Metal vs. Asphalt Shingles: Which Best Withstands the Lowcountry Climate?

Drive through Old Town Bluffton or the neighborhoods of Palmetto Bluff, and you will notice a distinct architectural trend: the shiny, sleek lines of metal roofing.

While asphalt shingles have traditionally been the standard across South Carolina, metal roofing is seeing a massive surge in popularity. But is it just for the “Lowcountry look,” or is there a functional reason to switch?

At New River Roofing, we install both systems. Here is an honest comparison of how they stack up against the specific challenges of our coastal environment.

The Challenger: Metal Roofing (Galvalume & Aluminum)

Metal is tough, reflective, and undeniably stylish.

• Salt Air Resistance: This is the biggest factor for homes near the May River or Colleton River. Aluminum roofing does not rust, making it the superior choice for homes within a mile of saltwater.
• Wind Resistance: High-quality standing seam metal roofs can withstand gusts up to 140+ mph. Unlike shingles, there are no tabs to lift or peel off during a hurricane.
• Energy Efficiency: A “Cool Roof” metal system reflects the intense Lowcountry sun rather than absorbing it, potentially lowering your AC costs by 20-30% in July and August.
• Lifespan: Expect 40 to 70 years of service. It is likely the last roof you will ever buy.

The Defender: Asphalt Shingles (Architectural)

Asphalt is still the most common choice for a reason: it offers excellent performance at a lower price point.

• Cost: An asphalt shingle roof typically costs 50-60% less upfront than a standing seam metal roof.
• Aesthetics: Modern architectural shingles (like GAF Timberline) offer depth and shadow lines that mimic wood shake, fitting perfectly with HOA standards in communities like Sun City.
• Ease of Repair: If a tree limb falls on your roof, replacing a few shingles is quick and inexpensive. Repairing a dented metal panel is significantly more involved.

The Verdict: Which is Right for You?

• Choose Metal If: You plan to stay in your home for 15+ years, you live very close to the water, or you want the lowest possible cooling bills.
• Choose Asphalt If: You want a cost-effective, reliable roof that looks great and meets strict HOA guidelines without breaking the bank.
