Flat Roofing in Coastal Georgia: Unique Challenges
Flat roofs dominate Coastal Georgia's commercial landscape, from Savannah's port facilities to modern office complexes and retail centers. These systems face unique challenges in our humid subtropical climate: intense UV exposure, thermal cycling, hurricane-force winds, and persistent moisture that can devastate inadequately maintained roofing systems.
Unlike sloped roofs that shed water naturally, flat roofs depend entirely on proper drainage and membrane integrity for protection. A small leak or drainage problem can quickly escalate into catastrophic failure, causing hundreds of thousands in business interruption, inventory loss, and structural damage.
This comprehensive guide provides property owners, facility managers, and maintenance professionals with the knowledge needed to protect flat roof investments. From understanding different membrane systems to implementing cost-effective maintenance programs, these strategies ensure optimal performance and maximum service life in our challenging coastal environment.
