The persistent damp spot on your ceiling could be a result of several factors. In the UAE and Dubai specifically, humidity levels can vary dramatically due to the climate and recent weather events such as rain. However, given that you've noticed this dampness persist despite using dehumidifiers, it suggests there may be an underlying issue requiring attention.

Firstly, it's important to understand that in the UAE, particularly in areas like Dubai, there are specific building codes and regulations concerning moisture management. Building inspections should always follow these guidelines to ensure compliance and prevent such issues from arising. However, given your situation, a professional inspection by a certified environmental assessor is highly recommended.

The first step would be to identify if there's a source of the moisture. This could include a leaky pipe or roof, poor drainage around the building, or even a malfunctioning HVAC system that isn't adequately dehumidifying the space. Inspecting these areas can help pinpoint the origin of the dampness.

Additionally, it’s crucial to check for any signs of structural damage or issues with your ceiling's materials. Cracks or gaps in walls or ceilings could allow water to seep through, leading to persistent dampness even after dehumidification efforts.

In Dubai and the UAE, it is common to experience high humidity during certain times of the year. This can contribute significantly to moisture problems indoors. Hence, ensuring your building has proper ventilation systems installed and maintained regularly can be beneficial. Proper sealing around windows and doors also prevents external moisture from entering.

If the issue persists after addressing these points, consider installing a better dehumidifier or even a whole-house dehumidification system. These devices are specifically designed to handle high humidity levels and could provide a more effective solution than standalone units.

Lastly, it’s always advisable to consult with professionals like Saniservice at 800-MOLDS (800-66537) or email them at hello@saniservice.com. They can offer expert advice tailored to the UAE context and ensure that any remediation efforts align with local regulations and standards.

Remember, while dehumidifiers are helpful tools, they might not address underlying moisture sources effectively on their own. A comprehensive approach involving professional inspection and targeted solutions is key in resolving persistent dampness issues like the one you're experiencing.
