When it rains, you should take the time to look up at your roof and see if water is falling from the roof as it is supposed to, or whether water is pooling or puddling on the roof. If water is pooling or puddling, you need to call in a commercial roofing contractor to fix the drainage issues you are experiencing. Puddling water can lead to multiple roof issues if not properly addressed. Here are some of those issues. 

Leaks

One of the biggest issues that puddling or pooling water on a commercial roof can cause is a leak. As water sits on your roof, it can damage your roofing materials and shorten their lifespan. Water can then penetrate through one or more layers of roofing, causing a leak. A roof leak can damage items you have stored inside of your commercial building, and be costly to repair, so you want to prevent leaks as much as you can. 

Attracts Insects and Pests 

Another reason why you want to quickly call in a commercial roofing contractor if you see water puddling on your roof is that sitting water can attract insects and pests. Pests can cause a significant amount of damage to your roof, and they may go from the roof into your building, causing damage to things such as your insulation and electrical wiring. 

Algae, Mildew, or Mold Can Grow If Moisture is Present

One of the lesser-known reasons why you never want water pooling on your commercial roof is because water can lead to algae, mildew, or mold. Algae, mildew, and mold can all quickly spread on a damp roof, and cause significant damage to your roofing materials. If you notice water pooling, or you notice one of these items growing on your roof, you should call in a commercial roofing contractor quickly. 

Collapsing Roof

The final reason why you should call in a commercial roofing contractor if you see water pooling on your roof is that pooling water can lead to a roof collapse if the issue is not addressed. Pooling water can weigh on your roof, and if a lot of weight sits on the roof, it can start to sag, sink in, or even collapse. This can affect the entire structure of your building, yet is completely avoidable simply by ensuring water drains from your roof. 

Puddling or pooling water is never something you want to see on your commercial roof, as it can lead to a lot of different problems. If water is not falling off of your commercial roof as it should, you need to call in a commercial roofing contractor. They can inspect the roof, determine why water is pooling, and work to fix the issue before larger problems form due to the sitting water.
