by | Feb 9, 2024 | Blog | 0 comments

Understanding Flat Roof Ponding

Flat roof ponding is a prevalent concern among homeowners and property managers. It refers to the accumulation of water on flat roofs after heavy rainfall or storms. Unlike sloped roofs, where water typically drains away or evaporates within 48 hours, flat roofs can retain water, leading to prolonged ponding. This phenomenon is not just an aesthetic concern; it poses significant threats to the structural integrity of the roof and the overall property.

The Implications of Ponding on Your Roof

When water remains stagnant on a roof, it can have several detrimental effects:

  • Concentration of Sunlight: The pooled water can act as a magnifying glass, focusing sunlight on specific areas of the roof. This can increase the internal temperature of the property, leading to higher cooling costs.
  • Accumulation of Debris: Over time, ponding water can attract dirt, leaves, and other debris. This not only adds weight to the roof but can also lead to blockages in drainage systems.
  • Deterioration of Roofing Materials: Continuous exposure to stagnant water can weaken even the most water-resistant roofing materials, leading to leaks and potential structural damage.

Addressing the Ponding Issue

Structural Assessments

If your property is experiencing ponding, the first step is to assess the structural integrity of the roof. Super Roofers, one of the leading roofing companies in Mobile AL, recommends a thorough inspection of beams, frames, and other structural components. Any deformities or damages can hinder proper drainage and need immediate attention.

Drainage System Check

A well-maintained drainage system is crucial for preventing ponding. Regularly inspect for obstructions or blockages that might impede the flow of water. Simple plumbing issues can often be the culprit behind significant ponding problems.

Roof Surface Evaluation

Frequent foot traffic or the installation of heavy equipment like air conditioners can create indentations on the roof surface. These depressions can become water collection points. It’s essential to ensure that the roof surface is even and free from protrusions that might contribute to ponding.

Proactive Measures for Flat Roof Ponding

  • Regular Inspections: Engage roofing contractors Mobile AL, like Super Roofers, for periodic inspections to identify potential problem areas before they escalate.

  • Invest in Quality Roofing Materials: Opt for water-resistant and durable roofing materials that can withstand the challenges posed by ponding.
