Myrtle Beach Roof Repair Cost & Common Problems

Myrtle Beach and Horry County enforce the 2018 International Residential Code with local coastal amendments. Permits are processed through the City of Myrtle Beach Construction Services for properties inside city limits and through Horry County for unincorporated areas including most of the beach-adjacent neighborhoods outside the Myrtle Beach proper. Residential reroof permit fees run $175 to $400 depending on roof area and value.

The coastal location places Myrtle Beach in a stricter wind exposure category than inland South Carolina. The applicable design wind speed is 140 mph for most of the metro, which constrains product selection - roofing materials must have wind warranties rated for that speed, and most asphalt shingle products require enhanced nailing patterns (six-nail rather than the four-nail standard). Coastal-rated underlayment and stainless steel or hot-dipped galvanized fasteners are common requirements.

South Carolina's residential builder licensing requirement applies in Myrtle Beach. The Department of Labor, Licensing and Regulation (LLR) requires a Residential Builder license for any project over $5,000, which captures essentially all full reroofs. Verification is through the LLR website.

Myrtle Beach sits in one of the more hurricane-active stretches of the Atlantic coast, with significant historical impacts including Hurricane Hugo (1989), Hurricane Florence (2018), and Hurricane Isaias (2020). The most recent significant event was Hurricane Idalia in August 2023, which brought tropical-storm winds to the Grand Strand region. Hurricane Helene in September 2024, while making landfall in the Big Bend area of Florida, produced wind effects across the South Carolina coast that included scattered roof damage.

The cumulative weather pattern in Myrtle Beach produces a different roofing market dynamic than inland South Carolina. The Grand Strand region experiences hurricane-related claim waves followed by quieter intervals, rather than the more uniform pattern of inland markets. After Hurricane Florence in 2018, the regional roofing capacity was overwhelmed for nearly two years; the post-storm patterns since then have been more manageable but still produce capacity stress when major events occur.

The other factor specific to Myrtle Beach is the tourism economy and the high concentration of vacation rentals and second homes. Many of the homes in the metro are not primary residences for their owners, which produces specific insurance and project timing considerations. Vacation rental owners often delay reroof work to avoid disrupting rental income, which can extend the time between insurance settlement and actual repair work. Insurance carriers serving short-term rental properties have separate underwriting standards than primary-residence policies, and roof condition is a more significant factor in their decisions.

Salt air corrosion is the other recurring factor. The Grand Strand's beach proximity produces meaningful corrosion of exposed fasteners, flashing materials, and metal components. Stainless steel fasteners, copper flashing on visible architectural details, and aluminum that has been properly anodized are the appropriate material specifications. Standard galvanized hardware fails noticeably faster here than in inland markets.
