Flat roofs are a common architectural choice for commercial buildings, offering both aesthetic and functional benefits. However, one challenge that often arises with flat roofs is ponding water. This issue, if not addressed promptly, can lead to significant damage, including leaks and structural compromise. At Benson Contracting, located in Glens Falls, NY, we specialize in providing effective solutions to this pervasive problem.

Understanding Flat Roof Ponding

Ponding occurs when water accumulates on a flat roof and fails to drain or evaporate within 48 hours. This standing water can cause several issues, such as leaks, structural damage, and a reduced lifespan for the roof. Additionally, it can attract pests and promote mold growth, further compromising the roof’s integrity.

Identifying the Causes of Ponding

Several factors can contribute to ponding on a flat roof:

  • Clogged Drains: Debris can block drains, preventing water from flowing off the roof.
  • Low Spots: Over time, certain areas of the roof may settle or become damaged, creating depressions where water collects.
  • Inadequate Slope or Pitch: Flat roofs need a slight slope to facilitate water drainage. A lack of proper slope can lead to water accumulation.
  • Vegetation and Mold Growth: These can exacerbate ponding by blocking drainage paths.

Strategies for Repairing Ponding Issues

Clearing Drainage Systems

Ensuring that drains, gutters, and downspouts are clear of debris is crucial. Regular maintenance can prevent blockages that lead to ponding.

Correcting Low Spots

Filling in low spots on the roof with appropriate materials, such as roof plaster, can level the surface and promote better drainage.

Adjusting Roof Slope

In cases where the slope is insufficient, professional roofers can modify the pitch to ensure adequate drainage.

Preventative Maintenance

Regular inspections and maintenance can identify potential issues before they lead to ponding. This includes checking for and addressing any early signs of damage or wear.

The Importance of Professional Intervention

Addressing flat roof ponding is not a DIY task. It requires the expertise of professional roofers who can accurately diagnose the cause and implement effective solutions. Professional roofers have the necessary tools and expe
