About
Cornerstone Construction holds GAF certification — a manufacturer credential that signals adherence to installation standards relevant to both residential and light commercial roofing projects across Greenville and Upstate South Carolina. Operating since 2017, the company serves commercial and residential properties throughout Greenville, Simpsonville, Greer, Easley, Mauldin, and Travelers Rest, giving facility managers and property owners across the Upstate region a locally rooted contractor option. For commercial clients managing retail centers, office buildings, multifamily properties, or mixed-use developments, Cornerstone Construction offers roof replacement, roof repair, and new roof installation services. In the Greenville market, where high summer humidity, frequent thunderstorms, and seasonal temperature swings accelerate membrane and surface wear, timely repair and replacement cycles are critical to protecting building envelopes and avoiding costly interior damage. The company's team is licensed and insured, and its dual-office presence — with locations in Greenville and Travelers Rest — positions it to respond to project needs across a broad service footprint. While the company's website messaging leans heavily toward residential homeowner language, commercial property stakeholders evaluating light commercial roofing needs such as modified bitumen systems, metal roofing, low-slope coating applications, or EPDM membrane work on smaller commercial structures may find Cornerstone's GAF certification and regional experience worth exploring. Additional exterior services including gutter installation and siding replacement round out the company's offering for property managers seeking a single-source contractor for exterior envelope work. Facility managers should confirm specific commercial membrane system capabilities, insurance limits, and project scale directly with the contractor before engaging for larger commercial scopes.
