Roofing problems are common, especially on flat roofs. One of the most common issues that commercial flat roofs face is ponding water. Ponding water occurs when water accumulates on the surface of the roof for more than 48 hours after rainfall, and it can have serious consequences if left unaddressed. In this article, we will discuss how to spot and stop ponding water on a roof and the long-term effects of ignoring it. 

How to Spot Ponding Water on a Roof 

The first step in addressing ponding water on your commercial flat roof is to spot it. You can easily identify ponding water by looking for standing water on the roof after rainfall. However, sometimes ponding water is not visible to the naked eye. In such cases, you can look for water stains or discoloration on the roof. Another way to spot ponding water is to look for debris that has accumulated in one spot, as it may be blocking the drainage system. 

What are the Long-Term Effects of Ignoring Ponding Water on a Roof? 

Ignoring ponding water on your commercial flat roof can have long-term effects. One of the most common consequences of ponding water is roof leaks, which can cause significant damage to the roof deck and insulation. Ponding water can also damage the roofing membrane, leading to cracks and tears, which will eventually require costly repairs or replacement. In addition, ponding water can cause mold and mildew growth, which can be dangerous to the health of the building's occupants. 

How to Stop Ponding Water on a Roof 

Stopping ponding water on a commercial flat roof requires proper drainage. One of the most effective ways to achieve proper drainage is to install a tapered insulation system. This system will slope the roof towards the drainage system, ensuring that water flows freely off the roof. Another way to address ponding water is to install drains or scuppers that will allow water to exit the roof. 

Ponding water on a commercial flat roof is a serious issue that should be addressed as soon as possible. Ignoring it can lead to significant damage to the roof and the building's occupants.
