no replacement needed) = $20,000

Over the long term, metal can actually be less expensive — especially if you plan to stay in your home for 20+ years.

Asphalt shingles:

• Lifespan: 15-30 years (3-tab: 15-20, architectural: 20-30)
• Wind resistance: 60-130 mph (architectural shingles are more wind-resistant)
• Impact resistance: Moderate; hail can crack or bruise shingles
• Fire resistance: Class A (good)
• Algae resistance: Varies; some shingles have algae-resistant granules

Metal roofing:

• Lifespan: 40-70 years (some last even longer)
• Wind resistance: 110-160+ mph (excellent)
• Impact resistance: Good; most metal roofs earn Class 3 or 4 impact ratings (may qualify for insurance discounts)
• Fire resistance: Class A (excellent — metal doesn't burn)
• Corrosion resistance: Modern metal roofs have protective coatings that last decades

Metal is significantly more durable. It handles high winds, hail, and fire better than asphalt. If you live in an area with severe weather — hurricanes, hail storms, or wildfire risk — metal roofing provides superior protection.

This is where metal roofing has a significant advantage:

Asphalt shingles:

• Absorb heat (especially dark colors)
• Can increase attic temperatures by 20-40°F
• Increase cooling costs in hot climates
• "Cool roof" asphalt shingles (with reflective granules) are available but less effective than metal

Metal roofing:

• Reflect solar radiation (especially with "cool" paint finishes)
• Can reduce cooling costs by 10-25%
• Some metal roofs qualify for Energy Star and may qualify for utility rebates
• Can be installed with an air gap between the metal and roof deck, providing additional insulation

In hot climates, the energy savings from a metal roof can offset the higher upfront cost over 10-15 years. In cold climates, the energy difference is less significant since heating (not cooling) is the primary energy use.

Tax credits and rebates: Some metal roofs with appropriate Energy Star or Cool Roof ratings qualify for federal tax credits or local utility rebates. Check what's available in your area.

The appearance of your roof significantly affects your home's curb appeal:

Asphalt shingles:

• Available in many colors and styles
• Architectural shingles have a dimensional, textured look
• Some premium shingles mimic wood shake or slate
• Familiar, traditional appearance that suits most home styles
• Can look "flat" or less premium compared to other materials

Metal roofing:

• Available in panels (standing seam, corrugated) and shingles/tiles
• Wide range of colors including energy-efficient "cool" colors
• Standing seam has a modern, clean appearance
• Metal shingles/tiles can mimic wood, slate, or tile
• Can look "industrial" on traditional homes if not chosen carefully
• May not suit all architectural styles (consult with a designer if unsure)

Home value: Both materials can add value, but metal roofing is increasingly seen as a premium feature. Some studies show that metal roofing can increase home value by 1-6% and may make the home sell faster. Buyers increasingly value longevity and energy efficiency, both of which favor metal.

Asphalt shingles:

• Maintenance: Low; inspect annually, replace damaged shingles promptly
• Repair: Easy and inexpensive; individual shingles can be replaced
• Vulnerability: Algae/moss growth in humid climates (clean with zinc strips or wash)
• Granule loss over time (normal but indicates aging)

Metal roofing:

• Maintenance: Very low; occasional inspection, keep debris off
• Repair: More difficult and expensive; matching paint colors can be challenging
• Vulnerability: Can dent from large hail (though most modern metal roofs are impact-rated)
• Fasteners may need checking over time (on exposed-fastener systems; standing seam has concealed fasteners)
• Scratches can expose metal to corrosion (touch up with matching paint)

Asphalt is easier and cheaper to repair. Metal requires less maintenance overall but is more expensive to repair when damage does occur. If you live in an area with frequent hail, consider impact-rated metal roofing to minimize dent damage.

Asphalt shingles:

• Petroleum-based product
• Shorter lifespan means more frequent replacement and more waste
• Can be recycled into road material in some areas (check local options)
• Most old shingles end up in landfills

Metal roofing:

• Often made from recycled metal (30-60% recycled content)
• 100% recyclable at end of life
• Longer lifespan means less waste over time
• Can sometimes be installed over existing roofing, eliminating tear-off waste
• Lighter weight reduces transportation energy

Metal roofing has a significantly lower environmental impact over its lifecycle. If sustainability is a priority, metal is the clear choice.

Choose asphalt if:

• Budget is the primary concern
• You plan to sell the home within 10-15 years
• You prefer a traditional, familiar appearance
• You live in a mild climate without severe weather
• You want easy, inexpensive repairs

Choose metal if:

• You plan to stay in the home for 20+ years (long-term value)
• You live in a hot climate (energy savings)
• You live in an area with severe weather (hurricanes, hail, wildfires)
• You want a low-maintenance roof
• Sustainability is important to you
• You want to increase your home's value and marketability
• You like the modern or distinctive appearance of metal

Both materials are excellent choices for the right situation. Talk to a qualified roofing contractor about your specific home, climate, and priorities to make the best decision.
