Flat Roof Leaking Problems

Here are a few of the most common and easy to recognize signs of roof problems.

Flat roof leaking problems. Leaks and moisture another common problem with flat roofs is leaks. Some roof leaks are tough to locate. However in my own experience the problems with leaking flat roofs are usually as a result of either poor workmanship installing the roof membrane poor maintenance by the building owner or as a result of age. A leak in a flat roof can lead to eventual collapse and tons of property damage if you re not careful.

But since it s a flat roof the water doesn t have anywhere to go but straight down. If your ceiling has a plastic vapor barrier between the drywall and the attic insulation push the insulation aside and look for flow stains on the plastic often water runs to openings in the vapor barrier such as at ceiling light fixtures. The problem with finding a leak in a flat roof that sets it apart from finding one in a sloped roof is that the water can run in any direction. So all you need to do is simply follow it up to its source.

Roof leveling can resolve minor drainage issues but more serious issues of ponding require changes to the underlying roof structure itself. With a traditional sloped roof a leak can be found quite easily as water will flow in a downward motion. But you can avoid the bulk of these problems with regular maintenance. It s a good idea to inspect your roof regularly.

Metal flashing that runs alongside a wall loosens up or the caulking gives and a major leak starts. In addition to leaks this can cause premature problems with the roof membrane and may void the guarantee limit traffic and conduct cursory inspections after tradespeople have been on the roof. Take a screwdriver or flat bar and see if the caulking that seals the top of the metal flashing is still holding. Flat roofs aren t actually flat.

But even if you have to pay it s better than finding leaks after the damage is done. First of all we should clear up a common misconception. Flashing is the number one cause of leaks on flat roofs. If your roof vent leaks during heavy rain the rain may be blowing up under the hood and into the vent.

Leaks and moisture probably the most common problems with flat roofs leaks and lingering moisture are issues that can be dealt with effectively as long as you stay on top of them. Sometimes the water shows up at a ceiling spot distant from the leak. A small leak can go undetected for years causing huge damage before you notice anything. All roof systems performance is compromised when new equipment and penetrations are added to an existing roof unless proper precautions are taken.

Flat roofs are known as being problematic with many suffering leaks. Just like any roof a flat roof will develop leaks but since it s flat the water doesn t have anywhere to go but straight down. Many contractors offer free inspections.
