Why Is Commercial Roof Leaking? Common Causes Of Commercial Roof Leaks

(860) 238-3113

No one wants to see water leaking through their commercial building roof. Even with regular roof maintenance, harsh weather can come through, and you can find a puddle on your floor. Our team of roofing experts has seen this happen more than we can count. But if you are prepared and maintain the leak, you can prevent further damage to your facility and the property inside. Business Insurance quotes from constructaquote.com can help to protect you from financial loss when unforeseen damage occurs to your business premises.


  • Stained Ceiling/Walls – Whether you have ceiling tiles or other types of ceiling systems in your facility, extended exposure to water will create a discolored area of your ceiling.
  • Odor/ Mold – A foul smell in your facility could be a red flag for hidden mold. Mold grows in moist environments, so if water is continuously entering your building, there is a high chance that mold could grow and spread.
  • Water Dripping/Puddles Inside – The most sure fire sign of a commercial roof leak is when you can visibly see water entering your building, whether it is a puddle on the floor or dripping above your head you need to get it fixed as soon as possible.


Poor or No Drainage

When commercial roofs are installed, the roofing contractor should take into account where the water will drain. There are multiple points of vulnerability when draining your commercial roof: drains, gutters, downspouts, and scuppers. These need to be regularly cleaned to ensure they are clear and moving water off of the roof.

When water is not draining from your roof properly, you can have standing water on your roof. This water can add a lot of extra weight on your building structure

Open Penetrations

Roof penetrations are found on many flat commercial roofs. Roof penetrations are HVAC units, vents, drains, pipes, gas lines and other systems that come through the roof membrane. While these are vulnerable areas for leaks, they can be properly sealed during a roof installation or spray coating.

Damaged Roof Flashings

Roof flashing are the pieces of metal that are installed around conjoining areas on the roof. Roof flashings are installed in areas such as chimneys, skylights, roof edges and interior walls. When a flashing is not installed correctly or, or when a metal flashing is aged, it can be damaged by wind or temperature changes, allowing water into the roof system.

Damaged Membrane

The membrane of a commercial roof is the waterproof layer. When there is damage to the membrane from the weather, foot traffic, mechanical damage or any other numerous situations, it can allow water to leak through the waterproof membrane and saturate the underlying insulation.

Sometimes there can be a quick patch to repair the area, other times you need to replace the insulation and large pieces of membrane.

Aged Roof

Most commercial roofing systems last between 15 and 20 years; this lifespan can vary depending on the type of roof you install on your facility. Our Polyuerea Waterproof Roofing Spray comes with a lifetime warranty so you never have to worry about it again.


Whether you walk into a puddle in your facility or feel water dripping on your forehead, it’s always unsettling when you are faced with a potentially costly roof project. That’s why we put together this action plan for when you are dealing with a leak in your commercial, industrial or manufacturing facility.

  1. Minimize Interior Damage – When you see water flowing into your building, clear the area of people, equipment, and supplies to reduce damage.
  2. Mark the Point of Entry – Make sure you mark where your leak is located. Marking the visible leaks is important for when you talk to your contractors and insurance agents.

  4. Call Your Insurance Agent – If your facility has received internal or roof damage, make sure you let your insurance agent know.
