If water is still standing on your flat roof a few hours after it has rained, it’s a sign that your roof’s drainage systems aren’t working. When pools of water sit on your roof for too long, they can cause water damage. This can be anything from damage to the roof’s surface to damage that goes all the way through the membrane. Wouldn’t you rather just have a few water spots after a small repair than have to replace the whole roof? Talk to a roofing expert right away.

Growing Mold

Mold growth is a sign of damage to a flat roof because mold won’t grow unless the water is already inside your roof in places it shouldn’t be. If you catch mold growth early, it’s easy to get rid of, but a lot of molds can be a sign that something more dangerous is going on. If your business is open to the public, it’s your job as a business owner to make sure that your customers and employees are safe. Before you let people live or work in the building, you should have commercial roofing contractors check to see if your roof is structurally safe under the mold.

Splits in the Paint

Small cracks on your roof aren’t always a huge red flag, but if you have TPO roofing, which is a popular type of eco-friendly flat roofing, and you see a lot of cracks or cracks that are especially deep, you might need to reapply the coating. When this happens, sometimes all that needs to be done to fix the roof is to fill in the cracks and reapply the coating. However, if the cracks are deep enough, professional roofers might need to add a few more protective layers or decide that you would be better off with a different type of roof.

Flashing that is loose or missing

Seams are what hold flat roofs to the house itself. Flashing is what covers these seams, and it does a very important job of protecting seams from wear and tear. If your flashing is coming loose or missing pieces, it’s time to call in professionals. Keeping your flashing in good shape can be a simple and cheap way to make your roof last longer.

Membranes Split

EPDM roofs, which are sometimes called rubber roofs, have black surfaces called “roof membranes” that are the first line of defense against the weather. With a flashlight and a close look, rips or tears in this roof are easy to spot because the surface is dark and almost rough. Small rips and tears can be fixed, but larger tears could mean that your roof isn’t structurally sound because it has been exposed to water or ice for a long time. No matter what kind of tears you see in the membrane of your roof, we suggest fixing the roof to keep your building safe and dry.


If the ceilings closest to your roof keep getting wet, it could be a sign that your flat roof is damaged. A roof leak is dangerous because it means that water has gotten into every layer of the roof, which could mean that the whole roof needs to be replaced. Sagging ceilings are a bigger problem than drips or leaks. If any of your ceilings are sagging, you should call roofing contractors as soon as possible. This is one of the signs that a roof collapse could happen, so it could save your life or property.


Your roof system is more complicated than you might think, and it takes a lot of care to make sure it works right. Taking care of your roof now is the best way to keep it safe in the future. Schedule a roof inspection every six months to a year to catch small problems with a flat roof before they get worse.
