What Are the Most Common Causes of Ponding Water on a Flat Roof? 

Ponding water on a flat roof is one of the most common issues that commercial building owners have to deal with. It can be caused by poor drainage, insufficient slope, or inadequate waterproofing materials. Poor drainage can be caused by blocked gutters, downspouts, or drains, and inadequate slope can occur because of improper installation or an aging roof system.

Inadequate waterproofing materials can come from wear and tear or a lack of maintenance. Luckily, there are several solutions for fixing ponding water on flat roofs. Acting quickly is important since standing water can cause structural damage and costly repairs over time. Here are some steps you can take to address the issue:

  • Check gutters, downspouts, and drains for blockages. Clean out any debris and make sure the drainage system is working properly.
  • Invest in a preventative maintenance plan to ensure your roof stays in good condition and is regularly checked for signs of wear or damage.
  • Have a professional inspect your roof slope to determine if it needs to be adjusted or re-sloped.
  • Repair any existing cracks, blisters, or seams in the waterproofing materials. If necessary, replace bad sections with new material.

Finally, adding a coating of elastomeric roof coatings can help protect your roof from future damage and extend its lifespan.

How Often Should You Inspect and Maintain Your Flat Roof to Prevent or Reduce the Risk of Ponding Water? 

The best way to prevent or reduce the risk of ponding water on your flat roof is to inspect and maintain it on a regular basis. How often you should do this depends on several factors, such as the age of your roof, the type of materials used in its construction, and local weather conditions. Generally speaking, it’s a good idea to inspect and maintain your flat roof at least once every 12 months.

During the inspection, it is important to check for any signs of damage or deterioration in the roof surface and any cracks or gaps that may have developed over time. It’s also wise to check for ponding water areas and take action if necessary. If you spot any ponding water, it is important to act quickly so that the problem does not worsen and cause further damage to your roof. The first step is to identify the source of the water, which could be anything from a blocked gutter or downspout system to poor surface drainage or frayed waterproofing seals.

How Much Should It Cost to Repair Ponding Water on Your Flat Roof? 

The cost of a repair job can vary depending on the size and scope of the project. Generally speaking, fixing ponding water on a flat roof can range from $500 to $2500 for labor and materials. This does not include any additional services that may be needed, such as removing debris or installing perimeter drains and gutters. In addition, the cost of repairing ponding water can go up if the roof is badly damaged or there are multiple areas with ponding water.

To help determine the cost of your repair job, it’s important to consult with a qualified roofing contractor who can assess the condition of your flat roof and provide an estimate for the work that needs to be done. This way, you can make an informed decision on how to proceed with the repair process and what it’s going to cost you.
