Pooling water on your commercial roof isn’t just an eyesore—it’s a serious issue that can lead to significant damage and costly repairs. If you’ve noticed water gathering in certain areas of your roof after a rainstorm, it’s time to take action. Below, we discuss why pooling water is problematic and what you can do to protect your building. When you need commercial roof repair in Springfield, OR, or the surrounding areas, contact the experts at JLN Roofing & Construction Inc. to get started.


Structural Damage and Leaks

When water pools on a roof, it creates excessive weight and puts stress on the underlying structure. Over time, this constant pressure can weaken the roofing system, leading to cracks and eventual leaks. Once water seeps into the building, it can damage insulation, interior walls, and even the building’s framework. Not only does this compromise the integrity of your roof, but it can also lead to mold growth and other indoor air quality issues that affect the health of your employees and customers.


Accelerated Deterioration of Roofing Materials

Pooling water is a catalyst for accelerated wear and tear. Many commercial roofs are made of materials designed to shed water quickly—such as built-up roofing (BUR) or single-ply membranes. When water stagnates, it can break down these materials, causing them to degrade faster than normal. This deterioration can lead to more frequent repairs or even premature roof replacement, impacting your business’s bottom line.


Reduced Energy Efficiency

A roof that is in poor condition due to water pooling can also affect your building’s energy efficiency. Leaks and water damage often force you to run additional HVAC systems to maintain indoor comfort, which in turn increases energy consumption. Moreover, damaged roof materials may lose their reflective properties, leading to higher cooling costs during the hot months.


What You Can Do

Addressing pooling water promptly is critical. Regular roof inspections by a qualified professional can help identify problem areas early. Installing proper drainage solutions, such as additional downspouts or roof drains, can ensure water flows off your roof instead of pooling. In some cases, regrading or applying a new roof coating may be necessary to create a more effective water-shedding surface.
