The occurrence of standing water on your roof deck or balcony-- or "ponding,"
as it's called-- is not only an indication that something could be
wrong with your deck, it could aggravate existing water intrusion issues,
as well. Below, we examine this common issue, its causes, and why it should
be remedied as soon as possible.
What Causes Ponding?
Ponding can be caused by several issues. One of them is improper installation
of your roof deck. Because rain is always a possibility, roof deck surfaces
need to be equipped with a subtle incline that allows gravity to pull
water off the deck when there is precipitation. When this incline is not
properly implemented, ponding can occur within the deck's perimeter.
Even when roof decks are properly installed, ponding can still occur if
the deck begins to experience sag. In very old roof decks, a warping of
the surface can occur over time—but in decks experiencing internal
moisture intrusion, sagging can occur much earlier and compromise the
The Effects Of Ponding
Most property owners notice ponding because it tends to leave ugly stains
on the surface of their roof decks when the water finally dries. However,
this effect is only cosmetic and serious ponding can pose an even greater
threat to your roof deck.
If your deck is experiencing ponding, it means it is experiencing prolonged
exposure to water. This exposure means that the eventual wear and tear
of your deck sealant can become a major issue faster. Once moisture has
infiltrated the inner structure of your deck, structural damage is possible--
especially when ponding continues to supply a steady supply of water.
