5 Most Common Flat Roofing Problems

– How Dominion Roofing Can Help  

For many years, flat roofs have been a logical implement for certain types of buildings. If you own a commercial building or have a unique home that has a flat roof, you probably already know that your flat roofing can be a little needier than traditional roof shapes. The shape and function are fairly simplistic and the roofing itself is straightforward, but to prevent ongoing problems, you have to be attentive to maintenance and issues that your flat roof can have. Take a look at five of the most common flat roofing problems.

1. Problems with Flat Roofing Leaking

Most flat roofs that are well-maintained and in good condition do exceptionally well about preventing water leaks. However, one of the most common problems with flat roofing is still water leaks. As the membrane breaks down, water can seep into small cracks and crevices and lead to leaks inside the building.

2. Buckling of the Flat Roofing Membrane

A flat roofing membrane can buckle for a few different reasons. However, the typical cause for a flat roof to buckle is if the building shifts, which is most commonly a problem with older buildings. The membrane that goes down on top of the roof forms into a solid protective piece as it cures. If the building shifts or settles, it can cause the membrane to buckle.

3. Cracked Roofing Membrane

Since a flat roof is not slanted, there is a lot of pressure on the roof, and this pressure can lead to cracks. The cracks are in the roofing membrane, which can be made out of several different types of materials depending on what was originally installed to protect the roof. For example, roofing membrane can be formulated out of:

  • Tar
  • Plastic polymers
  • Fine aggregate like sand

Over time, the solid membrane can develop cracks and fissures. If these imperfections are left alone, they can start to widen and get worse with time, which can lead to leaks, pooling, and further deterioration of the roofing materials.

4. Loose Metal Flashing

The flat roofing membrane can easily expand and contract with changes in the environment and climate. Unfortunately, this consistent change in the membrane’s structure can cause the protective metal flashing around certain components to work its way loose. You may see metal flashing flapping in the wind or find a piece of broken flashing on the ground. These pieces protect the vulnerable areas of the roof, which means they should be replaced or repaired quickly to thwart bigger problems.

5. Pooling Water on the Flat Roof

Even though flat roofs are definitely flat, they should be designed in a way that deters the pooling of water. If water is allowed to pool on the surface of the flat roofing membrane and stay there, it can lead to the breakdown of the materials. Therefore, if you are seeing puddles on top the roof, it is best to have a roofing technician take a look. In most cases, these areas where water is pooling can be mended so the water will flow away properly.

FAQ’s

What can cause cracks on my flat roof?

Your flat roof may be less noisy but cracking is possible for various reasons. The most obvious reason is that a flat roof will not withstand much pressure as compared to a slanted roof.

Should I worry about frequent pooling of water on my flat roof?

Frequent pooling of water on your flat roof should definitely worry you. A good roof should ideally allow evaporation or draining of any water that lands on it.

Why is it important to quickly address damaged roof flashing?

Your roof flashing system is important because it prevents unwelcome leaks more effectively. Regular maintenance will pinpoint hidden damage.
