Flat roofs and ponding problems

If your commercial or industrial property has a flat roof, one of the most common problems to look out for is ponding. Ponding occurs when rainwater collects on the roof, in a slight structural dip. The rainwater can then no longer drain away from the roof into the gutters, and so it stays on the roof, creating standing water. This can be a big issue for a variety of reasons, including:

  • Additional load- your flat roof wasn’t designed to support an increased weight load, which is what standing water will cause. Moreover, this weight load will be centred in certain pockets, causing increased pressure in different parts of the roof. This can lead to problems with structural integrity.
  • Freezing water- at this time of year, we could yet still experience more snow and freezing temperatures. Standing water on your roof could then freeze. This will increase the weight of the water and lead to more sagging, which will result in even more standing water! Continuing the cycle.
  • Water ingress- if your roof is damaged with a small hole or tear, the damage from the water ingress will be much greater, because of the large amount of standing water that will enter your building.

Appropriate drainage, clear gutters, and the right roof gradient are essential for keeping your flat roof free of standing water. For professional support to resolve your ponding issues, get in touch with the professionals today, here at JMS Roofing.
