The answer to 'flat roof damaged' is that there are several common causes, including water pooling, poor drainage, age and wear, and damage from weather or debris. Symptoms can include leaks, sagging, cracks, or blisters in the roof membrane. Solutions may involve repairing or replacing the roof, improving drainage, or addressing the underlying cause.
For minor issues, some basic repairs like patching cracks or sealing leaks may be suitable for a DIY approach. However, for more extensive damage or complex problems, it's best to call in a professional roofing contractor. They can properly assess the situation, identify the root cause, and recommend the most effective long-term solution.
