Commercial Roofing in South Carolina: A Business Owner Guide

By Dubya Roofing & Gutters | November 06, 2025 | 8 min read

Commercial roofing in South Carolina presents different challenges and opportunities than residential roofing. From retail stores and office buildings to warehouses and churches, each commercial property has unique roofing requirements. Here is what SC business owners and property managers need to know about protecting their commercial investments.

Common Commercial Roofing Systems in SC

TPO (Thermoplastic Polyolefin)

TPO is the most popular commercial roofing membrane in South Carolina. It offers excellent heat reflectivity, reducing cooling costs in our intense summers. TPO membranes are heat-welded at the seams for watertight performance and resist UV degradation, chemicals, and punctures. Lifespan: 20 to 30 years. Cost: 5 to 8 dollars per square foot installed.

EPDM Rubber Roofing

EPDM is a durable synthetic rubber membrane popular for its low cost and proven track record. It handles extreme temperature swings well and is easy to repair. However, black EPDM absorbs heat, making white TPO or PVC better choices for energy efficiency in SC. Lifespan: 20 to 25 years. Cost: 4 to 7 dollars per square foot.

Metal Roofing

Standing seam metal roofing is increasingly popular for commercial properties that need maximum longevity and storm resistance. Metal excels on churches, retail buildings, and any structure where a 50-plus year roof makes economic sense. Cost: 8 to 14 dollars per square foot installed.

Built-Up Roofing (BUR)

Built-up roofing uses multiple layers of bitumen and reinforcing fabric to create a thick, durable membrane. BUR is one of the oldest commercial roofing systems and remains popular for its proven waterproofing ability. It handles foot traffic well, making it suitable for roofs with frequent maintenance access. Lifespan: 15 to 30 years.

Key Differences from Residential Roofing

Commercial roofs are typically flat or low-slope, requiring different materials and drainage solutions. They often support HVAC equipment, solar panels, and other rooftop infrastructure. Building codes for commercial structures are more stringent. And the financial impact of a roof failure on a business, including lost inventory, interrupted operations, and liability, makes preventive maintenance even more critical.

Commercial Roof Maintenance Programs

We offer annual maintenance programs for commercial properties that include bi-annual inspections, gutter and drain cleaning, sealant touch-ups, and minor repairs. A maintenance program costs a fraction of emergency repairs and can extend your commercial roof lifespan by 5 to 10 years.
