Ponding occurs when your roof lacks adequate slope (minimum 1/4" per foot) or when drains and scuppers are clogged or improperly positioned. In Savannah, where storms dump 2-4 inches in an hour, ponding accelerates membrane degradation, adds structural load, and breeds algae. Solutions include tapered insulation to create slope, additional drains, or scupper repositioning. We assess ponding during free inspections.

In Savannah's coastal climate, EPDM flat roofs last 20–25 years, built-up roofing 15–20 years, and modified bitumen 15–20 years with proper maintenance. The biggest factor in flat roof lifespan is drainage — a well-drained roof with regular maintenance outlasts a neglected one by a decade.

Flat roofs in Savannah need quarterly inspections for ponding water, membrane damage, and debris accumulation. Clear drains and scuppers before storm season (June–November). Inspect seams, flashings, and penetrations after every major storm. Schedule professional inspections twice yearly — catching small issues early prevents costly emergency repairs.
