Choose Asphalt Shingles If:

  • Budget is your primary concern
  • You plan to sell within 10-15 years
  • Your home is inland from the coast
  • HOA restrictions limit metal options

Choose Metal Roofing If:

  • You want a roof that lasts 50+ years
  • Hurricane protection is a priority
  • You want to reduce energy bills 20-25%
  • You live near the ocean (salt air)

The Great Roofing Debate: Asphalt vs Metal

Choosing between asphalt shingles and metal roofing is one of the most significant decisions homeowners face when replacing their roof. In coastal South Carolina, this choice becomes even more critical due to our unique climate challenges: hurricanes, salt air corrosion, intense humidity, and punishing UV exposure.

At Weather Shield Roofing, we install both asphalt and metal roofing systems throughout Myrtle Beach and the Grand Strand. After completing thousands of installations, we have deep insight into how each material performs in our coastal environment. This comprehensive guide will help you understand the real differences between these roofing materials so you can make an informed decision for your home.

The truth is, neither material is universally "better" than the other. The right choice depends on your budget, timeline, location, and priorities. Some homeowners are better served by quality asphalt shingles, while others will benefit significantly from investing in metal roofing. Let us walk you through every factor that matters.

Lifespan Comparison: 15-25 Years vs 50-70 Years

Asphalt Shingle Lifespan

  • 3-Tab Shingles: 12-18 years coastal
  • Architectural Shingles: 18-25 years coastal
  • Premium Shingles: 20-30 years coastal

Note: Coastal lifespans are 25-30% shorter than inland due to salt air, humidity, and UV exposure.

Metal Roofing Lifespan

  • Corrugated Metal: 30-50 years
  • Standing Seam Steel: 50-60 years
  • Aluminum Standing Seam: 70+ years
  • Copper/Zinc: 80-100+ years

Metal roofing often outlasts the building structure itself.

The lifespan difference between asphalt and metal roofing is the single most important factor in the long-term value comparison. A homeowner who installs asphalt shingles will typically need to replace their roof 2-3 times during the same period a single metal roof would last.

In Myrtle Beach specifically, asphalt shingle lifespans are reduced by our coastal environment. The combination of salt air, 70-80% humidity, intense UV radiation, and occasional hurricane impacts causes shingles to degrade faster than manufacturer warranties suggest. We regularly see asphalt roofs needing replacement at 15-18 years in oceanfront communities.

  • Kynar coatings last 30-40 years

For South Carolina homeowners in hurricane territory, weather resistance is paramount. Metal roofing excels in every weather category that matters for our coastal climate. Standing seam metal with concealed fasteners provides superior wind uplift resistance because there are no exposed edges for wind to catch. During Hurricane Florence (2018) and Hurricane Ian (2022), metal roofs in our service area consistently outperformed asphalt shingle roofs.

Asphalt shingles can still provide adequate protection when properly installed with enhanced wind resistance features like 6-nail fastening patterns and starter strips. However, even premium asphalt shingles cannot match the absolute wind resistance of mechanical-seam standing seam metal roofing.

Energy Efficiency Comparison

Asphalt Shingles

  • Absorbs 80-95% of solar heat
  • Attic temperatures: 140-170 degrees F in summer
  • Energy savings: 5-10% with cool-roof options

Light-colored asphalt shingles with reflective granules can improve efficiency, but still absorb significantly more heat than metal.

Metal Roofing

  • Reflects 70% of solar radiation
  • Attic temperatures: 30-50 degrees F cooler
  • Energy savings: 20-25% on cooling costs

ENERGY STAR certified metal roofing qualifies for federal tax credits and utility rebates in South Carolina.

In Myrtle Beach, where air conditioning runs 6-8 months per year, the energy efficiency difference between asphalt and metal roofing translates to substantial savings. Metal roofing with reflective coatings dramatically reduces the heat load on your home by reflecting solar energy rather than absorbing it.

The 20-25% reduction in cooling costs adds up significantly over the life of a metal roof. For a home spending around a typical amount annually on summer cooling, metal roofing can provide meaningful savings each year. Over 50 years, this energy savings alone can offset a significant portion of the higher initial investment in metal roofing.

Maintenance Requirements

Asphalt Shingle Maintenance

  • AnnualProfessional inspection and debris removal
  • As NeededReplace cracked, curled, or missing shingles
  • Every 3-5 YearsAlgae/moss treatment in humid climates
  • Post-StormInspection for hail damage, wind damage
  • OngoingGutter cleaning to prevent granule buildup

Metal Roofing Maintenance

  • AnnualVisual inspection (can be DIY)
  • As NeededRinse with garden hose to remove debris
  • Every 10+ YearsCheck sealants around penetrations
  • RareTouch-up paint on scratches (if any)

Metal roofing requires significantly less maintenance over its lifespan.

Insurance Discounts and Resale Value

Insurance Considerations

Asphalt Shingles:

0-5% discount for impact-resistant Class 4 shingles. Standard shingles typically receive no discount.

Metal Roofing:

10-35% premium discount due to Class A fire rating, Class 4 impact resistance, and superior wind resistance.

In coastal South Carolina where insurance premiums are high, these discounts can represent significant annual savings.

Resale Value Impact

Asphalt Shingles:

Increases home value 1-3%. New roof is expected by buyers; limited differentiation from competitors.

Metal Roofing:

Increases home value 1-6%. Seen as premium upgrade. Transferable 50-year warranty appeals to buyers.

In coastal markets, buyers specifically seek homes with storm-resistant features, making metal roofing a strong selling point.

Environmental Impact

Asphalt Shingles

  • Petroleum-based product, non-renewable materials
  • 11 million tons of shingles reach landfills annually in the US
  • Limited recycling options (some areas have programs)
  • 2-3 roof replacements multiply environmental impact
  • Recycled content options available from some manufacturers

Metal Roofing

  • Often contains 25-95% recycled content
  • 100% recyclable at end of life
  • One installation lasts 50-70+ years
  • Reduces energy consumption 20-25%
  • Can be installed over existing roof, reducing waste

Aesthetic Options and Curb Appeal

Asphalt Shingle Styles

  • 3-Tab Shingles: Traditional flat appearance, most economical
  • Architectural/Dimensional: Multi-layer, shadowed effect, most popular
  • Designer/Luxury: Mimics slate, shake, or tile appearance
  • Colors: Dozens of options from black to beige to blue-gray

Asphalt shingles offer the widest variety of colors and profiles, fitting virtually any architectural style.

Metal Roofing Styles

  • Standing Seam: Sleek, modern vertical lines
  • Metal Shingles: Mimic traditional shingles, slate, or shake
  • Stone-Coated Steel: Textured appearance like tile or wood
  • Corrugated: Classic ribbed profile, rustic or industrial
  • Colors: 40+ colors with fade-resistant Kynar coatings

Modern metal roofing can match almost any home style, from traditional to contemporary.

A common misconception is that metal roofing looks industrial or commercial. Today's metal roofing comes in styles that beautifully complement traditional homes, coastal cottages, modern designs, and everything in between. Stone-coated metal shingles are virtually indistinguishable from traditional materials but with far superior performance. Learn more about metal roofing options available for your home.

Our Recommendation for Coastal South Carolina

After installing thousands of roofs in Myrtle Beach, North Myrtle Beach, Conway, and throughout the Grand Strand, our recommendation is clear:

For oceanfront and near-coast properties: Aluminum standing seam metal roofing

The combination of hurricane resistance, salt air durability, and energy efficiency makes metal the smart choice for properties within 1-2 miles of the ocean.

For inland properties: Quality architectural shingles OR metal roofing

Both materials perform well when you are further from salt air exposure. The choice depends on your budget, timeline, and priorities.

Frequently Asked Questions

Is a metal roof worth it over asphalt shingles?+
Yes, metal roofing is worth it for most South Carolina homeowners. While the upfront cost is 2-3x higher than asphalt shingles, metal roofs last 50-70 years compared to 15-25 years for asphalt. When you factor in the elimination of 2-3 roof replacements, 20-25% energy savings, insurance discounts, and increased home value, metal roofing typically provides better lifetime value. For coastal homes facing hurricanes and salt air, the durability advantages make metal an especially smart investment.
How much more does a metal roof cost compared to asphalt?+
Metal roofing typically costs 2-3x more than asphalt shingles for initial installation. For a typical 2,000 sq ft home in Myrtle Beach, asphalt shingles generally cost significantly less than standing seam metal roofing. However, over a 50-year period, metal often costs less when you account for the 2-3 asphalt roof replacements needed during that time. Contact us for a personalized quote based on your specific roof.
Which roof is better for hurricanes: metal or asphalt?+
Metal roofing is significantly better for hurricane resistance. Standing seam metal roofs with concealed fasteners are rated for winds up to 140-180 mph, while standard asphalt shingles are typically rated for 110-130 mph. In our coastal South Carolina climate, where hurricanes are a regular threat, metal roofing provides superior protection against wind uplift and flying debris. Many homeowners receive insurance discounts of 10-35% for metal roofing.
Do metal roofs make the house hotter?+
No, modern metal roofs actually keep homes cooler than asphalt shingles. Metal roofing with reflective coatings reflects 70% of solar radiation compared to only 5-15% for dark asphalt shingles. This reduces attic temperatures by 30-50 degrees F and cuts cooling costs by 20-25%. Metal roofs are ENERGY STAR certified and can qualify for tax credits and utility rebates in South Carolina.
How long does asphalt shingle roofing last in coastal South Carolina?+
In coastal South Carolina, asphalt shingle roofs typically last 15-20 years, compared to 20-30 years in inland areas. The combination of salt air, high humidity, intense UV exposure, and hurricane-force winds accelerates shingle degradation. Architectural shingles last slightly longer (18-22 years) than 3-tab shingles (12-18 years) in coastal environments. Regular maintenance and choosing algae-resistant shingles can help extend lifespan.
Are metal roofs noisy when it rains?+
No, this is a common myth. Modern metal roofs installed over solid roof decking with proper underlayment and attic insulation are actually quieter than asphalt shingles during rain. The solid deck, underlayment, and insulation create effective sound barriers. In blind tests, homeowners cannot distinguish between metal and asphalt roofs during rainstorms. Standing seam systems with concealed fasteners are especially quiet.
Will a metal roof interfere with cell phone or internet signals?+
Metal roofs do not significantly interfere with cell phone or internet signals. While metal can slightly reduce signal strength inside the home, modern cell networks and WiFi routers easily compensate for this. If you have a weak signal now, a metal roof will not make it noticeably worse. Most homeowners report no difference in cell reception or WiFi performance after installing a metal roof.
Can I put a metal roof over existing asphalt shingles?+
Yes, in many cases metal roofing can be installed over existing asphalt shingles, which saves money on tear-off and disposal. However, this depends on local building codes, the condition of existing shingles, and roof structure. A maximum of one existing layer is typically allowed. We recommend a professional inspection to determine if overlay installation is appropriate for your home.
Which roof type increases home resale value more?+
Metal roofing typically increases home value by 1-6%, while a new asphalt shingle roof increases value by about 1-3%. In coastal markets like Myrtle Beach, buyers specifically value metal roofing for its storm resistance and low maintenance. The transferable warranty on metal roofs (often 50+ years remaining) makes homes more attractive to buyers. Metal roofing is increasingly seen as a premium upgrade.
What is the best roofing material for Myrtle Beach homes?+
For most Myrtle Beach homes, metal roofing is the best choice due to its superior hurricane resistance, salt air durability, and energy efficiency. Aluminum standing seam is ideal for oceanfront properties, while Kynar-coated steel works well for homes further inland. However, quality architectural asphalt shingles remain a solid choice for homeowners prioritizing lower upfront costs, especially for homes not directly on the coast.
