How To Fix Your Commercial Roof Leaks

When you have a commercial flat roof, stagnant water is often a problem. Stagnant water is water that remains trapped for days, even weeks. On commercial flat roofs, stagnant water can lead to significant damage to your roofing system and insulation over time. If left untreated, these areas will also become breeding grounds for mold and mildew, which can pose health risks to building occupants and costly clean-up costs for commercial property owners.  

This blog post will explore 3 solutions that commercial property owners have used successfully to address stagnated water on their commercial flat roofs!


3 Ways Of Draining Water From Your Commercial Roof

  • Install Commercial Grade Roof Drains
    In most cases, commercial flat roofs are designed to have an inlet that takes rainwater from the entire rooftop and funnels it into one commercial-grade downspout. If you don’t have this kind of drainage structure already built on your commercial property, then adding one is the best solution. Because commercial buildings are occupied most days of the year, you need commercial roof drains that can prevent water being trapped.
  • Pump Out Excess Water After Heavy Rains
    Pumping out excess water after heavy rains is a good way to prevent stagnant pools on commercial roofs. This also helps keep commercial flat roof structures clean and prevents the risk of mold or mildew growth inside commercial buildings. After heavy rainfall, it is ideal to remove the excess water by using a pump.
  • Hire A Commercial Roofing Contractor
    Hire a commercial roofing contractor to remove old deteriorated shingles and replace them with new ones. This prevents standing water from getting trapped between the layers of roofs.


Stagnant water can lead to the growth of mold and other organisms that will ruin the appearance of your commercial building and cause health concerns for employees working inside. Ensure proper ventilation for your commercial building so that steam can escape and airflow is not hampered.

Replace commercial flat roofs when they become damaged or deteriorated. This will prevent water from getting trapped between the layers.
