3 Main Causes Of Flat Roof Leaks

In our 30 years of experience in commercial and industrial flat roofing systems, we have seen nearly every type of roof leak that exists. The causes can be narrowed down to three, especially for flat roofing systems. We not only help businesses identify potential roofing issues, but also provide the best possible solutions, such as an emergency roof repair services.

The 3 Main Reasons:

Standing Water

The number one reason for flat roof leaks is stagnant or standing water. Water can stagnate during any time of the year but the problem is aggravated during fall and spring. The design of flat roofing systems is such that water may not drain out as quickly as it does from a sloped roof. The accumulated water may likely make its way through the gaps in the roofing system and into the building.

Roof leaks happening due to water accumulation can be prevented by taking adequate care during the installation process. NorthCan Roofing recommends using durable waterproof membrane materials and watertight seals. It is equally important to ensure that all drainage routes are clear and free from any blockages to allow water drainage to happen smoothly.

Blocked Drainage

The blocked drainage routes is the second most important reason for flat roof leakages. Plant debris such as stray leaves and pieces of branches can cause major blocks in the drainage system. This can prevent smooth and proper drainage of water and lead to serious water damage in the building.

Regular, as well as seasonal roof maintenance can help prevent blocked drains. If a major storm has struck the area, it makes sense to schedule an extra maintenance session so that all the additional debris brought in by the wind can be quickly disposed off and the drainage systems cleaned and cleared.

Extreme Weather Fluctuation

Extreme fluctuations in the weather is the third key reason for flat roof leakages. When the weather fluctuates dramatically from hot to cold or vice versa, there is a possibility that the flat roof will expand and shrink at a rapid rate.

These may seem like minor changes, but the sudden nature of the movements can result in the creation of minor holes and small cracks in the roof system. Left unattended, these cracks can allow water to seep into the roof system and cause gradual damage to the structure.
