Top Tools to Remove Ponding Water on a Flat Roof

Top Tools to Remove Ponding Water on a Flat Roof

Ponding water is detrimental when allowed to sit for a period of time on a flat commercial roof. This means it’s up to you to use various tools to remove the water. It can improve drainage and ensure you don’t experience problems down the road.

Knowing about the tools will make it easier to choose what’s best for your roof. Pros and cons exist for all of the tools.

Ponding Pumps

One of the first tools available to you are ponding pumps. These are simple water pumps that are placed throughout the flat roof where there are low-lying areas. A hose attaches to the pump so the water is able to be pumped off of the roof and to the ground below.

These are relatively affordable, though depending on the size of the roof, several may be required. Various models are available as well, including ones that are solar-powered. This makes it cheaper to keep operating. The downside to the ponding pumps is that it’s not a permanent solution. The low-lying areas still exist and therefore the pumps would have to be in place in an ongoing fashion to take care of the standing water.

Push Brooms

Push brooms are often used to remove small amounts of ponding water from a flat commercial roof. This is certainly a low-budget tool, but it’s not very effective. For one, it’s not something that will take care of the ponding automatically. You would have to get up on the roof after every rainfall to remove the water manually, and this will be a time-consuming project.

If you add a water alarm to the roof, you will be notified when there is water to tell you that you need to go up and sweep the water off. However, even with an alarm, it’s not a sufficient enough tool to truly make an impact.

Tapered Insulation System

Another tool that can be used for ponding water is a tapered insulation system. Whether a building is part of new construction or it is being re-roofed, this is an option to explore so that there is a positive slope to the roof.

A benefit to this kind of system is that it adds to the thermal resistance and therefore improves overall insulation of the building. The primary downside, however, is that the construction of such a system is expensive and many commercial property owners don’t want to spend the money when they are already paying for a new roof to be constructed.

Roof Coating

It’s also possible to use a roof coating as a tool to remove the ponding water problem entirely. The coating fills in the low-lying areas so there is nowhere for water to puddle across the roof. This is a cost-effective method and dries quickly, allowing you to have the solution in place within hours.

With the right roof coating, you gain a positive slope to ensure that water runs off on its own. It’s one less thing for you to worry about because you won’t need to visually inspect the roof every time it rains.

You have plenty of tools to choose from when you experience ponding water on your roof. Some of the tools are more affordable and more effective than others. Much of it is going to depend on the size of your commercial roof as well as the budget you have to take care of the problem.

In the end, you want a tool that will take care of the problem once and for all so you don’t have to constantly wonder whether the water exists and whether it is damaging your roof.
