Standing Water on a Flat Roof

Standing Water on a Flat Roof

Having some standing water on a roof can be so stressful. How much more when the type of roof that you have at the moment  is a flat one.

Occasional minor ponding on a roof doesn’t really create big problems. However, standing water that stays for more than two days can be very problematic for the roof membrane. This is very serious because it can void your roof’s warranty with no excuses.

Ponding (regardless if it’s a major or a minor problem) can deteriorate the roof’s membrane and shorten its expected lifespan. A ponding problem that has been ignore for so long and not being attended to immediately would be a great expense for you in the future.

Generally, no matter what kind of roofing system you have at this very moment, having standing water is just a stress for you as a homeowner .

Possible Damages That Might Happen

Though a small pond on your rooftop may not seem harmful, if left alone, it can cause severe and costly damage to your flat roof. Here are some possible things that might happen.

  • Ponding water can magnify UV rays, which speeds up the damage caused.
  • Due to the ponding water’s weight, your flat roof can experience a sag. This will seriously weaken its quality.
  • Algae and moss formations are common issues that are found in areas where ponding is rampant.
  • Due to the worsening situation that is caused by the algae growth, magnified UV rays, and the weakening of the roof membrane, leaks can become a major issue.
  • As your roofing membrane is weakened, and leaks will start, the structural integrity of your flat roof may become compromised. This results in many risks, including a full or partial collapse. Do not let this happen to you.

 

When is Standing Water Too Much for Your Building

As most commercial building owners and managers are aware, what appears to be a flat roof on a commercial building is not literally flat. The slope of a low-slope roof is very gradual and not noticeable to the eye. In fact, the minimum required slope ratio is usually ¼:12. This means the surface of the roof system will slope, at a minimum of ¼ of an inch (or ¼ of a unit), for every 12 inches (or 12 units) in length.

If a specific building’s roof deck or substrate does not meet the required ¼:12 slopes, there is a chance that your roofing contractor would have into installing a tapered insulation system. This makes a slope and produces a condition called positive drainage. Its purpose is to completely take away any standing or ponding water on the roof membrane. As a way to keep the roof’s warranty, building owners or caretakers must reach out to a professional roofing contractor to eliminate the standing water soonest within the span of 48 hours. This is based on the guidelines by the National Roofing Contractor Association or NRCA.

Remember that you only have at least 48 hours to dry or drain the standing water that is on your flat roof. If not being attended to immediately, your warranty is completely void. This is why you must make it a priority to at least double-check on your flat roof for any size of ponding water that you can find.
