Best Roofing Materials for Myrtle Beach (Coastal SC Guide)
Choosing a roofing material for a home in Myrtle Beach is a fundamentally different decision than choosing one in Charlotte, Greenville, or anywhere inland. Your roof has to survive 130 to 150 mph hurricane winds, constant salt air corrosion, extreme UV exposure, and 50+ inches of annual rainfall. A material that lasts 30 years in Ohio might barely make it to 18 in the Grand Strand. This guide ranks every major roofing material specifically for coastal South Carolina performance — not generic national averages.
We install every material on this list. This ranking is based on what we see perform best on the homes we service across Myrtle Beach, North Myrtle Beach, Surfside Beach, Pawleys Island, and the surrounding Grand Strand area.
Quick answer: For most Myrtle Beach homeowners, impact-resistant architectural shingles are the best value, and standing seam metal is the best long-term investment.

What Makes Coastal SC Different for Roofing Materials
Before comparing materials, understand the four environmental factors that separate Myrtle Beach from the rest of the state:
- Salt air corrosion — Airborne salt particles corrode any unprotected metal within 3 to 5 years. Homes within 1 mile of the ocean face the most aggressive exposure. This eliminates some materials and requires upgraded fasteners on all others. See our salt air roof damage guide for details.
- Wind Zone III requirements — Myrtle Beach requires roofing rated for 130 to 150 mph winds. This means 6-nail patterns, enhanced underlayment, and wind-rated ridge caps at minimum.
- UV degradation — 215+ sunny days per year breaks down asphalt compounds and coating systems faster than in northern climates. Materials need to be rated for high UV zones.
- Humidity and biological growth — 70%+ average humidity promotes algae, moss, and mold growth on roof surfaces, particularly on north-facing slopes.

*Standing seam salt air rating assumes Galvalume or aluminum panels with PVDF coating and stainless steel concealed fasteners.
#1: Standing Seam Metal Roofing (Best Overall)
Standing seam metal is our top recommendation for Myrtle Beach homeowners who can afford the upfront investment. The concealed fastener design is what makes it work on the coast — there are no exposed screws or neoprene washers to corrode in salt air.
Why It Works on the Coast
- Concealed clips allow thermal expansion without stress on fastener holes
- Galvalume (55% aluminum, 43.5% zinc, 1.5% silicon alloy) resists salt air corrosion for 40+ years with PVDF coating
- Continuous interlocking seams create a monolithic surface that sheds wind
- No granules to lose, no asphalt to degrade under UV
- Sheds debris and water faster than any other residential material
Coastal Specifications
- Panel material: Galvalume (24-gauge minimum) or marine-grade aluminum (0.032" minimum)
- Coating: PVDF (Kynar 500 / Hylar 5000) — do not accept SMP (silicone-modified polyester) within 3 miles of the ocean
- Fasteners: Stainless steel Type 304 concealed clips (Type 316 within 1,500 feet of waterline)
- Seam type: Mechanical lock or snap-lock rated for 140+ mph
- Underlayment: High-temp synthetic rated for metal roofing (standard felt traps moisture)

Insurance advantage: Metal roofing qualifies for 10 to 25% premium reductions with most SC coastal insurers. Combined with a FORTIFIED Roof designation, total savings can reach 20 to 35% — which can offset $500 to $1,000+ per year on a typical Myrtle Beach policy.
#2: Impact-Resistant Architectural Shingles (Best Value)
Architectural shingles account for roughly 75% of residential re-roofs in the Grand Strand. When you choose the right product line for coastal conditions, they deliver solid performance at the most accessible price point.
Best Shingle Lines for Myrtle Beach
- GAF Timberline HDZ — The most installed shingle in America. LayerLock technology provides a 130 mph wind warranty with standard 4-nail install. SBS-modified option available for enhanced flexibility. StainGuard Plus algae protection rated for 25 years.
- Owens Corning Duration FLEX — SBS-modified throughout (not just a coating). Better thermal cycling performance than standard architectural shingles. 130 mph wind rating. TruDefinition color technology resists UV fading.
- CertainTeed Landmark PRO — 130 mph wind warranty. NailTrak nailing guide for consistent placement. Max Def colors with algae resistance. Good value mid-range option.
- Atlas StormMaster Slate (Class 4) — Impact-resistant with the highest insurance discount potential. SBS-modified with Scotchgard algae protection. Core 4 rating: Class 4 impact, 130 mph wind, Class A fire, algae resistant.
Key Coastal Installation Requirements
In Myrtle Beach (Wind Zone III), shingles must be installed with a 6-nail pattern regardless of the manufacturer’s standard recommendation. Enhanced underlayment with self-adhering ice and water shield at all eaves and valleys is code-required. Use hot-dipped galvanized or stainless steel roofing nails only — standard electro-galvanized nails corrode too fast in salt air.

#3: Concrete Tile (Best Longevity)
Concrete tile offers the longest lifespan of any mainstream residential roofing material. The tiles themselves are completely immune to salt air corrosion — a significant advantage over metal in the most aggressive coastal environments. The trade-off is weight: at 900 to 1,200 pounds per roofing square, most Myrtle Beach homes need structural reinforcement before tile installation.
Salt Air Performance
Concrete tiles score the highest possible salt air resistance. Portland cement, sand, and iron oxide pigments are non-reactive with salt spray. The tiles will not corrode, pit, or degrade from marine exposure. The only salt-vulnerable components are the fasteners (must be stainless steel Type 316) and metal flashing (must be painted aluminum or stainless steel).
The Weight Factor
This is the dealbreaker for most homeowners. A 2,000 square foot concrete tile roof adds 18,000 to 24,000 pounds to your structure. A structural engineer evaluation ($300 to $800) is required before any permits are issued. Reinforcement can add $1,000 to $10,000 depending on the current framing capacity. Read our complete concrete tile roof guide for full details.
#4: Clay Tile (Premium Longevity)
Clay tile shares concrete tile’s immunity to salt air corrosion with two additional advantages: permanent color (the pigment goes all the way through the tile) and a longer lifespan of 75 to 100+ years. The downsides are higher cost ($12 to $25 per square foot versus $9 to $18 for concrete) and the same structural requirements.
Clay tile is best for high-value coastal properties — beachfront homes, oceanfront condominiums, and luxury developments where the material’s Mediterranean aesthetic complements the architecture and the owner plans to hold the property long term. See our concrete vs clay comparison for a detailed side-by-side.
#5: Composite (Synthetic) Shingles (Rising Option)
Composite shingles made from engineered polymers are a newer option that is gaining traction in coastal markets. Products like DaVinci Roofscapes and Brava Roof Tile mimic the appearance of slate or cedar shake while being lighter, impact resistant, and impervious to moisture and salt air.
- Class 4 impact resistance (highest rating)
- 130 to 150 mph wind ratings
- No salt air corrosion (polymer construction)
- 30 to 50 year manufacturer warranty
- Lighter than concrete or clay tile (no structural reinforcement needed)
- Cost: $7 to $12 per square foot installed
The downside is limited long-term performance data in coastal SC specifically. These products have been on the market for about 15 years, so we do not yet have 30+ years of real-world coastal data. That said, the engineering and lab testing results are promising. Learn more in our composite shingles guide.
Materials to Avoid in Coastal Myrtle Beach
3-Tab Shingles
While technically code-compliant with a 6-nail installation, 3-tab shingles are a poor investment on the coast. Their single layer design provides minimal wind uplift resistance compared to architectural shingles. A 60 to 80 mph real-world wind resistance means the first strong tropical system will likely strip sections. The 12 to 15 year coastal lifespan means you are replacing the roof again before an architectural shingle roof would even need its first inspection. The cost savings of $1 to $2 per square foot over architectural shingles does not justify the dramatically shorter life and worse storm performance.
Exposed-Fastener Metal Panels
Exposed-fastener metal (screw-down panels like R-panel or PBR-panel) is the most common type of metal roofing on agricultural buildings and is sometimes sold for residential use at low prices. On the coast, this is a mistake. The exposed screws penetrate the panel surface and rely on neoprene washers to seal the hole. Salt air degrades the neoprene within 7 to 12 years, and the screw heads themselves corrode. Each screw becomes a potential leak point. Thermal expansion also works against exposed-fastener systems, causing the screw holes to enlarge over time. For residential coastal use, standing seam is always the better choice.
Wood Shakes
Cedar shakes deteriorate rapidly in the Myrtle Beach climate. The combination of constant moisture, salt air, and intense UV causes splitting, curling, and rot far faster than in the Pacific Northwest where cedar roofs originated. Maintenance costs (annual treatment, replacing individual shakes) often exceed the annualized cost of more durable materials. Many SC coastal insurers refuse to write policies on wood shake roofs due to the fire risk and storm vulnerability.
Total Cost of Ownership Comparison (30-Year Period)
The cheapest material upfront is rarely the cheapest over time. This table shows the true 30-year cost for a typical 2,000 square foot Myrtle Beach home, including replacements when the material does not last 30 years.
| Material | Install Cost | Replacements | 30-Year Total |
|---|---|---|---|
| 3-tab shingles | $7,000 – $11,000 | 1 – 2 more | $14,000 – $33,000 |
| Architectural shingles | $9,000 – $14,000 | 0 – 1 more | $9,000 – $28,000 |
| Standing seam metal | $20,000 – $36,000 | 0 | $20,000 – $36,000 |
| Concrete tile | $18,000 – $36,000 | 0 | $18,000 – $36,000 |
| Composite shingles | $14,000 – $24,000 | 0 | $14,000 – $24,000 |
The 30-year math clearly favors investing more upfront. Standing seam metal, concrete tile, and composite shingles all cost the same or less than doing two shingle roofs over the same period — and they provide better storm protection and insurance savings throughout.

Which Material Is Right for Your Situation?
Best Budget Choice: Architectural Shingles
If your budget is under $15,000 for a 2,000 square foot roof, impact-resistant architectural shingles (GAF Timberline HDZ or Atlas StormMaster Slate) are the clear winner. The 18 to 25 year coastal lifespan and 130 mph wind rating deliver reliable performance at the lowest entry price. Pair with a FORTIFIED Roof installation for maximum insurance savings.
Best Long-Term Investment: Standing Seam Metal
If you plan to own your home for 15+ years and can invest $20,000 to $36,000, standing seam metal is the best overall value in Myrtle Beach. You never replace it, maintenance is minimal, storm damage is rare, and the insurance savings compound year after year.
Best for Oceanfront Properties: Concrete or Clay Tile
For homes on or immediately adjacent to the beach, concrete or clay tile eliminates the salt corrosion variable entirely. The tiles will outlast the home. Combined with stainless steel Type 316 fasteners and proper flashing, tile roofs on oceanfront properties can last 75+ years with virtually no weather-related degradation.
Best for Selling Soon: Architectural Shingles
If you plan to sell within 5 to 10 years, architectural shingles provide the best return. A new shingle roof adds curb appeal and eliminates the “roof condition” negotiation from the sale. The ROI on a $12,000 shingle roof when selling exceeds the ROI on a $30,000 metal roof because buyers do not pay dollar-for-dollar for the upgrade.
Frequently Asked Questions
What is the best roofing material for a coastal home in Myrtle Beach?
Standing seam metal roofing with Galvalume or aluminum panels and a PVDF coating is the best overall choice. It resists salt air corrosion, handles 140 to 180 mph winds, lasts 40 to 70 years, and qualifies for 10 to 25% insurance discounts. For tighter budgets, impact-resistant architectural shingles at $4.50 to $7 per square foot are the best value.
Do metal roofs rust in Myrtle Beach salt air?
Standing seam metal with proper material selection does not rust. Use Galvalume or aluminum panels with PVDF coating. Avoid galvanized steel and exposed-fastener panels. Galvalume with Kynar 500 coating withstands 10,000+ hours of salt spray testing. Exposed-fastener panels are the problem — the screws and neoprene washers corrode within 7 to 12 years.
How long do asphalt shingles last in Myrtle Beach?
3-tab shingles rated for 25 years typically last 12 to 15 years in coastal conditions. Architectural shingles rated for 30 years last 18 to 25 years. Salt air, UV, humidity, and storms accelerate granule loss and underlayment breakdown. SBS-modified shingles perform better because they flex rather than crack with thermal cycling.
Are tile roofs worth it in Myrtle Beach?
Yes for high-value homes where the owner stays 20+ years. Concrete tile lasts 50 to 100 years and is immune to salt air. However, structural reinforcement ($1,000 to $10,000) is usually needed. Total cost is $18,000 to $36,000 for a 2,000 square foot home. On a per-year basis, tile can cost less than shingles that need replacing every 20 years.
What roofing material is best for hurricane resistance?
Standing seam metal at 140 to 180 mph is best for most homes. Concrete and clay tile also excel at 150+ mph but require structural reinforcement. Impact-resistant architectural shingles at 130 mph with 6-nail installation are the minimum recommended for Wind Zone III compliance.
Which roofing material gives the best insurance discount in SC?
A FORTIFIED-certified standing seam metal roof earns the largest discount: 20 to 35% off annual premiums. Metal alone gets 10 to 25%. Class 4 impact-resistant shingles get 5 to 15%. On a $3,000 per year coastal premium, a FORTIFIED metal roof saves $600 to $1,050 annually.
