Small Business Owners: Flat Roof Inspections And Preventative Maintenance

As a small business owner, it is vital that you stay informed about the condition of your building's flat roof. Proactively monitoring your building's roof's condition will help to prolong its useful life. 

Since major commercial roof repairs are costly, it is always best to catch problems when they are still small and can be easily repaired. Over the course of a decade, a simple yearly roof inspection can save your business thousands of dollars in repair costs if a minor repair issue turns into a situation where you need a new roof.

Here are several things that you should watch for, each of which can signal major problems with your building's roof:

Standing Water on Roof

Standing water on your building's flat roof an cause problems with:

  • rusting steel
  • rotting wood
  • dissolving insulating concrete 

In addition, standing water can cause damage due to its excessive weight. Water weighs eight pounds per gallon, so it does not take too much water to provide a lot of weight that your roof is not designed to hold.

To avoid problems that result from standing water, you should check your roof after it has rained. Make sure that your roof is properly draining. If you see puddles of water, then you need to have a roofing contractor come to your location and determine the problem.

Bubbling on Roof Surface

Sometimes the natural gases that escape from roof underlayments can cause bubbling in the roof's outer surface. If you can see bubbling on the surface of your roof, then you need to have someone fix that section of the roof. The roofing material will need to be patched to prevent the gasses from completely bursting a hole in the roof. If this happens, then your roof will leak water into the underlayment and cause damage.


Metal flashing is used on flat roofs in order to keep water from penetrating the roof where:

  • seams meet
  • vents are located
  • rooftop equipment is located

In addition, flattop roofs also have a layer of flashing around their entire perimeter.

Winds can cause flashing to become loose and leak water. For this reason, you should check all of the flashing on your roof to ensure that it is safely attached to the roof and there are no loose places.

Lightning Control Cables

Finally, if your building has a lightning control cable installed in the roof surface, you should check to make sure that the wind has not blown it loose. A loose lightning control cable can cause the roofing area to leak where the cable came dislodged from.

If you have any questions about your small business's building's roof, then you should contact a local commercial roofing company, such as P Cooper Roofing, for more information.
