Is there a leak in the water tank on my villa roof, and how can I tell before it becomes a bigger problem? Many owners in Jeddah notice damp patches on a ceiling or a drop in water pressure without knowing where the water is escaping. Our roof tank leak detection service for villas in Jeddah starts from the local setting. The centre of Jeddah sits about 15 m above sea level, and the city is about 2 km from the sea coast, so rooftop tanks here often sit in direct sun and salty air, which can speed up wear on seams, fittings and coatings. A leak on a roof tank can also travel down walls and into rooms below, so early checking matters.
Our inspection follows a clear sequence. A technician first looks at the tank from outside and inside, checking the walls, floor, corners and joints for cracks, rust or loose fittings. The water level is then observed over a short period with the supply closed, so any drop can be noted and linked to a likely source. Inlet and outlet valves, float valves, overflow pipes and the connections to the house are examined next, since these are common points where water escapes. Where the inside surface is worn or flaking, the technician notes the affected area so the owner can see what coating work may be needed. For a tank internal coating, pricing is quoted per square metre, typically SAR 25–65 per m², depending on the surface and condition, and the final figure is confirmed only after the inspection. You receive a written summary of what was found and what options are available.
To make the visit efficient, please clear access to the roof tank and the area around it, and make sure the technician can reach the tank lid safely. Have a note of when you first noticed the problem, whether the leak appears at certain times, and any damp marks inside the villa. Turn off or let the owner know which valves are relevant, and keep the tank in its normal use if possible, so the technician can see how it behaves under ordinary conditions. Keep any previous repair records or photos on hand, as they help show what has already been done. With this information ready, the visit can focus on finding the source quickly and clearly.
In a villa, tanks, the roof and the yard lines are usually yours to look after, so it helps to know where the main valve and tank hatches are.

Tools and methods, and when we use them
| Tool | What it finds | When we use it in Jeddah |
|---|---|---|
| Dye test | Water being drawn in at openings and cracks | Limits: only for visible, nearby points |
| Documented tank level test | Level drop in numbers against time | Limits: filling and use must stop for a while |
| Moisture meter | How far the wet area spreads behind paint and tiles | Limits: measures the effect, not the source |
From the first visit to the report
- Inspecting the base and connections: We look at where water gathers and trace it back.
- Level test: The level is recorded with filling stopped.
- Float and overflow check: We confirm whether water is escaping through the overflow rather than the tank body.
- Recommendation: Repair of the connection, the float or the tank, stated in writing.

Short answers for Jeddah
Can I use household chemicals instead of calling a technician?
Using unsuitable chemicals may corrode pipes and does not fix the root cause of the blockage, so it is better to rely on a specialist technician.
What is the difference between foam insulation and other types of insulation?
Foam insulation is easy to apply on uneven surfaces and forms one continuous layer with no joints, while other types, such as bitumen rolls, need the joints to be welded. The contractor decides which is most suitable after inspecting the site.
Can thermal insulation be applied to an existing building?
Yes, thermal insulation can be installed on the roofs and walls of existing buildings without the need for major structural modifications. The contractor prepares the surface, then applies the insulating material and the protective layer over it.
