Water Damage: Addressing ponding water on a heavily penetrated low slope roof

There are essentially two ways water leaves a roof: positive drainage or evaporation. When neither can occur quickly enough, the result is ponding water.

Ponding water is defined as any water remaining on a roof 48 hours after a rain. Most commonly occurring on low-slope commercial roofs, ponding water can result from poor building/roof design, poor drainage and pockets forming on the roof after a building or substrate settles.
