Is There Ponding on Your Flat Roof_ Here’s How You Can Fix It

December 12, 2022

Ponding water is simply water that collects and stands on a flat roof. This can happen for several reasons, including poor drainage, a clogged gutter, or simply because the roof isn’t sloped enough to allow the water to run off.

Whatever the cause, ponding water can be a serious problem. It can lead to leaks, premature roof deterioration, and even collapse.

So What Can You Do to Fix Ponding Water on Your Flat Roof?

Here are a few options:

1. Install a Drainage System

One of the best ways to fix ponding water is to install a drainage system. This can be as simple as installing additional gutters and downspouts to help move the water off the roof or as complex as installing a complete drainage system with underground pipes.

2. Reslope the Roof

If your roof isn’t sloped enough, ponding water will inevitably collect. One way to fix this is to slope the roof. This can be done by adding additional insulation or installing a new roof deck.

3. Add a Membrane

Another option is to add a membrane to the roof. This can be a waterproofing membrane or an impenetrable barrier. The membrane will prevent water from seeping into the roof and help keep the ponding water from causing damage.

4. Repair Any Leaks

If ponding water is already causing leaks, it’s important to repair them as soon as possible. Leaks can quickly lead to further damage, so it’s best to fix them before they worsen.

5. Remove the Ponding Water

If all else fails, you can always try to remove the ponding water from the roof. This can be done with a pump or simply scooping it up and removing it from the roof.

What Happens If You Ignore It?

Ponding on a flat roof is a serious problem that should not be ignored. If left untreated, ponding water can cause serious damage to the roofing materials and even the structure of the building. Ponding water can also create an ideal environment for the growth of mold and mildew, which can cause health problems for the occupants of the building.
