Why is Water Ponding on my Flat Roof?

Clogged Drains

Water ponding on a flat roof may be caused by a clogged drain. In fact, if leaves or debris obstruct the drain, water will not be able to flow out properly. Simply cleaning the area will allow water to be cleared.

Damaged or Aging Membrane

A membrane that is damaged, aged, cracked, or incorrectly installed can cause water to accumulate on a flat roof.
