Continue reading to learn the answers to these questions.

“Ponding” Defined

The word “ponding” refers to a pool of water on flat roofs that remains visible for at least two days after rain.

Directly following rainfall, it’s common to see a little water on your flat roof.

If it stays there and doesn’t drain after a short period, however, you’re dealing with a ponding water problem.

Ponding is a significant issue because it can cause considerable damage to your roof.

When water is allowed to it for long periods, it can cause water damage.

Water damage begins by affecting your roof’s structural integrity but can eventually spread to damaging other parts of your home.

Common Causes of Ponding Water

There are many potential reasons for ponding water on flat roofs.

Problems with the roof’s draining system is a common problem.

Drainage system issues can range from improperly installed drains to clogs or structural damage.

Poor building design can also be blamed if ponding water is a persistent issue in new buildings.

Crushed insulation or damage from natural weather events can cause low spots that allow pockets of ponding water, also.

Even excessive heat could play a role in why water is pooling on your roof.

Common Cures for Ponding Water

When you notice water ponding on your roof, you must solve the problem as soon as possible.

The longer rain is allowed to sit, the more significant water damage has the potential to be.

A few of the most common cures for ponding water include:

  • Flushing the drain system
  • Fixing low spots
  • Adding additional drain lines
  • Re-pitching the roof
  • Replace the roof membrane
  • Fixing the insulation

The best way to figure out the cause and cure of ponding water on a flat roof is to call a professional roofer.

They can help diagnose the issue and repair the problem, so it doesn’t continue happening.
