Water Ponding VS. Snow Load

The vast majority of building failures are weather related.  Most are caused by the weight of snow, but water ponding continues to be a major concern.

Snow doesn’t move (much), it generally stays where it  falls, BUT water is a different problem because it always moves & collects in low the spots.   

Run-a-way roof ponding starts with water collecting in a low spot, centralizing a load usually spread across the surrounding area.  This in turn deflects the supporting joists/purlins and leads to more water running into an increasingly deeper pond.  As the deflection increases, water from a larger and larger area runs toward one small roof area and ultimately causes a structural failure, or at least overwhelms HVAC curbing and other penetrations letting enormous amounts of water pour inside. Either way it’s a huge mess and expense that can be completely avoided.

Prevent a run-away roof loading cycle from overwhelming your business by adding Roof Deflection Monitoring as a predictive maintenance program.   

Simply put – “knowing when and where to act” saves time & money and helps you avoid a costly business disruption.
