What is ponding water – an accumulation of water that settles on the roof for more than 48 hours without draining or evaporating. What’s wrong with a little water on the roof – it’s meant to get wet, isn’t it? It may seem like a small amount of water, but it can quickly have disastrous effects on your commercial roof. Commercial roofing materials are designed to shed rain water but are NOT designed to withstand ponding water for long periods of time. Ponding water will rapidly deteriorate your roofing membrane causing leaks and sagging, which in turn creates more ponding water. Your roof is suddenly bearing more weight thanks to the ponding water. After a while, the excessive ponding water can cause the roof to collapse. The larger the commercial building, the greater the risk of ponding water on the roof.
Most common reasons for ponding water:
Poor roof drainage design
Obstructed roof drainage
Poor design or structural defect issues
Saturated roof insulation caused by a roof leak left unrepaired
Compressed roof insulation caused by a roof leak
Drains and scuppers are located too high for water to drain
Poorly done repairs causing a hump near drains
Damaging effects of ponding water:
Rotted roofing membrane
Algae and vegetation growth
Buildup of dirt, debris, and contaminants
Destruction of reflective coatings
Premature roof failure
It’s important to note that a roof warranty is voided if ponding water has occurred for longer than 48 hours and not repaired.
