What is Ponding Water and Why is it a Problem?

Ponding water occurs when water remains on a flat roof for 48 hours or longer, leading to the formation of a "pond" on the surface. This is an issue that should not be taken lightly, as ponding water can cause significant damage to your roof and the building structure.

Here's why ponding water is problematic:

1. Damage to Roof Surface and Roofing Membrane: Ponding water can deteriorate your roofing membrane and cause cracking and mineral loss. This is because the constant movement of water can scrub away the protective layers of your roof, leaving it vulnerable to leaks and further damage.
2. Increased Risk of Leaks: Prolonged exposure to ponding water can weaken your roofing membrane, making it more susceptible to leaks. Leaks can cause damage not only to the roof but also to the building's interior, leading to costly repairs and potential health risks due to mold and mildew growth.
3. Structural Damage: In extreme cases, ponding water can add significant weight to your flat roof, leading to sagging, deformation, or even collapse.
4. Shortened Roof Lifespan: The ongoing presence of ponding water can considerably reduce your flat roof's lifespan, resulting in more frequent repairs or replacements.

For commercial property managers, addressing ponding water is crucial to improving efficiency and preventing damage across multiple locations. In fact, 45.1% of property managers have expressed a desire to improve efficiency in their operations, making it vital to tackle any roofing issues that may arise.

Now that we know what ponding water is and why it's an issue, let's debunk some common misconceptions about flat roofs.

Flat Roofs: Common Misconceptions

A well-engineered flat roof should not have issues with ponding water. This leads us to a common misconception about flat roofs – that they are entirely flat. In reality, they are not.

Flat roofs are designed with a slight slope to facilitate proper drainage of rainwater, preventing the pooling of water on the surface. Portland's average annual rainfall is 36 inches, making it essential for flat roofs in the area to have effective water drainage systems. When constructed and maintained correctly, a flat roof should not have ponding water issues.

Now that we've clarified this misconception, let's explore the causes of ponding water on flat roofs. Understanding these causes is crucial for finding the right solutions to prevent and address this problem.

Causes of Ponding Water

There are several factors that can contribute to ponding water on a flat roof. By identifying the root cause of the problem, you can take appropriate action to resolve the issue and prevent it from recurring. Here are some common causes of ponding water on flat roofs:

1. Insufficient Slope: As mentioned earlier, a properly engineered flat roof should have a slight slope to facilitate water drainage. If the slope is inadequate, water may not drain effectively, leading to ponding.
2. Blocked or Inadequate Drainage: A flat roof's drainage system can become clogged with debris, such as leaves, twigs, and dirt, preventing water from draining as it should. Additionally, if the drainage system is not designed to handle the volume of water generated during heavy rainfall, it can become overwhelmed, resulting in ponding water.
3. Structural Issues or Damage: Over time, the structure of a building can shift or settle, leading to changes in the roof's slope and creating low spots where water can collect. Damage to the roofing membrane or other components of the roof system can also result in ponding water.

Now that we've discussed the causes of ponding water, let's explore some solutions to help you address and prevent this issue on your flat roof.

Solutions to Ponding Water

To address and prevent ponding water on your flat roof, consider the following solutions. These strategies can help protect your investment, extend the life of your roof, and avoid costly damage to your property:

1. Regular Maintenance and Inspection: Regularly inspecting and maintaining your flat roof can help identify and address potential issues before they escalate. Remove debris, such as leaves and twigs, from the roof surface and drainage system to ensure proper water flow. Additionally, inspect the roof membrane for damage and make necessary repairs as needed.
2. Proper Drainage Systems: Ensure that your flat roof has a well-designed and functioning drainage system. This includes installing adequate drains, scuppers, and gutters to handle the volume of water generated during heavy rainfall. Regularly check and clean these components to prevent blockages and ensure efficient water removal.
3. Roof Leveling or Sloping Solutions: If your flat roof has an insufficient slope or has developed low spots due to structural issues, consider leveling or re-sloping the roof to promote proper drainage. This may involve adding tapered insulation or crickets to create the necessary slope or adjusting the roof's structure to address any sagging or deformation.
4. Roof Membrane Options (TPO and EPDM Roofing): The choice of roofing membrane can also play a role in preventing ponding water. TPO (Thermoplastic Olefin) and EPDM (Ethylene Propylene Diene Monomer) roofing membranes are popular options for commercial flat roofs due to their durability, flexibility, and resistance to ponding water. Consult with a qualified flat roof contractor to determine the best membrane option for your specific needs.
