commercial flat roofing pooling

Roof pooling occurs when, after a period of rain, water accumulates on the roofing surface because for some reason the water is unable to drain. Pitched roofs having slopes, the problem affects them only if any of the roof’s slopes starts sagging, pooling being a more common issue on flat roofs. In the case of flat roofs constructed from water-resistant materials, ponding water does not pose an imminent threat, but even these materials can get weakened and damaged if the exposure to excessive moisture is too prolonged. Here are some more things that you should know about the issue:

  • The most frequent cause: an inefficient draining system – gutters and downspouts that are clogged, otherwise damaged or improperly installed fail to channel water away from the roof, allowing water to gather on the roof if the surface is uneven;
  • Another frequent cause: an uneven roof surface – roof surfaces that have developed pool-like depressions are more prone developing water accumulations;
  • The remedy – the first thing that you should pay attention to is the gutter system. The best way to prevent roof pooling is to make sure that the gutter pipes and the downspouts are clean and free from damage. In the next phase, you should have a look at the roof surface itself to see whether it needs any repairs or straightening.
