How Ponding Water Causes Costly Water Damage on Commercial Roofs

When water does not drain properly off a roof, it can collect in an area, and this action is known as "ponding." Ponding water on the roof of a commercial building can be the root cause of significant water damage, posing severe threats to the structure and contents of your facility. Whether caused by clogged gutters, poor roof design, or heavy rainfall, standing water on a flat or low-slope roof is a problem that should be addressed quickly.

Ponding Roof Water Creates Structural Stress and Material Degradation

Ponding water adds considerable weight to your roof. Over time, this water weight can cause structural stress, potentially leading to dangerous sagging or even a partial collapse. Commercial roofs are constructed to withstand weather conditions but not to support the extra burden of stagnant water for extended periods. The added pressure can also cause roofing materials to deteriorate faster, especially those not designed for constant moisture exposure. When these materials break down due to the extra weight, your roof becomes more vulnerable to leaks and other damage.

Unaddressed Ponding Results in an Increased Risk of Leaks and Water Intrusion

Water damage to commercial roofs caused by ponding water often announces its presence with leaks. Water can seep into a building through weakened membranes, joints, or seams, damaging insulation, electrical systems, and interior finishes. Once water penetrates these vulnerable areas, repairing them can be challenging and costly. Additionally, water inside a building can lead to further complications, such as damaged ceilings, walls, stock, and equipment.

Mold Growth Often Accompanies Ponding Damage

Standing water on your roof creates an ideal environment for mold and mildew to thrive. When water is allowed to pool, it can seep into the building materials, creating persistent moisture problems that are difficult to address. Mold spores can spread throughout your facility, resulting in subpar indoor air quality and potential health issues for your occupants.

Avoid a Shortened Roof Lifespan and Increased Repair Costs

Ponding water accelerates the aging process of roofing materials, leading to shorter service life for your roof. This premature aging means more frequent repairs and an early roof replacement. Immediately addressing ponding issues can help you avoid these costly consequences. Proper roof maintenance should include:

  • Clearing gutters and downspouts to improve drainage and prevent water buildup.
  • Inspecting and resealing roof penetrations such as vents, chimneys, and skylights to prevent leaks.
  • Repairing low spots or areas prone to ponding by improving slope or adding drainage solutions.
  • Replacing damaged or worn roofing materials before they compromise the entire structure.

These proactive measures can extend your roof’s life and reduce the need for expensive repairs or premature replacement.
