No day is a good day to have a dreaded leak. None of us plan to have to deal with our failing roof during our regular busy days in the office. Omnipresence has put together a list of the most common reasons why a roof may leak. The list below can be used as preventative maintenance! Have your experienced roofer do a thorough maintenance check twice a year!


  1. Roofing System Is Aging: Age diminishes the effectiveness of a roof, as we all know. Did you know that most flat roofs only last between 15-20 years? After that, the deterioration is rapid. If problems of leaking persist after this age, after attempts to fix, patch or even restore, it will most likely need to be fully replaced. A roofing expert with a trained eye will know for sure if it can be repaired or will need to be replaced.
  2. Perimeter Flashing: If flashing around the exterior edges of the building or parapet walls has not been installed correctly or is damaged or loose then the roof is exposed to the elements and moisture penetration is inevitable. Due to extreme weather and temperature changes in Texas, flashing can take a beating. It is a good practice to keep a close watch over your flashing for any changes, tears, or damage to prevent future issues.
  3. Ponding Water and Clogged Drains: Ponding water is typically caused by poor drainage, clogged drains and possibly an improper roofing installation. Ponding can cause dirt and debris to accumulate and create rot, algae and bacteria to grow, impacting the effectiveness of your roofing system and will destroy the roof coating and membrane. It is important to check the drainage system often to ensure the water is flowing through the proper drains and downspouts and make certain there are no clogs.
  4. Roof Penetrations: Roof penetrations such as HVAC units, electrical conduits, roof vents, pipes, hot stacks and gas lines are very susceptible to roof leaks. Water barriers like flashing, field wraps, rain collars, pipe boots and pitch pans (to name a few) are used to protect these penetrations within the roofing system from leaks, however should be inspected often to make sure they are still performing properly. Any damage or deterioration of these systems can cause leaking to occur.
  5. Membrane Damage: The membrane is your primary water barrier and is vital to the success of the roof performance. If the membrane is split, cracked or punctured there is easy access for water to penetrate through to the interior of the building.
