1. Drainage Problem

Unlike conventional steeped roofs, water cannot be drained out of the Flat Roof automatically. You need to provide a proper channel to let the water drain out of it. The Flat Roof’s surface should be slightly inclined to let the water easily flow out of the building. 

This requires proper leveling of the surface; otherwise, water will stand on it and cause cracks on the roof. So, a regular checkup of the drainage system is essential, especially during the rainy season. It will ensure the long life of the Flat Roof.

2. Prone to Damage

The space on the Flat Roof can be utilized for parties and other gatherings. However, this makes the roof surface prone to cracks by consistent walking over it. The process is slow but can be problematic in a few years. It means you need to take care while putting the load on the rooftop and regularly inspect the roof’s health.

3. Debris Built-Up

Flat Roofs require regular cleaning up; otherwise, debris and dirt can build up in the pipeline. It can lead to blockage in the drainage system, which causes cracks and openings in the roof. Therefore, the pile-up dirt and dead leaves are not acceptable on the Flat Roofs. 

4. Regular Inspection of Seams

Although Flat Roofs’ low construction cost is a big catch, it requires regular inspection, especially during the snowy and rainy season. If not done correctly, there can be leakages in the seam, leading to cracks and openings on the rooftop. Therefore, you must bear the extra cost of an inspection to ensure your building’s safety.
