After seeing all the benefits of having a flat roof, we have to put an accent to all of its drawbacks. It is important to know all the cons to understand whether this is the roofing solution you want to install.

1. Better for smaller facilities

Flat roofing systems tend to lose their qualities on larger objects much quicker than on smaller facilities. Although they are relatively durable, it is always better to use this option to its full potential.

When there is direct sun exposure, some of the materials can get damaged and the whole construction can be at risk. For that reason, it is not completely advisable to use them primarily in larger buildings.

2. Their life is limited

Like every other construction piece, flat roofs have their limits. This means that they can last for a specific time before they need to be replaced. In general, you can expect this roofing system to last for at least ten to fifteen years.

On the other hand, their affordability compensates for their soon replacement. You will not have to spend much, and they are quickly installed for a short downtime.

3. Complicated drainage systems

Unlike the pitched roofs where the water slides off them easily, in the flat systems there has to be a good drainage system installed.

It is already known that pooling can occur on flat surfaces, however, the drainage system is here to let all the water out. Although they are complicated, many companies have specialized in their installation process, so you shouldn’t worry.

4. Membranes get damaged

The flat roofing system is covered with membranes that completely protect the construction. With time, these membranes can get damaged and water can get inside the building. For that reason, regular inspections are necessary for preventing such situations.

The membranes usually get damaged by direct sun exposure, so they shrink and open spaces for water to get in. However, there are products with higher quality that withstand hot conditions better. Make sure to talk with the roof installation firm and use materials that are most suitable for your situation.
