How to counter water stagnation on a flat roof?

Whether it is a residential roof, or a commercial or industrial one, you must quickly deal with standing water issues on your roof. But when must one intervene actually? If, 48 hours after a rainfall, there are still one or several pools of collected water, you need to act; and while a simple repair is often sufficient, a water stagnation problem that has not been dealt with can lead to the replacement of a roof because of damages that may result from it.

What are the causes of standing water on a roof?

It can simply be that a drain is clogged with various debris such as leaves or small branches, which prevents water from properly draining; in this case, the problem will be solved once the drain is cleaned out. Another reason could be due to the wrong angle of the roof, because even if your building has a flat roof, a minimum gradient is always necessary to allow for good water evacuation! Our roofers specialized in flat roofs will however be able to solve this problem by correcting your roof pitch.

What are the possible consequences of water collecting on a roof?

First, you might have problems obtaining your warranty service in case of damage to the roof membrane, because these damages are a direct result of the standing water problem, and not the membrane. In addition, water collecting on your roof will lead to additional weight that could also cause roof damage and, if there was water seepage on top of that, could lead to damage to the structure of your building!
