Water is a constant source of worry for any homeowner. It is the single most destructive element, and just a few drops can cause major problems. For commercial building owners, making sure that the roof, although seemingly flat, has an adequate slope allowing for water to drain from the roof should be the top priority. Low slope commercial roofs are particularly susceptible to ponding water, and should be the first thing that managers and owners keep an eye on.
Negative consequences of ponding water on your roof
No matter the type of roof you have or the materials used, ponding water is a threat to all of us. You may not think much of a few puddles on your roof, as long as it’s not penetrating the system into your building, is something to be concerned about. But, any water allowed to sit on your roof for more than 48 hours is considered “ponding water.” If your roof has been designed, installed, and properly maintained over time, chances are you will not have problems with ponding water. However, many neglected buildings and rooftops will have deteriorated over time, and may be showing the effects of water ponding on the roof for long periods of time.
It may not look like much, but ponding water on your roof can add a significant amount of weight to your roofing system. The longer it is allowed to sit and weigh down on your roof deck, the more the structure of your roof will start to buckle and sag under the added pressure. The deformation of the deck structure will slowly grow, and allow for more and more water to gather, adding more and more weight until your roof simply gives up and collapses.
One little puddle can compromise the structural integrity of your roofing system
During the Colorado winter, ponding water is likely to freeze, thaw, and freeze again. This movement will act like sandpaper on your roof, slowly sanding away at the EPDM or TPO membrane of your commercial roof, causing serious physical damage. Similarly, dirt, debris, and other objects that gather in ponding water can cause damage to your roof membrane, weakening the whole structure.
Ponding water can also lead to the growth of fungus and algae that can add to the damage. This occurs when the ponding water has been left unattended for long periods of time.
