What Is Ponding And How Is It Destroying Your Commercial Roofin

Posted on: 3 April 2017


Regardless of the type of roof your business has, ponding is a serious problem that could lead to irreparable damage. Ponding occurs when your roof has standing water on its surface. If you have noticed water remaining on your roof for days after a storm, here is what you need to know.  

What Damage Can Occur?

When water pools up on your roof, it increases the weight of the roof and places a strain on the building. If your building is not structurally sound, the excess weight could lead to a collapse. Not only does this put your life and those of your customers and employees at risk, but it can cause widespread damage to the interior of your business.  

Ponding can also increase the likelihood that you will experience a leak. The water can cause parts of your roof to weaken, which allows the water to enter. Leaking water could mean your business is more vulnerable to mold and mildew.  

The standing water on your roof can even lead to increased ultraviolet degradation of your roof. When the sunlight hits the water on the roof, it can intensify the heat from it and speed up the deterioration of the roofing materials.  

What Can You Do?

One of the first steps you can take to end the ponding is to check your gutters and downspouts. Ideally, your roof was installed with a slight pitch that would allow the water to trickle down the roofing and fill the gutters. The downspouts would then push the water away from the foundation of your business. If your gutters or downspouts are clogged or otherwise damaged, the drainage might not occur.  

Another possible solution could lie in the insulation used beneath the roofing. Over time, it is possible for the insulation to become crushed. Crushed insulation leads to a flattened roof, which means the water cannot drain to the gutters.  

Simply replacing the areas that have crushed insulation might be the solution. Call in your roofing contractor to check the insulation. You can place plaster in the areas where the water is pooling up if you are concerned the roofing will be damaged before your roofing appointment.  

Your roofing contractor can assess your business's roof to determine if there are other issues that are causing ponding. Once the problem has been identified, a roofer like TRM ROOFING can offer solutions for repairing the roof and preventing future ponding.
