Common Commercial Roofing Problems and How to Fix Them

The roof of your commercial building is a critical component that protects your investment and ensures the safety and comfort of your employees and customers. Over time, however, commercial roofs can develop issues that require attention. In this blog, we will discuss some of the most common commercial roofing problems and provide insights into how to address them. While some minor maintenance tasks can be handled in-house, it’s essential to consult with professional roofing experts to ensure the long-term integrity of your roof.

  1. Leaking Roofs:

    Leaks are perhaps the most common roofing problem faced by commercial property owners. They can be caused by various factors, including damaged flashing, punctures, or deteriorating roofing materials. Leaks not only compromise the structural integrity of your building but can also lead to costly water damage and mold issues.

    How to Fix It:

    When you notice signs of a leak, such as water stains on ceilings or walls, it’s crucial to act promptly. Contact a professional roofing contractor to assess the source of the leak and make the necessary repairs. Roofing experts have the knowledge and equipment to detect leaks accurately and address them effectively.
  2. Ponding Water:

    Ponding water occurs when water accumulates and doesn’t drain properly from the roof’s surface. This can result from poor drainage design, clogged drains, or sagging areas in the roofing structure. Over time, ponding water can weaken the roof’s structure and lead to leaks.

    How to Fix It:

    Proper drainage is key to preventing ponding. Consult with a roofing professional to evaluate your drainage system and make the necessary adjustments. They can ensure that water flows away from the roof efficiently, mitigating the risk of ponding.
  3. Blistering and Bubbling

    Blisters and bubbles on the roof membrane are often caused by trapped moisture, improper installation, or exposure to extreme temperatures. These issues can weaken the roof and reduce its lifespan.

    How to Fix It:

    Addressing blistering and bubbling requires professional expertise. Roofing contractors can determine the underlying causes and recommend appropriate solutions, which may include repairing or replacing affected sections of the roof.
  4. Cracked or Damaged Flashing

    Flashing is essential for preventing water from seeping into the joints and seams of your roof. When flashing becomes cracked or damaged, it can compromise the roof’s waterproofing abilities.

    How to Fix It:

Replacing damaged flashing is a job for experienced roofing professionals. They can ensure that new flashing is properly installed and sealed, preventing further water infiltration.

  1. Roof Membrane Deterioration

    Over time, the roof membrane can degrade due to exposure to the elements, UV radiation, and temperature fluctuations. When the membrane begins to deteriorate, it loses its effectiveness in keeping water out.

    How to Fix It:

    Replacing the roof membrane is a complex task best left to professional roofers. They will select the appropriate membrane material for your building’s specific needs and ensure a proper installation that maximizes durability and waterproofing.
  2. HVAC and Ventilation Issues

    HVAC units, vents, and other rooftop equipment can create potential vulnerabilities on your commercial roof. Improper installation or maintenance of these components can lead to leaks and damage.

    How to Fix It:

    Regular inspections and maintenance of rooftop equipment are essential. Ensure that HVAC units are properly installed and maintained to prevent them from damaging the roof. If issues arise, consult with roofing professionals to address them promptly.
  3. Storm and Hail Damage

    Severe weather, including storms and hail, can cause significant damage to commercial roofs. Hail can puncture the roof membrane, while strong winds can lift or tear off roofing materials.

    How to Fix It:

    After severe weather events, it’s crucial to have your roof inspected by professionals. They can assess the extent of the damage and recommend necessary repairs or replacements. Prompt action can prevent further damage and protect your investment.


Maintaining a commercial roof in good condition is essential for the longevity and integrity of your building. While some minor issues can be addressed with routine maintenance, it’s important to consult with experienced roofing professionals for more significant problems. Regular inspections, proactive maintenance, and timely repairs are key to preventing costly damage and ensuring that your commercial roof in Houston continues to provide reliable protection for your property. So, when faced with roofing problems, don’t hesitate to seek the expertise of qualified roofing experts to address them effectively and safeguard your investment.
