The answer to 'why is my flat roof leaking' is that there are several common causes, including poor installation, damage from weather and UV exposure, and lack of maintenance. Flat roofs are more prone to leaks than pitched roofs because they don't have the same natural drainage. Over time, the waterproof membrane can deteriorate, allowing water to seep through and cause interior damage.
Some of the main symptoms of a leaking flat roof include visible water stains on the ceiling, mold or mildew growth, and pooling water on the roof surface. If left unaddressed, a leaking flat roof can lead to structural damage and costly repairs. In many cases, the best solution is to call in a professional roofing contractor to inspect the roof and make the necessary repairs or replacement.
