Metal Roof Installation: Cost, Timeline & Process in Myrtle Beach

By David KarimiMarch 17, 202622 min read

A metal roof is one of the smartest long-term investments a homeowner in coastal South Carolina can make. It stands up to hurricanes, shrugs off salt air, cuts your energy bills, and can lower your insurance premiums — all while lasting two to three times longer than asphalt shingles. But it also costs significantly more upfront, and the installation process is more complex than a standard shingle job.

In this guide, we break down exactly what a metal roof installation costs in the Myrtle Beach area in 2026, walk through the full 8-step installation process, explain the realistic timeline, and cover why metal roofing is particularly well-suited to our coastal climate. Whether you are comparing quotes, budgeting a new build, or deciding between metal and shingles, this is everything you need to make an informed decision.

How Much Does Metal Roof Installation Cost in 2026?

Metal roof installation in the Myrtle Beach area costs $10 to $16 per square foot fully installed for most residential projects. For a typical 2,000 square foot home, that puts the total project cost between $20,000 and $40,000 depending on the metal type, roof complexity, and whether the existing roof needs to be torn off.

Here is a breakdown of what Myrtle Beach homeowners are paying for metal roof installations in 2026:

Metal Roof TypeCost Per Sq Ft (Installed)Total for 1,500 Sq FtTotal for 2,000 Sq Ft
Corrugated Steel Panels$8 – $12$12,000 – $18,000$16,000 – $24,000
Metal Shingles$10 – $14$15,000 – $21,000$20,000 – $28,000
Stone-Coated Steel$12 – $16$18,000 – $24,000$24,000 – $32,000
Standing Seam (Steel)$12 – $18$18,000 – $27,000$24,000 – $36,000
Standing Seam (Aluminum)$14 – $20$21,000 – $30,000$28,000 – $40,000
Copper$25 – $40$37,500 – $60,000$50,000 – $80,000

What is included in these prices: Materials, professional installation labor, synthetic underlayment, drip edge and flashing, ridge cap and trim, fasteners, and job site cleanup. Prices assume a standard tear-off of one layer of existing shingles. Add $1,000 to $2,500 for a second layer removal or extensive decking repairs.

What Drives the Cost Higher or Lower?

Several factors push your metal roof installation cost toward the high or low end of these ranges:

  • Roof complexity: Hips, valleys, dormers, skylights, and chimney penetrations all add labor time and custom flashing work. A complex roof can add 20–40% to the base cost.
  • Roof pitch: Steep roofs (8/12 and above) require safety equipment, slower work pace, and sometimes scaffolding, adding $1,000–$3,000.
  • Decking condition: If the plywood or OSB decking beneath the old roof is rotten or water-damaged, it must be replaced at $60–$100 per sheet.
  • Coastal coatings: PVDF/Kynar coatings (essential for salt air resistance) add $1–$2 per square foot compared to standard polyester paint.
  • Accessibility: Multi-story homes, limited driveway access, or landscaping obstructions can increase labor costs.
  • Permit and inspection fees: Horry County building permits for a full roof replacement typically run $200–$500.

Types of Metal Roofing: Pros, Cons, and Cost Comparison

Not all metal roofs are the same. The four main types each have distinct advantages, trade-offs, and ideal use cases. Here is how they compare for Myrtle Beach homes.

Standing Seam Metal Roofing

Standing seam is the premium choice and the most popular metal roofing system for residential homes in hurricane-prone areas. The panels have raised seams that interlock together, creating a continuous, watertight surface with no exposed fasteners.

  • Cost: $12–$18/sq ft (steel) or $14–$20/sq ft (aluminum)
  • Lifespan: 40–70 years
  • Wind rating: 140–180 mph (varies by manufacturer and attachment method)
  • Best for: Primary residences in coastal SC, hurricane zones, homeowners who want maximum longevity

Why we recommend it for Myrtle Beach: The concealed fastener system is the single biggest advantage in coastal environments. Exposed fasteners are the number one failure point on cheaper metal roofs — they corrode in salt air, back out in thermal cycling, and create leak points. Standing seam eliminates this entirely. Learn more in our standing seam vs corrugated comparison guide.

Corrugated Metal Roofing

Corrugated metal panels are the most affordable metal roofing option. The panels have a rippled or ribbed profile and are fastened with exposed screws that penetrate through the panel face into the decking or purlins below.

  • Cost: $8–$12/sq ft installed
  • Lifespan: 25–40 years
  • Wind rating: 110–140 mph (with proper fastener pattern)
  • Best for: Detached garages, workshops, agricultural buildings, budget-conscious projects

Coastal caution: The exposed fasteners on corrugated panels are a liability in salt air environments. The rubber washers that seal each screw penetration degrade in UV and salt exposure, typically requiring re-sealing every 10–15 years. For a primary residence within 15 miles of the coast, we generally steer homeowners toward standing seam or metal shingles instead.

Metal Shingles

Metal shingles are individual panels stamped or formed to look like traditional roofing materials — slate, wood shake, or dimensional asphalt shingles. They offer the aesthetics of conventional roofing with the durability of metal.

  • Cost: $10–$14/sq ft installed
  • Lifespan: 30–50 years
  • Wind rating: 120–160 mph (interlocking systems)
  • Best for: Homeowners who want metal durability but prefer a traditional roof appearance, HOA-regulated neighborhoods

Metal shingles are a solid middle ground for Myrtle Beach homeowners. The interlocking installation keeps fasteners concealed, and many manufacturers offer PVDF-coated options suitable for coastal exposure. They are also easier for most roofers to install compared to standing seam, which can keep labor costs lower.

Stone-Coated Steel

Stone-coated steel panels are made from galvanized steel coated with a layer of stone granules bonded with an acrylic resin. They mimic the look of clay tile, wood shake, or slate while providing the strength and weight advantages of metal.

  • Cost: $12–$16/sq ft installed
  • Lifespan: 40–60 years
  • Wind rating: 120–155 mph
  • Best for: Upscale neighborhoods, HOA communities, homeowners wanting a premium look without the weight of real tile or slate

Stone-coated steel performs well in coastal SC. The granule coating provides an extra layer of UV and corrosion protection. However, the stone coating can wear in extreme salt spray conditions over time. For properties directly on the oceanfront, standing seam with PVDF coating remains the more durable choice.

Metal Roof Installation Process: 8 Steps From Start to Finish

A professional metal roof installation is a structured process. Understanding each step helps you set realistic expectations, communicate with your contractor, and spot shortcuts that could compromise the finished product. Here is exactly how a proper metal roof installation works.

Step 1: Pre-Installation Inspection and Measurements

Before any work begins, your contractor should perform a thorough inspection of the existing roof. This includes measuring the total roof area (accounting for pitch), documenting penetrations (vents, chimneys, skylights), assessing the condition of the decking from inside the attic, and identifying any structural concerns. Accurate measurements determine material orders and prevent costly mid-project delays. At WeatherShield, we use drone measurements for complex roofs to ensure accuracy within 1%.

Step 2: Tear-Off of the Existing Roof

The old roofing material is stripped down to the decking. For asphalt shingle tear-offs, this typically takes a crew of 3–5 workers half a day for an average-sized home. All old shingles, underlayment, flashing, and debris are removed and loaded into a dumpster. This step is critical because it allows full inspection of the wood decking beneath — something that cannot happen if you install over existing shingles.

Step 3: Decking Inspection and Repair

With the old roof removed, the crew inspects every sheet of plywood or OSB decking for rot, water damage, delamination, and soft spots. Damaged sections are cut out and replaced with new structural-grade sheathing. In coastal SC, moisture intrusion is common, so expect at least a few sheets to need replacement on older homes. This step costs $60–$100 per 4x8 sheet but is non-negotiable — installing a new metal roof over compromised decking is the single biggest installation mistake you can make.

Step 4: Underlayment Installation

A high-quality synthetic underlayment is rolled out across the entire roof deck. For metal roofs in coastal SC, we use a high-temperature synthetic underlayment rated for metal roofing (standard felt paper is not suitable because metal conducts heat and can degrade felt prematurely). Ice and water shield membrane is applied at all eaves, valleys, and around penetrations — these are the areas most vulnerable to wind-driven rain. The underlayment serves as your secondary water barrier if any water ever gets past the metal panels.

Step 5: Drip Edge and Flashing Installation

Metal drip edge is installed along all eaves and rakes. This directs water into the gutters and prevents it from wicking back under the panels. Valley flashing (W-shaped metal channels) is installed in all roof valleys. Custom flashing is fabricated and installed around chimneys, skylights, vent pipes, and any other penetrations. For standing seam installations, the flashing work is the most time-consuming and skill-dependent part of the job — it is also where poorly trained installers cut corners.

Step 6: Panel Installation

The metal panels are installed from the eave to the ridge. For standing seam systems, each panel is mechanically seamed or snap-locked to the adjacent panel, creating a continuous, interlocked surface. Panels are attached to the decking via concealed clips that allow for thermal expansion and contraction — metal expands significantly in Myrtle Beach summer heat and contracts in winter. For corrugated systems, panels are fastened with self-tapping screws through the panel face using neoprene washers. Proper screw pattern and torque are critical — over-driving screws is a common mistake that crushes the washer and creates future leak points.

Step 7: Ridge Cap and Trim Installation

Ridge caps are installed along the peak of the roof where the two slopes meet. Ventilated ridge caps allow attic airflow while keeping water out — proper attic ventilation is critical in coastal SC to prevent condensation and mold growth. All trim pieces (gable trim, eave trim, transition flashings) are installed and sealed. On standing seam roofs, all trim connections use butyl tape sealant rather than exposed caulk, which degrades in UV exposure.

Step 8: Final Inspection and Cleanup

The crew performs a detailed final inspection checking every seam, flashing connection, fastener, and trim piece. A magnetic roller is run across the yard and driveway to pick up any dropped screws or metal shavings. All debris is removed and the site is left clean. At WeatherShield, we walk the roof with the homeowner (or provide photos) to document the completed installation before final payment.

How Long Does Metal Roof Installation Take?

Most residential metal roof installations take 2 to 5 days from tear-off to final cleanup. The actual timeline depends on the size and complexity of your roof, the type of metal being installed, and weather conditions.

Roof TypeSimple RooflineComplex Roofline
Corrugated Panels1.5 – 2 days3 – 4 days
Metal Shingles2 – 3 days3 – 4 days
Stone-Coated Steel2 – 3 days3 – 5 days
Standing Seam2 – 3 days4 – 5 days

Factors that extend the timeline:

  • Weather delays: Metal panels cannot be safely installed in rain, strong winds (above 25 mph), or lightning. Myrtle Beach afternoon thunderstorms in summer can cause half-day delays.
  • Decking repairs: Extensive rot or damage adds half a day to a full day.
  • Multi-story homes: Heights above 2 stories require additional safety setup time.
  • Custom fabrication: Complex flashing and trim work for non-standard penetrations.
  • Material delivery delays: Custom-ordered panels (specific colors or gauges) may have lead times of 2–4 weeks before installation begins.

Why Metal Roofs Excel in Myrtle Beach and Coastal South Carolina

Myrtle Beach and the Grand Strand present some of the toughest conditions for any roofing material: Category 1–4 hurricanes, constant salt air exposure, intense UV radiation, tropical humidity, and dramatic temperature swings. Metal roofing is uniquely suited to handle all of these challenges.

Hurricane and High Wind Performance

Standing seam metal roofs carry wind ratings of 140 to 180 mph, exceeding the minimum requirements for coastal Horry County construction. The interlocking panel system creates a monolithic surface with no exposed edges for wind to catch. During Hurricane Florence (2018) and Hurricane Ian's outer bands (2022), metal roofs in the Myrtle Beach area consistently outperformed shingle roofs, particularly at fastener points and ridge lines where shingle blow-offs are most common.

Salt Air Corrosion Resistance

Salt spray from the Atlantic accelerates corrosion on all metals. However, modern metal roofing systems are engineered for coastal exposure. Galvalume (aluminum-zinc alloy) coated steel panels resist corrosion far better than plain galvanized steel. When topped with a PVDF (Kynar 500) paint finish, these panels maintain their integrity and appearance for 30–40 years even in direct coastal exposure. Aluminum panels offer even better corrosion resistance and are the top choice for oceanfront properties.

Energy Efficiency

Metal roofs reflect a significant portion of solar radiation rather than absorbing it like asphalt shingles. A cool-metal roof with an Energy Star-rated reflective coating can reduce cooling costs by 10 to 25 percent — a meaningful savings in Myrtle Beach where air conditioning runs 7–8 months per year. Over a 40-year roof life, that adds up to $8,000–$15,000 in energy savings at current utility rates.

Insurance Premium Discounts

South Carolina insurance carriers increasingly reward metal roof installations with premium discounts of 10 to 35 percent. The exact discount varies by carrier and depends on the specific wind rating of your system. Standing seam roofs with documented wind uplift testing consistently qualify for the highest discounts. A FORTIFIED Roof designation (available through IBHS) can unlock additional savings. On a coastal SC home paying $3,000–$6,000 per year in homeowner's insurance, a 20% discount saves $600–$1,200 annually — recovering a significant portion of the metal roof investment over its lifetime.

Metal Roof vs Shingles: 30-Year Total Cost Comparison

The upfront cost of a metal roof is 2–3 times higher than asphalt shingles. But roofing cost should be evaluated over the full life of the roof, not just the initial installation. Here is what a 2,000 square foot home actually costs over 30 years with each option:

Cost CategoryArchitectural ShinglesStanding Seam Metal
Initial Installation$10,000 – $16,000$24,000 – $36,000
Replacement at Year 20$14,000 – $22,000$0 (not needed)
Maintenance Over 30 Years$3,000 – $5,000$500 – $1,000
Energy Savings (Cooling)$0 baseline−$6,000 – −$12,000
Insurance Savings (20% disc.)$0 baseline−$12,000 – −$24,000
30-Year Total Cost$27,000 – $43,000$6,500 – $1,000

The bottom line: When you account for the shingle replacement you will need at year 20, plus the ongoing maintenance, higher insurance premiums, and higher energy bills, architectural shingles cost more than metal over a 30-year window in coastal South Carolina. Metal costs more on day one but saves $15,000 to $30,000+ over the life of the roof. For a deeper dive, see our metal roof vs shingles cost comparison.

Coastal South Carolina Metal Roof Requirements

Installing a metal roof in the Myrtle Beach area is not the same as installing one in an inland location. Coastal SC has specific building code requirements and environmental conditions that demand particular materials and methods. Here is what you need to know — and what to ask your contractor about.

PVDF (Kynar 500) Coatings Are Non-Negotiable

For any metal roof within 15 miles of the South Carolina coast, PVDF (polyvinylidene fluoride) coatings are essential. Sold under brand names Kynar 500 and Hylar 5000, PVDF coatings resist salt spray corrosion, UV degradation, and chalking for 30–40 years. Standard polyester paint coatings will chalk, fade, and lose corrosion protection within 8–15 years in coastal exposure. The cost difference is $1–$2 per square foot — a small premium for decades of additional protection.

Concealed Fasteners for Primary Structures

Exposed fastener systems (corrugated and R-panel) use screws that penetrate through the face of the panel. Each screw penetration is a potential corrosion and leak point. In coastal salt air, the rubber EPDM washers that seal these penetrations degrade faster, the screw heads themselves can corrode (even stainless steel is not immune to galvanic corrosion when in contact with dissimilar metals), and thermal expansion causes screws to loosen over time. For primary residences, concealed fastener systems (standing seam, metal shingles) are strongly recommended.

Stainless Steel and Approved Fastener Hardware

All fasteners, clips, and attachment hardware should be stainless steel (304 or 316 grade) for coastal installations. Standard galvanized fasteners can corrode within 5–10 years in salt air. 316 stainless steel is preferred for properties within 1,500 feet of the ocean. This is not an area to save money — a $200 upgrade to stainless steel fasteners protects a $30,000+ roof investment.

Wind Uplift Testing and Documentation

Horry County and most Grand Strand municipalities require roofing systems installed in the coastal wind zone to meet specific wind uplift standards. Your contractor should provide documentation showing the installed system's tested wind rating meets or exceeds local code requirements. This documentation is also required by most insurance carriers to qualify for metal roof discounts. Ask for the manufacturer's test report (typically ASTM E1592 or UL 580) and confirm the installation method matches the tested configuration.

Insurance Savings With a Metal Roof in Coastal SC

Homeowner's insurance in coastal South Carolina is expensive — many Grand Strand homeowners pay $3,000 to $8,000 per year. A metal roof is one of the most effective ways to lower that premium because it directly addresses the insurer's biggest risk: wind damage claims.

Typical Insurance Discounts for Metal Roofs

Roof TypeTypical DiscountAnnual Savings ($4,000 Premium)30-Year Savings
Standard Shingles0% (baseline)$0$0
Impact-Resistant Shingles5% – 15%$200 – $600$6,000 – $18,000
Corrugated Metal10% – 20%$400 – $800$12,000 – $24,000
Standing Seam Metal15% – 30%$600 – $1,200$18,000 – $36,000
Standing Seam + FORTIFIED25% – 35%$1,000 – $1,400$30,000 – $42,000

How to maximize your insurance savings:

  1. Choose standing seam with a documented wind rating. The higher the tested wind speed, the better the discount.
  2. Get FORTIFIED Roof designation. This third-party certification from the Insurance Institute for Business & Home Safety verifies your roof meets enhanced wind resistance standards. The evaluation adds $500–$1,500 to your project but can unlock the maximum insurance discount.
  3. Provide your insurer with documentation. Submit the manufacturer's wind test report, the contractor's certificate of completion, and any FORTIFIED certification. Do not assume your insurer will automatically apply the discount — request it in writing.
  4. Shop your policy after installation. Some carriers offer better metal roof discounts than others. A new metal roof is a good time to get competing quotes from 3–4 carriers.

Frequently Asked Questions

How much does it cost to install a metal roof on a 2,000 sq ft house?

For a 2,000 square foot home in the Myrtle Beach area, a metal roof installation typically costs $20,000 to $40,000 depending on the metal type. Corrugated steel panels start around $20,000, metal shingles run $24,000 to $32,000, and standing seam metal costs $28,000 to $40,000. These prices include materials, labor, underlayment, trim, and flashing.

How long does it take to install a metal roof?

Most residential metal roof installations take 2 to 5 days. A straightforward ranch-style home with a simple roofline can be completed in 2–3 days. Complex roofs with multiple valleys, dormers, or steep pitches may take 4–5 days. Weather delays, decking repairs, and material delivery can extend the timeline.

Is a metal roof worth the extra cost over shingles?

Yes, for most homeowners in coastal South Carolina. While a metal roof costs 2–3 times more upfront, the 30-year total cost is often lower. A metal roof lasts 40–70 years versus 15–25 for shingles, meaning you avoid at least one full replacement cycle. Add insurance discounts of up to 35%, energy savings of 10–25% on cooling, and zero maintenance costs, and metal typically wins the long-term comparison.

Can you install a metal roof over existing shingles?

Yes, in many cases a metal roof can be installed over one layer of existing asphalt shingles, saving $1,000–$3,000 in tear-off costs. However, in coastal SC where moisture and hurricane winds are factors, a full tear-off with decking inspection is usually the better choice. The existing decking cannot be inspected for rot or damage if you install over, and local building codes must allow it.

What type of metal roof is best for hurricanes?

Standing seam metal roofing is the best choice for hurricane zones. Its concealed fastener system means no exposed screws or nails that can back out in high winds. Standing seam panels interlock continuously along the seam, creating a monolithic surface that resists wind uplift. Many standing seam systems are rated for 140 to 180 mph wind speeds.

Do metal roofs lower insurance rates in South Carolina?

Yes. Many South Carolina insurance carriers offer discounts of 10 to 35 percent for metal roofing, particularly standing seam systems with high wind ratings. A FORTIFIED roof designation can unlock the largest discounts. On a coastal SC home paying $4,000/year in insurance, a 20% discount saves $800 annually — $24,000 over the roof's lifetime.

What metal roof coating is best for coastal salt air?

PVDF (polyvinylidene fluoride) coatings, sold under brand names Kynar 500 and Hylar 5000, are the gold standard for coastal metal roofs. PVDF coatings resist salt spray corrosion, UV degradation, and chalking for 30–40 years. They cost $1–$2 more per square foot than standard polyester coatings but are essential for any metal roof within 15 miles of the coast.
